Both a landlord and self-employed? How MTD adds up

This is the situation that catches the most people out. If you rent out a property and do some self-employed work, HMRC doesn’t test them separately — it adds them together. That combined figure is what decides when Making Tax Digital starts for you, and it pulls a lot of people into the net a year or two earlier than they expect.

The maths that surprises people

Qualifying income is gross rental income plus gross self-employment turnover — both before expenses. So:

• £22,000 of rent + £12,000 of freelance work = £34,000 → mandated from April 2027.
• £30,000 of rent + £25,000 of trade = £55,000 → mandated from April 2026.

In both cases neither income alone would have hit that threshold. If you co-own the property, it’s your share of the rent that goes into the sum — so two co-owners with different side businesses can land in different years. The calculator does this arithmetic for you, for both people at once.

Two income sources means two sets of updates

Quarterly updates are filed per income source. Property and self-employment are separate sources, so you send a set for each — then one final declaration that pulls everything together at year end. Same deadlines (7 Aug, 7 Nov, 7 Feb, 7 May), double the filing.

That's the practical argument for one tool that handles both: two tools means two subscriptions, two logins and two chances to miss a deadline.

Tools that file both

• Xero — £7 / month. Landlords whose accountant already works in Xero — the most widely used platform in UK practices.
• QuickBooks — £10 / month. Phone-first bookkeeping with strong automation and AI categorisation.
• RentalBux — £0–£4.50 / month. Co-owning couples who want property and self-employment income handled together in one filing.
• ApariPro — £12 / month. Landlords with messy, multi-source income who want the whole Self Assessment handled in one place — APARI was the first vendor ever to file an MTD Income Tax return to HMRC.

Watch out for two traps. FreeAgent handles both income types but needs a separate account for each — fine, but it's two subscriptions in practice. Landlord Studio and Hammock are property-only, so they can't file your trade at all no matter how good they are at the rental side.

If you're also a co-owner

Combining the two hardest cases — joint property plus self-employment — is where tool choice really narrows. You need ownership splitting and self-employment filing in the same product. Read the jointly owned property guide for how the split works, then let the picker filter to tools that do both.

What to do now

• Add your gross rent (your share) and gross turnover together — that's your qualifying income.
• Check it against the thresholds with the calculator.
• Choose one tool that files both sources if you can.
• Remember it's gross, not profit — high-turnover, low-margin trades get caught early.
