Making Tax Digital for landlords: the complete 2026 guide

Quick answer: Making Tax Digital for Income Tax (MTD for ITSA) is a new way of reporting rental profit to HMRC: you keep digital records, send four quarterly updates a year, and file a final declaration instead of a Self Assessment return. It applies to landlords whose gross rents (plus any self-employment turnover) go over £50,000, £30,000 or £20,000 — phased in from April 2026, 2027 and 2028.

If you rent out property in the UK, Making Tax Digital is the biggest change to how you report to HMRC in a generation. The good news: the tax you owe does not change. What changes is how often and how you report it. This pillar guide walks through the whole picture — who's affected, when, and what the new routine looks like — and links out to deeper guides on the parts landlords ask about most.

What Making Tax Digital for landlords actually is

Today, most landlords file one Self Assessment tax return a year, with the SA105 property pages, by 31 January. Under Making Tax Digital for Income Tax that single annual return is replaced by a digital, quarterly rhythm:

• You keep your rental records digitally in compatible software (no more shoebox of receipts totted up in a spreadsheet at year end).
• You send HMRC four quarterly updates — running totals of your income and expenses to date.
• After the tax year ends you submit a final declaration that confirms the year's figures and brings in anything else (other income, reliefs, adjustments). This replaces the old SA return.

So it's five submissions a year instead of one. The upside is that your numbers stay current all year, and there are no year-end surprises. For the official overview, see GOV.UK's Making Tax Digital for Income Tax collection and its step-by-step guide for landlords.

Who's in scope — and it's your gross rents that count

This is the single most misunderstood point, so let's be precise. Whether you're mandated depends on your qualifying income — and for landlords that means gross rents, before any expenses. Not your profit. Not the amount left after the mortgage. The rent your tenants pay you.

Your qualifying income is your gross self-employment turnover plus gross property income added together. It excludes PAYE salary, dividends, savings interest and pensions. HMRC measures it from your prior-year Self Assessment return. GOV.UK explains this in Work out your qualifying income for Making Tax Digital for Income Tax.

The thresholds and dates (2026):

Note the thresholds are strict: "over" the figure, not "at" it. Rents of exactly £30,000 don't cross the £30,000 line. For the official eligibility rules, see Find out if and when you need to use Making Tax Digital for Income Tax.

Worked example. Priya lets two flats. One brings in £1,400 a month, the other £1,150 a month. That's £30,600 a year in gross rent. Her mortgage interest and agent fees are hefty, so her profit is only about £9,000 — but Making Tax Digital doesn't look at profit. £30,600 is over £30,000, so if that figure appears on her 2025/26 return she'll be mandated from 6 April 2027. She should get her records digital during 2026. You can sanity-check your own position with the MTD Scope Checker and see exactly when with the MTD Deadline Calculator.

All your UK rentals are one "property business"

Landlords often assume they'll report each property to HMRC separately. You won't. For MTD purposes, all your UK rental properties together are a single UK property business and you send HMRC one set of quarterly figures covering the lot. You do not file per-property to HMRC.

Two things worth knowing:

• Foreign property is separate. Overseas lettings are a different source with their own reporting, kept apart from your UK property business.
• Per-property records are still useful — for your own management, and because good software can give you a per-property profit view even though HMRC only sees the combined total. (Ledgers, for example, tracks each property internally while reporting one UK property business to HMRC.)

The new routine: four quarterly updates plus a final declaration

Once you're mandated, the calendar looks like this every year. Quarterly updates are cumulative — each one is the year-to-date total, not just that quarter:

The final declaration is where you confirm the full-year figures, claim reliefs and allowances, and declare any other income. It replaces your Self Assessment return. Our sibling guide How to submit an MTD quarterly update to HMRC walks through a single update end to end.

Soft-landing year. For the first £50k cohort only, 2026/27 is a soft-landing year: HMRC won't apply late-submission penalty points to the quarterly updates. Late-payment penalties and interest, and the final declaration deadline, still apply. If you want to understand how the points system bites once soft-landing ends, use the MTD Penalty Calculator and read What happens if I miss an MTD quarterly update?.

The jointly-owned property easement

Plenty of landlords own property with a spouse, partner or sibling. HMRC operates a helpful easement for jointly-owned property under MTD. Joint owners can:

• keep less-detailed digital records for the jointly-owned property, and
• bring in the expenses annually rather than quarter by quarter.

That materially cuts the admin for couples. There's real nuance here — how income is split, the 50/50 default for spouses and civil partners, and Form 17 for unequal shares — so we've given it its own guide: Making Tax Digital for jointly-owned property.

Section 24 mortgage interest, in brief

If you let residential property with a mortgage, Section 24 matters. Since 2020/21, residential finance costs (mortgage and loan interest, and some related fees) are not deducted from your rental profit. Instead you get a basic-rate (20%) tax reducer on those finance costs, applied to your tax bill. On the SA105 there's a specific box for residential finance costs.

The practical effect: your reported profit looks higher than your cash reality, and higher-rate taxpayers feel the pinch most. GOV.UK sets out the mechanics in Tax relief for residential landlords: how it's worked out. We break it down with numbers in Section 24: mortgage interest relief for landlords.

Cash basis is the default

Since 2017/18, the cash basis has been the default for most property businesses — you record income when it lands and expenses when you pay them, no accruals or debtors/creditors. You can elect the accruals basis instead if it suits you, but for most individual landlords the cash basis is simpler and now standard. See HMRC's Property Income Manual on the cash basis (PIM1090).

A couple of related points landlords ask about:

• £1,000 property allowance. If your gross property income is £1,000 or less, it's tax-free and you needn't report it. Above that, you can choose to deduct the £1,000 allowance instead of actual expenses — see Tax-free allowances on property and trading income.
• FHL abolished. The Furnished Holiday Lettings regime was abolished from 6 April 2025 — there are no more FHL-specific reliefs.
• No Class 2 / Class 4 NIC. Rental income isn't a trade, so National Insurance doesn't apply to rental profit.

What to do now

You don't need to panic, but you do need to prepare. A sensible order:

1. Find your number. Add up your gross rents (plus any self-employment turnover). That's your qualifying income — use the MTD Scope Checker.
2. Find your date. Match your number to the 2026/2027/2028 waves with the MTD Deadline Calculator. Remember the £30k cohort is identified from the 2025/26 return filed by 31 January 2027, so £30k landlords should get ready during 2026.
3. Go digital early. Move off spreadsheets and paper into compatible software before you're mandated, so quarter one isn't a scramble.
4. Sort joint ownership. If you co-own, read up on the easement and check whether Form 17 applies.
5. Understand Section 24. Know how finance costs hit your bill so the final declaration holds no surprises.

Frequently asked questions

Do I have to sign up for Making Tax Digital if I'm a landlord?

Only if your qualifying income is over the relevant threshold. That's your gross rents (plus any self-employment turnover), before expenses, measured on your prior-year Self Assessment return: over £50,000 mandates you from April 2026, over £30,000 from April 2027, and over £20,000 from April 2028. Below £20,000 you're not currently mandated, though HMRC may extend it later.

Is it my rental profit or my gross rent that counts?

Your gross rent — the full amount before you deduct the mortgage, agent fees or repairs. This trips up a lot of landlords whose profit is small but whose turnover is well over the threshold. See Work out your qualifying income.

Do I report each property separately to HMRC?

No. All your UK rental properties count as a single UK property business, and you send HMRC one combined set of quarterly figures. Foreign property is a separate source. Good software can still show you per-property profit for your own use.

How many times a year will I report under MTD?

Five times: four cumulative quarterly updates (due 7 August, 7 November, 7 February and 7 May) plus a final declaration by 31 January, which replaces your Self Assessment return.

I own a rental jointly with my spouse — is it simpler?

Usually, yes. HMRC's easement lets joint owners keep less-detailed digital records and bring in expenses annually rather than every quarter. Spouses and civil partners are taxed 50/50 by default unless a Form 17 election reflects actual unequal shares. Full detail is in our jointly-owned property guide.
