Landlords have a more complex MTD position than most sole traders. because rental income has its own specific rules, joint ownership creates individual obligations for each co-owner, and the April 2025 abolition of Furnished Holiday Let status changed the threshold calculation for thousands of property owners who had not anticipated it.
This guide covers exactly which rental income counts, how joint property splits work in practice, what the FHL abolition means for your threshold, and what you need to do before your first quarterly deadline.
The qualifying income for landlords is gross UK property rental income. the total rent received before any expenses are deducted. Mortgage interest, letting agent fees, repairs, insurance and management costs all reduce your taxable profit, but they do not reduce your qualifying income for threshold purposes.
This is the change that caught the most landlords by surprise. Before 6 April 2025, FHLs had special tax status and were treated as trading income for many purposes. From 6 April 2025, HMRC abolished the FHL regime entirely. FHL income is now ordinary UK property income in every respect.
The MTD consequence is direct: FHL income that was previously not counted in the same pool as buy-to-let rental income now counts in full. If you have a mix of FHL and standard rental properties, your total qualifying income is the gross rents from all of them combined.
This is the most misunderstood aspect of MTD for property owners. Many couples assume that because they share a property, they share a single MTD obligation. That is not how it works.
Each co-owner is assessed individually on their own share of the rental income. The thresholds are never pooled. Each person has their own MTD status, their own registration, and their own quarterly submissions.
Based on a property generating £104,000 gross rental income, owned 50/50. Both partners exceed the £50,000 threshold and must register and file separately.
Married couples and civil partners are automatically assessed on a 50/50 split by HMRC. If the actual beneficial ownership is different, for example 90/10, you must file aForm 17 declaration evidenced by a Deed of Trust to have HMRC recognise the different split.
This has significant MTD implications. A couple with £96,000 in gross rents owned 90/10 would have Partner A with £86,400 of qualifying income and Partner B with only £9,600. Partner B would have no MTD obligation under any current threshold. Form 17 changes must reflect genuine economic reality. they cannot be filed purely for tax advantage without underpinning documentation.
Non-married co-owners (siblings, friends, business partners) are assessed on their actual beneficial interest without the automatic 50/50 default.
Use gross rents before expenses. Expenses reduce profit but not your MTD threshold.
Under MTD, you must keep digital records for each property separately. Your software needs to track:
Your quarterly update reports the total income and expenses across your property portfolio for the quarter. The split by property is maintained in your records but you report an aggregate to HMRC.

No. All your UK rental properties are treated as a single property income business for MTD purposes. You submit one quarterly update covering all properties combined. total income and total expenses for the portfolio. Your software tracks each property individually but reports aggregate figures to HMRC.
Possibly, but only through a formal HMRC withdrawal process. You cannot simply stop filing quarterly updates because you expect a lower income year. You must notify HMRC that your qualifying income has dropped below the threshold and receive formal written confirmation before ceasing submissions. Continue filing until that confirmation arrives.
If you let a room in your own home on Airbnb, the first £7,500 per year is covered by the Rent a Room exemption and does not count. Amounts above £7,500 count as property income. If you let an entire property you do not live in on Airbnb, the full gross amount counts as UK property rental income. now treated the same as any other short-term let following the FHL abolition.
Overseas property rental income is currently excluded from MTD ITSA qualifying income. It does not count towards your threshold. However, it remains taxable in the UK if you are UK resident, and must still be reported through your Final Declaration. HMRC has indicated overseas property may be brought into MTD at a later stage.
