"Do I really have to file every three months now?"
If you let out property in the UK, that is the question worth answering early. Making Tax Digital for Income Tax (often shortened to MTD for Income Tax, or MTD ITSA) changes how many landlords keep records and report to HMRC. It is not a new tax. It is a new way of filing: digital records plus quarterly updates in place of one annual Self Assessment return.
The catch is that it does not land for everyone at once, and the trigger is your gross rent, not your profit. Here is who is in, from when, and what you will actually have to do.
What MTD for Income Tax actually is
Three things replace the once-a-year routine:
- Digital records. You keep income and expenses in MTD-compatible software (or a bridging tool linked to a spreadsheet), not on paper or in your head.
- Quarterly updates. Four times a year you send HMRC a running total of your property income and expenses.
- A final declaration. After the tax year ends you confirm the full picture, claim reliefs and allowances, and finalise your bill. This replaces the Self Assessment return, but the 31 January deadline and payment dates stay the same.
Who's caught, and from when
Mandation is phased by "qualifying income" - your gross income from self-employment and property added together, before any expenses. For a pure landlord that means gross rent.
| Qualifying income | You must use MTD from |
|---|---|
| More than £50,000 | 6 April 2026 |
| More than £30,000 | 6 April 2027 |
| More than £20,000 | 6 April 2028 |
The £50,000 and £30,000 start dates are confirmed by HMRC. The £20,000 threshold from April 2028 was announced at the Autumn Budget on 30 October 2024. (Source: gov.uk, "Check if you need to sign up for Making Tax Digital for Income Tax".)
HMRC works out which band you are in from your most recent filed return. So the return you file by 31 January 2026 (for the 2024-25 tax year) is what tells HMRC whether you join the first wave in April 2026.
The trap: it's gross rent, not profit
This is where landlords get caught out. The threshold looks at turnover, not what you keep.
Say a buy-to-let brings in £4,400 a month, so £52,800 a year. After mortgage interest, letting fees, insurance and repairs your actual taxable profit might be £9,000. You are still in the first wave from April 2026, because £52,800 of gross rent is over the £50,000 line. A thin margin does not get you out of it.
The same logic combines your income streams. If you have £30,000 of rent and £25,000 from freelance work, your qualifying income is £55,000, so you are in from April 2026 even though neither source on its own clears £50,000.
The quarterly timeline in practice
Once you are in, the tax year is split into four standard quarters. Each update is cumulative, a year-to-date total, and each has a fixed deadline on the 7th:
| Quarter covers | Update due by |
|---|---|
| 6 Apr to 5 Jul | 7 August |
| 6 Apr to 5 Oct | 7 November |
| 6 Apr to 5 Jan | 7 February |
| 6 Apr to 5 Apr | 7 May |
These updates are rough running totals. You are not claiming every allowance or finalising anything at this stage, so a small slip in one quarter can be corrected later. The real accuracy comes at the final declaration, due by 31 January after the tax year ends, the same date you know today.
If the standard quarters are awkward, you can elect for calendar quarters (to 30 June, 30 September, 31 December and 31 March) in your software. The deadlines still fall on the 7th of the following month.
A worked example
Priya owns two rental flats. Flat A brings in £18,000 a year, Flat B £16,800. Her gross rent is £34,800 and she has no other trade or self-employment.
- She is over £30,000 but under £50,000, so she is not in the April 2026 wave. She joins from 6 April 2027.
- From that date she keeps digital records and sends four updates a year. Her first, covering 6 April to 5 July 2027, is due by 7 August 2027.
- She still files a final declaration for 2027-28 by 31 January 2029, and her payment dates do not change.
If Priya's rents rose and her gross figure crept over £50,000 on the return HMRC checks, she would instead be pulled into the April 2026 start.
Jointly owned property
Each owner counts only their share. A couple who own a property 50/50 and receive £70,000 of rent between them each have £35,000 of qualifying income. Neither is in the £50,000 April 2026 wave; both join from April 2027 under the £30,000 threshold. Look at each person's total across all their properties and trades, not the household's combined figure.
Exemptions and edge cases
You may be exempt if it is not reasonably practicable for you to use digital tools (for example due to age, disability, or a location with no reliable internet), or if HMRC already treats you as digitally excluded. Trustees, personal representatives and some other cases have their own rules. If your qualifying income sits at or below the lowest threshold, you stay on Self Assessment as normal for now.
How to get ready
You do not need to do everything today, but a few steps make the switch painless:
- Know your number. Add up gross rent (and any self-employment turnover) to see which threshold and start date apply to you.
- Check your last return. HMRC uses it to decide your wave, so make sure it is accurate.
- Pick software early. Choose an MTD-compatible package, or a bridging tool if you like your spreadsheet, and start recording income and expenses digitally before your start date.
- Sign up when eligible. You can join voluntarily ahead of mandation on gov.uk to test the process on a real year.
Keeping clean, up-to-date records all year, rather than a shoebox reconciled every January, is the real shift MTD asks of landlords. Logging rent and expenses as they happen makes each quarterly update a five-minute job instead of a scramble.
This is general information, not tax or financial advice. Thresholds and dates are correct as of July 2026; check the current rules on gov.uk before you act.
