Selling a UK House From Abroad: The 2026 Non-Resident Guide

By Lisa Hayes · 21 August 2026

If you live abroad and sell a UK property, you have to tell HMRC within 60 days of completion. Not 30. Not by the following January. Sixty days — and that duty applies even if you made a loss, even if there is no tax to pay at all, and even if you already file a UK Self Assessment return.

As a non-resident you are usually only taxed on the growth in value since 5 April 2015, at 18% or 24% depending on your UK income. That part is often manageable. What catches people out is everything else: proving your identity to HM Land Registry from Auckland, getting a transfer deed witnessed in Dubai, and discovering three weeks before completion that your buyer's solicitor will not accept a scanned passport.

Do I actually have to pay UK tax if I sell my UK house while living abroad?

Yes, potentially — and separately from that, you almost certainly have to report it.

Those are two different obligations and people conflate them constantly. Since 6 April 2015, the UK has taxed non-residents on gains from UK residential property. Since 6 April 2019, that extended to all UK land and property, including commercial premises, agricultural land and mixed-use buildings such as a flat above a shop. HMRC's own guidance is blunt about it: if you are not resident in the UK, you must report disposals of UK property or land even if you have no tax to pay, even if you made a loss, and even if you are registered for Self Assessment.

That last one is the trap. Plenty of expats still file a UK tax return because they have rental income, and they reasonably assume the property sale will just go in that return like it would for a UK resident. It does go in that return. But it also needs a standalone return within 60 days, filed first. The Self Assessment entry does not replace it.

• 60 daysto report and pay after completion
• 5 April 2015the date your residential gain is measured from
• 18% / 24%CGT rates on residential gains, 2026/27
• £3,000annual exempt amount, 2026/27

The 60-day rule: the deadline that catches most expats out

The clock starts on the completion date — the day ownership actually transfers — not exchange, and not the day the money reaches you. For completions on or after 27 October 2021 you get 60 days to both report and pay.

You will still find UK property guides, including some written by large house-buying firms, quoting a 30-day deadline. That figure was correct for completions between 6 April 2020 and 26 October 2021. It has been wrong for over four years. If you are reading a page that still says 30 days, treat everything else on it with suspicion too.

How much capital gains tax will I pay?

For residential property in the 2026/27 tax year, the rates are 18% if the gain falls within your remaining UK basic rate band, and 24% above that. Your first £3,000 of gains in the tax year is covered by the annual exempt amount, assuming you have not used it elsewhere.

Working out which band applies is fiddlier for non-residents than for people at home, because you add together your taxable UK income for the year and see how much basic rate band is left. If you moved abroad years ago and have no UK income at all, you may have most of the band available, which pushes a good chunk of the gain into the 18% slice.

A worked example. You bought a terraced house in Sheffield in 2008 for £120,000, moved to Singapore in 2013, and sell in 2026 for £240,000. Your gain over the whole period is £120,000 — but as a non-resident you are looking at the growth since 5 April 2015. If the house was worth £150,000 on that date and you have spent £6,000 on selling costs and a new roof since, the chargeable gain is closer to £84,000. That is a materially different number, and it is why the valuation date matters so much.

One practical warning: HMRC publishes a non-resident CGT calculator, and it is genuinely useful, but it will not work for you if you were a higher or additional rate taxpayer, if the grounds exceed half a hectare, if you used part of the property for business, or if you are selling only part of your interest. In those cases you need the numbers done properly rather than run through a web form.

Three ways to calculate your gain — and why the default is not always best

If you owned the property before 6 April 2015, you get a choice. Most people never learn this, take the default, and occasionally pay more than they needed to.

You do not need a valuation carried out back in April 2015 to use rebasing. You can commission one retrospectively. What helps enormously is any record of the property's condition at the time — old listing photographs, a survey, an insurance schedule, a letting agent's inventory. Retrospective valuations are a judgement call, and evidence narrows the range.

If you want certainty before you file, form CG34 lets you ask HMRC's Shares and Assets Valuation team to check your figure. Two caveats: it can only be requested after the disposal, and it takes at least three months. That is longer than your 60-day window, so it is a comfort measure for the Self Assessment stage rather than a way to delay the return.

What if it used to be my home? Private Residence Relief and the 90-day rule

This is where a lot of expat sellers get a very pleasant surprise.

Private Residence Relief still exists for non-residents, but it works differently. For a tax year in which you were non-resident, you generally only get relief for the property if you, your spouse or your civil partner spent at least 90 midnights in that home during that year. You also have to formally nominate it as your only or main home when you report the sale — the nomination is not automatic, and HMRC will not do it for you.

Ninety nights is not a huge ask if you have been coming back for summers or Christmas, but it does mean keeping evidence. Flight records, ferry bookings, utility usage, a diary. Rough recollection is not going to survive an enquiry.

On top of that, you get full relief for the final nine months of ownership if you qualify for relief in any period. That extends to 36 months if you are disabled or in long-term residential care. Relief is restricted, though, if in a given year you let part of the home out (a lodger is fine, a separate let is not), used part exclusively for business, or the grounds including all buildings exceeded 5,000 square metres.

Our wider guide on how to legitimately reduce capital gains tax when selling a UK property covers the reliefs that apply to UK residents as well, and there is a companion piece on selling a second home and the CGT position if the property was never your main residence.

How to report the sale: the actual steps

1. Set up a Capital Gains Tax on UK property account. This is separate from any Government Gateway account you already have for Self Assessment. Do it before completion, not after — new accounts sometimes need identity checks that take days.
2. Gather the numbers. Address and postcode, acquisition date, exchange date, completion date, value when acquired, sale price, costs of buying, selling and improving, and property type.
3. Choose your calculation method and, if you are rebasing, obtain the 5 April 2015 valuation.
4. File the return. Online through the account, or by post using the Capital Gains Tax on UK property form if you genuinely cannot report online.
5. Pay. HMRC issues a 14-digit reference beginning with "x" once you have filed. You cannot pay without it, so do not leave filing until day 58.
6. Repeat the disposal in your Self Assessment return for the relevant tax year, if you file one.

Using an accountant? The sequence matters and it trips people up. You must create the property account first, then give your agent the account number and your country of residence so they can send you an authorisation link by email, which you then accept. An agent cannot open the account for you. If your accountant is waiting on you and you are waiting on your accountant, sixty days evaporates quickly.

What happens if you miss the deadline

Penalties can be appealed where you have a reasonable excuse. "I didn't know" is not usually one. "I was abroad" definitely is not. If you have already blown the deadline, file immediately anyway — the later penalties are calculated from the filing date, so every week you delay compounds the problem rather than freezing it.

Proving who you are: the problem nobody warns you about

Here is the part that derails more overseas sales than tax ever does.

HM Land Registry will not register a transfer without satisfactory evidence of identity for anyone who is not represented by a UK conveyancer. The rules live in HM Land Registry's Practice Guide 67. In the ordinary run of things, your UK solicitor verifies you in person and that is the end of it. From 6,000 miles away, in person is not happening.

Your realistic options:

• Form ID1 verified by an overseas lawyer or notary. Where you live abroad and a UK conveyancer cannot verify you, section B or section C of form ID1 can be completed and signed by a lawyer or notary public qualified to practise in your country of residence. This is the standard route and it works — but notary appointments in some jurisdictions take weeks, and notary fees can run into hundreds of pounds.
• Digital identity verification. Section C of form ID1 now allows identity to be verified digitally in line with HM Land Registry's digital identity standard. Ask your solicitor early whether their firm offers this. If they do, it can turn a three-week problem into a twenty-minute one.
• Form ID3. Useful only in narrow circumstances: both you and the person verifying you must hold a full UK passport, and they must have known you for at least a year. Fine for a British expat with a British neighbour abroad. Useless for most people.

My advice, and I give it to every overseas seller who calls us: raise identity verification in your first conversation with a solicitor, before you have even accepted an offer. Ask them directly what route they will use and how long it takes in your country. A firm that shrugs at that question is the wrong firm.

Signing from abroad: witnesses, deeds and time zones

The transfer deed (usually form TR1) is a deed, which means your signature must be witnessed by someone physically present who then adds their own name and address. That witness should be an independent adult — not your spouse, not the buyer, not anyone with an interest in the sale. Practically, that means a colleague, a neighbour, or the notary you are already sitting with.

Then the paper has to get back to the UK. Courier it, do not post it. International post loses documents, and a lost deed on completion day is a very expensive afternoon.

If you cannot reliably sign documents at short notice — because you are offshore, deployed, travelling for work, or in a country with slow legalisation processes — consider a power of attorney appointing someone in the UK to sign on your behalf. It needs to be drafted by a UK solicitor, executed correctly, and in place well before exchange. Do not improvise this from a template found online; a defective power of attorney is discovered at the worst possible moment.

Small thing that causes real friction: completion happens on a UK working day, and money must move through the UK banking system before it closes. If you are in Sydney, that is the middle of your night. Tell your solicitor in advance who they can reach and how, and give them authority to proceed without ringing you at 3am for a decision.

If the property is held by an overseas company

Different regime entirely, and a stricter one. An overseas entity that owns UK property must be registered with Companies House on the Register of Overseas Entities and must supply its Overseas Entity ID to the land registry when it sells or transfers. Without it, a restriction on the title blocks the disposition. You cannot sell.

Worse, the ID becomes invalid if the entity misses its annual update statement. Companies discover this at the point of sale, which is precisely when there is no time to fix it. If you own UK property through a non-UK company, check the entity's filing status now rather than when a buyer is waiting.

Non-resident companies also pay Corporation Tax on property gains rather than CGT, reported on a Corporation Tax return, and must register for it if they do not already file.

If the house has been let out

Most expats who kept a UK property have let it, which adds layers.

While it was let, you should have been inside the Non-resident Landlords Scheme — under which your letting agent or tenant deducts basic rate tax from the rent unless HMRC approved an application (form NRL1) to receive it gross. If nobody ever mentioned this to you, get it looked at before you sell, because a disposal tends to prompt HMRC to look at the whole picture.

Letting also eats into Private Residence Relief, and it removes final-period relief for any part of the property you never lived in.

Then there is the tenant. Selling with someone living there is entirely possible, but it narrows your buyer pool sharply to investors, and following the tenancy reforms most sellers now find vacant possession takes longer to achieve than they expect. We cover the options in detail in our guide to selling a tenanted property. The short version: decide early whether you are selling with tenants in situ or vacant, and price accordingly. Trying to switch strategy halfway through costs months.

Estate agent or cash buyer? Choosing a route you can run remotely

Distance changes the maths. A sale that would be mildly annoying to manage from Manchester can be genuinely unworkable from Muscat, and the cheapest route on paper is not always the cheapest once you count flights, empty-property insurance, council tax on an empty home and four months of your attention.

The alternative is a genuine cash purchase. A reputable cash house buyer will typically offer meaningfully below market value in exchange for speed and certainty, no chain and a completion date you choose. For an overseas seller with a vacant property, a repossession risk, or a deadline tied to a visa or a purchase abroad, that trade is sometimes obviously worth it — and sometimes obviously not.

Be careful here, because this corner of the market contains both excellent operators and some genuinely poor ones. The behaviour to watch for is a strong initial offer that is reduced late in the process, once you are committed and geographically unable to walk away easily. Overseas sellers are targeted for exactly that reason. Get the offer basis in writing, ask what would cause it to change, and read our breakdown of the best house buying companies and how to tell them apart before you agree to anything. If speed is the priority, our guide to selling a house fast sets out the realistic timescales.

Whichever route you take, start from an honest number. Online estimates are notoriously unreliable for properties the owner has not seen in years, and a stale mental picture of your old street is not a valuation. Our guide to what your house is actually worth explains how to sanity-check a figure from a distance, and if any of the terminology in your solicitor's emails is unfamiliar, property jargon explained will save you some Googling.

Getting the money out

The UK does not withhold a slice of your sale proceeds at completion the way some countries do. The full net figure lands in your solicitor's client account and then goes wherever you direct it.

Two practical points. First, keep a UK bank account open if you possibly can. Solicitors are far more comfortable sending completion funds to a UK account in the seller's own name, and some firms will not send large sums overseas at all without extra checks. Closing your UK account when you emigrate is one of those decisions that seems tidy at the time and creates a headache years later.

Second, if you do need the money converted, high-street banks are rarely competitive on large transfers, and the spread on a six-figure sum is not trivial. Compare a specialist currency broker. And do not treat the exchange rate as an afterthought — on a £250,000 sale, a two-cent move is real money.

Will I be taxed twice?

Possibly not. Many of the UK's double taxation treaties determine which country has the right to tax a gain on UK land, and where a treaty exempts the gain from UK tax you can claim that relief — but you still have to file the relevant UK return to claim it. Silence is not a claim.

Your country of residence may also tax the gain on its own rules, sometimes measuring it from the original purchase price rather than a 2015 rebasing, and sometimes at a higher rate than the UK. Credit for UK tax paid is common but not universal. If the sums are large, this is the point at which paying for an hour of cross-border tax advice pays for itself several times over.

One more wrinkle worth knowing about: temporary non-residence. If you leave the UK, sell, and then return within a relatively short period, anti-avoidance rules can drag a gain that escaped non-resident CGT back into charge in the year you come home. If there is any prospect of you returning to the UK within five years, get advice before you complete rather than after.

A realistic timeline

The mistakes I see most often

• Assuming Self Assessment covers it. It does not. File the 60-day return regardless.
• Leaving identity verification until the solicitor asks. By then you have already lost two weeks.
• Taking the rebasing default without checking the alternative. On properties bought shortly before 2015, time apportionment sometimes wins.
• No 2015 evidence. If you owned the property in April 2015, dig out photographs, surveys and old listings now. They will be harder to find in five years.
• Closing the UK bank account. Reopening one from abroad is far harder than keeping one ticking over.
• Believing the first offer is the final offer. Especially from firms that know you cannot easily come back and argue in person.
• Signing a long sole agency agreement remotely. Twelve-week tie-ins with an agent you have never met are a bad idea when you cannot walk into the office and ask what is going on.

Where to start

If you are weighing up whether to hold on, list with an agent, or take a certain sale and be done with it, the first thing you need is an honest figure — not a portal estimate, and not what your cousin heard number 42 went for. Once you know the realistic range, the tax position and the timeline become straightforward arithmetic rather than a source of anxiety.

We are independent. We do not buy houses ourselves, which means we have no reason to talk you into a discounted sale if the open market is the better answer for you. If it would help to see what genuine cash buyers would pay for your property and compare that against a normal sale, you can compare offers and talk it through with us — no obligation, and no pressure to take a route that does not suit you.
