Liaison Office Setup in Turkey for Foreign Companies: Ministry Approval and Tax Exemptions Guide

Liaison Office Setup in Turkey for Foreign Companies: Ministry Approval and Tax Exemptions Guide

Foreign corporations seeking to explore the Turkish market, audit local manufacturing suppliers, provide technical support to regional distributors, or establish a regional management hub between Europe, the Middle East, and the CIS do not always need to incorporate a full commercial subsidiary (A.Ş. or Ltd. Şti.) from day one. Under Turkish foreign investment legislation, legal entities incorporated under the laws of a foreign country are entitled to establish a Liaison Office (İrtibat Bürosu / Representative Office) in Turkey, provided that the office does not engage in any revenue-generating commercial activities.

Governed by Article 3(h) of the Foreign Direct Investment Law (Law No. 4875) and Articles 6–8 of the Regulation on the Implementation of the FDI Law, liaison offices operate under an operating permit issued by the Ministry of Industry and Technology (General Directorate of Incentive Implementation and Foreign Capital). Because a liaison office generates no commercial revenue in Turkey and is funded entirely by foreign currency remittances from its parent company abroad, it benefits from an extraordinary tax regime: 0% Corporate Income Tax, no VAT filing obligations, and a 100% Income Tax and Stamp Tax exemption on employee salaries under Article 23/14 of the Turkish Income Tax Law (Law No. 193).

Executive Legal Summary (Key Takeaways):

• Ministry Permit & 3-Year Initial Term (Law No. 4875 Art. 3/h): Foreign companies that have been actively operating in their home country for at least 1 year may obtain an operating permit from the Ministry of Industry and Technology to establish a Liaison Office in Turkey for an initial term of up to 3 years.
• Strict Prohibition on Commercial Activity: A Liaison Office has no separate legal personality and no share capital; it is strictly prohibited from issuing invoices, signing sales contracts, collecting customer payments, or generating commercial profit in Turkey. All office expenses must be funded via foreign currency transfers from the parent company abroad.
• 0% Corporate Tax & 100% Salary Income Tax Exemption (ITL Art. 23/14): Liaison offices are completely exempt from Turkish Corporate Income Tax (25%) and VAT. Furthermore, salaries paid to local and expatriate employees out of foreign currency remitted by the foreign parent company are 100% exempt from Turkish Income Tax (15%–40%) and Stamp Tax pursuant to Income Tax Law Art. 23/14.
• Annual May E-TUYS Reporting Obligation: Every Liaison Office must register on the Ministry's electronic E-TUYS portal and submit an annual activity report alongside bank foreign exchange certificates by the end of May each year to maintain its license.

1. Legal Nature of a Liaison Office and the 1-Year Parent Company Rule

Pursuant to Article 3(h) of Foreign Direct Investment Law No. 4875 and Articles 6–7 of its Implementation Regulation, a Liaison Office is a non-commercial representative unit of a foreign corporation authorized exclusively to conduct preparatory, auxiliary, and coordination activities in Turkey.

Unlike a Turkish Joint-Stock Company (A.Ş.), Limited Liability Company (Ltd. Şti.), or Foreign Branch (Şube), a Liaison Office possesses distinct structural features:

1. No Independent Legal Personality or Capital Requirement: A Liaison Office is not a separate legal entity and requires no subscribed share capital or pre-registration bank deposit. It acts as a direct extension of the foreign parent corporation, which remains directly liable for the office's lease, employment contracts, and administrative obligations.
2. Exemption from Trade Registry Registration: Liaison offices are not registered with the Turkish Trade Registry (Ticaret Sicili) or local Chambers of Commerce. Once the operating permit is issued by the Ministry of Industry and Technology, the office is registered solely with the local Tax Office (to obtain a tax number for lease withholding and social security tracking) and the Social Security Institution (SGK).
3. Mandatory 1-Year Operational History of the Foreign Parent (Regulation Art. 7): To prevent newly formed shell companies from abusing the tax exemptions of a liaison office, the Ministry requires proof that the foreign parent company has been incorporated and actively operating in its home jurisdiction for at least 1 full year prior to the application (evidenced by audited financial statements and an activity report).

2. Permitted Activity Scopes, the 3-Year Term Limit, and License Extensions

Under Article 8 of the Implementation Regulation on the FDI Law, initial Liaison Office operating permits are granted for a maximum of 3 years; while market research permits cannot be extended beyond 3 years, permits for quality control, technical support, and regional management hubs may be renewed for successive 5- to 10-year terms.

Selecting the correct activity category in the initial Ministry application is critical, as it dictates whether the office can remain open beyond the first three years:

• 1. Market Research & Promotion of Parent Company Products/Services: Granted for a maximum of 3 years; operating permits issued under this category cannot be extended under any circumstances (after 3 years, the foreign company must transition to a commercial subsidiary or branch).
• 2. Representation and Hosting: Representing the parent company before regional institutions and coordinating business contacts (renewable for up to 5 years per extension).
• 3. Supplier Auditing, Quality Control & Local Sourcing: Auditing Turkish manufacturers, inspecting production quality, and coordinating sourcing for the foreign parent company (renewable for up to 5 years per extension).
• 4. Technical Support and Training: Providing after-sales technical assistance, engineering support, and training to the parent company's Turkish distributors or clients without charging fees (renewable for up to 5 years per extension).
• 5. Regional Management Center (Bölgesel Yönetim Merkezi): Coordinating management, logistics, R&D, supply chain, and brand supervision for the parent company's affiliates across multiple countries (renewable for up to 10 years per extension).

3. Strict Prohibition on Commercial Activities and Permanent Establishment (PE) Risks

Pursuant to Article 8(e) of the FDI Implementation Regulation, Liaison Offices are strictly prohibited from engaging in direct or indirect commercial activities, issuing invoices, or concluding revenue-generating contracts in Turkey.

Crossing the line between preparatory support and active commerce carries severe legal and fiscal penalties:

1. Prohibited Transactions: A Liaison Office cannot negotiate and sign binding sales agreements on behalf of the parent company, issue commercial invoices, store and sell inventory domestically, or receive payments from Turkish customers into its bank accounts. All commercial contracts, invoicing, and payment collections must occur directly between the foreign parent company abroad and the customer.
2. License Revocation and Retroactive "Permanent Establishment" Taxation: If a Ministry inspection or tax audit reveals that the Liaison Office has engaged in commercial sales or acted as a dependent commercial agent concluding contracts, the Ministry immediately revokes the operating permit. Simultaneously, the Turkish Tax Authority reclassifies the office retroactively as a Permanent Establishment (Dar Mükellef İşyeri / Daimi Temsilci — Corporate Tax Law Art. 3/3), assessing retroactive 25% Corporate Tax, 20% VAT, salary income taxes, late interest, and a 100% tax loss penalty (vergi ziyaı cezası).

4. Tax Exemptions: 0% Corporate Tax and the 100% Salary Income Tax Exemption (ITL Art. 23/14)

Under the Turkish Corporate Tax Law (No. 5520) and Article 23/14 of the Turkish Income Tax Law (No. 193), a compliant Liaison Office pays 0% Corporate Tax and 0% VAT, while salaries paid to its employees in foreign currency remitted from abroad are 100% exempt from Turkish Income Tax and Stamp Tax.

This statutory tax shield provides three major financial advantages:

1. Complete Exemption from Corporate Tax and VAT (0%): Because the Liaison Office has no commercial income, it is not registered as a Corporate Income Tax or VAT taxpayer and files no monthly VAT or quarterly/annual corporate tax returns (only withholding tax / muhtasar declarations for office rent are filed).
2. 100% Employee Salary Income Tax & Stamp Tax Exemption (ITL Art. 23/14): Pursuant to Article 23/14 of Income Tax Law No. 193, wages paid to employees working at a Liaison Office (applicable to both Turkish citizens and foreign expatriate staff) are 100% exempt from progressive Turkish Income Tax (which normally ranges from 15% to 40%) and Stamp Tax (0.759%), provided three statutory conditions are met: (a) the employer is a non-resident entity without a commercial business center in Turkey, (b) the salaries are funded out of earnings generated by the parent company outside Turkey, and (c) the funds are transferred from abroad into Turkey in foreign currency (documented via official bank FX transfer receipts). This reduces total payroll costs by roughly 30% to 40% compared to a Turkish subsidiary.
3. Social Security (SGK) Contributions: The ITL Art. 23/14 tax exemption applies only to Income Tax and Stamp Tax; it does not exempt the office from Social Security premiums. Turkish employees (and foreign employees not covered by a home-country Certificate of Coverage under a bilateral social security treaty) must be registered with SGK under Law No. 5510.

6. Key Personnel Work Permits and Mandatory Annual May E-TUYS Filings

Under the Regulation on the Implementation of the FDI Law and International Labor Law No. 6735, Liaison Offices enjoy streamlined work permit criteria for their appointed foreign representative, subject to strict annual foreign currency reporting on the E-TUYS portal.

Maintaining a Liaison Office in good standing requires compliance with two administrative rules:

1. Work Permit for the Foreign Office Representative: A foreign national appointed as the authorized representative (Büro Yetkilisi) of the Liaison Office may obtain a Turkish Work Permit without being subject to the standard 500,000 TRY share capital rule (for extensions and additional key personnel, the Ministry verifies that at least 200,000 USD or equivalent foreign currency was remitted from the parent company during the preceding year).
2. Post-Opening Registration & Annual May E-TUYS Declarations (Regulation Art. 8/c): Within 1 month of receiving the Ministry permit, the office must submit its Tax Office registration certificate and office lease agreement to the Ministry. Thereafter, every year by the end of May at the latest, the Liaison Office must upload the "Information Form on Liaison Office Activities" (Ek-4) alongside official bank letters proving all foreign currency transfers received from the parent company during the previous calendar year via the E-TUYS electronic system. Failure to file the annual May declaration results in cancellation of the operating permit.

7. Gönen Law Office 4-Stage Liaison Office Setup & Tax Compliance Protocol

Our corporate and tax law teams manage the end-to-end establishment, payroll structuring, and ongoing Ministry compliance of Liaison Offices in Turkey through a 4-stage legal protocol:

1. Strategic Activity Scope Selection & Apostilled Dossier Preparation: We structure the application under a renewable activity category (Quality Control/Supplier Auditing, Technical Support, or Regional Management) to ensure long-term extensibility beyond 3 years, and prepare the parent company's Certificate of Activity, 1-year audited financial statements, Board resolution, Power of Attorney, and Parent Undertaking with Hague Apostille or consular legalization.
2. Ministry of Industry and Technology Licensing & E-TUYS Authorization: We file the operating permit application before the General Directorate of Incentive Implementation and Foreign Capital in Ankara and complete electronic signature authorization on the E-TUYS portal.
3. Tax Office, SGK, Dual-Currency Banking & ITL Art. 23/14 Payroll Setup: Upon permit issuance, we register the office with the Tax Office and SGK, open corporate FX and TRY bank accounts, and establish the compliant payroll architecture required to secure the 100% salary Income Tax exemption under ITL Art. 23/14.
4. Expatriate Work Permits, Annual May E-TUYS Filings & Subsidiary Transition: We obtain the Work Permit for the foreign Liaison Office Director, submit the mandatory annual May E-TUYS activity and FX reports, and—when the parent company is ready to commence direct sales—manage the seamless closure of the Liaison Office and incorporation of a Turkish A.Ş. or Ltd. Şti.
