Liaison office setup in Turkey explained in English. Learn the legal restrictions, licensing process, document requirements, duration limits, extension rules, work permit issues, and practical use cases for foreign companies in Türkiye.
Introduction
Liaison office setup in Turkey is a useful market-entry option for foreign companies that want a formal presence in Türkiye without immediately launching full commercial operations. Official guidance published by Invest in Türkiye states that any company incorporated under the laws of a foreign country may establish a liaison office in Türkiye upon obtaining a license from the Ministry of Industry and Technology, provided that the foreign company does not engage in any commercial activities in Türkiye. That single restriction is the legal core of the entire liaison office regime. (Yatırım Ofisi)
This matters because many foreign investors mistakenly assume that a liaison office is simply a lighter version of a Turkish subsidiary or branch. It is not. A liaison office is designed for non-commercial presence, not for revenue-generating business. Official Turkish guidance makes that distinction explicit by linking the office’s legality to the condition that no commercial activity be carried out in Türkiye. If the company wants to sell, invoice, sign ordinary operating contracts, or otherwise conduct business in the Turkish market, a liaison office is usually the wrong structure. (Yatırım Ofisi)
From a practical standpoint, the liaison office is most useful where a foreign company wants to test the market, coordinate with local stakeholders, support headquarters, or build a foothold in Türkiye before deciding whether to establish a branch or subsidiary. Official guidance supports that reading because it specifically refers to liaison offices established for market research and promotion of foreign company products or services, while also making clear that those particular activity types do not qualify for extension of operating term. (Yatırım Ofisi)
For foreign investors, the attraction is clear. A liaison office can create lawful visibility and administrative presence in Türkiye without requiring the company to take on the full structure of a Turkish joint stock company or limited liability company. But the legal restrictions are equally important. The office exists only under license, only within declared activities, and only so long as the non-commercial character of its operations is preserved. (Yatırım Ofisi)
This guide explains liaison office setup in Turkey from both a legal and practical perspective. It covers what a liaison office is, what it cannot do, the required documents, licensing duration, extension limits, sector-specific review, post-license obligations, work permit issues, and the most common legal mistakes foreign companies make when choosing this route. (Yatırım Ofisi)
What Is a Liaison Office in Turkey?
A liaison office, sometimes called a representative office, is a locally licensed presence of a foreign company in Türkiye that is allowed to operate only on a non-commercial basis. Official Invest in Türkiye guidance states that the office may be established by a company incorporated under foreign law, but only after obtaining a license from the Ministry of Industry and Technology and only on the condition that the office does not engage in any commercial activities in Türkiye. (Yatırım Ofisi)
This means the liaison office is not a Turkish operating company. It is not a Turkish joint stock company, not a Turkish limited liability company, and not a branch that conducts the parent’s business directly. The defining legal idea is that the foreign company is allowed to maintain an official presence in Türkiye without converting that presence into an income-generating commercial establishment. That is why the office is usually chosen for preparatory, supportive, or representational functions rather than core commercial execution. (Yatırım Ofisi)
The legal regime is therefore permission-based rather than automatic. A foreign company cannot simply rent an office, put up a sign, and call it a liaison office. Official guidance requires a formal application to the Ministry of Industry and Technology’s General Directorate of Incentive Implementation and Foreign Investment (GDIIFI), supported by a specific document package and tied to declared activities. (Yatırım Ofisi)
The Core Legal Restriction: No Commercial Activity
The most important rule in Turkish liaison office law is the ban on commercial activity. Official guidance states this directly and treats it as a condition of the office’s existence. This rule should be understood broadly. The legal problem is not limited to large-scale sales activity. Any operating model that effectively turns the office into a revenue-generating local business platform risks falling outside the lawful scope of the liaison office regime. (Yatırım Ofisi)
That is why foreign companies must be careful at the planning stage. A liaison office can support market entry, but it cannot substitute for a branch or subsidiary where the real goal is to trade in Türkiye. If the business model requires invoicing customers, concluding ordinary commercial transactions locally, or carrying out business functions that go beyond non-commercial support, the foreign company should typically consider a Turkish subsidiary or branch instead. This is a practical inference from the official rule that the office must not engage in commercial activity. (Yatırım Ofisi)
The official guidance itself gives useful clues about practical boundaries. It specifically mentions offices licensed to conduct market research or promotion of foreign company products or services, and then states that the terms of operation of such offices shall not be extended. This confirms that these kinds of non-commercial promotional or exploratory functions do fall within the liaison-office framework, but also shows that Turkish authorities distinguish between temporary exploratory presence and longer-term institutional continuation. (Yatırım Ofisi)
Practical Use Cases for a Liaison Office
In practical terms, a liaison office is best understood as a bridge structure. It allows the foreign parent to establish visibility, collect market knowledge, coordinate with suppliers or professional advisers, and prepare for deeper market entry without immediately forming an operating company. Official Turkish guidance supports this view by recognizing market research and product-promotion activity within the liaison office framework. (Yatırım Ofisi)
A liaison office can therefore make sense where the foreign company is still evaluating whether Türkiye should become a full operating market. It can also be useful where the parent wants to supervise relationships, build a pipeline, or manage non-commercial support functions before deciding whether to create a branch or subsidiary. The key is that the office must remain faithful to its declared non-commercial nature. (Yatırım Ofisi)
The office may also serve as a structured way to maintain representation in Türkiye while centralizing contracts and revenue-generating functions abroad or in another group entity. But that model must be designed cautiously. The more the Turkish office begins to look like an operating sales or execution center, the greater the risk that the arrangement conflicts with the non-commercial rule. Again, this follows from the official licensing condition, even if the exact factual boundary must be assessed case by case. (Yatırım Ofisi)
Which Authority Handles Liaison Office Licensing?
Official Invest in Türkiye guidance states that liaison office establishment applications are submitted to the Ministry of Industry and Technology, specifically the General Directorate of Incentive Implementation and Foreign Investment (GDIIFI). The same guidance states that applications for establishment and term extension are concluded within fifteen working days from the date of application, provided that the requested information and documents are complete and accurate. (Yatırım Ofisi)
This is an important procedural point. Unlike company incorporation through Trade Registry Directorates and MERSIS, the liaison office route depends on an administrative licensing process handled by the Ministry. In other words, the foreign company should think of the liaison office not as a trade-registry filing only, but as a ministry-controlled permission regime with documentary review. (Yatırım Ofisi)
Required Documents for Liaison Office Setup in Turkey
Official Turkish guidance lists the core document package for establishing a liaison office. The application must include an application form, a statement outlining the works to be conducted by the liaison office, an undertaking that the office will not engage in commercial activities, and proof that the person signing that statement is fully authorized by the foreign company. These documents go directly to the legal heart of the process because they define both the office’s intended activity and the foreign company’s commitment to remain within lawful limits. (Yatırım Ofisi)
The document package must also include a certificate of activity issued in the foreign country and verified either by the relevant Turkish Consulate or in accordance with the Apostille Convention. Official guidance further requires either a certificate of activity issued to the foreign company or its balance sheet and income statement, which helps the Ministry assess the applicant’s corporate identity and operating reality. (Yatırım Ofisi)
In addition, the file must contain a certificate of authorization issued to the individual or individuals appointed to conduct the activities of the liaison office. If the setup procedures are handled by another representative, a power of attorney must also be submitted. Official guidance adds that if originals are submitted to GDIIFI, copies may be approved there and the originals returned to the applicant. (Yatırım Ofisi)
This document list shows that liaison office setup is not informal. Even though the office is non-commercial, the Turkish authorities still require clear proof of the foreign company’s legal existence, the office’s intended function, and the authority of the people acting for the applicant. (Yatırım Ofisi)
Apostille and Document Formalities
Cross-border formality is one of the areas where applicants most often make mistakes. Official guidance states that the certificate of activity from the foreign country must be verified either by the relevant Turkish Consulate or under the Hague Apostille Convention. That means foreign-origin documents cannot simply be attached in ordinary copy form. (Yatırım Ofisi)
This requirement is legally significant because the liaison office regime is permission-based. If the core foreign corporate documents are not properly legalized or verified, the application may fail or be delayed even if the office’s intended activity is perfectly lawful. In practice, foreign companies should build in enough time for apostille, consular authentication where relevant, translation, and internal signature coordination before filing in Türkiye. (Yatırım Ofisi)
Initial License Duration
Official Invest in Türkiye guidance states that, during the initial application for liaison offices, licenses are granted for a maximum of three years within the scope of the declared activities. This is one of the key features that distinguishes liaison offices from Turkish companies and branches. The office is not created as a perpetual open-ended structure by default. It begins with a time-limited administrative authorization. (Yatırım Ofisi)
This time limit matters strategically. A foreign company choosing the liaison-office route should do so with a realistic short- to medium-term plan. If the company expects a temporary exploratory phase, the three-year maximum may be entirely suitable. If the company is already certain that it needs a durable operating structure for business execution in Türkiye, a subsidiary or branch may be more appropriate from the outset. (Yatırım Ofisi)
Extension of the Operating Term
A liaison office can seek an extension, but not automatically. Official Turkish guidance states that liaison offices wishing to extend their term of operation must apply to GDIIFI before the expiration of the current operating term. The same guidance states that GDIIFI may assess extension applications based on the nature of the office’s activities during the previous year, the business plan, the company’s future objectives in Türkiye, the existing and anticipated amount of expenditure, and the number of employees. (Yatırım Ofisi)
This is important because extension is framed as a substantive review, not a routine administrative renewal. The foreign company should therefore maintain a consistent activity profile and documentary trail showing that the office has remained within its declared non-commercial scope and still serves a legitimate purpose in Türkiye. (Yatırım Ofisi)
Official guidance also states that the operating term of offices licensed to conduct market research or promotion of foreign company products or services shall not be extended. This is one of the most practically significant rules in the entire liaison office regime. It means that some of the most common entry-level liaison office functions are treated as inherently temporary. Foreign companies using the office for these purposes should therefore plan for transition rather than assume indefinite continuation. (Yatırım Ofisi)
Sector-Specific Review and Regulated Activities
Not every liaison office application is handled in the same way. Official Invest in Türkiye guidance states that foreign companies seeking to set up liaison offices to conduct financial activities subject to special legislation, such as money and capital markets or insurance, will have their applications evaluated by the relevant competent agencies, including the Capital Markets Board of Türkiye and the Banking Regulation and Supervision Agency. (Yatırım Ofisi)
The same official guidance also states that, in other industries requiring licenses or similar authorizations, the Ministry may conclude applications after consulting the competent authorities that are duly authorized to issue those permits or licenses. This means that even in the liaison-office context, sector regulation still matters. A foreign company in a regulated field should not assume that the general document list is the whole story. (Yatırım Ofisi)
Post-License Obligations
The post-license stage is often overlooked, but it is legally important. Official guidance states that copies of the tax registration and the tenancy agreement for the liaison office must be submitted to GDIIFI within a maximum of one month. This shows that licensing is not the final administrative act; the office must still complete local setup and report it back to the Ministry. (Yatırım Ofisi)
The same guidance states that liaison offices must notify GDIIFI within one month of any changes concerning the office representative or the foreign company’s title. If the office address changes, the office must produce a new tenancy agreement reflecting the new address. If the representative changes, a new certificate of authorization is required. These rules confirm that Turkish authorities expect ongoing administrative accuracy, not just correct information on day one. (Yatırım Ofisi)
Termination of Operations
Official Invest in Türkiye guidance also regulates the end of the office’s life. If a liaison office terminates its operations, it must furnish GDIIFI with a statement of termination obtained from the relevant tax office. The same guidance adds that offices may not claim transfers of funds except for balances that remain outstanding upon termination and liquidation. (Yatırım Ofisi)
This is an important closure rule because it shows that liaison office operations are integrated into Turkish administrative supervision from beginning to end. Termination is not just a matter of locking the office door or surrendering the lease. It requires formal closure evidence from the tax side and proper notification to the Ministry. (Yatırım Ofisi)
Work Permits and Personnel Issues
Foreign companies often ask whether they can assign foreign staff to a liaison office. Official Invest in Türkiye’s work permit guidance states that every foreigner intending to work in Türkiye must obtain a work permit. More specifically, it states that the Ministry of Labor and Social Security may grant work permits to a maximum of one foreigner holding an authorization certificate to work in the liaison offices of enterprises falling within the scope of Qualified Foreign Direct Investment, provided that the liaison office has obtained an operating license from the Ministry of Industry and Technology and only for the duration of its activities. (Yatırım Ofisi)
The same official page also refers to a maximum of one person at liaison offices issued an authorization certificate by the overseas parent company in the context of foreign key personnel. This is a practical caution point. A foreign company should not assume that a liaison office can be staffed freely with multiple foreign employees. The work-permit regime is restrictive and tied to both qualification status and office authorization. (Yatırım Ofisi)
This does not mean the office cannot function. It means personnel planning should be done carefully and lawfully, with a clear distinction between Turkish-resident local staffing and foreign-national work authorization. A liaison office that ignores work-permit rules may create immigration and labor-law risk even if its commercial-scope rules are respected. (Yatırım Ofisi)
Timeline and Administrative Efficiency
Official Turkish guidance states that establishment and extension applications are concluded within fifteen working days, provided the information and documents are complete and accurate. This is relatively efficient on paper, but the practical duration will depend heavily on document quality, legalization, internal corporate authorization, and whether sector-specific consultation is required. (Yatırım Ofisi)
For that reason, the smartest practical approach is to treat the official fifteen-working-day period as the Ministry’s review window once the file is properly ready, not as the entire project timeline from zero. The preparatory stage abroad is often where the real timing risk sits. (Yatırım Ofisi)
Common Mistakes in Liaison Office Setup
The most common mistake is choosing a liaison office when the real business plan requires commercial operations. Official guidance is unambiguous that the office must not engage in commercial activities in Türkiye. A company that actually needs local selling, contracting, or operating capability should not use the liaison-office regime as a shortcut. (Yatırım Ofisi)
A second common mistake is assuming the office can be extended indefinitely. Official guidance clearly states that initial licenses are for a maximum of three years and that offices licensed for market research or promotion are not eligible for extension. Businesses that choose those categories should plan for a later structural decision rather than rely on renewal. (Yatırım Ofisi)
A third mistake is underestimating post-license compliance. Copies of the tax registration and tenancy agreement must be submitted within one month, and changes in representative or foreign company title must also be notified within one month. A company that gets the license but neglects the follow-up obligations leaves itself exposed to avoidable administrative problems. (Yatırım Ofisi)
A fourth mistake is poor staffing assumptions. The work-permit framework for foreigners in liaison offices is narrow, and official guidance indicates a maximum of one foreigner in qualifying cases. Companies that assume they can freely transfer foreign staff into a liaison office often discover that Turkish labor authorization is a separate constraint. (Yatırım Ofisi)
Conclusion
Liaison office setup in Turkey is a practical legal tool for foreign companies that want a structured, licensed, and non-commercial presence in Türkiye. It is especially useful for exploratory, promotional, and representational functions, but it exists under a strict rule: the office must not engage in commercial activities in Türkiye. That is the foundation of the regime and the key distinction between a liaison office and a Turkish subsidiary or branch. (Yatırım Ofisi)
The process is document-based and ministry-led. The foreign company must apply to the Ministry of Industry and Technology, submit the prescribed documents, respect apostille or consular formalities, define its activities clearly, and understand that the initial license is granted for a maximum of three years. Extension is possible in some cases, but not for offices licensed for market research or product promotion. (Yatırım Ofisi)
For many foreign businesses, the liaison office works best as a temporary and strategic presence, not as a substitute for a real operating entity. Used correctly, it can help a company learn the Turkish market, coordinate locally, and prepare for deeper investment. Used incorrectly, it can create regulatory risk by placing commercial reality inside a non-commercial legal shell. That is why the best legal approach is to match the structure to the business plan from the beginning. (Yatırım Ofisi)
