Making Tax Digital Is Live: What Self-Employed People and Landlords Need to Do in 2026/27
Making Tax Digital Is Live: What Self-Employed People and Landlords Need to Do in 2026/27
The first mandatory MTD for Income Tax cohort is already inside the 2026/27 regime. The real change is not four extra tax returns; it is the move from annual reconstruction to continuous digital records.
Making Tax Digital for Income Tax is no longer a future reform. For the first mandatory cohort, it is now part of the 2026/27 tax year. That changes the operating model for self-employed people and landlords: records need to be digital, quarterly updates need to be sent through compatible software, and the annual tax return now sits at the end of a digital process rather than being the only formal interaction with HMRC.
The threshold is based on qualifying income, not profit
The first question is not “how much profit did I make?” but “what was my qualifying income?” HMRC’s current staged timetable brings people into MTD for Income Tax according to gross qualifying income from self-employment and property before expenses. Those with more than £50,000 for 2024/25 should have started from 6 April 2026. The next cohort, with more than £30,000 for 2025/26, enters from 6 April 2027, followed by more than £20,000 for 2026/27 from April 2028.
| Tax return used to test income | Qualifying income | MTD start |
|---|---|---|
| 2024/25 | More than £50,000 | 6 April 2026 |
| 2025/26 | More than £30,000 | 6 April 2027 |
| 2026/27 | More than £20,000 | 6 April 2028 |
This distinction matters because a business with £58,000 of turnover and £25,000 of expenses may still fall inside the first cohort even though taxable profit is much lower. It also matters for people with both property and self-employment income because qualifying income can combine the relevant gross amounts.
Quarterly updates are not four mini tax returns
One of the most common misconceptions is that MTD creates four full tax returns. It does not. Quarterly updates are summaries of digital records. Their purpose is to move reporting closer to the point at which the underlying business activity happens. The real burden therefore moves upstream: transactions must be captured, classified and corrected in compatible software.
For standard update periods, the first-year quarterly deadlines are 7 August, 7 November, 7 February and 7 May. That rhythm has a practical consequence. If bank feeds are unreconciled, personal transactions are mixed with business spending, invoices are missing or property costs are coded inconsistently, those weaknesses surface repeatedly rather than once at year end.
What a strong 2026 MTD workflow looks like
Use a dedicated business bank account where practical and avoid mixing personal spending with business transactions. The cleaner the source data, the easier the digital record becomes.
Invoices, expenses and supporting documents should be recorded close to the transaction date rather than reconstructed months later.
Digital does not mean accurate. Bank feeds still need review, duplicates need removal and business/private splits need judgement.
Use them to detect missing income, unusual costs and deteriorating margins rather than treating them as a pure filing exercise.
MTD does not remove the annual tax return
For tax years after an individual starts MTD for Income Tax, compatible software is used to complete and submit the tax return after the year-end adjustments have been made. The 31 January filing deadline remains central. MTD changes the route to that return; it does not remove the need to finalise the tax position.
That is why the correct architecture is digital records → quarterly summaries → year-end adjustments → final tax return → payment. Britvex sets out this wider system on its Making Tax Digital page and connects it with bookkeeping and Self Assessment rather than treating MTD as a standalone software purchase.
The next risk is 2027, not just 2026
Businesses below the £50,000 threshold can easily assume MTD is irrelevant. That can be a mistake. The £30,000 cohort starts in April 2027, so the 2025/26 return is already the measurement point for the next wave. A freelancer or landlord whose gross qualifying income has moved above £30,000 should be preparing the record-keeping system now, not in the final week before the mandate begins.
For growing businesses, this is also an opportunity. The same records needed for MTD can support cash-flow forecasting, management reporting and tax planning. Compliance data becomes commercially useful when it is kept current enough to answer questions during the year.
