US Rental Property as a UK Resident: How Both Countries Tax the Income — and the Sale

A US rental property owned by a UK resident is taxed in both countries. The United States taxes the rental income — and, eventually, the sale — first, because the property sits on US soil; the United Kingdom then taxes the same income and gain as part of your worldwide position, giving credit for the US tax under the US-UK treaty. Done properly, you rarely pay full tax twice. But the two systems calculate the numbers differently — most sharply on depreciation — and the gaps between them are where the expensive surprises live.

This is the mirror image of the situation we cover in US tax on UK rental income for American landlords: same treaty, same credit machinery, opposite direction.

Key takeaways

• The US always taxes US-situs real estate first — the rent while you own it and the gain when you sell — regardless of where the owner lives or holds citizenship.
• UK residents are taxed on worldwide income, so the same rent and gain also belong on the Self Assessment return, with foreign tax credit relief preventing most double taxation.
• US depreciation is mandatory and has no direct UK equivalent, so the two countries' profit figures diverge every year — and the difference comes back as depreciation recapture on sale.
• The state where the property sits usually wants its own non-resident return on top of the federal one.
• Non-US sellers face FIRPTA withholding on the gross sale price; the UK computes its capital gains tax in sterling, so exchange-rate movements can create a UK gain that never existed in dollars.
• Holding the property through a US LLC can quietly break the credit machinery for a UK resident. Take advice before buying through one, not after.

The United States taxes the property first

Real estate is the clearest case of source-country taxation there is: the country where the land sits gets the first bite, and the US-UK treaty preserves that principle. Where the owner lives changes the paperwork, not the principle.

If you are a US citizen or green card holder living in the UK, nothing about the US side is new. You were already required to file a Form 1040 on worldwide income; the rental simply goes on Schedule E — rents in, deductible expenses out, depreciation claimed as US rules require. Our US-UK expat tax service handles this population daily.

If you are a UK resident with no US status — a British investor who bought a Florida condo or a Texas single-family home — the US still taxes the rent. The default treatment for a non-resident is blunt: tax withheld on the gross rents, with no deductions. Almost every non-resident landlord instead files Form 1040-NR and makes what is commonly called the net election, treating the rental as income effectively connected with a US business. That election moves you onto the same net-profit basis a US landlord enjoys: mortgage interest, management fees, repairs, insurance and depreciation all count. The election has formalities and, once made, persists — how and when to make it for your situation is a point to confirm with a professional rather than improvise.

Either way, a US federal return is part of owning this asset. It is not optional, and it does not replace anything on the UK side.

The UK taxes it again — as worldwide income

UK residents taxed on the arising basis pay UK tax on foreign property income as it arises, whether or not the money ever leaves the US. The rental goes on the foreign property pages of the Self Assessment return — computed under UK property-business rules, not copied across from the US return. Allowable expenses differ, the UK's restriction of relief for residential finance costs applies, and the UK has its own conventions for what is capital and what is revenue. The same year's rent can legitimately produce two different taxable profits, one per country.

Double taxation is then relieved by credit: because the treaty gives the US primary taxing rights over US real estate, the UK allows the US federal tax paid on the rental profit as a credit against the UK tax on that same income, capped at the UK tax attributable to it. Because UK taxable profit is usually higher than the US figure (depreciation, again), the credit typically covers the US layer and leaves a UK top-up to pay. The credit mechanics are unforgiving about matching income to tax — the same discipline we describe on the US side in our guide to foreign tax credit carryovers.

One carve-out: recent arrivals to the UK within the newer foreign income and gains regime may be temporarily outside UK tax on foreign income altogether for their early years of residence. The conditions are specific and the regime is new — confirm your position before relying on it.

Depreciation: the quiet mismatch at the centre of everything

If one concept explains most of the friction in US-UK property returns, it is depreciation.

US rules require residential landlords to depreciate the building (not the land) over a set recovery period, deducting a slice of its cost against rent every year. Critically, US law treats depreciation as allowed or allowable — your basis in the property is reduced by the depreciation you were entitled to claim even if you never claimed it. There is no opting out by ignorance.

The UK computation for a residential letting has no equivalent deduction for the cost of the building. So year after year:

• the US taxable profit runs lower than the UK profit on identical rent and expenses;
• the UK collects a top-up above the credited US tax; and
• an invisible US-side liability accrues, because every dollar of depreciation is coming back at sale.

When you sell, the US taxes the slice of gain attributable to accumulated depreciation under its own recapture rules, at rates set by US law, before the rest of the gain is dealt with. The UK, which never gave the deduction, simply taxes its own sterling gain and has no concept of recapture to match the US charge against. Aligning the credit across that mismatch — different amounts, different characterisations, often different tax years — is precisely the kind of work that should not be done for the first time in the week the return is due.

The state return most owners forget

The federal return is not the whole US story. The state where the property sits generally taxes the rental income and the eventual gain in its own right and expects a non-resident state return — and a state with no income tax at all changes that answer entirely, which is why the same investment can carry very different ongoing compliance depending on whether the condo is in Orlando or the duplex is in Cleveland. Two further wrinkles for UK owners: the US-UK treaty binds the federal government, not the states, and the basis on which HMRC will credit state income tax differs from the treaty mechanism for federal tax — confirm the treatment for your specific state before assuming full relief.

Selling as a non-US person: FIRPTA withholding

When a non-US person sells US real estate, FIRPTA — the Foreign Investment in Real Property Tax Act — obliges the buyer to withhold a percentage of the gross sale price and remit it to the IRS at closing. Three things matter in practice:

• It is withholding, not the tax. The seller files a US return for the year of sale computing the actual gain; excess withholding comes back as a refund.
• It is computed on gross proceeds, not gain. A property sold for only a modest profit can still suffer withholding many times the true liability, tying up cash for months.
• It can sometimes be reduced in advance. A withholding certificate application to the IRS, made before closing, can bring the withholding closer to the real liability — but it needs lead time, so raise it with your adviser when you list the property, not when you sign the contract.

US citizens and green card holders are outside FIRPTA — the buyer withholds nothing — but they report the gain on Form 1040 as usual.

The UK side of the sale: CGT in sterling

The UK taxes the same disposal under its capital gains tax rules — computed in sterling. Your acquisition cost is translated at the exchange rate when you bought; your proceeds at the rate when you sold. If the pound weakened across your ownership period, you can face a substantial UK gain on a property whose dollar value barely moved — the currency movement itself is taxable. The reverse can also soften a UK bill on a strong dollar-side gain.

Credit relief then has to be threaded through: the US, as the situs country, taxes the gain first; the UK credits the US federal tax against the UK CGT on the same gain, up to the UK tax due. Misaligned tax years (the UK's ends on 5 April), the recapture layer, and the sterling-versus-dollar computations mean the two returns must be prepared looking at each other, not in isolation. The same coordination problem in the opposite direction — with the added twist of US tax on currency gains on a UK mortgage — is covered in selling UK property as a US citizen.

A warning about LLCs

US attorneys and realtors reflexively recommend holding rental property in an LLC, and for a purely American owner that is usually unremarkable: the US ignores a single-member LLC and taxes the owner directly. For a UK resident it can be a trap. HMRC has generally taken the view that US LLCs are opaque — more like companies than partnerships — and the Anson decision, in which a taxpayer won credit relief on the facts of his particular LLC, did not change HMRC's general practice. The structural risk is that the US taxes you personally on the rental profits while the UK sees a company and income from it, and declines to credit the US tax against the UK liability — double taxation created purely by the wrapper. Whether any particular LLC is transparent or opaque for UK purposes is a facts-specific question ⚠ — if you already own US property through an LLC, or a US adviser is suggesting one, take cross-border advice before the next return is filed.

Getting the two returns to talk to each other

One property, two tax systems, two currencies, two year-ends. The returns that go wrong are almost always prepared separately — a US preparer who has never seen the Self Assessment, a UK accountant who has never met Schedule E. The records that make it work are mundane but essential: closing statements from purchase and sale, an accurate US depreciation schedule from year one, exchange rates for every relevant date, and a consistent story across both filings.
