MTD for non-resident landlords with UK property

Someone I’ll call Elena moved to Lisbon a couple of years back and kept her flat in Manchester, renting it out. She’s a composite, really, stitched together from a few expat threads, but her situation is common enough: British-ish ties, a UK property still earning, and a nagging worry about whether this Making Tax Digital thing applies to someone who doesn’t even live in the country anymore. The honest answer is: maybe, and it hinges on something you’d never guess. Whether she’s got a National Insurance number.

Bear with me, because this is genuinely one of the more confusing corners of the whole regime, and most guides get it half-right at best.

Only your UK income counts

First, a clean bit of good news. If you’re non-resident, only your UK-source income counts towards the MTD threshold. Elena’s Manchester rent goes in the sum. If she also owned a place in France or picked up freelance work in Portugal, none of that touches her UK MTD position. That’s different from a UK resident, who has to total up their worldwide rents. For a non-resident, HMRC only cares about what’s taxable here.

So if Elena’s UK flat brings in, say, £38,000 gross, that’s her number. Above the £30,000 threshold that kicks in from April 2027, below the £50,000 one for 2026. Which sets up the real question.

The National Insurance number twist

Here’s the part I had to read three times to be sure I had it straight. Non-residents get two separate let-offs, and they work completely differently.

The first is temporary. Non-residents who’d otherwise be pulled in have a residence-based exemption that runs out in April 2027. After that, if your UK qualifying income is over the threshold, the general rules catch up with you.

The second is permanent, and it’s the one that decides Elena’s fate: if you don’t have a UK National Insurance number, you’re outside MTD indefinitely. No expiry. You carry on filing an ordinary annual Self Assessment return for your UK rental income, exactly as before. This exemption lives in the Income Tax digital-obligations regulations, and it has no end date bolted onto it.

So the practical fork is this. Elena worked in the UK for years before leaving, so she almost certainly has an NI number, which means the permanent exemption doesn’t save her; once the temporary residence exemption expires in April 2027, she’s in MTD if her UK rent is over the threshold. But someone who’s never lived or worked in the UK, a foreign investor who bought a Leeds flat purely as an investment, typically won’t have an NI number, and they’re covered by the permanent exemption for the foreseeable. Same UK flat, same rent, opposite outcome, decided by a number most people never think about.

There’s also a deferral worth knowing about. Non-residents who complete the residence pages of their tax return (the SA109) may be able to defer their MTD start by a year, into April 2027, if they expect their circumstances to keep changing. It was announced at the Spring Statement 2025 and the detail landed later. If your residency status is genuinely in flux, that’s worth raising with an accountant rather than assuming either way.

MTD doesn’t replace the NRLS. They run side by side.

This is the other thing people get tangled in, so let me separate the two cleanly.

If you’re a non-resident landlord, you’re probably already familiar with the Non-Resident Landlord Scheme, the NRLS. Under it, your letting agent (or your tenant, if there’s no agent) deducts basic-rate tax from your rent before it reaches you, unless you’ve got approval from HMRC to receive it gross. That’s a withholding system, and MTD changes absolutely nothing about it. The NRLS keeps running exactly as it did.

What that means in practice, if Elena ends up in both: her agent keeps withholding under the NRLS, and separately she keeps digital records and files quarterly under MTD. Two systems, same rental income, doing different jobs. The tax the agent withheld gets credited back when she does her final declaration, so if they took £7,000 across the year but her actual bill was £5,000, she’s owed the £2,000 back. If she’s got NRL1 approval to receive rent gross, there’s no withholding to reconcile in the first place and the MTD side just works like it does for anyone else.

One small mercy: if she has NRL1 approval, that reconciliation headache disappears, so it’s worth having in place before the first filing cycle if she qualifies.

What non-residents actually need from software

Assuming you are caught, the mechanics of MTD are identical to a UK resident’s. Same quarterly deadlines, 7 August, 7 November, 7 February, 7 May. Same final declaration. Same digital-records requirement.

The wrinkle is the NRLS reconciliation. If your agent withholds tax under the scheme, you want software (or an accountant) that can handle crediting that withheld tax at the final declaration, because those quarterly NRLS statements from your agent need to feed into your year-end. Not every tool is built with the non-resident case in mind, and it’s the sort of thing that’s easy to overlook until reconciliation time. Our comparison notes which products cope with the wrinkles, and the selectorfactors in whether you’re letting through an agent.

And if you’re still unsure whether you’re even in scope, the main MTD guide lays out the threshold basics before any of the non-resident complications come into play.

Common questions from overseas landlords

I live abroad and have no UK NI number. Am I in MTD?

No, not currently. If you don’t hold a UK National Insurance number, you’re covered by a permanent exemption with no expiry date, and you continue reporting your UK rental income through an ordinary annual Self Assessment return.

I have a UK NI number from when I lived there. Does that change things?

Yes. The permanent no-NI-number exemption doesn’t apply to you. You may still get a temporary residence-based exemption that runs until April 2027, but after that, if your UK qualifying income is over the threshold, you’ll need to comply.

Does my overseas rental income count towards the UK threshold?

Not if you’re non-resident. Only your UK-source income counts. Overseas property income is ignored for your UK MTD threshold. (It’s the reverse for UK residents, who aggregate their worldwide rents.)
