MTD for jointly owned property: spouses and partners

If you own a rental property with your spouse, civil partner or anyone else, Making Tax Digital (MTD) for Income Tax treats each of you separately. Each owner counts only their own share of the rent towards the threshold, and each owner who is over it signs up and sends their own quarterly updates. Joint owners also get an easement: they can report income only during the year and add expenses afterwards.

Do joint owners each count the full rent?

No. HMRC’s qualifying income guidance, updated 11 September 2026, says your share of the property income counts towards your qualifying income. Its example is two siblings sharing £50,000 of rent equally: each has qualifying income of £25,000.

If you only learn your share after expenses have been taken off, for example from a managing co-owner, HMRC uses that figure.

Remember to add any other property or self-employment income you have. A spouse with £16,000 of joint rent and a £20,000 sole trade has £36,000 of qualifying income. Our qualifying income guide explains what to include.

How are spouses and civil partners taxed on joint property?

Spouses and civil partners who live together are taxed 50:50 on income from jointly held property by default. This is the rule in section 836 of the Income Tax Act 2007. HMRC’s manual at TSEM9842 says that “in the absence of a valid form 17 declaration, the 50/50 rule applies.”

The split that applies for tax is also the split that decides whether each of you is in MTD. Unmarried partners, siblings and friends are taxed on their actual share, and the 50:50 rule does not apply to them.

How does Form 17 change the split?

Form 17 lets a married couple or civil partners be taxed on their actual unequal shares. The rules come from section 837 of the Income Tax Act 2007.

• Both must sign. The declaration is joint. If one of you does not agree, the 50:50 rule stays.
• Your shares must really be unequal. HMRC asks for evidence, such as a declaration of trust or deed.
• Notice within 60 days. Under section 837, HMRC must receive notice within 60 days beginning with the date of the declaration.
• No backdating. The declaration applies to income arising on or after its date.

Our Form 17 guide covers the paperwork. A Form 17 split can move one spouse above the £30,000 threshold and the other below it, so check both figures before you send it.

What goes in a joint owner’s quarterly updates?

You can send your share of income only. HMRC’s quarterly updates guidance, updated 16 October 2026, gives joint owners two choices for jointly let property:

1. Income and expenses. Report your share of both in each update, like any other landlord.
2. Income only. Report your share of rent in each update and leave joint property expenses out.

If you choose income only, you must report the expenses after the tax year ends by resending your fourth update. For property you own alone, you must still include both income and expenses in every update.

The digital record keeping notice, updated 27 March 2026, goes further. A joint owner can keep one digital record for each category of property income in each quarterly period, and one record per expense category for the year. You do not need a digital entry for every rent receipt from the joint let.

Which applies to you?

• If your share is £30,000 or less and you have no other property or trading income, you do not join MTD in April 2027.
• If your share is over £30,000 on your 2025-26 return, you join from 6 April 2027.
• If only one spouse is over the threshold, only that spouse uses MTD. The other carries on with a normal Self Assessment return.
• If you also own lets alone, your sole and joint UK lets form one property business. Include expenses for the sole lets in every update. See MTD with multiple income sources.
• If a letting agent collects the rent, you are still the person taxed. See MTD and letting agents.

What joint owners should do now

1. Confirm the split. Check whether the 50:50 rule or a Form 17 applies, and use that share.
2. Work out each owner’s figure from the 2025-26 return, adding any other rent and self-employment turnover.
3. Agree who keeps the records. The income-only option works best when one owner collects the rent and tells the other their share each quarter.
4. Pick software that handles joint property, including the income-only option and resending the fourth update.

Frequently asked questions

Do both spouses need to sign up for MTD if they own a rental together?

Only those whose own qualifying income is over the threshold. Each spouse is tested on their share of the rent plus any other property and self-employment income.

Can one joint owner send quarterly updates for both of us?

No. Each owner in MTD sends updates for their own income, though either of you can authorise an agent to submit for you.

Do I have to include joint property expenses in each quarterly update?

No. You can report your share of income only and add the expenses after the tax year by resending your fourth update. Expenses for property you own alone must still go in each update.

Does Form 17 affect whether I need to use MTD?

Yes. Form 17 changes the share you are taxed on, which is the share counted towards qualifying income. It applies only to income arising after the declaration date.

Can unmarried couples use Form 17?

No. Form 17 is for married couples and civil partners who live together. Other joint owners are already taxed on their actual share.
