Add up your self-employment turnover and your rental income for the year, before any expenses. If it was over £30,000 on your 2025–26 tax return, you'll need to use Making Tax Digital from 6 April 2027. If it was over £50,000 on your 2024–25 return, you should already have started in April 2026. Over £20,000 on your 2026–27 return means you start in April 2028.
The thresholds and dates
HMRC decides using the tax return from two years before your start date:
| Qualifying income | On your return for | You start from |
|---|---|---|
| Over £50,000 | 2024–25 | 6 April 2026 |
| Over £30,000 | 2025–26 | 6 April 2027 |
| Over £20,000 | 2026–27 | 6 April 2028 |
HMRC checks your return every year in the same way. If you're under the threshold now but go over it later, the return for that year decides when you join: for example, over £20,000 on your 2027–28 return means you start in April 2029.
What counts as qualifying income
Qualifying income is your gross income from these sources, before any expenses are taken off:
- turnover from all your self-employments added together
- rent and other income from UK and overseas property
These don't count:
- wages from a job taxed through PAYE
- your share of profits from a partnership
- State Pension and private pensions
- savings interest and dividends
So someone earning £45,000 from a job and £18,000 in rent has qualifying income of £18,000, and doesn't need to join until the £20,000 threshold, if at all.
Jointly owned property
If you own property with someone else, only your share of the rent counts. A house let for £50,000 a year and owned 50/50 gives each owner £25,000 of qualifying income from it.
Some examples
| Who | Qualifying income | Starts |
|---|---|---|
| Electrician: £38,000 of sales, £14,000 of costs | £38,000 | April 2027 |
| Landlord: two flats, £2,700 a month in total | £32,400 | April 2027 |
| Hairdresser £19,000 sales, plus £13,000 rent from a flat | £32,000 | April 2027 |
| Nurse on PAYE, plus half of £16,000 rent from a house owned with a sibling | £8,000 | Not yet |
Each example assumes the same income on the return HMRC looks at.
Who is exempt
Some people don't have to use Making Tax Digital, either for now or for good. You're automatically exempt, without applying, if:
- you didn't have a National Insurance number before the tax year started
- you're a trustee, or a personal representative dealing with someone's estate
- you get, or transferred, Married Couple's Allowance or Blind Person's Allowance
Some people are deferred until at least April 2027, again without applying. This includes people whose return:
- claims averaging relief (for example farmers, and creators of literary or artistic work)
- claims qualifying care relief (foster and kinship carers)
- includes income from trusts and estates, or the residence pages (including people not resident in the UK)
You can apply for an exemption if you're digitally excluded: your age, health or disability means you can't use digital devices, or your religious beliefs are incompatible with using them. You apply to HMRC by phone or in writing.
Partnerships aren't included yet. HMRC says they'll need to join in future, but hasn't set a date.
Volunteering early
You can sign up before you have to, for the current or next tax year. It's a way to get used to quarterly updates before they're compulsory. See How to get ready for Making Tax Digital.
If your income goes down
Once you've joined, you stay in even if your income drops below the threshold for a year. You can leave once your qualifying income has been under the threshold for three tax years in a row.
