A major change to how the UK’s smallest businesses report their income has arrived, and many of those affected still don’t know it is here. From April 2026, sole traders and landlords with income above £50,000 must keep digital records and send HMRC an update every three months, instead of filing one tax return a year. HMRC estimates that around 864,000 people fall into this first wave.
For anyone used to a single January deadline, this is the biggest shift in how personal tax is reported in a generation.
What is actually changing
The scheme is called Making Tax Digital for Income Tax. In plain terms, it swaps one annual Self Assessment return for four quarterly updates through the year, followed by a final declaration after the tax year ends. Each quarterly update is a running total of your income and expenses rather than a full tax bill, so it is lighter than a return, but it happens four times as often. HMRC is keen to stress that these updates are light-touch summaries, not four extra tax returns, and that the totals come straight from your software rather than being worked out by hand.
You also have to keep your records in software that connects to HMRC, rather than on paper or in a notebook. For many small operators who have always kept a shoebox of receipts and tidied it up once a year, that is the real change. The stated aim is to cut errors and give people a clearer view of what they owe as they go. The trade-off is more frequent admin and, for many, the cost of proper software for the first time.
Who has to use Making Tax Digital, and when?
The £50,000 line is only the starting point. The threshold is set to fall in stages, which is why this story matters to far more people than the first wave.
● From April 2026: income above £50,000.
● From April 2027: income above £30,000.
● From April 2028: the government plans to bring in those above £20,000.
The word that trips people up is income. It means your gross income from self-employment and property before you take off any expenses, not your profit. Someone with a modest rental flat and a small trade on the side can reach these figures more easily than they expect, and a landlord with two properties can be well past £50,000 while making very little once the mortgage is paid. If you judge yourself only on what you actually keep, you may assume you are safe when you are not. HMRC works this out from the figures on your most recent tax return, so the start date in April 2026 is based on what you earned in the 2024 to 2025 tax year.
The one piece of good news
HMRC has softened the start. Anyone joining in April 2026 will not pick up penalty points for late quarterly updates during the first 12 months, which gives people a year to find their feet. After that, late updates can trigger points, and a £200 penalty applies once four points build up. It is a sensible grace period, but it is easy to read it as permission to ignore the whole thing for a year, which would be a mistake.
How it works in practice
The rhythm is set by four update dates that fall on the same days each year: 7 August, 7 November, 7 February and 7 May. For the first wave, these cover the 2026 to 2027 tax year. You send a short summary by each date, then finish with a return that pulls the whole year together.
One point reassures people once they hear it. The year-end tax return does not vanish. If you join in April 2026, you still file your 2025 to 2026 return in the usual way by 31 January 2027, because that year sits before the new rules begin. Your first return under the new system covers 2026 to 2027 and is due by 31 January 2028. By then your software already holds the quarterly figures, so there is no last-minute hunt for receipts in January.
You will need software that HMRC recognizes. There are paid packages, but there are also free options for people with simple affairs, so going digital does not have to add a big cost. Anyone who truly cannot work online, for reasons such as age, disability or where they live, can apply to be exempt rather than being pushed onto a computer.
The penalty system is built to forgive the odd slip. If you stay below the four-point threshold, each point drops off on its own 24 months after the deadline you missed. It targets people who ignore the rules again and again, not someone who files late once.
Other 2026 tax changes for small businesses
This new rule arrives on top of several other changes that make 2026 an expensive year for small businesses.
The income tax thresholds are now frozen until April 2031, three years longer than previously planned. Because the personal allowance and the higher rate band do not rise with wages, more of your income slips into tax each year, and more people are pulled into the higher rate without any headline rate going up. This quiet effect, often called fiscal drag, is forecast to raise several billion pounds a year and to pull hundreds of thousands more people into income tax by the end of the decade.
Company directors who pay themselves in dividends also saw the tax on that income rise from April 2026, with the basic rate now 10.75% and the higher rate 35.75%, while the additional rate remains unchanged. Employers are carrying a heavier National Insurance bill at 15%, and the National Living Wage has risen to £12.71 an hour for staff aged 21 and over. None of these is dramatic on its own. Together they leave less room for error.
What to do now
If you think you are in the first wave, the useful steps are simple.
Start by working out your gross income from trade and property for the last full year and comparing it to the £50,000 line. If you are over it, or close, look at software now rather than in March. Getting your records into a digital system early turns the quarterly updates into a quick routine instead of a scramble every three months.
It also pays to get comfortable with the everyday numbers. Many sole traders moving into this system are growing, and growth can push them towards the £90,000 point where registering for VAT becomes compulsory. Keeping a close eye on your turnover, and using a quick VAT Calculator to check the tax on a price before it lands on an invoice, helps you avoid the small mistakes that can cost money at the worst possible time.
Finally, set calendar reminders for the quarterly dates and set aside a little money for tax as it comes in. If your affairs are more involved, an accountant is worth the fee this year in particular, both to pick the right software and to make sure the definition of income does not catch you out.
The bigger picture
Making Tax Digital has been delayed more than once, so some people assumed it would slip again. This time the dates are holding, and the direction is clear. The government wants tax reported closer to real time, and the threshold is only going to fall. Sole traders and landlords who treat 2026 as the year to get organized will find the later stages far easier than those who wait until they are forced.
For Britain’s huge number of small operators, the takeaway is simple. The once-a-year tax return is on its way out, and the sooner you build the habit of keeping digital records, the less painful the change will be.
