US Tax on UK Rental Income: A Guide for American Landlords

American citizens who own UK rental property must report the rental income twice — once on the UK Self Assessment and again on the US Form 1040 (Schedule E). The foreign tax credit generally prevents genuine double taxation, but differing rules on depreciation, mortgage interest and losses mean the two returns rarely produce the same profit figure.

Understanding US tax on UK rental income is essential for any American landlord in Britain. Your US filing obligation follows your citizenship, not your address, so being resident in the UK and already paying HMRC does not remove the requirement to file with the IRS. The good news is you should not pay full tax twice on the same profit — but only if both returns are prepared together.

Key takeaways

• A US citizen with a UK rental reports the income on both the UK Self Assessment and the US 1040 (Schedule E).
• The foreign tax credit (Form 1116) usually offsets US tax with the UK tax already paid on the same profit.
• The US requires depreciation of the building; the UK does not — so the taxable profit differs between the two systems.
• UK mortgage-interest relief is restricted to a basic-rate reduction, while the US generally allows full interest as a rental expense.
• Rent held in UK bank accounts can trigger FBAR and Form 8938 reporting once thresholds are crossed.

US tax on UK rental income: why the same rent is taxed twice

The UK taxes rental income arising from UK property because the property is located there — this is source-based taxation. The United States taxes its citizens and green-card holders on their worldwide income, wherever they live and wherever the income arises. A UK rental owned by an American therefore falls squarely inside both nets at the same time.

This is not a loophole or an error; it is how the two systems are built. The mechanism that stops you being fully taxed twice is relief for foreign taxes, primarily the foreign tax credit on the US side. You still file in both places — the relief simply prevents the combined bill from exceeding the higher of the two countries' liabilities on that income.

Our cross-border tax specialists prepare both returns as a single, coordinated exercise so the numbers reconcile and no relief is lost.

How do you report UK rental income to the IRS?

On the US return, UK rental activity is reported on Schedule E of Form 1040. You convert rents received and allowable expenses into US dollars, calculate the net profit or loss under US rules, and carry the result into your 1040. Because you have paid UK tax on the same property, you then claim the foreign tax credit on Form 1116 to offset the US tax attributable to that income.

The key point is that the US profit figure is calculated under US rules — not simply copied from your Self Assessment. Expenses, timing and, above all, depreciation are treated differently, so the Schedule E profit will usually differ from the HMRC figure. The IRS explains the worldwide-income principle in its guidance for US citizens and resident aliens abroad.

The depreciation mismatch: the US requires it, the UK does not

This is the single biggest structural difference. Under US rules, residential rental buildings must be depreciated — a portion of the building's cost is deducted each year over a fixed recovery period, reducing your US taxable profit. The UK gives no equivalent deduction for the building itself; relief for wear and tear comes only through narrower mechanisms such as capital allowances on qualifying items and replacement of domestic items relief.

The consequences are practical and long-lasting:

• Your US taxable profit is often lower than your UK profit, purely because of depreciation.
• Depreciation must be tracked from the first year the property is let, using the correct cost basis and land/building split.
• When you eventually sell, the US applies depreciation recapture, which affects the gain — a point covered in our companion guide on selling UK property as a US citizen.

Getting the depreciation schedule right from year one avoids painful corrections later, and it is not something to estimate.

Mortgage interest: Section 24 versus full US deductibility

Mortgage interest is treated very differently on each side. Since the UK's Section 24 reforms, finance costs on residential lettings are no longer a full deduction against rental profit for individuals; instead relief is given as a basic-rate tax reduction. Higher-rate UK landlords therefore feel the restriction most, and their UK taxable profit is higher than it would have been under the old rules. GOV.UK sets out the current position in its guidance on restricting finance-cost relief for residential landlords.

The US, by contrast, generally allows mortgage interest on rental property as an ordinary expense against rental income on Schedule E. So the same interest payment can reduce your US profit fully while only partially reducing your UK tax. This asymmetry is another reason the two profit figures diverge — and it can leave a residual US liability even after the foreign tax credit, because the US profit is lower and therefore carries less UK tax to credit against it.

Passive-loss limits and how losses are treated

Rental real estate is generally a passive activity for US tax, and passive losses can usually only offset passive income, with limited exceptions based on income level and participation. A UK rental that shows a US loss — common in early years because of depreciation — may not be immediately deductible against your other income, though disallowed losses are typically carried forward.

The UK also ring-fences rental losses, allowing them to be carried forward against future profits of the same UK property business. The result is that a loss can exist on both returns but be usable on neither straight away. Modelling this properly matters, especially across a portfolio; our cross-border calculator helps illustrate how the pieces interact before you file.

FBAR and Form 8938: when your rent sits in a UK account

Many American landlords collect rent into a UK current account, hold a deposit in a separate account, or run a letting through a UK agent's client account. Once your aggregate foreign account balances cross the relevant thresholds, two information reports can come into play:

• The FBAR (FinCEN Form 114), filed with the Treasury, reporting foreign financial accounts.
• Form 8938 (FATCA), filed with your 1040, reporting specified foreign financial assets.

Neither is an extra tax — they are disclosures — but the penalties for non-filing are serious, and rental cash flows are a common reason balances cross the line. If you have never filed these, review our guide to catching up on missed US tax returns and act before the IRS makes contact.

Practical steps for American landlords in Britain

Getting US tax on UK rental income right is mostly about discipline and record-keeping. To keep both returns clean and defensible:

1. Keep records in both currencies and use consistent exchange-rate conventions for rents and expenses.

2. Establish the US depreciation schedule in the first year of letting, with a proper land/building split.

3. Track UK Section 24 finance costs separately, since they are relieved differently on each side.

4. Reconcile the UK and US profit figures each year and document why they differ.

5. Check your FBAR and Form 8938 position annually as balances change.
