Double tax treaty

Double tax treaties (DTTs) divide the right to tax each income type between residence and source states, cap withholding rates, and provide the tiebreaker cascade when both countries claim you as resident. Türkiye’s network is broad; the US–Türkiye treaty dates to 1996. Treaties can reduce foreign withholding on your portfolio — which, under Law 7582’s no-credit rule, is exactly where the savings live.
