MTD April 2026: Everything UK Landlords Need to Know

What is MTD for Income Tax?

Making Tax Digital (MTD) for Income Tax Self Assessment is an HMRC programme that replaces the annual Self Assessment tax return with a year-round digital system. Instead of completing one return each January, landlords and self-employed people affected by MTD must keep digital records throughout the year and submit quarterly updates to HMRC using HMRC-compatible software (gov.uk).

The government’s stated aim is to reduce the tax gap caused by errors in self-reported income. By moving to near-real-time reporting, HMRC expects landlords to have a clearer, more accurate picture of their tax position throughout the year rather than scrambling each January.

MTD for Income Tax is distinct from MTD for VAT, which has already been mandatory for VAT-registered businesses since April 2022. If you are already using MTD for VAT, you will need to take additional steps to comply with MTD for Income Tax — the two programmes use different software categories.

Who is Affected by MTD from April 2026?

The April 2026 phase applies to landlords and self-employed individuals whose qualifying income exceeds £50,000 per year. Qualifying income is the combined total of your gross rental income and your gross self-employment income — calculated before any allowable expenses are deducted.

For example, if you receive £35,000 in gross rent and earn £20,000 from freelance work, your qualifying income is £55,000, and you will be mandated from 6 April 2026.

If your qualifying income currently sits below £50,000 you will not be mandated in April 2026, but you may be caught by the April 2027 threshold if your income grows or if HMRC lowers the threshold further in future. It is worth understanding the rules now regardless.

Partnerships, trusts, and companies are not covered by the current MTD for Income Tax rules, which apply specifically to sole-name landlords and self-employed sole traders. Landlords who hold property jointly will need to check their individual share of rental income against the qualifying income threshold.

What You Need to Do Before 6 April 2026

If you are above the £50,000 threshold, there are three concrete actions to take before 6 April 2026.

1. Sign up for MTD for Income Tax

You must register with HMRC for MTD for Income Tax. You can do this through your Government Gateway account. HMRC has been running a voluntary pilot since 2018; mandation begins on 6 April 2026. If you are in the pilot already, your obligations become mandatory from that date.

2. Choose compatible software

You must use software that HMRC recognises as compatible with MTD for Income Tax. The software must be able to keep digital records of your income and expenses, and submit quarterly updates directly to HMRC via the MTD API. A list of compatible products is published on gov.uk (compatible software list). Spreadsheets can only be used if you also purchase HMRC-approved bridging software that handles the API submission on your behalf.

LandlordTaxAi is purpose-built for UK landlords and is working towards HMRC recognition for MTD for Income Tax. It automates the categorisation of rental transactions and prepares your quarterly figures, reducing the manual effort of compliance to a monthly review.

3. Start keeping digital records now

From 6 April 2026, digital record-keeping is mandatory. That means recording each rental income receipt and each allowable expense in your software at the time it occurs — not reconstructing 12 months of transactions in January as many landlords currently do with Self Assessment. Starting before April 2026 lets you identify gaps in your record-keeping before HMRC mandates it.

Quarterly Update Deadlines Under MTD

Under MTD for Income Tax you must submit four quarterly updates per tax year. Each update covers a three-month period of income and expenses. The deadlines are one calendar month and seven days after the end of each quarter.

After the four quarterly updates, you must submit an End of Period Statement (EOPS) for each property business and each self-employment source. The EOPS finalises any adjustments such as capital allowances or private use adjustments that cannot be included in a quarterly update.

Finally, you submit a Final Declaration — the MTD equivalent of the Self Assessment return — by 31 January following the end of the tax year. Your tax payment is also due by 31 January, alongside any payments on account due in July.

Penalties for Missing MTD Obligations

HMRC is introducing a points-based penalty system for late MTD submissions. Each missed quarterly update earns one penalty point. Points expire after a set period if you return to full compliance, but once you accumulate enough points a financial penalty is charged.

For quarterly filers the penalty threshold is four points, at which point a flat £200 penalty is imposed. Each subsequent missed filing while at the threshold earns an additional £200 penalty. The points system is designed to avoid punishing occasional lapses while still penalising persistent non-compliance.

Separately, late payment of tax continues to attract interest at HMRC’s standard rate, currently set at the Bank of England base rate plus 2.5 percentage points. Significant underpayments can also attract a separate late payment penalty of 5% of the tax outstanding.

The points-based system replaces the older fixed-penalty regime that applied under Self Assessment, where a £100 penalty applied automatically from day one of a late return.

What Software Do You Need for MTD for Income Tax?

Compatible software must meet HMRC’s functional standards, which include the ability to:

• Keep digital records of each income receipt and allowable expense
• Categorise income and expenses according to HMRC property income categories
• Submit quarterly updates to HMRC directly via the MTD API
• Submit the End of Period Statement and Final Declaration

General-purpose accounting tools such as spreadsheets do not meet these requirements on their own. If you prefer to use a spreadsheet, you will need bridging software that acts as the connection between your spreadsheet and the HMRC API. However, bridging software adds cost and complexity — purpose-built landlord tax software is generally a more straightforward route.

When choosing software, consider whether it handles multiple properties, supports joint ownership arrangements, and can import bank transactions automatically. Manual data entry across four submissions per year is error-prone and time-consuming.
