MTD ITSA: Which Landlords Need to Sign Up and When?

A landlord must sign up for Making Tax Digital for Income Tax if their qualifying income from property and self-employment combined exceeds £50,000, and that obligation started on 6 April 2026. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028, so a landlord outside the rules today may well be inside them within two years. The trigger is gross rent received, not taxable profit, which is why landlords with modest margins and large mortgages are being caught first. Making Tax Digital landlords 2026 obligations mean quarterly updates rather than a single annual return, and they apply to the individual rather than to each property. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, works with landlords across the UK on exactly this transition. This article sets out who is in scope, how qualifying income is measured, what has to be submitted and by when, and which landlords are exempt or deferred.

Key Takeaways

• Landlords with qualifying income above £50,000 have been within Making Tax Digital for Income Tax since 6 April 2026, with the threshold dropping to £30,000 in April 2027 and £20,000 in April 2028.
• Qualifying income is gross rental income before any expenses or mortgage interest, added to gross self-employment turnover, and is tested against the tax year two years earlier.
• An MTD ITSA landlord must file four quarterly updates due on 7 August, 7 November, 7 February and 7 May, plus a final declaration by 31 January after the tax year ends.
• Joint owners count only their own share of the rent towards the £50,000 threshold, so a couple sharing £70,000 of rent equally are each tested on £35,000.
• Income from furnished holiday lettings, rent-a-room and overseas property all counts as qualifying property income for the threshold test.
• Landlords must keep digital tax records of property income and expenses in MTD-compatible software, and spreadsheets alone are only acceptable when linked to HMRC through bridging software.

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

Any individual landlord whose qualifying income exceeded £50,000 in the 2024/25 tax year was mandated into Making Tax Digital for Income Tax from 6 April 2026. HMRC uses the tax return filed for the year two years before the start date, so entry into the regime is determined by figures already submitted rather than by current trading.

The rules apply to individuals and, from April 2027, to certain partnerships. Property held inside a limited company is outside MTD for Income Tax entirely, because company profits are reported through the corporation tax system. A landlord who owns two flats personally and a third through a special purpose vehicle is therefore in scope for the two personally held flats only.

Being in scope is not optional and there is no election to stay on the old system. HMRC writes to affected taxpayers, but the legal obligation sits with the landlord whether or not a letter arrives. For a full walkthrough of preparing a property business for the regime, see our guide to Making Tax Digital for landlords.

How is qualifying income calculated for a landlord?

Qualifying income is the gross income from property and self-employment added together, before deducting any expenses, mortgage interest or allowances. It is a turnover test, not a profit test, and that distinction is what pulls in landlords who make very little money.

Consider a landlord with two rental flats generating £34,000 of gross rent, who also does freelance consultancy turning over £19,000. Total qualifying income is £53,000. After £11,000 of letting costs, £14,000 of mortgage interest treated under the Section 24 restriction and £4,000 of consultancy expenses, the taxable profit is £38,000, because the restricted interest is not deducted in arriving at profit. The landlord is mandated, because £53,000 exceeds £50,000.

Rental income counted for the test includes UK property, overseas property and rent-a-room receipts. Income from employment, dividends, pensions and savings interest is excluded. Jointly owned property is split by beneficial ownership share, so a married couple receiving £70,000 of rent from jointly held property are each tested on £35,000 and neither is mandated in 2026/27, though both will be caught when the £30,000 threshold arrives in April 2027.

What does an MTD ITSA landlord actually have to submit?

An MTD ITSA landlord must submit four quarterly updates and one final declaration each tax year, replacing the single self-assessment return. The quarterly deadlines are 7 August, 7 November, 7 February and 7 May, and the final declaration is due by 31 January following the end of the tax year.

For 2026/27 that means updates on 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027, with the final declaration and the balancing payment both due on 31 January 2028. Payment dates have not changed and nothing is payable on a quarterly update.

A quarterly update is a cumulative summary of income and expenses by category for the year to date, not a tax calculation. Separate updates are required for each income source, so a landlord with a UK property business, an overseas property business and a sole trade files three sets of quarterly figures. Accounting adjustments, reliefs, capital allowances and the finance cost restriction are all handled at the final declaration stage, which is also where employment income, dividends and other untaxed income are added.

What records and software do landlords need?

Landlords within Making Tax Digital must keep digital tax records of property income and expenses in MTD-compatible software, with digital links carrying data through to HMRC. Paper receipts can still be kept as backup, but the underlying record of each transaction must be created and stored digitally.

Spreadsheets are not prohibited, but a spreadsheet on its own cannot file. It must be connected to HMRC through bridging software, and the data must flow across without manual retyping. Many landlords find dedicated property software simpler, particularly where multiple tenancies, agent statements and service charges are involved.

Jointly owned property carries a useful relaxation. HMRC allows joint owners to record their share of gross rent quarterly and defer the expense detail to the final declaration, which reduces the quarterly burden considerably for couples and family partnerships. Records must be retained for at least five years after the 31 January filing deadline.

Which landlords are exempt or deferred?

Exemption from Making Tax Digital for Income Tax is available on grounds of digital exclusion, and automatic exemptions apply to a small number of defined groups. Digital exclusion covers landlords who cannot use digital tools because of age, disability, location or religious belief, and it must be applied for and granted by HMRC rather than assumed.

Automatically exempt groups include trustees, personal representatives of deceased estates, and individuals without a National Insurance number. Landlords whose only property income falls under rent-a-room within the £7,500 allowance and who have no other qualifying income will not meet the threshold in any event.

Deferral is different from exemption. A landlord below £50,000 today is deferred rather than excused, and will join at £30,000 in April 2027 or £20,000 in April 2028. Because the test looks back two years, a landlord whose 2025/26 gross rent was £32,000 should be preparing now for a 2027 start date.

Frequently Asked Questions

Do I have to join Making Tax Digital if I only own one rental property?

Only if your qualifying income exceeds the threshold. A single rental property producing more than £50,000 of gross rent brings you into Making Tax Digital for Income Tax from 6 April 2026. If the rent is lower, you may still be caught once the threshold falls to £30,000 in April 2027 or £20,000 in April 2028, or if you also have self-employment income that pushes the combined total over the line.

Is the MTD threshold based on rental profit or gross rent?

Gross rent. The £50,000 test uses total income received from property and self-employment before deducting expenses, mortgage interest or allowances. A landlord receiving £55,000 of rent with £40,000 of costs and interest is mandated into Making Tax Digital for Income Tax despite a taxable profit of only £15,000.

How does Making Tax Digital work for jointly owned rental property?

Each joint owner is assessed on their own beneficial share of the rent, so a property producing £70,000 of rent split equally gives each owner £35,000 of qualifying income. HMRC also allows joint owners to report only their share of income in quarterly updates, with the expense detail added at the final declaration, which cuts the quarterly workload significantly.

What are the quarterly deadlines for landlords under MTD ITSA?

Quarterly updates are due on 7 August, 7 November, 7 February and 7 May each year, covering the quarters ending 5 July, 5 October, 5 January and 5 April. The final declaration is due by 31 January following the end of the tax year, alongside the balancing payment, so for 2026/27 the final declaration deadline is 31 January 2028.

Does Making Tax Digital apply to property held in a limited company?

No. Making Tax Digital for Income Tax applies to individuals. No start date has been announced for partnerships. A property company reports through corporation tax and files annual accounts and a CT600 instead, so a landlord who has incorporated a portfolio is outside the quarterly update regime for that property.

Can I still use a spreadsheet for my rental records?

Yes, provided the spreadsheet is linked to HMRC through bridging software and each transaction is recorded digitally. Manually retyping totals into a filing portal does not satisfy the digital links requirement. Many landlords with multiple tenancies find dedicated property software less error prone than a spreadsheet and bridging tool combination.

How Blue Tick Can Help

Blue Tick Accountants advises landlords on whether they are in scope for Making Tax Digital, how their qualifying income is measured across jointly held and personally held property, and which software suits the size and structure of their portfolio. Getting the record keeping right before the first quarterly update is far cheaper than correcting it afterwards, and the practice handles the quarterly submissions and final declaration in full for landlords who would rather not touch them. Head to our website and book a meeting now.

Conclusion

The £50,000 gross income threshold is the single figure every landlord needs to check, because it is measured on rent received rather than profit made and it is falling to £30,000 in April 2027. Work out your combined property and self-employment turnover for the relevant year, confirm your beneficial share of any jointly owned property, and choose compatible software well before the quarter you are mandated. Landlords who prepare early treat the quarterly update as a bookkeeping routine rather than a deadline crisis.
