Turkey's Corporate Income Tax (CIT)
In Turkey, the standard corporate income tax (CIT) rate is 25% for companies (other than those in the financial sector), with financial sector companies subject to a rate of 30%. Resident entities are taxed on worldwide income; non-resident entities are taxed only on Turkish-sourced income. A domestic minimum CIT rule took effect on 1 January 2025, requiring that CIT payable may not be less than 10% of taxable income before certain exemptions and deductions. Turkey has implemented the OECD Pillar Two global minimum tax framework: the Income Inclusion Rule (IIR) applies for tax years from 1 January 2024; the Undertaxed Profits Rule (UTPR) applies for tax years from 1 January 2025; a 15% Qualifying Domestic Minimum Top-Up Tax (QDMTT) applies for tax years from 1 January 2024. These rules apply to multinational groups with consolidated turnover of EUR 750 million or more. A top-up tax is due when the effective tax rate in a jurisdiction falls below 15%. CIT returns are due on the 30th day of the fourth month following the fiscal year end; advance tax payments are made quarterly by the 17th of the second month of each quarter. There are no provincial or municipal income taxes on corporations in Turkey.
