If you’re a sole trader or landlord in the UK, you’ve probably heard whispers about the upcoming shake-up in the tax system. From April 2026, HMRC will be rolling out its Making Tax Digital (MTD) rules for Income Tax, and while that might sound like just another bureaucratic change, it’s actually a fundamental shift in how you’ll manage your tax affairs.
Instead of submitting one big tax return once a year, you’ll be asked to keep digital records and report your income and expenses throughout the year. For some, that might sound daunting. For others, it may be a welcome step toward better organisation and fewer tax-time surprises. But either way, the changes are coming, and it's well worth taking some time to understand what is actually going on, how it will affect you, and what you need to do to prepare.
Understanding MTD for Income Tax
Making Tax Digital is HMRC's long-term ambition to bring the UK tax system into the digital world. It's a very straightforward idea: by moving away from paper or annual reporting, HMRC aims to make reporting more accurate, less wrong, and less hassle for taxpayers in the long run.
You may already be familiar with MTD if you’re VAT-registered, since digital VAT reporting has been in place for some years. The same concept is now being extended to Income Tax. Instead of recording your business or property income in whatever format you’ve been using, and then filling in a Self-Assessment once a year, you’ll need to keep digital records and send regular updates to HMRC using approved software.
Who Needs to Comply & When?
Not everyone will be caught by MTD right away. HMRC is phasing in the changes gradually, with income thresholds to determine when you’ll be brought into the system.
If your combined gross income from self-employment and property is more than £50,000 a year, you’ll need to comply from April 2026. A year later, in April 2027, the threshold drops to £30,000. And in April 2028, it lowers again to £20,000.
It's also important to note that HMRC looks at your most recent tax return to see if you fall within the regime. Let's say, for example, in 2024–25 you have £52,000 of overall rental and self-employment income. You'll need to put MTD in April 2026. If your income was £28,000, though, you won't be affected until at least April 2027.
And just to be completely sure, these limits are in respect of gross income, i.e. the whole before expenses or reliefs are deducted. So even if you are making a modest profit after expenses, it's your gross that matters.
Example 1:
Imagine you’re a landlord with three rental properties. Each property brings in £1,500 per month in rent, which adds up to £54,000 in gross rental income a year. Even if your repairs, property insurance and other expenses reduce your profit to £35,000, HMRC still sees your gross figure of £54,000. That means you’ll need to follow MTD rules from April 2026.
Example 2:
Now look at another landlord who owns just one property, rented for £1,200 a month, earning £14,400 a year. In addition to this, they also own a small internet business which does turnover of £12,000 a year. Between them, their gross is £26,400. This will mean that they will not have to report until at least April 2028, when the threshold drops to £20,000.
What Will Change in the Way You Report?
One of the biggest differences with MTD is that the reporting frequency is so much higher. At the moment, you might be used to spending January rushing through a year's worth of paperwork in an attempt to get your Self-Assessment in on time. With MTD, that part of the annual return will be replaced by a series of electronic updates scattered throughout the year. However, you must still submit the annual declaration by 31 January, which serves the same purpose as a Self-Assessment tax return.
You will need to use software that is MTD-compatible, like RentalBux, in order to record all your income and expenditure. Spreadsheets are still possible, but they need to be linked to HMRC digitally via so-called "bridging software". Paper records, however, are no longer acceptable.
Each quarter, you'll send a digital report to HMRC with a summary of the income and expenses for the quarter. These quarterly reports don't have to be absolutely spot on or cover all adjustments, but they provide HMRC with an ongoing snapshot of your finances. At the end of the tax year, you can make all the accounting and tax adjustments, claim allowances for reliefs, include all other incomes (e.g. interest income, dividend income etc.) and file a final declaration.
Example 3:
Let's say you're a freelance graphic designer. Between April and June, you earn £12,000 and have business expenses worth £3,000. You'll have a quarterly update of £12,000 earnings and £3,000 expenses. Between July and September, you earn £8,000 with £2,000 in expenses, and you'll have a further update with such figures. At the end of the tax year, you will have four quarterly updates on your files. Then, through your software, you’ll submit adjustments such as home office allowances or capital purchases. The final tax bill is still due the following January, but HMRC has seen your numbers build up throughout the year.
What Will Stay the Same?
There are a lot of misconceptions about MTD, so let's get rid of a big one straight away: you won't be paying tax four times a year. The reporting may be quarterly, but the deadlines for paying taxes remain the same as they are today. That is, most of your tax remains due to 31 January at the end of the tax year, with the July payments on account still applicable where relevant.
Personal allowances, tax bands, and National Insurance contributions remain unchanged. So while the process may look different, the end result in terms of how much you pay does not change.
What About Penalties?
HMRC is also introducing a new penalty system with MTD, and it is quite different from the old regime. Instead of automatically issuing a fine for late filing, the new regime will work on penalty points. Each missed filing adds an additional point. You receive a financial penalty when you reach a certain number of points.
Example 4:
Miss your April–June quarterly update, you get one penalty point. Miss the next update, you've got two points. Keep going and reach four points, HMRC writes to you with a £200 penalty. The points stay on your record until you file on time for a certain period, after which they fall off.
There's also late payment charges, which are now a proportionate rather than a fixed amount. Instead of a one-off fixed penalty, the charge depends on how late you're paying the taxes due. If you're only slightly delayed, the penalty will be much lower than if you're several months in arrears.
Who is Exempt?
Not all of us will have to go digital. HMRC realises that some people truly cannot use digital. If you cannot comply because you are of old age, disabled, or live in an area with poor internet reception, then you might get an exemption. Trustees and certain religious organisations are also out of the scope.
Partnerships are not included in the initial phase, although HMRC has said that they will be added to MTD in due time.
How You Can Prepare
If you're considering what to do next, the advice is to not wait until the last minute. The earlier you prepare, the simpler the process will be.
Start by looking to see if your earnings will place you in MTD for 2026. Even if you are below the threshold, it's a good idea to keep an eye on your numbers so that you can know what's approaching. If you're close to the threshold, it may be wise to plan as though you'll be in it.
The second thing is to think about how you will keep your records. Do you have accounting software already, or do you still do them on paper or simple spreadsheets? If you do, it is a good time to think about MTD-compatible software. There are plenty of software providers around, and many of them have simple, low-cost solutions for sole traders and landlords.
Voluntary registration is also an option. Even if you're not yet required to comply, registering ahead of time lets you get a head start and become comfortable with the system without the pressure of looming deadlines.
Finally, it's a good idea to sit down with your accountant or tax professional. They can inform you of what software will work best for you, based on your unique needs, and help set up processes that best fit your company.
Why Does This Matter?
You might think, "This is additional admin. Why is HMRC requesting this?" That's not an unreasonable question.
From HMRC's point of view, MTD is narrowing the "tax gap", i.e., the billions of pounds lost every year to errors and misdeclaration. By having taxpayers report information more regularly and digitally, HMRC have a clearer and more accurate view of taxable income.
From your perspective, even though the change may be inconvenient at first, there are some benefits. Having records on computer normally makes you more structured. The quarterly returns can allow you to see your position on tax more clearly through the year, rather than facing a big shock in January. And digital software can help reduce errors that would otherwise result in enquiries or fines.
Of course, it will not be easy to make the switch. For those who are technologically challenged, converting to software can be intimidating. There may also be costs in terms of buying or upgrading the software. But with proper planning and the right guidance, these can be overcome.
Conclusion
Making Tax Digital for Income Tax is not a small change; it's a whole new way of dealing with the tax system. From April 2026, if you're a sole trader or landlord earning over £50,000, this will be your reality. Over the next few years, the thresholds will fall and more individuals will be brought in.
The good news is that you can prepare. By working your way through your income, choosing proper software, and talking with your accountant, you can make sure that the transition is smooth rather than stressful.
So don't wait until 2026 catches you off guard. Start by getting used to the digital record-keeping, explore your software options, and think about how quarterly reporting could actually simplify keeping up with your books. Because if you're on board, you could find tax season much less taxing than it would be otherwise.
