Is there a penalty under Streamlined Foreign Offshore for unreported UK commercial rent?

No. A taxpayer who meets the non-residency requirement and truthfully certifies non-wilful conduct on Form 14653 pays the tax due on the three returns plus statutory interest, with no streamlined penalty. The 5% miscellaneous offshore penalty belongs to the Streamlined Domestic Offshore Procedures, which apply to taxpayers who do not meet the non-residency test.

Over how many years is a UK office or warehouse depreciated on a US return?

IRS Publication 946 requires property used predominantly outside the United States to use the Alternative Depreciation System with the straight line method, and gives an ADS recovery period of 40 years for nonresidential real property. Land is excluded, the mid-month convention applies, and the dollar basis is fixed at the exchange rate on the purchase date.

Do I have to reduce my basis for depreciation I never claimed?

Yes. Publication 946 says basis is reduced by depreciation allowed or allowable, whichever is greater, and that unclaimed depreciation still reduces basis by the full amount allowable. For a long-held building this means years outside the three-year streamlined window reduce basis without any deduction, unless a correction such as a Form 3115 method change is available on the facts.

Does a tenant's rent deposit account count for the FBAR?

Generally yes where the account is in the landlord's name. FinCEN's FBAR instructions treat a US person as having a financial interest in an account of which they are owner of record or holder of legal title, regardless of whether it is maintained for their own benefit or another person's. The balance counts towards the $10,000 aggregate threshold.

Why is my UK property profit different from my US Schedule E profit?

The two systems relieve capital cost differently. The UK return gives no general depreciation on the building; relief comes through capital allowances such as the structures and buildings allowance at 3% a year for qualifying construction contracted on or after 29 October 2018. The US return claims 40-year ADS depreciation, uses the calendar year and translates everything into dollars.

Does opting to tax a UK commercial property for VAT change my US return?

It changes the bookkeeping, not the US rules. HMRC's VAT Notice 742A explains that lettings of land and buildings are normally exempt and that an option to tax makes supplies of that interest normally standard-rated. VAT collected from tenants and paid to HMRC must be separated from rent so that Schedule E income and expenses are not overstated.

Streamlined Foreign Offshore: UK Commercial Property Rent

The Streamlined Foreign Offshore route, formally the IRS Streamlined Foreign Offshore Procedure (SFOP), lets a US citizen or green card holder living in the UK bring unreported rent from personally owned UK commercial property onto US returns without a penalty, provided the omission was non-wilful. The submission is three years of delinquent or amended federal returns, six years of FBARs, a signed Form 14653 certification, and full payment of the tax and statutory interest shown on those returns.

That is the short answer. The longer one is that an office floor, a parade of retail units, a warehouse or a mixed-use block does not behave like a buy-to-let flat on a US return. The depreciation period is different, the bank accounts behind a commercial lease are different, the UK return claims allowances the US return does not recognise, and VAT may be running through the rent account. In the catch-up files we prepare, those are the points most often missed.

What is the Streamlined Foreign Offshore procedure and who can use it?

The Streamlined Foreign Offshore Procedures are an IRS compliance route for US taxpayers residing outside the United States who failed to report foreign income, and may have failed to file FBARs, because of non-wilful conduct. The IRS sets out the terms at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states. Non-wilful conduct is conduct due to negligence, inadvertence or mistake, or a good-faith misunderstanding of what the law requires.

For a US citizen or lawful permanent resident, the non-residency requirement is met if, in any one or more of the most recent three years for which the US return due date (or properly extended 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. A London-based investor who spends several weeks a year in New York for work needs the day count checked year by year before anything else is prepared, because failing the test moves the case to the Streamlined Domestic Offshore Procedures, which carry a 5% miscellaneous offshore penalty. The foreign procedures carry no penalty.

One point of wording deserves care. The IRS page describes the eligible taxpayer as someone who has failed to report the income from a foreign financial asset and pay tax as required by US law. A building held in your own name is not itself a financial asset, so the Form 14653 narrative should cover the whole picture: the rents, the interest on the rent and deposit accounts, and the accounts themselves. A non-compliant commercial landlord almost always has unreported UK accounts and missing FBARs as well. The taxpayer must also have a valid taxpayer identification number and must not be under IRS civil examination or criminal investigation.

What has to be filed under Streamlined Foreign Offshore for commercial rents?

Delinquent or amended Forms 1040 for each of the most recent three years for which the due date, or properly extended due date, has passed, with every required information return attached.
Schedule E for each property, with Form 4562 depreciation where required, Form 1116 for the UK tax, Form 8938 where the thresholds are met, and Form 8960 where Net Investment Income Tax applies.
FBARs for each of the most recent six years for which the FBAR due date has passed, filed electronically through FinCEN's BSA E-Filing System.
Form 14653, Certification by U.S. Person Residing Outside of the U.S., signed in original, with a copy attached to each return and information return.
Payment of all tax shown as due on the three returns and all applicable statutory interest on each late payment.
The words Streamlined Foreign Offshore written in red at the top of the first page of each return and information return.

The tax returns and certification go in paper form to the IRS address given on the page above; the IRS states that electronic submissions of this package will not be accepted. The FBARs go separately and electronically. We prepare the six FBAR years first, because the account list they produce is the best check that every rent, deposit and service-charge account has been found. Losses, where they arise on Schedule E, are subject to the passive activity rules and Form 8582.

The Form 14653 narrative is where commercial landlords are most exposed. A bare statement that the taxpayer did not know about US filing obligations is weak when the same person runs a seven-figure portfolio and files detailed UK returns every year. The facts that carry weight are specific: who prepared the UK returns, whether any US return was filed, when the problem was identified and what was done next. We draft from documents, not memory.

How does UK commercial rent go on Schedule E?

Rent from commercial property you own personally is reported on Schedule E, Part I, one column per property. The instructions at https://www.irs.gov/instructions/i1040se direct that where the property is in a foreign country you enter the city, province or state, country and postal code, and select the property type code from the list on the form. A mixed-use building with shops below and flats above is a single property for this purpose, but its depreciation classification needs separate thought, covered below.

Commercial leases produce receipts and outgoings that residential lets do not, and each needs a US answer:

Base rent, usually invoiced quarterly in advance, reported by a cash-basis individual when received rather than when the quarter falls.
Service charges recovered from tenants and the matching costs of running the building, which need consistent treatment so that the US return shows neither inflated income nor missing expenses.
Lease premiums and payments received for surrendering or varying a lease, which are not simply extra rent and need analysis before they are entered.
Loan interest, agent's fees, legal and surveyor's costs, business rates borne during void periods, and repairs, as distinct from improvements that must be capitalised and depreciated.

What depreciation period applies to UK commercial property on a US return?

Foreign commercial buildings are depreciated under the Alternative Depreciation System. IRS Publication 946, at https://www.irs.gov/publications/p946, lists property used predominantly outside the United States among the property that must use ADS with the straight line method, and its table of ADS recovery periods gives 40 years for nonresidential real property. Residential rental property has a different, shorter ADS period, which is why a residential schedule cannot simply be copied across for an office or warehouse.

Four practical rules follow. Land is never depreciable, so the purchase price has to be split between land and building on a supportable basis, such as a valuation or the contract allocation. Real property uses the mid-month convention, so the first and last years are part-years. Property required to use ADS cannot take the special (bonus) depreciation allowance. And improvements, such as a new roof or a landlord's fit-out, are treated as separate depreciable property with their own start date.

Mixed-use buildings need a classification step first. Whether a building is residential rental property or nonresidential real property for US purposes turns on how much of its gross rental income comes from dwelling units, under the rules in Publication 946. We make that determination on the rent roll and document it.

The dollar basis is fixed at acquisition. The sterling cost of the building is translated at the exchange rate on the purchase date and depreciated in dollars from there; it is not retranslated each year. For a property bought fifteen years ago that means finding the completion statement, not estimating.

What is the allowed or allowable depreciation trap when catching up?

This is the gap most guides to catching up leave out. Publication 946 states that you must reduce the basis of property by the depreciation allowed or allowable, whichever is greater. Depreciation allowed is what you actually deducted. Depreciation allowable is what you were entitled to deduct. If you do not claim depreciation you were entitled to, the publication is explicit that you must still reduce the basis by the full amount allowable.

Apply that to a landlord who has owned a warehouse for twelve years and reported none of it. The streamlined submission covers three years, and depreciation for those three years is claimed on the three Schedule E columns. The earlier nine years are outside the package. No deduction was ever taken for them, yet the basis of the building is reduced by nine years of allowable depreciation all the same. On a later sale, the gain is computed against that reduced basis, and the depreciation element of the gain is taxed as unrecaptured section 1250 gain at a maximum 25% rate according to IRS Tax Topic 409 at https://www.irs.gov/taxtopics/tc409. The owner pays tax on recapture of deductions that never reduced a dollar of tax.

Publication 946 describes two ways to correct depreciation: an amended return, available only in limited situations and within set time limits, and a change in accounting method requested on Form 3115. It also explains that a depreciation method is generally adopted by using a permissible method on the first return, or the same impermissible method on two or more consecutively filed returns. Whether Form 3115 is available therefore depends on the filing history: a taxpayer who filed US returns for years but left the property off is in a different position from one who never filed. We make that determination before the three returns are finalised, not at sale.

The practical consequence for the streamlined returns themselves is that the depreciation schedule must be built from the original placed-in-service date, with accumulated allowable depreciation carried forward into the first catch-up year. Starting the 40-year clock in the first year of the submission, as though the building had just been acquired, overstates the remaining basis and is wrong.

How are sterling rents and UK tax translated into dollars?

A US individual whose functional currency is the dollar must translate every item of income and expense received or paid in a foreign currency. The IRS guidance at https://www.irs.gov/individuals/international-taxpayers/foreign-currency-and-currency-exchange-rates says to use the exchange rate prevailing when the item is received, paid or accrued, and links to yearly average rates, which are commonly used for items arising evenly through a year. Quarterly rent and regular outgoings usually suit an average rate; a large one-off item such as a lease premium or a roof replacement is better translated at the rate on its own date. Whatever approach is chosen has to be applied consistently across all three returns.

UK tax is translated under its own rule. The Form 1116 instructions say a cash-basis taxpayer uses the rate of exchange in effect on the day the foreign tax was paid, while an accrual-basis claimant generally uses the average rate for the tax year to which the tax relates. There is also a calendar mismatch: the UK tax year runs from 6 April to 5 April, the US return follows the calendar year, and rents and expenses have to be re-cut from the underlying ledgers or agent statements.

How does the foreign tax credit work for UK tax on commercial rents?

UK income tax paid on the rents is claimed as a foreign tax credit on Form 1116. The instructions at https://www.irs.gov/instructions/i1116 require a separate Form 1116 for each category of income and state that passive category income generally includes rents, with an exception for active business rents. They also exclude high-taxed income from the passive category, meaning income on which the foreign tax, after allocation of expenses, exceeds the highest US tax that can be imposed on it. For a higher-rate or additional-rate UK taxpayer that test has to be run, not assumed.

Two features make the credit less tidy than owners expect. First, the US and UK compute different profits from the same building, so the UK tax is being matched against a different US income figure, often a smaller one because of depreciation. That commonly leaves excess credits, which may be carried to other years only within the limits in the Form 1116 instructions and only within the same category. Second, the 3.8% Net Investment Income Tax described at https://www.irs.gov/individuals/net-investment-income-tax counts rental income as net investment income, and the Schedule E instructions point to Form 8960 for rental and other passive activities. That tax is computed separately on Form 8960, not on Form 1116, so a streamlined return can show a balance due even where UK tax comfortably exceeds US regular tax on the rents.

Do rent deposit and service-charge accounts go on the FBAR and Form 8938?

Usually yes, and this is the second gap competitors miss. A US person must file an FBAR if the aggregate value of foreign financial accounts in which they have a financial interest, or over which they have signature authority, exceeds $10,000 at any time in the calendar year, as FinCEN states at https://www.fincen.gov/report-foreign-bank-and-financial-accounts. FinCEN's FBAR filing instructions define financial interest to include any account of which the US person is the owner of record or holder of legal title, regardless of whether the account is maintained for the benefit of the US person or for the benefit of another person.

That wording reaches straight into commercial property management. A rent deposit taken under a rent deposit deed is typically placed in a separate designated account in the landlord's name. The money is the tenant's security, but the landlord is the owner of record. A service-charge account holding tenants' contributions towards running the building, or a reserve fund for future major works, is in the same position when it stands in the landlord's name. Each is a foreign financial account of the landlord for FBAR purposes, and each counts towards the $10,000 aggregate.

The accounts we check for in every commercial file are:

The rent collection account and any personal current account into which rent is swept.
Each rent deposit account, one per tenant where they are held separately.
Service-charge accounts and reserve or sinking fund accounts held in the landlord's name.
Accounts held by a managing agent on the landlord's behalf, where the financial interest definition covering an agent or nominee acting for the US person has to be considered on the facts.
Any account over which the landlord has signature authority, for example an account of a tenants' management company on which they sign.

The FBAR instructions require the maximum value of each account during the year, converted at the Treasury's year-end reporting rate. The FBAR itself is due on 15 April following the calendar year, with an automatic extension to 15 October, as the IRS confirms at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar. Late FBARs within a streamlined submission are filed through the BSA E-Filing System with the streamlined reason selected and explained.

Form 8938 is separate. Under the instructions at https://www.irs.gov/instructions/i8938, a taxpayer living abroad must file if specified foreign financial assets exceed $200,000 on the last day of the tax year or $300,000 at any time during it, or $400,000 and $600,000 respectively for a married couple filing jointly. The building, held directly, is not a specified foreign financial asset. The accounts at UK banks are. A landlord with large deposit and reserve balances can therefore cross the Form 8938 threshold on accounts alone, and the form carries a $10,000 penalty for failure to file outside the streamlined terms. Property held through a company is a different regime entirely, with Form 5471 in play, and is outside this article.

How does the UK side differ from the US computation?

On the UK side the rents are returned on the UK property pages, SA105, of the Self Assessment return; HMRC's page at https://www.gov.uk/government/publications/self-assessment-uk-property-sa105 confirms these pages are used to record UK property income on the SA100. The UK computation gives no general deduction for depreciation of the building. Relief for capital spending comes through capital allowances instead, and that is where the two returns diverge.

The main allowance for the fabric of a commercial building is the structures and buildings allowance. HMRC's guidance at https://www.gov.uk/guidance/claiming-capital-allowances-for-structures-and-buildings sets the rate at 3% a year, claimed over 33 and one third years, and restricts it to construction where all contracts were signed on or after 29 October 2018. Land does not qualify and nor does residential use. Many owners of older commercial buildings therefore have no UK allowance on the structure at all, while the US return claims 40-year depreciation on the same building. Fixtures and plant within the building may qualify for separate plant and machinery allowances on the UK return, often at a much faster pace than any US deduction for the same items.

VAT is the other commercial-only feature. HMRC's VAT Notice 742A at https://www.gov.uk/guidance/opting-to-tax-land-and-buildings-notice-742a explains that supplies of land and buildings such as leasing or renting are normally exempt from VAT, and that an owner may opt to tax, after which supplies of that interest are normally standard-rated and VAT on related costs generally becomes recoverable. The option must be notified to HMRC and is long-lasting; the notice says it cannot normally be revoked for at least 20 years, and it does not apply to dwellings. For the US return the point is bookkeeping: where an option to tax is in place, the rent account will contain VAT collected from tenants and paid over to HMRC, and the Schedule E figures must be prepared so that VAT passing through is not mistaken for rental income or for a deductible cost. We reconcile the VAT returns to the rent ledger for each catch-up year for that reason.

Worked illustration: an office and warehouse unit in Manchester

The following is an illustration only. Every figure and exchange rate is assumed for the purpose of showing the mechanics and none should be read as a rate or threshold. A US citizen living in London bought a mixed office and warehouse unit ten years before the first catch-up year for GBP 2,000,000, of which a valuation attributes GBP 1,400,000 to the building and GBP 600,000 to land. The assumed exchange rate on the purchase date is USD 1.30 to the pound, giving a depreciable dollar basis of USD 1,820,000.

ADS straight-line depreciation over 40 years is USD 45,500 for each full year, ignoring the mid-month adjustment in the first year for simplicity. By the start of the three-year streamlined window, ten years of allowable depreciation, roughly USD 455,000, has already reduced the basis even though none was ever claimed. The three streamlined returns then claim USD 45,500 each, USD 136,500 in total.

In one of those years the rent is GBP 150,000 and deductible running costs and interest are GBP 30,000. At an assumed average rate of USD 1.25, that is USD 187,500 of rent and USD 37,500 of expenses, leaving USD 150,000 before depreciation and USD 104,500 after it. The UK return, with no structures and buildings allowance because the building predates the regime, shows a profit of GBP 120,000. Assume UK income tax on that profit of GBP 50,000, translated at USD 62,500.

On those assumptions the UK tax exceeds the US regular tax attributable to USD 104,500 of rental income, so the credit eliminates the regular tax on the rents and leaves an excess. If the whole USD 104,500 were subject to Net Investment Income Tax at 3.8%, that would be about USD 3,971 for the year, plus statutory interest. No streamlined penalty is added. The less visible number is the USD 455,000 of pre-window depreciation that has reduced basis without any deduction.

What happens when the property is sold later?

A sale is reported on the US return in dollars. Proceeds are translated at the rate on the sale date, and the adjusted basis is the original dollar cost, plus capitalised improvements at their own historic rates, less depreciation allowed or allowable. Because cost and proceeds are translated at different rates, the US gain can differ sharply from the sterling gain on the UK return.

The gain attributable to depreciation is unrecaptured section 1250 gain, taxed at a maximum 25%; the balance is long-term capital gain if the property was held for more than a year, and the Net Investment Income Tax can apply to the gain as well. UK Capital Gains Tax paid on the disposal is claimed on Form 1116, subject to the same category and limitation rules as the tax on the rents.
