HMRC's biggest shake-up of tax administration in a generation — moving from annual paper returns to digital records and regular online updates.
Making Tax Digital is the largest change to how UK tax is administered in decades. It does not change how much tax you pay — the rates and allowances stay the same — but it fundamentally changes the how: digital records instead of shoeboxes of receipts, and regular online updates instead of one annual return. For sole traders, the countdown to April 2026 is now real.
At its core, MTD is built on two requirements. First, you must keep your records digitally — income and expenses recorded in software or a spreadsheet linked to HMRC, not on paper. Second, you must submit information to HMRC through that software at set points in the year, rather than typing figures into a return once annually.
The programme is rolling out in stages by tax type:
MTD for Income Tax phases in by income level, measured by your qualifying income (gross self-employment plus gross property income, before expenses):
| From | Applies to qualifying income over |
|---|---|
| 6 April 2026 | £50,000 |
| 6 April 2027 | £30,000 |
| 6 April 2028 | £20,000 |
So a sole trader with £60,000 of turnover joins in April 2026; someone with £35,000 joins in April 2027. The threshold is based on gross income, not profit — a crucial point for businesses with high turnover but thin margins. Check where you stand with the MTD eligibility checker.
Consider Rachel, a self-employed graphic designer. In the 2024/25 tax year (the year HMRC looks back to) she had £58,000 of gross trading income and £14,000 of expenses, leaving a profit of £44,000.
Although her profit is below £50,000, MTD uses gross qualifying income, which is £58,000. Because that exceeds £50,000, Rachel must comply with MTD for Income Tax from 6 April 2026. From that date she keeps digital records, sends four quarterly updates a year, and files a final declaration after year-end. Plan the cash and the rhythm with the quarterly planner.
HMRC's stated aim is to reduce the "tax gap" — the difference between tax owed and tax collected — much of which it attributes to avoidable errors in manual record-keeping. Digital records and more frequent updates are intended to make mistakes less likely and tax affairs more current. For businesses, the upside is meant to be better visibility of what they owe throughout the year, rather than a once-a-year reckoning. The transition cost — new software, new habits — is the trade-off, which is why preparing early matters.
Making Tax Digital does not raise your tax bill; it changes the way you keep records and talk to HMRC. The businesses that prepare early will barely notice the switch.
MTD introduces a points-based penalty system for late submissions. Each missed quarterly update or declaration earns a penalty point; reach the threshold (four points for quarterly filers) and a £200 penalty applies, with further £200 charges for each subsequent default. Late payment is handled separately, with interest plus escalating percentage penalties. The system is designed to be more proportionate than the old flat penalties, forgiving the occasional slip while penalising persistent lateness.
