Making Tax Digital: HMRC automatic sign-up, falling thresholds and the cashflow wake-up call

This article was originally published in July 2026, shortly after Making Tax Digital for Income Tax became mandatory for the first group of sole traders and landlords.

Since then, an important implementation change has taken place. HMRC has begun automatically signing up some people who should already be using Making Tax Digital for the 2026/27 tax year but have not signed themselves up.

The original article below remains relevant, particularly its explanation of qualifying income, falling thresholds and the distinction between tax reporting and tax planning. We have updated sections where events have moved on and added a new section explaining HMRC's automatic sign-up programme and what people affected may need to do next.

Every January, the same scramble happens. Receipts are found, bank statements are downloaded, spreadsheets are patched together and the Self Assessment deadline suddenly becomes very real.

For some people, that annual scramble is irritating but manageable. For others, particularly people with irregular income or limited cash reserves, it can expose a much bigger problem.

Making Tax Digital for Income Tax changes the reporting rhythm. People within the regime must keep appropriate digital records and send quarterly updates to HMRC using compatible software.

But quarterly reporting does not mean quarterly tax payment.

Quarterly reporting tells HMRC what has happened. It does not make sure you have the cash available when the tax becomes payable.

That distinction matters increasingly as MTD moves towards people with smaller self-employed, freelance and property income streams.

For the 2026/27 tax year, Making Tax Digital for Income Tax generally applies to an individual who is registered for Self Assessment, receives income from self-employment as a sole trader, property, or both, had qualifying income of more than £50,000 in 2024/25, and is not exempt.

Those people were required to start using MTD for Income Tax from 6 April 2026.

The word more matters. Someone with qualifying income of exactly £50,000 does not cross the 2026 threshold. The same principle applies to the future £30,000 and £20,000 thresholds.

The rollout is based on qualifying income from an earlier tax year.

More than £50,000 of qualifying income in 2024/25 brings MTD in from 6 April 2026.

More than £30,000 of qualifying income in 2025/26 brings MTD in from 6 April 2027.

More than £20,000 of qualifying income in 2026/27 brings MTD in from 6 April 2028.

These are confirmed stages of the MTD rollout, not speculative future proposals.

Your 2025/26 income can determine whether you enter MTD in April 2027, while income you are earning during 2026/27 can determine whether you enter in April 2028.

So April 2028 may sound distant, but the income HMRC will use to assess that £20,000 threshold is being earned now.

One of the easiest ways to misunderstand MTD is to think of the threshold as the size of a single business. It is not necessarily.

HMRC defines qualifying income broadly as your total gross income from self-employment and property before expenses. That total can include more than one source of self-employment or property income.

For example, HMRC gives the example of someone with £25,000 of rental income and £27,000 of self-employment income. Their qualifying income is £52,000.

Neither income source reaches £50,000 by itself. Together, they do.

That becomes even more significant as the threshold drops.

The threshold is also based on relevant gross income before expenses, not the profit you eventually make.

Imagine a sole trader with £35,000 turnover, £17,000 of allowable business expenses and £18,000 left before personal tax.

For the £30,000 MTD threshold, it is the relevant gross income that matters, not simply the £18,000 left after those expenses.

Likewise, a landlord could receive substantial gross rent but have considerably less cash left after mortgage costs, repairs, insurance, agent fees and periods without a tenant.

That is one reason MTD can reach activities that do not necessarily feel like large or particularly profitable businesses.

Qualifying income is calculated for the individual.

Relevant self-employment and property income can combine, but that does not mean all household or personal income is added together.

Someone earning £55,000 from employment plus £22,000 of qualifying property income would not have £77,000 of qualifying income. For MTD purposes, the relevant figure in that example would broadly be the £22,000 property income.

By contrast, someone receiving £18,000 gross from freelance work and £14,000 of qualifying property income could have £32,000 of qualifying income because both sources count.

Joint property ownership also needs care. HMRC says it is normally the individual's share of the relevant property income that counts towards their qualifying income.

People inside MTD need compatible software to create and maintain digital records and send quarterly updates.

The standard update deadlines are 7 August, 7 November, 7 February and 7 May.

The quarterly updates are cumulative. For example, the second standard update covers the period from 6 April to 5 October, rather than reporting only the second three months in isolation.

They are summaries of relevant records, not four separate annual tax returns.

MTD has not moved the full Income Tax bill onto a quarterly payment timetable.

HMRC says the tax return and tax due remain payable under the relevant Self Assessment timetable, with the full tax bill normally due by 31 January following the end of the tax year.

Payments on Account also remain important. Where they apply, they are normally paid on 31 January and 31 July and are usually based on the previous year's relevant tax bill.

That is why reporting frequency and financial readiness are two different things.

This is the most important development since this article was first published.

From September 2026, HMRC says it will begin signing up, in stages, people who should already be using MTD for the 2026/27 tax year, had qualifying income above £50,000 in 2024/25, and have not already signed themselves up.

HMRC will contact people after it has signed them up. The process will take place over the coming months.

HMRC signing someone up does not create their MTD obligation.

If they met the criteria, the obligation already existed from 6 April 2026. HMRC's automatic sign-up programme is dealing with people its records indicate should already have joined the regime.

Automatic sign-up does not mean HMRC has done everything necessary on your behalf.

HMRC says people it signs up need to take further steps. These include accessing the MTD service through HMRC online services, checking that HMRC's record of their self-employment and property income sources is correct, obtaining compatible MTD software, and catching up on digital record keeping and any overdue quarterly updates.

Being signed up is not the same thing as being compliant.

HMRC may have enrolled you into the service, but it does not maintain your business records or submit the information from your compatible software for you.

Source: https://www.gov.uk/guidance/check-what-to-do-if-hmrc-has-signed-you-up-for-making-tax-digital-for-income-tax

HMRC says its automatic sign-up uses information it already holds, including information from the 2024/25 Self Assessment tax return.

Circumstances may have changed since that return was submitted. A self-employment may have stopped, a property may no longer be rented, a new income source may have started, the way income is structured may have changed, or the person may believe an exemption applies.

HMRC therefore asks people it signs up to check and confirm the income sources it holds for them.

If all relevant self-employment and property income sources stopped by 5 April 2026, HMRC says MTD may not be required for 2026/27 once the records are corrected. Different rules can apply where an income source ceased after the tax year started.

If you believe HMRC has signed you up incorrectly, or think an exemption may apply, check the position with HMRC and, where appropriate, a tax professional rather than simply ignoring the notification.

There is another practical consequence of HMRC beginning automatic sign-up in September.

The first standard quarterly-update deadline for 2026/27 was 7 August 2026.

Someone being automatically enrolled now may therefore already have an overdue quarterly update.

HMRC says those people need to create the necessary digital records from the start of the tax year and send overdue quarterly updates as soon as possible.

There is an important first-year transition. HMRC will not issue penalty points for missing quarterly-update deadlines during 2026/27.

But this does not mean MTD deadlines can simply be ignored. The digital records and quarterly updates still need to be completed, and HMRC says the quarterly updates must be sent before the MTD tax return can be submitted. Penalty rules still apply to late tax returns and tax payments.

The September 2026 automatic sign-up programme is aimed at people HMRC believes should already be inside MTD because their 2024/25 qualifying income was above £50,000.

It should not be confused with the later rollout.

The next thresholds remain more than £30,000 of qualifying income in 2025/26, bringing MTD in from April 2027, and more than £20,000 of qualifying income in 2026/27, bringing MTD in from April 2028.

So HMRC automatic sign-up is the immediate story. The falling threshold is the much bigger long-term story.

The staged thresholds make this increasingly relevant to people who may not think of themselves as running a substantial business.

Employment plus freelance work: someone earns £45,000 through PAYE employment and £32,000 gross from freelance work during 2025/26. Their salary does not count towards the MTD qualifying-income test, but the £32,000 freelance income does. Because it is more than the £30,000 threshold, they could need to use MTD from April 2027, subject to the detailed rules and any exemption.

Employment plus a rental property: someone earns £55,000 from employment and receives £22,000 of qualifying gross property income during 2026/27. Again, the salary does not count, but the £22,000 property income is more than the £20,000 threshold for the April 2028 phase.

Freelance work plus property income: someone earns £18,000 gross from freelance work and £14,000 of qualifying property income. Their combined qualifying income is £32,000. Neither activity crosses £30,000 on its own. Together, they do.

Several smaller self-employed income streams: someone earns £12,000 from tutoring, £11,000 from consultancy and £9,000 from another sole-trade activity. The total is £32,000. Again, no individual activity looks particularly large, but the combined qualifying income is what matters.

These examples are simplified. Individual circumstances, exemptions and exactly how income must be reported can change the result, so HMRC guidance or professional tax advice should be used where the position is uncertain.

A well-established consultant with clean records, a dedicated business account, substantial reserves and an accountant may find MTD inconvenient but manageable.

Someone with irregular work, seasonal income, mixed household commitments and limited savings may experience it very differently.

The problem is not only tax. It is timing.

A strong month can make the bank balance look healthy. But some of that money may already be needed for tax, business expenses, VAT where relevant, a quieter trading period, repairs or maintenance, insurance, software or accounting costs, or ordinary household spending.

The balance in the bank is not necessarily the amount available to spend.

That is particularly important for people whose business and household finances interact closely.

This is the central financial-planning distinction.

MTD can make people report business activity more regularly.

It does not automatically reserve money for tax, predict a weak trading period, fund a January balancing payment, fund a July Payment on Account, deal with a major household expense arriving in the same month, make seasonal income predictable, or tell you whether the income stream is worthwhile after tax, expenses, time and administration.

A person can therefore be completely up to date with their MTD reporting and still face a serious tax cashflow problem.

For someone with variable income, the useful question is not simply: Have I reported this quarter?

It is: If income weakens, expenditure rises or the eventual tax bill is higher than expected, what happens to my household cash position?

The annual January rush has always hidden a larger problem.

If you only really understand your freelance, rental or side-business income when you prepare a tax return, you are discovering its financial effect after most of the decisions have already been made.

MTD may encourage more regular record keeping. That can be useful.

You may spot unpaid invoices sooner, understand expenses more clearly, build a more deliberate tax reserve and see earlier whether an income stream is actually improving your finances.

But bookkeeping and financial planning are still different activities.

Compatible MTD software can help you meet reporting obligations. It does not necessarily answer whether the household can afford a three-month income dip, whether enough money is being reserved for tax, what happens if a Payment on Account coincides with a large annual expense, whether a rental property is improving household cashflow, whether occasional consultancy still makes sense after expenses and tax, or whether earning more this year creates a different tax or MTD position next year.

Those are planning questions.

Freelancers and consultants often have uneven income and delayed payments. A few strong months can create a sense of financial security that disappears quickly when work slows. Track not only income already received, but expected invoices, tax reserves, business costs and weaker future months.

Sole traders and people with several side businesses can see gross income climb faster than profit. A collection of relatively modest activities can also combine to push qualifying income above an MTD threshold.

People who are mainly employees may be particularly likely to overlook the change. PAYE salary itself does not count towards the MTD qualifying-income threshold, but relevant consultancy, tutoring, creative, trading or other self-employed side income can.

For people with property income, rental cash left after repairs, void periods, insurance, finance costs and tax may be much less stable than the gross rent suggests.

For MTD, UK properties are generally treated as one UK property business rather than requiring separate MTD businesses for each property. For financial planning, however, understanding the performance and cash demands of individual properties can still be useful.

People approaching retirement may use consulting, freelance work, part-time self-employment and rental income to bridge the period between full-time work and retirement. A £20,000 or £30,000 gross income stream can look attractive without necessarily producing the same amount of usable household cash.

September 2026 update: When this article was first published, we advised readers not to wait for HMRC to contact them. HMRC is now actively signing up some people who should already be using MTD. The underlying advice remains the same: do not assume that lack of correspondence means you are outside the regime. HMRC says individuals remain responsible for checking whether and when they need to use MTD.

For compliance, you need to understand HMRC's record-keeping and reporting requirements and use compatible MTD software where required.

For financial planning, the useful shift is from annual tax-return thinking to understanding the household cash position through time.

Planiva is not MTD accounting or filing software. It does not keep the digital business records required by Making Tax Digital or submit quarterly updates to HMRC.

Planiva's role is different.

Its Cash Flow Planner can help you place income, household spending, known future costs and tax payments onto a timeline and see how your cash position could develop over the next one to five years.

That can be useful where income is irregular or where tax obligations collide with other household commitments.

You could model a weaker three-month trading period, a large January tax payment, a July Payment on Account, an unexpected property repair, a reduction in freelance work, a higher or lower tax assumption, or whether a side income remains worthwhile once its wider cashflow effect is considered.

Planiva's Tax Planner can also help explore tax scenarios as part of the wider household plan.

The aim is not to replace your accountant, tax software or HMRC guidance. It is to answer a different question: What could all of this mean for the money available to your household?

Making Tax Digital for Income Tax has moved into a different phase.

For the first cohort, it is no longer something coming in the future. It has been mandatory since April 2026, the first quarterly deadline has passed, and HMRC is now beginning to sign up people who should already be using it.

At the same time, the threshold falls from more than £50,000 to more than £30,000 in April 2027 and then more than £20,000 in April 2028.

That means MTD is moving steadily towards people with increasingly ordinary levels of freelance, sole-trade and property income.

But the underlying financial issue has not changed.

Reporting income more frequently does not make that income more predictable. And telling HMRC what has happened does not reserve the cash needed for the eventual tax bill.

MTD may force better record keeping. Use that as a prompt to improve the financial planning around it as well.
