Double taxation treaties are bilateral agreements between two countries that determine which country has the right to tax specific types of income when a taxpayer is connected to both jurisdictions. For foreign investors and multinational companies operating in Turkey, these treaties are among the most important tools for managing cross-border tax costs. Without treaty protection, the same income can be taxed in full by both Turkey and the investor's home country, effectively doubling the tax burden.
Turkey has built one of the most extensive double taxation treaty networks among emerging market economies, with over 80 agreements in force covering virtually all major trading partners and investment source countries. This guide provides a complete overview of Turkey's treaty network, the mechanics of claiming treaty benefits, withholding rate reductions available under key treaties, permanent establishment rules, and practical guidance for structuring cross-border transactions to take full advantage of treaty protections.
How Double Taxation Treaties Work
Double taxation treaties allocate taxing rights between two countries. They do not create new tax obligations; they limit the extent to which each country can tax income that has a connection to both jurisdictions. Treaties achieve this through several mechanisms:
Residence rules. The treaty defines which country a person or company is considered resident in for tax purposes. If a company could be considered resident in both countries, the treaty provides tie-breaker rules (typically based on the place of effective management).
Income allocation rules. Different articles of the treaty cover different types of income (business profits, dividends, interest, royalties, capital gains, employment income, etc.) and specify which country may tax each type.
Withholding tax reductions. Treaties typically reduce the withholding tax rates that the source country (where the income originates) can impose on cross-border payments such as dividends, interest, and royalties.
Elimination of double taxation. The treaty requires the country of residence to provide relief from double taxation, usually through either a credit method (allowing the taxpayer to credit foreign taxes against domestic tax) or an exemption method (exempting foreign-source income from domestic tax).
Mutual agreement procedure. If a taxpayer believes they are being taxed in violation of the treaty, they can request that the competent authorities of both countries consult to resolve the issue.
Turkey's treaties are based primarily on the OECD Model Tax Convention, which makes them broadly similar in structure and terminology. However, our analysts note that each treaty contains unique provisions, rate schedules, and definitions that can differ materially from the model. Relying on general treaty knowledge without consulting the specific text of the relevant treaty is a common and potentially costly mistake.

The rates shown above represent the maximum withholding rate that the source country may impose under the treaty. The actual rate applied may be lower if the source country's domestic rate is already below the treaty rate, since treaties can only reduce, not increase, tax obligations. Our analysts recommend always comparing the treaty rate against Turkey's domestic withholding rate to determine which applies.
Key Treaty Relationships for Foreign Investors
Turkey-United States Treaty
The Turkey-US treaty, signed in 1996 and effective since 1998, is particularly important given the volume of US investment in Turkey. Key provisions include:
- Dividends: 15% withholding for portfolio holdings; 5% for holdings of 10% or more of voting shares
- Interest: 10% withholding (with certain exemptions for government bonds and qualifying financial institutions)
- Royalties: 10% withholding
- Capital gains: Generally taxable only in the country of residence, with exceptions for real property and business assets of a permanent establishment
- Permanent establishment threshold: Includes a construction PE clause with a 12-month threshold
The US treaty is one of the few Turkey treaties that uses a 10% holding threshold (rather than 25%) for the reduced dividend rate, making it easier for US investors to qualify for the lower 5% rate.
Turkey-United Kingdom Treaty
The Turkey-UK treaty provides:
- Dividends: 15% portfolio; 5% for holdings of 25% or more
- Interest: 10% withholding
- Royalties: 10% withholding
- Services PE: The treaty contains provisions addressing service-based permanent establishments
Following Brexit, the treaty continues to apply to the UK's relationships with Turkey independently of any EU framework. UK investors benefit from the relatively low withholding rates across all categories.
Turkey-Germany Treaty
Germany is one of Turkey's largest trading partners, making this treaty highly relevant:
- Dividends: 15% portfolio; 5% for holdings of 25% or more
- Interest: 10% withholding
- Royalties: 10% withholding
- Real property: Income from Turkish real property is taxable in Turkey
Turkey-UAE Treaty
The Turkey-UAE treaty has gained importance as bilateral investment flows have increased significantly:
- Dividends: 10% portfolio; 5% for holdings of 25% or more
- Interest: 10% withholding
- Royalties: 10% withholding
- Capital gains: The treaty provides favorable treatment for capital gains on shares
The UAE treaty is frequently used in international tax structuring due to the UAE's territorial tax system. However, our analysts caution that Turkey's anti-avoidance provisions, including the Controlled Foreign Corporation (CFC) rules and the general anti-avoidance rule, apply to structures that lack economic substance. Routing investments through the UAE purely for treaty benefits without genuine business activity in the UAE may be challenged by the Turkish Revenue Administration.
Permanent Establishment Rules
The concept of permanent establishment (PE) is central to how treaties allocate the right to tax business profits. Under Turkey's treaties, a foreign company is generally only subject to Turkish corporate tax on its business profits if it has a permanent establishment in Turkey. Without a PE, business profits are taxable only in the company's country of residence.
A permanent establishment typically includes:
- A fixed place of business (office, branch, factory, workshop, mine, construction site)
- A dependent agent who habitually exercises authority to conclude contracts on behalf of the foreign company
- A construction or installation project that lasts longer than the treaty-specified threshold (typically 6 to 12 months depending on the treaty)
- Service activities performed in Turkey for more than a specified number of days within any 12-month period (typically 183 days, though some treaties use shorter periods)
Activities That Do Not Create a PE
Most Turkey treaties include a list of activities that are considered preparatory or auxiliary and do not create a PE, including:
- Storage, display, or delivery of goods belonging to the enterprise
- Maintenance of stock for processing by another enterprise
- Purchasing goods or collecting information
- Advertising, providing information, or scientific research that is preparatory or auxiliary
Construction PE Thresholds
Construction PE thresholds vary across Turkey's treaties. The following table shows the threshold for selected key treaties:
| Treaty Partner | Construction PE Threshold |
|---|---|
| United States | 12 months |
| United Kingdom | 12 months |
| Germany | 12 months |
| France | 12 months |
| Netherlands | 12 months |
| UAE | 9 months |
| Russia | 18 months |
| China | 12 months |
| Japan | 12 months |
| South Korea | 12 months |
| Saudi Arabia | 6 months |
| Qatar | 6 months |
The PE threshold determines when a construction or installation project gives rise to a taxable presence in Turkey. Our analysts note that Turkey's domestic tax law defines a broader concept of PE than most treaties, so the treaty definition generally provides a higher threshold and more protection for foreign companies. Always check the specific treaty rather than relying on Turkey's domestic PE definition when a treaty applies.
How to Claim Treaty Benefits in Turkey
Claiming double taxation treaty benefits in Turkey requires following a specific administrative process. The steps differ depending on whether you are seeking reduced withholding at source or claiming a tax credit or exemption on your annual return.
Claiming Reduced Withholding Tax at Source
Obtain a certificate of tax residence from the tax authority in your home country. This certificate must confirm that you are a resident of the treaty partner country for tax purposes during the relevant period.
Apostille the certificate under the Hague Apostille Convention (if both countries are signatories) or have it certified by the Turkish consulate in your country.
Have the certificate translated into Turkish by a sworn translator (yeminli tercuman) in Turkey.
Submit the apostilled, translated certificate to the Turkish withholding agent (the company making the payment) before the payment is made.
The withholding agent applies the treaty rate instead of the domestic rate and reports the treaty rate on its withholding tax return.
If the withholding agent is not confident in applying the treaty rate (which happens frequently), they may withhold at the domestic rate, and the non-resident recipient must then apply for a refund of the excess withholding.
Claiming Relief Through the Annual Tax Return
For Turkish resident companies receiving income from treaty countries, relief from double taxation is claimed on the annual corporate tax return:
Determine the method of relief specified in the relevant treaty (credit method or exemption method).
For the credit method: Include the foreign income in your Turkish taxable income, calculate the Turkish tax on total income, then credit the foreign tax paid against the Turkish tax liability. The credit is limited to the amount of Turkish tax attributable to the foreign income.
For the exemption method: Exclude the qualifying foreign income from your Turkish taxable income.
Maintain documentation including foreign tax payment receipts, foreign tax returns, and the relevant treaty articles to support the claim.
Statute of Limitations for Treaty Refund Claims
Non-residents who had excessive withholding tax deducted in Turkey may file a refund claim within five years from the end of the calendar year in which the withholding occurred. The refund application is filed with the tax office where the withholding agent is registered.
Controlled Foreign Corporation (CFC) Rules
Turkey's CFC rules are relevant to the treaty analysis because they can override treaty benefits in certain situations. Under the CFC rules, a Turkish resident company must include in its taxable income the undistributed profits of a foreign subsidiary if:
- The Turkish company owns at least 50% of the foreign subsidiary (directly or indirectly)
- More than 25% of the foreign subsidiary's gross income consists of passive income (dividends, interest, royalties, rental income, capital gains)
- The foreign subsidiary's effective tax rate is less than 10%
- The foreign subsidiary's gross income exceeds a specified threshold
These rules are designed to prevent Turkish companies from deferring tax by accumulating passive income in low-tax jurisdictions. The CFC rules apply regardless of whether a double taxation treaty exists between Turkey and the subsidiary's jurisdiction.
Mutual Agreement Procedure
If a taxpayer believes that the actions of one or both treaty countries result in taxation that is not in accordance with the treaty, they may request a mutual agreement procedure (MAP). The request must be filed with the competent authority of the taxpayer's country of residence within the time limit specified in the treaty (typically three years from the first notification of the disputed taxation).
The competent authorities of both countries then consult to resolve the issue. While the MAP process does not guarantee a resolution, Turkey has generally been cooperative in MAP cases and has resolved a significant proportion of requests.
Turkey has also signed the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI), which modifies the application of many of Turkey's bilateral treaties with respect to anti-avoidance provisions, permanent establishment definitions, and dispute resolution.
Practical Considerations for Treaty Planning
Always verify the treaty is in force. Turkey has signed some treaties that have not yet been ratified or have not entered into force. Only treaties that have been published in Turkey's Official Gazette are legally effective.
Check for most-favored-nation clauses. Some of Turkey's treaties contain most-favored-nation (MFN) clauses that automatically extend more favorable rates negotiated in subsequent treaties. This is not common but occurs in certain Turkey treaties and can provide unexpected benefits.
Consider the entire holding structure. Treaty benefits depend on the residence of the immediate recipient of the income. If your corporate structure involves intermediate holding companies, the applicable treaty is the one between Turkey and the country where the intermediate company is resident, not the country of the ultimate parent.
Maintain substance in treaty jurisdictions. Turkey's tax authorities increasingly scrutinize treaty claims where the recipient entity lacks economic substance in the treaty country. Entities that exist solely to benefit from a treaty, without employees, offices, or genuine business activities, may be denied treaty benefits under domestic anti-avoidance rules or the principal purpose test introduced by the MLI.

Conclusion
Turkey's extensive double taxation treaty network provides substantial relief for foreign investors and multinational companies operating across borders. With over 80 treaties in force, covering virtually all major economies, Turkish-based companies and foreign investors in Turkey have access to reduced withholding rates, clear PE definitions, and established dispute resolution mechanisms.
The practical value of these treaties depends entirely on proper implementation: obtaining timely residence certificates, maintaining proper documentation, and structuring transactions with genuine economic substance. Companies that invest in understanding and correctly applying the relevant treaty provisions will find that the cross-border tax cost of operating in Turkey is significantly lower than the domestic rates might suggest.
Our analysts recommend engaging a tax advisor with specific experience in Turkish treaty claims, as the administrative process for obtaining reduced withholding and filing refund claims involves specific documentation requirements that are strictly enforced by the Turkish Revenue Administration.
Frequently Asked Questions
How many double taxation treaties does Turkey have?
Turkey has signed double taxation agreements with over 80 countries as of 2026. These treaties cover all major trading partners including the United States, United Kingdom, Germany, France, the Netherlands, Japan, South Korea, China, Russia, and the UAE. The treaties are based primarily on the OECD Model Tax Convention, though individual treaties may contain variations in withholding tax rates, permanent establishment definitions, and specific provisions for certain types of income.
How do I claim treaty benefits in Turkey?
To claim double taxation treaty benefits in Turkey, the non-resident taxpayer must obtain a certificate of tax residence from their home country's tax authority, have this document apostilled and translated into Turkish by a sworn translator, and submit it to the Turkish tax office or the Turkish withholding agent before the relevant payment is made. The withholding agent can then apply the reduced treaty rate instead of the standard domestic rate. If the reduced rate was not applied at the time of payment, the non-resident can file a refund application with the Turkish Revenue Administration within the applicable statute of limitations.
Does Turkey have a double taxation treaty with the United States?
Yes, Turkey and the United States signed a double taxation treaty in 1996, which entered into force in 1998. The treaty covers income tax and includes reduced withholding rates of 15% on dividends (5% for substantial holdings of 10% or more), 10% on interest, and 10% on royalties. The treaty also contains provisions on permanent establishment, capital gains, independent and dependent personal services, and a mutual agreement procedure for resolving disputes.
