US UK Tax Landlords Guide: One Let Flat, Two Returns, One Ledger
One UK flat, one year of rent, two tax returns that never show the same profit. Here is a side-by-side ledger of the same figures on the UK property pages and on Schedule E, with a worked example in pounds and dollars.
Every set of keys handed over starts one rent figure that has to be reported twice, on the UK return and on Schedule E.

US UK tax landlords: an introduction
US UK tax landlords report the same rent to HMRC and to the IRS, yet the two returns almost never show the same profit. The UK restricts mortgage interest relief and gives nothing for the building's wear. In contrast, the US deducts the interest in full and requires depreciation. Currency and calendar differences then widen the gap. The way to keep control is one ledger that feeds both returns.
This article supports our guide to preparing US and UK tax returns together. It follows one let flat through a single year, line by line, on each return. Then it shows why the foreign tax credit usually leaves no US tax on the rent, and what reporting sits around it.
Who counts among US UK tax landlords
In this guide, US UK tax landlords are US citizens or green card holders who let property in the UK. A US person is someone the US taxes on worldwide income wherever they live. Most live in the UK, so both countries tax the rent in full. Some live in the US and let a former home. We cover that group briefly near the end.
Why one ledger matters
A rental ledger is a dated record of every pound of rent and every cost, kept once. From it, you build two computations. The UK one runs from 6 April to 5 April in pounds. The US one runs from 1 January to 31 December in dollars. Therefore, each figure needs a date, an amount and a note of how each country treats it.
How does HMRC tax rent from a UK let?
HMRC taxes your rental profit after allowable running costs, but it does not deduct mortgage interest. Instead, it gives a tax reduction worth 20% of the interest. It also gives no deduction for the building itself.
What the UK property pages let you deduct
GOV.UK's guide to working out your rental income lists the costs you can take off rent. Agent fees, insurance, service charges, repairs and accountancy usually qualify. Capital improvements do not. Furthermore, there is no box for wear on the building, so a flat bought for £240,000 produces no annual allowance on the UK return.
The finance cost restriction
The finance cost restriction is the UK rule that replaced the interest deduction on residential lets. HMRC's case studies on the restriction explain the reduction. It is 20% of the lowest of three figures: finance costs, property profits, or adjusted total income above the personal allowance. Unused finance costs carry forward. However, the reduction cannot create a refund.
Replacement of domestic items and the property allowance
Replacement of domestic items relief is a deduction for replacing furniture, furnishings and appliances in a let home. It does not cover the first purchase, and an upgrade only qualifies up to the cost of a like-for-like item. Separately, the property allowance gives up to £1,000 of rent tax-free. If you claim it, you cannot also deduct your expenses. For most US UK tax landlords with a mortgage, actual expenses are larger, so the allowance rarely helps.
Rates from April 2027
Property income will soon have its own UK rates. The Budget on 29 October 2026 proposed property rates of 24%, 44% and 49% from 6 April 2027 for England, Wales and Northern Ireland, as the GOV.UK policy paper on property and savings rates sets out. Legislation is expected in Finance Bill 2026-27. Consequently, more UK tax will sit against your rent, and more foreign tax credit may go unused.
How does the IRS tax the same rent on Schedule E?
The IRS taxes the net rent on Schedule E, after deducting mortgage interest in full and a compulsory depreciation charge. That usually makes the US profit far smaller than the UK one.
Mortgage interest in full
IRS Publication 527 states plainly that you can deduct mortgage interest on a rental property. There is no basic-rate cap. So the £7,200 of interest that earns only a 20% reduction in the UK comes straight off the US profit. Agent fees, insurance and repairs come off on both returns.
Depreciation over 30 years
Depreciation is the annual deduction for the cost of a building as it wears out. For a UK flat, section 168(g) of the Internal Revenue Code requires the alternative depreciation system for property used mainly outside the US. IRS Publication 946 gives 30 years for residential rental property placed in service after 2017. Land is never depreciated, so you first split the price between land and building. Notably, the IRS treats depreciation as reducing your cost whether or not you claim it, which matters when you sell.
When the US result is a loss
Interest plus depreciation can push the US figure below zero. Rental income is passive, and passive losses generally offset only passive income. Publication 527 describes a special allowance of up to $25,000 for owners who actively participate. It shrinks once modified adjusted gross income passes $100,000 and disappears at $150,000. Form 8582 tracks any loss you cannot use yet.
Why do the UK and US rental profits differ?
For US UK tax landlords, they differ because each country treats interest, depreciation, replacements and timing in its own way. A worked example shows the scale.
Consider a typical case
Consider a typical case. Rachel, a fictional US citizen living in Bristol, earns a salary of £30,000. She also lets one flat bought in July 2019 for £240,000. Her records split £200,000 to the building. We assume the pound bought $1.28 on purchase day, giving a US building cost of $256,000. Her rent is £1,500 a month, and her costs are steady through the year. In February 2026 she replaced a worn sofa for £800.
The UK ledger for 2025 to 2026
For the UK year to 5 April 2026, Rachel's rent is £18,000. She deducts agent fees of £2,160, other running costs of £1,840 and the £800 sofa under replacement relief. Her UK property profit is £13,200. Using 2025 to 2026 rates from GOV.UK's previous tax years table, it is all taxed at 20%, which is £2,640. Next, the finance cost reduction is 20% of her £7,200 interest, the lowest of the three figures. That is £1,440, leaving UK tax of £1,200 on the rent.
The US ledger for calendar 2025
For the US year to 31 December 2025, the rent and running costs are the same, because they were steady. By contrast, the sofa falls in 2026, so it is absent. We convert at the IRS 2025 average of 0.759 pounds per dollar. Rent becomes $23,715. Agent fees are $2,846, other costs $2,424 and interest $9,486. Depreciation is $256,000 over 30 years, or $8,533. Her US rental profit is just $426.
How the credit works on these figures
The UK taxes about £13,200 of profit. Meanwhile, the US taxes $426, roughly £323. Suppose Rachel's US marginal rate is 12%; the US tax on the rent is about $51. Her UK tax of £1,200 is around $1,581 at the same rate, so the credit removes the $51 entirely. Moreover, the UK tax exceeds the top US rate on the US-measured income. Under the Form 1116 instructions, that makes it high-taxed income, which moves out of the passive category. The unused credit then follows the carryback and carryforward rules.
Which exchange rate and which year should you use?
You may use spot rates or a consistent posted rate such as the IRS yearly average. As for the year, the US return always follows the calendar year, whatever the UK tax year says.
Spot rates or the yearly average
The IRS page of yearly average currency exchange rates says the IRS has no official rate. It states the general rule is the spot rate when you receive or pay an item. It also accepts any posted rate used consistently. For US UK tax landlords with steady monthly rent, the average is a practical choice. However, a large one-off cost, such as a new roof, is better converted on its own date. Whichever method you pick, record it and keep it.
Matching 6 April to 1 January
The UK tax year runs from 6 April to 5 April. The US year runs from 1 January to 31 December. So each US return draws on parts of two UK years. In practice, you total your ledger by month and cut it twice. Rachel's sofa shows why: it sits in the UK 2025 to 2026 year but the US 2026 year. On the US side, furniture is also a capital item with its own depreciation, not a one-off deduction.
When UK tax counts for the credit
IRS Publication 514 explains two methods. On the cash method, you claim UK tax in the year you pay it. On the accrual method, UK tax accrues on the last day of the UK tax year. Rachel's 2025 to 2026 UK tax would then belong to her US 2026 return. Once made, the accrual choice binds later years. Unused credits go back one year and forward ten.
What reporting comes with a UK let beyond the two returns?
Expect US account reporting for the rent account and, for many landlords, UK digital reporting. If you live in the US, the UK also collects tax on rent at source.
FBAR and Form 8938 for the rent account
The flat itself is not reported. The IRS comparison of Form 8938 and FBAR lists directly held foreign real estate as reportable on neither. However, the UK bank account where US UK tax landlords receive rent is a foreign financial account. Under FinCEN's FBAR rules, you file if your foreign accounts together exceed $10,000 at any time in the calendar year. For Form 8938, taxpayers living abroad file above $200,000 at year end or $300,000 at any time, if single. Our article on FBAR and Form 8938 sets out the overlap.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax is HMRC's system of quarterly digital updates for landlords and the self-employed. GOV.UK's start-date guidance sets the test. Qualifying income over £50,000 in 2024 to 2025 meant starting from 6 April 2026. The threshold is £30,000 for 2025 to 2026, starting April 2027, and £20,000 for 2026 to 2027, starting April 2028. Qualifying income is turnover before expenses, as GOV.UK's qualifying income guide confirms. Salary does not count. Rachel's £18,000 of rent is below all three thresholds, for now. Many US UK tax landlords with one flat sit below these lines today.
Quarterly updates and the US year
Under HMRC's quarterly update rules, updates are due on 7 August, 7 November, 7 February and 7 May. Helpfully, a quarterly ledger also makes the US cut easier. The quarter to 5 January lands close to the US year end, so you can total the remaining days by hand.
If you live in the US: the Non-Resident Landlord Scheme
If you live abroad for more than six months a year, the Non-Resident Landlord Scheme applies. Your letting agent deducts basic-rate tax from net rent unless HMRC approves gross payment. You still file a UK return, and the tax deducted counts towards it. For Making Tax Digital, non-residents count only UK property and UK self-employment income.
What should US UK tax landlords check each year?
Check five things in order: the ledger, the UK computation, the US computation, the credit and the account reports. Taking them in sequence stops errors spreading from one return to the other.
Step one: close the ledger by month
First, total rent and costs for each calendar month. Mark each cost as revenue, replacement or capital. This single habit lets you cut the year at 5 April and at 31 December without reworking anything.
Step two: build the UK return
Next, total April to March for the UK property pages. Keep interest out of expenses and enter it as finance costs. Then file online by 31 January after the tax year ends, as GOV.UK's Self Assessment deadlines page confirms. Our UK Self Assessment service prepares these pages.
Step three: build Schedule E
After that, total January to December, convert at your chosen rate and add depreciation from your fixed-asset record. Many US UK tax landlords forget depreciation in early years; the cost of that omission only shows on sale. If earlier years were missed, a separate fix applies, which is beyond this article.
Step four: match the credit and the reports
Finally, match the UK tax to the correct US year under your chosen method. Check whether the high-taxed rule moves the rent into the general category. Then file the FBAR and, if needed, Form 8938. Our article on Form 1116 and UK tax explains the credit form in more depth.
How US UK Tax Experts can help
US UK Tax Experts prepares the US and UK returns from one file, so the two agree. For US UK tax landlords, we keep the monthly ledger, build the UK property pages and Schedule E from it, and work out the depreciation record and the credit. When you sell, our property gains service uses the same file. See also our article on a US person selling UK property.
Conclusion
One flat gives two profits, and both are right. The UK caps interest relief and ignores the building's wear. The US deducts interest in full and requires 30-year depreciation. As a result, the UK figure is usually higher, and the US credit usually covers the US tax. US UK tax landlords who keep one dated ledger can produce both returns, and defend both, without guesswork.

Frequently asked questions
Yes. US citizens and green card holders report worldwide income, so UK rent goes on Schedule E in dollars. You can usually claim a foreign tax credit for the UK tax paid on that rent.
Yes. The IRS lets you deduct mortgage interest on a rental property in full. This is a key difference for US UK tax landlords, because the UK gives only a 20% tax reduction for the same interest.
Yes. A UK rental is depreciated over 30 years under the alternative depreciation system if placed in service after 2017. The IRS reduces your cost by allowable depreciation even if you never claim it.
Usually because the US deducts mortgage interest in full and adds depreciation, while the UK does neither. Currency rates and the different tax years also move the figures apart.
Usually not. The UK taxes the rent first, and the US gives a foreign tax credit for that UK tax. Most US UK tax landlords find the credit covers the US tax on the rent, with unused credit carried to other years.
Yes, if your qualifying income passes the threshold, whatever your nationality. From 6 April 2026 it applies above £50,000, falling to £30,000 from April 2027 and £20,000 from April 2028. Qualifying income is turnover before expenses.
Yes, if all your foreign accounts together exceed $10,000 at any time in the year. The flat itself is not reported, but the account that receives the rent is.
