New services for Self Assessment tax customers

HM Revenue & Customs (HMRC) is introducing new services to improve Self Assessment registration, manage processes, and appeal penalties.

People who pay their tax through Self Assessment are to benefit from new services, making the process simpler and easier.

New Self Assessment services

HMRC has set out a series of measures, as part of its Transformation Roadmap, to support customers when they interact with the department. These include:

• improvements to the digital Self Assessment registration and opt-out processes
• introducing enhanced on-screen messages to reassure customers and reduce the need for them to chase progress on enquiries
• and improving the late filing and late payment penalties online appeals process

Read further details on the new services announced for Self Assessment customers as payment deadline approaches.

Benefit by filing your tax return early

HMRC is encouraging customers to get ahead this summer by filing their Self Assessment tax return for the 2024 to 2025 tax year early, such as at the same time as settling their Payment on Account, and exploring flexible payment options ahead of the 31 January 2026 deadline.

If customers file early, they will know how much tax they owe and may be able to reduce their next Payment on Account if their income has decreased. It also means that if a refund is due, it can be received sooner.
