Making Tax Digital for Income Tax is now live, and landlords with qualifying rental income over £50,000 must submit quarterly digital updates to HMRC instead of a single annual tax return. The first mandatory quarter began on 6 April 2026, with the opening deadline of 7 August 2026 already behind many landlords, making this checklist essential for anyone still getting up to speed.
Who Must Comply and When
From 6 April 2026, sole trader landlords whose combined gross income from rental properties and self employment exceeded £50,000 in the 2024 to 2025 tax year are mandated into MTD. The threshold drops to £30,000 from April 2027, then to £20,000 from April 2028, pulling progressively more landlords into the regime. Limited companies are not currently in scope, since MTD for Income Tax applies only to unincorporated landlords and sole traders.
Step 1: Confirm Your Qualifying Income
Qualifying income includes UK property income and self employment turnover, but excludes income already run through a limited company. Landlords with both a rental portfolio and a separate sole trade business must combine both income streams when checking against the threshold, and file separate quarterly updates for each business.
Step 2: Choose MTD Compliant Software
HMRC no longer accepts quarterly updates through its website. All submissions must go through authorised MTD software, whether a full accounting package or a simple spreadsheet linked via bridging software. Landlords should select software that can categorise income and expenses correctly, store digital records, and submit directly to HMRC without manual re-entry.
Step 3: Set Up Digital Record Keeping
Every transaction affecting rental income and expenses must be recorded digitally as it happens, not reconstructed at quarter end. This includes rent received, mortgage interest, letting agent fees, repairs, insurance and any other allowable costs, all logged with dates and categories that map to HMRC’s requirements.
Step 4: Know Your Quarter Dates and Deadlines
By default, quarters follow the tax year, though landlords can elect calendar quarters instead, and the filing deadline stays the same either way.
| Quarter | Standard tax period | Calendar period | Filing deadline |
|---|---|---|---|
| 1 | 6 April to 5 July | 1 April to 30 June | 7 August |
| 2 | 6 July to 5 October | 1 July to 30 September | 7 November |
| 3 | 6 October to 5 January | 1 October to 31 December | 7 February |
| 4 | 6 January to 5 April | 1 January to 31 March | 7 May |
Step 5: Submit Each Quarterly Update
Each quarterly update is a running summary of income and expenses for the period, submitted cumulatively through your chosen software. Landlords with both a property business and a sole trade must submit separately for each, meaning up to eight quarterly submissions a year for landlords running both.
Step 6: File the Final Declaration
After the fourth quarterly update, landlords must submit an MTD tax return, sometimes called the final declaration, confirming total income and any adjustments for the year. This is due by the usual Self Assessment deadline of 31 January following the end of the tax year, and replaces the old Self Assessment return entirely.
Step 7: Understand the Penalty Points System
HMRC has replaced fixed late filing fines with a points based system for MTD. Landlords receive one penalty point for each missed quarterly or annual deadline, and once four points accumulate for quarterly filers, a £200 penalty is charged automatically. Every further missed deadline after that threshold triggers another £200 penalty on top of the running points. Points expire after 12 months of full compliance for quarterly filers, though they cannot be cleared while any submissions remain outstanding.
Importantly, HMRC has confirmed a soft landing for the first mandatory year, meaning no penalty points apply for missed quarterly updates in 2026/27 for landlords who joined MTD on 6 April 2026. Points based penalties for quarterly filers begin from 6 April 2027, with the first affected deadline being 7 August 2027.
Step 8: Build a Repeatable Quarterly Routine
Rather than treating each quarter as a fresh scramble, landlords should build a simple recurring routine.
- Reconcile bank transactions weekly or monthly rather than waiting until the deadline
- Keep digital copies of invoices and receipts as they arrive
- Review categorised expenses before each quarter closes to catch missing entries
- Diarise deadlines a week in advance rather than relying on memory
- Use software that flags incomplete records before submission
Common Mistakes to Avoid
Many landlords underestimate how much administrative discipline MTD requires compared to a single annual return. Frequent errors include mixing personal and rental transactions in the same account, missing the calendar quarter election deadline, and assuming furnished holiday let income is excluded when in some cases it still counts toward qualifying income. Landlords who wait until the week before a deadline to reconcile records are also the most likely to miss submissions entirely, triggering avoidable penalty points once the soft landing period ends.

FAQs
Do I need to file quarterly if my rental income is below £50,000?
Not yet. The £50,000 threshold applies from April 2026, dropping to £30,000 in April 2027 and £20,000 in April 2028.
Can I still use HMRC’s website to file my quarterly update?
No. All quarterly updates and the final declaration must be submitted through authorised MTD compatible software.
What happens if I miss a quarterly deadline in 2026/27?
There is a soft landing for the first mandatory year, so no penalty points apply for missed quarterly updates in 2026/27 for landlords who joined on 6 April 2026.
How many points trigger a penalty for quarterly filers?
Four points trigger an automatic £200 penalty, with each further missed deadline adding another £200 charge.
Do I file separately for rental income and self employment?
Yes. A separate quarterly update is required for each qualifying business, meaning up to eight submissions a year if you have both.
