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.

Let an accountant sign you up
They sign you up, set up the software and send each update, so nothing is missed. We will match you with up to 4 local Making Tax Digital accountants.

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
