About Our Outside IR35 Tax Contract Roles
What does a tax contractor do?
Tax contracting covers the full range of corporate and indirect tax disciplines, from corporation tax compliance and transfer pricing through to VAT advisory, employment tax, and tax technology implementation. Organisations hire tax contractors to manage filing deadlines, respond to HMRC enquiries, implement tax provisions in ERP systems, advise on the tax implications of corporate transactions, and overhaul tax processes as part of finance transformation programmes. The work requires deep technical knowledge of UK tax legislation combined with practical experience of how tax obligations are managed within corporate environments. Tax contracting is distinct from tax advisory in professional services: as a contractor, you are typically embedded in the client's tax team rather than advising from the outside.
What is the market like for tax contractors?
The UK tax contracting market is relatively small but well-compensated, driven by the complexity of the UK tax code and the chronic difficulty organisations face in recruiting permanent tax professionals. Large corporates with multi-entity structures, international groups with UK operations, and private equity-backed businesses undergoing restructuring are the primary hirers. Demand peaks around filing deadlines and following major legislative changes, but a baseline of activity persists year-round. Transfer pricing and tax technology have emerged as growth areas within the market, with organisations investing in systems and processes to meet HMRC's Making Tax Digital requirements and OECD BEPS guidelines. Contractors with CTA or ATT qualifications alongside practical in-house experience are strongly preferred.
What does Outside 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 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.
What tax roles are usually Outside IR35?
Tax contracts can sit outside IR35 when structured around specific deliverables such as preparing a tax provision, conducting a transfer pricing study, or delivering a tax due diligence report for a transaction. Advisory-style engagements where the contractor provides expert analysis and recommendations are well suited to outside IR35. The technical nature of tax work and the professional judgement required support arguments for contractor autonomy. Smaller companies and private equity portfolio companies are more likely to offer outside IR35 tax work than FTSE 100 organisations.
How much do tax contractors usually earn when working Outside IR35?
Contract rates for tax roles typically range from £400 to £700 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement. Rates shown are for outside IR35 engagements and reflect the gross day rate paid to the contractor's limited company before any personal tax obligations.
