MTD ITSA for UK Landlords: April 2026, 2027 and 2028 Explained

By RentVault Team · Published 2026-04-30 · Updated 2026-05-07 · 13 min read

MTD ITSA is now mandatory for landlords earning over £50,000 (from April 2026). The threshold drops to £30,000 in April 2027 and £20,000 in April 2028. Quarterly submissions, digital records, and what you need to do.

If you let property in the UK, your tax life has already started changing — or is about to. Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is now being rolled out by HMRC in three waves, each capturing a different income band:

• From 6 April 2026 (now in force): mandatory for landlords with combined gross rental + self-employment income over £50,000.
• From 6 April 2027: drops to £30,000.
• From 6 April 2028: drops to £20,000 — at this point essentially every landlord with even a single typically-rented UK property is in scope.

The way you keep records, submit information to HMRC, and complete your tax return is entirely different from the annual self-assessment process most landlords have used for the last twenty years. This guide explains what MTD ITSA requires, which wave applies to you, how the quarterly system actually works, and exactly what to do — whether you're already in MTD now or preparing for April 2027 or 2028.

What MTD ITSA actually requires

MTD ITSA is HMRC's modernisation of how individuals with property and self-employment income report to them. Under the new system:

1. Digital record-keeping is mandatory. Paper records, spreadsheets used informally, or shoebox-based filing are no longer compliant. You must maintain digital records of all rental income and expenses using HMRC-approved software.

2. Quarterly updates replace the annual return. Instead of one self-assessment submission per year, you submit a digital update every three months covering the previous quarter's transactions.

3. End-of-period statements replace your final return. At the end of each tax year, you submit a final adjustment statement that brings together your quarterly figures and finalises your tax position.

4. The tax calculation itself doesn't change. What you owe and when you owe it remains based on the same rules. What changes is the timing and frequency of how that information reaches HMRC.

Already in MTD: the April 2026 £50,000+ cohort

If your combined gross rental and self-employment income for the 2024/25 tax year was over £50,000, you have been mandatory in MTD ITSA since 6 April 2026. HMRC will have written to you — and your accountant, if you have one — to confirm enrolment.

Your obligations right now:

• Digital records from 6 April 2026 onwards. Every transaction (rent received, expenses paid) needs to be recorded in MTD-compliant software. Paper receipts and informal spreadsheets no longer satisfy HMRC's record-keeping rules.
• First quarterly submission due 7 August 2026. This covers the period 6 April – 5 July 2026 (Quarter 1). If you haven't yet chosen software, set up bank feeds, and categorised your April–June transactions, this is now urgent — the deadline is in three months.
• Three further quarterly submissions due 7 November 2026, 7 February 2027, and 7 May 2027.
• End-of-Period Statement and Final Declaration by 31 January 2028 to finalise your 2026/27 tax year.

The early experience of the £50,000+ cohort tells us a few things worth knowing:

• HMRC's penalty regime is currently operating on the points-based escalation rather than immediate fines, but a missed Q1 deadline still puts a point on your record.
• Landlords who set up bank feeds before their first quarterly deadline have had a much easier time than those still entering transactions manually.
• Accountants are generally up to speed, but turnaround times for setting up new MTD-agent relationships can be several weeks — don't leave this to the last fortnight before a deadline.
• The most common cause of incorrect Q1 submissions has been mis-categorised mortgage interest (should be flagged separately for Section 24 treatment, not lumped in with general expenses).

If you're in this cohort and haven't yet started, you're not alone — but every week of delay makes the August deadline harder. Set up software, connect your bank, and back-categorise April–June transactions as a single focused weekend's work.

Who is affected by the April 2027 change

The April 2027 threshold drop from £50,000 to £30,000 captures the majority of single-property landlords. To put concrete numbers on it:

• A property let at £625/month or higher generates £7,500/year minimum rent. Across many UK rental areas, average single-property gross rent comfortably exceeds £30,000
• A landlord with a moderately rented London or South East property is almost certainly above the threshold
• Most regional UK landlords with two or more properties are above the threshold
• HMOs at any reasonable scale are above the threshold

If your gross rental income (rent received, before expenses) exceeded £30,000 in the 2025/26 tax year, you must be using MTD ITSA-compliant software from 6 April 2027.

If you're below the threshold but expect to cross it, you can opt in voluntarily before becoming mandatory. Many landlords choose to do this to spread the learning curve rather than face a hard cutover.

How quarterly updates actually work

Under MTD ITSA, your tax year is divided into four quarters:

• Quarter 1: 6 April to 5 July (submission due 7 August)
• Quarter 2: 6 July to 5 October (submission due 7 November)
• Quarter 3: 6 October to 5 January (submission due 7 February)
• Quarter 4: 6 January to 5 April (submission due 7 May)

For each quarter, you submit a summary of:

• Total rental income received
• Total deductible expenses by category
• Property-by-property breakdown (if you have multiple properties)
• Any specific adjustments required

The data is submitted directly to HMRC through your MTD-compliant software. There's no PDF to download, no form to fill in by hand. The software talks to HMRC's systems via an API.

Importantly, the quarterly update is not a tax payment. It's a reporting submission. Your actual tax payment timing remains based on the existing payment-on-account system: 31 January and 31 July each year.

End-of-period statement and final declaration

After your fourth quarter submission, you have until 31 January following the end of the tax year (the same deadline as the current self-assessment) to submit two further statements:

End-of-Period Statement (EOPS): This adjusts your quarterly figures for the full year, captures any items that wouldn't have been in the regular quarterly flow (such as capital allowances, balancing charges, or other tax adjustments), and finalises your business income figures.

Final Declaration: This is your full self-assessment for the year, including any other income (employment, dividends, savings, capital gains). Effectively this replaces what was the self-assessment return.

The 31 January deadline is the same hard deadline you've worked to under self-assessment. The difference is that by the time you reach it, you've already submitted four quarterly updates throughout the year, so the final reconciliation is much smaller in scope.

What this means in practice

For landlords used to gathering paperwork once a year and submitting one self-assessment return, MTD ITSA represents a significant change in working pattern.

You can't ignore your books for 11 months and panic in January. Quarterly updates require quarterly bookkeeping. You either need to maintain digital records as transactions happen, or do quarterly catch-up sessions.

Bank reconciliation becomes more important. With quarterly submissions to HMRC, errors compound — getting a quarter wrong means correcting it at year-end. Most software addresses this through automated bank feeds that import transactions and let you categorise them as you go.

You need MTD-compliant software from day one. HMRC's free tools are limited and don't well-handle property-specific scenarios (Section 24 mortgage interest treatment, Rent-a-Room scheme, jointly-owned property). Most landlords will need third-party software.

Mistakes are costlier. Under self-assessment, an error caught before submission is fine. Under MTD ITSA, errors in quarterly submissions create amendments later — which works fine but creates more administrative load.

Joint properties need careful handling. If you and your spouse jointly own a rental property, both of you need to handle MTD requirements for your share. Most software supports this through profile sharing or paired accounts.

Furnished holiday lettings are now under MTD too. FHLs and Airbnb-style lets aren't exempt. They follow the same MTD framework but with FHL-specific tax treatment.

What you need to do before April 2027

The list of preparation items, in priority order:

1. Confirm whether you're in scope

Calculate your 2025/26 gross rental income (rent received, before expenses). If above £30,000, you're mandatory from April 2027. If below, check whether your 2026/27 projection is likely to push you above. If it is, treat yourself as mandatory.

If you have self-employment income alongside property income, the threshold applies to combined income from both sources.

2. Choose MTD-compliant software

The software must be on HMRC's approved list. Options include:

• General accounting software (Sage, Xero, QuickBooks, FreeAgent) — works but isn't landlord-specific
• Landlord-specific platforms (Hammock, RentVault, others) — built for property income
• Personal finance software with MTD modules

For property-only income with no self-employment, landlord-specific software typically handles the property-specific scenarios (Section 24, Rent-a-Room, jointly-owned property, capital gains on disposal) better than general accounting software designed for sole traders. The cost difference is usually small and the tax-handling benefit is significant.

3. Set up your bank feeds

Most MTD platforms integrate with UK banks via Open Banking (the same secure connection used by Plaid, TrueLayer, and others). Setting up bank feeds means your rental income and expenses appear in your software automatically — you just categorise them.

Without bank feeds, you're manually entering every transaction, which most landlords give up on after a quarter.

4. Categorise your historical year

Before April 2027, work through your 2026/27 transactions and categorise them. This:

• Establishes your software's baseline
• Catches any uncategorised transactions
• Lets you spot patterns and improvements
• Creates the muscle memory for ongoing categorisation

If you do this in March 2027, you're ready to submit your first quarterly update by August 2027.

5. Understand Section 24 in your software

Section 24 — the mortgage interest restriction that hit landlords from 2017 — is technically complex. Mortgage interest is no longer fully deductible from rental income; instead, you receive a 20% tax credit on the interest figure.

Most MTD software handles this automatically, but you need to confirm:

• Your software correctly identifies mortgage interest separately from other expenses
• The Section 24 calculation in your year-end statements is correct
• Property-by-property breakdowns work for the calculation

If you have mortgages on your rental properties (most landlords do), this is critical to get right.

6. Address jointly-owned properties

If you and your spouse own properties jointly, you each need MTD-compliant systems for your share of income and expenses. Most platforms support this through linked accounts or shared profiles.

7. Plan for capital gains

While MTD ITSA itself focuses on income tax, your capital gains position matters at the point of sale. Some MTD platforms track unrealised capital gains so you have proper visibility ahead of any sale or refinancing decision. Others don't.

If you're approaching a capital gains event (selling a property, transferring ownership, transferring into a SPV), have your software set up to track this properly.

Common questions about MTD ITSA

Q: What if I miss a quarterly deadline?

HMRC's penalty regime for late MTD submissions includes points-based escalation. A first missed deadline results in a point. Accumulating points triggers actual financial penalties. The early experience suggests HMRC is using the point system rather than immediate fines, but this won't stay lenient indefinitely.

Q: Can I still use my accountant?

Yes. Accountants can submit on your behalf if they have agent authorisation through HMRC and the appropriate software. Many accountants have updated their workflows for MTD ITSA. Some haven't yet — worth checking with yours specifically about their MTD capability.

If you currently use an accountant for an annual self-assessment, you may find their fees increase under MTD ITSA because they're doing more frequent work for you. Some landlords find it more cost-effective to use software directly and have an accountant review at year-end only.

Q: Do I need different software for different income types?

If you have property income only, one MTD-compliant platform handles everything. If you have property income plus self-employment (e.g. you're also a freelance consultant), most platforms can handle both, but you need to confirm this when choosing.

If your business structure is complex (Ltd company landlord plus personal property plus consultancy income), you may need multiple platforms or accountancy software that handles multiple income streams.

Q: What about Rent-a-Room?

The Rent-a-Room scheme (£7,500 per year tax-free for letting a furnished room in your main residence) is unaffected by MTD ITSA in principle. However, if your overall rental and self-employment income exceeds the threshold, you still need to be in MTD ITSA — the Rent-a-Room income just gets specific treatment within it.

If your only rental income is under the Rent-a-Room threshold and you have no other self-employment, you may not need MTD ITSA at all because you're not declaring rental income to HMRC.

Q: I have one property and earn under £30,000 in rent. Am I affected?

Not from April 2026 (£50,000+ threshold) or April 2027 (£30,000+ threshold) directly. But the threshold drops to £20,000 from April 2028, which captures essentially every landlord with even a single property. Plan to be MTD-ready by April 2028 at the latest.

Voluntary early adoption is straightforward and means you face the change in your own time rather than under deadline pressure.

Q: I'm already in MTD as of April 2026 — what should I prioritise this month?

Three things, in order: (1) confirm software set up and HMRC-connected; (2) connect your bank feeds so April–July transactions import automatically; (3) back-categorise the transactions you already have so your first Quarter 1 submission on 7 August 2026 is built on clean data. If you haven't done step 1 yet, that's the urgent priority — software approval and HMRC connection can take a couple of weeks if anything goes sideways.

Q: What about overseas property income?

UK residents are taxed on worldwide income, so overseas rental income is reportable to HMRC — but it is not included in your MTD ITSA quarterly returns. Overseas property income is reported on the Foreign Income pages of Self Assessment, separately from your UK MTD obligations. Foreign Tax Credit Relief may apply if you've already paid tax on the income in the country where the property sits.

In practice this means: if you have a Spanish villa let on Airbnb and a UK buy-to-let, your MTD quarterly submissions cover the UK property only. The Spanish income goes on the Foreign Income pages of your annual Final Declaration. Currency conversion uses HMRC's published exchange rates for the relevant period.

This is technical territory and country-specific obligations vary — please get advice from an accountant familiar with cross-border property tax. Inside RentVault, classifying a property as "Overseas" rather than "UK rental" keeps it out of your MTD export and into a separate portfolio category.

Q: What about properties held in a limited company or SPV?

Income from properties held by a UK limited company (including SPVs) is taxed within that company under Corporation Tax — it does not appear on your personal Self Assessment or your MTD ITSA submission at all. Your personal MTD threshold (£50k / £30k / £20k by year) is calculated only on income that flows into your personal name.

If you hold rental property in a mix of personal name and Ltd company, you need to keep the two streams completely separate for tax purposes: the personal portfolio feeds your MTD ITSA quarterly returns; the company portfolio feeds the company's annual Corporation Tax return. RentVault tracks both for management and compliance purposes, but the company-held properties are excluded from the MTD ITSA export.

Q: How does joint ownership work for the MTD threshold?

Only your share of jointly-owned property income counts towards your personal threshold and goes on your MTD return. If you and your spouse jointly own a property generating £40,000 of gross rent and your share is 50%, your personal share is £20,000 — your spouse reports their £20,000 share on their own return. The same logic applies to expenses: each owner reports their share.

This matters for threshold calculations. A couple jointly owning a £55,000-rent property each report £27,500 — both below the £30,000 (April 2027) threshold individually. But cross income from any other rental or self-employment in your own name combines with this to determine your overall threshold position.

Q: Do property losses still work the same way?

Yes. Property losses can be carried forward to offset future property income, in line with existing rules. The MTD framework just changes how you report the figures, not what they mean for tax.

The bigger picture: why MTD matters strategically

MTD ITSA is not just an administrative change. It's HMRC's mechanism for moving towards real-time visibility of taxpayer data. Once digital records flow continuously to HMRC:

• HMRC's enforcement capability significantly increases — they see issues much faster
• The previously-common "I'll deal with it at year-end" approach becomes harder
• Audit risk for landlords with poor records goes up substantially
• Compliant landlords with accurate digital records have less HMRC interaction, not more

The landlords who do well under MTD are those who run their businesses in a properly documented way. The landlords who struggle are those whose record-keeping was always informal.

For most professional landlords, MTD ITSA is actually a positive change. Better systems lead to better tax outcomes, fewer mistakes, and less stress at year-end. The transition is real work, but the steady-state is generally easier than the old self-assessment grind.

How RentVault helps with MTD ITSA

RentVault is built specifically for UK landlords navigating MTD ITSA. Our platform includes:

• HMRC-compliant quarterly submissions across all four quarters
• Automatic bank feed reconciliation via Open Banking (powered by TrueLayer)
• Section 24 calculations that automatically apply to mortgage interest
• Jointly-owned property handling for spouse-shared portfolios
• Property-by-property breakdowns required for accurate tax submission
• Year-end statements and final declarations
• Capital gains tracking for properties in your portfolio
• Rent-a-Room scheme handling within the broader framework
• Overseas property tracking (recorded separately from your MTD scope, since overseas rental income is reported on the Foreign Income pages of Self Assessment rather than in MTD ITSA quarterly returns)
• Limited company / SPV property tracking (kept separate from your personal MTD scope, since company-held property income is taxed under Corporation Tax)

If you're already in the April 2026 cohort, your first Quarter 1 deadline (7 August 2026) is now imminent — software, bank feeds, and back-categorisation can be done in a focused weekend, but the time to do that weekend is now, not late July. If you're in the April 2027 (£30,000+) or April 2028 (£20,000+) wave, you have more breathing room — but landlords who set up 12 months ahead of their deadline consistently report a smoother experience than those who leave it until the final quarter.

The landlords who move first benefit. The landlords who wait struggle. Whichever wave applies to you, the right time to start is the same: now.
