Making Tax Digital for Income Tax: What Launches in April 2026
By calculatemysalary.co.uk Editorial Team
Making Tax Digital for Income Tax becomes mandatory from April 2026 for self-employed individuals and landlords earning over £50,000. Here is what changes, who is affected, and how to get ready.
Making Tax Digital is finally coming. April 6, 2026. Years of delays, but it's happening. If you're self-employed or a landlord earning over £50k, this changes everything about how you file taxes. No more annual returns. Four quarterly updates instead. Different workflow, different software, different rhythm. This isn't a small change. If this applies to you, you need to start thinking about it now.
What Actually Changes
Out goes the annual Self Assessment return. In comes four quarterly updates a year through special software. You send HMRC income and expenses updates on a rolling basis instead of panicking in January with 12 months of receipts. It sounds more burdensome upfront, but it forces better record-keeping throughout the year — which actually might help you spot things you're missing on deductions.
Who Must Comply from April 2026?
From 6 April 2026, MTD for Income Tax is mandatory for individuals with qualifying income above £50,000 from self-employment or property. This affects approximately 780,000 self-employed individuals and landlords.
Phased rollout
| Date | Income Threshold | Estimated Number Affected |
|---|---|---|
| April 2026 | Over £50,000 | ~780,000 |
| April 2027 | Over £30,000 | ~970,000 additional |
| April 2028 | Over £20,000 | Further expansion |
Partnerships and incorporated companies are not currently affected by these changes.
How Quarterly Reporting Works
You need to keep digital records now. That means MTD-compatible software — paper and spreadsheets don't count (unless you use bridging software to convert them). Four times a year you submit updates: income and expenses for each quarter by set deadlines (7 August, 7 November, 7 February, 7 May). These aren't tax calculations — just data. Your actual tax bill gets calculated in a final declaration at year-end, which replaces your old Self Assessment return.
Your payment schedule stays the same. Still pay once or twice a year on the usual timeline. Quarterly updates don't change when you pay tax — they just change when you report it.
What Software Do You Need?
HMRC maintains a list of MTD-compatible software. Popular options include Xero, FreeAgent, QuickBooks, and Sage. Many already support MTD for VAT and are adding Income Tax functionality.
If you use a spreadsheet today, you will need either to switch to compatible software or use bridging software that converts your spreadsheet data into the required digital format.
What Happens If You Make a Mistake?
If you make an error in a quarterly update — such as omitting an expense — you can correct it in the next quarterly submission rather than amending the earlier one. There is no need to resubmit previous quarters.
Penalties
HMRC has indicated that penalties for late quarterly updates will not apply during the initial testing phase, giving users time to adjust to the new system. However, MTD for Income Tax is a statutory requirement from April 2026, and penalties for non-compliance will apply once the grace period ends.
Exemptions
You may be exempt if digital compliance is not reasonably practicable due to age, disability, or remote location. You need to apply for an exemption and provide supporting evidence.
What You Need to Do Before April
Check your 2024/25 Self Assessment to see if you're over £50,000. If you are, pick your software now. Get comfortable with it. Start keeping records digitally even before April so it's not a shock in June. If you use an accountant, talk to them about how they support MTD and which software they prefer. HMRC has a testing programme if you want to try it early.
How This Relates to Your Take-Home Pay
If you are self-employed, your take-home pay after tax is directly affected by how efficiently you track expenses. Quarterly reporting encourages better record-keeping, which may help you claim legitimate deductions you might have otherwise missed at year-end.

The Real Implication
This is a shift in how HMRC monitors self-employment and rental income. More frequent reporting means more chances to catch issues, more data flowing to the tax authority. But it also means less of a mad scramble in January. Honestly? For some people, the discipline of quarterly updates forces better financial management, which isn't a bad thing. The key is picking software now and getting comfortable with it — don't wait until March.
