Does using the HMRC app mean I'm signed up for Making Tax Digital?

No. They are separate things. The HMRC app is a personal service for checking your tax code, your pay, your National Insurance record and your Self Assessment position — useful, but it is a window, not a filing system. Making Tax Digital for Income Tax requires you to keep digital records and send quarterly updates through software that HMRC recognises, which the app does not do. You can be a daily app user and still be nowhere near compliant. If your qualifying income puts you inside the regime, you need compatible record-keeping software as well.

How do I know if I'm in Making Tax Digital for Income Tax?

It comes down to qualifying income: your gross income from self-employment and property, added together, before any expenses are deducted. Over £50,000 in 2024-25 and you were in from 6 April 2026. Over £30,000 in 2025-26 and you join from 6 April 2027. Over £20,000 in 2026-27 and you join from 6 April 2028. Because the test is gross rather than profit, plenty of businesses with modest profits are inside it. Our Making Tax Digital checker works out your start date and your deadlines in four questions.

Do I pay tax every quarter now?

No, and this is the most common misunderstanding about the whole regime. A quarterly update is a cumulative summary of income and expenses by category, sent through your software. No tax is calculated on it and nothing falls due when you send it. Your tax is still worked out once a year on the final declaration, which is due by 31 January, and payment dates are unchanged: the balancing payment on 31 January, with payments on account on 31 January and 31 July. What has changed is the frequency of reporting, not the frequency of paying.

What happens if I miss a quarterly update?

Late submissions run on a points system rather than an immediate fine. You collect one penalty point for each quarterly update or tax return deadline you miss, for tax years after 2026-27, and a £200 penalty is charged once you reach four points. Late payment is treated separately and more expensively: 3% of the outstanding tax at day 15, another 3% at day 30, then an annual rate of 10% charged daily from day 31, plus interest at 7.75%. In your first year inside the regime the day-15 charge is waived if you pay within 30 days.

If HMRC's app does so much, do I still need an accountant?

The app tells you what HMRC already knows about you. It does not tell you whether you are paying more than you need to, whether your salary and dividend split is sensible, whether a purchase is better made before or after your year end, or whether your records will stand up to a question. Those are decisions, not lookups, and the digital shift arguably makes them matter more, because the compliance side gets faster while the judgement calls stay exactly as hard. If anything, the useful accountant is the one who spends less time on data entry.

HMRC's app and what it means for your bookkeeping

Reacting to: 5.6 million taxpayers check their pay in the HMRC app an average of 18 times a year (gov.uk / HMRC) →

HMRC's latest Transformation Roadmap update carries some genuinely striking numbers. The HMRC app had 7.6 million unique users in 2025-26 — 2.8 million of them new, a 28% rise on the year before. Of those, 5.6 million used it specifically to check their pay, opening it 100 million times between them: an average of 18 times each over the year. HMRC is targeting 10 million app users by April 2027.

The rest of the release fills in the picture. HMRC says 20 million people used their Personal Tax Account in 2025-26, that 80% of customer interactions now happen through automated or digital self-serve channels, and that average call waiting times have roughly halved over two years, to 12.5 minutes.

The direction of travel isn't subtle

Whatever you make of Making Tax Digital as a policy, the pattern underneath it is now unmistakable. Tax administration in the UK is going digital-by-default, and it is going there partly because people are choosing it, not only because it is being mandated. One in seven PAYE taxpayers has already used the app. HMRC's letter volumes and its call waiting times are both falling as more moves online.

For a business owner the read-across is blunt. If HMRC's systems are built around real-time, always-current data, then running your books from a carrier bag of receipts and a spreadsheet updated once a quarter is going to get progressively more uncomfortable — and, more practically, it makes each deadline harder than it needs to be. The businesses that find this easy are the ones already working digitally out of habit, not the ones retrofitting it in the final fortnight.

The bit that actually lands on your desk: the timetable

Making Tax Digital for Income Tax started on 6 April 2026. Whether you are in it, and when, is decided by your qualifying income — your gross income from self-employment and property, before you deduct a single expense. It is not your profit, and that catches people out.

Over £50,000 of qualifying income in 2024-25 — you are in from 6 April 2026.
Over £30,000 in 2025-26 — you are in from 6 April 2027.
Over £20,000 in 2026-27 — you are in from 6 April 2028.

Two things about that test. First, it is gross. A sole trader turning over £55,000 with £20,000 of costs has a £35,000 profit and is still in from April 2026, because the number that counts is the £55,000. Second, it adds up. If you have a trade and a rental property, the two are combined for the threshold, even though they are reported separately. HMRC says more than 350,000 sole traders and landlords had enrolled by the time of this update. Our Making Tax Digital checker settles your own position in four questions.

The four dates that are now in your year

Once you are in, you send a quarterly update through recognised software. The standard update periods run 6 April to 5 July, 6 July to 5 October, 6 October to 5 January and 6 January to 5 April. The deadline is one month and two days after each period ends, which gives you four fixed dates:

7 August, 7 November, 7 February and 7 May.

You can elect to use calendar quarters instead — 1 April to 30 June and so on — and the four deadlines stay exactly the same. A quarterly update is a cumulative summary of income and expenses by category. It is not a tax return, nothing is calculated on it and no tax falls due with it. The tax return itself, now called the final declaration, is still due by 31 January, tax is still payable on 31 January, and payments on account still land on 31 January and 31 July.

Worked example: what leaving it to the last fortnight costs

Illustrative figures, and deliberately unremarkable ones. A sole trader turned over £68,000 in 2024-25, so is inside Making Tax Digital from 6 April 2026. The bookkeeping drifts, the final declaration goes in late, and a balancing payment of £9,400 for 2026-27 is settled 40 days after the 31 January 2028 deadline.

Days 1 to 15 late: nothing.
Day 15: 3% of the tax outstanding — £282.
Day 30: a further 3% — £282.
From day 31: an annual rate of 10%, charged daily. Ten days on £9,400 is £25.75.
Late payment interest at 7.75% — the Bank of England base rate of 3.75% plus four percentage points, the rate in force since 9 January 2026. Forty days on £9,400 is £79.84.

That is £669.59 on top of the tax, for forty days of drift. In your first year inside the regime HMRC waives the day-15 charge if you clear the balance within 30 days — but once you are past day 30, both 3% charges apply regardless. Late quarterly updates are handled separately, through penalty points: one point for each update missed, for tax years after 2026-27, and a £200 penalty once you reach four points.

None of that is a penalty for being bad at tax. It is a penalty for being late, which is a diary problem, and diary problems are the cheapest kind to fix.

The letters change is the one most people will miss

From summer 2027, HMRC will move over 100 types of personal tax letter online for the first time. Those letters account for more than half of the roughly 120 million it posts each year, and HMRC is targeting up to 75% fewer letters by 2028-29, saving around £50 million a year. It has already cut 15 million letters over the last three years.

The practical consequence is easy to overlook: the post stops being how you find out. If nobody logs in, notices are missed — and a missed notice is still a missed deadline. Two housekeeping jobs follow from that. Make sure the log-in details for your tax account exist somewhere other than one person's memory, and make sure the email address HMRC holds for you is one that a human actually reads.

What to do this week

Add up your gross self-employment and rental income for 2024-25 and for 2025-26, before expenses. That figure, not your profit, decides when you are in.
Put 7 August, 7 November, 7 February and 7 May in the calendar as recurring entries, with a reminder a fortnight before each.
Confirm the software you keep your records in is on HMRC's recognised list for Making Tax Digital for Income Tax. A spreadsheet on its own is not enough unless it is linked to compatible software.
Log in to the HMRC app or your Personal Tax Account and check the email address on file.
Pick the day of the month you do your bookkeeping, and treat it as an appointment. HMRC reports that the two million businesses already inside Making Tax Digital for VAT save between 26 and 40 hours a year on administration.

The honest summary

The app numbers are a symptom, not the story. The story is that HMRC is rebuilding around current data, and businesses whose numbers are only current once a year will feel every deadline as an event. That is the whole case for digital accounting run through a platform like FreeAgent or Xero rather than bolted on at year end: your figures exist in one place, continuously, in a format that feeds HMRC's requirements instead of needing translating first. If you have not moved yet, our explainer on Making Tax Digital covers what changes and when, and cloud bookkeeping covers what handing the record-keeping over actually involves. The deadlines are not moving to meet you.

5.6 million people now check their tax on an app. Why is your bookkeeping still on paper?
