How to sign up for Making Tax Digital
If you fall within the income thresholds for Making Tax Digital (MTD) for Income Tax, you will need to register with HMRC before you begin submitting quarterly updates.
Registration is not automatic. Even if HMRC notifies you that you are required to comply, you or your authorised agent must complete the sign-up process.
Step 1: Check that you are required to register
Before signing up, confirm that your qualifying income exceeds the relevant threshold:
- Over £50,000 from April 2026
- Over £30,000 from April 2027
Qualifying income includes gross self-employment and rental income.
If you are unsure whether you meet the threshold, review your most recent Self Assessment return or speak to your accountant.
Step 2: Ensure you are using MTD compatible software
You must have compatible software in place before registering.
This software must allow you to:
- Keep digital records
- Submit quarterly updates
- Submit your final declaration
HMRC provides a list of recognised MTD compatible software options on its website.
You cannot submit MTD updates through the existing Self Assessment online portal.
Step 3: Register with HMRC
Registration is completed through HMRC’s online service.
You will need:
- Your Government Gateway account
- Your Unique Taxpayer Reference
- Details of your accounting period
If you use an accountant, they can register you as your authorised agent.
Once registered, you will receive confirmation from HMRC that you are signed up for MTD.
Step 4: Begin quarterly reporting
After registration, you must submit quarterly updates through your chosen software.
For most individuals, the standard tax year quarters run as follows:
- 6 April to 5 July
- 6 July to 5 October
- 6 October to 5 January
- 6 January to 5 April
Each quarterly update must be submitted by the 7th day of the month following the end of the quarter.
For example:
- Quarter ending 5 July must be submitted by 7 August
- Quarter ending 5 October must be submitted by 7 November
- Quarter ending 5 January must be submitted by 7 February
- Quarter ending 5 April must be submitted by 7 May
These are submission deadlines, not tax payment deadlines.
It is important to register in good time before your first quarterly deadline to avoid compliance issues.
Should I register early?
You do not need to register before your mandatory start date.
However, preparing early is sensible. This allows you to:
- Choose appropriate software
- Set up digital record keeping
- Understand your reporting responsibilities
Leaving registration too late increases the risk of errors or missed submissions.
Can my accountant handle registration?
Yes.
An authorised accountant can manage the registration process and ongoing submissions on your behalf.
Many individuals prefer professional oversight to ensure compliance is handled correctly from the outset.
Final thoughts
Signing up for Making Tax Digital involves more than simply registering with HMRC. You must also ensure your digital records and software are properly set up before quarterly reporting begins.
If your qualifying income exceeds £50,000 from April 2026, or £30,000 from April 2027, you will need to register and begin quarterly reporting from the relevant start date.
Preparing in advance allows you to transition smoothly and avoid unnecessary pressure.
