For international enterprises evaluating expansion into Türkiye, establishing a compliant, low-risk operational foundation is essential before committing substantial capital or engaging in direct commercial activities. Under Turkish corporate law, foreign entities seeking a non-commercial presence to conduct market research, coordinate regional suppliers, or manage public relations can utilize a Liaison Office (İrtibat Bürosu).
Regulated under the Foreign Direct Investment Law No. 4875 (FDI Law) and overseen by the Ministry of Industry and Technology, a liaison office offers foreign firms an established statutory mechanism to operate locally without forming a joint-stock company, limited liability corporation, or commercial branch.
This comprehensive guide details the governing legal frameworks, qualification criteria, step-by-step application workflows, tax exemptions, and annual reporting mandates for establishing a liaison office in Türkiye.
1. Statutory Foundations and Fundamental Principles
The primary legal basis for foreign liaison offices resides in Article 3(h) of FDI Law No. 4875. This provision empowers the Ministry of Industry and Technology to evaluate, approve, and renew operational permits for legal entities organized under foreign laws.

FOREIGN PARENT COMPANY TURKISH LIAISON OFFICE
(Incorporated Outside Türkiye) (Non-Commercial Base)
• 100% funding via foreign transfers • No independent legal personality
• Retains direct operational control • Prohibited from commercial sales
• Remits foreign currency funds • Conducts research & representation
Essential Legal Rules:
- Absence of Separate Legal Personality: A liaison office is a direct structural extension of its parent company abroad. It lacks independent legal standing, distinct corporate personality, share capital, or articles of association.
- Strict Prohibition of Commercial Activity: By statutory mandate, a liaison office cannot issue commercial invoices, execute sales contracts, generate revenue, or perform paid services within Türkiye.
- Sole Reliance on Offshore Funding: All operating expenses—including real estate leases, employee salaries, utility bills, and vendor services—must be funded entirely through foreign currency remitted from abroad by the parent enterprise.
- Unlimited Parent Liability: Because the liaison office has no distinct legal identity, the foreign parent organization bears full and unlimited liability for all actions, liabilities, and lease obligations incurred by its local office.
2. Permitted Functional Categories
When applying for an establishment permit, the foreign parent firm must select one or more specific non-commercial activity categories authorized by the General Directorate of Incentive Implementation and Foreign Investment:

3. Structural Comparison: Liaison Office vs. Branch vs. Subsidiary
Determining the appropriate market entry model requires evaluating legal rights, tax obligations, operational capabilities, and capital requirements across available structures:
| Structural Criteria | Liaison Office (İrtibat Bürosu) | Branch Office (Şube) | Subsidiary (Ltd. Şti. / A.Ş.) |
|---|---|---|---|
| Legal Status | Fully dependent on parent | Dependent extension of parent | Independent domestic legal entity |
| Commercial Sales Rights | Strictly Prohibited | Permitted | Permitted |
| Parent Company Liability | Direct and unlimited | Direct and unlimited | Limited to committed share capital |
| Minimum Statutory Capital | None | None (Allocated capital needed) | Ltd. Şti.: 50,000 TRY A.Ş.: 250,000 TRY |
| Corporate Income Tax Exposure | Exempt (Zero taxable income) | Standard rate on Turkish profits | Standard rate on global earnings |
| Employee Income Tax Status | Exempt (Subject to Article 23) | Standard progressive tax applies | Standard progressive tax applies |
| Permit / Registration Authority | Ministry of Industry and Technology | Trade Registry / MERSİS | Trade Registry / MERSİS |

4. Multi-Phase Establishment Workflow
Establishing a liaison office involves document legalizations abroad, ministry evaluation, and local tax and administrative setups.

Phase 1: Parent Document Legalization Abroad
Documents created outside Türkiye must be notarized in the home country and authenticated with an Apostille under the Hague Convention (or validated by a Turkish diplomatic mission if the home country is not an Apostille signatory).
Key documentation includes:
- Official Application Form: Comprehensive filing defining the parent company’s history, field of operation, proposed liaison activities, and local office details.
- Letter of Commitment (Taahhütname): A signed declaration stating that the liaison office will refrain from commercial trading, issuing invoices, or earning local income.
- Certificate of Good Standing / Certificate of Activity: Official document from the home country’s trade registry confirming that the parent firm is actively registered, solvent, and operating legally.
- Recent Financial Statements: Audited balance sheet and income statement of the foreign parent firm from the previous fiscal year.
- Board Resolution: Formal resolution adopted by the parent company’s governing board deciding to open a liaison office in Türkiye, establishing its official address, and designating an authorized Chief Representative (Büro Yetkilisi).
- Power of Attorney (PoA): A legal instrument granting the local representative full authority to manage proceedings before government ministries, tax offices, financial institutions, and municipal authorities.
Upon arrival in Türkiye, all apostilled records must be translated into Turkish by a sworn translator and certified by a Turkish Public Notary.
Phase 2: Ministry Submission and Permit Issuance
- The prepared legal dossier is formally submitted to the Ministry of Industry and Technology, General Directorate of Incentive Implementation and Foreign Investment.
- The Ministry charges no statutory filing or evaluation fees for processing liaison office applications.
- Following administrative review (typically completed within 15 to 30 business days), the Ministry issues an official Liaison Office Establishment Permit (İrtibat Bürosu Kuruluş İzni).
- Initial Tenure: Establishment permits are initially issued for a maximum duration of up to 3 years.
Phase 3: Post-Permit Local Setups
Once the establishment permit is granted, the authorized representative must complete localized administrative registrations:
- Tax Office Registration: Although exempt from corporate tax, the office must register with the local tax office to obtain a Tax Identification Number (Vergi Kimlik Numarası) to execute lease agreements, manage tax withholdings, and conduct banking.
- Commercial Office Lease: The representative must execute a rental contract for a physical office location within Türkiye.
- Banking Setups: The liaison office must open dual accounts at a registered commercial bank in Türkiye:
- A Foreign Currency Account to receive capital transfers directly from the foreign parent entity.
- A Turkish Lira (TRY) Account to convert remitted foreign currency to cover local payroll and expenses.
- Social Security Institution Registration (SGK Kaydı): The liaison office must register as an employer with SGK prior to hiring domestic or foreign staff.
- Ministry Confirmation Filing: Within one month of obtaining tax registration and signing the lease, certified copies must be submitted to the Ministry of Industry and Technology to finalize the administrative dossier.
5. Taxation Regime and Wage Incentives
The tax regulations governing foreign liaison offices represent a major incentive for foreign companies exploring the Turkish market.

- Value Added Tax (KDV): The liaison office cannot issue VAT invoices for commercial sales. Conversely, input VAT paid on local office leases, supplies, or professional services cannot be refunded or offset; it is absorbed as a general operating expense.
2. Personal Income Tax Exemption on Employee Salaries
Under Income Tax Law No. 193, Article 23, Paragraph 1, Sub-paragraph 14(a), salaries paid to liaison office employees are exempt from personal income tax (Gelir Vergisi). However, this exemption requires satisfying five cumulative conditions:

All local and foreign employees must be enrolled under Social Insurance and General Health Insurance Law No. 5510, with monthly premiums calculated and paid by the liaison office.
6. Work Permits for Foreign Personnel
Foreign companies setting up a liaison office often send international executives or technical specialists to lead local operations.

- Repatriation of Unused Balances: Any unspent funds remaining in the liaison office’s bank accounts may be remitted back to the foreign parent company following tax clearance.
- Administrative Deregistration: The office cancels its tax, SGK, and municipal records, submitting final deregistration notes to the Ministry of Industry and Technology to cancel the establishment permit.
Executive Summary
Establishing a liaison office in Türkiye provides foreign companies an effective framework to explore local markets, audit regional suppliers, build corporate visibility, and manage strategic relationships without incurring corporate income tax liabilities or minimum share capital commitments.
Achieving long-term compliance requires adhering to core statutory boundaries: the liaison office must refrain from commercial transactions, billing, or revenue generation within Türkiye, and all operational overhead must be funded via foreign currency transfers from abroad. By maintaining accurate banking records, submitting annual activity filings to the Ministry, and respecting permitted functional limits, foreign enterprises can establish a solid foundation in Türkiye.
