MTD when you're a landlord and self-employed
Making Tax Digital doesn't look at your rental income or your business income separately — it adds them together. A landlord with £30k of rent and a £25k side business is over the £50,000 line and mandated from April 2026, even though neither income alone would qualify. Here's exactly how the combined rules work, and how to run both from one spreadsheet.
How the threshold really works
The test is your combined gross income from self-employment and property for the tax year — turnover, not profit, before any expenses. If the total exceeds the threshold, you're in for both income types at once:
| Combined gross income | You're in MTD from |
|---|---|
| Over £50,000 | April 2026 |
| Over £30,000 | April 2027 |
| Over £20,000 | April 2028 |
What being “in” actually means for you
- Digital records for both income types — kept in software or a spreadsheet with digital links.
- Quarterly updates for each income source — a landlord-plus-sole-trader files two updates per quarter (one property, one trade): eight submissions a year, by 7 August, 7 November, 7 February and 7 May.
- A final declaration replacing the Self Assessment return, due 31 January as now.
Joint property? There's a wrinkle for that too
Own a rental jointly (with a spouse, say)? Each owner reports their share in their own MTD records. In practice that means splitting every rent receipt and expense line by your ownership percentage — trivial in a spreadsheet (one formula column), fiddly in many apps.
Why one spreadsheet beats two apps
Most landlord software handles property only; most bookkeeping apps handle trade only. Run both and you're paying two subscriptions, learning two systems, and still stitching the totals together in January. A spreadsheet holds both income types side by side — one tab per source, HMRC's categories on each, your joint-ownership split as a formula — and HMRC explicitly permits spreadsheet records provided the figures reach them through bridging software with a digital link.
Quick answers
Do I add rental and self-employed income together for the threshold?
Yes — the qualifying-income test is the combined gross total of both for the tax year.
Do I file one quarterly update or two?
One per income source — so a landlord with a trade files two each quarter, eight a year, plus the final declaration.
Is it profit or turnover that counts?
Gross income (turnover/rents before expenses). Profit is irrelevant to the threshold.
What about dividends, pensions or a PAYE salary?
They don't count toward the threshold — only self-employment and property income do.
My rental is jointly owned — whose income is it?
Your share counts toward your threshold; each joint owner keeps digital records of their own share.
Both incomes. One spreadsheet. Sorted.
SheetMTD structures property and self-employment records side by side in Google Sheets, in HMRC's categories, with joint-ownership splits by formula — free to set up, built by a UK chartered accountant's practice.
