What You Need Before You Register for MTD
Before you can register for Making Tax Digital for Income Tax, you will need: a Government Gateway user ID and password, your Unique Taxpayer Reference (UTR), your National Insurance number, compatible MTD software already set up, and details of your qualifying income sources.
How to Register for Making Tax Digital
The MTD registration process is completed through your HMRC online account. You authorise your compatible software to connect to HMRC, confirm your income sources and select your MTD start date. Mistakes at this stage can cause submission errors, so it is worth getting the process right first time.
What Happens After MTD Registration
Once registered, your software will be authorised to submit quarterly updates and your final declaration to HMRC. Your first quarterly update deadline will depend on your MTD start date. For those starting in April 2026, the first update is due by 7 August 2026.
