You bought a flat in Bermondsey ten years ago for £385,000, picked up a Manchester Buy-to-Let three years ago for £165,000, and inherited a Yorkshire Dales cottage from your aunt last year, worth £435,000: three properties, three different US tax positions, and seven different UK taxes interacting across the lifecycle. The property tax US citizens UK property framework is one of the most consequential and most commonly mishandled areas of cross-border tax for American owners of UK real estate — and getting it wrong at purchase, during ownership, on disposal, or on inheritance produces material tax cost on both sides of the Atlantic that proper coordination would have avoided.
This guide is written for US citizens owning UK residential property, US citizens considering UK property purchase, US-UK dual citizens with UK property portfolios, and Americans inheriting UK property from UK-citizen relatives. By the end, you will have a thorough understanding of how each US federal position attaches, how each UK tax works, and how to work with both systems. For our broader cross-border service overview, see our US-UK cross-border tax advisory service.
The property tax US citizens UK property framework refers to the combined UK and US federal tax framework applying to UK residential property owned by a US citizen, Green Card holder, or US-UK dual citizen. On the UK side the framework covers Stamp Duty Land Tax (SDLT) on purchase under FA 2003 with rates including the post-April 2025 reduced bands, the 2 percent Non-Resident SDLT Surcharge under FA 2021 for non-UK-resident buyers, and the 5 percent Additional Property Surcharge under FA 2016 for second-home purchases; annual Council Tax under the Local Government Finance Act 1992; Annual Tax on Enveloped Dwellings (ATED) under FA 2013 for residential property held in corporate envelopes valued above £500,000; UK income tax on rental income on Self Assessment Property pages under ITTOIA 2005 Part 3; UK Capital Gains Tax on disposal under TCGA 1992 at 18 percent (basic-rate) and 24 percent (higher-rate) residential rates post-October 2024; and UK Inheritance Tax on death under IHTA 1984. HMRC SDLT guidance is available at https://www.gov.uk/stamp-duty-land-tax.
On the US side the framework covers Schedule E rental income reporting with IRC Section 168 alternative depreciation at the 30-year ADS rate on the building portion, Schedule D capital gain or loss on disposal with IRC Section 121 principal residence exclusion ($250,000 single / $500,000 joint) where applicable, Form 3520 on UK property inheritance over $100,000 from non-US-citizen decedents under IRC Section 6039F, Form 8938 FATCA disclosure of UK mortgage debt with UK lenders as “other foreign financial asset” under IRC Section 6038D, and Form 1116 Foreign Tax Credit relief on UK tax paid against US tax on the same income in the passive category.
This matters specifically in 2026 because UK Stamp Duty Land Tax rates returned to pre-2022 levels from 1 April 2025 with the nil-rate band reducing to £125,000 for owner-occupiers and £300,000 for first-time buyers, the UK Capital Gains Tax residential rates of 18 percent and 24 percent have been operating for nineteen months from the October 2024 Budget changes, and the 6 April 2025 UK Inheritance Tax long-term residence framework brings worldwide property of long-term UK residents into UK IHT scope from 6 April 2025 onwards.
Three reasons make the property tax position for US citizens in the UK particularly important in the 2025-26 tax year. First, the UK SDLT changes from 1 April 2025 restored the nil-rate band to £125,000 for owner-occupiers (down from £250,000 during the 2022-2025 holiday) and to £300,000 for first-time buyers (down from £425,000), meaningfully increasing SDLT costs on UK property purchases from April 2025 onwards. The HMRC SDLT calculator sits at https://www.gov.uk/stamp-duty-land-tax/residential-property-rates. US-citizen buyers of UK property in 2026 also face the 2 percent Non-Resident SDLT Surcharge under FA 2021 (cumulative on top of the standard rates and the 5 percent Additional Property Surcharge if applicable), making total SDLT on a £500,000 second home for a non-UK-resident US citizen approximately £52,500 (the standard SDLT of £15,000 plus the 5 percent ADS of £25,000 plus the 2 percent NRSS of £10,000, plus £2,500 surcharge interaction).
Second, the 6 April 2025 UK Inheritance Tax long-term residence framework under FA 2025 brought worldwide property of long-term UK residents into UK IHT scope. US citizens who have been UK residents for at least 10 of the previous 20 tax years now have their worldwide property (UK and US) within UK IHT at 40 percent above the available nil-rate band, with a 10-year IHT tail after departure. Our US-UK estate planning service covers the integrated US estate tax and UK IHT positioning under Article 8 of the US-UK Estate and Gift Tax Treaty.
Third, post-October 2024, UK Capital Gains Tax residential rates of 18 percent (basic-rate disposals) and 24 percent (higher-rate disposals) under FA 2024 provide US Foreign Tax Credit relief, typically eliminating or substantially reducing US tax on UK property disposal gains for higher-rate UK sellers. The interaction with IRC Section 121 principal residence exclusion ($250,000 single / $500,000 joint) on US-side gain calculation requires careful currency translation and US-dollar basis reconstruction.
UK Stamp Duty Land Tax on residential property purchase under FA 2003 applies to all UK property buyers, including US citizens. The post-April 2025 SDLT residential rates are 0 percent on the first £125,000, 2 percent on £125,001 to £250,000, 5 percent on £250,001 to £925,000, 10 percent on £925,001 to £1,500,000, and 12 percent above £1,500,000. The HMRC SDLT calculator at https://www.gov.uk/stamp-duty-land-tax/residential-property-rates produces the SDLT figure for any specific purchase.
The 2 percent Non-Resident SDLT Surcharge (NRSS) under FA 2021 applies cumulatively to UK property purchases by buyers who are not UK tax resident under the Statutory Residence Test (Schedule 45 FA 2013) during the relevant 365-day window around the transaction. US citizens living in the United States who purchase property are subject to NRSS; US citizens who are UK tax residents at the time of purchase are not.
The 5 percent Additional Property Surcharge under FA 2016 (post-October 2024 rate, up from 3 percent pre-October 2024) applies cumulatively on second-home and investment property purchases by buyers who already own residential property anywhere in the world. US-citizen UK Buy-to-Let buyers who also own a US primary residence or any other residential property typically face the 5 percent ADS on top of standard SDLT.
UK Council Tax under the Local Government Finance Act 1992 is the annual local government property tax payable by the property occupier (or the owner if vacant). Council Tax bands A through H apply based on the property’s 1991 valuation, with bands varying by local authority. Council Tax is a personal liability and not deductible on US Schedule E for owner-occupier properties; for UK Buy-to-Let properties where the landlord rather than the tenant pays Council Tax, it is deductible as a rental expense on UK Self Assessment Property pages and on US Schedule E.
The Annual Tax on Enveloped Dwellings (ATED) under FA 2013 applies to UK residential property valued at over £500,000 held within a corporate envelope (UK Limited company, US LLC treated as a corporation, offshore corporate vehicle). DATED bands run from approximately £4,400 per year for the £500,000-£1,000,000 band up to approximately £290,000 per year for the over £20 million band, with annual revaluation rules and reliefs available for genuine property rental businesses, property development, and other commercial uses. The HMRC ATED guidance sits at https://www.gov.uk/government/publications/annual-tax-on-enveloped-dwellings-the-basics.
UK rental income from Buy-to-Let, Houses in Multiple Occupation (HMO), Furnished Holiday Letting (FHL — abolished from April 2025 under FA 2025), and other UK rental property is taxable in the UK on Self Assessment Property pages under ITTOIA 2005 Part 3. UK landlord tax computation includes the 20 percent basic-rate mortgage interest restriction under FA 2017 Schedule 5 (mortgage interest no longer deducted from rental income but credited at basic rate against UK tax liability), allowable property expenses (letting agent fees, repairs, insurance, ground rent, service charges, Council Tax where landlord-paid), and the £1,000 UK property allowance for small-scale UK property income.
On the US side, UK rental income is reported on Form 1040, Schedule E, with each property treated as a separate Schedule E unit. Gross rental income is translated to US dollars at year-end average exchange rates published at https://www.irs.gov/individuals/international-taxpayers/yearly-average-currency-exchange-rates. Allowable US expenses include UK mortgage interest in full (no UK-style restriction on the US side), letting agent fees, repairs, insurance, ground rent, service charges, Council Tax (where landlord-paid), and IRC Section 168 alternative depreciation at the 30-year ADS rate on the building portion of the US-dollar acquisition cost (land is not depreciable).
The first step is the pre-purchase tax modeling. US-citizen buyers should model total SDLT exposure (standard SDLT plus NRSS for non-UK-resident buyers plus ADS for second-home purchases) before any UK property purchase, plus the ongoing US Schedule E rental position if the property will be let, plus the eventual UK CGT and US Schedule D position on disposal. HMRC SDLT guidance is available at https://www.gov.uk/stamp-duty-land-tax.
The second step is documenting historical acquisition costs. US citizens should document the US-dollar acquisition cost of every UK property at the historical exchange rate on the completion date, retain solicitor completion statements, retain Council Tax registration documents, and retain mortgage documentation. The US-dollar acquisition cost is the basis for IRC Section 168 depreciation and eventual IRC Section 121 / Schedule D disposal gain calculation.
The third step is the annual rental position management. For UK Buy-to-Let, holiday let, and other UK rental property, UK Self Assessment Property pages are filed annually by 31 January for the prior 5 April UK tax year, with allowable UK expenses, FA 2017 Schedule 5 mortgage interest restriction, and the £1,000 UK property allowance applied. US Schedule E is filed annually on Form 1040 by 15 June (expat extension) or 15 October (Form 4868 extension), with IRC Section 168 alternative depreciation, full US-side mortgage interest deduction, and Form 1116 FTC in the passive category for UK tax paid.
The fourth step is the coordination of UK CGT and US Schedule D on disposal. UK CGT on UK residential property disposal applies at 18 percent basic-rate or 24 percent higher-rate post-October 2024 rates with the £3,000 annual exempt amount (2025-26 reduced from £6,000 in 2023-24 and £12,300 in 2022-23). UK CGT must be reported within 60 days of disposal via the HMRC online Capital Gains Tax service. The HMRC CGT on UK property service sits at https://www.gov.uk/report-capital-gains-tax-uk-property. On the US side, the disposal is reported on Schedule D with the US-dollar gain calculated between US-dollar sale proceeds and US-dollar historical acquisition cost (plus depreciation recapture under IRC Section 1250 on Section 168 depreciation claimed during ownership). IRC Section 121 principal residence exclusion of $250,000 (single) or $500,000 (married filing jointly) applies if the property has been owned and used as a primary residence for at least two of the five years preceding the sale. UK CGT paid is creditable on Form 1116 in the passive category.
The fifth step is the Form 3520 reporting on UK property inheritance. UK property inherited from a non-US-citizen decedent valued at over $100,000 triggers Form 3520 filing under IRC Section 6039F. The IRS Form 3520 reference sits at https://www.irs.gov/forms-pubs/about-form-3520. The inheritance receipt itself is not US income-taxable, but the missed Form 3520 is subject to a 5 percent per-month penalty, up to 25 percent of the unreported inheritance value. IRC Section 1014 basis step-up applies on the US side to the fair market value of the UK property at the date of death, providing valuable basis uplift for eventual disposal Schedule D calculation.
The sixth step is the Form 8938 FATCA disclosure of UK mortgage debt. UK mortgage debt held with Lloyds, Nationwide, HSBC UK, Barclays UK, Santander UK, NatWest, Halifax, or any other UK lender is reportable on Form 8938 as “other foreign financial asset” under IRC Section 6038D once the UK-resident specified asset thresholds are crossed ($200,000 year-end or $300,000 peak for single; $400,000 year-end or $600,000 peak for married filing jointly). The mortgage is reported at the year-end balance and peak balance for each year.
The seventh step is the integrated annual compliance. UK Self Assessment for the UK rental position, plus US Form 1040 with Schedule E plus Form 8938 FATCA on UK mortgage debt, plus Form 1116 FTC across general and passive categories, plus Form 8833 supporting treaty positions, all need to be coordinated annually under specialist engagement.
Emma is a US-UK dual citizen, aged forty-four, born in London to a US citizen father and a UK citizen mother, and a UK resident throughout her life. She works as a senior management consultant on a £145,000 salary plus £35,000 annual bonus. She had acquired three UK properties over the past decade. First, a primary residence flat in Bermondsey purchased in 2014 for £385,000 with a Lloyds mortgage of £180,000 (current value approximately £540,000, no current mortgage after early 2024 repayment). Second, a Manchester Buy-to-Let purchased in 2019 for £165,000 with a Lloyds mortgage of £108,000, generating approximately £14,000 of annual gross rental income (current value approximately £195,000, outstanding Lloyds mortgage of £98,000). Third, an inherited Yorkshire Dales cottage from her UK-citizen aunt in mid-2023, valued at £435,000 at the date of death, used as a holiday let generating approximately £18,000 of annual gross rental income from 2023 onwards.
Emma had been filing UK Self Assessment correctly each year through a generalist Manchester accountant — UK rental income from the Manchester BTL and the Yorkshire cottage on the Property pages of the Self Assessment, UK Inheritance Tax disclosed to HMRC for the Yorkshire cottage inheritance (no UK IHT was payable because her aunt’s estate fell below the £325,000 nil-rate band after lifetime gift adjustments), and SDLT paid correctly on each acquisition. She had not been filing any US Form 1040 based on her UK-only upbringing — the dual citizenship status had been a passive birthright that she had not previously understood to create US tax obligations.
In late 2025, Emma’s HSBC personal banker mentioned FATCA in passing during an account review meeting. Emma engaged Jungle Tax in December 2025. The cross-border review identified eight immediate exposure points.
First, Emma met the IRS Streamlined Foreign Offshore Procedures eligibility — 330-day non-US residency test in all three of 2022, 2023, and 2024, non-willful past non-compliance, no IRS contact made.
Second, the Bermondsey primary residence required no current Schedule E reporting. Still, the US-dollar acquisition cost at the August 2014 historical exchange rate was documented at $640,000 for future Schedule D purposes when she eventually sells. IRC Section 121 principal residence exclusion would apply on eventual sale ($250,000 single under her current filing position).
Third, the Manchester Buy-to-Let required Schedule E reporting for each Streamlined year (2022, 2023, 2024). UK gross rent of £14,000 annually translated to approximately $17,500 USD. UK allowable expenses (Lloyds mortgage interest, letting agent fees, repairs, ground rent, service charges, accountant fees, Council Tax) totaled approximately £7,200 annually. IRC Section 168 alternative depreciation at the 30-year rate was elected on the building portion of the original $210,000 US-dollar acquisition cost (assumed 80 percent building / 20 percent land split), adding approximately $5,600 of annual depreciation deduction. Net Schedule E position for each year was a small US-dollar loss of approximately $3,000 to $4,000, suspended under IRC Section 469 passive activity loss rules pending future passive income offset or disposal.
Fourth, the Yorkshire Dales cottage required Form 3520 filing for the 2023 inheritance receipt. The £435,000 value at the date of death in mid-2023 translated to approximately $554,000 USD at the year-end average exchange rate, well above the $100,000 Form 3520 threshold for inheritances from non-US-citizen decedents. The cottage was then reported on Schedule E for 2023 (a partial year from the inheritance date) and 2024 (a full year) as holiday let rental income, with the US-dollar acquisition basis stepped up to the $554,000 inheritance value under IRC Section 1014.
Fifth, UK mortgage debt at Lloyds on the Manchester Buy-to-Let (approximately $137,000 in US-dollar terms) was Form 8938-reportable as “other foreign financial asset” attached to each of the 2022, 2023, and 2024 Streamlined returns. The Bermondsey primary residence mortgage had been repaid in early 2024, but was Form 8938-reportable for the 2022 and 2023 years. The inherited Yorkshire cottage had no mortgage.
Sixth, Form 1116 Foreign Tax Credit absorbed all US federal tax on Emma’s £145,000 UK salary and £35,000 UK bonus across the three Streamlined years through the general category FTC, with approximately $18,000 of annual excess FTC carryforward generated under IRC Section 904(c) available for the next ten years. The passive category FTC on UK rental tax was minimal because the UK rental tax position was already net of significant UK allowable expenses.
Seventh, the post-April 2025 UK Inheritance Tax long-term residence framework brought Emma firmly within UK IHT worldwide scope from 6 April 2025 — Emma had been a UK resident for her entire life, well past the 10-of-20-years threshold. Her entire worldwide property would be subject to UK IHT at 40 percent above the available nil-rate band (£325,000 plus £175,000 residence nil-rate band for direct descendants, where applicable) on death. US estate tax would also apply to her worldwide estate as a US citizen, with Article 8 of the US-UK Estate and Gift Tax Treaty providing relief but not elimination, needed for planning.
Eighth, the post-October 2024 UK CGT residential rates of 18 percent and 24 percent meant that any eventual disposal of the Bermondsey flat or Manchester BTL would produce UK CGT at the higher-rate 24 percent on Emma’s gain above the £3,000 annual exempt amount, with the UK CGT creditable on Form 1116 in the passive category against US Schedule D tax on the same gain.
The remediation route used the Streamlined Foreign Offshore Procedures package with extensive UK property handling. Three years of Form 1040 (2022, 2023, 2024) were prepared with Form 1116 FTC absorbing all US federal tax, Schedule E reporting the Manchester BTL with IRC Section 168 depreciation across all three years and the Yorkshire cottage from mid-2023, Form 3520 disclosing the 2023 inheritance, Form 8938 disclosing UK mortgage debt across each year, six years of FBARs (2019 through 2024) covering Emma’s HSBC current and savings accounts plus a NatWest joint account with her UK husband, Form 14653 non-willfulness narrative explaining Emma’s UK-only upbringing and unknown US tax obligation status. The Streamlined package was submitted in March 2026.
Going-forward estate planning under Article 8 of the US-UK Estate and Gift Tax Treaty was scheduled for separate engagement covering the UK IHT long-term residence framework integration with US estate tax positioning, beneficiary designation review, lifetime gifting strategy under the US annual exclusion and lifetime exemption versus UK potentially exempt transfer rules, and UK pension death benefit treatment under the post-April 2027 UK IHT pension inclusion framework.
The outcome was full IRS compliance under the Streamlined Foreign Offshore Procedures with zero federal penalties (against potential Form 3520 missed-filing exposure on the Yorkshire cottage inheritance of approximately £108,000 plus FBAR, Form 8938, and Form 1040 exposure approaching £80,000), zero net US income tax across the three covered years through optimised Form 1116 FTC, $54,000 of accumulated general category FTC carryforward, Schedule E baseline established for both rental properties going forward, Form 3520 inheritance baseline established for the Yorkshire cottage with IRC Section 1014 basis step-up to $554,000, Form 8938 disclosure of Lloyds mortgage in place going forward, and an integrated US-UK estate planning engagement scheduled. Total Jungle Tax fee approximately £5,400 for the Streamlined plus first-year ongoing engagement, against avoided exposure of approximately £188,000.
The first mistake is assuming UK rental income is not US-taxable because the UK landlord tax computation under FA 2017 Schedule 5 mortgage interest restriction produces minimal UK tax. The US Schedule E calculation operates independently and typically produces meaningful US tax position before Form 1116 FTC relief.
The second mistake is failing to claim IRC Section 168 alternative depreciation on UK Buy-to-Let buildings. Depreciation under the 30-year alternative depreciation system produces an approximately 3.3 percent annual deduction on the building portion of the acquisition cost, materially reducing Schedule E US-taxable rental income.
The third mistake is failing to file Form 3520 for UK property inheritance valued at over $100,000. The IRS Form 3520 reference is available at https://www.irs.gov/forms-pubs/about-form-3520. The receipt itself is not US income-taxable, but a missed Form 3520 attracts a 5 percent per-month penalty, up to 25 percent of the unreported inheritance value.
The fourth mistake is failing to claim IRC Section 1014 basis step-up on inherited UK property. The US-dollar fair market value at the date of death becomes the new US tax basis, providing valuable basis uplift for eventual Schedule D disposal calculation.
The fifth mistake is missing the 2 percent Non-Resident SDLT Surcharge on UK property purchase by US-citizen buyers not yet UK tax resident. US citizens still living in the United States buying UK property are subject to the 2 percent NRSS, cumulatively on top of standard SDLT, and, if applicable, the 5 percent Additional Property Surcharge.
The sixth mistake is failing to report UK mortgage debt on Form 8938. The UK property itself is not Form 8938-reportable (real estate is excluded from specified foreign financial assets under IRC Section 6038D), but UK mortgage debt held with a UK lender is reportable as “other foreign financial asset” once specified asset thresholds are met.

Three takeaways matter most for US citizens owning UK property in 2026. First, the property tax US citizens UK property framework spans seven UK taxes (SDLT including the 2 percent Non-Resident SDLT Surcharge and 5 percent Additional Property Surcharge, Council Tax, ATED on corporate envelopes, UK income tax on rental, UK CGT at post-October 2024 rates of 18 percent and 24 percent residential, UK Inheritance Tax under the 6 April 2025 long-term residence framework) plus four US federal positions (Schedule E rental with IRC Section 168 alternative depreciation, Schedule D disposal gain with IRC Section 121 principal residence exclusion, Form 3520 inheritance over $100,000 with IRC Section 1014 basis step-up, Form 8938 FATCA on UK mortgage debt) — coordinated cross-border specialist input materially outperforms single-jurisdiction handling. Second, direct UK property ownership itself is not FBAR-reportable or Form 8938-reportable (real estate is excluded under both frameworks). Still, UK mortgage debt with a UK lender is Form 8938-reportable as “other foreign financial asset” under IRC Section 6038D once thresholds are met. Every income, gain, and inheritance flow from the property is fully US-reportable. Third, the post-April 2025 UK IHT long-term residence framework brings worldwide property of long-term UK residents into UK IHT scope, requiring integrated US-UK estate planning under Article 8 of the US-UK Estate and Gift Tax Treaty for US-citizen UK property owners with 10 of 20 years of UK residence.

Yes for the reporting, with Foreign Tax Credit relief eliminating most or all US tax. UK rental income is taxable in the UK on Self Assessment Property pages under ITTOIA 2005 Part 3 with FA 2017 Schedule 5 mortgage interest restriction. It is fully reportable on US Form 1040 Schedule E with each property as a separate Schedule E unit, including IRC Section 168 alternative depreciation at the 30-year ADS rate on the building portion. Form 1116 Foreign Tax Credit in the passive category relieves UK tax already paid against US tax on the same income. The Net Schedule E position is often a small US-dollar loss because US-side allowable expenses, including the full mortgage interest deduction and IRC Section 168 depreciation, are more generous than the UK FA 2017-restricted position.
Yes, if you are not a UK tax resident under the Statutory Residence Test (Schedule 45 FA 2013) during the relevant 365-day window around the transaction. The 2 percent Non-Resident SDLT Surcharge under FA 2021 applies cumulatively to UK property purchases by buyers who are not UK tax residents, on top of the standard SDLT rates and the 5 percent Additional Property Surcharge if applicable. US citizens who are also UK tax residents at the time of purchase are not subject to NRSS. For a £500,000 UK second home purchased by a US-resident US citizen, total SDLT exposure (standard + ADS + NRSS) is approximately £52,500.
Not the property itself; yes for related items. Direct ownership of UK real estate is excluded from FBAR under the Bank Secrecy Act and from Form 8938 specified foreign financial assets under IRC Section 6038D. UK bank accounts used to receive UK rental income are FBAR-reportable; UK mortgage debt with a UK lender (Lloyds, Nationwide, HSBC UK, Barclays UK, Santander UK, NatWest, Halifax) is Form 8938-reportable as “other foreign financial asset” once specified asset thresholds are met; UK rental income is fully reportable on Form 1040 Schedule E.
Yes, if the inheritance value exceeds $100,000. Form 3520 (Annual Return To Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts) is required under IRC Section 6039F for receipts of gifts or bequests from non-US-citizen foreign persons exceeding $100,000 in a single tax year. Form 3520 is filed separately with the IRS Ogden Service Center, with a copy attached to the relevant year’s Form 1040. The inheritance itself is not US income-taxable to the recipient under IRC Section 102, and IRC Section 1014 provides basis step-up to the fair market value at the date of death. Missed Form 3520 attracts 5 percent per month up to 25 percent of the unreported inheritance value.
On Form 1040 Schedule D with IRC Section 121 principal residence exclusion, where applicable. The US-dollar gain is calculated by comparing US-dollar sale proceeds (at the disposal date exchange rate) with US-dollar historical acquisition cost (at the acquisition date exchange rate), with currency movements producing US tax effects independent of the UK CGT calculation. IRC Section 121 principal residence exclusion of $250,000 (single) or $500,000 (married filing jointly) applies if the property has been owned and used as a primary residence for at least two of the five years preceding the sale. Post-October 2024 UK CGT at 18 percent or 24 percent residential rates is creditable on Form 1116 in the passive category against US Schedule D tax on the gain.
Yes. Foreign rental property is depreciable under IRC Section 168, the alternative depreciation system, at the 30-year rate on the building portion of the acquisition cost (land is not depreciable). For a UK Buy-to-Let with US-dollar acquisition cost of $300,000, of which $240,000 is building, and $60,000 is land, annual depreciation is approximately $8,000 (240,000 / 30). Depreciation materially reduces the US-side Schedule E taxable rental income, with eventual depreciation recapture under IRC Section 1250 at a maximum 25 percent rate on disposal
Yes, if you have been UK resident for at least 10 of the previous 20 tax years. The 6 April 2025 UK IHT long-term residence framework under FA 2025 brought worldwide property of long-term UK residents into UK IHT scope at 40 percent above the available nil-rate band (£325,000 plus £175,000 residence nil-rate band where direct descendants inherit), with a 10-year IHT tail after departure. For long-term UK-resident American property owners, integrated US estate tax and UK IHT planning under Article 8 of the US-UK Estate and Gift Tax Treaty
