Turkish Tax System: Tax Types and Taxpayer Obligations

Overview of the Turkish Tax System

The Turkish tax system is administered by the Turkish Revenue Administration (Gelir İdaresi Başkanlığı) and is structured into two primary categories: direct taxes and indirect taxes. Understanding these tax types is essential for individuals and businesses operating in Turkey.

Turkey applies a residency-based taxation system, meaning tax residents are liable for worldwide income, while non-residents are only taxed on Turkish-sourced income.
