Tax treaty

A tax treaty is an agreement between the United States and another country that allocates taxing rights and reduces double taxation, and treaty benefits claimed on a return are disclosed on Form 8833.

Treaties can reduce withholding, define residency tie-breakers, and exempt certain pensions and student income. A saving clause generally preserves U.S. taxation of citizens regardless of the treaty.

Why it matters: treaties help less than expats expect because of the saving clause, but the residency tie-breaker can decide which country’s rules apply. See Form 8833.
