How to Stay MTD Compliant
as a UK Property Investor

By My Property Organiser  ·  1 April 2026  ·  10 min readInvestor

Making Tax Digital for Income Tax Self Assessment is now live. From 6 April 2026, any UK landlord earning more than £50,000 in gross rental income must maintain digital records and submit quarterly updates to HMRC through approved software. Non-compliance carries real financial penalties, and the window to get organised has closed.

⚠️ Now live. MTD for Income Tax launched on 6 April 2026 for landlords earning £50,000+ gross. My Property Organiser is HMRC-approved and handles everything automatically.

What MTD for Income Tax requires

MTD replaces the single annual Self Assessment return with quarterly digital updates. You are required to maintain digital records of all rental income and allowable expenses as they occur, not reconstructed at year end. You must submit four quarterly updates to HMRC through approved software and complete an end-of-year finalisation that replaces the Self Assessment return. Critically, spreadsheets alone do not qualify. The software must connect directly to HMRC's Making Tax Digital API.

This is not an administrative inconvenience. It is a statutory obligation with financial consequences for landlords who miss deadlines or submit inaccurate records. The good news is that with the right platform in place, the entire compliance process can be largely automated.

The thresholds you need to know

  • From 6 April 2026: Landlords earning over £50,000 gross rental income
  • From 6 April 2027: Those earning between £30,000 and £50,000
  • From 6 April 2028 (proposed): Those earning between £20,000 and £30,000

The £50,000 threshold applies to gross rent received, not profit. A landlord receiving £52,000 in rent with £40,000 in costs is still in scope. If you are close to the threshold, any rent increase or new acquisition during the year could bring you in mid-year. It pays to check your position now rather than discover you are in scope when a quarterly deadline is already approaching.

Quarterly submission deadlines

  • Quarter 1 (Apr to Jun): due 5 August
  • Quarter 2 (Jul to Sep): due 5 November
  • Quarter 3 (Oct to Dec): due 5 February
  • Quarter 4 (Jan to Mar): due 5 May

Each quarterly update must include your income and expenses for that period. The figures do not have to be final at the time of submission, but they must reflect actual transactions recorded digitally throughout the quarter. Estimating figures after the fact is no longer acceptable practice under the digital records requirement.

What are the penalties for non-compliance?

HMRC uses a points-based penalty system. Each missed submission earns one penalty point. At four accumulated points a flat £200 penalty applies, with further charges for continued non-compliance. Separate interest charges apply to any tax paid late. The first year carries a soft-landing approach from HMRC focused on education, but the obligation to submit is not waived and points still accumulate.

For landlords with multiple properties or multiple income sources, the risk of losing track of quarterly deadlines is real. The solution is not a better calendar reminder. It is a platform that tracks your obligations automatically and tells you when action is required.

What allowable expenses must be recorded digitally?

The categories of allowable expense remain the same under MTD. The difference is that they must now be recorded digitally as they occur. Key categories include mortgage interest (restricted to basic-rate relief for higher-rate taxpayers), letting agent fees, maintenance and repairs, landlord insurance, legal and accountancy fees related to the property, and utility bills paid by the landlord. Capital improvements are generally not deductible as a revenue expense but may reduce a future Capital Gains Tax liability on disposal.

Keeping digital records throughout the year rather than reconstructing them before a deadline produces better data, better deductions and fewer errors. Landlords who switch to automatic transaction categorisation via Open Banking typically find that their expense records are more complete and more accurate than they were under their previous manual system.

How to become MTD compliant in four steps

Step 1: Confirm you are in scope

Add up your total gross rental income across all properties for the current tax year. If it exceeds £50,000, you are in scope now. Check this figure against all your rental income streams, including furnished holiday lets and any rent received from commercial property if applicable.

Step 2: Choose HMRC-approved software

HMRC maintains a published list of recognised MTD software providers. My Property Organiser is fully approved and submits quarterly updates directly from your live portfolio records. There is no CSV export, no bridging tool and no manual re-entry required.

Step 3: Connect your bank accounts via Open Banking

Open Banking integration pulls your rental income and expenses automatically, categorises them against your properties, and keeps your records current throughout the quarter. This eliminates end-of-quarter scrambles and ensures every submission is based on real transaction data rather than estimates.

Step 4: Set your quarterly calendar

Build the four quarterly deadlines into your calendar and ensure your records are being maintained throughout each quarter. My Property Organiser sends reminder notifications automatically as each deadline approaches, so nothing slips through.

How My Property Organiser handles MTD automatically

My Property Organiser was built with MTD compliance as a core function, not a bolt-on feature added after the fact. When you connect your bank accounts, the platform automatically categorises transactions against your properties. Before each quarterly deadline, you review the categorised records, make any necessary corrections, and submit with a single click. The platform generates the submission file and sends it directly to HMRC through the official API connection.

No accountant required for the compliance piece. Your accountant stays focused on tax strategy, not data entry. MTD submissions are handled by the platform from your live, bank-connected records, freeing up the professional relationship for the conversations that actually move your financial position forward.

How MPO compares to other MTD options

Several landlord tools claim MTD compliance but rely on manual data entry, CSV imports or bridging software to reach HMRC. Landlord Vision, Landlord Studio and most basic accounting tools offer parts of the compliance picture but none combine HMRC-approved MTD submission with AI-powered portfolio intelligence, Open Banking and document management in a single platform. With My Property Organiser, compliance and strategy live in the same dashboard, and your quarterly submissions are a byproduct of maintaining good records rather than a separate administrative task you have to schedule.
