Making Tax Digital for Income Tax Self Assessment (MTD ITSA) has applied to landlords with gross property and self-employment income above £50,000 since 6 April 2026, and the limit falls to £30,000 on 6 April 2027. Affected landlords must keep digital records of rent and expenses, send four quarterly updates a year through HMRC-compatible software, and check all details in a final declaration.
- Landlords with gross qualifying income above £30,000 in the 2025/26 tax year must join MTD ITSA from 6 April 2027.
- Qualifying income is measured before expenses, and for jointly owned property only your own share of the rent counts.
- Four quarterly updates are due each year, on 7 August, 7 November, 7 February and 7 May, followed by a final declaration by 31 January.
- Late quarterly updates carry no penalty points in 2026/27, but later tax years use a points-based system.
- Compatible software, a separate bank account for property income and consistent digital records are the best way to avoid errors.
For years, most landlords dealt with HMRC once a year. They collected statements and receipts, calculated profit from their lettings after the tax year ended, and filed a Self Assessment return before the January deadline. Making Tax Digital for Income Tax changes that pattern by asking landlords to record their figures digitally as they go and to report to HMRC every three months.
The first wave, covering people with qualifying income above £50,000, began in April 2026. The next wave starts on 6 April 2027, when the limit drops to £30,000. Many landlords with a small portfolio of rental properties sit in the £30,000 to £50,000 range, so this second phase will likely affect them.
This guide explains who must comply in 2027, how to record income and expenses, which deadlines matter, how penalties work, and what practical steps landlords can take now so the first update in August 2027 feels routine, not rushed.
What Is MTD ITSA for Landlords?
MTD ITSA is part of the government’s long-running plan to move tax reporting online. Instead of one annual summary prepared after the event, landlords keep a running digital record of rental income and allowable expenses, which are the costs that can legitimately be deducted when calculating taxable profit. Every quarter, that record is turned into a summary and sent to HMRC from software that connects directly to its systems.
The aim is fewer errors, earlier visibility of what is owed and less of a scramble in January. HMRC does not supply the software, so each landlord must choose a compatible product from the official list.
When Do Landlords Need to Comply With MTD ITSA?
Whether you are in scope depends on your qualifying income, which means your gross income from self-employment and property before any costs are taken off. The limit is being lowered in stages:
- 6 April 2026: qualifying income above £50,000
- 6 April 2027: qualifying income above £30,000, based on your 2025/26 tax return
- 6 April 2028: qualifying income above £20,000, based on your 2026/27 tax return
HMRC uses the figures on your Self Assessment return to decide whether you fall in scope, so it is worth looking closely at your 2025/26 return. Income from a job taxed under PAYE, pensions and dividends does not count towards the limit. Landlords below the threshold can choose to sign up voluntarily, which is a useful way to practise before the rules become compulsory.
How to Work Out Your Qualifying Income
The key point is that qualifying income is turnover, not profit. Suppose a landlord receives £36,000 in rent during 2025/26 and spends £14,000 on repairs, insurance and agent fees. Their taxable profit is much lower, but their qualifying income is still £36,000, so they are in the April 2027 group.
Several details can change the answer:
- Only property held in your own name counts. Rent received by a limited company is not part of your personal figure.
- If you also run a self-employed business, add the gross income from both sources together.
- Lodger income is ignored up to the Rent a Room allowance, so it does not always count.
Checking this number early removes the guesswork and tells you whether you need to act this winter.
Special Scenarios for Landlords
Some situations need extra attention when planning for MTD ITSA.
Joint ownership
Each owner is assessed individually, and only their own share of the rent counts towards the limit. If a property earns £60,000 a year and is split equally, each owner has £30,000 of qualifying income. HMRC has also allowed jointly owned property to be reported with expenses submitted once a year rather than every quarter, although the rent itself still needs to be reported quarterly. Because guidance can change, confirm the current position before relying on it.
Mixed income
A landlord who also has a self-employed business combines both gross figures when checking the threshold. Different income sources are reported separately inside the same software.
Exemptions
Some people cannot reasonably use digital tools, for example because of age, disability, a remote location or religious belief. They can ask HMRC for an exemption, but it has to be agreed in advance and should never be assumed.
Key Income Reporting Requirements for Landlords
Digital records need to cover several areas:
- Rental income: all rent received, plus any other income linked to the property, such as retained deposits that cover damage.
- Allowable expenses: repairs and maintenance, insurance, letting agent and management fees, legal and professional costs, and utilities or council tax the landlord pays.
- Property details: the address of each property and, where useful, tenancy dates and periods when it stood empty.
Create records from the start of the accounting period and keep them for the usual period after the filing deadline, generally at least five years. It also helps to attach a digital copy of each receipt or invoice to the matching entry, because an expense without evidence is difficult to defend if HMRC asks questions.
One point catches many landlords out. Mortgage interest on a residential let is not deducted as an ordinary expense. HMRC treats it separately as a tax reduction, so you should not mix it with repairs and running costs. Likewise, improvements that add lasting value, such as an extension, are treated differently from routine repairs.
Key MTD ITSA Dates and Deadlines for Landlords
Every year, HMRC expects your quarterly updates on four fixed dates: 7 August, 7 November, 7 February and 7 May. By default, your reporting periods follow the tax year and begin on 6 April. If you prefer, you can switch to calendar quarters in your software, which end on 30 June, 30 September, 31 December and 31 March. Whichever option you pick, the filing dates do not move.
For landlords joining in April 2027, the timetable looks like this:
- First update: 7 August 2027
- Second update: 7 November 2027
- Third update: 7 February 2028
- Fourth update: 7 May 2028
- Final declaration: 31 January 2029
For landlords who entered MTD in April 2026, three updates remain for the 2026/27 year: 7 November 2026, 7 February 2027 and 7 May 2027. Their final declaration is then due on 31 January 2028. Because every update reports figures from the start of the tax year, the totals grow with each submission.
Step-by-Step Guide to Getting Ready
A simple plan spreads the workload across the winter:
- Check your 2025/26 return and add up gross property and self-employment income to see whether you pass £30,000.
- Make sure you have a Government Gateway account, as you need it to sign up.
- Choose compatible software that supports property income, quarterly updates and the final declaration.
- Enter each property and set up expense categories that match HMRC’s headings.
- Connect your bank feed so it imports transactions automatically.
- Practise before April 2027 by entering several months of real data and reviewing the quarterly summary.
- Diarise the four deadlines and set reminders a week ahead.
MTD ITSA Penalties for Landlords
HMRC has confirmed a gentler start for the first group. During 2026/27, late quarterly updates will not earn penalty points. After that, the points system applies. Each missed quarterly update or late final declaration adds a point, and reaching four points triggers a £200 penalty, with further penalties if deadlines continue to be missed.
Late payment is treated separately, with charges that grow the longer tax remains unpaid, so an on-time update does not excuse late payment. Landlords joining in April 2027 start in the 2027/28 tax year, so the points system applies from their first quarter.
Choosing Compatible Software
Look for software that supports quarterly updates and the final declaration, imports bank transactions, stores receipts digitally, and produces clear reports. Products such as Xero, FreeAgent and Landlord Studio are widely used by landlords, but always confirm on HMRC’s official list that a product is approved for MTD for Income Tax before you commit.
Spreadsheets can still be used, but only when bridging software links them to HMRC. Copying figures across by hand does not meet the digital link rules.
Final Thoughts
MTD ITSA is no longer something to think about in the distant future. It is already part of the UK tax system for landlords earning over £50,000, and the £30,000 threshold arrives on 6 April 2027. Landlords who prepare early will find the change much easier than those who wait until the first deadline approaches. Reliable digital records, suitable software and a clear view of the calendar are the foundations of compliance. With penalty points applying from 2027/28, building a quarterly routine now is a practical way to protect your income from avoidable charges.
