A practical guide for sole traders and landlords approaching £30,000 in income.
Making Tax Digital for Income Tax is a legal requirement to keep digital business records and send HMRC a short online update every three months, rather than relying on one Self Assessment return a year. It has applied since 6 April 2026 to sole traders and landlords with qualifying income over £50,000, and from 6 April 2027 it extends to anyone with combined self-employment and property income over £30,000.
For those newly affected, the change is less about the tax owed and more about how records are kept. Four quarterly updates are followed by a year-end final declaration – similar in substance to the annual tax return many people are used to, but sent through compatible software rather than HMRC’s own online service. A shoebox of receipts sorted once a year is no longer enough.
More than 436,000 sole traders and landlords successfully sent their first Making Tax Digital for Income Tax quarterly update, and over 570,000 had signed up to the service, HMRC confirmed as at 12 August 2026. The next wave is expected to be considerably larger.
If your combined income from self-employment and property sits between £30,000 and £50,000, your 2025/26 tax return is the one HMRC will use to decide whether you join from 6 April 2027, so the time to prepare is now rather than next spring.
Key takeaways
- Threshold: Combined self-employment and property income over £30,000 – on a gross basis, before any expenses are deducted – means joining Making Tax Digital for Income Tax from 6 April 2027, based on your 2025/26 tax return.
- Reporting: Four quarterly updates plus a final declaration submitted through compatible software.
- Joint property: Only your own share of jointly owned rental income counts towards your qualifying income, not the total.
- Penalties: Unlike the first intake in 2026, there is no penalty-free grace year for quarterly updates in 2027 – points-based fines can apply from day one.
- Scope: Partnerships and limited companies are not yet included, and qualifying income of £20,000 or less remains automatically exempt.
What is Making Tax Digital for Income Tax?
Making Tax Digital for Income Tax is HMRC’s system for reporting self-employment and property income digitally throughout the year, alongside your annual final declaration. It does not create a new tax – Income Tax, Class 4 National Insurance and the underlying rules for calculating profit all stay the same. What changes is the reporting process.
Anyone within scope must keep digital records of self-employment and property income and expenses, send HMRC a quarterly update every three months, and submit a year-end final declaration by 31 January, through compatible software rather than HMRC’s own online service. You cannot submit your final declaration for the year until all four quarterly updates have been sent.
The rules apply in the same way across England, Scotland, Wales and Northern Ireland. Scottish taxpayers pay Income Tax at different rates and bands, but that affects how much tax is due, not whether the rules apply.
The three thresholds, and when they come into effect
Making Tax Digital for Income Tax is being introduced in three stages, based on qualifying income – broadly, gross self-employment and property income before expenses – declared on a specific year’s tax return.
| Qualifying income over | Tax year | Mandatory from |
| £50,000 | 2024/25 | 6 April 2026 |
| £30,000 | 2025/26 | 6 April 2027 |
| £20,000 | 2026/27 | 6 April 2028 |
HMRC reviews the relevant Self Assessment return each year and writes to anyone who has crossed a threshold, confirming they need to join from the following April. That letter is a courtesy rather than a condition – responsibility for checking your own position sits with you even if none arrives.
For the £30,000 threshold, your 2025/26 tax return, due by 31 January 2027, is the one that counts. Because that return covers income already earned, some people only discover they are affected weeks before the new rules start – working out your likely position now gives you far more useful notice.
What counts as qualifying income?
Qualifying income is your total turnover from self-employment and property, added together, before any expenses are deducted. It is based on the tax return you submit for the relevant year, not on profit.
Suppose you earn £22,000 from self-employment as a personal trainer and receive £9,500 in gross rent from a buy-to-let flat you own outright. Your combined qualifying income is £31,500, just over the £30,000 threshold, so you would need to start using Making Tax Digital for Income Tax from 6 April 2027, based on income declared on your 2025/26 tax return.
Some income is excluded from the calculation altogether. Employment income taxed under PAYE, dividends, State Pension and private pensions, and your share of profit from a partnership as an individual partner, do not count towards qualifying income, even though they still need to be reported on your tax return.
