Making Tax Digital for Landlords: The Complete 2026 Guide

Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is no longer a future concern for UK landlords. As of April 2026, landlords and sole traders with qualifying income exceeding £50,000 must keep digital records and submit quarterly updates to HMRC using MTD-compatible software. If you earn rental income above this threshold, you need to act now.

This guide covers everything you need to know: who is affected, what the deadlines are, how quarterly submissions work, and how to avoid penalties. Whether you own one buy-to-let or manage a portfolio of twenty properties, the rules apply equally.

What Is Making Tax Digital for Income Tax?

MTD ITSA is HMRC's initiative to move the UK tax system fully digital. Instead of filing a single Self Assessment return at the end of the tax year, landlords must now submit income and expense summaries to HMRC every quarter throughout the year.

The goal is to reduce errors in tax returns and give both HMRC and taxpayers a clearer, real-time picture of tax liabilities. For landlords, this means keeping digital records of all rental income and allowable expenses as they occur, rather than scrambling to compile everything in January.

Who Needs to Comply with MTD ITSA?

You must comply with MTD ITSA if you are an individual landlord (not a limited company) and your total qualifying income from self-employment and/or property exceeds £50,000 per year. From April 2027, the threshold drops to £30,000.

Qualifying income for landlords means your gross rental income before deducting any expenses. If you own multiple properties, you add up all the rent received across your entire portfolio.

• April 2026: Mandatory for income over £50,000
• April 2027: Mandatory for income over £30,000
• Future years: HMRC may lower the threshold further

Limited companies are not currently within scope of MTD ITSA. They already fall under MTD for Corporation Tax, which has a separate timeline. Partnerships will be brought into MTD ITSA at a later date yet to be confirmed.

The Four Quarterly Submission Deadlines

Under MTD ITSA, the tax year is divided into four quarters. After each quarter ends, you have approximately one month to submit a summary of your rental income and expenses to HMRC.

• Quarter 1 (6 April – 5 July): Submit by 5 August
• Quarter 2 (6 July – 5 October): Submit by 5 November
• Quarter 3 (6 October – 5 January): Submit by 5 February
• Quarter 4 (6 January – 5 April): Submit by 5 May

After all four quarterly submissions, you must also complete an End of Period Statement (EOPS) and a Final Declaration, which replaces the traditional Self Assessment tax return. The Final Declaration deadline is 31 January following the end of the tax year.

What Do Quarterly Submissions Include?

Each quarterly update is a summary of your rental income and expenses for that period. You do not need to submit individual receipts or invoices — just the totals broken down into HMRC's standard categories.

For income, you report total rent received, any premiums for granting a lease, and other property income such as car parking or phone mast rental.

For expenses, HMRC uses standard categories including repairs and maintenance, insurance premiums, property management fees, legal and professional costs, utility bills (where the landlord pays), ground rent and service charges, travel costs for property management, and other allowable expenses.

The figures do not need to be precise to the penny at the quarterly stage. HMRC allows reasonable estimates in quarterly updates, provided you correct them in your End of Period Statement. However, keeping accurate records throughout the year saves significant time later.

What Software Do You Need?

You must use HMRC-recognised software that can connect directly to the MTD API. Spreadsheets alone are not sufficient — you need software that can digitally submit your quarterly updates, EOPS, and Final Declaration to HMRC.

LandlordGuru is fully MTD-compatible and connects directly to HMRC. It handles quarterly submissions, tax calculations, End of Period Statements, and Final Declarations, all from one platform. Because it is built specifically for landlords, the expense categories map directly to HMRC's property income categories, reducing the chance of errors.

Penalties for Non-Compliance

HMRC has introduced a points-based penalty system for late submissions. Each time you miss a quarterly deadline, you receive one penalty point. Once you accumulate a set number of points (currently four for quarterly obligations), you receive a £200 fine. Further late submissions within the same period of compliance each trigger an additional £200 penalty.

Late payment penalties also apply. If tax remains unpaid 15 days after the due date, a penalty of 2% of the outstanding amount is charged. After 30 days, an additional 2% is added. Beyond 30 days, a daily rate of 4% per annum applies to the outstanding balance. Read more about these penalties in our HMRC penalties guide.

How to Get Started

If your rental income exceeds £50,000, you should already be preparing. Here is a practical checklist:

1. Sign up for MTD-compatible software. LandlordGuru offers a free tier so you can get started without cost.
2. Register for MTD ITSA with HMRC. You need to opt in through your Government Gateway account.
3. Connect your software to HMRC. LandlordGuru uses secure OAuth to link to your HMRC account.
4. Start recording income and expenses digitally. Connect your bank via Open Banking to automate transaction imports.
5. Submit your first quarterly update. Your software will guide you through the submission process.

What About Landlords Below the Threshold?

If your rental income is below £50,000, you are not yet required to use MTD ITSA. However, there are strong reasons to adopt digital record-keeping voluntarily. You will gain a clearer picture of your finances, reduce the time spent on your Self Assessment return, and be ready when the threshold is eventually lowered to include you.

Many landlords with income between £30,000 and £50,000 are choosing to start now, given that the £30,000 threshold takes effect in April 2027. Getting a full year of practice with the quarterly submission cycle is valuable.

How LandlordGuru Makes MTD Simple

LandlordGuru was built from the ground up with MTD compliance at its core. Rather than bolting on HMRC connectivity as an afterthought, every feature — from expense categorisation to financial reporting — is designed to feed seamlessly into your quarterly submissions.

With Open Banking integration, your bank transactions are imported automatically and categorised against HMRC's property income categories. When submission time comes, your quarterly figures are already calculated. You review them, tap submit, and LandlordGuru sends everything directly to HMRC.

The platform also handles End of Period Statements and Final Declarations, so you can manage your entire MTD obligation from a single app without needing a separate accountant or additional software.
