Understanding corporate tax obligations is one of the most critical steps for any foreign company operating in Turkey. The Turkish tax system has undergone significant changes in recent years, with the corporate tax rate now set at 25% for 2026, along with new minimum tax rules and updated incentive programs. This comprehensive guide covers everything foreign businesses need to know about corporate taxation in Turkey for 2026.
Corporate Tax Rate in Turkey 2026
Turkey’s standard corporate tax rate for 2026 is 25%, applying to the worldwide income of resident companies and the Turkey-sourced income of non-resident companies. This rate was increased from the previous 20% as part of broader fiscal reforms.
Key rate variations for 2026:
-
Standard Rate: 25% for all corporate taxpayers
-
Financial Institutions: 30% for banks, insurance companies, and financial institutions
-
Export Income: 20% reduced rate on profits from export activities
Turkey has signed double taxation agreements with over 85 countries, including the United States, United Kingdom, Germany, France, and most EU member states. These treaties help prevent the same income from being taxed in two jurisdictions and often provide reduced withholding tax rates on dividends, interest, and royalties.
New: Domestic Minimum Corporate Tax (2026)
Starting from 2026, Turkey has implemented a domestic minimum corporate tax of 10%. This rule requires all corporate taxpayers to pay at least 10% of their adjusted corporate income, even if standard tax calculations (after incentives and deductions) yield a lower amount. This applies broadly to all Turkish corporate taxpayers, including foreign-owned subsidiaries and branches. Newly established companies are exempt from this minimum tax for their first three fiscal periods.
Global Minimum Tax - Pillar Two (OECD)
In line with the OECD’s Global Anti-Base Erosion (GloBE) framework, Turkey now applies a 15% effective minimum tax rate for large multinational enterprise groups with annual consolidated revenues exceeding €750 million. This means that if a foreign subsidiary’s effective tax rate in Turkey falls below 15% due to local incentives, the difference will be topped up. The calculations for this are based on IFRS/UFRS standards, superseding the Turkish Tax Procedure Law (VUK) for these specific calculations.
Tax Incentives for Foreign Investors
Despite the rate increase, Turkey continues to actively encourage foreign investment through robust incentive programs, including the new HIT-30 (High Tech Turkiye) program - a $30 billion initiative targeting electric vehicles, batteries, chips, solar and wind energy, and R&D:
-
Regional Investment Incentives: Reduced corporate tax rates in Priority Development Regions, employer social security contribution support, land allocation, and machinery support grants
-
Technology Development Zones (Teknokent): Income from R&D and software development activities is exempt from corporate tax and income tax until December 31, 2028
-
Free Trade Zones: Manufacturing companies operating in free trade zones enjoy corporate tax exemptions on export-related income
-
Strategic Investment Incentives: For investments exceeding certain thresholds in strategic sectors, additional benefits including VAT exemptions and customs duty exemptions
-
Machine Support (New): Direct cash grants for high-unit-price machinery and equipment purchases
Tax Filing and Compliance Requirements
Corporate tax returns in Turkey must be filed annually by the end of April following the fiscal year. The fiscal year typically aligns with the calendar year (January 1 to December 31).

Annual Corporate Tax Return: By end of April (e.g., April 30, 2026 for FY 2025)

Value Added Tax (VAT) in Turkey 2026
Turkey applies three VAT rates: 1%, 10%, and 20%. Most goods and services fall under the standard 20% rate. The 10% rate covers textiles, clothing, furniture, and certain food/beverage services. The 1% rate applies to essential foodstuffs like bread and legumes. Exported goods and services are zero-rated. For 2026, the VAT refund claim minimum has been increased to TRY 164,000.
Transfer Pricing Rules
Turkey follows OECD Transfer Pricing Guidelines. Companies conducting transactions with related parties must document that these transactions are at arm’s length prices; see our transfer pricing in Turkey guide for documentation requirements. Required documentation includes an annual transfer pricing report and, for larger groups, Country-by-Country Reporting (CbCR). Failure to maintain proper documentation can result in tax adjustments and penalties.
Withholding Taxes 2026
Turkey applies withholding taxes on various payments made to non-residents:
-
Dividends: 10% (may be reduced under tax treaties)
-
Interest: 0% to 10% depending on type and recipient
-
Royalties: 20% (may be reduced under tax treaties)
-
Service Fees: 20% for services rendered in Turkey
Frequently Asked Questions
What is the corporate tax rate in Turkey for 2026?
The standard corporate tax rate is 25%. Banks, insurance companies, and other financial institutions pay 30%, while profits from qualifying export activities benefit from a reduced 20% rate. Resident companies are taxed on their worldwide income, and non-resident companies only on income sourced in Turkey.
How does the new domestic minimum corporate tax work?
From 2026, every corporate taxpayer must pay at least 10% of adjusted corporate income, even when incentives and deductions would otherwise push the liability lower. The rule covers foreign-owned subsidiaries and branches, but newly established companies are exempt for their first three fiscal periods.
Do foreign-owned companies pay the same corporate tax as Turkish companies?
Yes. A Turkish subsidiary or branch is taxed under the same rules and at the same 25% rate as a locally owned company. The practical differences lie in treaty relief, withholding tax on profit repatriation, and transfer pricing obligations on cross-border transactions.
When is the corporate tax return due in Turkey?
The annual return is filed by the end of April following the fiscal year, so a 2025 return is due by 30 April 2026 for companies that use the calendar year. Advance corporate tax is also calculated and paid on a quarterly basis during the year.
Does Turkey apply the OECD global minimum tax?
Yes. For multinational groups with consolidated annual revenue above EUR 750 million, Turkey applies a 15% effective minimum tax in line with Pillar Two. If local incentives bring the effective rate below 15%, the shortfall is collected as a top-up calculated on IFRS-based figures rather than under the Tax Procedure Law.
Can foreign investors still reduce their tax bill through incentives?
They can. Technology Development Zones, free trade zones, regional investment incentives, and the HIT-30 high-tech program all remain available. The key change is that the 10% domestic minimum tax now sets a floor, so incentives should be modelled against that floor rather than assumed to remove the liability entirely.
