How to Establish a Liaison Office in Turkey: Step-by-Step Guide (2026)

Foreign companies often choose to establish a liaison office (representative office) in Turkey as a low-cost, low-commitment way to explore the market without forming a full company. A liaison office is essentially an extension of a foreign parent company in Turkey, permitted to conduct certain non-commercial activities (like market research and networking) but strictly forbidden from any profit-generating business.

This guide provides a comprehensive, formal overview of how to set up a liaison office in Turkey, from legal definitions and restrictions to the step-by-step establishment process, post-registration obligations, required documentation, costs, and the role of legal counsel.

Legal Framework for Establishing a Liaison Office in Turkey

Under Turkish law, a liaison office is defined as a non-commercial representation of a foreign company, established for limited purposes such as market research, representation, and information gathering. Its legal basis is set out in the Foreign Direct Investment Law No. 4875 of 2003 and the related Regulation.

The authority responsible for reviewing applications and issuing permits is the General Directorate of Incentive Implementation and Foreign Investment (GDIIFI) within the Ministry of Industry and Technology. Any foreign company duly incorporated abroad may apply for such a permit, provided it undertakes not to conduct commercial or revenue-generating activities in Turkey.

Initial permits are granted for a maximum of three years and are limited to the specific scope of activities declared in the application. Extensions must be requested before the permit expires and are granted based on the office’s prior activities and future plans. Certain liaison offices established exclusively for market research or promotional purposes are not eligible for renewal and must either conclude their operations or transition into a different legal structure after the initial term.

In addition to the FDI Law and its Regulation, liaison offices are indirectly subject to tax and labor legislation to the extent applicable. Operating without the requisite permit, or exceeding the legally defined scope of activities, may result in administrative sanctions or revocation of the license.

Permitted Activities of a Liaison Office in Turkey

The primary function of a liaison office is to provide foreign investors with a presence in Turkey for the purposes of market analysis and support of overseas operations, without engaging in direct commercial activity. Turkish law limits these offices to activities that do not generate income. Permissible activities include:

Market Research: Collecting data on market conditions, consumer behavior, competitors, and investment opportunities.
Representation and Networking: Establishing contacts with local businesses, public authorities, or potential customers, and hosting meetings on behalf of the parent company. The office may act as a communication channel by directing potential clients to the headquarters abroad.
Promotion and Branding: Promoting the parent company’s products or services and enhancing brand visibility through trade fairs, advertising, and public relations. provided no contracts or sales are concluded locally.
Supplier and Quality Control: Monitoring local suppliers or contractors to ensure compliance with the parent company’s standards and specifications.
Technical Support and Training: Offering non-revenue generating technical assistance to distributors or customers and providing training related to the parent company’s products.
Regional Coordination: Acting as a regional management center to supervise investments or administrative operations in Turkey and neighboring countries. Such offices may be granted longer initial permits, up to ten years, due to their broader scope.
Information Transfer: Monitoring economic, legal, or sectoral developments in Turkey and reporting findings to the parent company.

All permissible activities share the defining characteristic that they must not involve profit-making transactions. The liaison office serves strictly as an information and coordination platform, without the authority to execute local sales agreements or issue invoices.

The scope of permitted activities must be clearly defined in the initial application, and the office is legally required to adhere to this scope. If a company intends to engage in sales or other commercial operations, it should establish a branch or subsidiary rather than relying on a liaison office.

What a Liaison Office in Turkey Cannot Do (Commercial Activity Restrictions)

Turkish law strictly prohibits liaison offices from engaging in commercial or revenue-generating activities. This prohibition is a fundamental condition of their operating license. Accordingly, liaison offices are not permitted to conduct sales, manufacturing, or fee-based services, nor may they issue invoices or execute contracts in their own name.

All commercial transactions must be carried out directly by the foreign parent company or a duly established Turkish entity. While the legislation does not exhaustively define “commercial activity,” it clearly encompasses selling or marketing goods and services, receiving payments, issuing quotations or purchase orders, and accepting customer orders. If contractual negotiations occur, any resulting agreement must be executed by the parent company or its Turkish branch or subsidiary, never by the liaison office itself.

Engaging in unauthorized business activity undermines the legal purpose of a liaison office and is subject to strict enforcement. Where the Ministry determines that a liaison office has generated income in Turkey, its license will be revoked and administrative fines imposed. Tax authorities may also reclassify the office as a taxable entity, thereby subjecting it to corporate and other tax liabilities equivalent to those of a local company. For this reason, foreign companies must implement effective internal controls to ensure that their liaison office operates strictly within its non-commercial mandate.

The legal restrictions are balanced by significant fiscal privileges. Liaison offices are exempt from corporate income tax, value-added tax, and withholding tax on most transactions. These exemptions apply only while the office remains within its permitted scope. Any departure into taxable commercial activity would result in the loss of these benefits and the imposition of corresponding liabilities and penalties

How to Establish a Liaison Office in Turkey: Step-by-Step Guide

The establishment of a liaison office in Turkey requires obtaining a permit from the Ministry of Industry and Technology (General Directorate of Incentive Implementation and Foreign Investment – GDIIFI), followed by certain administrative registrations. The principal steps are as follows:

1. Eligibility Requirements and Documents for Establishing a Liaison Office in Turkey

The foreign parent company must be a legally incorporated and operational entity abroad, generally with at least one year of activity. No minimum capital investment is required, but all expenses must be funded from abroad. Required documents include the certificate of incorporation (or activity certificate), financial statements, a board resolution or authorization letter, and a written undertaking confirming that the office will not engage in commercial activities. All documents issued abroad must be apostilled or consularized, and translated into Turkish by a sworn translator.

2. Submitting Liaison Office Application to the Ministry

The application consists of the Ministry’s standard form and supporting documents. The application must clearly define the intended activities and requested duration (up to three years initially). The Ministry reviews the submission and typically issues a decision, in practice the process may take up to four weeks.

3. Obtaining the Liaison Office Permit from the Ministry of Industry and Technology

If approved, the Ministry issues an official permit letter specifying the permitted activities and the validity period (up to three years). A liaison office is thereby legally established, with no requirement to register in the Trade Registry. If the application is rejected, the company may revise and resubmit, or consider alternative structures such as a branch.

4. Tax Registration for Liaison Offices in Turkey

Despite not engaging in taxable business, a liaison office must register with the local tax office to obtain a tax identification number, necessary for withholdings. The application includes the Ministry permit, office lease agreement, and representative’s identification. Within one month of obtaining the permit, the company must notify the Ministry by submitting proof of tax registration and office lease.

5. Opening a Bank Account for a Liaison Office in Turkey

The office must maintain at least two accounts in Turkey: one in foreign currency and one in Turkish Lira. All funding must be transferred from abroad in foreign currency, then converted to TRY to meet local expenses. Required documentation includes the tax number, lease agreement, identification of the signatory, and the permit letter.

6. Registering a Liaison Office with the Social Security Institution (SGK)

If employing staff, the office must register as an employer with the SGK, obtain an employer number, and enroll employees to ensure social security coverage. All employees must be insured under Turkish law.

7. Obtaining Work Permit for Foreign Employees for Liaison Office in Turkey

While liaison offices may freely employ Turkish nationals, foreign employees require work permits. Unlike other entities, liaison offices are allowed to employ one foreign “key personnel” (chief representative) without meeting the general ratio of five Turkish employees per foreigner, provided that at least 200.000 USD is transferred from abroad within the preceding year. The office applies to the Ministry of Labor with supporting documentation, including the liaison office permit and proof of funding. Once granted, the work permit is tied to the validity of the liaison office permit and must be renewed concurrently. Additional foreign hires are subject to the general work permit rules (five Turkish citizens must be employed for each foreigner).

8. Commencement of Operations for a Liaison Office in Turkey

After completing these registrations, the liaison office may commence operations. As it is not a separate legal entity, no Trade Registry registration is required. The office must operate strictly within its permitted scope, and all correspondence, business cards, and signage should clearly identify it as a “Liaison Office” of the foreign parent.

Consequently, with proper preparation, a liaison office can typically be established within three to four weeks. The permit from the Ministry constitutes the critical approval, while subsequent registrations ensure compliance with tax, banking, and labor obligations.

Post-Establishment Compliance and Obligations

Establishing a liaison office is only the initial step, maintaining compliance with ongoing obligations is essential to preserve good standing, secure permit extensions, or effect a proper termination. The principal duties are as follows:

Annual Activity Reporting: Each year, liaison offices must file an Annual Activity Information Form with the Ministry of Industry and Technology, by the end of May. The report outlines activities conducted, foreign funds transferred, expenditures, staffing levels, and a description of operations. Failure to file on time may jeopardize permit extensions or result in cancellation.

Funding Requirements: All expenses must be covered by foreign currency transferred from the parent company. Local revenue or Turkish Lira transfers from the parent are not permitted. Offices must retain Foreign Exchange Purchase Documents (DAB) as proof of conversions. During permit renewals, the Ministry may request a bank confirmation letter evidencing the cumulative amount of foreign funds remitted.

Bookkeeping and Record-Keeping: Although liaison offices are not subject to commercial accounting or corporate tax filings, they must maintain orderly financial records, including invoices, rent receipts, payroll files, and bank statements. As limited taxpayers, they are obliged to withhold and remit taxes on certain payments, such as rent and to pay stamp duty on relevant contracts.

Tax Obligations: Liaison offices are exempt from corporate income tax, VAT, and income tax on salaries paid from abroad, pursuant to Article 23/1-14 of the Income Tax Law. However, they remain responsible for withholding 20% tax on rent, stamp duty on agreements (e.g., leases), and social security contributions (approximately 32.5% of gross wages) for employees.

Employment Law Compliance: Liaison offices must comply fully with Turkish labor legislation, including rules on employment contracts, working hours, severance, and occupational health and safety. Salaries of Turkish staff are exempt from income tax if paid in foreign currency from abroad, but social security contributions must be paid monthly. Foreign employees require valid work permits.

Notifications of Changes: Significant changes, such as relocation of the office, replacement of the liaison officer, or changes in the parent company’s name or ownership must be reported to the Ministry within one month, supported by the necessary documentation. Delays may be treated as violations of permit conditions.

Permit Renewal: Initial permits are granted for up to three years. Applications for renewal must be submitted before expiry, supported by past activity reports, evidence of foreign fund transfers, staffing details, and the parent company’s future plans. The Ministry may grant extensions of two to three years, or up to five years for regional management offices. By contrast, offices established solely for market research or promotional purposes cannot be extended beyond the initial term.

Termination: To close a liaison office, the company must obtain tax clearance from the local tax office and submit a termination notice to the Ministry. All outstanding liabilities, including rent, employee entitlements, and social security premiums, must be settled. Remaining foreign currency balances may then be repatriated to the parent company. Once the Ministry processes the closure, the permit is cancelled, and any future office would require a new application.

Conclusion: Compliance obligations for liaison offices are limited compared to full companies but remain essential. Annual reporting, exclusive foreign funding, proper record-keeping, and strict adherence to the non-commercial mandate are non-negotiable. By observing these requirements, a liaison office can operate effectively while benefiting from its tax-exempt status.

Estimated Expenses and Operational Costs

A liaison office is generally more cost-effective than establishing a full subsidiary. Nonetheless, certain establishment and operational costs must be anticipated. The following overview uses USD as the reference currency.

Application, Notary and Translation Fees: The Ministry does not charge fee for the application. However, expenses for notarization, translation, apostille, or consular legalization of documents typically range from 1.000 – 2.000 USD depending on volume and jurisdiction.
Professional Advisory Fees: Foreign investors commonly engage local legal counsel or consultants. These services reduce risks of delay or rejection and ensure compliance.
Office Rent and Utilities: A physical office address is mandatory. In major cities such as Istanbul or Ankara, monthly rent for modest office space in a business district ranges between 1.000 – 2.000 USD. Utilities (electricity, water, internet) depending on the usage add approximately USD 100-200 monthly.
Personnel Costs: Salaries represent a significant portion of the budget. Because salaries funded from abroad are exempt from Turkish income tax and stamp duty, the employer’s primary obligation is social security contributions (approximately 32.5% of gross salary, with 22.5% borne by the employer).
Administrative and Compliance Costs: Outsourced accounting, payroll, and annual reporting services. Notary services for occasional document certification and service fees for filings or renewals (commonly USD 500 or more) should also be considered.

Required Documents for Establishing a Liaison Office in Turkey

When applying for a liaison office permit, the foreign company must submit a complete dossier of documents to the Ministry of Industry and Technology (General Directorate of Incentive Implementation and Foreign Investment). The principal requirements are as follows:

Application Form: A standard form obtained from the Ministry, containing the parent company’s details, the proposed liaison office address in Turkey, and the scope of activities. It must be duly completed and signed by an authorized representative.
Letter of Commitment: A declaration signed by the appointed liaison office manager, setting out the intended activities of the liaison office and expressly confirming that it will not engage in commercial operations. This letter must be signed by the appointed liaison officer with the proof of the signatory’s authority (board resolution or signatory circular).
Certificate of Activity: An official extract from the relevant authority in the company’s home jurisdiction (chamber of commerce record) proving the company’s legal existence and current status. This document must be apostilled.
Financial Documentation: The parent company’s most recent annual report or audited financial statements, duly apostilled. These documents demonstrate the company’s financial standing. At least one year of financial history is required.
Authorization for the Liaison Officer: Apostilled board resolution appointing the individual responsible for managing the liaison office in Turkey. This must specify the representative’s name, surname. The letter of commitment must be signed by the the appointed individual who is responsible for managing the liaison office in Turkey.
Power of Attorney: A notarized and apostilled power of attorney is required. This authorizes the representative to act before the Ministry and other institutions, including tax registrations.
Articles of Association: Company’s Articles of Association is required. These should be apostilled and translated into Turkish.

All documents originating abroad must be apostilled and sent pyhscially to attorney’s office. Then the documents will be translated into Turkish at the Turkish notaries. The Ministry retains verified copies and returns originals upon inspection.

Consistency across all documents is essential; company names, dates, and other details must match exactly. Discrepancies can cause delays or additional inquiries. It is advisable to provide a cover letter and index of documents to facilitate the Ministry’s review.

In conclusion, the preparation and certification of documents constitute one of the most time-consuming aspects of the process. Once the Ministry verifies compliance with all formal requirements and receives the undertaking not to engage in commercial activity, (if the other conditions are met) approval is typically granted within few weeks.

The Role of Legal Counsel in Establishing a Liaison Office in Turkey

Engaging an experienced Turkish attorney is strongly recommended when establishing a liaison office. The procedure requires navigating complex legal formalities and dealing with multiple administrative authorities, which can be challenging without local expertise.

An attorney’s role typically encompasses the following:

Feasibility and Scope Assessment: At the planning stage, counsel determines whether a liaison office is the appropriate vehicle for the company’s intended activities and advises if an alternative structure, such as a branch or subsidiary, would be more suitable. This prevents unsuccessful applications and future compliance risks.
Document Preparation and Compliance: Legal counsel ensures that all required documents are prepared in accordance with Turkish law, including drafting the undertaking letter, coordinating sworn translations, and securing apostilles or consular certifications. Properly prepared documents significantly reduce the risk of rejection.
Representation Before Authorities: Acting under a power of attorney, the attorney files the application with the Ministry of Industry and Technology and serves as the primary contact point throughout the review process. Any requests for clarification or additional documentation are addressed promptly, thereby expediting approval.
Post-Permit Registrations: Following the issuance of the permit, counsel coordinates complementary registrations such as tax office and social security enrollment, assists with bank account openings, and drafts employment contracts in compliance with Turkish labor law. The attorney also advise on work permit applications for foreign personnel.
Ongoing Compliance and Renewal: Attorneys monitor deadlines for annual activity reports, assist with their preparation, and manage permit renewal applications. They also represent the company in the event of Ministry inquiries or inspections, ensuring continued compliance.
Operational Legal Guidance: Throughout the office’s operation, legal counsel provides advice on permissible activities and reviews agreements or events to prevent violations of the non-commercial mandate. They also inform the company of regulatory developments affecting liaison office operations.
Termination: Should the company decide to close the liaison office or convert it into a branch or subsidiary, the attorney oversees tax clearance, notifies the Ministry, ensures all obligations are settled, and manages the transition without legal or administrative disruption.

In conclusion, legal counsel provides assurance that the liaison office remains fully compliant with Turkish law at all times. Given the strict regulatory framework governing liaison offices, even minor procedural oversights may result in cancellation of the permit or other sanctions. Accordingly, the engagement of experienced legal professionals is a prudent investment that safeguards the company’s interests and facilitates efficient interaction with Turkish bureaucracy.

Frequently Asked Questions (FAQs)

1-How is a Liaison Office Different From a Branch or Subsidiary in Turkey?

A liaison office is a non-commercial representative office, it cannot generate profit or sign contracts in its own name and does not enter the Trade Registry. A branch, by contrast, is an extension of the parent company that can conduct business in Turkey, issue invoices, and is taxed on local income. A subsidiary is a separate Turkish legal entity (e.g., joint-stock or limited company) fully engaged in commerce and independently registered. Unlike branches and subsidiaries, liaison offices are time-limited (initially 3 years, subject to renewal) and serve mainly for market research and representation, not active trade.

2-Can a Liaison Office Engage in Revenue Generating Activities or Solicit Business in Turkey?

No. Liaison offices are strictly prohibited from conducting sales, earning income, issuing invoices, or signing commercial contracts. Their role is limited to non-commercial functions such as research, networking, promotion without sales, and reporting to headquarters. All business inquiries must be referred to the parent company or its local branch/distributor. Companies intending to trade in Turkey must establish a branch or subsidiary, as liaison offices are not permitted to engage in commerce.

3-How Long Can a Liaison Office Operate, and Can the Permit be Extended?

An initial permit is granted for up to 3 years. Extensions are usually approved in 2–3 year periods, based on the office’s activities and the parent company’s plans. Offices established solely for market research or promotion cannot be renewed beyond the first term, while broader functions such as regional management may be extended, sometimes up to 5 years. Renewal requests should be filed before the permit expires, ideally 60 days in advance to avoid lapses that would require closure.

4-What Taxes Are Liaison Offices in Turkey Subject to?

Liaison offices are exempt from corporate income tax, VAT, and income tax on salaries paid from abroad. However, they must withhold tax on certain payments such as rent, pay the employer’s share of social security contributions, and cover stamp duty on specific contracts. Their tax obligations are thus limited to withholding and transaction-based liabilities, provided they remain within their non-commercial scope.

5-Can a Liaison Office Hire Staff, Including Foreign Nationals?

Yes. A liaison office may freely employ Turkish nationals in compliance with labor and social security law. One foreign key personnel may be appointed without applying the “five Turkish employees per one foreign employee” rule, provided the office has received at least 200.000 USD in funding from abroad within the last year. For any additional foreign hires, the “five Turkish employees per one foreign employee” rule applies, and all labor law obligations remain fully applicable.

6-Does the Location Within Turkey Affect the Establishment of a Liaison Office?

No. Turkey is a unitary state with a centralized legal framework. Therefore, the legal requirements and procedures for establishing a liaison office are uniform throughout the country. Regardless of whether the office is located in Istanbul, Ankara, Izmir, or another province, the application is submitted to the Ministry of Industry and Technology and is subject to identical rules. Subsequent registrations with the relevant local tax office and Social Security Institution are merely administrative in nature and do not alter the substantive legal process. There are no regional variations in law or procedure, the license granted is national in scope.
