Overview of Personal Income Tax in Turkey
Turkey’s personal income tax system applies to both residents and non-residents, with taxation obligations determined by residency status. Individuals who are tax residents of Turkey are taxed on their global income, while non-residents are only taxed on their Turkey-sourced income.
Residency for Tax Purposes
- Resident Taxpayers: Individuals who reside in Turkey for more than six months within a calendar year are considered tax residents. Resident taxpayers are subject to income tax on their worldwide income.
- Non-Resident Taxpayers: Non-residents are only taxed on income derived from Turkish sources, such as local employment, rental income, or investments in Turkey.
Understanding one’s residency status is crucial as it determines the scope of income to be reported in the Turkish personal income tax declaration.
Types of Income Subject to Personal Income Tax
Personal income tax in Turkey applies to a range of income types. Foreign investors should understand the categories of income subject to taxation to ensure accurate reporting.
Taxable Income Categories
- Employment Income: Wages, salaries, and benefits from employment within Turkey.
- Rental Income: Income earned from renting property located in Turkey.
- Business Profits: Profits derived from business activities conducted in Turkey.
- Capital Gains: Gains from the sale of assets such as property, shares, or investments in Turkey.
- Investment Income: Interest, dividends, and other earnings from financial assets and investments held in Turkey.

Each category has specific rules for deductions and exemptions, which are crucial for minimizing tax liabilities. For foreign investors, understanding these classifications is essential for accurate reporting and taking advantage of allowable deductions.

Income Tax Rates in Turkey
Turkey’s income tax rates are progressive, meaning they increase with higher income brackets. For 2024, the income tax rates range from 15% to 40%, and the tax brackets are updated annually.

Foreign investors should consider how their total taxable income in Turkey aligns with these brackets to effectively manage tax planning.

Deductions and Exemptions Available to Taxpayers
Turkey offers several deductions and exemptions that can help taxpayers reduce their taxable income. Foreign investors should understand which deductions apply to their income sources to optimize their tax liabilities.

Tax Treaties and Foreign Tax Credits
Turkey has tax treaties with several countries to prevent double taxation and make it easier for foreign investors to manage tax obligations across borders. These treaties allow for foreign tax credits, helping investors offset taxes paid in other countries.
How Tax Treaties Benefit Foreign Investors
- Double Taxation Avoidance: Prevents taxpayers from being taxed on the same income in both Turkey and their home country.
- Tax Credits: Provides credits for foreign taxes paid, which can be deducted from the Turkish tax liability.
