An agreement between the US and another country that reduces or eliminates double taxation on specific income types, such as pensions, dividends, and student income, and sets tie-breaker rules for residency.
Treaties rarely eliminate US filing for citizens because of the saving clause, but they can change the rate on dividends and interest, exempt certain pensions, and settle which country is home for a dual resident. Claiming a treaty position requires Form 8833.
Usually not. The saving clause lets the US tax its citizens as if the treaty did not exist, with limited exceptions. The treaty changes what is taxed, not whether you file.
