Understanding the HMRC investigation landscape for contractors
As an HR contractor, the prospect of an HMRC tax investigation can feel overwhelming, but understanding why they occur is the first step in preparation. HMRC typically targets contractors when they identify discrepancies in tax returns, suspect disguised employment through IR35, notice inconsistent income patterns, or receive third-party information suggesting non-compliance. The 2024/25 tax year brings increased scrutiny on the contracting sector, particularly around IR35 compliance and expense claims. Knowing how should HR contractors prepare for a tax investigation begins with recognizing these risk areas and maintaining impeccable records from day one.

HMRC can investigate returns up to four years back for careless errors, six years for inadequate records, and up to twenty years for deliberate tax evasion. With investigation costs potentially running into thousands of pounds even for compliant contractors, proactive preparation isn't just prudent—it's essential business practice. This is where understanding how should HR contractors prepare for a tax investigation becomes a critical component of your business resilience strategy.

When considering how should HR contractors prepare for a tax investigation, documentation is your first line of defense. HMRC expects comprehensive records covering all aspects of your business operations. Essential documents include contracts demonstrating genuine self-employment, detailed invoices and payment records, business expense receipts with clear business purposes, bank statements reconciling all transactions, and correspondence with clients and agencies. For IR35 purposes, you'll need contracts, working practices evidence, and substitution right documentation if applicable.
Digital record-keeping has transformed how contractors manage their documentation. Using specialized tax planning software ensures your records are organized, searchable, and readily available when needed. This approach addresses the core question of how should HR contractors prepare for a tax investigation by creating an audit trail that demonstrates professionalism and compliance. Maintain records for at least six years, as HMRC can investigate this far back if they suspect inadequate record-keeping.

For HR contractors operating through limited companies, maintaining evidence of genuine self-employment is crucial—this includes right of substitution, control over work methods, and financial risk evidence.
Status Determination Statements (SDS) from clients in the public sector or medium/large private sector companies provide crucial evidence. Keep these documents alongside contracts and working practices evidence. If you determine your own status for small private sector clients, document your assessment process thoroughly. Regular reviews of your IR35 status, especially when contract terms change, demonstrate ongoing compliance and form an essential part of how should HR contractors prepare for a tax investigation scenario.
