MTD applies to rental income as well as sole-trade income, and there are a few landlord-specific wrinkles worth knowing. This guide covers them.
What income counts
For MTD purposes, your property income is your gross rent before expenses, not your profit after expenses. Rent, plus any other receipts you treat as property income (ground rent you receive, for example), plus service charges you charge on top of rent.
The qualifying-income test for MTD lumps together:
- UK residential and non-residential property, and
- Foreign property (if you declare it in UK Self Assessment).
All of this is added to any sole-trade income you have to decide whether you're over the threshold.
Furnished holiday lets
The old Furnished Holiday Letting (FHL) regime ended on 6 April 2025. FHL income is now just property income for all purposes, including MTD. If you previously enjoyed the FHL rules (different loss rules, pension-contribution benefits, full mortgage-interest deduction), those have gone, your accountant will have flagged this in your 2024-25 return.
How many "businesses" is this?
For MTD, HMRC groups your property income into one or two property businesses, depending on the type:
- UK property business, all your UK residential and non-residential rentals count as one business.
- Foreign property business, rentals outside the UK count as a separate business.
So one set of quarterly updates covers all of your UK rentals (whether you have one flat or fifteen). And, if applicable, a separate set covers your foreign rentals.
This is good news: a landlord with several UK properties doesn't submit a separate update for each property.
Jointly-owned property
If you own a property jointly with someone else (most commonly a spouse or civil partner):
- Qualifying-income test uses your share. When checking whether you're above the MTD threshold, use your proportion of the gross rent, not the whole property's rent. So a £40,000-rent flat owned 50/50 gives you £20,000 of qualifying income from that property, not £40,000.
- Each co-owner reports their own share. MTD is per individual; your spouse/partner has their own MTD position separate from yours.
- There's a quarterly-expenses simplification. HMRC allows landlords with jointly-owned property to choose not to submit quarterly updates of expenses for those properties. You still have to report income quarterly, but you can defer the expenses side until year-end.
That last point is a genuine admin-burden reducer if you have mixed ownership. You still need to track expenses digitally (and account for them at year-end), but you don't have to reconcile them quarter by quarter.
Expense categories you'll actually use
Unlike sole traders under £90k, landlords must always categorise their expenses. The standard categories for UK residential property:
- Premises running costs, insurance, ground rent, service charges you pay, utilities you pay.
- Repairs and maintenance, fixing things that have broken. Bigger improvements are usually capital, not revenue, and go elsewhere.
- Financial costs, loan interest and finance costs. Residential finance costs get special treatment (see below).
- Professional fees, letting agent commission, legal, accounting, tenant-referencing.
- Cost of services, gardening, cleaning, security.
- Travel, mileage or fares related to the property business.
- Other, anything genuinely business-related that doesn't fit above.
Good software prompts you to pick one of these when you categorise a transaction.
Residential finance costs (the Section 24 thing)
Allowances you might use
- Property allowance (£1,000). If your gross rents are under £1,000 you don't need to report them at all. If they're above £1,000 you can either claim the £1,000 allowance instead of actual expenses, or claim your actual expenses, whichever's better.
- Rent-a-room relief (£7,500). Applies when you let out part of your main home. If you're within rent-a-room and below the threshold, you may not need to do full MTD reporting on that income, but the rules are technical; check with your accountant or GOV.UK.
Capital vs revenue: the classic landlord trap
MTD doesn't change the rules, but it does make errors more visible:
- Revenue expenses (repairs, replacement of broken items in like-for-like terms) go through your quarterly and final figures and reduce your taxable profit.
- Capital expenditure (improvements, new kitchens in a previously kitchen-less space, a whole new boiler when the old one wasn't broken, structural work) doesn't reduce this year's income. It goes against the capital gains position when you eventually sell the property.
If you're unsure which bucket something falls into, ask your accountant before categorising. Putting a £6,000 kitchen in the wrong box is a common, avoidable mistake.
Multiple properties in one business
Your software treats your UK portfolio as one property business, so your quarterly update just shows combined totals. But you're still free to track per-property figures inside the software for your own records, most software lets you tag each transaction to a property, then roll them up for the HMRC submission.
This is worth doing. At year-end, per-property analytics help with:
- Spotting loss-making properties.
- Tracking mortgage interest per property.
- Deciding whether to sell, raise rents, or refinance.
A quick numbers example
Imagine a couple, Priya and James, jointly owning two UK rental flats:
- Flat A: £18,000 gross rent/year
- Flat B: £14,000 gross rent/year
- Total portfolio gross rent: £32,000
Each of Priya and James has £16,000 of property qualifying income.
- 2026 test (£50,000 threshold): under threshold. Neither is in MTD.
- 2027 test (£30,000 threshold): both under. Still out.
- 2028 test (£20,000 threshold): both under (£16k each). Still out, unless one also has sole-trade income that pushes them over.
If Priya later sets up a consultancy earning £10,000/year, her qualifying income becomes £16k + £10k = £26k. Over the £20k threshold, so she'd be in MTD from April 2028. James, with no sole-trade income, stays out.
This example is exactly why MTD's per-individual structure and the "your share of the property" rule matter.
Your software checklist as a landlord
- Can it handle multiple rental properties in one property business?
- Can it track per-property totals inside that business?
- Does it have a separate bucket for residential finance costs?
- Can it handle foreign property as a separate business, if you have any?
- Does it support the jointly-owned property quarterly expenses simplification (income only at quarters, expenses at year-end)?
Kite handles all of the above.
