MTD Joint Property Landlords: 2026/27 Rules for Jointly Owned Rentals

The core rule: MTD follows the owner, not the property

For MTD Income Tax, each joint landlord is assessed separately. One owner can be inside MTD while the other remains outside it, even though they own the same rental property.

That happens because the threshold is based on each person’s qualifying income: their gross income from self-employment and property before expenses, allowances or tax reliefs. For a jointly owned property, that normally means your share of the gross rent, not the whole rent from the property.

HMRC’s property income manual also makes the personal responsibility point clear: joint owners should know who keeps the records and have access to them, but each owner remains responsible for reporting their own share.

MTD thresholds for joint property landlords in 2026/27

MTD Income Tax is being introduced in phases. The first compulsory year is 2026/27 for individuals with qualifying income over £50,000, based on the 2024/25 tax return HMRC uses for the look-back test.

The threshold then drops to over £30,000 from 6 April 2027 and over £20,000 from 6 April 2028. The test is based on gross income, so mortgage interest, repairs, letting agent fees and insurance do not reduce the figure for MTD threshold purposes.

For joint landlords, the key calculation is: your share of UK property income, plus your foreign property income if relevant, plus your self-employment income. Employment income taxed under PAYE is not part of qualifying income.

How to split rental income and expenses between joint owners

Where jointly owned property is not a partnership, HMRC says each owner’s share of profit or loss will normally follow their share of ownership. Joint owners can sometimes agree a different division, but the tax split must match the split actually agreed and supported by evidence.

For spouses and civil partners living together, there is a special default rule: income from jointly owned property is normally taxed 50:50. If the couple want to be taxed on unequal actual beneficial interests, they usually need HMRC Form 17 and evidence such as a declaration or deed. We cover this in more detail in splitting rental income between spouses with Form 17.

MTD does not change the underlying tax split. It changes how each person keeps records and reports the figures. If your true ownership or income split is wrong in the software, every quarterly update and the final tax return can be wrong too.

• Unmarried co-owners usually report their agreed or beneficial share.
• Married couples and civil partners normally start from a 50:50 income split.
• A different spouse or civil partner split generally needs unequal beneficial ownership and Form 17.
• Each owner should keep evidence showing why their declared share is correct.

Digital records and quarterly updates for jointly let property

A joint landlord who is in MTD must use compatible software to keep digital records and send quarterly updates to HMRC. Quarterly updates are summaries, not tax returns, and HMRC does not receive each individual receipt or invoice.

HMRC has added easements for jointly let property. For their share of jointly let income, an eligible person can create one digital record for each property income category received during the quarterly update period. For their share of jointly let expenses, they can create one digital record for each property expense category incurred during the tax year.

There is also a simplified categorisation easement where annual turnover from self-employment or UK property is below the VAT registration threshold, currently £90,000. But residential property finance costs, such as mortgage interest, still need to be recorded and sent separately.

What if one joint owner is in MTD and the other is not?

This will be common in 2026/27. For example, one spouse may have rental income plus self-employment income over £50,000, while the other has only a smaller rental share. The first owner must use MTD from 6 April 2026; the second may continue under normal Self Assessment until they cross a later threshold.

Operationally, you still need one clean set of shared property records. The MTD owner then needs software that can report only their share. The non-MTD owner still needs enough records to complete their Self Assessment return accurately.

A letting agent, bookkeeper or spouse can help keep the records, but that does not transfer the legal reporting responsibility. If an accountant submits for you, make sure the agent authorisation is set up for the correct taxpayer, not just for the couple as a household.

• Use one shared source of truth for rents, expenses and finance costs.
• Tag each transaction to the correct ownership split.
• Keep evidence for unusual splits, one-off contributions and reimbursements.
• Check whether each owner needs their own software login, agent access or MTD sign-up.

Joint ownership is not automatically a property partnership

HMRC says joint letting does not, by itself, create a partnership. Most joint landlords simply include their share of the jointly owned property business in their personal property income.

A true property partnership is different. If the letting activity is carried on in partnership, the partnership profit or loss must be kept separate from personal property income, and different reporting rules can apply. HMRC has said partnerships will need to use MTD Income Tax in the future, but the timeline is still to be set out.

If you actively run a property business with non-family co-owners, a formal agreement, shared bank account, business name or partnership accounts, read MTD property partnerships for landlords and take advice before assuming the normal joint ownership treatment applies.

Step by step

1. 1

   Confirm the ownership and income split

   Check whether the property is owned 50:50, in unequal beneficial shares, or under a different agreed split. Married couples and civil partners should check whether the default 50:50 rule or a valid Form 17 position applies.

2. 2

   Calculate each owner’s qualifying income

   For each person, add their share of gross property income to any self-employment income. Do this before deducting expenses, mortgage interest, allowances or losses.

3. 3

   Check the correct MTD start date

   Use the phased thresholds: over £50,000 for 6 April 2026, over £30,000 for 6 April 2027 and over £20,000 for 6 April 2028.

4. 4

   Set up digital records by owner share

   Use software or a compliant digital process that records rents, expenses and finance costs and allocates each item to the correct owner share.

5. 5

   Submit separate quarterly updates where required

   Each owner who is in MTD must send their own quarterly updates and then complete their MTD tax return by 31 January after the tax year.

A worked example

Alex and Priya jointly own two buy-to-let properties 50:50. The properties produce £72,000 of gross rent in 2024/25. They also have £18,000 of allowable running expenses and £12,000 of residential mortgage interest. Priya also has £20,000 of self-employment income; Alex has no self-employment income.

Priya is over the £50,000 threshold and must use MTD from 6 April 2026, assuming these are the figures on the relevant 2024/25 return. Alex is not in the first wave because his qualifying income is £36,000, but he may join from 6 April 2027 if his relevant 2025/26 qualifying income is over £30,000. The expenses and mortgage interest matter for taxable profit, but not for the MTD threshold test.
