MTD for joint property owners: whose income counts and who reports

Leah and Sam are fictional, but their situation is a common one. The two siblings inherited a terraced house from their parents and now let it together, sharing the rent equally. Sam also lets a small flat that is in his name alone. When they first read about Making Tax Digital (MTD) for Income Tax, they were not sure whether HMRC would look at the whole rent from the house, or whether one of them could simply take care of the reporting for both. This guide walks through how GOV.UK answers those questions.

Why the test looks at each owner’s own share

The starting point is always one person’s own income. GOV.UK puts the rule for shared property plainly: if you get income from a jointly owned property, your share of that property income counts towards your own qualifying income, before expenses. The same share is then added to any other property or self-employment income that belongs to that person, and the total is what HMRC compares with the threshold.

That matters because it means the whole rent from a shared property is never tested against one owner. Whether you need to use MTD for Income Tax depends on whether your own qualifying income is over the threshold for the relevant tax year. Two people who own the same house can therefore end up in different places, depending on what else each of them earns.

GOV.UK also covers a situation that catches some co-owners out, where an agent or the other owner only tells you what your share came to after costs. If you jointly own a property and only receive notice of your share of the income after expenses have been deducted, HMRC assesses that figure as your qualifying income.

Most joint owners split the rent in line with how they own the property, but that is not always the case for tax. HMRC’s Property Income Manual explains that for Income Tax, the share of property income that is yours depends on who receives or is entitled to the profits, and that does not automatically follow the shares of ownership. If your arrangement is unequal, or the rent is paid in a way that does not match the ownership, an accountant or tax adviser can help you settle which share is yours before you work out your figures.

A worked example with Leah and Sam

The figures in this section are an illustration only. They are not GOV.UK figures and do not describe any real person, but they show how the share rule plays out once you put numbers to it.

Suppose the terraced house brings in £36,000 a year in gross rent. With a 50% share each, Leah’s share is £18,000 and Sam’s share is £18,000. Leah has no other property or self-employment income, so her qualifying income is £18,000. Sam adds the £14,000 gross rent from his own flat, which brings his qualifying income to £32,000.

If those were their figures for the year HMRC tests, Sam’s income would be over the £30,000 threshold that applies from 6 April 2027, while Leah’s would be at or under every threshold in the current timeline, down to the £20,000 step from 6 April 2028. The house is the same and the rent is split the same way, yet the two siblings reach different answers, because the test is about each of them rather than about the property.

What each owner does once they are over the threshold

An owner who is brought into MTD keeps digital records and sends quarterly updates for their own property income, and a shared property is part of that. Your share of any jointly let UK properties forms part of your UK property business, so your software adds it to your other UK property records in one quarterly update. GOV.UK keeps the record-keeping separate as well: a landlord who jointly lets property only needs to create digital records for their own share of the income and expenses, and does not need to link those records to the other landlord's records. In Leah and Sam’s example, that means Sam records his half of the house alongside his flat, and he does not need Leah’s records to do it.

GOV.UK does not describe a way for one co-owner to send updates covering the other’s share, so it is safest to treat each owner’s position as their own. That is also why one owner being in MTD does not, by itself, bring the other owner in: each position is decided by that person’s own qualifying income, as Leah and Sam’s example shows.

The simpler rules HMRC allows for jointly let property

HMRC offers some easements for jointly let property, which can make the year easier when another owner or an agent handles the shared costs. As GOV.UK describes them today, there are two, and you can use either or both.

• You can create less detailed digital records for jointly let property: a single record for each category of property income in an update period, and a single record for each category of property expense in a tax year.
• In your quarterly updates you can choose to include either the income and expenses for jointly let property, or the income only.

The second option comes with a condition worth keeping in mind. If you leave out the expenses for jointly let property, you must report them after the end of the tax year, by resending your fourth quarterly update before you submit your tax return. It also only applies to the shared property. If you also own other property outright, your quarterly updates must still include both the income and the expenses for those properties. So Sam could send income-only figures for the house during the year, but his flat would still need both its income and its expenses in every update.

When the property is held through a partnership

Some families run a letting business as a formal partnership rather than simply owning a property together, and GOV.UK treats the two differently. Your share of profit from a partnership as an individual partner does not count towards your qualifying income, and you do not need to keep digital records or send quarterly updates for it. Partnerships will need to use MTD for Income Tax in the future, on a timeline HMRC has not yet set out. If you are not sure which of the two describes your arrangement, it is worth checking with an accountant before you work out your qualifying income.

Checking your own share in the calculator

The MTD threshold calculator has an ownership-share field for exactly this situation. Enter the gross rent from the shared property and your percentage, add any self-employment income of your own, and it works out your share and compares the total with each step in the timeline. The percentage applies to all the property income you enter, so if you also have property of your own, as Sam does, it is simpler to work out your share first, add your other rent to it, and enter that total at 100%. If you also hold property through a company, the guide to mixed property portfolios explains which income stays outside the personal test, and the main MTD guide covers the wider rules. Penalties are covered separately in the MTD penalties guide.
