What Is Withholding Tax in Türkiye?

Withholding tax in Türkiye refers to the tax deducted at source by the payer on certain types of income and remitted directly to the Turkish Revenue Administration. The recipient receives the net amount after tax deduction, while the withholding party bears the legal responsibility for correct calculation and timely payment.

Withholding tax applies to both resident and non-resident taxpayers and covers a wide range of income categories, including employment income, professional service fees, dividends, interest, royalties, rental income, and certain cross-border payments.

Failure to comply with withholding tax obligations can result in substantial tax penalties, late payment interest, and potential tax audits.

Key Withholding Tax Types in Türkiye (2026 Overview)

Employment Income Withholding Tax

Employers in Türkiye are required to withhold income tax and social security contributions from employee salaries. Progressive tax rates apply, and monthly payroll filings must be submitted accurately and on time.

Professional Service Fees

Payments made to freelancers, consultants, lawyers, accountants, and other professionals are subject to withholding tax, even when services are rendered partially or fully outside Türkiye, depending on the source of income.

Dividends

Dividend distributions by Turkish companies are subject to withholding tax, typically at a standard rate, though reduced rates may apply under double taxation treaties.

Interest and Royalties

Interest payments on loans and royalties for intellectual property rights are also subject to withholding tax, with rates varying based on the nature of the income and the residency of the recipient.

Rental Income

Lease payments for real estate or movable assets may trigger withholding tax obligations for the tenant or lessee.

Withholding Tax Rates and Treaty Benefits

Türkiye has an extensive network of double taxation avoidance agreements (DTAs) with more than 90 countries. These treaties often provide reduced withholding tax rates or exemptions for dividends, interest, royalties, and service income.

However, treaty benefits are not automatic. Businesses must:

• Correctly identify tax residency
• Obtain valid certificates of residence
• Apply appropriate treaty articles
• Maintain robust documentation

Our role as an experienced Turkish accounting firm is to ensure treaty benefits are applied correctly while minimizing audit risks.

Who Is Responsible for Withholding Tax Compliance?

Under Turkish tax law, the withholding agent—usually the payer—is fully responsible for:

• Determining whether withholding tax applies
• Applying the correct tax rate
• Filing monthly withholding tax returns
• Remitting taxes within statutory deadlines

This applies to:

• Turkish companies
• Branches of foreign companies
• Employers
• Public institutions
• Certain individuals making taxable payments

Working with a qualified Istanbul accountant is essential to avoid misinterpretation of withholding obligations.

Common Withholding Tax Risks in Türkiye

Many businesses face withholding tax exposure due to:

• Incorrect classification of payments
• Misapplication of treaty rates
• Late or inaccurate filings
• Failure to withhold tax on cross-border services
• Incomplete supporting documentation

These risks often surface during tax inspections, leading to retrospective tax assessments and penalties. Professional withholding tax services significantly reduce these exposures.
