The biggest change to how UK landlords report rental income is already here. Here’s what you actually need to do and when without the HMRC jargon.
What MTD for Income Tax actually means for landlords
MTD ITSA isn’t just a rebrand of Self Assessment. It’s a fundamental change to the rhythm of how you report income to HMRC. Instead of one annual tax return filed in January, you’ll now submit four quarterly updates throughout the year, plus a final end-of-period statement and a declaration to wrap things up.
Think of it like switching from one big annual report to a running commentary. HMRC wants to see your income and expenses as the year unfolds, not months after the fact. The annual scramble through bank statements and receipts in January is supposed to become a thing of the past.
Honestly, the concept isn’t unreasonable. Keeping records throughout the year and submitting them digitally is just good financial hygiene. The problem is the transition and the fact that HMRC hasn’t exactly made it straightforward to understand what’s required.
Key distinction
MTD ITSA applies to Income Tax, not Corporation Tax. If you hold your properties through a limited company, this doesn’t apply to you yet. It’s specifically aimed at individual landlords and sole traders filing personal tax returns.
Who’s in scope and who isn’t yet
The rollout is phased. And this is where a lot of confusion lives, because the goalposts moved more than once in the lead-up to 2026.
April 2026 — Now live
Landlords & sole traders with gross income over £50,000
If your total gross income from rental properties plus any self-employment income exceeds £50,000 in the 2024/25 tax year, MTD ITSA applies to you from April 2026.
April 2027 — Coming soon
Those earning between £30,000 and £50,000
The second wave brings in landlords and sole traders with gross income between £30,000 and £50,000. If you’re in this bracket, now is the time to prepare, not April 2027.
TBC — Under consultation
Under £30,000 — date not yet confirmed
HMRC has signalled an eventual extension to lower income thresholds, but no confirmed date. Watch this space, it will come.
Here’s what most people miss: the £50,000 threshold is your gross income, not your profit. Rental income before mortgage interest, maintenance costs, and agent fees counts toward that figure. If your total rent received across all properties exceeds £50,000, even if your actual profit is a fraction of that, you’re in scope from 2026.
Do you know what your gross rental income was in the 2024/25 tax year? Not your profit, your gross income. That number determines whether you need to act already.
Quarterly updates explained without the spin
Four times a year, you’ll submit a summary of your rental income and allowable expenses to HMRC through MTD-compatible software. These aren’t tax returns, they’re updates. You don’t pay tax four times. Tax is still calculated and paid based on your end-of-year position.
The quarterly deadlines work like this. Your tax year runs from April to April, and each quarter closes at the end of July, October, January, and April. You get one month after each quarter closes to submit your update. Miss it, and the new penalty points system kicks in, accumulate enough points, and financial penalties follow.
Quarterly updates are a reporting rhythm, not four tax bills. The payment structure doesn’t change your record-keeping habit, do.
What goes in a quarterly update? It’s simpler than it sounds. Gross rental income received during the quarter and Allowable expenses for the same period. That’s it. No complex calculations, no tax liability assessment, just clean income and expense data submitted digitally. The complexity lies in getting your records clean enough to do that without scrambling.
Real situation
A landlord client of ours, semi-retired with three properties in Essex, a total rental income of around £58,000 gross, came to us in late 2025, absolutely convinced he wasn’t in scope. He’d read somewhere that the threshold was £50,000 profit, not gross income.
He’d been recording everything in a spreadsheet since 2019. No cloud software, no digital receipts, just a shared Excel file which his daughter helped him set up. When we explained the actual rules and the April 2026 start date, he had about five months to switch his entire record-keeping process to compatible software and backfill his 2024/25 records digitally.
We got it done. But it was a stressful five months that didn’t need to be stressful at all. The lesson: if you have a spreadsheet habit and rental income above £50k gross, the clock started ticking for you some time ago.
Software: What qualifies, what doesn’t qualify
This is non-negotiable under MTD. You cannot submit quarterly updates manually, through HMRC’s own website, or via a spreadsheet without a verified digital bridge. The entire point of MTD is a continuous digital record, and HMRC’s systems will only accept submissions from approved software.
For landlords, the main options break into three categories:
Recommended options for landlords
Property-specific: Hammock, Arthur, and Landlord Studio are built specifically for rental income tracking. They understand property portfolios, handle multiple tenancies, and generate MTD-compliant submissions.
General accounting platforms: Xero, QuickBooks, and Sage are all MTD-compatible and work well if you also have self-employment income alongside rental.
Bridging software: If you absolutely must keep your spreadsheet, tools like BTC Software or Absolute Tax create a compliant digital link, but this is the most fragile setup and not recommended long-term.
What doesn’t qualify
A regular Excel or Google Sheets spreadsheet on its own. Manual entry directly into HMRC’s website. Any system where you type numbers from one source into another by hand that breaks the digital link and puts you out of compliance, even if the numbers are correct.
The complete 2026 compliance checklist
Tick these off as you go. The interactive version below tracks your progress, but if you’re printing this, you know what to do.
1) Establish your position. Do this first
0 of 4 complete
- Calculate your gross rental income for 2024/25
- Total rent received before any deductions. This determines whether you’re in scope from April 2026.
- (Urgent)
- Confirm whether you also have self-employment income
- Rental income and self-employment income are combined for threshold purposes. Both count toward the £50,000 limit.
- (Urgent)
- Check if your properties are held personally or via a company
- Company-held properties are not in scope for MTD ITSA. Only personally held rental income counts.
- (Important)
- Confirm your April 2026 or April 2027 start date
- Above £50k gross: in scope now. £30k–£50k: in scope from April 2027. Below £30k: no confirmed date yet.
- (Important)
2) Set up your digital records before your start date
0 of 4 complete
- Choose and set up MTD-compatible software
- Hammock, Landlord Studio, Xero, or QuickBooks. Check HMRC’s approved software list and set up your account before your first quarter starts.
- (Required)
- Migrate existing records into the new system
- Your 2025/26 income and expenses need to be digitally recorded from April 2025. Backfilling manually is tedious but necessary.
- (Required)
- Set up a separate business bank account (if not already done)
- Not legally required, but mixing personal and rental finances makes digital record-keeping significantly harder. Separate accounts make your software feed clean.
- (Strongly advised)
- Connect your bank feed to your accounting software
- Automated bank feeds eliminate manual entry and maintain the unbroken digital chain HMRC requires. Most platforms support this natively.
- (Best practice)
3) Quarterly submission rhythm, Ongoing from start date
0 of 4 complete
- Diary the four quarterly deadlines
- Quarters close in July, October, January, and April. Submissions are due one month after each close. Set calendar reminders now; they’re easy to forget in day-to-day life.
- (Required)
- Categorise allowable expenses correctly from the start
- Mortgage interest (as a 20% tax credit, not a deduction), repairs, letting agent fees, insurance, and professional fees are all allowable. Capital improvements are not.
- (Important)
- Submit your end-of-period statement after Q4
- The EOPS finalises your property income position for the year, capturing any adjustments, reliefs, or allowances not included in quarterly updates.
- (Required)
- File your final declaration and pay your tax by 31 January
- The final declaration replaces the old Self Assessment return. Tax payment deadlines remain unchanged, 31 January for the balance and any payment on account.
- (Required)
Expense tip from SKZ Accountants
The mortgage interest restriction catches a lot of landlords off guard. You can no longer deduct mortgage interest directly from rental profit; instead, you get a 20% tax credit against your tax bill. Higher-rate taxpayers are disproportionately affected. If you haven’t modelled this yet, do it before your next return.
The honest verdict
Here’s where I’ll stop being diplomatic. MTD ITSA is not going away. HMRC delayed it twice, refined the thresholds, consulted extensively, and it’s still here, live, affecting landlords right now. The idea that it might get scrapped or postponed again is a comfortable fiction that’s going to cost some people real money.
The landlords who will struggle most aren’t the ones with complex portfolios. They’re the ones with two or three properties, modest rental income, and a firmly held belief that it’ll all be fine because it’s always been fine. That belief was reasonable until about 2024. It isn’t now.
The bottom line
If your gross rental income is above £50,000 and you haven’t already set up MTD-compatible software and started submitting quarterly updates, you are already non-compliant. Not “at risk of becoming non-compliant.” Already there.
The penalty points system means the first miss feels like a small one point, with no immediate financial penalty. But points accumulate, and four points mean a £200 fine. Beyond that, daily penalties kick in. The numbers aren’t catastrophic individually, but they compound quickly, and HMRC’s tolerance for “I didn’t know” has narrowed considerably since DAC7 data-sharing came in.
Get the software sorted. Get your records clean. Talk to an accountant who actually understands MTD, not one who’s googled it once. The quarterly rhythm, once it’s set up properly, genuinely is less painful than a January panic. But the setup has to happen first, and that window is smaller every month you wait.
