Quick answer
Turkey's double tax treaties in 2026. How international businesses apply DTAs to avoid double taxation, claim withholding exemptions and reduce tax burden.
Turkey has established one of the most extensive double taxation agreement (DTA) networks in the region, with over 85 bilateral treaties in force. These agreements protect foreign investors from being taxed twice on the same income, which directly affects the after-tax return on Turkish operations. This guide explains how Turkey’s DTA network works as of 2026 and how to apply it to dividends, interest, royalties and service income.
What Are Double Taxation Agreements?
A Double Taxation Agreement (also known as a Double Tax Treaty or DTA) is a bilateral agreement between two countries that determines which country has the right to tax specific types of income. These agreements prevent the same income from being taxed in both countries, eliminating a major barrier to international trade and investment.
DTAs typically cover corporate income tax, personal income tax, dividends, interest, royalties, capital gains, and income from professional services. They establish clear rules for determining tax residency and allocating taxing rights between the contracting states.

Reduced Withholding Tax Rates Under DTAs
One of the most significant benefits of DTAs is the reduction of withholding tax rates. Turkey’s standard withholding tax rates (without a treaty) are:
-
Dividends: 15% general domestic rate for qualifying payments to non-residents from 22 December 2024
-
Interest: 0%-10% (depending on type)
-
Royalties: 20%
Under a DTA, a domestic rate may be reduced when the recipient is treaty-resident, is the beneficial owner where required, and satisfies any ownership and procedural conditions. The table below is only an orientation: the signed treaty, protocol and current domestic law must be checked for the specific payment.

How to Benefit from DTAs
To claim reduced withholding tax rates under a DTA, the following steps are typically required:
-
Tax Residency Certificate: Obtain a certificate of tax residency from your home country’s tax authority proving you are a tax resident
-
Apostille/Notarization: Have the certificate apostilled or notarized depending on the country
-
Turkish Translation: Provide a Turkish translation of the certificate
-
Submit to Revenue Administration: File the certificate with the Turkish Revenue Administration before the withholding tax is applied
It is important to submit the tax residency certificate before the income payment is made. If the certificate is not provided in time, the standard withholding rate will apply, and the overpayment must be recovered through a refund process.
Permanent Establishment (PE) Rules
DTAs define what constitutes a “Permanent Establishment” in Turkey. Under most of Turkey’s treaties (based on the OECD Model), a PE is defined as a fixed place of business through which the enterprise carries on its business. This typically includes offices, branches, factories, workshops, and construction sites lasting more than 12 months. If a foreign company is deemed to have a PE in Turkey, it becomes subject to corporate tax in Turkey on the profits attributable to that PE.
Global Minimum Tax Impact (Pillar Two - 2026)
Turkey has enacted global and domestic minimum top-up tax rules aligned with the OECD Pillar Two framework. In-scope multinational groups generally use a EUR 750 million consolidated revenue threshold and a 15% minimum effective rate. The effect of treaty relief and Turkish incentives must be modelled under the detailed group- and jurisdiction-level calculation; it is not a simple replacement for treaty rules.
Apply the Treaty to the Operating Facts
A treaty rate is only part of the analysis. Foreign enterprises should first map permanent establishment risk in Turkey and then test registration, withholding and profit-attribution consequences against the relevant treaty.

Frequently Asked Questions
How many double taxation treaties does Turkey have?
Turkey has more than 85 double taxation agreements in force, covering most of Europe, the Americas, Asia, the Middle East, Africa, and the CIS. The network includes major partners such as the United States, United Kingdom, Germany, China, and the Gulf states.
How do I claim a reduced withholding tax rate under a treaty?
You obtain a tax residency certificate from your home tax authority, have it apostilled or notarized, provide a Turkish translation, and file it with the Turkish Revenue Administration. The certificate must reach the payer before the income is paid; otherwise the full domestic rate is withheld and you have to reclaim the difference later through tax services in Turkey or your home-country procedures.
What withholding rates apply without a treaty?
The general domestic dividend withholding rate for qualifying payments to non-residents is 15% from 22 December 2024. Interest and royalty rates depend on the legal character of the payment and recipient. A treaty may reduce the domestic rate, but the result depends on the specific treaty, beneficial-ownership condition, ownership percentage and supporting residence documentation. Check the Revenue Administration’s current withholding table before payment.
When does a foreign company create a permanent establishment in Turkey?
Most of Turkey’s treaties follow the OECD model, under which a permanent establishment is a fixed place of business such as an office, branch, or factory, or a construction site lasting more than 12 months. Once a permanent establishment exists, Turkey can tax the profits attributable to it.
Does the global minimum tax change how treaties work?
Pillar Two does not replace treaty relief. For an in-scope group, treaty outcomes and local incentives feed into a separate jurisdiction-level effective-tax calculation under the minimum-tax rules. A top-up can arise, but it should not be stated as an automatic charge on every Turkish entity below 15%.
Can a treaty completely eliminate Turkish tax on my income?
Rarely in full. Treaties allocate taxing rights and reduce withholding rates, but they seldom remove Turkish tax entirely on Turkey-sourced income or on profits attributable to a permanent establishment. The practical goal is to avoid paying tax twice and to apply the lowest rate the treaty allows.
