Making Tax Digital for Landlords: Thresholds, Joint Ownership, and What to File

Landlords are half the population Making Tax Digital was built for, and property income comes with rules that sole-trader guides skip entirely. Your threshold is decided by gross rent before any costs, jointly owned property is assessed per owner rather than per property, and there is a concession for joint owners that most coverage misses.

MTD for Income Tax became mandatory on 6 April 2026 for those with qualifying income over £50,000. If you let property in the UK, here is what applies to you specifically.

Key Takeaways

• Your threshold is based on gross rents, before letting agent fees, maintenance, or mortgage interest
• UK property and foreign property are separate businesses with separate quarterly updates
• Joint owners are assessed individually on their share — there is no joint registration
• Jointly owned property gets a concession: report income quarterly, but expenses only annually
• Under £90,000 you can report three-line summaries instead of a category breakdown
• Late quarterly updates carry no penalty points during 2026/27

When MTD Applies to You

HMRC works out your qualifying income from the tax return whose filing deadline fell just before the tax year starts. For Phase 1, that is your 2024/25 return filed by 31 January 2026.

The Gross Rent Trap

This is the detail that catches landlords out, and it catches them hard.

Qualifying income means total gross income from self-employment and property — turnover before any expenses. For a landlord, that is the rent as it lands, before letting agent commission, before maintenance, before insurance, and critically before mortgage interest.

A landlord collecting £55,000 in rent against £48,000 of costs has a taxable profit of £7,000 and qualifying income of £55,000. They are in Phase 1. Someone reasoning from their profit figure would conclude they had years to prepare, and would be wrong by two years.

If you also trade as a sole trader, the two are added together. £30,000 of freelance turnover plus £25,000 of gross rents is £55,000 of qualifying income, even though neither business would cross the threshold alone.

Who Is Outside MTD

• Limited companies. If your property is held in a company, MTD for Income Tax does not apply — that is MTD for Corporation Tax, which has no confirmed start date.
• Income below the threshold. Under £20,000 of qualifying income, you are not currently in scope at all, though HMRC has said it will review this.
• Digital exclusion exemptions. Age, disability, remoteness without reliable internet, or religious objection. Applications are assessed individually, and an existing MTD for VAT exemption does not carry over.

UK and Foreign Property Are Separate Businesses

If you let property both in the UK and abroad, those are two separate property businesses under MTD. Each files its own quarterly updates.

The same applies if you also trade. A landlord who does consultancy on the side has a property business and a self-employment business, and submits separate quarterly updates for each.

The practical consequence is worth planning for: check that whatever software you choose actually supports every income source you have. Foreign property is one of the areas where recognised products differ most, and discovering the gap after you have signed up is avoidable.

Joint Ownership: How It Actually Works

Most jointly let property is held by couples, and the rules here are more forgiving than people expect.

Each owner is treated as an individual taxpayer. There is no joint registration for a property. HMRC assesses each person on their own qualifying income — your share of the gross rent, not the property's total.

That means a couple jointly letting a property generating £60,000 in gross rents have £30,000 each. Neither is in Phase 1 from that property. Both would come into scope in April 2027 if they have no other qualifying income.

The Concession on Expenses

HMRC issued an update notice in January 2025 recognising that joint ownership adds real complexity, and it made a genuinely useful accommodation.

For jointly owned property:

• Income must be recorded quarterly, in line with normal MTD principles
• Expenses need only be recorded annually, as part of the end-of-year submission

So joint owners can submit only their share of gross rental income in each quarterly update, and defer their share of expenses to the Final Declaration.

That removes the worst of the coordination problem — you and your co-owner no longer have to agree on every maintenance invoice four times a year. You still need the expense records eventually, and they still need to be accurate at year end. The concession changes when you report, not whether you keep records.

If you would rather report expenses quarterly anyway to keep an accurate running picture of your position, you can.

What a Quarterly Update Involves

A quarterly update is a cumulative year-to-date summary of income and expenses. It is not a tax return, and it is not a calculation of tax owed.

Because updates are cumulative, a repair invoice you overlook in Q1 is picked up automatically when Q2's year-to-date figures go in. There is no amendment process.

After Q4, a Final Declaration by 31 January replaces your Self Assessment return, pulling in all your other income. There is no separate End of Period Statement — that step was dropped before MTD went live, so older guides describing it are out of date.

Three-Line Summaries Under £90,000

If your annual income from property or self-employment is under £90,000 — the VAT registration threshold — you can report a single total for income and a single total for expenses each quarter, with no category breakdown required.

That is most landlords. It makes the quarterly obligation genuinely light, provided your underlying records are accurate enough that the totals mean something.

Mortgage Interest and Finance Costs

Finance cost relief works the same way it does now: relief on mortgage interest for residential property is given as a basic-rate tax reducer rather than as a deductible expense, and that calculation happens at the Final Declaration stage rather than in your quarterly updates.

Quarterly updates report your income and expenses. The tax treatment — including the finance cost restriction, the property allowance, and any other reliefs — is applied when the return is finalised. If your quarterly figures look like they overstate your profit, that is usually why.

What Records You Actually Need

MTD requires digital records of property income and expenses. In practice, for a landlord, that means:

• Rent received — including any paid directly to a letting agent on your behalf
• Letting agent statements — the gross rent and the commission deducted, not just the net figure that reaches your account
• Maintenance and repair invoices — the ones most likely to arrive as a photograph of a paper invoice
• Insurance, ground rent, service charges
• Mortgage interest statements
• Professional fees — accountancy, legal, inventory

The agent statement is the one worth flagging. If your agent pays you rent net of commission, your bank shows the net figure — but your records need the gross rent as income and the commission as an expense. Recording only what hit your account understates both sides and gets your threshold calculation wrong.

Retention is unchanged: at least 5 years after the 31 January filing deadline. See our guide to HMRC record keeping requirements for the detail.

Penalties: What Applies This Year

There is a meaningful concession in the first mandated year.

Late quarterly updates carry no penalty points during 2026/27. Confirmed at Autumn Budget 2025. Points do apply to a late annual return, and they apply to quarterly updates from 2027/28 onwards.

Late payment penalties apply in full: 3% of tax outstanding at day 15, a further 3% at day 30, then 10% per year charged daily. For your first year in the new system you get an extra 15 days before the first charge.

Getting Ready

1. Work out your real qualifying income. Pull your latest Self Assessment return and find gross rents — the turnover figure, before costs. Add any self-employment turnover. That number, not your profit, decides your wave.

2. Start recording digitally now, whatever your wave. The mandate is a filing change. It only becomes painful if it arrives at the same time as a bookkeeping overhaul. Landlords in Phase 2 and 3 have a year or two, and the cheapest version of this is to be already keeping records properly when the date arrives.

3. Choose software that covers your income sources. UK property, foreign property, and any trade you run all need supporting. Use HMRC's software finder — it filters on exactly this. Our MTD software guide covers how to choose between the types.

4. Sort out the receipts problem before the deadline, not after. Rent arrives as clean bank transactions. Costs do not — they arrive as invoices from tradespeople, agent statements, and photographs of paper. That mismatch is what makes quarterly reporting harder than it looks. Keeping MTD-ready digital records covers how to close it.

Frequently Asked Questions

Does MTD apply to landlords?

Yes. MTD for Income Tax applies to sole traders and landlords with qualifying income over the threshold for their phase — £50,000 from April 2026, £30,000 from April 2027, and £20,000 from April 2028.

Is the threshold based on rent or profit?

Gross rent, before any expenses. Letting agent fees, maintenance, insurance, and mortgage interest are all ignored for the threshold test. This is the single most common misunderstanding among landlords.

How does MTD work for jointly owned property?

Each owner is assessed individually on their share of the gross rent — there is no joint registration. A concession for jointly owned property means income must be reported quarterly but expenses need only be recorded annually as part of the year-end submission.

Do I need separate quarterly updates for each property?

No — properties are grouped into property businesses, not reported individually. But UK property and foreign property are separate businesses, so those file separately, as does any self-employment.

What if I only own one rental property?

You are in scope only if your qualifying income crosses the threshold. One property generating under £20,000 in gross rent, with no other qualifying income, is currently outside MTD altogether.

Do I have to report expenses every quarter?

For solely owned property, yes — though under £90,000 you can report a single total rather than a category breakdown. For jointly owned property, expenses can be deferred to the annual submission. Our MTD quarterly update checklist covers what to reconcile before each deadline.

What happens to my Self Assessment return?

The Final Declaration replaces it for MTD income. Other income — employment, dividends, savings, capital gains — is reported through the Final Declaration too, due 31 January as now.

Will I be fined for a late quarterly update this year?

No penalty points for late quarterly updates during 2026/27. Late payment penalties still apply, and a late annual return still earns a point.
