For the 2026/27 tax year, MTD for Income Tax generally applies to sole traders and landlords whose qualifying income in 2024/25 was more than £50,000, subject to exemptions. The reference year matters. Your profit today or your bank balance is not the test.

See the end of year Self Assessment report or explore quarterly reports.

Start with the correct tax year

Each threshold means more than the stated amount. Exactly £50,000 does not trigger the 2026 start date under this test. Check the full HMRC rules if your return, income sources or circumstances need correcting.

What qualifying income includes

It broadly combines self-employment and property income before expenses. Employment earnings, pensions and dividends do not form part of this threshold, although they can still matter to the annual tax return. UK residence, foreign income and jointly owned property can need special consideration; check HMRC’s qualifying-income guidance.

How combined income can change the answer

If 2024/25 qualifying self-employment income is £32,000 and qualifying property income is £21,000, the combined figure is £53,000. Subject to the other rules and exemptions, that points to a 6 April 2026 start. You do not assess each business separately against £50,000.

Likewise, £60,000 turnover and £25,000 allowable costs gives £35,000 starting profit, but the £60,000 gross figure is relevant to the qualifying-income test.

What if I started trading recently?

Starting a business does not automatically put you into MTD on day one. The reference-year return and HMRC’s rules determine your position. Someone with no earlier qualifying income may have a later start, while a new trade added to existing property or self-employment can need a different assessment. Read MTD for new sole traders.

Check exemptions before deciding

There are automatic and application-based exemptions, including digital-exclusion provisions. Do not assume being uncomfortable with software is enough, or that a missing letter means you are exempt. Follow HMRC’s eligibility and exemption links and use our MTD checker as an initial guide.

What to do if you are within scope

Check your HMRC registration status and choose suitable software. HMRC began signing up mandatory 2026/27 users who had not enrolled themselves from September 2026. If HMRC has enrolled you, check its instructions and income-source details; if it has not, sign up yourself or through an agent. Registration does not connect software or send updates for you. Use our registration walkthrough.

Quarterly updates are cumulative summaries for the tax year so far. Standard deadlines are 7 August, 7 November, 7 February and 7 May. They are not four full tax returns. After the year ends, review adjustments and other income and complete the annual return through suitable software. The 2026/27 annual return is normally due by 31 January 2028; a separate 2025/26 online Self Assessment return is normally due by 31 January 2027.

Records, software and costs

Keep the required digital records and supporting evidence. You may use a suitable spreadsheet-and-bridge arrangement rather than a large accounting package, but the complete process must meet the requirements. Compare bridging options and the complete MTD guide.

TaxSnapper is designed for straightforward UK sole traders to record income and expenses, store receipt photos and export quarterly reports and an end of year Self Assessment report. It does not submit MTD updates or tax returns to HMRC. Check import formats, required digital links and the annual-return coverage of separate submission software or an accountant before relying on any combination of products.

What happens if you are behind?

There are no penalty points for late quarterly updates for 2026/27, but updates are still required before the annual return can be submitted. Annual-return and payment obligations remain. Later-year points rules and separate payment rules need checking in our MTD penalties guide.

Bring the records up to date, check the deadline calendar and arrange the outstanding submissions. If unsure about your income or start date, get the position checked rather than guessing.
