Before you start

What you need to sign up

  • Your Self Assessment user ID and password, the same ones you use to file your return
  • Your business start date, or when your property income started, if it was in the last 2 tax years
  • The tax year you will start using the service
  • For sole traders: your business name, address and trade
  • Details of each business, as HMRC asks you to check every self-employment and property business

Two routes

Signing up yourself or through an accountant

  • YourselfUse the online sign-up service on GOV.UK with your Self Assessment login, then choose your software.
  • Through an accountantAuthorise them as your agent and they sign you up through their own route, then send your updates.

If you plan to use an accountant, it is easier to choose one first and let them sign you up, so the software and permissions are set up together.

Timing

When to sign up

If your qualifying income was over £50,000 on your 2024 to 2025 return, you should already be signed up. Since September 2026, HMRC has been signing up people in that group who had not done it, using the information it holds. If that happens to you, HMRC will tell you what to do next, including any updates you have missed.

If you join on 6 April 2027, you can sign up now as a volunteer. That gives you time to get used to the software before the deadlines count. If you sign up part-way through a year, you need to send any missed updates for the year so far.

After signing up

What happens next

You keep digital records from your start date, send the quarterly updates by 7 August, 7 November, 7 February and 7 May, and file your tax return through your software by 31 January. Sole traders and landlords each have their own guide.
