United Kingdom: UK Self Assessment Payment Plans Revised, Cash Flow Concerns Persist

On 30 October 2026, the Chartered Institute of Taxation (CIOT) and its Low Incomes Tax Reform Group (LITRG) responded to the UK government’s decision not to mandate payment of Self Assessment tax liabilities through PAYE. While welcoming the avoidance of mandatory PAYE collection, the institutes highlighted that earlier and more frequent payment schedules under the revised ‘timely payment’ regime could strain taxpayer cash flow, particularly for those with volatile incomes. The reforms form part of the broader Making Tax Digital (MTD) evolution and were detailed in the Autumn Budget 2026 documentation.

Key Takeaways

  • Mandatory PAYE Collection Avoided: The government dropped proposals to require Self Assessment payments via PAYE coding, reducing administrative burden for employers and employees.
  • Cash Flow Pressure Intensifies: Accelerated payment timetables mean taxpayers must settle liabilities sooner, potentially causing liquidity issues for seasonal workers, gig economy participants, and small business owners.
  • Implementation Uncertainty Remains: Practical details on how the revised payment plans will operate alongside MTD for Income Tax (from April 2027) are still pending, creating planning challenges for advisers and taxpayers alike.
