Offshore & Non-Resident Landlords
Living abroad, or money overseas HMRC doesn’t know about? This can be put right.
If you live abroad and rent out a UK property, or you have foreign income or assets you never declared, the UK tax rules can feel daunting from a distance. They needn’t. This page explains, in plain English, what you owe and how to put it right — wherever in the world you are.
Already had a letter from HMRC? Coming forward is still the strong move, but a letter changes the picture — understand exactly what yours means first. See what your letter means →
First: which situation are you in?
“Offshore” and “non-resident” cover a few quite different things, and each has its own route. Find yourself below — then you’ll know which part of this page (and which other pages) matter to you.
You live abroad and rent out a UK home
Undeclared rent from a UK residential property — even though you live overseas.
Route: the Let Property Campaign — it covers non-residents too.You have undeclared offshore income or assets
Foreign rent, foreign bank interest, overseas investments or assets HMRC doesn’t know about.
Route: the Worldwide Disclosure Facility — explained below.You’re selling (or sold) UK property
Non-residents must report every UK property sale — even at no gain — within 60 days.
Route: Property Disposals & Capital Gains Tax.Renting out a UK home while you live abroad
Here’s the thing many overseas landlords don’t realise: rent from a UK property is taxed in the UK, wherever you live. Paying tax in your country of residence doesn’t remove the UK bill, and neither does having a letting agent.
There’s a specific system for this, called the Non-Resident Landlord Scheme. In plain terms:
- Your letting agent (or your tenant, if they pay you more than £100 a week and there’s no agent) is supposed to hold back basic-rate tax from your rent and pay it to HMRC.
- Or, you can apply to HMRC (on a form called NRL1) to receive your rent in full, and settle the tax yourself through a tax return.
- Either way, you normally still file a UK Self Assessment return each year.
If none of that has been happening — no tax held back, no returns filed — then you have undeclared rental income to put right, and a disclosure is exactly how you do it. The good news: as a non-resident individual, your route is the same favourable one as UK-based landlords — the Let Property Campaign (it’s open to non-residents, though not to companies or trusts).
Undeclared offshore income or assets: the Worldwide Disclosure Facility
Maybe what you didn’t declare is offshore: foreign rental income, interest on an overseas bank account, gains on foreign investments, or assets held abroad. If so, there’s a dedicated HMRC route for it — the Worldwide Disclosure Facility (WDF).
It works much like the other disclosure routes:
- You notify HMRC (through their online Digital Disclosure Service) that you intend to disclose.
- You then have 90 days to work out the full position, submit it, and pay.
The WDF is the right home for anything with an offshore element — not the Let Property Campaign (which is for UK residential rent) or the general disclosure service. If you’re unsure, that’s exactly what the which-route questions help settle.
Why coming forward matters even more with offshore
This is the honest part, and it’s worth understanding calmly rather than fearing. Offshore matters are treated more seriously than UK-only ones, for two reasons:
- HMRC already gets the data. Under an international agreement called the Common Reporting Standard, over 100 countries and territories automatically send HMRC information about accounts and income held by UK taxpayers. A newer, matching framework does the same for crypto assets — data collection began in 2026, and using an offshore exchange doesn’t put it out of reach, because the information is sent back to HMRC. So offshore matters tend to surface — it’s often a question of when, not if.
- The penalties are far higher. This is the part most people don’t realise. For offshore matters, the penalty can be as much as the unpaid tax all over again — sometimes more, so tax, interest and penalty combined can end up larger than what you failed to declare.
- But the difference is in your hands. Coming forward voluntarily, before HMRC contacts you, reduces the penalty substantially. That difference is large, and entirely within your control.
So the calculus is simple and in your favour: the sooner you put an offshore matter right, the smaller and calmer it stays. Waiting is the one choice that reliably makes it worse. Because the stakes are higher here, this is the area where getting a professional alongside you most often pays for itself — but the first step, understanding where you stand, you can take today.
How to come out of this in the best position
With offshore matters the stakes are higher — which means the difference between doing this well and doing it badly is bigger than anywhere else. These are the legitimate things that protect you:
- Act before a nudge letter arrives — this is the big one. For an honest, careless error, disclosed voluntarily and reasonably promptly, the penalty can be as low as 0%–30% of the tax. That’s the best case, not a guarantee: less co-operative countries, older years, and deliberate behaviour all push it higher, and some older offshore matters carry a much steeper floor. But the moment HMRC sends you a nudge letter, you lose that low “unprompted” range — and it climbs. So coming forward first is, by a distance, the single biggest saving on this whole subject. It’s also exactly why a professional’s read on your own case pays for itself here.
- Already paid tax abroad? Don’t pay it twice. Was the same income taxed in the country it arose in? You can usually claim a Foreign Tax Credit: the foreign tax already paid is set against your UK bill under the double-tax treaty. This is one of the most valuable and most missed offshore reliefs.
- Claim every relief and allowance, year by year. Personal allowances, allowable costs on foreign rent, and the usual reliefs still apply to each year of the disclosure — they reduce the tax just as they would at home.
- Gaps in your records are expected. HMRC knows old offshore paperwork is hard to reconstruct; it expects reasonable efforts, not perfection. Don’t let missing statements stop you starting.
Doing it yourself: what the process actually looks like
For a straightforward offshore matter, you can prepare and even submit this yourself — here’s the real shape of it, so you know what you’re taking on:
- Confirm your residence position for each year. This is the foundation, because it decides what’s even taxable in the UK. HMRC’s free online Statutory Residence Test tool walks you through it year by year — a few plain questions about days spent in the UK and your ties here. Note any year where your status changed (a “split year”), because that changes the sums.
- List the income, year by year. For each tax year (6 April–5 April), write down the foreign rent, interest, dividends or gains. Use one line per source per year — a simple spreadsheet is perfect. This becomes your working paper and, later, the backbone of the disclosure.
- Convert to sterling correctly. HMRC accepts a consistent method — most people use HMRC’s own published monthly or yearly average exchange rates (free on GOV.UK). Pick one method and apply it to every year, so your figures are consistent and defensible. Keep a note of which rate you used.
- Find the foreign tax you already paid. Dig out the certificates or statements showing tax withheld or paid abroad on that income. This is what unlocks the Foreign Tax Credit — the single most valuable thing you can get right yourself, because it stops the same income being taxed twice.
- Work out the tax and interest. Apply the UK rates for each year to the converted income (less any allowable costs and reliefs), then subtract the Foreign Tax Credit. HMRC publishes the interest rates and there are free interest calculators online. This is arithmetic you can do — the free tools on this site are built to help.
- Self-assess your behaviour honestly. The disclosure asks you to say whether the error was an innocent mistake, careless, or deliberate. This is a real decision with real consequences — it sets both your penalty band and how many years you must go back. Answer it truthfully; if “deliberate” is even possibly the honest answer, stop and get specialist advice (that’s COP9 territory, not this).
- Notify, then submit and pay within 90 days. Notify HMRC through the Digital Disclosure Service, get your Disclosure Reference Number, and the 90-day clock starts. Submit the figures and pay — or arrange Time to Pay if you can’t settle in one go. You sign and submit: it’s always your disclosure.
An illustrative example
The expat who acted before the letter came
Take a landlord we’ll call Aisha (made up, to show how it works). She moved abroad years ago and kept renting out her old UK flat. She also had a savings account in her new country earning interest. None of it was declared to HMRC — she assumed paying local tax was enough.
Reading about the Common Reporting Standard, she realised HMRC would likely get the data anyway — so she moved first. She gathered her statements, found proof of the tax she’d already paid abroad on the interest, and made a full, unprompted disclosure through the Worldwide Disclosure Facility.
The outcome, with rough numbers to show the shape of it. Say Aisha’s UK flat made about £6,000 profit a year, and the overseas savings earned about £1,000 a year in interest — over six undeclared years. Here’s roughly how it played out:
| Item | Roughly |
|---|---|
| UK tax on the rental profit (6 yrs) | £7,200 |
| UK tax on the overseas interest | £1,200 |
| − Foreign Tax Credit (tax already paid abroad) | − £600 |
| Tax to pay | £7,800 |
| Penalty — because she came forward unprompted (low) | £780 |
| Aisha’s total | £8,580 |
| Had she waited for HMRC’s letter, the penalty alone could have been | £3,500+ |
So two choices put real money back in her pocket: the Foreign Tax Credit stopped her being taxed twice (about £600), and coming forward first kept the penalty low instead of several times higher — a difference here of roughly £2,700. She settled calmly, on time, and swapped years of low-level worry for a clean record.
Illustrative only — the person and every figure here are hypothetical and rounded, just to show how the choices play out. Real penalties depend on the country, the years, and your behaviour, and can be higher or lower; your own position should be worked out and confirmed with a professional.
In plain English: a quick jargon-buster
New to all this? Here’s what the key terms mean, in the plainest words.
- “Non-resident”
- HMRC’s term for someone who counts as living outside the UK for tax purposes. It isn’t simply about six months away — HMRC uses a day-counting Statutory Residence Test (free to check on GOV.UK) that also weighs your ties to the UK. Importantly, you can be non-resident and still owe UK tax on UK income, such as rent from a UK property.
- “Offshore”
- Anything outside the UK — foreign income, an overseas bank account, investments or assets held abroad. Offshore tax matters are treated more strictly than UK-only ones.
- “Non-Resident Landlord Scheme” (NRLS)
- The system for taxing a non-resident’s UK rental income. Your agent or tenant normally holds back basic-rate tax, unless HMRC has approved you (via form NRL1) to receive the rent in full.
- “Worldwide Disclosure Facility” (WDF)
- HMRC’s route for putting right undeclared tax that has an offshore element. You notify, then have 90 days to disclose and pay.
- “Common Reporting Standard” (CRS)
- An international agreement between over 100 countries and territories. They automatically share details of each other’s bank accounts with the local tax authority. It’s how HMRC finds out about many offshore accounts.
- “A disclosure”
- Telling HMRC about tax you didn’t report before, and paying what’s owed. That’s all it is: putting the record straight.
