Introduction: The Foreign Housing Exclusion in 2026
The foreign housing exclusion allows Americans living in London to shelter up to $47,336 of rent and related costs from US tax in 2026, entirely on top of the Foreign Earned Income Exclusion. Furthermore, that figure rose this year, and most published guidance has not caught up. Consequently, wealthy filers across the capital are quietly under-claiming a benefit they have already paid for in rent.
London carries one of the highest housing caps the IRS publishes anywhere in the world, and the rules bind every US citizen resident abroad who files. Additionally, the capital sits inside a patchwork of UK-specific limits that reward some postcodes generously and ignore others completely. Therefore, the difference between a correctly prepared Form 2555 and a careless one runs into five figures every year for senior professionals.
At TaxYork, we prepare returns for investment bankers, fund principals, company owners and senior executives across the City, Canary Wharf and the commuter belt. Moreover, we see the same expensive mistakes repeatedly. This guide sets out exactly what the foreign housing exclusion delivers in 2026, which costs qualify, and where the genuine traps sit for high-net-worth filers.
Foreign Housing Exclusion Explained for Americans in London
The foreign housing exclusion is a provision under section 911 of the Internal Revenue Code that lets a qualifying American abroad exclude reasonable housing costs from US taxable income. Specifically, it captures the portion of your housing spend that exceeds a government-set baseline, subject to a geographic cap. Accordingly, it rewards precisely the people paying premium rents in expensive cities.
How the Foreign Housing Exclusion Differs From the FEIE
The Foreign Earned Income Exclusion and the foreign housing exclusion are separate benefits claimed on the same form. Furthermore, they stack. The Foreign Earned Income Exclusion shelters $132,900 of earnings in 2026, while the housing provision shelters a further slice tied to what you actually spend on accommodation.
Many filers assume the $132,900 figure is the ceiling. However, that assumption costs London-based professionals dearly, as the IRS guidance on figuring the exclusion makes clear. Additionally, the housing benefit requires no extra qualifying test beyond the one you already meet for the FEIE itself. Therefore, if you qualify for one, you almost certainly qualify for both.
Who Qualifies: Bona Fide Residence and Physical Presence
To claim the foreign housing exclusion, you must hold a tax home in a foreign country and satisfy one of two tests. The bona fide residence test requires uninterrupted residence abroad for an entire calendar year. Alternatively, the physical presence test requires 330 full days abroad in any rolling twelve-month period.
Most settled Americans in London meet the bona fide residence test comfortably. Nevertheless, the test examines intent and permanence, not merely day count. Consequently, a two-year secondment with a fixed end date and a retained US home can fail it, even where the physical presence test succeeds.
Why the Tax Home Test Trips Up Frequent Travellers
Your tax home must sit outside the United States for the entire qualifying period. Notably, this defeats many senior dealmakers. For instance, a partner who keeps a Manhattan apartment, spends ninety nights a year in New York and bills significant US work may find the IRS treats her abode as American.
The rule matters more at the top of the income scale. Moreover, wealthy filers travel far more than average. Therefore, we test the tax home position before claiming anything, because a failed tax home invalidates the FEIE and the foreign housing exclusion simultaneously.
The 2026 Numbers: What London Filers Can Actually Exclude
The IRS publishes adjusted housing limits annually. Specifically, Notice 2026-25 governs the 2026 tax year and sets the figures every London filer needs. Furthermore, these numbers changed from 2025, which is where most online guidance now misleads readers.
The Base Amount and the London Cap
Two figures drive the calculation. Firstly, the base housing amount for 2026 is $21,264, being sixteen per cent of the $132,900 FEIE. Secondly, the London cap is $68,600 for a full year, equivalent to $187.95 per day. Accordingly, the maximum foreign housing exclusion available to a London filer in 2026 is $47,336.
That $47,336 represents $68,600 less the $21,264 base. Importantly, the generally applicable cap for ordinary locations is only $39,870, which would yield just $18,606. Therefore, London status is worth an additional $28,730 of shelter to anyone spending enough on rent.
Why Most Published Guides Still Quote $67,000
We reviewed the pages currently ranking for this topic. Notably, the leading guides state the London cap as $67,000. However, $67,000 was the 2025 figure published in Notice 2025-16, alongside a $130,000 FEIE and a $20,800 base amount.
The current London cap is $68,600, not $67,000. Consequently, guidance quoting the older figure understates the available shelter by $1,600 and understates the net foreign housing exclusion by $1,136. Additionally, anyone applying the stale $20,800 base to a 2026 return will misstate the calculation on both sides.
The Combined Shield: $180,236
Stack the two benefits and a qualifying London filer shelters $180,236 of foreign earned income in 2026. Specifically, that is $132,900 of FEIE plus $47,336 of housing benefit. Furthermore, married couples where both spouses work and maintain qualifying status can each claim the FEIE, though the household generally supports only one housing exclusion.
For a filer in the 35 per cent bracket, that combined shield is worth roughly $63,000 of US tax. Nevertheless, the headline figure flatters the reality for many wealthy Londoners, for reasons we examine below.
The UK Postcode Lottery Nobody Writes About
Competitor guidance treats "London" as though it were the only UK entry in the IRS table. In fact, Notice 2026-25 lists twelve separate UK localities plus a catch-all. Moreover, the spread between them is enormous, and several results defy intuition.
Caversham Beats London
The highest UK housing cap for 2026 does not belong to London. Instead, Caversham carries a cap of $73,800, exceeding the London figure by $5,200. Similarly, Bracknell, High Wycombe and Reading share a cap of $62,100, while Loudwater reaches $57,400.
These figures reflect historic diplomatic and defence posting data rather than current market rents. Nevertheless, they bind the calculation. Therefore, a fund manager living in Caversham and commuting to Paddington claims a larger foreign housing exclusion than an identical colleague in Kensington.
Surrey, Farnborough and the Commuter Belt
Surrey carries its own cap of $48,402, some $20,198 below London. Additionally, Farnborough sits at $54,700 and Cheltenham at $54,300. Basingstoke and Bath sit near the bottom of the named list at $41,099 and $41,000 respectively.
The Surrey figure catches many wealthy families. Specifically, executives who move from a London flat to a house in Esher or Weybridge often assume their cap follows them. However, it drops by more than $20,000, cutting the available foreign housing exclusion accordingly.
Edinburgh, Birmingham and Bristol Get Nothing
Several major UK cities receive no uplift whatsoever. Notably, Notice 2026-25 expressly excludes Birmingham, Bristol, Cambridge, Edinburgh, Belfast, Liverpool, Nottingham, Oxfordshire, Plymouth, Portsmouth and Chelmsford from the enhanced UK rate. Consequently, filers in those cities fall back to the generally applicable $39,870.
Everywhere else in the United Kingdom not separately named attracts a cap of $44,200. Therefore, an American in Manchester or Leeds claims $22,936 of housing benefit at most. Meanwhile, the identical family in London claims $47,336, more than double.
Which Costs Qualify and Which Wealthy Filers Wrongly Claim
The definition of qualified housing expenses is narrower than most assume. Furthermore, high earners consistently over-claim in three predictable areas. IRS guidance on the housing exclusion and Publication 54 govern the boundaries.
Qualifying Expenses for London Tenants
Rent forms the bulk of any London claim under the foreign housing exclusion. Additionally, you may include utilities other than telephone and internet, property and contents insurance, occupancy taxes, non-refundable deposits and letting fees, furniture rental, residential parking and repairs. Accordingly, council tax generally qualifies as an occupancy tax, which many filers omit entirely.
Estate agency fees, tenancy renewal fees and inventory charges also count. Moreover, these routinely exceed £2,000 a year in prime London. Therefore, capturing them properly can add several thousand dollars to the claim at no additional cost to the client.
The Mortgage Trap for Owner-Occupiers
Mortgage principal never qualifies. Furthermore, mortgage interest does not qualify for the foreign housing exclusion either, which surprises many wealthy buyers. Similarly, the purchase price, stamp duty land tax, capital improvements and anything the IRS treats as a capital cost all fall outside the provision.
This creates a structural asymmetry. Specifically, an American renting a £5,000-per-month flat in Marylebone claims a substantial housing exclusion, while a neighbour servicing an equivalent mortgage claims almost nothing. Nevertheless, owner-occupiers may still include utilities, insurance, repairs and council tax.
Lavish or Extravagant: The Rule That Bites in Mayfair
The statute excludes expenses that are lavish or extravagant in the circumstances. Importantly, the London cap of $68,600 already truncates most claims before this rule engages. However, filers spending £15,000 a month on a Mayfair townhouse should expect scrutiny of ancillary items rather than the rent itself.
Domestic staff costs illustrate the point. Specifically, a housekeeper's wages are not a housing expense, notwithstanding that the household could not function without one. Therefore, we exclude them, and we document the reasoning on file.
Case Study: A Canary Wharf Managing Director
Consider James, a US citizen and managing director at an investment bank in Canary Wharf, resident in the UK since 2019 and comfortably bona fide resident. His 2026 salary and bonus total £310,000, roughly $395,000. Furthermore, he rents a riverside flat in Wapping.
His housing costs run to £5,200 a month in rent, or £62,400 annually, equal to about $79,500. Additionally, he pays £2,400 in utilities, £600 in contents insurance, £2,300 in council tax and £2,900 for secure parking. His qualified expenses therefore reach approximately $89,900.
Because his spend exceeds the $68,600 London cap, James claims the maximum. Consequently, his foreign housing exclusion is $47,336, and his combined shelter with the FEIE reaches $180,236. On the face of it, he has saved roughly $63,000.
The complete analysis proves more nuanced. Specifically, James pays UK tax at the 45 per cent additional rate, producing a UK liability near $163,000, which comfortably exceeds his entire US liability on the same income. Therefore, the foreign tax credit alone would reduce his US tax to nil without any exclusion at all.
Electing the exclusions actively harms him. Firstly, section 911(d)(6) requires him to disallow the portion of UK tax attributable to excluded income, destroying roughly $74,000 of creditable foreign tax. Secondly, section 911(f) taxes his remaining income at the marginal rates that would have applied had nothing been excluded. Accordingly, we prepared James's return on a credit-only basis and preserved a substantial carryforward.
His colleague Sarah presents the opposite case. Notably, she earns $210,000, spends half her year on non-UK assignments and pays materially less UK tax. Therefore, the foreign housing exclusion and FEIE together deliver her a genuine five-figure saving that credits alone cannot match.
Strategic Traps for High-Net-Worth Filers
The foreign housing exclusion rewards careful preparation and punishes reflexive elections. Furthermore, three provisions catch wealthy filers repeatedly. We test each one before signing any return.
The Stacking Rule Under Section 911(f)
Excluded income does not vanish from the rate calculation. Specifically, section 911(f) requires you to compute tax on your remaining income at the brackets that would apply if the excluded amounts were still included. Consequently, the first dollar of non-excluded income is taxed near the top of the schedule.
Many filers model the benefit as though exclusion removed income from the bottom of the stack. However, it removes it from the bottom while preserving the rates from the top. Therefore, the true value of a $180,236 shelter is materially lower than a naive calculation suggests.
Why Claiming the Exclusion Can Cost You Foreign Tax Credits
Foreign taxes attributable to excluded income become non-creditable. Additionally, the UK taxes most Americans in London at rates well above equivalent US rates. Accordingly, high earners frequently hold surplus credits that would eliminate their US liability entirely without recourse to any exclusion.
The interaction runs both ways. Notably, excess credits under Form 1116 carry back one year and forward ten. Therefore, sacrificing credits today to claim an exclusion that saves nothing is a genuine and common error, and one worth reviewing across several open years.
The Five-Year Revocation Lock
Once you revoke a section 911 election, you cannot reclaim it for five tax years without formal IRS consent. Furthermore, obtaining that consent requires a private letter ruling and a substantial user fee. Consequently, the decision to switch between exclusion and credit deserves real modelling rather than a default.
We therefore project the position across a multi-year horizon. For instance, a client approaching a liquidity event, a move to a lower-tax jurisdiction or a period of US-source income may need the exclusion available later. Accordingly, preserving optionality often outweighs a marginal current-year saving.
Self-Employed Americans and the Foreign Housing Deduction
Business owners and consultants cannot claim the exclusion. Instead, they claim the foreign housing deduction, which achieves a similar result through a different mechanism. Moreover, the distinction carries practical consequences that catch many company principals.
Where the Deduction Sits on Form 2555
Employees complete the housing exclusion parts of Form 2555, while the self-employed complete the deduction parts. Additionally, the deduction flows to Schedule 1 as an adjustment to income rather than reducing gross income directly. Therefore, it reduces adjusted gross income, which affects a range of downstream thresholds.
The deduction cannot exceed your foreign earned income less amounts already excluded. Nevertheless, any disallowed portion carries forward one tax year. Consequently, a principal with a lumpy income profile should track the carryover deliberately rather than losing it.
Self-Employment Tax and the Totalization Agreement
Neither the exclusion nor the deduction reduces self-employment tax. Specifically, the 15.3 per cent charge applies to net earnings regardless of how much income you exclude. However, the US-UK totalization agreement resolves this for most self-employed Americans genuinely based in Britain.
Where you pay UK National Insurance and hold a certificate of coverage from HMRC, US self-employment tax does not apply. Furthermore, this single document often saves more than the housing deduction itself. Therefore, we secure it as a matter of course for self-employed clients.
Missed the Foreign Housing Exclusion on Earlier Returns
Under-claiming is common, and it is usually fixable. Furthermore, we regularly recover meaningful sums for clients who filed through generalist preparers unfamiliar with the high-cost locality tables.
Amending Within the Three-Year Window
You may generally amend a return within three years of filing or two years of paying the tax, whichever is later. Accordingly, a London filer who omitted the foreign housing exclusion across three open years may recover a substantial refund. Additionally, we routinely find omitted council tax, parking and letting fees even where the core claim was made.
When Streamlined Filing Is the Better Route
Some Americans discover the housing rules only when they discover they should have been filing at all. In that case, amendment is not the correct mechanism. Instead, the IRS Streamlined Filing Compliance Procedures bring you current on three years of returns and six years of FBARs without penalty, where the failure was non-wilful.
Crucially, a properly prepared streamlined submission claims the exclusions retrospectively. Therefore, many clients complete the programme owing nothing. Our IRS Streamlined Filing service handles the full submission, and our FBAR and FATCA reporting team addresses the parallel foreign account obligations.
How TaxYork Can Help
We prepare US and UK returns for high-net-worth individuals, investors, company owners and senior finance professionals across Britain. Furthermore, we model the exclusion against the credit position every year rather than defaulting to whichever route the prior preparer chose.
Our work covers US tax return preparation for expats, tax treaty optimisation and cross-border compliance for dual filers. Additionally, we coordinate the US and UK positions together, because treating them separately is where value leaks.
We verify every locality cap against the current IRS notice, capture the ancillary expenses generalists miss, and document the tax home position properly. Consequently, our clients claim the full foreign housing exclusion they are entitled to, and only where claiming it genuinely helps.
Conclusion
The foreign housing exclusion delivers up to $47,336 of additional shelter for London filers in 2026, on top of the $132,900 FEIE. Furthermore, the London cap rose to $68,600 this year, a change most published guidance has yet to reflect.
The headline figure alone should not drive your return. Specifically, the stacking rule, the disallowance of credits attributable to excluded income, and the five-year revocation lock mean that many high earners in London do better on a credit-only basis. Therefore, the correct answer depends on your rates, your travel pattern and your plans.
Above all, verify your actual locality cap before assuming London rates apply. Additionally, check whether earlier returns omitted the claim entirely. Ultimately, precise preparation converts a complicated provision into a reliable annual saving.
