Sector-specific restrictions in Turkish company formation law can affect foreign ownership, board composition, licensing, share transfers, and articles of association. This guide explains how regulated sectors such as broadcasting, maritime, civil aviation, finance, insurance, and capital markets are treated under Turkish law.
Introduction
Sector-specific restrictions in Turkish company formation law are one of the most important issues for founders, foreign investors, and corporate groups entering Türkiye. The general rule in Turkish company law is relatively liberal: official investment guidance states that international investors may establish any form of company recognized by the Turkish Commercial Code and that the business environment is designed to facilitate investment through a one-stop-shop registration model. At the same time, the same official source expressly states that there are no restrictions on the nationality of shareholders and those holding management rights except for specific sectors such as TV broadcasting, maritime, and civil aviation. That sentence is the key starting point for any serious legal analysis of sector-based formation limits in Turkey. (Türkiye Yatırım Ofisi)
The practical problem is that many investors understand “sector restriction” too narrowly. In Turkish law, a sector-specific restriction does not always mean a complete ban on foreign ownership. Sometimes it means a foreign-shareholding ceiling. Sometimes it means a Turkish-control or Turkish-board-majority rule. Sometimes it means the company can be formed only with prior approval from a sector regulator and the Ministry of Trade. In other cases, it means the company’s articles of association must be drafted within a narrower activity scope, or that later share transfers and amendments require official permission. So the real legal question is not simply whether a foreigner can own shares, but what kind of company can be formed, under what governance structure, with which approvals, and for which business scope. (https://ticaret.gov.tr)
This distinction matters even more because Turkish formation law is highly structured. Official Invest in Türkiye guidance states that company establishment is carried out through Trade Registry Directorates and MERSIS, but highly regulated sectors do not move through that route in a purely ordinary way. The Ministry of Trade’s official list of companies subject to ministry permission shows that, in a wide range of regulated sectors, incorporation and amendments to the articles of association require advance approval from the Ministry and often from the competent sector regulator as well. In other words, sector-specific restrictions in Turkey often operate through formation procedure, not only through substantive activity rules. (Türkiye Yatırım Ofisi)
This article explains sector-specific restrictions in Turkish company formation law from a practical and investor-oriented perspective. It focuses on the sectors that matter most in real transactions: broadcasting, civil aviation, maritime, banking and financial services, insurance, capital markets, foreign-exchange institutions, free zones, technology development zone management companies, and other ministry-permission sectors. It also explains how founders should think about these rules when choosing a company type, drafting the articles of association, negotiating share transfers, and planning cross-border structures. (https://ticaret.gov.tr)
The Baseline Rule: Broad Openness, Narrow but Important Exceptions
The baseline legal position in Turkey is openness. Official Invest in Türkiye guidance states that international investors have the same rights and liabilities as local investors, that the conditions for setting up a business and transferring shares are the same as those applied domestically, and that the Turkish Commercial Code provides the basic corporate framework for company formation. That general rule is one reason Turkey remains attractive for foreign investors forming subsidiaries, joint ventures, and wholly owned operating companies. (Türkiye Yatırım Ofisi)
But the same official source immediately narrows that openness by identifying the three classic exception sectors: TV broadcasting, maritime, and civil aviation. This is important because it means a founder should not assume that the usual “100 percent foreign-owned LLC or JSC” model will always work in every regulated industry. In some sectors, the issue is not whether the investor can use a Turkish company at all, but whether the investor can satisfy the sector’s additional nationality, control, flag, or operating-license conditions. (Türkiye Yatırım Ofisi)
A second major layer of exception comes from sectors that are not necessarily closed to foreign capital, but are formation-restricted because they require prior administrative approval. The Ministry of Trade’s official page on companies subject to ministry permission shows that this category includes banks, financial leasing companies, factoring companies, financing companies, consumer-finance and card-services companies, asset-management companies, insurance companies, holdings, authorized foreign-exchange institutions, public warehousing companies, licensed warehousing companies, product-specialized exchange companies, independent audit companies, international surveillance companies, technology development zone management companies, free-zone founder/operator companies, portfolio management companies, brokerage firms, and investment companies. (https://ticaret.gov.tr)
That means the correct legal map is not simply “restricted sectors” versus “unrestricted sectors.” It is more accurate to think in three layers: first, sectors that are broadly open under ordinary company law; second, sectors with foreign ownership or Turkish-control limits; and third, sectors where company formation or charter amendments are permission-based, even if foreign investment is not categorically barred. This layered analysis is what makes Turkish sector-specific formation law manageable in practice. (Türkiye Yatırım Ofisi)
Broad Formation Restrictions Versus Narrow Corporate Restrictions
One of the most common legal misunderstandings is to treat sector-specific restrictions as if they all look the same. They do not. In Turkey, some restrictions apply at the level of the company form itself. Others apply at the level of the ownership structure, the board composition, the company’s business object, or the need for a specific license before or after incorporation. This distinction matters because the legal solution depends on where the restriction sits. (https://ticaret.gov.tr)
For example, in some sectors the foreign investor may be free to incorporate an ordinary Turkish company, but the company cannot begin regulated activity until the relevant regulator authorizes it. In other sectors, the regulator’s approval is required already at the formation and articles-amendment stage. In civil aviation, the rules go even further by regulating share structure, board composition, voting control, and even the scope clause of the company agreement. This is why sector-specific legal diligence in Turkey should begin before MERSIS drafting, not after. (https://ticaret.gov.tr)
This also explains why founders should not look only at the Turkish Commercial Code when entering a regulated sector. The Code is the general company-law platform, but sector-specific statutes, regulations, and regulator-issued procedures can override the practical formation route for the relevant activity. In Turkey, “company formation law” in a regulated sector often means reading company law together with regulatory law. (Türkiye Yatırım Ofisi)
TV Broadcasting: Foreign Capital Is Allowed, but Capped
Broadcasting is one of the clearest sectors where Turkish law imposes a specific foreign-investment limit. Official RTÜK material explaining Law No. 6112 states that the foreign capital ratio in broadcasting companies was increased from 25 percent to 50 percent. That means Turkish broadcasting law does not exclude foreign investment entirely, but it does not treat the sector as fully open either. For company-formation purposes, this matters because the ownership structure of a media service provider must be compatible with the statutory foreign-capital ceiling from the outset. (RTÜK)
This broadcasting example is legally important for two reasons. First, it shows that a sector-specific restriction can be expressed as a cap, not a prohibition. Second, it shows that the restriction is not merely a licensing afterthought. If the company is formed in a way that ignores the foreign-capital rule, the structure itself becomes vulnerable. In practical transaction work, that means shareholder agreements, capital increases, share transfers, and indirect holding structures in the broadcasting space must be tested against the statutory percentage rule before closing, not after. (RTÜK)
Broadcasting also illustrates a broader Turkish pattern: the state often uses sector-specific corporate rules not just to regulate content or operations, but to shape the ownership architecture of the license-holding entity itself. For investors, the message is clear: if the target sector is media, formation law and licensing law are inseparable. (RTÜK)
Civil Aviation: Turkish Control Is a Formation-Level Requirement
Civil aviation is one of the most heavily structured sectors from a company-formation perspective. The Directorate General of Civil Aviation’s SHY-6A regulation states that companies carrying out commercial air transport must have their commercial centers in Türkiye. It also requires, for commercial air transport operators, that at least 51 percent of the shares be registered shares, and that the majority of shares, the majority of voting rights, the majority of board members, and control be held by Turkish-citizen shareholders. For listed companies, the wording is adapted, but the majority of the non-floated registered shares and the majority of representation and management authority must still remain with Turkish citizens.
These rules are not merely operating-license rules in the abstract. They directly affect how the company must be formed. A foreign investor cannot simply set up an ordinary airline company in Turkey with unrestricted foreign control and then try to regularize the position later. The ownership structure, voting control, board composition, and commercial center must already comply with the aviation framework when the company seeks authorization. This makes civil aviation one of the clearest examples of a sector where company formation law is substantively shaped by sector regulation.
The aviation regime also restricts later corporate transactions. SHY-6A states that, before any transfer of existing registered shares, any increase in an existing shareholder’s stake, or any public offering of shares, companies that have already obtained pre-approval or an operating license must obtain prior permission from the DGCA. The same regulation also allows the authority to examine indirect ownership structures all the way through the chain until real persons are reached. In practice, this means aviation restrictions are not only formation restrictions; they are also ongoing share-transfer and control restrictions.
A further company-formation restriction in aviation concerns the purpose clause. SHY-6A states that, for operators carrying only cargo or carrying passengers with aircraft having twenty or more seats, the “purpose and subject” section of the company contract may not include business fields other than aviation and aviation-related work. This is a striking example of a sector where the regulator is not satisfied by ordinary commercial flexibility. The charter itself must be drafted in a sector-specific way.
Maritime: Restrictions Often Operate Through Flag, Registry, and Cabotage
Maritime is one of the three sectors expressly identified by Invest in Türkiye as an exception to the general rule of unrestricted shareholder nationality. Unlike broadcasting, however, the restriction is often not expressed primarily as a single foreign-capital percentage. Instead, Turkish maritime law frequently operates through flag, registry, and route authorization rules tied to domestic maritime activity. (Türkiye Yatırım Ofisi)
A current official example appears in the 2025 Regulation on Regular Voyages by Ships. The Ministry’s regulation states that vessels conducting regular voyages between Turkish coastal facilities must obtain route permission from the administration and must be registered either in the National Ship Registry or the Turkish International Ship Registry. The same regulation also allows the administration to limit routes and vessel capacities in the public interest and for sustainable competition. This shows that, in maritime, restrictions may appear as company-plus-vessel eligibility rules rather than simple shareholder caps.
From a formation-law perspective, this means that a foreign investor entering maritime transport in Türkiye should not ask only, “Can I own the Turkish company?” The correct question is broader: “Will the company’s vessels, route structure, and operating permissions satisfy the rules applicable to the specific coastal or international maritime activity?” In some cases, the answer will turn more on flag and registry structure than on a simple reading of the shareholding table.
This is also why maritime restrictions are often underestimated in company formation work. They do not always show up in the articles of association alone. They show up in the intersection of the company, the ship registry, the route permit, and the type of domestic maritime activity being performed.
Finance, Insurance, and Capital Markets: Approval-Based Formation Restrictions
A second major cluster of sector-specific restrictions in Turkey does not work through nationality caps but through regulator-gated incorporation. The Ministry of Trade’s official list states that banks require both BRSA approval and Ministry permission for incorporation and all charter amendments. The same page says the same for financial leasing, factoring, financing, and asset-management companies, while insurance companies require the favorable opinion of the Ministry of Treasury and Finance in addition to Ministry permission. (https://ticaret.gov.tr)
Capital-markets institutions are regulated similarly. The Ministry’s page states that portfolio management companies, brokerage firms, and different types of investment companies are subject to Capital Markets Board approval for incorporation and charter amendments, and also need Ministry permission. This means that, even if a foreign investor is theoretically allowed to participate in the capital of such an entity, incorporation is still not an ordinary trade-registry-only process. (https://ticaret.gov.tr)
The same pattern appears in other finance-adjacent sectors. Consumer-finance and card-services companies, authorized foreign-exchange institutions, and certain other regulated financial businesses are also listed on the Ministry’s permission page. In the case of authorized foreign-exchange institutions, the Ministry’s page is especially noteworthy because it states that not only incorporation and charter amendments, but even share transfers causing changes in shareholders are subject to Treasury/Finance approval, and every charter amendment additionally requires Ministry permission. (https://ticaret.gov.tr)
The practical consequence is that sector-specific restriction in finance often means procedural restriction. The company may be formed only after the relevant regulator is satisfied with ownership, capital, governance, and activity conditions, and later amendments are not simply internal company decisions. They are external approval events. (https://ticaret.gov.tr)
Other Ministry-Permission Sectors Founders Commonly Overlook
Not every restricted sector is intuitively “financial” or “sensitive.” The Ministry of Trade’s official list also includes holdings, public warehousing companies, licensed warehousing companies, product-specialized exchange companies, independent audit companies, international surveillance companies, technology development zone management companies, and free-zone founder/operator companies. Some of these require another ministry’s or authority’s permission in addition to Ministry permission. For example, technology development zone management companies require permission from the Ministry of Industry and Technology, and free-zone founder/operator companies require presidential permission in addition to Ministry approval. (https://ticaret.gov.tr)
This is a good example of why founders should not equate “regulated sector” only with banking or broadcasting. A company can be entirely commercial and still fall into a permission-based formation category because of the public-interest or infrastructure role of its activity. The mistake in practice is often not that the founders knowingly violate a restriction, but that they do not realize the sector is permission-based until the file is already prepared and the transaction timetable is fixed. (https://ticaret.gov.tr)
Holding companies deserve special mention because many foreign groups use Turkish holdings for group structuring and assume a standard JSC is enough. The Ministry’s page expressly states that holdings are among the companies whose incorporation and charter amendments require Ministry permission. So even where the holding is not itself a regulated financial institution, its formation path is not identical to that of an ordinary industrial or trading JSC. (https://ticaret.gov.tr)
Sector Restrictions Often Continue After Formation
A major practical point is that sector-specific restrictions in Turkey usually do not end once the company is incorporated. In aviation, the DGCA regulation requires permission not only at the authorization stage but also before certain share transfers, public offerings, and governance changes. The regulation also requires notification of board-member changes and allows the authority to suspend or revoke operations if the ownership or governance structure falls out of compliance.
In broadcasting, the foreign-capital ceiling affects not just day-one incorporation but also later investment rounds, share transfers, and indirect control arrangements. In foreign-exchange institutions, the Ministry’s page explicitly says that share transfers causing changes in shareholders require approval. In Ministry-permission companies more generally, charter amendments remain approval-sensitive. This means that the “restriction” is not a one-time gate; it is part of the company’s continuing legal environment. (RTÜK)
For investors and transaction counsel, this is one of the most important due-diligence points. A company may have been validly formed years earlier and still become problematic if a later share transfer, capital increase, board change, or article amendment was implemented without the approvals required by the relevant sector regime. (https://ticaret.gov.tr)
Drafting Consequences: Articles of Association Must Match the Sector
Sector-specific restrictions in Turkey affect not only ownership but also charter drafting. The clearest example is aviation, where SHY-6A requires certain air-transport companies to keep their company-purpose clause limited to aviation and aviation-related work. That is a direct intervention in the articles of association.
But the same logic applies more broadly. If a company is in a ministry-permission sector, the charter should be drafted on the assumption that it will be scrutinized not only for general TCC compliance but also for sector compatibility. In regulated finance, insurance, capital markets, and infrastructure-like sectors, founders should expect the regulator to care about business scope, capital structure, representation, and sometimes special governance wording. (https://ticaret.gov.tr)
This is why sector-specific company formation work in Turkey should not be approached with a generic template. A charter that is perfectly fine for an ordinary LLC or JSC may be non-compliant or commercially unusable in a restricted sector. The safest drafting method is to treat the sector rule as part of the company law file from the beginning. (https://ticaret.gov.tr)
Practical Mistakes Founders Make
The first common mistake is assuming that the general Turkish rule of openness eliminates all sector-specific limits. Official Invest in Türkiye guidance says the opposite: TV broadcasting, maritime, and civil aviation remain exceptions to the ordinary rule on shareholder nationality and management rights. (Türkiye Yatırım Ofisi)
The second mistake is focusing only on foreign ownership percentages and ignoring other forms of restriction. Aviation shows that a sector can be restrictive even where the issue is not simply the percentage of foreign capital, but also the majority of voting rights, board composition, control, business scope, and pre-approval of share transfers.
The third mistake is treating ministry-permission sectors as if they were ordinary MERSIS filings. The Ministry of Trade’s official list shows that many sectors require both sector-regulator approval and Ministry permission for incorporation and charter amendments. A founder who discovers that only after preparing the whole file usually loses time and money. (https://ticaret.gov.tr)
The fourth mistake is thinking that once the company is incorporated, the restrictions disappear. In many sectors they do not. They continue to affect amendments, share transfers, board changes, public offerings, and operating authorizations. (https://ticaret.gov.tr)
Conclusion
Sector-specific restrictions in Turkish company formation law are best understood as a set of targeted exceptions layered onto a generally open corporate regime. Turkey broadly allows foreign investors to use ordinary company forms under the Turkish Commercial Code, but official sources make clear that exceptions exist in TV broadcasting, maritime, and civil aviation, and that many other sectors are subject to permission-based incorporation and charter-amendment rules. (Türkiye Yatırım Ofisi)
The practical lesson is that “restriction” in Turkey can mean several different things: a foreign-capital cap, a Turkish-control rule, a flag or registry requirement, a mandatory commercial-center rule, a narrow purpose clause, a prior approval requirement, or an ongoing share-transfer control. In regulated sectors, formation law is not just about filing a company; it is about fitting the company into the regulator’s view of who may own, govern, and operate the relevant activity. (RTÜK)
That is why the safest way to form a company in a regulated Turkish sector is to do sector analysis before MERSIS drafting, not after. Once the foreign-ownership rule, ministry-permission status, regulator approval path, and charter consequences are mapped correctly, Turkish sector-specific formation law becomes manageable. But when founders assume that every business can be formed like an ordinary trading company, the regulatory problems usually begin before the company even starts operating. (Türkiye Yatırım Ofisi)
