Making Tax Digital for Landlords: Complete UK Guide

Making Tax Digital for Income Tax reaches landlords in three stages, and which stage you fall into depends on your gross rent rather than on how many properties you own or how much profit you make. This guide sets out who is affected, how the income is measured, how jointly held property works and what the quarterly cycle looks like in practice.

Which landlords are affected

It applies to landlords who are registered for Self Assessment and receive property income above the threshold for the year being tested. That includes buy to let, houses in multiple occupation, long residential lets, commercial lets and short lets such as holiday lets and serviced accommodation. The furnished holiday lettings regime has ended, so short lets now sit alongside the rest of your property income.

Property held through a limited company is outside this entirely. A company pays Corporation Tax and files company accounts and a CT600, and none of that is affected by Making Tax Digital for Income Tax.

Non residents are treated differently. If you were not UK tax resident, foreign property income and self employment income not declared on your UK return are left out of the qualifying income test.

Qualifying income for a landlord

Qualifying income is gross rent, before any expenses, added to any gross self employment turnover you have. It is tested against the Self Assessment return you have already filed for an earlier year.

Because the figure is gross, the mortgage is irrelevant to the test. A landlord with £26,000 of rent and £24,000 of mortgage interest and costs has £26,000 of qualifying income, which is over the £20,000 line that applies from April 2028 even though the profit is small. A single well let property in London or the South East can be enough on its own at that stage.

Rent a room income and income within the £1,000 property allowance still form part of gross property income. Check the gross figure, not the taxable one.

Jointly owned property

Only your share of the property income counts towards your qualifying income. If a jointly held property produces £50,000 of rent and you are entitled to half, your qualifying income from it is £25,000. Where you are only told your share after expenses have been taken off, as happens with some arrangements, HMRC assesses that net figure instead.

Each owner keeps their own records and sends their own quarterly updates, because each owner has their own property business for tax. There is a relaxation on the expenses side for jointly held property, so the expense detail does not have to be duplicated in full by every owner in every quarter, with the position brought together at the final declaration.

One thing to settle before you start. Spouses and civil partners who hold property jointly are treated as owning it equally for tax, unless the beneficial ownership really is different and a declaration has been made to HMRC. If your returns have been splitting rent unequally without that, fix it before the split is locked into quarterly reporting.

Digital record keeping for a property business

Records have to be kept digitally as income and expenses arise, in software that can send data to HMRC. For a landlord that normally means four things. A bank feed from the account the rent arrives in. Agent statements entered as they come rather than at the year end. Receipts and invoices captured digitally and attached to the entry. And a record per property, so you know which property a cost belongs to even though the quarterly update covers the property business as a whole.

Recording by property is not strictly required by the quarterly update, but it is the difference between a set of records you can make decisions from and a single pot of numbers. It also makes the final declaration far quicker, because finance costs, repairs and voids can be seen property by property.

Categories matter too. Rent, other property income, repairs and maintenance, finance costs, legal and professional costs, cost of services provided including wages, and other allowable property expenses are reported separately. Coding as you go is much easier than reclassifying a year's worth of entries in April.

The quarterly cycle

The updates are cumulative, which is why each period above starts on 6 April. A figure corrected in a later quarter is simply corrected. The update is a summary of income and expenses by category and it is not a tax calculation, so no tax falls due on it.

The final declaration after the year end is where the real work sits. The finance cost credit is calculated, reliefs are applied, other income is added, and the tax is worked out and paid. It is due by 31 January, the same date the Self Assessment return is due now, and it replaces that return.

Landlords with more than one income source

Property and self employment are separate businesses for reporting. A landlord who also trades sends an update for the property business and an update for the trade, from the same software, by the same deadline. UK property and overseas property are also reported separately from each other.

This is where the combined qualifying income test bites. Someone with £17,000 of rent and £15,000 of consultancy turnover has £32,000 of qualifying income and joins in April 2027, with two sets of quarterly updates from the start.

Choosing software

You need software that HMRC recognises for Making Tax Digital for Income Tax, and the list of recognised products is published on GOV.UK and changes as more are approved. The questions worth asking are whether it handles property by property records, whether it connects to your bank, whether it captures receipts, and whether it handles jointly held property if that applies to you. A bridging tool that sits on top of a spreadsheet can satisfy the rules but it does not give you records you can use.

Whatever you choose, start before you have to. Running digital records for a year while you are not yet required to file quarterly is the cheapest preparation available.

Penalties and exemptions

Late submission is points based. A point for each missed deadline, a £200 penalty at four points and another £200 for each further miss. There are no penalties for missed quarterly updates in the 2026 to 2027 tax year. Late payment penalties and late payment interest are separate charges on the tax itself.

Exemptions exist, including for people who are digitally excluded. Anyone exempt still has to report their property income on a Self Assessment return in the usual way. If you think an exemption applies to you it is worth checking rather than assuming, because the obligation does not pause while you decide.
