US expat exclusions and deductions

Sometimes — cancelled mortgage debt is taxable income by default, but the Qualified Principal Residence Indebtedness exclusion can shelter up to $750,000 ($375,000 if married filing separately) of forgiven mortgage debt on your main home, for discharges occurring before January 1, 2026. That deadline matters: unless Congress extends it again, debt forgiven on or after that date generally loses this specific exclusion. Separately, if your total debts exceeded your total assets right before the cancellation, the insolvency exclusion can shelter some or all of the forgiven amount regardless of that deadline — see the full rules on Form 1099-C and cancelled debt for how to calculate and report either exclusion.

Yes — the Section 121 home sale exclusion isn't limited to US-located property, so selling a foreign home you owned and lived in as your main residence for at least 2 of the last 5 years can qualify for the same $250,000 (single) or $500,000 (married filing jointly) gain exclusion. The catch is currency conversion: your gain is calculated in US dollars, using exchange rates on the purchase and sale dates, so a favorable currency shift alone can create a taxable US-dollar gain even if the sale price barely moved in local currency. It's worth running the exchange-rate math before assuming a foreign home sale will be tax-free.

It can, but historically only if you itemize and give to a US-recognized 501(c)(3) — donations to purely foreign charities generally don't count on a US return, with narrow treaty exceptions. That's changing soon: starting with the 2026 tax year, a new above-the-line charitable deduction lets even standard-deduction filers deduct up to $1,000 ($2,000 married filing jointly) in cash gifts to qualifying US charities, without itemizing at all. Until then, if you're taking the standard deduction, your 2025 charitable giving generally won't move your refund.

Yes — US citizens and green card holders abroad claim the same standard deduction as anyone filing from within the US: $15,750 for single filers and $31,500 for married filing jointly in 2025. Living abroad doesn't reduce or restrict it. The only people who generally can't use it are nonresident aliens filing Form 1040-NR, which is a different filing status entirely from a US citizen or resident living overseas — see the full standard vs. itemized comparison for when itemizing might actually beat it.

Not many line-item deductions exist purely because you live abroad — most of the expat-specific tax relief comes as exclusions and credits instead, with the Foreign Housing Exclusion being the closest thing to a "living abroad" deduction. It lets you exclude (or, if self-employed, deduct) qualifying housing costs above a base amount, specifically because those costs are tied to living outside the US. Beyond that, self-employed expats deduct ordinary business expenses the same way any US-based business owner would — there's no special expanded deduction just for operating from overseas.

MAGI (Modified Adjusted Gross Income) starts with your regular AGI and adds back specific items depending on which tax benefit you're testing eligibility for — it isn't one fixed number. For expats, the most consequential add-back is the Foreign Earned Income Exclusion: even if your AGI looks like $0 because you excluded all your foreign wages, that excluded amount often gets added back for MAGI tests like Roth IRA eligibility, education credit phase-outs, and the Net Investment Income Tax threshold. This catches a lot of expats off guard, since a low AGI doesn't necessarily mean a low MAGI — see the full MAGI calculation guide for how it's tested purpose by purpose.

Expats can use the same standard or itemized deductions available to any US taxpayer — mortgage interest, state and local taxes, medical expenses above the threshold, and charitable gifts to US charities if itemizing — plus a few benefits more relevant to life abroad, like the Foreign Housing Exclusion and ordinary business expense deductions for the self-employed. The Foreign Tax Credit is often lumped in with "deductions" in casual conversation, but it's technically a credit, not a deduction — it reduces tax owed directly rather than reducing taxable income. See the full Schedule A itemized deductions guide for the complete list and whether itemizing beats the standard deduction in your case.

Yes — ordinary and necessary business expenses are deductible on Schedule C for self-employed expats exactly like they are for any US-based business owner, regardless of where the business operates. Office costs, equipment, professional services, travel for business purposes, and similar expenses reduce your net self-employment income before it's subject to tax — and that net figure is also what your income tax (potentially excludable via the FEIE) and self-employment tax are calculated from. See tax tips for self-employed expats for how this fits together with foreign income reporting.

Not if you're an employee — unreimbursed employee expenses, including work-related continuing education, were suspended under the 2017 tax law and have now been permanently eliminated, so there's no deduction route for them going forward. Self-employed expats are in a better position: education that maintains or improves skills needed in your current business is still deductible as an ordinary business expense on Schedule C, as long as it doesn't qualify you for a new trade or profession. Either way, if the education itself qualifies, education tax credits like the American Opportunity or Lifetime Learning Credit may be a better route than trying to deduct the cost directly.

Only if you're self-employed — a work permit, visa, or professional license needed to operate your business abroad is generally deductible as an ordinary business expense on Schedule C. If you're an employee, the cost falls into the same category as other unreimbursed employee expenses, which are no longer deductible under current law; your best options are getting your employer to reimburse the cost directly (reimbursements aren't taxed as income) or simply absorbing it as a nondeductible personal cost. See tax tips for self-employed expats for how permit and licensing costs fit alongside other deductible business expenses.

Generally no — day-to-day family living expenses are nondeductible personal expenses under US tax law, regardless of what country you're living in. The relief for families abroad comes through specific, narrower benefits instead: the Foreign Housing Exclusion covers your own qualifying housing costs (not general household spending), and the Child Tax Credit or Credit for Other Dependents can offset some of the cost of raising kids overseas. There's no broad deduction for "the cost of living abroad with your family" beyond those targeted provisions.
