Outside IR35 Audit Contract Jobs

Audit contractors deliver independent assurance over an organisation's controls, processes, and financial statements. The scope of contract audit work spans internal audit, IT audit, regulatory audit, and specialist assurance engagements. In practice, you may find yourself planning and executing audit programmes, testing controls against regulatory requirements, reviewing IT general controls and application controls, assessing compliance with internal policies, drafting audit reports, and presenting findings to audit committees. Organisations hire audit contractors to supplement their internal audit teams during peak periods, bring in specialist skills for technology or regulatory audits, or provide independent assurance on specific transformation programmes.

The UK audit contracting market is steady and somewhat counter-cyclical: when the economy is uncertain and regulators are active, audit demand increases rather than decreases. Financial services firms are the largest hirers, driven by PRA and FCA expectations around independent assurance and the three lines of defence model. Government departments and NHS trusts also engage audit contractors, often through framework agreements. IT audit has become an increasingly large segment of the market as organisations digitise and regulators expect assurance over technology controls. Contractors with qualifications such as ACA, ACCA, CISA, or CIA are preferred, and those with experience in regulated sectors command higher rates. The market is less volatile than many contracting disciplines because audit obligations are ongoing and non-discretionary.

IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.

Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.

On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.

Audit contracts can sit outside IR35 when structured around the delivery of a specific audit engagement with a defined scope, timeline, and report as the output. Conducting an independent review of a particular control environment, delivering an IT audit report, or assessing compliance with a specific regulation are all engagements that lend themselves to outside IR35. The inherent independence required of audit work actually supports an outside IR35 determination, since the auditor must exercise professional judgement free from direction. Consultancies and mid-market firms are more likely to offer outside IR35 audit work than large banks.

Contract rates for audit roles typically range from £350 to £650 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement.
