Tax Treaty
A bilateral agreement between the United States and a foreign country that allocates taxing rights and provides benefits to reduce or eliminate double taxation on cross-border income.
Detailed Explanation
The US has tax treaties with roughly 70 countries. Treaty benefits include reduced withholding rates on dividends, interest, and royalties; exemption from US tax on certain pensions, social security, and student/teacher income; and tie-breaker rules to determine residency for individuals who would otherwise qualify as residents of both countries. Treaty positions claimed contrary to internal US law generally must be disclosed on Form 8833. The Saving Clause in most treaties allows the US to tax its citizens regardless of treaty residency.
Key Points
- The US has income tax treaties with roughly 70 countries to reduce double taxation.
- Benefits include reduced withholding on dividends, interest, and royalties, and residency tie-breaker rules.
- Treaty positions overriding US internal law generally must be disclosed on Form 8833.
- The Saving Clause lets the US tax its own citizens and residents as if the treaty did not exist (with exceptions).
- Treaties do not override FBAR/FATCA reporting or, in most cases, the taxation of US citizens abroad.
Practical Example
A resident of a treaty country receives US-source dividends. The default US withholding rate is 30%, but the treaty reduces it to 15%. The investor provides Form W-8BEN to the US payer to claim the lower treaty rate, cutting the withholding in half.
