Could an income tax treaty change how a U.S.-source payment is taxed or withheld? Choose your country of tax residence and the type of income or activity. The explorer points you to the treaty path, IRS materials and forms that may be relevant.
Treaty benefits are not automatic. Eligibility can depend on treaty residence, the exact article, income type, time limits, documentation, saving-clause language and the facts for the year.

Why the explorer does not guess a treaty rate
Treaty rates and exemptions vary by country and income category, and some provisions have narrow conditions. The tool therefore emphasizes the treaty source and the documentation path instead of silently presenting a hard-coded rate that could become stale.
Federal treaty treatment and state tax are separate
A federal treaty position does not automatically settle a state tax question. If you lived or worked in a U.S. state, use the state map after the treaty review and check that state’s current instructions.
