Overview of Compliance Risks in 2026
Freelancers and contractors in the UK must pay close attention to enforcement changes coming through consultations in the Tax Update 2026 package, especially regarding HMRC’s information powers and new penalties.(gov.uk)
Key measures under review include:
- Reforms to Schedule 36 of Finance Act 2008, which defines HMRC’s powers to inspect records and obtain information. The consultation aims to modernise definitions (including computer records), ensuring HMRC has access to digital materials.(gov.uk)
- A proposed criminal offence for making reckless untrue declarations or false statements in direct tax. This marks a significant escalation from civil penalties.(gov.uk)
Implications for IR35 and Contractors
Contract assessments and record creation
Under the IR35 rules, whether someone is inside or outside involves evaluating:
- Whether substitution is allowed
- Who controls how, when and where work is done
- Whether there is mutuality of obligation
As HMRC increases power over inspection and record access, freelancers must maintain clear, contemporaneous evidence — written agreements, invoices, timesheets — to support their status.
Consequence of mis-classification
- Being inside IR35 means you must pay both income tax and employee’s National Insurance on payments, reducing net take home substantially.
- If HMRC pursues cases involving reckless false statements, the financial and reputational costs may be severe. Civil penalties are already substantial; criminal penalties escalate risk significantly.
Actionable Steps for Compliance
- Review all contracts: Ensure they clearly delineate contractor status (substitution, control, mutuality) with written agreements.
- Maintain strong records: Timesheets, emails, invoices, communications. Digital records are especially important.
- Seek expert advice: For complex arrangements, consider obtaining opinions or assurance from employment law lawyers or tax professionals.
- Monitor legislation and consultations: The consultations on HMRC’s powers are still open. Feedback and stakeholder views may alter final form.(gov.uk)
Example Scenario
David, a freelance software developer, has been working under contracts labeled “outside IR35”. He has no right of substitution and is told when and where to work, from 9-5. He’s currently using older email chains and verbal commitments to defend status. With new inspection powers, HMRC could demand full digital records; David should formalise substitution clauses, align control terms, and store records systematically (e.g. digital folders, encrypted backups).
Tips to Mitigate Risk
- Use Day-rate or Project-rate contracts with explicit substitution rights.
- Limit reporting ambiguity: document your actual working practice matches what’s in the contract.
- Cross-reference your status with HMRC’s CEST (Check Employment Status for Tax) tool — though not definitive, helps assess risk.
- Regularly review accounts and seek pre-emptive rulings where available.
Conclusion
Changes to HMRC’s compliance powers and new criminal penalties mean higher stakes for contractors under IR35. By tightening contracts, preserving all records, and staying current with policy changes, freelancers can reduce risk and ensure they’re treating IR35 status honestly and defensibly.
