The Ultimate Guide to Umbrella Companies

As a contractor, one of the key decisions you’ll face is determining the best way to provide your services to clients. Should you work through an umbrella company, establish your own limited company, or operate as a sole trader? Each option comes with its own benefits, challenges, and legal implications.

Navigating complex issues like the IR35 legislation can make choosing a working arrangement feel overwhelming. Understanding umbrella companies, how they work, when to use them, and what sets them apart from other structures is essential. With so much information to digest – from taxes and fees to payslips and compliance – it’s no surprise that contractors often seek clarity.

This comprehensive guide is here to simplify the process. We’ll cover everything you need to know, from answering common questions like “How does an umbrella company work?” to the minutiae of National Insurance, pensions and holiday pay.

While this guide offers valuable insights, it’s not a substitute for professional advice. Contractors must stay informed about HMRC regulations, which can be complex and subject to change. Always consult an expert if you’re unsure about your legal or financial obligations.

The Ultimate Guide to Umbrella Companies - Topics Overview

What is an Umbrella Company?


Umbrella companies act as employers to contractors for the length of a specific engagement, turning the self-employed into taxable employees. They employ contractors working on temporary assignments, serving as intermediaries between contractors and their clients (the end client or recruitment agency).

Key takeaways

  • An umbrella company is commonly used for Inside IR35 contracts, managing administrative tasks such as invoicing and processing payroll.
  • Contractors sign an employment contract with the umbrella company, submit timesheets, and receive payments via PAYE after deductions for taxes, National Insurance, and the service fee.
  • Legitimate umbrella companies adhering to HMRC rules are safe; contractors should avoid any that claim to offer tax advantages.
  • Umbrella companies are ideal for contractors working Inside IR35 or for short-term contracts, while limited companies suit long-term contractors with Outside IR35 contracts.

‘Umbrella Company’ meaning

The term ‘Umbrella Company’ refers to the fact that the business provides administrative services to many contractors simultaneously. Unlike limited companies, it is not unique to the individual. While the concept of an umbrella company may seem counter-intuitive to being self-employed, they serve a required niche created by the introduction of IR35.

The role of an umbrella company is administration-focused. They manage timesheets, invoice the relevant party on behalf of the contractor, calculate and pay the required taxes and National Insurance Contributions, and pay the remaining monies to the contractor (less any fees/margin for services rendered).

As contractors become employees for the time they work through an umbrella company, they are no longer subject to IR35 checks. As such, umbrella companies are the most popular choice for those required to work Inside IR35. In fact, clients often stipulate that contractors must work through an umbrella company if the contract is Inside IR35.

How does an umbrella company work?

Although it can seem complicated in theory, the mechanics of working through an umbrella company are relatively straightforward:

1

Sign a Contract

Once you have decided which umbrella company to work through, a contract of employment is signed between yourself and the umbrella company, effectively making you an employee of the umbrella company for the length of the contract.
As an umbrella company employee, you have no actual contractual relationship with the end client. Instead, the umbrella company will sign an agreement with your recruitment agency or end client, the details of which (contract rate, hours worked, etc.) you have already agreed to.
If your agency/client and the umbrella have an existing relationship, this process should be simple, using agreed terms and only requiring confirmation of specific details. If no current relationship exists, this process will be slightly longer as both sides perform the necessary due diligence.

2

Working and Timesheets

Once you start working, you must provide a timesheet detailing work hours for each contractually agreed payment cycle (usually weekly). These are typically submitted through an online portal and countersigned by your client.

3

Invoicing and Taxes

The umbrella company will invoice the end client directly; the amount is determined by the contractually agreed rate and the number of hours recorded in Step 2. The umbrella company will then deduct employment costs and their margin from the amount received.

4

Payment

The remainder (minus any pension contributions) will be paid to the contractor via PAYE, ensuring all required taxes are paid directly to HMRC. This payment is made directly into the contractor’s personal bank account, meaning there is no need to set up a separate business account. The contractor will receive a payslip with a detailed breakdown of the deductions.

Are umbrella companies safe?

There is a common misconception that umbrella companies have unethical practices around handling payments to contractors. Umbrella companies that comply with HMRC’s rules are perfectly safe. If an umbrella company follows the rules correctly, take-home pay should never vary. The only deduction that varies among different providers is the margin, the fee umbrella companies charge for their services.

Contractors should treat any umbrella company that claims they can provide tax advantages with extreme caution! All umbrella companies must follow HMRC’s tax rules and regulations in the same way as any employer. There is almost no room to manage your tax liability advantageously once you enter PAYE.

What is the difference between an umbrella company and a limited company?

A limited company is a separate legal entity through which business is conducted; all liability lies with the business rather than the owner(s). An Umbrella company employs contractors working on temporary engagements; acting as intermediaries between contractors and their clients, with their primary responsibility being to organise payment for work performed.

While some specialists may recommend one direction over the other, contractors should be wary of service providers promoting their own self-interests. There is no one-size-fits-all approach, instead, you’ll need to consider IR35, length of contracts, earnings, and how much control you’d like.

I

Employment Status

Employment status is the primary difference between operating via a limited company and an umbrella company. Contracting via a limited company means you are self-employed. You are both a director and a shareholder with complete control. It is your responsibility to sort out the company’s financial and administrative affairs and ensure the correct tax is paid (both business and personal).

Umbrella companies act as employers to contractors for the length of a specific engagement, effectively turning the self-employed into taxable employees (thus becoming eligible for PAYE). While contractors retain the flexibility to set their own working conditions (via contract negotiations), most of the administration is done by the umbrella company.

II

Getting Paid

As a limited company contractor, you must negotiate payment terms and invoice clients for work performed. You must set up a business bank account, register for VAT if required and submit HMRC-compliant invoices. If no payment terms are agreed upon, the law assumes a standard 30-day payment period exists. The client will pay your company directly, and you can then pay yourself.

An umbrella company is essentially an invoicing vehicle for contractors; it allows them to avoid the administrative duties involved in payment processing. Contractors working through an umbrella service will submit timesheets and leave the rest to the umbrella company. They will invoice the client on your behalf, and the client will pay the umbrella company, which, in turn, will pay you.

III

Tax

Provided your contract falls Outside IR35 (see IR35 considerations below), one of the main benefits of contracting via a limited company is that it is the most tax-efficient way to operate. Limited company contractors can access various expenses and tax allowances.

They have great flexibility over when to take income from the company, pay themselves a tax-efficient combination of salary and dividends, and even transfer shares to a spouse (if appropriate).

Unfortunately, there is very little contractors can do to minimise their tax liabilities when working through an umbrella company. As umbrella company employees, contractors are subject to the same Income Tax (via PAYE) and National Insurance Contributions as permanent employees.

Contractors must also cover employment costs (such as Employer’s National Insurance Contributions) out of the agreed-day rate.

IV

Admin

If you set up a limited company, you become a company director with many financial and statutory responsibilities. HMRC and Companies House (the official registrar of companies in the UK) both have tax and reporting obligations that need to be met.

As a director, it is your responsibility to meet these obligations. Given the complexities involved and the penalties for getting something wrong, most contractors employ a specialist contractor accountant to help run a limited company.

An umbrella company acts as a contractor’s administrative vehicle, meaning contractors avoid the hassle of dealing with any paperwork. Contractors submit their timesheets detailing hours worked for each contractually agreed payment cycle, and the umbrella company does the rest. They issue invoices, calculate the relevant tax and National Insurance Contributions, and chase outstanding payments. All the contractor needs to do is work.

IV

Expenses

Whether a contract is Inside or Outside IR35 determines what expenses a contractor can claim.

As a limited company contractor working Outside IR35, you can claim tax relief on several business expenses. So long as the expense was incurred wholly and exclusively for the purposes of running the business, the costs can be offset against Corporation Tax payments.

Prior to April 2021, contractors working Inside IR35 via an umbrella company were entitled to claim a 5% general expense allowance on the value of the contract. This 5% was given at a flat rate, calculated on the gross fees receivable, and there was no requirement to provide receipts or other proof of expenditure. Since April 2021, new rules have been introduced which significantly curtail who can claim the 5% allowance. For all public sector and most private sector contracts, the 5% allowance no longer exists. The only exception is if the contract is in the private sector and the client is deemed a ‘small company’.

Advantages and disadvantages of an umbrella company

The main advantages and disadvantages of an umbrella company are:

Admin-free

ADVANTAGE

An umbrella company will handle the administrative tasks usually involved in running a business. They will take care of invoicing, compliance with legislation, and calculating taxes and National Insurance. All you need to do is submit timesheets.

Easy To Get Started

ADVANTAGE

Compared to incorporating a limited company, getting started with an umbrella company is more accessible. All you need to do is choose an umbrella company, sign a contract, and you’re good to go.

Non-Committal

ADVANTAGE

Given how easy it is to start with an umbrella company, they are great for those only looking to contract for the short term. If you are unsure whether contracting is for you, it may not be worth the investment, administratively and financially, to set up a limited company.

Increased Tax Liability

DISADVANTAGE

An umbrella company is not as tax-efficient as trading via a limited company. With no access to dividends, all income will be taxed through PAYE. In addition, you will be responsible for both employee and employer National Insurance Contributions.

No Expenses

DISADVANTAGE

Since April 2021, new rules have been introduced that significantly curtail when and what expenses can be claimed when working through an umbrella company.

Contractors and umbrella companies

If your contract is deemed to be Inside IR35, then the benefits of contracting via a limited company become obsolete. You are considered an employee for tax purposes, meaning you pay Income Tax and National Insurance at the same level as a company employee.??

Contractors that continue to work via a limited company while Inside IR35 will have taxes deducted at source by the fee payer (the end hirer or agency). The fee payer will allocate a tax code and make the relevant National Insurance and Income Tax deductions.

The remaining amount is then paid to the limited company along with any VAT owed. As the fee payer has already deducted tax from the monies paid to the limited company, the contractor does not need to pay any further personal taxes (income, NICs, or dividend), and the company does not need to pay any Corporation Tax on the received amount. This avoids any issues related to double taxation.

Working Inside IR35 via a limited company is not tax-efficient as you will still incur expenses involved in running a business (accountancy costs, insurance costs, etc) while also maintaining the responsibilities of filing accounts and tax returns.

While it is technically possible to continue to work through a limited company if your contract is Inside IR35, most clients will refuse to engage you. They will have preferred methods of engagement, usually via an umbrella. As such, if you find yourself working Inside IR35, you may have no choice but to operate through an umbrella company.

A limited company is right for you if:

• Your contract is Outside IR35, and

• You intend to contract for the long term.

An umbrella company is right for you if:

• Your contract is Inside IR35, or

• You only intend to contract for the short term.

Sole trader contracting is rarely a viable option; almost all agencies and clients will reject contractors operating as such. It exposes agencies and clients to employment tribunals, and the unlimited liability exposure makes it less appealing for contractors.

Tax and Pay


Umbrella companies manage contractor pay via PAYE, deducting taxes, National Insurance, and employment costs like Employer’s NICs and Apprenticeship Levy. Although detailed payslips are provided, the terminology used (including the difference between assignment income, gross pay, and net income ) can often be confusing to new contractors.

Key takeaways

  • Umbrella companies provide detailed payslips, showing assignment income, deductions like taxes and NICs, and net pay (take-home income).
  • The assignment rate includes gross pay, Employer’s NICs, holiday pay, apprenticeship levy, and the umbrella company’s margin.
  • Employer’s NICs (13.8%), apprenticeship levy (0.5%), and pension contributions are deducted from the assignment rate before calculating gross pay.
  • Gross pay is calculated after employment costs. Taxable income and take-home pay result from further deductions, including Income Tax and employee NICs.
  • PAYE is used for tax deductions based on HMRC’s brackets, with adjustments for earnings over ??100,000. Correct tax codes ensure accurate deductions.

Umbrella company payslips

Contractors are employees of their umbrella company and, as employees, should receive a payslip for every contractually agreed payment cycle. For both new and experienced contractors, understanding an umbrella company payslip may be challenging; it’s not easy to follow how pay has been calculated or what deductions have been made.

Your umbrella company payslip should include your personal details, including your name, employee number, National Insurance number and tax code. It will also list any deductions from your gross income, taxes (Income Tax and National Insurance Contributions), student loan payments, and pension contributions. Once these deductions have been calculated, you’ll be left with your net income, otherwise known as your “take-home pay”.

A contractor working through an umbrella company will also receive an invoice reconciliation alongside their payslip. The reconciliation breaks down the deductions from assignment income to determine the contractor’s gross pay. It is intended to ensure contractors have visibility of the invoices raised to the fee payer and the statutory and non-statutory deductions umbrella companies make.

To calculate an employee’s gross pay, umbrella companies deduct statutory employment costs and their margin from the assignment income (the amount the fee payer is invoiced). The employment costs include Employers’ National Insurance Contributions (NICs) and the??Apprenticeship Levy. Employer’s pension contributions are also deducted if applicable. Once these costs have been subtracted, you’re left with your gross pay.

The margin is the only deduction retained by the umbrella company; all other deductions are made on behalf of either HMRC or a pension provider.

Umbrella companies comparison sites

Before you choose which umbrella company to join for your contracting business, chances are you’ll seek out reviews online. Google makes it incredibly simple to find information relating to umbrella companies online; however, the integrity of such information is often questionable.

The past few years have seen a massive growth in umbrella comparison websites, sites asking you to enter your details and they’ll send you a personalised quote. While some of these sites may be legitimate, many are not. You’ll often find the top recommended slots on these comparison sites to be populated by the site’s sponsors. The umbrella companies willing to pay the most get recommended to contractors – hardly an impartial or fair review service!

Although there will always be scope for fake or manipulated reviews to be included, review websites like Trustpilot or Feefo can be used as valuable barometers to determine how particular umbrella companies treat their contractors. As long as you approach the reviews cautiously, these sites can provide indicators of the overall perception of a given umbrella company.

Reddit also has an active contractor community that can be called upon for advice regarding which umbrella company to use.

Best umbrella companies

The best umbrella companies will ensure the process of being paid is simple and stress-free. Good umbrella companies typically make a payment run every week (some make several per week), ensuring you’re paid reasonably soon after invoice submission.

Salary sacrifice pension contributions are essential for contractors to reduce their tax liability, especially those earning over ??100k. Not all umbrella companies offer salary sacrifice arrangements, and where they do, some charge additional fees for processing these payments.??It’s worth noting that these additional charges, assuming they’re not exorbitant, are usually reasonable given the extra administration involved for the umbrella company.

Furthermore, a reputable umbrella company should provide you with support and advice, promptly responding to emails or calls. Fully automated and online umbrella companies may be cheaper, but it is almost certain you will need to speak to a qualified person at some point during your contract.

The two most recommended umbrella companies on the Reddit forum are Paystream and NASA.

Worst umbrella companies

Some umbrella companies may try to entice you by suggesting they offer a more efficient payment structure. The most common methods are:

• Splitting your salary

Some umbrella companies may try to make their payment structures sound more efficient by splitting your salary into multiple payments, with only one portion going through PAYE and the rest paid as •loans,• •allowances,• or •grants.• This approach disguises part of your taxable income, reducing visible tax deductions, but HMRC treats such arrangements as disguised remuneration schemes. Even if the umbrella company claims compliance, you remain legally responsible for any unpaid tax, penalties, and interest if HMRC later deems it avoidance.

• Paying you via an offshore structure

Others may pay you through an offshore structure, routing income via a company based in a low-tax jurisdiction. While this may appear to reduce UK tax liability, anyone living and working in the UK must still pay tax on their worldwide income. Offshore payment schemes are considered non-compliant and have been heavily targeted by HMRC under rules like the Loan Charge, leaving many contractors with large retrospective tax bills and legal exposure.

• Paying you via a share ownership agreement

A third method involves payment through share ownership agreements, where part of your income is issued as ‘shares,• •units,• or •capital• in the umbrella company or an associated entity. These are often promoted as tax-efficient or as investment opportunities, but in most cases they are merely a way to disguise normal salary. HMRC can reclassify such payments as employment income, making full PAYE and National Insurance contributions due. This can also create financial complications, such as affecting your ability to prove earnings for loans or mortgages.

These schemes are tax avoidance or, at worst, tax evasion.

As an umbrella company employee, you should receive 100% of your income through PAYE. Working through an umbrella company offering anything else could expose you to backdated taxes, penalties, and late interest payments should HMRC catch you.

All umbrella companies are required to follow HMRC’s tax rules and regulations; there is almost no room to manage your tax liability advantageously once you enter PAYE. Take-home pay should never vary, regardless of the umbrella company chosen, and as such, it is difficult for one compliant umbrella company to be significantly better than another.

Contractors should also be wary of umbrella companies with entry fees, exit fees or penalties for leaving early. The company is your employer, so assuming you adhere to your terms of employment, it should not be charging you anything beyond the agreed margin.

Finally, you should avoid umbrella companies that link their margin to the contractor’s rate. A reputable umbrella will not charge you for what you earn; no additional work is involved from their perspective should your rate increase.

Payslip terminology

Important terminology that every umbrella company worker should be aware of:

Assignment Income

The assignment rate is the amount the umbrella company invoices the end client. It consists of employment costs, the umbrella company’s margin, and the actual wages payable to you (your gross pay).

Umbrella Margin

Margin is the technical term for the fee that umbrella companies charge contractors. It’s an administration fee (usually around ??25 per week), covering the costs of running the payroll, insurance for the contractor, and other operational expenses involved in running a business.

The margin is commonly charged to you as a fixed weekly amount, or in some cases, it is a percentage deduction with a maximum cap based on your weekly gross agency rate (although percentage margins are rare nowadays). For example, if you become an employee of an umbrella company with a ??22 per week margin, you will see a ??22 deduction on your weekly payslip.

Umbrella company margins only apply when you’re paid; if you are between contracts but remain on an umbrella company’s books, the company will not subject you to any costs.

Employer NIC’s

All UK employers, including umbrella companies, are required to make Employer’s National Insurance Contributions to HMRC. As the umbrella company employs contractors but receives no benefit from the work performed, the contributions are passed to the contractor. They are calculated as 13.8% of your earnings above the Lower Earnings Limit.

Apprenticeship Levy

The Apprenticeship Levy is a small tax levied on UK employers to fund new apprenticeships. All employers with annual pay bills of ??3m or more must pay the Levy at 0.5% of the company’s total wage bill, minus a fixed ??15,000 yearly allowance.

For contractors, your umbrella company is your employer, and it must, by law, pay all employment taxes based on income generated by its employees. Umbrella companies pay these statutory employment costs from the funds received from your agency or end client. As the apprenticeship levy is one of these statutory costs, it will appear on your payslip alongside other statutory costs, such as the Employer’s National Insurance.

Workplace Pension Contributions

As an employee of an umbrella company, you are eligible for a workplace pension. The minimum amount payable is 8% of your gross pay: 3% employer and 5% employee contributions. As employer contributions are deducted from the assignment rate, most contractors opt out of workplace pensions in favour of their salary sacrifice schemes.

Salary Sacrifice Pension Contributions

A salary sacrifice pension contribution is where an umbrella worker exchanges part of their gross income to receive contributions directly into their self-invested personal pension (SIPP). This deduction is made before PAYE and NICs, making it a hugely attractive option for contractors.

Basic (Statutory) Pay

As your employer, Umbrella companies must pay you a minimum wage. This ‘basic pay’ is calculated as the hours you have worked in each billing cycle multiplied by the National Minimum Wage.

Holiday Pay

Umbrella company employees are entitled to holiday pay, calculated as 12.07% of your gross income. It’s important to note that this is not an additional payment; the figure is incorporated into the assignment rate.

Commission

The final element in an umbrella company calculation is commission (or bonus). It is calculated as anything owed to the contractor above the basic pay and holiday pay, and acts as a balancing figure between these two pay elements and total taxable income.

Income Tax

Like permanent employees, umbrella companies pay the contractor’s wages via PAYE. The required tax and NICs are made at source and paid directly to HMRC.

Employee NICs

All employees must pay NICs on their taxable income, calculated as 12% of earnings above the primary threshold, up to and including the upper earnings limit, and 2% thereafter. It’s important to note that this is in addition to the Employer’s NICs already deducted from the assignment income.

Student Loan Repayments

If applicable, contractors employed by an umbrella company will make student loan repayments via PAYE. Umbrella companies will confirm directly with HMRC which repayment plan is applicable.

What are the different types of umbrella company pay?

The difference between an assignment rate, gross pay and taxable income is a common cause of confusion among workers new to umbrella employment. Contractors working Inside IR35 via an umbrella company are advised to understand the different types of pay quoted during negotiations, as the actual rate they receive could be less than expected.

1

Assignment rate

The assignment rate, sometimes called ‘umbrella income’ or ‘contract rate’, is the amount the umbrella company invoices the end client. It is calculated based on the number of hours worked by the contractor multiplied by the hourly rate agreed during contract negotiations.

The assignment rate is not the same as a PAYE salary-based rate and is not the amount the contractor receives. It includes employment costs, such as the Employer’s National Insurance, holiday pay, apprenticeship levy, employer’s pension contributions and the umbrella company’s margin.

2

Gross Pay

Gross pay, or gross income, refers to the total amount a contractor is owed before tax and any allowable deductions are removed. To calculate gross pay, umbrella companies deduct statutory and non-statutory employment costs from the assignment income (the amount the fee payer is invoiced).

These employment costs include: Employers’ National Insurance Contributions, the??apprenticeship levy, the umbrella company’s margin, and end employer’s workplace pension contributions (if applicable). Once these costs have been deducted, you’re left with your gross pay.

These employment costs are why rates for Inside IR35 roles are usually quoted higher than rates for Outside IR35 roles; they need to consider these deductions.

3

Taxable Income

To calculate taxable income (or •adjusted net income•), you start with gross pay and then subtract certain allowable deductions. These deductions are usually limited to pension contributions for contractors working via an umbrella company.

Once these allowances have been deducted, you’re left with the money you pay tax on.

4

Take Home Pay

Net pay, or ‘take-home-pay’, is the amount received after deducting all taxes from your taxable income. It is the amount paid to the contractor’s bank by the umbrella company.

You have the right to appeal HMRC’s decision, a process that involves a review of the case by an independent tribunal.

How do umbrella companies calculate tax?

Umbrella companies process two types of taxes: those for an employer and those for an individual.

Employer

Employer’s taxes include statutory contributions such as Employer’s National Insurance and the Apprenticeship Levy. These are costs that the umbrella company must pay to HMRC as part of employing you and are factored into the overall rate charged to the client.

Employer’s NI, for example, is currently 13.8% on earnings above the secondary threshold, and the Apprenticeship Levy adds a further 0.5%. These costs are not deductions from your gross pay but rather business expenses that the umbrella company accounts for when calculating your assignment rate. For more detail on these, refer to our Umbrella Companies and National Insurance guide.

Individual

Contractors working through an umbrella company will have their individual earnings processed through PAYE. HMRC determines PAYE calculations; umbrella companies have no say in the methodology and formulae used.

HMRC has four tax brackets based on total taxable income:

• Those with a taxable income below ??12,570 benefit from a tax exemption, otherwise known as the Personal Allowance.

• If your taxable income is between ??12,751 and ??50,270, you’re subject to the basic rate of 20%.

• If your taxable income is between ??50,271 to ??150,000, you’re in the higher-rate band, taxed at 40%.

• Finally, the Additional rate levies a tax rate of 45% for incomes above ??150,000

For many contractors, the ‘??100k abatement’ must be considered. For earnings over ??100k per annum, the tax-free personal allowance is reduced by ??1 for every ??2 over ??100k that is earned. This adjustment is made through the contractor’s tax code.

The tax code used to calculate your net pay will be the one supplied to the umbrella company on your P45, provided directly by HMRC via a P6 coding notice, or arrived at as the result of you completing a new starter checklist. If you believe your tax code is incorrect, you must contact HMRC to ask them to send an updated tax code to your umbrella company.

Tax Avoidance


Tax avoidance vehicles masquerading as umbrella schemes often try to target contractors, offering inflated take-home pay rates. The warning signs may be obvious to established contractors, but many have been duped into using them. These schemes do not work, and those who use them may have to pay much more than the tax they tried to avoid.

Key takeaways

  • Tax avoidance schemes manipulate tax rules through artificial transactions, often disguising payments like loans or grants as non-taxable to provide higher take-home pay.
  • Indicators include claims of retaining 80•90% of earnings, unusual payment arrangements (e.g., loans) and additional contracts beyond employment agreements.
  • Many schemes are based outside the UK in tax havens like the Isle of Man or Cayman Islands; UK taxpayers should prioritise UK-based umbrella companies.
  • HMRC frequently challenges tax avoidance schemes, leading to hefty penalties, legal costs, interest, and high-risk taxpayer designation for participants.
  • Legitimate umbrella companies operate strictly via PAYE and never promote tax avoidance arrangements, ensuring compliance with HMRC regulations.

What is a tax avoidance scheme?

A tax avoidance scheme operates with the intention of bending the rules of the tax system to gain an advantage that was never intended. They often involve contrived, artificial transactions that serve little or no purpose other than to produce this advantage.

For Inside IR35 contractors, these schemes involve an umbrella company giving you some or all your pay in the form of a loan, salary advance, grant, annuity or any other payment you’re told you’re not expected to pay back. These payments are claimed to be non-taxable, often without explanation, and can lead to higher take-home pay.

You may be asked to sign an agreement with an umbrella company in addition to your employment contract. This will often be a loan or other arrangement that attempts to disguise some of the payments paid to you by your umbrella company as non-taxable.

The untaxed amount may be diverted through a chain of companies, trusts or partnerships (often based offshore) and paid to you by a third party. In other cases, the payments may be made directly to you from a UK-based umbrella company.

It is worth noting that some tax avoidance schemes market themselves as being compliant umbrella companies. Compliant umbrella companies only operate via PAYE and never advertise or promote tax avoidance arrangements.

How to spot a tax avoidance scheme?

Here are some warning signs that you might be in a tax avoidance scheme or are being offered to join one:

• Higher Take-Home Pay

A contractor who operates through a legitimate and compliant umbrella company can expect to retain 60-70% of their salary after the relevant tax and National Insurance Contributions (NICs) have been made.

If a company claims you can retain up to 80% or 90% of your salary, it is most likely a tax avoidance scheme. Remember that the basic Income Tax rate is 20%, and you must also pay National Insurance Contributions.

• Unusual Pay Arrangements

Some schemes designed for contractors involve giving workers some or all of their payment either as a loan or other payment they’re not expected to repay. These schemes, promising to put tax-free income into a contractor’s pocket, do not follow HMRC’s prescribed rules.

• Signing Multiple Documents

Your umbrella company may ask you to sign another type of contract or agreement in addition to your employment contract. If they do, this can be a sign of a tax avoidance scheme.

• Misleading Claims

The scheme is advertised using misleading claims suggesting they are endorsed or approved by HMRC. These include: ‘HMRC approved’, ‘Retain more of your earnings after tax’, ‘We ensure you get the highest take-home pay’ or ‘Compliant tax efficient pay’. HMRC does not approve or endorse private limited companies.

• Based Outside The UK

Most tax avoidance schemes are located outside of the UK in well-known tax havens, including the Isle of Man, the Channel Islands, the Cayman Islands, East Asia, and South America. If you are a UK taxpayer, assuming your payroll provider should also be UK-based is sensible. An offshore address is a significant warning sign.

HMRC maintains a list of tax avoidance schemes , although they note that it is incomplete. If an umbrella company isn’t on the list, it doesn’t automatically make it safe to use. Contractors should always do their due diligence.

Tax avoidance penalties

Tax avoidance arrangements that claim you pay less tax are incredibly high risk. Most of these schemes do not work and have been successfully challenged by HMRC in the courts. If you’re involved in a tax avoidance scheme, HMRC will thoroughly investigate your tax affairs and may also require you to pay the tax you’re trying to avoid upfront.

You may receive a tax bill called an??accelerated payment notice, a requirement to pay the total amount of tax or National Insurance Contributions HMRC calculates as being due upfront and within 90 days.

If you do not pay the tax and National Insurance Contributions you owe, HMRC may decide to take legal action and take you to court. HMRC states that they win around 9 out of 10 avoidance cases heard in court. If you lose, you could face significant legal costs on top of the tax you owe, penalties and growing interest.

HMRC will treat you as a high-risk taxpayer; they will closely inspect all your tax affairs in future.

How to proceed

HMRC offer an interactive risk checker to help contractors working through umbrella companies identify if their employment arrangements could involve tax avoidance. If you’re still unsure, you should seek independent professional advice.

If you think you’re in a tax avoidance scheme, don’t wait for an investigation to catch you out. You should withdraw from the arrangement and settle your tax affairs with HMRC. The longer you put off settling and paying the tax due, the more interest you’ll pay, and the more you risk court proceedings.

HMRC has dedicated teams who can help you settle your affairs and won’t charge you for their advice.

Fees (Margin)


An umbrella company margin is the fees the umbrella company charges contractors for their payroll service. It is the only income the umbrella company receives as they do not directly benefit from the work performed by contractors. The margin covers the cost of running the contractor’s payroll, administration, internal staff salaries and other business costs.

The common questions we usually see are:

How do umbrella companies collect their fees?

Umbrella companies invoice the end client on behalf of the contractor, and the amount received is known as the ‘assignment income’. To calculate the contractor’s gross pay, umbrella companies deduct statutory and non-statutory employment costs from the assignment income. The umbrella company’s margin is one of these deductions.

There is no administration for the contractor, and they do not receive an invoice from the umbrella company. The fee deduction is made directly from the assignment income received from the end client.

Do umbrella companies charge VAT?

A contractor working via an umbrella company does not need to be concerned with VAT. The umbrella company itself should be VAT registered and will add VAT to the invoices issued to end clients. The umbrella company will then pass this VAT directly to HMRC. The contractor never sees VAT and is not impacted by it.

How much do umbrella companies charge?

The umbrella market is highly competitive, with most suppliers charging between ??25 and ??35 per week. Supplementary fees may be charged for services like salary sacrifice pension contributions as they are an additional administrative burden for the umbrella company.

Remember, lower prices don’t necessarily mean better. Fully automated and online umbrella companies may be cheaper, but it is almost certain you will need to speak to a qualified person at some point during your contract.

A reputable umbrella company should provide you with support and advice, promptly responding to emails or calls.

What are percentage fees?

In the past, some umbrella companies charged percentage fees, with the amount deducted being a proportion of the total amount billed to the client. This practice has largely stopped, and most umbrella companies will charge a fixed fee, regardless of your earnings. Any umbrella companies that charge a percentage fee should be avoided.

National Insurance


National Insurance Contributions (‘NICs’) are a tax on earnings paid by employees, employers and the self-employed. They help to build your entitlement to certain benefits, such as the State Pension and Maternity Allowance.

Key takeaways

  • As an umbrella company employee, you pay both Employee and Employer National Insurance Contributions.
  • Although umbrella companies act as the employer for payroll purposes, they do not benefit from work performed by the contractor.
  • As such, Employer NICs are ‘passed on’ to the contractor, being deducted from the assignment rate alongside other employment costs such as the Apprenticeship Levy.
  • These statutory deductions are mandatory, umbrella companies must process them on behalf of HMRC.
  • Umbrella companies do not profit from these deductions, they are passed directly to HMRC.

As an umbrella company employee, you’re subject to Class 1 NICs and liable for both the Employer’s and Employee’s payments owed to HMRC.

• Employee Contributions

Employee NICs are calculated at 8% of taxable income between the primary threshold of ??12,570 per year, the upper secondary threshold of ??50,270 per year, and 2% of any earnings above that. The employee’s NICs are paid directly to HMRC via the PAYE process; no administration is involved for the contractor.

• Employer Contributions

Employer NICs are calculated at 13.8% of taxable income above the secondary threshold of ??9,100 per year. The umbrella company will deduct the employer’s NICs from the contract assignment income, the amount invoiced and received from the end client.

Employer’s National Insurance

When a contractor signs up with an umbrella company, the umbrella company becomes the employer and the contractor the employee. In this relationship, the umbrella company provides a payroll service to the contractor; however, they don’t benefit from any work performed during the contract. As a result, umbrella companies are not in a position to cover the employer’s NICs.

The end client is the organisation benefiting from the work, although they are not technically the employer in this supply chain. Therefore, the employer’s NICs are passed on to the contractor.

There is a common misconception that umbrella companies are being unreasonable by passing these employment costs on; however, they have no choice. As contractors don’t work directly for the umbrella company, the umbrella company cannot afford to cover the required deductions.

It’s important to remember that your umbrella company is not retaining or profiting from these deductions; they are sent directly to HMRC. The margin charged covers the cost of processing payroll.

The Apprenticeship Levy

The Apprenticeship Levy is a small tax levied on UK employers to fund new apprenticeships. All employers with annual pay bills of ??3m or more must pay the Levy at 0.5% of the company’s total wage bill, minus a fixed ??15,000 yearly allowance.

For contractors, your umbrella company is your employer, and it must, by law, pay all employment taxes based on income generated by its employees. Umbrella companies pay these statutory employment costs from the funds received from your agency or end client. As the apprenticeship levy is one of these statutory costs, it will appear on your payslip alongside other statutory costs, such as the Employer’s National Insurance.

Employment costs, such as employer’s NICs and the Apprenticeship Levy, are why rates for Inside IR35 roles are usually higher than those for Outside IR35. End clients try to consider these deductions.

Holiday Pay


Contractors working through umbrella companies are employees and are therefore entitled to statutory holiday pay. In this relationship, the umbrella company provides a payroll service to the contractor; however, they don’t benefit from any work performed during the contract. As a result, umbrella companies cannot directly cover the holiday pay, which must come from the contractor’s earnings.

Key takeaways

  • On an umbrella payslip, the amount shown as holiday pay is a reallocation of earnings. Employment costs are deducted from the assignment rate to get gross pay, and 12.07% of this is considered holiday pay.

Do umbrella companies pay for holidays?

The short answer to this is, no! While contractors working through umbrella companies are entitled to holiday pay, the holiday pay isn’t paid out of the umbrella company’s own money. While the umbrella company manages the administration of apportioning holiday pay, the holiday pay itself is simply a reallocation of the contractor’s pay.

Similar to employment costs (employer’s NI, apprenticeship levy, etc.), holiday pay allocation is included within the assignment rate agreed upon with the fee-payer. Contractors will not receive an additional 12.07% uplift because the 12.07% is factored into the rate agreed upon during contract negotiations.

There are two methods by which umbrella company contractors can receive holiday pay:

• Accured

The umbrella company sets your holiday pay aside until you take annual leave (or the contract finishes). You will receive payment from your accrued holiday pot when you take time off.

• Advanced

The umbrella company adds holiday pay to your weekly (or monthly) payslip. It means you are always up-to-date with your holiday pay entitlement.

Contractors usually prefer the advanced payment method to avoid leaving money owed to you in an accrual account with the umbrella company. If the umbrella company were to go bust, the holiday pay would be lost.

How is holiday pay calculated?

The 12.07% allocated to holiday pay is based on the European Working Time regulations, which state that employees are entitled to 5.6 weeks of holiday in a year or 28 days. Dividing 5.6 by 46.4 (the remaining weeks in the year) gives a rounded figure of 12.07%.

The holiday pay figure shown on your payslip will be 12.07% * gross pay. To calculate gross pay, umbrella companies deduct statutory and non-statutory employment costs from the assignment income (the amount the fee payer is invoiced).

Holiday pay is a form of taxable income. It is, therefore, subject to statutory deductions such as Income Tax and NICs.

Expenses


While expenses can technically still be reimbursed while working through an umbrella company, you cannot offset them against your earnings like you can while working Outside IR35 through a limited company. Similar to permanent employees, all expense claims must be submitted, approved by the client, and paid in addition to your regular contract income.

Key takeaways

  • Umbrella company workers can only claim client-approved, billable expenses (like exceptional travel or overnight stays), which are reimbursed in addition to income. They cannot offset taxable earnings.

Example

No umbrella company can legally process anything other than client billable expenses for tax relief purposes. Any umbrella company that actively promotes otherwise should be avoided as they are almost certainly behaving unethically.

The easiest way to think about umbrella company expenses is to consider yourself a permanent employee of the end client. If a permanent employee can ask their employer to reimburse an expense, it is likely you can also. If they can’t, you can’t.

Let’s look at an example.

As an umbrella worker, travel to and from the end client’s regular place of business (i.e. ordinary commuting) is not an allowable expense. However, if you must travel away from the end client’s principal place of work, you can ask the client to reimburse the expenses incurred.

Any exceptional travel is permitted to be reimbursed as a tax-free expense, and the costs of accommodation, where you are required to stay overnight for work, are also allowable. This mirrors the treatment of permanent employees who can claim expenses when visiting clients or performing off-site work.

Remember, these expenses do not offset your income. They are approved by the client and repaid in addition to the standard contract rate.

Claiming expenses via self-assessment

It is worth noting that, in limited cases, if you do not have an agreement with the client to reimburse expenses, you may still be able to claim HMRC.

You can use a P87 form to submit a claim at any point in the tax year if the claim is less than ??2,500; otherwise, you must submit the claim via your self-assessment tax return. You must have paid tax in the year you’re claiming for, and the amount of tax relief you receive cannot be more than the amount of tax you paid in that year.

Expenses prior to 2016 and the SDC assessment

Prior to April 2016, contractors using umbrella companies could claim tax relief on travel and subsistence (T&S) expenses by treating multiple assignments as temporary workplaces under “overarching employment.” However, this relied on precise contractual terms to avoid HMRC challenges.

Restrictive legislation brought in in 2016 ended overarching employment, introducing Supervision, Direction, or Control (SDC) rules. Each assignment became a separate engagement, classifying many workplaces as permanent, disallowing T&S expense relief, and addressing perceived tax relief abuse.

When determining whether the restrictive 2016 legislation captures them, HMRC applies a strict SDC test. Unfortunately, HMRC believes those employed through intermediaries, such as umbrella companies, are automatically subject to SDC unless proven otherwise.

As HMRC’s default assumption is that umbrella company workers are subject to SDC, the onus is on the contractor to demonstrate otherwise. HMRC isn’t prescriptive on what evidence they would find persuasive in considering whether this test is met, although they have made it clear that signed statements aren’t sufficient.

Where it is considered that the legislation doesn’t apply because the SDC test is not met, and HMRC are involved in an enquiry, they’ll test evidence by examining relevant documents and gathering facts from all parties involved.

How is the SDC assessment made?

The umbrella company usually makes the assessment in the form of a questionnaire, combined with input from the end client (if required). Where an incorrect assessment is made, any additional taxes owed are the liability of the umbrella company unless they relied on fraudulent documents provided during the assessment process. In this case, the liability shifts to the person who provided the documents.

Where there is a determination that a role is Inside IR35, the view is that the contractor is automatically subject to SDC, even if the tests may show otherwise. This is why contractors working Inside IR35 via umbrella companies rarely claim anything other than client-billable expenses.

Pensions


Umbrella company pensions offer contractors three options: workplace pensions (auto-enrolment), salary sacrifice, and net pay contributions. While workplace pensions are mandatory with government-set contributions, salary sacrifice provides greater tax efficiency and control. Net pay contributions offer basic tax relief with potential for higher-rate rebates. Choose carefully to optimise tax savings and pension growth.

Key takeaways

  • Salary sacrifice pensions are usually the most tax-efficient option for umbrella company contractors, reducing both Income Tax and National Insurance.
  • Not all umbrella companies support salary sacrifice, with most charging extra for the additional administrative burden.

Workplace Pensions (Auto-Enrolment)

A workplace pension, also known as an auto-enrolment pension, is set up by an employer for its employees. Employees typically pay a percentage of their monthly salary into the scheme, with employers also contributing.

As your employer, umbrella companies must legally enrol you into a workplace pension. When you register with an umbrella company, they’ll send you information regarding pension auto-enrolment and their preferred pension provider. This is usually NEST, the Government’s workplace pension scheme.

The minimum contribution set by the Government that you can pay into your pension is 8%, split into 5% employee and 3% employer. It’s important to note that both the employee’s 5% and the employer’s 3% are deducted from assignment income. They are not an additional uplift, and the umbrella company does not contribute from its own funds.

Both employee and employer workplace pension contributions reduce taxable income, thereby reducing Income Tax owed. The employer element also reduces gross pay, thereby reducing both employer and employee National Insurance Contributions

However, no National Insurance relief is given on the employee element. This makes workplace pensions less tax-efficient than salary sacrifice.

In addition, workplace pension schemes often come with high charges. Take the Government’s scheme, NEST, as an example. They charge 1.8% on every contribution and a 0.3% annual management fee. While the 0.3% fee is broadly in line with the industry average, the 1.8% contribution fee is steep. Plenty of Target Retirement Funds charge nothing to contribute and lower ongoing costs. See Vanguard’s Target Retirement as an example.

The Vanguard Target Retirement merely illustrates the high fees charged by workplace pensions; it is not advice or a recommendation to invest.

Salary Sacrifice Pension

A self-invested pension plan (‘SIPP’) is a type of personal pension that allows you to manage your investments or pay a chosen financial adviser to support you. Most contractors opt out of workplace pensions in favour of salary sacrifice as it offers more control and greater tax relief.

Umbrella companies deduct salary sacrifice contributions from your gross pay; there is no additional burden for the contractor. Contributions also reduce both Income Tax and National Insurance, unlike a workplace pension, for which only the employer element reduces NI.

It is, therefore, the best option for those seeking to minimise their tax liabilities.

Not all umbrellas offer salary sacrifice due to the challenges of implementing it into their existing payroll software. If it interests you, always double-check before you register that your chosen provider can accommodate salary sacrifice. As this is an extra administrative burden for an umbrella company, it often comes with supplementary fees.

Contributions from net pay

Many contractors contribute to their SIPP from their net take-home pay; the income received after all taxes and contributions have been paid. If you contribute to a SIPP from your net take-home pay, you will receive an automatic basic rate tax relief (20%) upon contribution.

Your SIPP provider will obtain this 20% relief directly from HMRC; you don’t have to do anything. You can then apply for higher rate (40%) and additional rate (45%) tax relief via your self-assessment at the end of the year.

To give an example, if you are a higher rate taxpayer (40%) and contribute ??8,000, your pension provider will automatically claim ??2,000 for you and you’ll get a ??2,000 tax rebate. Your pension pot is ??10,000 at a net cost to you of ??6,000.

This is less tax efficient than contributing via salary sacrifice, as you can’t claim National Insurance back via a tax return.

Maternity Pay


As an umbrella company contractor, the Government considers you a full-time employee. You’re therefore entitled to the same benefits as a permanent employee, including statutory maternity pay (‘SMP’). You can claim SMP for up to 39 weeks, and the amount you’re entitled to is based on your earnings:

• First 6 weeks:

90% of your average weekly earnings.

• Following 33 weeks:

The lower of 90% of your average weekly earnings and ??172.48.

Average weekly earnings are calculated using an average of the eight weeks leading up to the 15th week before the baby is due. Your maternity will be paid through your umbrella company’s PAYE system, subject to Income Tax and NI deductions as usual.

To qualify for maternity pay under an umbrella company:

• You need to provide your umbrella company with a MAT B1 certificate or similar proof of pregnancy.

• You need to have been employed continuously by the umbrella company for at least 26 weeks up to the 15th week that the baby is due.

• Your average weekly earnings must be at least ??123.

If you meet these eligibility criteria, your maternity pay can start any time within 11 weeks of the due date.

Health and safety risk assessments

As employees of their umbrella companies, contractors are entitled to a range of rights while pregnant, including the requirement for employers to perform health and safety risk assessments during the pregnancy.

While this may have minimal impact for desk-based roles (e.g., software developers), it can significantly affect contractors in physically demanding or hazardous roles (e.g., drilling engineers). As soon as you tell the client you’re pregnant, health and safety regulations could prohibit you from working offshore.

Umbrella company paternity pay

Statutory paternity pay (‘SPP’) is calculated the same way as SMP, paid the same way, and is subject to the same taxes. The eligibility criteria are also the same. You can take up to 2 weeks’ leave, although it all needs to be taken in one go. The leave can start any time after the birth but must end within 56 days of the birth (or due date if the baby is early).

The Maternity Allowance

If you do not qualify for statutory maternity pay, you should consider the Maternity Allowance instead. Payment timings and amounts are similar to maternity pay; however, you do not need to be employed to qualify. You qualify for the Maternity Allowance if you’ve been registered as self-employed for at least 26 weeks in the 66 weeks before your baby is due.

Sick Pay


Sick pay refers to the financial support provided to employees who cannot work due to illness or injury. In traditional employment settings, sick pay is a standard benefit employers offer as part of the employment contract. However, the landscape is different for contractors and freelancers operating through umbrella companies.

Sick pay entitlements through umbrella companies are limited compared to traditional employment arrangements. Employees in permanent roles may receive enhanced sick pay benefits as part of their contract, providing a higher level of financial protection during illness.

As an umbrella company worker, you are an employee of your umbrella company, so statutory sick pay is available to you. Unlike traditional employer-employee relationships, no enhanced sick pay is available.

If you fall ill and cannot work, your only avenue is to claim the statutory sick pay allowance of ??109.40 per week, payable by your employer for up to 28 weeks.

To be eligible for statutory sick pay:

• You must have a contract with the umbrella company as proof of employment.

• You must have spent some time working under the contract with the umbrella company.

• You must have been sick for four or more consecutive days, including weekends.

• Your average weekly earnings must be at least ??123.

• You must inform your umbrella company about the illness within seven days, and the information provided must be error-free.

If you have been ill for longer than seven days, you must provide solid proof of your illness. Once 56 days pass since the initial sickness period ends, employees become eligible for another 28-week maximum sickness period.

Insurance

Contractor Sickness Cover is an accident and sickness insurance for limited company contractors. It means you aren’t left out of pocket if you suffer a disease, sickness, or bodily injury preventing you from working. Qdos have a policy starting from ??27 per month.

Umbrella Company Calculator


Our Umbrella Company Calculator can be found here.

What an Umbrella Company Calculator Does

An umbrella company calculator helps inside IR35 contractors understand their true take-home pay by breaking down every deduction applied when working through an umbrella company. Because umbrella workers are paid via PAYE, the calculator shows how the assignment rate is transformed into a taxable salary after employer costs and umbrella fees are taken into account. It provides a realistic estimate of what you will actually receive, giving contractors clarity before accepting a contract.

Contractors inside IR35 often face confusion about how their pay is calculated. They are taxed as employees but do not receive the same benefits as permanent staff. In many cases, the day rate must cover employer’s National Insurance, the apprenticeship levy and umbrella company costs, which reduces the amount available for their gross pay. A calculator helps contractors understand whether a proposed rate makes financial sense once all deductions are applied.

Pension planning and holiday pay

Pension contributions are an important part of optimising inside IR35 income. The calculator allows contractors to test different pension contribution levels and see how salary sacrifice affects taxable income. This makes it easier to plan contributions in a tax-efficient way and evaluate how pension savings impact take-home pay.

Holiday pay under an umbrella company can be confusing, as it is often rolled up into the rate and not paid separately. A calculator shows how holiday pay is allocated within gross income and how it affects net pay across different pay periods. This helps contractors prepare for variations in earnings caused by bank holidays or reduced working days.

How our calculator handles deductions

The umbrella company calculator shows the stages of deduction clearly. It first removes employer National Insurance and employment costs from the assignment rate. It then calculates employee National Insurance and PAYE tax using HMRC thresholds. Seeing this step-by-step breakdown helps contractors understand why take-home pay is lower than the headline day rate might suggest.

Comparing take-home with permanent employment

Many contractors use an umbrella company calculator to compare the financial value of an inside IR35 contract with a full-time job. Since inside IR35 contractors do not receive benefits such as employer pension contributions or paid time off, understanding the equivalent salary comparison is essential. Our calculator highlights whether a contract rate adequately compensates for the lack of benefits.

Contractors can use the calculator to test different day rates, working days and pension levels. This allows them to see whether the net pay from a contract meets their financial needs. It also provides insights that help with negotiating better terms or choosing between multiple offers.

Our umbrella company calculator helps contractors forecast yearly take-home pay, budget effectively and prepare for periods without work. This long-range visibility is valuable for financial planning, especially in contract-based roles where income may fluctuate throughout the year.
