What is the corporate tax rate in Turkey for 2025?

Quick Answer

Turkey's corporate income tax rate (Kurumlar Vergisi) is 25% for the 2025 tax year. All Limited Sirket and Anonim Sirket companies pay this flat rate on taxable profit. Quarterly advance payments (Gecici Vergi) are made at the same 25% rate throughout the year and credited against the annual liability.

Detailed Explanation

Turkey's corporate tax rate has changed several times in recent years, making it important to confirm the rate for each specific tax year.

Current rate: 25% (2025) For the tax year 2025 (1 January to 31 December 2025), the Kurumlar Vergisi rate is 25%. This applies to all capital companies β€” Limited Sirket (Ltd. Sti.) and Anonim Sirket (A.S.) β€” as well as cooperatives and other entities subject to corporate tax.

Rate history The corporate tax rate has been: - 20%: 2006 through 2020 - 25%: 2021 and 2022 (temporary increase) - 23%: 2023 - 25%: 2024 onwards

This volatility makes it essential to check the official GIB published rates each year rather than relying on memory or older sources.

How the tax is calculated Taxable profit is calculated by taking the commercial accounting profit (prepared under Turkish Accounting Standards) and making statutory adjustments: - Adding back non-deductible expenses (Kanunen Kabul Edilmeyen Giderler β€” KKEG): fines and penalties, entertainment above 0.5% of net sales, disallowed interest under thin-cap or FGK rules, personal expenses - Deducting qualifying items: investment incentive allowances, R&D super-deductions (150% for qualifying spend), prior year loss carry-forwards

The resulting taxable profit is multiplied by 25% to arrive at the Kurumlar Vergisi liability.

Gecici Vergi β€” quarterly advance payments Rather than paying the full annual corporate tax in April, companies make quarterly advance payments (Gecici Vergi) throughout the year at the same 25% rate. These are calculated on cumulative quarterly commercial profit: - Q1 (January-March): paid by 17 May - Q2 (April-June): paid by 17 August - Q3 (July-September): paid by 17 November - Q4 (October-December): paid by 17 February of the following year

All four quarterly payments are credited against the final annual Kurumlar Vergisi declared in April. Any shortfall is paid in April; any overpayment is refunded or credited against other taxes.

Reduced corporate tax rates Several mechanisms reduce the effective corporate tax rate below 25%:

  • IPO incentive: Companies completing an initial public offering and listing on Borsa Istanbul receive a 2-percentage-point reduction in the corporate tax rate (23% instead of 25%) for 5 years.
  • Investment Incentive Certificates: Companies with approved investment projects can benefit from corporate tax reductions ranging from 15% to 90% of tax depending on the investment region (Regions 1-6, with 6 being the most underdeveloped, offering the highest incentives) and investment size. Under a Strategic Investment Certificate, rates can approach 0% on income from the incentivised investment.
  • Technology Development Zone (Technopark) companies: Income from software development and R&D activities conducted within a licensed Teknoloji Gelistirme Bolgesi is fully exempt from Kurumlar Vergisi.
  • Free Zone companies: Companies operating in Turkish Free Zones (Serbest Ticaret Bolgesi) with export-oriented manufacturing can benefit from Kurumlar Vergisi exemption on manufacturing profits.

Comparison with neighbouring countries At 25%, Turkey's corporate tax rate is above the EU average (~21%) and higher than Ireland (12.5%), UAE (9% for SMEs), or Bulgaria (10%). It is comparable to Germany (approximately 29-33% combined) and slightly above the UK (25% main rate). The main advantage Turkey offers over these comparators is its generous investment incentive system, which can substantially reduce the effective rate for qualifying businesses.

Dividend withholding after corporate tax Once a Turkish company has paid Kurumlar Vergisi on its profits and distributes dividends to individual Turkish shareholders, an additional 15% Stopaj Vergisi is withheld on the dividend. The economic double taxation on profits extracted as dividends can therefore be significant: 25% at company level, then 15% on the remaining 75%, resulting in an effective combined rate of approximately 36.25% before the shareholder receives cash.

Real-World Examples

Standard Istanbul Limited Sirketi

An Istanbul software company earns TRY 3,000,000 taxable profit in 2025. Kurumlar Vergisi: TRY 3,000,000 Γ— 25% = TRY 750,000. After four quarterly Gecici Vergi payments of TRY 187,500 each, the April balance due is zero.

Technopark-resident company

A software company in ITU Technopark earns TRY 5,000,000 from software licences. The entire software income is exempt from Kurumlar Vergisi under Technology Development Zone Law β€” corporate tax on this income is TRY 0.

Company with investment incentive certificate

A manufacturer in a Region 5 province (Hakkari, Sirnak) with a large-scale investment certificate benefits from 90% corporate tax reduction β€” effective KV rate of 2.5% (10% of 25%) on incentivised investment income.

Common Mistakes to Avoid

  • Using the 20% rate that applied before 2021 β€” the rate is now 25% and has been since 2024
  • Forgetting to calculate non-deductible expenses (KKEG) β€” filing based on accounting profit without KKEG adjustments understates taxable profit
  • Not utilising R&D super-deductions for qualifying technology companies β€” 150% deduction is significantly underused by eligible businesses
  • Assuming the annual return is the only tax payment β€” quarterly Gecici Vergi payments are also mandatory and late payment attracts interest

Frequently Asked Questions

Is Turkey's 25% corporate tax rate final, or are there surcharges?

Turkey's 25% Kurumlar Vergisi is the only corporate income tax β€” unlike Germany, there is no separate municipal trade tax or solidarity surcharge added on top. The 25% rate is effectively the total corporate income tax burden at the company level, before dividend withholding.

Do small companies pay a lower corporate tax rate?

No. Turkey does not have a small profits rate or an SME corporate tax reduction. The 25% flat rate applies to all taxable profits regardless of company size. The main relief for smaller businesses is the investment incentive system and R&D deductions, not a reduced rate.

When is the Kurumlar Vergisi return due?

The annual Kurumlar Vergisi Beyannamesi is due by 30 April of the year following the tax year. For 2025 income, the return is due 30 April 2026 with full payment of any balance on the same date.

Practical Tips

  • Check the GIB website at the start of each tax year to confirm the applicable rate β€” it has changed 3 times in 5 years
  • Model your R&D expenses carefully: the 150% super-deduction for certified R&D can reduce taxable profit by more than actual cash spend
  • For fast-growing companies, consider whether a Technopark location would eliminate corporate tax on software income entirely β€” this is legal and widely used
