Making Tax Digital Penalties: What Landlords Risk If They Do Not Comply

Landlords who fail to comply with Making Tax Digital for Income Tax face a points-based late submission penalty, with a £200 charge triggered once four points are accrued in a rolling period, plus separate late payment charges and interest on any tax paid after the due date. Making Tax Digital for landlords has been live since 6 April 2026 for anyone with qualifying income above £50,000, and the obligations it creates are quarterly rather than annual, which means there are now five ways a year to fall foul of HMRC instead of one. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, is finding that most landlords understand the software requirement but underestimate how quickly small missed deadlines compound. This guide sets out who is in scope, what the deadlines are, how the penalty regime works, and what non-compliance actually costs a typical buy-to-let landlord.

Key Takeaways

• Making Tax Digital for Income Tax applies to landlords with qualifying income above £50,000 from 6 April 2026, above £30,000 from 6 April 2027 and above £20,000 from 6 April 2028.
• Qualifying income is gross rent before expenses, not profit, so a landlord receiving £54,000 in rent and making £40,000 of profit is in scope.
• Quarterly updates are due on 7 August, 7 November, 7 February and 7 May, with a final declaration by 31 January following the end of the tax year.
• Late submission penalties are points-based: each missed obligation earns one point, and reaching four points in a rolling period triggers a £200 penalty, with a further £200 for every later failure.
• Joint owners count only their own share of rent when testing the £50,000 threshold, so a couple splitting £80,000 of rent equally are each below it.
• Late payment charges and interest apply separately from late submission penalties, so a landlord can be penalised twice for the same tax year.

Which landlords are inside Making Tax Digital for Income Tax in 2026/27?

Making Tax Digital for landlords applies from 6 April 2026 to anyone whose qualifying income exceeded £50,000, tested on the 2024/25 tax return. The threshold falls to £30,000 from 6 April 2027 and to £20,000 from 6 April 2028, so most landlords with more than one property will be inside the regime within three years.

Qualifying income is measured gross. It is total rent received plus any sole trade turnover, before deducting mortgage interest, letting agent fees, repairs or any of the other costs a landlord can set against rental income. A landlord with £54,000 of rent and £14,000 of expenses has qualifying income of £54,000, not £40,000. Joint owners count only their own share, which is why a jointly held portfolio can sit outside the regime while a solely held one of the same size sits inside it. Once inside, you stay inside even if income later falls, unless HMRC agrees an exemption.

What deadlines must a landlord now meet?

Landlords inside MTD ITSA must keep digital records of rental income and expenses and submit four quarterly updates, due on 7 August, 7 November, 7 February and 7 May, followed by a final declaration by 31 January after the tax year ends. For 2026/27, that means the first update was due 7 August 2026 and the final declaration is due 31 January 2028.

Each of those five submissions is a separate obligation with its own penalty exposure. Quarterly updates are cumulative summaries of digital records rather than tax calculations, so they are quick to produce if the records exist and impossible to produce if they do not. The final declaration replaces the old self-assessment return and is where reliefs, adjustments and the Section 24 finance cost reducer are applied. Our guide to preparing a property business for quarterly reporting covers the software and record-keeping side in detail.

What penalties apply if a landlord misses a quarterly update?

Late submission penalties under Making Tax Digital work on a points system rather than an immediate fine. Each missed submission deadline earns one penalty point. For quarterly obligations, the threshold is four points, and reaching it triggers a £200 penalty. Every further missed deadline while at the threshold triggers another £200.

Points are not permanent. They expire after 24 months if the threshold is not reached, and once at the threshold they can be cleared by submitting on time for a set period and bringing all outstanding submissions up to date. The design is deliberate: it targets persistent non-compliance rather than a single missed deadline, which is a meaningful improvement on the old £100 automatic penalty for a late tax return. It also means a landlord who drifts for a full year reaches the threshold precisely as the fourth quarter falls due.

What happens if a landlord pays their tax late?

Late payment charges are entirely separate from late submission penalties and are calculated on the tax outstanding rather than on missed deadlines. A first charge arises once payment is a set number of days overdue, a second charge accrues while the debt remains unpaid, and late payment interest runs from the due date until the balance is cleared.

Because the two regimes are independent, a landlord who submits everything on time but pays late is penalised, and a landlord who pays on time but submits late is also penalised. Setting money aside monthly against the eventual January liability is the simplest protection, and it is far easier to do when quarterly updates are giving a running view of profit rather than a single annual reckoning.

Worked example: what non-compliance costs a landlord with £54,000 of rent

Consider a landlord with £54,000 of gross rent for 2026/27, £14,000 of allowable expenses excluding finance costs, and £9,000 of mortgage interest. Rental profit is £40,000. With no other income, £12,570 is covered by the personal allowance, leaving £27,430 taxed at 20%, which is £5,486. The Section 24 reducer gives 20% of the lower of finance costs, property profits and adjusted income above the allowance, so 20% of £9,000, reducing the bill by £1,800. Tax due is £3,686, payable by 31 January 2028. Rental income carries no National Insurance.

Now assume the landlord ignores MTD entirely and misses all four quarterly updates. Four points reaches the threshold, giving a £200 penalty. Missing the final declaration adds a further £200. That is £400 of avoidable penalties on a £3,686 tax bill, close to 11% of the tax itself, before any late payment charge or interest on the tax. None of it buys anything. The full picture of how the underlying tax is calculated is set out in our guide to tax on rental income.

How can landlords avoid MTD penalties?

The reliable protection is a bookkeeping routine that runs monthly rather than annually. Choose HMRC-compatible software before the quarter you need it, connect the bank account that receives rent, categorise transactions as they arrive, and diarise the four quarterly dates alongside 31 January. Landlords with agents should confirm in writing who is responsible for each submission, because appointing an agent does not transfer the legal obligation.

Landlords below the current threshold should still watch the £30,000 and £20,000 dates, and should check qualifying income against gross rent rather than profit. The move from an annual self-assessment return to five submissions a year is a change of habit more than a change of difficulty, and the landlords who struggle are those who leave the habit until the first penalty point lands.

Frequently Asked Questions

What is the penalty for missing a quarterly MTD update as a landlord?

Missing a quarterly update earns one penalty point rather than an immediate fine. Reaching four points in a rolling period triggers a £200 penalty, and every further missed deadline at the threshold adds another £200. Points expire after 24 months if the threshold is never reached, so a single missed quarter is not itself costly.

Do I have to comply with Making Tax Digital if my rent is under £50,000?

Not yet. Landlords with qualifying income above £50,000 joined from 6 April 2026, above £30,000 from 6 April 2027, and above £20,000 from 6 April 2028. Qualifying income is gross rent before expenses, so test it against total rent received. Joint owners count only their own share of the rent.

Does using a letting agent mean I am compliant with MTD?

No. The legal obligation to keep digital records and make quarterly updates rests with the landlord, not the agent. An agent or accountant can make submissions on your behalf, but penalties for missed deadlines fall on you. Agree in writing exactly which submissions your agent will handle and by when.

Can MTD penalty points be removed?

Yes. Points expire automatically 24 months after they are issued, provided the penalty threshold was never reached. Once at the four-point threshold, points are cleared by meeting every submission deadline for a set period of compliance and by bringing all outstanding submissions up to date. Paying a £200 penalty does not by itself reset the points.

Are late payment charges the same as late submission penalties?

No. They are two independent regimes. Late submission penalties are points-based and relate to missed filing deadlines. Late payment charges are calculated on unpaid tax and escalate the longer the debt remains outstanding, with interest running from the due date. A landlord can incur both in the same tax year.
