How the IRC §911 Foreign Housing Exclusion Works in 2026
U.S. citizens and resident aliens working abroad can exclude foreign housing costs that exceed the "base housing amount" from their U.S. taxable income under IRC §911. For 2026, the FEIE is $130,000 and the annual base housing amount is 16% of $130,000 = $20,800 (prorated for days abroad). The base amount represents what the IRS assumes a U.S.-based worker spends on housing domestically. Housing costs above the base — up to the city-specific ceiling — are excludable. This is in addition to the $130,000 FEIE. Claim on IRS Form 2555. Source: IRC §911; IRS Publication 54. Last updated: May 2026.

Qualifying for the Housing Exclusion and What Costs Count
To qualify for the §911 housing exclusion, you must meet either the bona fide residence test (a full tax year as a bona fide resident of a foreign country) or the physical presence test (330 full days in a foreign country within any 12-month period). Qualifying housing expenses include: rent, utilities (electricity, gas, water — but not telephone/internet), household insurance, residential parking fees, and furniture rental. Non-qualifying expenses include: mortgage principal and interest payments, property taxes, lavish or extravagant costs, and expenses for a second home. Always use IRS Notice (published each spring) for the current year's city-specific ceilings — ceilings are updated annually.
