Corporate Taxation and Legal Obligations in Türkiye in 2025: A Guide for Entrepreneurs
In 2025, Türkiye has introduced significant updates to its corporate taxation system and legal requirements for companies. For both local and international entrepreneurs, understanding these regulations is key to maintaining compliance and optimizing business performance.
1. Income Tax Rates for Sole Proprietorships
In Türkiye, income earned by sole proprietors is subject to a progressive income tax system. As of 2025, the updated income tax brackets are as follows:
| Income Bracket (TRY) | Tax Rate |
|---|---|
| 0 – 158,000 | 15% |
| 158,001 – 330,000 | 20% |
| 330,001 – 800,000 | 27% |
| 800,001 – 4,300,000 | 35% |
| 4,300,001 and above | 40% |
For example, a sole proprietorship earning a net income of TRY 420,000 would calculate tax as follows:
- TRY 158,000 × 15% = TRY 23,700
- TRY 172,000 × 20% = TRY 34,400
- TRY 90,000 × 27% = TRY 24,300
Total tax liability: TRY 82,400.
2. Corporate Tax (Kurumlar Vergisi)
Corporate entities in Türkiye are subject to a flat tax regime, with distinct rates based on industry:
- General corporate tax rate: 25%
- Financial sector rate: 30%
Also, beginning in 2025, a minimum corporate tax (“asgari kurumlar vergisi”) has been introduced. Regardless of exemptions or deductions, companies are required to pay tax on a defined minimum base. This measure aims to limit excessive corporate loss declarations and ensure consistent revenue for the government.
