A landlord rang me last week, genuinely worried, because a forum post had told him he was breaking the law by not filing quarterly. He has one flat that brings in £9,600 a year. He is nowhere near being in scope, and will not be for years. Across the conversations I have had since MTD for Income Tax went live on 6 April 2026, the single biggest source of stress among landlords is not the software. It is not knowing which threshold they fall into or which date applies to them.
So this is a landlord-focused walk through scope and timing. If you let property in the UK and you want a straight answer to “is this me, and when,” start here. The mechanics of running MTD once you are in scope are covered in our broader piece, MTD for Income Tax: what UK sole traders and landlords need to do now; this post is about working out whether you are in the room at all.
The three thresholds, and the dates that go with them
MTD for Income Tax is being phased in by income band. The band you fall into decides your start date.
| Qualifying income | MTD for Income Tax start date |
|---|---|
| Over £50,000 | 6 April 2026 (already live) |
| £30,000 to £50,000 | 6 April 2027 |
| £20,000 to £30,000 | 6 April 2028 |
| Under £20,000 | No confirmed mandation date |
The official, up-to-date timetable lives in HMRC’s MTD for Income Tax collection ↗. Treat any forum or social post that contradicts those dates as wrong until you have checked the source.
What “qualifying income” means for a landlord
This is where most landlords trip up. Qualifying income is your gross income, before any expenses, from self-employment plus property. Three points matter for property in particular.
It is rent received, not profit. A landlord with £36,000 in annual rent and a £14,000 mortgage interest bill has qualifying income of £36,000, not £22,000. The interest, agent fees, repairs and other costs do not reduce the figure used to test the threshold.
It is the combined total across all your lettings. Three flats at £14,000 each is £42,000 of qualifying income, even though no single property crosses £30,000. You count the portfolio, not the individual unit.
It is added to any self-employment income. If you let a property for £24,000 and also do consultancy as a sole trader for £30,000, your qualifying income is £54,000. That puts you over £50,000 and in scope from April 2026, even though neither activity alone would have triggered it.
If you are not certain where you land, HMRC has a short eligibility tool at find out if and when you need to use MTD for Income Tax ↗. It takes about two minutes and is the authoritative answer for your situation.
Where landlords sit on the timeline
Most accidental landlords, those with one rented flat or a single buy-to-let, sit below £30,000 and will not be mandated until April 2028 at the earliest. The cohort feeling real pressure right now is the portfolio landlord, or the landlord with a separate trade, whose combined gross income clears £50,000.
What landlords have to actually keep
Once you are in scope, the requirement is digital record keeping plus quarterly updates. For property, that means:
- Recording rental income digitally as it arrives, per property income source
- Recording allowable expenses digitally: repairs, agent fees, insurance, ground rent, service charges and so on
- Sending a quarterly summary to HMRC through compatible software
- Submitting a final declaration after the tax year, which replaces the property pages of the old Self Assessment return
The full requirement is set out in HMRC’s guidance on using MTD for Income Tax ↗. A spreadsheet you tidy up once a year before the January deadline does not meet this standard on its own.
The detail that catches landlords out: separate income sources
If you have both a property business and a trade, HMRC treats them as separate income sources inside your MTD return. The same applies if you have UK property and foreign property. You keep records separately and the quarterly update reflects each source.
This is the single most common reason landlords pick the wrong software. A tool built purely for sole-trader bookkeeping may not cleanly handle a property income source alongside a trade. Before you commit, check that the product on HMRC’s recognised software list ↗ supports property and, if relevant, multiple income sources in one return. Not all of them do.
If your accountant files for you
Plenty of landlords never touch the software themselves; their accountant handles it. That still works under MTD, but the sign-up route is different. Your accountant signs you up as their client through the agent process described in HMRC’s guidance on signing up a client for MTD for Income Tax ↗. The thing to confirm now, not in July, is that your accountant is set up for it and is using software that supports property income. Get that confirmation in writing.
A practical readiness path for landlords
You do not need to panic, but you do need to know your date and prepare for it. Here is the order I suggest, whichever band you are in.
If you are over £50,000 (in scope now): you should already be keeping digital records from 6 April 2026. Your first quarterly update covers 6 April to 5 July 2026 and is due by 5 August 2026. If you have not started, the priority this month is choosing software, signing up through it, and entering income and expenses from 6 April onward.
If you are £30,000 to £50,000 (April 2027): you have a year, and that is a gift. Use it to switch to digital record keeping voluntarily during the 2026-27 tax year, so that when mandation hits you are simply continuing a habit rather than starting one under a deadline.
If you are £20,000 to £30,000 (April 2028): no immediate action is required, but the direction of travel is clear. Moving rent and expenses out of an annual spreadsheet and into a monthly digital rhythm now will make the eventual transition a non-event.
The pattern I see again and again is that the software is rarely the hard part. The hard part is the underlying record keeping. If your rental admin lives in a shoebox of receipts and a once-a-year reckoning with your accountant, MTD turns a private mess into a quarterly deadline. We wrote about that wider problem in signs your business has outgrown its software, and the move from spreadsheets to a proper system in from spreadsheet to software.
Frequently asked questions
Does MTD for Income Tax apply to a landlord with one property under £20,000?
No. There is currently no confirmed mandation date for qualifying income under £20,000. You continue with Self Assessment as normal unless and until HMRC announces a date and threshold that includes you.
Is the threshold based on rent or profit?
Rent received, before expenses. Mortgage interest, agent fees and repairs do not reduce the figure used to test the threshold, even though they reduce your taxable profit.
I own properties jointly with my spouse. How is income counted?
Each owner counts their own share of the gross rental income towards their personal qualifying income. A jointly owned property generating £40,000, split equally, gives each owner £20,000 of qualifying income from that property, before adding any other income.
Do I count UK and overseas property together?
They are both property income, but HMRC treats UK property and foreign property as separate income sources within your MTD return. Both gross figures count towards your qualifying income for the threshold test.
What if my rental income varies year to year?
HMRC assesses qualifying income based on your most recent finalised Self Assessment return. If a one-off rent rise or a property sale pushes you over a threshold in a single year, check the eligibility tool, because the rules on which year is tested matter and are best confirmed against the source.
When is the first quarterly update due for an in-scope landlord?
For landlords mandated from 6 April 2026, the first quarterly update covers 6 April to 5 July 2026 and is due by 5 August 2026. A final declaration for the year follows by 31 January after the tax year ends.
Worth a conversation?
If MTD for Income Tax has made you look hard at how you actually track rent, expenses and tenants, and the answer is “badly, across three spreadsheets and a notebook,” that is the kind of operational mess I help small property businesses sort out. For most landlords an off-the-shelf MTD product from the HMRC list is the right answer, and I will tell you so plainly. For landlords running a larger portfolio where the admin has outgrown spreadsheets, the underlying system is often the real fix; we covered the reporting side of that in custom database reports for UK small businesses.
Get in touch and tell me what your setup looks like. I will give you a straight answer on whether software off the shelf is enough or whether the layer underneath needs sorting first.
