Introduction
Turkey is a significant destination for foreign investors due to its strategic location between Europe, Asia and the Middle East, developed industrial base, logistics infrastructure, domestic market size and access to regional trade routes. Foreign investors may establish companies in Turkey for manufacturing, export, technology, e-commerce, construction, energy, logistics, real estate, finance, professional services and regional management operations. However, a successful investment structure requires more than company incorporation. Foreign-owned companies must understand and comply with Turkish tax law from the first day of operation.
The taxation of foreign-owned companies in Turkey is based on the principle that foreign investors are generally treated equally with domestic investors, unless special laws or international agreements provide otherwise. The Turkish Foreign Direct Investment Law No. 4875 provides that foreign investors are free to make foreign direct investments in Turkey and are subject to equal treatment with domestic investors. It also recognizes the right of foreign investors to transfer abroad net profits, dividends, sale or liquidation proceeds, compensation payments, license and management fees, and loan-related reimbursements and interest payments, subject to applicable law and tax rules.
From a tax perspective, a foreign-owned Turkish company is generally subject to the same corporate tax, VAT, withholding tax, payroll, e-invoice, e-ledger and accounting obligations as a locally owned Turkish company. The fact that the shareholders are foreign does not exempt the company from Turkish tax compliance. On the contrary, foreign-owned companies often face additional tax issues such as double taxation treaty planning, dividend withholding tax, transfer pricing, cross-border service payments, royalty payments, shareholder loans, permanent establishment risk and profit repatriation.
As of 2026, ordinary companies in Turkey are generally subject to a 25% corporate income tax rate, while banks and certain financial sector companies are generally subject to a 30% corporate income tax rate. Resident companies are taxed on their worldwide income, while non-resident entities are taxed only on Turkish-source income. VAT is another core obligation, with generally applied VAT rates of 1%, 10% and 20% depending on the goods or services.
This guide explains the main tax obligations and planning issues for foreign-owned companies operating in Turkey.
1. Legal Status of Foreign-Owned Companies in Turkey
A foreign investor may establish a Turkish company with 100% foreign shareholding. The most common forms are the joint stock company, known as Anonim Şirket or A.Ş., and the limited liability company, known as Limited Şirket or Ltd. Şti.. Both are capital companies and both are subject to corporate income tax. The choice between these forms depends on governance expectations, share transfer plans, number of shareholders, investment strategy, financing needs and future exit planning.
A foreign-owned Turkish company is a Turkish legal entity. It has its own tax number, trade registry record, registered address, statutory books, accounting system, bank accounts, tax office registration and legal personality. Its foreign shareholder does not automatically become the taxpayer for the company’s Turkish profits. Instead, the Turkish company itself is the corporate taxpayer. However, when profits are later distributed to foreign shareholders, dividend withholding tax and treaty planning become relevant.
Foreign investors may also operate through a branch of a foreign company or a liaison office. A branch is not a separate legal entity from the foreign parent, but it may conduct commercial activities in Turkey and is generally taxed on profits attributable to its Turkish activities. A liaison office, by contrast, may not conduct commercial activities or generate income in Turkey. The correct structure should be selected before market entry because the tax consequences of a subsidiary, branch and liaison office can be significantly different.
2. Corporate Income Tax for Foreign-Owned Companies
A foreign-owned Turkish subsidiary is generally treated as a Turkish resident company. Therefore, it is subject to corporate income tax on its worldwide income. In practice, most foreign-owned companies earn income mainly from Turkish operations, but foreign-source income, group income, licensing income and overseas service income may also require analysis.
Corporate taxable income is generally calculated based on statutory accounting profit, adjusted according to Turkish tax law. Deductible expenses may include ordinary and necessary business expenses, salaries, rent, professional fees, cost of goods sold, depreciation, financing expenses, marketing expenses and other business-related costs. However, certain expenses may be non-deductible or limited under Turkish tax law.
For 2026, the standard corporate income tax rate is generally 25% for ordinary companies and 30% for financial sector companies. PwC’s Turkey corporate tax summary also notes that taxable income is computed based on net accounting profit after adjustments for exemptions, deductions and prior-year losses carried forward to a limited extent.
Foreign-owned companies should not focus only on the nominal tax rate. Their effective tax burden may be affected by investment incentives, export income, manufacturing activity, R&D incentives, Technology Development Zone exemptions, foreign tax credits, transfer pricing adjustments, thin capitalization rules and domestic minimum tax rules.
Recent developments should also be monitored closely. In May 2026, Turkey’s parliament approved legislation reported to reduce corporate tax for certain manufacturing companies as part of a package designed to support industry and investment. Because such rules may require secondary legislation, activity-based eligibility and accounting separation, foreign investors should verify the current legal text before applying any reduced rate.
3. Tax Residency and Scope of Taxation
Tax residency is central to the taxation of foreign-owned companies. A Turkish subsidiary is generally a resident taxpayer because it is incorporated and registered in Turkey. It is therefore subject to Turkish corporate tax on worldwide income.
A branch of a foreign company is different. It is generally treated as a non-resident taxpayer and is taxed only on Turkish-source income attributable to the branch. This distinction matters when foreign investors compare a subsidiary and a branch. A subsidiary provides separate legal personality and clearer local operations, while a branch may offer direct integration with the foreign parent but can expose the parent to Turkish operational liabilities.
Foreign companies that do not formally establish a subsidiary or branch may still create Turkish tax exposure if they conduct business in Turkey through a permanent establishment, dependent agent, local project office, construction site or personnel presence. Therefore, foreign companies selling to Turkey, sending employees to Turkey or appointing Turkish representatives should review permanent establishment risk before starting operations.
4. VAT Obligations of Foreign-Owned Companies
VAT is one of the most important tax obligations for companies operating in Turkey. Foreign-owned companies supplying goods or services in Turkey are generally subject to the same VAT rules as domestic companies. VAT applies to commercial, industrial, agricultural and professional supplies, imported goods and services, and other taxable deliveries. The generally applied VAT rates are 1%, 10% and 20%.
A foreign-owned Turkish company must issue invoices with the correct VAT rate, declare output VAT, deduct eligible input VAT, file VAT returns and preserve supporting documents. Input VAT may generally be deducted if the purchase is real, business-related and supported by a legally valid invoice. If input VAT exceeds output VAT, the excess may usually be carried forward, unless a refund mechanism applies.
Exports are generally important for VAT planning. Export sales may be VAT-exempt, and input VAT related to exports may be refundable if documentation requirements are met. Exporters should preserve customs declarations, export invoices, transport documents, foreign customer records, bank collection evidence and accounting reconciliations.
Foreign-owned companies receiving services from abroad should also analyze reverse-charge VAT. If a Turkish company receives foreign consultancy, software, cloud services, advertising, management services, technical support or licensing services used in Turkey, it may need to declare VAT under the reverse-charge mechanism even if the foreign supplier does not charge Turkish VAT.
5. Withholding Tax on Dividends, Interest, Royalties and Services
Withholding tax is a key issue for foreign-owned companies because profits and payments often move across borders. The Turkish subsidiary may pay dividends to foreign shareholders, interest to foreign lenders, royalties to foreign licensors, management fees to group companies or service fees to non-resident providers.
Dividends paid by a Turkish company to a non-resident company or individual are generally subject to 15% withholding tax, unless an applicable double taxation treaty provides a lower rate and treaty conditions are satisfied. Dividend distributions to Turkish resident companies are generally not subject to dividend withholding tax.
Interest payments to non-residents may also trigger withholding tax, depending on the lender and instrument. Royalty payments for trademarks, patents, software, know-how or other intangible rights are another high-risk category. Professional service payments, online advertising payments and management fees may also require withholding tax review depending on the nature of the payment and treaty provisions.
The most important practical point is classification. A payment called “service fee” in the invoice may legally be a royalty if it grants intellectual property use rights. A payment called “reimbursement” may be treated as a service fee if it includes a mark-up. The contract, actual performance and economic substance determine the tax treatment.
6. Double Tax Treaties and Treaty Relief
Turkey has an extensive double taxation treaty network. These treaties may reduce withholding tax on dividends, interest and royalties, prevent double taxation, limit taxation of business profits in the absence of a permanent establishment and provide mutual agreement procedures.
However, treaty protection is not automatic. The foreign shareholder or recipient must generally be a tax resident of the treaty country, provide a valid certificate of residence and satisfy beneficial ownership requirements. If a Turkish company applies a reduced treaty withholding rate without proper documentation, the tax authority may later assess the difference between the domestic rate and treaty rate, together with penalties and late-payment interest.
Foreign-owned companies should prepare treaty files before making outbound payments. These files should include tax residency certificates, shareholder documents, contracts, invoices, beneficial ownership analysis, payment records and legal review of the relevant treaty article.
Treaty planning should also be supported by substance. An intermediate holding company with no employees, no office, no management function and no economic control over income may face treaty abuse challenges. A foreign-owned Turkish company should therefore avoid purely artificial payment routes.
7. Transfer Pricing Rules for Foreign-Owned Companies
Transfer pricing is one of the most important tax compliance areas for foreign-owned companies. Transactions between a Turkish company and its foreign parent, affiliates, group companies or shareholders must comply with the arm’s length principle. These transactions may include goods purchases, service fees, royalties, shareholder loans, guarantees, cost-sharing arrangements, management fees and technical support.
If related-party transactions are not arm’s length, the Turkish tax authority may treat the difference as disguised profit distribution through transfer pricing. This may result in additional corporate tax, withholding tax, VAT adjustments, penalties and late-payment interest.
Foreign-owned companies should prepare intercompany agreements and transfer pricing documentation. The documentation should explain the group structure, related parties, transaction types, functions performed, risks assumed, assets used, pricing method, comparables and conclusion. The OECD’s Turkey transfer pricing profile confirms that Turkey has documentation requirements such as master file, annual transfer pricing report/local file and country-by-country reporting under relevant conditions.
Transfer pricing should be reviewed before transactions occur, not only during tax audit defense. A Turkish subsidiary paying management fees to a foreign parent should be able to prove that the services were actually provided, that it received benefit and that the fee was arm’s length.
8. E-Invoice, E-Archive Invoice and E-Ledger Obligations
Turkey has a highly developed electronic tax compliance system. Foreign-owned companies operating in Turkey must determine whether they are subject to e-Fatura, e-Arşiv Fatura and e-Defter obligations.
E-archive invoice rules became broader for many taxpayers. Official Revenue Administration guidance states that, for certain taxpayers keeping books under the business account basis or taxed under the simple method, e-archive invoice issuance is required where the total amount including taxes exceeds TRY 3,000 between 1 January 2025 and 31 December 2026; for other taxpayers, from 1 January 2026, there is no amount threshold and e-archive invoices must be issued regardless of amount.
E-ledger rules are also important. The Turkish Revenue Administration’s current electronic ledger communiqué states that taxpayers required to keep books on a balance sheet basis must be included in the e-ledger system. This affects many capital companies, including foreign-owned Turkish subsidiaries.
E-document compliance is not merely technical. If a company issues a paper invoice when an electronic invoice is required, or fails to generate legally valid e-ledgers, it may face special irregularity penalties and audit problems. Foreign-owned companies should ensure that accounting software, ERP systems, private integrators, financial seals and internal invoice procedures are compliant with Turkish Revenue Administration requirements.
9. Payroll Tax and Social Security Compliance
Foreign-owned companies employing personnel in Turkey must comply with payroll tax and social security obligations. Employees must be registered with the Social Security Institution before work begins, wages must be calculated correctly, income tax must be withheld, social security premiums must be declared and paid, and payroll records must be preserved.
Payroll compliance is particularly important for foreign managers, expatriates, secondees and remote workers. A foreign manager working physically in Turkey may create payroll tax, work permit, social security and permanent establishment issues. Foreign-owned companies should carefully document whether a person is an employee, independent contractor, board member, consultant or secondee.
Underreporting wages, employing staff without registration or misclassifying employees as freelancers can lead to significant social security and tax penalties. Payroll records should match employment contracts, bank payments, monthly declarations and accounting entries.
10. Taxation of Profit Repatriation
Foreign investors usually expect to repatriate profits from Turkey. The most common method is dividend distribution. After corporate income tax is paid and corporate law requirements are satisfied, a Turkish company may distribute after-tax profits to its shareholders.
Dividend withholding tax is generally 15% for dividends paid to non-resident companies or individuals, unless reduced by a double taxation treaty. The foreign shareholder may also need to report the Turkish dividend in its country of residence and may claim a foreign tax credit if local law permits.
Alternative repatriation methods include interest on shareholder loans, royalties, management fees, cost-sharing payments, capital reduction and liquidation distributions. These alternatives must be commercially real and legally documented. A company should not use artificial service fees or royalties merely to avoid dividend withholding tax. Such payments may be challenged under transfer pricing, withholding tax and corporate tax rules.
11. Tax Incentives for Foreign-Owned Companies
Foreign-owned companies may benefit from Turkish tax incentives if they satisfy the relevant conditions. Incentives may include corporate tax reduction, VAT exemption for machinery, customs duty exemption, social security premium support, income tax withholding support, R&D deductions, Technology Development Zone exemptions and free zone advantages.
The Investment Office explains that Turkey’s incentive system includes instruments such as VAT exemption for machinery, customs duty exemption, corporate tax reduction, social security premium support, income tax withholding support, interest support, land allocation and R&D/design deductions.
Technology companies operating in Technology Development Zones, R&D centers or design centers may benefit from special tax advantages. Manufacturing and export companies may also benefit from reduced taxation, investment incentives and VAT refund mechanisms. However, incentives are not automatic. The company must obtain required certificates, maintain separate accounting records, document eligible expenses and comply with ongoing conditions.
12. Record-Keeping and Tax Audit Preparedness
Foreign-owned companies must maintain proper books, invoices, contracts, payroll records, e-ledgers, e-invoices, bank records, customs documents, transfer pricing files and tax returns. Turkish tax returns generally remain open to inspection during the statutory limitation period. Tax audits may be selected through risk-based software and may focus on transfer pricing, VAT refunds, thin capitalization, capital decreases, related-party payments, withholding tax and other high-risk areas.
A foreign-owned company should assume that cross-border payments may be reviewed. Payments to the foreign shareholder, parent company or group affiliates should be supported by contracts, invoices, service evidence, benefit analysis, withholding tax calculations, VAT reverse-charge records and transfer pricing documentation.
Tax audit defense is strongest when documents are prepared contemporaneously. A file prepared after an audit begins may not be as persuasive as records maintained during the relevant fiscal year.
13. Common Tax Mistakes by Foreign-Owned Companies
The first common mistake is assuming that foreign ownership creates special tax exemptions. In general, foreign-owned companies are subject to the same Turkish tax rules as domestic companies.
The second mistake is ignoring withholding tax on outbound payments. Dividends, interest, royalties, management fees, online advertising payments and service fees may trigger withholding tax.
The third mistake is applying treaty rates without a tax residency certificate and beneficial ownership analysis.
The fourth mistake is failing to prepare transfer pricing documentation for related-party transactions.
The fifth mistake is issuing paper invoices when e-invoice or e-archive invoice is mandatory.
The sixth mistake is treating management fees and royalties as simple deductible expenses without proving real services or intellectual property use.
The seventh mistake is hiring employees or foreign managers without proper payroll, work permit and social security analysis.
The eighth mistake is failing to separate eligible and non-eligible income when claiming tax incentives.
The ninth mistake is using shareholder loans without reviewing arm’s length interest, thin capitalization and withholding tax.
The tenth mistake is waiting until a tax audit to organize records.
14. Practical Tax Compliance Checklist
A foreign-owned company in Turkey should regularly review the following checklist:
Confirm the correct legal structure: subsidiary, branch or liaison office. Complete tax office registration and accounting setup. Determine corporate tax obligations and effective tax rate. Review VAT treatment for all goods and services. Check whether e-invoice, e-archive and e-ledger obligations apply. File VAT, withholding tax, provisional tax and corporate tax returns on time. Register employees and declare payroll correctly. Review withholding tax before making payments abroad. Obtain tax residency certificates before applying treaty rates. Prepare transfer pricing documentation for related-party transactions. Document management fees, royalties and intercompany services. Review shareholder loans for thin capitalization and arm’s length interest. Preserve contracts, invoices, bank records and e-documents. Check eligibility before using tax incentives. Prepare for possible tax audits with organized annual files.
Conclusion
Taxation of foreign-owned companies in Turkey requires careful planning, continuous compliance and strong documentation. Foreign investors may freely establish companies in Turkey and are generally treated equally with domestic investors, but foreign ownership does not eliminate Turkish tax obligations. A foreign-owned Turkish company must comply with corporate income tax, VAT, withholding tax, e-invoice, e-ledger, payroll, social security, transfer pricing, record-keeping and tax audit rules.
The standard corporate income tax rate is generally 25% for ordinary companies and 30% for financial sector companies, while VAT is commonly applied at 1%, 10% or 20% depending on the transaction. Dividend distributions to foreign shareholders are generally subject to 15% withholding tax unless reduced by a double taxation treaty. Related-party payments must be arm’s length and documented. Electronic tax compliance is increasingly important, especially because e-archive and e-ledger obligations have expanded in recent years.
For foreign investors, the safest approach is preventive tax planning. Before establishing or operating a company in Turkey, investors should decide the correct structure, model the tax burden, review treaty protection, prepare payroll and VAT systems, set up e-document compliance, document intercompany transactions and create a tax audit file. A well-structured foreign-owned company can operate efficiently, repatriate profits lawfully and reduce tax risk. A poorly documented structure may face withholding tax assessments, denied deductions, VAT problems, transfer pricing adjustments, penalties and audit disputes.
In this respect, taxation of foreign-owned companies in Turkey should not be treated as a routine accounting matter. It is a core element of legal risk management, investment planning and sustainable corporate governance.
