U.S. persons living abroad are often entitled to substantial U.S. tax relief principally through the foreign earned income exclusion, foreign housing exclusion, and/or foreign tax credit (claimed via IRS Forms 2555 and 1116). Moreover, effective U.S. income tax rates can occasionally be negative: in principle, some U.S. persons can qualify for refundable tax credits (net cash payments from the IRS) on non-excluded income even while living outside the U.S., such as the past Making Work Pay tax credit. All other U.S. tax advantages remain available in principle, such as U.S. tax-advantaged retirement and education savings accounts. No matter where they live, U.S. persons must file all required financial reports such as U.S. FinCEN Form 114.
