Turkey Corporate Tax System
The Turkey Corporate Tax System defines tax obligations, rates, and available incentives for businesses. For businesses, understanding the corporate tax system in any country is essential to ensure compliance and to take advantage of any available benefits. In Turkey, the corporate tax system is relatively straightforward but has specific nuances that foreign businesses and investors need to be aware of. This guide will walk you through the key elements of Turkey’s corporate tax system, including tax rates, filing requirements, and available deductions.
Corporate Tax Rate in Turkey
The corporate tax rate in Turkey is currently set at 20% (The rate is 25% in law. But it’s 20% for the tax compliant taxpayers) and there are different types of rates for different sectors. However, this rate may vary depending on government fiscal policies or specific industry incentives. This tax applies to the net profit of businesses, which is calculated after deducting allowable business expenses.
Both local and foreign businesses that have operations or earn income in Turkey are subject to corporate tax. Foreign businesses are only taxed on their income derived from Turkish sources, while local businesses are taxed on their global income.

Value Added Tax (VAT)
In addition to corporate tax, companies in Turkey must also deal with Value Added Tax (VAT). VAT is charged on the sale of goods and services and is applied at different rates depending on the product or service. The standard VAT rate in Turkey is 20%, though reduced rates of 1% or 10% apply to specific items such as food, medical products, and certain real estate transactions.
Businesses must register for VAT with the Turkish tax authorities and submit VAT returns on a regular basis. Failure to comply with VAT regulations can lead to penalties, so maintaining accurate records is crucial.
Withholding Tax in Turkey
Turkey also imposes withholding taxes on certain types of income. This tax applies to dividends, interest, royalties, and payments for services provided by non-residents. The withholding tax rate varies depending on the nature of the transaction and whether there is a double taxation treaty between Turkey and the country of the recipient.
For example, dividends paid to foreign shareholders may be subject to a 15% withholding tax unless a lower rate is specified in a double taxation treaty. Withholding taxes must be reported and paid to the tax authorities, and failure to do so can result in significant penalties.
Filing Corporate Tax Returns
Businesses in Turkey are required to file corporate tax returns on an annual basis. The tax year generally follows the calendar year, and corporate tax returns must be submitted by the end of April following the relevant tax year. In addition to the annual corporate tax return, businesses must also file quarterly advance tax returns, which are due within a month after the end of each quarter.
It’s important to note that tax payments are based on self-assessment, meaning businesses are responsible for calculating and paying the correct amount of tax. Errors in tax filings can lead to fines and audits by the Turkish tax authorities.
Tax Deductions and Exemptions
Turkey offers various tax deductions and exemptions to encourage investment and support business growth. Businesses can deduct a wide range of expenses, including operating costs, employee salaries, and depreciation of assets, from their taxable income. Additionally, companies engaged in research and development (R&D) activities may qualify for further tax incentives, such as corporate tax deductions and reductions in social security premiums for R&D personnel.
Certain regions and sectors, such as technology parks and free zones, also benefit from full or partial corporate tax exemptions, making these areas attractive for businesses looking to minimize their tax burden.

Double Taxation Treaties
Turkey has signed double taxation treaties with over 80 countries to prevent businesses from being taxed on the same income in both Turkey and their home country. These treaties often provide reduced withholding tax rates on dividends, interest, and royalties, as well as clarify the rules for taxing business profits across borders.
By taking advantage of these treaties, foreign businesses can reduce their overall tax burden and avoid being taxed twice on the same income. It’s advisable to consult a tax expert familiar with international tax laws to ensure that your business fully benefits from these agreements.
Conclusion
Understanding Turkey’s corporate tax system is key to ensuring that your business remains compliant with local laws and maximizes any available tax benefits. From corporate tax rates and VAT to withholding taxes and double taxation treaties, navigating these regulations can be complex. Consulting with a knowledgeable tax advisor and keeping accurate financial records will help your business meet its tax obligations and take full advantage of deductions and incentives.
