Can I use the Streamlined Foreign Offshore Procedure if my only unreported income is UK rent?

Yes, provided you meet the eligibility conditions. The procedure is not limited to bank interest or investment income; any unreported foreign income, including rent from a UK buy-to-let, can be brought into compliance. You must meet the IRS non-residency test, have a valid Social Security Number, not be under IRS examination, and certify on Form 14653 that the failure was non-willful. The three returns must include all your worldwide income for those years, not just the rents, and six years of FBARs must be filed for your foreign accounts.

Does my UK rental property itself go on the FBAR or Form 8938?

No. The IRS comparison of Form 8938 and FBAR requirements confirms that foreign real estate held directly is not reportable on either form. What does get reported are the financial accounts connected to the property: the account that receives rent from your letting agent, any account used for repairs or service charges, and savings holding rental surpluses. If those accounts, together with your other UK accounts, exceed 10,000 dollars in aggregate at any time in the year, an FBAR is required. Holding the property through a company brings different reporting.

Do I have to claim depreciation on my UK buy-to-let for the missed years?

Depreciation reduces your basis whether or not you claimed it. IRS Publication 946 says basis is reduced by depreciation allowed or allowable, whichever is greater, so skipping it does not preserve basis for a later sale. The three streamlined returns should claim the correct ADS depreciation for those years, generally 30 years for foreign residential property placed in service after 2017. For earlier unfiled years, allowable depreciation still reduces basis, and Publication 946 identifies Form 3115 as the route for catching up unclaimed depreciation where appropriate.

Why is my US rental profit lower than the profit HMRC taxes?

Mainly because of mortgage interest and depreciation. Under HMRC's finance-cost restriction, known as Section 24, individual residential landlords cannot deduct mortgage interest from rental profit and instead receive a basic-rate tax reduction, currently 20 percent and rising to 22 percent from April 2027 outside Scotland. The US allows mortgage interest as a full Schedule E deduction and also requires depreciation of the building. The US profit is therefore usually lower, and UK tax paid on the higher UK profit often produces foreign tax credits that exceed the US tax on the rents.

Will I owe US tax on my UK rental income after the foreign tax credit?

Often little or none on the rents themselves, but it depends on the figures. UK income tax paid on the rental profit is claimed as a credit on Form 1116, generally in the passive category unless the high-taxed income or active rents rules apply. Because UK tax is usually charged on a higher profit than the US recognises, credits commonly cover the US tax on the rents, with excess credits carried back one year or forward ten years. Other income, such as US-source items or low-taxed investment income, can still leave a balance due.

Is there a penalty for filing under the Streamlined Foreign Offshore Procedure?

For taxpayers who qualify for the foreign version, the IRS does not impose the miscellaneous offshore penalty, and eligible filers are not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. You must still pay all US tax due on the three returns plus statutory interest. By contrast, the Streamlined Domestic Offshore Procedure charges a 5 percent penalty on the highest aggregate value of foreign financial assets, so confirming that you meet the 330-day, no-US-abode residency test is an important first step.

Streamlined Foreign Offshore for UK Buy-to-Let Income

The Streamlined Foreign Offshore Procedure is the IRS route that lets a US citizen or green-card holder living in the UK bring years of unreported UK buy-to-let income back into compliance without failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties, provided the failure was non-willful. In practice that means filing the three most recent years of delinquent or amended Form 1040s with a properly reconstructed Schedule E for each property, filing the six most recent years of FBARs, paying any US tax and interest due, and signing a non-willful certification on Form 14653.

For most London-based landlords the US tax bill turns out to be modest, because UK income tax on the same rents usually feeds a foreign tax credit. The real work is technical: US depreciation of foreign residential property, the gap between HMRC's Section 24 finance-cost restriction and the full US mortgage interest deduction, currency conversion, and the bank accounts that collect the rent.

What is the Streamlined Foreign Offshore Procedure?

The Streamlined Foreign Offshore Procedure (SFOP) is one of two streamlined filing compliance procedures published by the IRS for taxpayers whose failure to report foreign income, pay tax or file information returns was non-willful. The IRS defines non-willful conduct as conduct due to negligence, inadvertence or mistake, or conduct resulting from a good-faith misunderstanding of the requirements of the law.

According to the IRS page U.S. Taxpayers Residing Outside the United States, an eligible taxpayer must, for each of the most recent three years for which the US tax return due date has passed, file a delinquent or amended return with all required information returns, and must file delinquent FBARs for each of the most recent six years for which the FBAR due date has passed. Each return is marked Streamlined Foreign Offshore in red at the top, and full payment of tax and statutory interest accompanies the submission.

The headline benefit for a UK resident is that the foreign version carries no miscellaneous offshore penalty. The domestic version, the Streamlined Domestic Offshore Procedure, charges 5 percent of the highest aggregate balance or value of the taxpayer's foreign financial assets, so qualifying for the foreign route is valuable for anyone with significant sterling savings.

Do UK buy-to-let landlords qualify for Streamlined Foreign Offshore relief?

Most US persons who live and work in the UK will meet the residency test. For US citizens and green-card holders, the IRS requires that in at least one of the most recent three years for which the return due date has passed, the individual did not have a US abode and was physically outside the United States for at least 330 full days. Travel records should be checked rather than assumed, especially for bankers with frequent New York trips.

The other conditions matter just as much:

The failure to report the rental income, pay the tax and file FBARs must be non-willful, and you must be able to explain why in a signed narrative.
You must have a valid Taxpayer Identification Number, which for a US citizen or green-card holder means a Social Security Number.
You must not be under IRS civil examination or criminal investigation, even on an unrelated issue.
Every item of income must be reported for the three years, not just the rents: UK salary, bonus, dividends, interest and gains all belong on the returns.

The IRS also states that a streamlined submission does not produce a closing agreement. Returns remain open to examination, so rental schedules must be built properly, not estimated.

Why is UK rental income taxable in the US at all?

The United States taxes its citizens and green-card holders on worldwide income wherever they live. HMRC taxes rent from a Clapham or Manchester flat because the property is in the UK, and the IRS taxes the same income because the landlord is a US person. The US-UK treaty and the foreign tax credit prevent full double taxation, but neither removes the obligation to report. A sincere belief that paying HMRC was enough can be the kind of good-faith misunderstanding the non-willful standard contemplates.

How do you reconstruct Schedule E for a UK buy-to-let?

Schedule E (Form 1040) is the US schedule on which rental income and expenses are reported, and IRS Publication 527 makes no distinction between US and foreign property for this purpose. Each UK property is a separate line of Schedule E, with gross rents, deductible expenses and depreciation shown in US dollars for the US calendar year.

The reconstruction usually starts from UK records, which are organised around the UK tax year running from 6 April to 5 April. Because the US reports on a calendar year, monthly figures from letting-agent statements and bank statements have to be re-cut into January-to-December periods. Agent statements, completion statements, mortgage statements and service-charge demands are the core documents.

Expenses that are generally deductible on the US return for a let property include:

Letting-agent and management fees, including tenant-find fees and inventory costs.
Service charges and ground rent on leasehold flats, to the extent they relate to the letting period.
Repairs and maintenance that keep the property in ordinary working condition.
Landlord insurance, safety certificates, licensing fees and council tax during void periods where the landlord bears it.
Mortgage interest on borrowing used to acquire or improve the let property.
Legal and accounting fees relating to the letting activity.

Publication 527 draws a firm line between repairs and improvements. A repair or maintenance expense may generally be deducted, but an expense that results in a betterment to the property, restores it or adapts it to a new or different use must be capitalised and depreciated. Replacing a broken boiler part is a repair; a full kitchen refit or a loft conversion is an improvement. UK accounts do not always draw this line in the same place, so each significant spend should be reviewed against the US rules.

How is a UK rental property depreciated for US tax purposes?

Depreciation is the annual deduction for the cost of the building, excluding land, spread over its recovery period. Because a UK flat is property used predominantly outside the United States, it must be depreciated under the Alternative Depreciation System (ADS) rather than the 27.5-year schedule used for US residential rentals. Publication 527 states that under ADS residential rental property has a 30-year recovery period, and notes that the period was 40 years for property placed in service before 1 January 2018. The straight-line method and mid-month convention apply.

Missed depreciation cannot simply be ignored. Publication 946 explains that basis must be reduced by the depreciation allowed or allowable, whichever is greater. In other words, the IRS treats you as having taken the depreciation you were entitled to, even in years you never filed. That matters in two ways: the three streamlined returns should claim the correct depreciation for those years, and the property's adjusted basis must reflect the allowable depreciation for earlier years that fall outside the streamlined window. Publication 946 points to Form 3115, the application for change in accounting method, as the mechanism for catching up unclaimed depreciation where amended returns are not enough, and whether that is needed depends on the property's filing history.

The starting basis is the purchase price plus acquisition costs that must be capitalised, such as legal fees on the purchase, converted into dollars at the exchange rate when those amounts were paid. A reasonable land-to-building allocation is then applied, supported by a valuation or other evidence rather than a round-number guess.

Why do UK and US rental profits never match?

The biggest single difference is mortgage interest. Publication 527 confirms that mortgage interest on a rental property is deductible on the US return. HMRC takes a different approach for individual landlords of residential property: under the finance-cost restriction commonly called Section 24, mortgage interest is not deducted from rental profit. Instead, GOV.UK guidance explains that the landlord receives a tax reduction equal to the basic rate value, currently 20 percent, of the lowest of finance costs, property business profits and adjusted total income, with unrelieved amounts carried forward.

GOV.UK has also announced that from April 2027 separate property income rates will apply outside Scotland: a property basic rate of 22 percent, a property higher rate of 42 percent and a property additional rate of 47 percent, with finance-cost relief given at the 22 percent property basic rate. Returns covering US calendar years that straddle April 2027 will therefore need UK tax computed under both regimes.

Add US depreciation, which has no direct UK equivalent for residential buildings, and the result is predictable: the US Schedule E profit is usually lower than the UK taxable property profit, and for a heavily mortgaged higher-rate taxpayer the gap can be large. That divergence is not an error; it is the reason the foreign tax credit calculation has to be done carefully, and the reason excess credits often arise.

How does the foreign tax credit offset US tax on UK rents?

The foreign tax credit is a dollar-for-dollar credit against US tax for income tax paid to a foreign country, claimed on Form 1116. The IRS instructions for Form 1116 place rents in the passive category unless they are active business rents or qualify under the high-taxed income exception, where the foreign tax on the income exceeds the highest US tax that could be imposed on it. For a typical UK buy-to-let taxed at 40 or 45 percent in the UK, the high-taxed income rules often come into play, and the correct basket has to be determined year by year.

Two practical issues dominate. First, UK tax is computed for the April-to-April year and must be allocated to the US calendar year it relates to. Second, because Section 24 means UK tax is charged on a higher profit than the US recognises, the UK tax attributable to the rents can exceed the US tax on those rents. Unused credits can generally be carried back one year and forward ten years, which is why the three streamlined years should be prepared together rather than in isolation.

What exchange rate should you use?

The IRS states that it has no official exchange rate and that the general rule is to use the rate prevailing when an item is received, paid or accrued. It also publishes yearly average currency exchange rates that many taxpayers use for recurring items such as monthly rents and expenses. Whichever approach is chosen should be applied consistently across all three returns. Purchase price and improvements are converted at the rate on the date paid, and that dollar basis drives depreciation and eventual gain. A sterling mortgage can also create a separate US currency gain or loss when principal is repaid, which should be reviewed at the same time.

Which accounts go on the FBAR and Form 8938?

The FBAR, FinCEN Form 114, is filed electronically through FinCEN's BSA E-Filing System by US persons whose foreign financial accounts exceeded 10,000 dollars in aggregate at any time during the calendar year. It is due 15 April with an automatic extension to 15 October. For a landlord, the net is wider than the main current account: the account that receives rents from the letting agent, any separate account used for service charges or repairs, savings accounts holding rental surpluses, and accounts over which you have signature authority all need to be considered. Tenancy deposit money held in a landlord-controlled account should also be reviewed.

Form 8938 is a separate IRS disclosure of specified foreign financial assets filed with the tax return. The IRS comparison of Form 8938 and FBAR requirements confirms that foreign real estate held directly is not reportable on either form, so the flats themselves are not listed. The sterling bank accounts, ISAs and investment accounts may be. For taxpayers living abroad, Form 8938 applies when specified foreign financial assets exceed 200,000 dollars on the last day of the year or 300,000 dollars at any time for single filers, and 400,000 dollars or 600,000 dollars respectively for joint filers. If the property is held through a company rather than personally, entirely different information returns can apply.

What if the buy-to-let is owned jointly with a non-US spouse?

This is one of the most common gaps in streamlined filings for UK landlords, and competing guides rarely address it. On the UK side, GOV.UK explains that married couples and civil partners who live together are normally taxed on jointly owned property income on a 50:50 split, unless they make a Form 17 declaration of unequal beneficial interests backed by evidence. On the US side, the US spouse reports his or her own share of the rents, expenses and depreciation, typically on a married filing separately return.

The IRS allows a US citizen married to a nonresident alien to elect to treat the spouse as a US resident and file jointly, but the consequence is that both spouses must report their entire worldwide income for that year and later years, and neither can generally claim treaty benefits as a resident of another country while the election is in effect. For a British spouse with significant earnings or investments, that is rarely attractive, and making the election inside a streamlined submission should be a deliberate decision rather than a default.

Joint bank accounts carry their own FBAR point. FinCEN's instructions require each US owner of a jointly held account to report the entire value of the account, not just a half share. The non-US spouse has no FBAR filing obligation, but the US spouse's FBARs must show the full balance of any joint rent-collection account.

What happens when you later sell the property?

Selling a buy-to-let that was brought into compliance through the Streamlined Foreign Offshore Procedure is the second major gap angle, because the consequences of the depreciation you claimed, or should have claimed, arrive on sale. The US gain is measured in dollars: the dollar sale proceeds less the dollar adjusted basis, which is the historic dollar cost reduced by depreciation allowed or allowable. Currency movement alone can create a US gain even where the sterling gain is modest, or reduce it where sterling has weakened.

IRS Topic 409 explains that the portion of gain attributable to prior depreciation on real property, known as unrecaptured section 1250 gain, is taxed at a maximum rate of 25 percent, and that individuals with significant investment income may also face the net investment income tax. On the UK side, residential property gains are subject to UK capital gains tax and a separate UK reporting and payment timetable. The foreign tax credit can help align the two, but the different basis calculations mean the numbers must be modelled before exchange of contracts, not after completion.

Worked scenario: a London banker with two buy-to-lets

The figures below are purely illustrative and are used only to show the method. Consider a US citizen working at an investment bank in London who has lived in the UK throughout the relevant period, files UK Self Assessment, but has never filed a US return. She owns two flats: Flat A, bought in 2016, and Flat B, bought in 2019, both mortgaged and managed by a letting agent.

Step one is scope. Her streamlined submission covers the three most recent tax years whose due dates have passed and the six most recent FBAR years. Her travel diary confirms more than 330 full days outside the US and no US abode in at least one of those years, so the Streamlined Foreign Offshore Procedure is available. All of her income, including salary, bonus and deferred share awards, goes on the returns alongside the rents.

Step two is the Schedule E for each flat. Suppose Flat B collects rent of 30,000 pounds in a calendar year, with agent fees of 3,600 pounds, service charge and ground rent of 3,000 pounds, repairs of 1,400 pounds and mortgage interest of 9,000 pounds. Each figure is converted at a consistently applied rate. Depreciation is then computed: if the building element of Flat B, excluding land, was 360,000 pounds at purchase, converted at the 2019 purchase-date rate, the annual ADS deduction is that dollar amount divided by 30, with the mid-month convention applied in 2019. Flat A, placed in service before 2018, uses the recovery period applicable to its placed-in-service date, which Publication 527 notes was 40 years under ADS for property placed in service before 1 January 2018.

Step three is the UK comparison. HMRC's property profit for Flat B excludes the 9,000 pounds of interest and gives a basic-rate tax reduction instead, and has no deduction for depreciation of the building. The UK profit is therefore materially higher than the US Schedule E profit, and the UK tax paid on the rents, allocated from the April-to-April tax years to the calendar year, becomes the starting point for Form 1116.

Step four is the credit and the reporting. The UK tax is applied in the correct basket after considering the high-taxed income rules; excess credits are tracked for carryforward. The FBARs list the rent-collection account, the service-charge account, her salary account and her savings accounts, and Form 8938 lists specified financial assets above the threshold, but not the flats themselves. Her Form 14653 narrative explains her belief that paying HMRC discharged her obligations, how she learned otherwise, and the source of funds in her UK accounts.

How should the Form 14653 non-willful narrative read?

Form 14653 is the signed certification, under penalty of perjury, that the failures were non-willful. The form asks for specific reasons for the failure to report all income, pay all tax and file all required information returns, including FBARs, and it asks for the whole story, favourable and unfavourable, including personal and financial background and the source of funds in foreign accounts. A single generic sentence is a weakness, not a safeguard.

For a buy-to-let landlord, a credible narrative usually covers when the properties were bought and why, who prepared the UK returns and what the landlord was told, the belief that UK tax on the rents was the only tax due, when the US obligation came to light, and the steps taken immediately afterwards. It should be consistent with the documents in the file, because the returns remain open to examination.

What is no longer available, and what should you avoid?

The IRS withdrew its Delinquent FBAR Submission Procedures page around July 2026, so landlords who owe no additional tax should not plan around that route. For a UK buy-to-let owner who never filed US returns, the Streamlined Foreign Offshore Procedure remains the principal published pathway for non-willful cases. Filing only the current year and moving on leaves earlier years exposed.

A comprehensive US and UK tax preparation and compliance engagement for this situation brings together both sides of the ledger: the UK Self Assessment figures, the US Schedule E reconstruction with correct ADS depreciation, the Form 1116 computation across the UK and US tax years, six years of FBARs, Form 8938 where required, and a Form 14653 narrative grounded in the documents. Done properly, it resolves the past and leaves you with clean records for every future year and, eventually, for the sale.
