MTD for landlords: the practical version.

Making Tax Digital for Income Tax started for the first group of landlords and sole traders on 6 April 2026. The test uses qualifying income from the tax return two years before the year you are brought in, so the 2024-25 return for the April 2026 start. If gross property income held personally, plus any sole-trader income, was above £50,000 that year, the digital-record and quarterly-update duties apply. A portfolio that first crossed £50,000 in 2025-26 is not mandated from April 2026. Three things matter.

1. The threshold is gross income

The £50,000 test is on your total rental income before anything comes off. Not profit. Before mortgage interest, repairs, management fees and everything else.

A landlord with five Scottish properties at £1,000 a month in rent has £60,000 of gross rental income, even if the profit left at the end is a fraction of that. The number to test is the top line.

2. Limited company properties are outside the regime

MTD for Income Tax does not apply to property owned by a limited company. Company profits are taxed under Corporation Tax, which sits outside this system.

If everything you own sits in limited companies, and you only draw salary or dividends from them, MTD does not touch that property income at all. If you hold some properties personally and some through a company, the personal side is tested on its own. The personal rental income alone can be enough to take you over £50,000.

3. The threshold falls twice

Actual eligibility still depends on the prior-year qualifying-income test and any exemption or deferral that applies to the person.

The three obligations once you are in scope

First, digital records. Income and expenses recorded as they happen through the year, not rebuilt from bank statements at year end. A paper cashbook does not count.

Second, quarterly updates. Four per tax year, submitted through MTD-compatible software. Each one is cumulative: it restates the year to date, not just the last three months.

Third, your tax return, due by 31 January after the tax year ends, filed through your MTD software rather than HMRC's online service. That is where adjustments, allowances and reliefs are applied, your tax is calculated and the balance is paid. HMRC used to call this step the Final Declaration and once planned a separate End of Period Statement as well; neither term is in current HMRC guidance.

The quarterly updates are summaries of income and expenses. Nothing more. Tax is still calculated once a year, at the return, on the same 31 January deadline Self Assessment has always used. There are no penalties for a late quarterly update in 2026-27; from 2027-28 a points system applies, with a £200 penalty at four points.

The Scottish overlay

Scottish income tax rates sit on top of all this. For 2026-27 a Scottish landlord in the higher band pays 42% on rental profit, two percentage points more than the equivalent rate in England and Wales, and that band starts at £43,663 in Scotland against £50,271 elsewhere, which is the bigger practical difference. From 6 April 2027 the rest of the UK moves to separate property income rates, which closes the higher-rate gap. The quarterly rhythm has one upside: you see your tax bill building through the year, rather than meeting it cold in January.
