Türkiye’s Double Taxation Avoidance Agreements: The 2026 Outlook

Türkiye has signed more than 60 Double Taxation Avoidance Agreements (DTAAs), significantly minimizing the tax burden for international investors. These agreements create a more predictable tax environment and reduce the risk of being taxed twice on the same income. For official references and the full list of agreements, see the Revenue Administration of Türkiye (GİB) and OECD Tax Treaties Database.

Türkiye’s Current Treaty Network and Status

Türkiye’s network of effective DTAAs covers major economies including Germany, France, the United States, the Netherlands, the United Kingdom, Japan, and China. This extensive network ensures that Turkish and foreign investors benefit from reduced withholding tax rates and greater investment certainty.

The agreement process continues to expand:

• 11 countries: treaties currently awaiting the approval of the Grand National Assembly of Türkiye (TBMM)
• 6 countries (Austria, Bosnia and Herzegovina, the Philippines, South Africa, Canada, Malta): initialed and ready for signature
• 14 countries: negotiations are ongoing

Allocation of Taxing Rights: Practical Implications for Investors

DTAAs allocate taxing rights between countries based on the source and type of income. This mechanism is essential for cross-border entrepreneurs conducting tax planning and structuring their investments efficiently.

Türkiye applies the credit method for the elimination of double taxation. Under this approach, foreign taxes paid can be deducted from domestic tax liabilities. In contrast, countries such as the Netherlands use the exemption method. This difference can create either tax planning opportunities or challenges depending on the investment structure and income type.

Strategic Aspect: The Netherlands Channel Effect

The Türkiye–Netherlands DTAA stands out due to its exemption method, while most of Türkiye’s other treaties apply the credit method. This variation can significantly influence the tax outcomes of investments routed through the Netherlands. For example, dividend income that would otherwise be eligible for participation exemption in direct investments may lead to different results when channeled through the Netherlands.

Exchange of Information and Tax Compliance

DTAAs include information exchange provisions that enable both countries to combat tax evasion and avoidance more effectively. In addition, cooperation clauses regarding tax collection strengthen enforcement mechanisms. For international entrepreneurs, this means greater compliance obligations and the need for accurate documentation under the OECD Exchange of Information standards.

Alignment with the OECD Multilateral Instrument

Through participation in the OECD’s Multilateral Convention to Implement Tax Treaty Related Measures (MLI), Türkiye has updated its bilateral agreements, particularly those concerning capital gains taxation. Under the revised provisions, capital gains arising from the sale of shares in real estate-rich companies are taxable in the country where the property is located. This enhances the source country’s taxing rights and impacts foreign real estate investment strategies in Türkiye.

Operational Insights for International Entrepreneurs

• treaty selection is crucial: the choice of both the investment destination and the intermediary jurisdiction affects the effective tax rate
• income type and duration: dividends, interest, and royalties are subject to different withholding rates, requiring long-term planning
• shareholding relationships: qualified participations (25% or more) often benefit from lower tax rates
• documentation: access to treaty benefits requires valid documentation, including residency certificates and supporting materials

DTAAs are long-term arrangements that can be revised based on mutual agreements between countries. Regular updates reflect changes in global tax policies and international cooperation standards.
