US filing basics for Americans in Hong Kong

Living in Hong Kong does not terminate your U.S. federal income tax obligations. U.S. citizens, green-card holders, and certain long-term residents are taxed on worldwide income on a citizenship or residency basis, regardless of where the income is earned or where you reside. You generally must file Form 1040 (or 1040-SR) when gross income exceeds the annual IRS filing threshold, typically $15,000 to $30,000 or more depending on filing status, age, and dependency for recent tax years (exact amounts published in IRS Rev. Proc. documents and inflation-adjusted). Even if no tax is ultimately due after credits and exclusions, filing is usually required to claim benefits such as the Foreign Earned Income Exclusion (FEIE) under IRC §911 (up to $130,000 for tax year 2025 per IRS Rev. Proc. 2024-40) or the Foreign Tax Credit (FTC) for taxes paid to Hong Kong authorities.
