On 23 October 2026, HM Revenue & Customs (HMRC) issued a press release reminding Self Assessment customers that they have exactly 100 days remaining to file their tax returns for the 2025 to 2026 tax year and pay any tax owed. The deadline for online submission and payment is 31 January 2027. This annual reminder aims to encourage early filing to avoid last-minute congestion and potential penalties. The 2025-26 tax year covers income from 6 April 2025 to 5 April 2026. Taxpayers who have not yet registered for Self Assessment must do so by 5 October 2026 to receive their Unique Taxpayer Reference (UTR) in time.
Key Takeaways
- Filing Deadline and Penalties: The online filing deadline is 31 January 2027. Late filing incurs an automatic £100 penalty, with additional daily penalties after three months and further charges at six and twelve months. Interest accrues on unpaid tax from 1 February 2027.
- Payment Obligations: Any tax due for 2025-26 must be paid by 31 January 2027, along with the first payment on account for 2026-27. Taxpayers can pay via HMRC online services, the HMRC app, or bank transfer.
- Digital Support and Avoiding Errors: HMRC urges use of the HMRC app and online services for faster processing. The “Don’t Get Caught Out” campaign warns against misleading tax advice from unqualified agents.
