On 6 April 2026, MTD for Income Tax went live for sole traders and landlords earning more than £50,000. HMRC's own press release put the number at 864,000 people who are now in scope from this tax year onwards. The reaction in most affected businesses has been a mix of "do I need to do anything different next week?" and "is this a tax thing or a software thing?".
It is both, but mostly the second one. The rule is a rule about how you keep your records and how often you send them to HMRC. It is not a change to what you owe. This post explains what changed, what it means for your daily operations, what the 12-month penalty grace period actually gets you, and what is worth doing about it this week if anything.
What MTD for Income Tax actually is
MTD for Income Tax is the second phase of HMRC's longer-running Making Tax Digital programme, which started with VAT in 2019. The headline change is that sole traders and landlords above the income threshold now have to:
- Keep their business records in digital form. Not on paper, not in a spreadsheet you never share.
- Use HMRC-recognised software to file four quarterly updates per tax year, plus a Final Declaration at the end.
- Replace the annual Self Assessment return with the Final Declaration. Self Assessment for the 2025 to 2026 tax year is the last one. From 2026 to 2027 onwards, the Final Declaration takes its place.
A "quarterly update" is not a tax return. It is a summary of income and expenses for the quarter, submitted to HMRC through the software. The final reconciliation, where you actually settle the bill, still happens once a year.
Who has to comply, and when
The rollout is in three phases by income threshold. The dates are the start of the tax year you have to be using MTD for Income Tax from.
- 6 April 2026, for sole traders and landlords with qualifying income over £50,000 in the 2024 to 2025 tax year.
- 6 April 2027, for those over £30,000 in the 2025 to 2026 tax year.
- 6 April 2028, for those over £20,000 in the 2026 to 2027 tax year.
The income threshold is calculated on the tax year that ended two years earlier. So if your 2024 to 2025 turnover was under £50,000, you do not have to do anything yet. The £30,000 threshold catches you next year, the £20,000 one the year after that. By 2028, MTD for Income Tax covers most self-employed people in the UK.
What changes in your daily operations
This is the part where the boring practical question lives. The honest version: nothing has to change in the work itself. What changes is the plumbing under the work.
Before April 2026, a sole trader could keep a shoebox of receipts, hand it to an accountant in December, and stay compliant. After April 2026, that workflow does not work for the income groups in scope. The records have to be digital from the moment they are created, or shortly after.
In practice that means one of:
- You move to bookkeeping software that has HMRC-recognised MTD support. Xero, QuickBooks, FreeAgent, Sage all do this. You enter income and expenses there throughout the quarter, and the quarterly update is generated and submitted from inside the software.
- You keep using spreadsheets but bridge them to HMRC with bridging software that pulls the data into the required format. HMRC has a list of recognised software for both routes.
- You hand the whole thing to your accountant, who runs the software on your behalf and files for you. Most accountants who used to file your Self Assessment will offer this as a service. The fee usually increases.
The least disruptive route depends on what you already do. If you already use bookkeeping software, you may need to do nothing more than enable the MTD setting and pick a quarterly cadence. If you still send receipts in plastic wallets to your accountant once a year, the workflow change is real.
The 12-month penalty grace period
There is a 12-month window where HMRC will not issue penalty points for late quarterly updates if you join MTD for Income Tax in April 2026. This was legislated in the Autumn Budget 2025 to 2026 and is documented in HMRC's penalty guidance for MTD. It is more generous than it looks, but read it carefully. It does not mean you can skip the quarterly updates. It means that if you are late, the first year of mistakes will not count toward the points-based penalty system. You still owe the data. You just have a runway for getting the workflow right.
The grace period only applies to the four quarterly updates in the 2026 to 2027 tax year. It does not apply to the end-of-year Final Declaration, which is still due by 31 January 2028 with full penalties for lateness. And it only applies to the April 2026 cohort. If you are in the £30,000 bracket landing in 2027, your runway is shorter.
What to actually do this week
If your 2024 to 2025 income was above £50,000 and you have not yet picked a software path, this is overdue. The first quarterly update covers 6 April to 5 July 2026 and is due by 5 August 2026. That is about three months away.
Three questions in the order they matter:
- Are your records already digital and current? If yes, the change is mostly a software setting and a cadence. Talk to your accountant about whether to file yourself or have them do it.
- Are your records partly digital, partly in a notebook or in receipts? Plan the next 60 days as a one-time tidy. Pick one tool, get the historic stuff in, then run the new cadence from there.
- Are your records almost entirely paper, or scattered across email and bank statements? This is where it gets interesting. You probably do not need bookkeeping software with all the bells. You need a plain workflow that captures the four or five categories of income and expense you actually have, and a way to push that to HMRC-recognised bridging software quarterly. That is closer to a custom build than a SaaS subscription.
The bureau builds the third category fairly often. A small Python script that pulls bank transactions, asks you to categorise the new ones once a week, and produces the quarterly summary ready for bridging software is a one-time fix that replaces the annual scramble.
Where this is not advice
This post is not tax advice and it is not regulatory advice. The bureau builds the workflow tools that turn an HMRC rule into clean daily work. Whether the rule applies to you, whether your specific income counts as qualifying income, and whether your accountant should change anything about how they file for you, are all questions for your accountant or a registered tax adviser. The point of this post is to explain the operational shape of the change clearly enough that the conversation with your accountant is short and useful.
If your operations have outgrown the once-a-year accountant routine and you are now thinking about what your day-to-day records workflow should look like, the 15-minute triage is the right starting point. It is free, it is honest, and roughly half the time the answer is "this is a software-purchase decision, not a custom build".
