About Our Inside IR35 Audit Contract Roles
What does a audit contractor do?
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.
What is the market like for audit contractors?
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.
What does Inside IR35 mean?
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 inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.
Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
On QualityContracts.co.uk, approximately 49% of roles with a stated IR35 status are classified as inside IR35, making it the most common arrangement across the contract market. The proportion varies by sector and role type. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What audit roles are usually Inside IR35?
Inside IR35 audit work is common in organisations with large internal audit functions where contractors are embedded alongside permanent auditors. Banks, insurers, and government departments frequently engage audit contractors inside IR35 to execute audits planned by the Head of Internal Audit. The contractor follows the organisation's audit methodology, uses its tools and templates, and reports through its management structure. This level of integration typically supports an inside IR35 determination. IT audit contractors working inside IR35 should negotiate rates that reflect the premium for combined technology and audit expertise.
How much do audit contractors usually earn when working Inside IR35?
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. Inside IR35 rates are typically 15% to 30% higher than equivalent outside IR35 roles to account for tax and national insurance deducted at source by the fee-payer.
