HMRC Updates Off-Payroll Working Rules for 2026-27

HMRC has published updated guidance on the off-payroll working rules (IR35) for the 2026-27 tax year. The changes are designed to improve compliance and provide greater clarity for umbrella companies, recruitment agencies, and end-hirers.

Key Changes

• Enhanced status determination: End-hirers must now provide more detailed reasoning when issuing Status Determination Statements (SDS), including specific reference to the CEST tool factors considered.
• Record-keeping requirements: All parties in the labour supply chain must retain IR35 determination records for a minimum of 6 years, up from the previous 3-year requirement.
• Dispute resolution timeline: The deadline for responding to status disagreements has been reduced from 45 to 30 calendar days.
• Penalty framework: HMRC has introduced graduated penalties for non-compliance, ranging from warnings for first-time minor breaches to significant financial penalties for repeated failures.

Impact on Umbrella Companies

For umbrella companies, the most significant change is the enhanced due diligence requirement when accepting workers from agencies. Umbrella companies must now verify that a valid SDS has been issued and retain copies as part of their compliance documentation.

PaySentry’s platform automatically tracks SDS documentation and flags missing or expired determinations, helping umbrella companies maintain compliance with the new requirements.

What You Need to Do

We recommend all umbrella companies review their current IR35 processes and ensure their systems can accommodate the new record-keeping requirements before April 2027.
