Company Formation in Turkey: Practical Guide

Joint Stock Company (Anonim Şirket - A.Ş.)

The Joint Stock Company is favored by institutional investors, large-scale industrial projects, holding structures, and companies that plan to raise external capital or execute future equity divestments. An A.Ş. may also be founded with a single shareholder. A primary advantage is the protection of shareholders from public debts; only the board members with statutory management authority are held accountable for uncollected tax and social security obligations.

Equity transfers in an A.Ş. do not require notarization, trade registry publication, or general assembly consent unless restricted by custom provisions in the articles of association. Furthermore, share transfers executed through physical share certificates benefit from significant capital gains tax exemptions under specific holding-period conditions governed by Turkish tax legislation. A board of directors governs the entity, and board meetings can be conducted electronically.

Branch Office (Şube)

A foreign parent company can establish a registered branch in Türkiye to conduct commercial activities under the direct identity of the home entity. A branch does not possess separate legal personality; all liabilities and financial commitments attach directly to the foreign parent company. The branch must bear the full commercial name of the parent company along with its geographic location in Türkiye, and an authorized commercial representative residing in Türkiye must be appointed via power of attorney.

Liaison Office (İrtibat Bürosu)

Companies wishing to assess the Turkish market without engaging in commercial transactions can apply to establish a liaison office, also known as a representative office. Regulated directly by the Ministry of Industry and Technology, liaison offices are strictly prohibited from generating revenue, executing commercial sales, or issuing invoices. Their permitted activities are restricted to market research, technical feasibility studies, regional coordination, and supplier evaluation. All operational expenses of a liaison office must be funded entirely from overseas funds transferred into Türkiye in foreign currency.

Prerequisites and Documentation for Foreign Investors

Preparation of corporate documentation represents the most time-consuming phase of company formation. Any document issued outside Türkiye must satisfy formal legalization procedures before acceptance by the trade registry.

Required Foreign Documents

When the foreign founding party is a corporate entity, the trade registry requires evidence of active legal status and corporate authorization. This typically includes an official certificate of good standing or certificate of incorporation, authenticated articles of association, a board resolution authorizing the establishment of the Turkish entity and appointing legal signatories, and signature declarations of designated managers.

All documents executed outside Türkiye must either bear an Apostille pursuant to the Hague Apostille Convention or be authenticated by the Turkish consulate located in the country of issuance. Once in Türkiye, these legalized documents must be officially translated into Turkish by a sworn translator and notarized by a Turkish notary public.

Tax Identification and Power of Attorney

Every foreign shareholder and non-resident director must obtain a potential Turkish tax identification number from the local tax administration prior to corporate filing. This number is necessary to process filings in MERSİS and open pre-incorporation bank accounts. Foreign founders commonly issue a specialized power of attorney to a local legal or corporate representative to execute the MERSİS submission, sign company formation documentation, liaise with chambers of commerce, and collect official registry declarations without requiring physical travel during preliminary steps.

The Step-by-Step Incorporation Process

The operational formation of a Turkish company follows a structured sequence through digital and physical regulatory touchpoints.

Step 1: Drafting the Articles of Association and MERSİS Entry

The incorporation process begins on the Central Commercial Registration System (MERSİS), an electronic portal administered by the Ministry of Trade. The company's basic constitutional parameters are entered online: commercial trade name, registered corporate address, corporate objectives and scope of activity (purpose clause), management structure, initial capital amounts, and representation rules. The trade name must be unique and cannot include restricted terms without formal statutory authorization.

Step 2: Capital Deposit and Competition Authority Payment

The Turkish Commercial Code sets minimum capital requirements for both Ltd. Şti. and A.Ş. entities. While requirements differ between the two structures, founders of a Joint Stock Company are legally required to deposit at least twenty-five percent of the subscribed share capital into a temporary corporate bank account prior to registration. The remainder can generally be paid within a statutory timeframe following incorporation.

For a Limited Liability Company, statutory amendments allow founders to deposit the full capital within twenty-four months following incorporation, unless specific regulated sectors demand prior blocked deposits. Regardless of the company type, a statutory fee equal to a fraction of a percent of the total committed share capital must be paid to the account of the Turkish Competition Authority before final filing.

Step 3: Execution of Signatures and Trade Registry Submission

Once the MERSİS application is accepted and an appointment is scheduled, authorized signatories or their appointed attorneys attend the Trade Registry Office at the relevant Chamber of Commerce (such as the Istanbul Chamber of Commerce or Ankara Chamber of Commerce). The articles of association and signature declarations of company managers are formally executed and authenticated. Upon submission of all apostilled foreign documents, lease contracts, and capital payment receipts, the trade registry reviews the complete dossier.

Step 4: Registration and Announcement

Upon satisfactory review, the trade registry finalizes the incorporation, assigns the company its commercial registration number, and prepares the official establishment announcement. Legal personality is officially acquired on the date the registration is approved. The announcement is subsequently published in the Turkish Trade Registry Gazette (Türkiye Ticaret Sicili Gazetesi), creating public notice of corporate existence and management powers.

Post-Incorporation Compliance and Operational Setup

Registering with the Trade Registry marks the birth of the legal entity, but several compulsory operational steps must follow immediately before regular business can be conducted.

Signature Circular (İmza Sirküleri)

Immediately after trade registry registration, the designated company managers must appear before a Turkish notary public to issue a signature circular. This document serves as definitive legal proof of who has the authority to represent, bind, and execute contracts on behalf of the newly created entity. Without a valid signature circular, the company cannot execute commercial contracts, open full operational bank accounts, or register for utilities.

Tax Office Registration and Physical Site Inspection (Yoklama)

The Trade Registry electronically notifies the local Tax Office (Vergi Dairesi) upon completed registration. However, company management or an authorized certified public accountant (Mali Müşavir) must submit initial notifications, registered lease agreements, and corporate documentation to complete tax activation. The tax office will then dispatch a tax inspector to conduct an unannounced or scheduled physical inspection (yoklama) of the company's registered head office address.

The inspector verifies that the company maintains an actual physical operational presence, inspects signage and lease agreements, checks the presence of office equipment, and issues an inspection report signed by the company representative. A successful inspection confirms tax registration and enables the issuance of the corporate tax plate (vergi levhası).

Social Security and Mandatory Professional Affiliations

If the company intends to employ personnel immediately, it must open an employer registration file with the Social Security Institution (SGK) before any employee starts work. Furthermore, every commercial company in Türkiye is required by law to maintain active membership in the relevant chamber of commerce or chamber of industry where it is incorporated, paying mandatory annual dues determined by operational scale and registered capital.

Corporate Banking for Foreign-Owned Companies

Opening an active corporate bank account remains one of the most operationally challenging steps for foreign-owned Turkish entities due to global anti-money laundering (AML), Know Your Customer (KYC), and Common Reporting Standard (CRS) mandates enforced by Turkish commercial banks.

Banks require thorough verification of the Ultimate Beneficial Ownership (UBO) structure down to individual natural persons holding significant direct or indirect equity stakes. If a foreign parent company is held by trusts, nominee arrangements, or entities incorporated in non-transparent jurisdictions, Turkish banks conduct extensive compliance evaluations that can lengthen onboarding timelines.

To expedite account activation, foreign businesses must prepare comprehensive UBO declarations accompanied by notarized share ledgers, clear organograms showing corporate hierarchy, and direct contact details of directors. While some preliminary procedures can be handled by legal representatives, bank compliance officers frequently mandate the physical presence of the authorized company manager at the local bank branch to execute signature cards and satisfy direct KYC checks.

Practical Company Formation Checklist

5. Obtain potential Turkish tax numbers for all non-resident shareholders and appointed foreign managers.
6. Submit draft articles and corporate parameters through the MERSİS digital portal to generate tracking numbers and schedule the trade registry appointment.
7. Pay the mandatory Competition Authority statutory fee and deposit any mandatory initial capital share into a blocked corporate bank account.
8. Execute incorporation documents and signature declarations at the local Chamber of Commerce Trade Registry Office.
9. Obtain the official Trade Registry registration approval, registry extract, and formal publication in the Turkish Trade Registry Gazette.
10. Notarize company management signature circulars and mandatory commercial accounting books before a Turkish notary public.

Common Mistakes Foreign Companies Make

Navigating an unfamiliar legal and administrative ecosystem can lead to operational delays and unexpected tax liabilities if foundational requirements are overlooked.

Defining an Overly Restrictive Purpose Clause

Under Turkish corporate practice, a company's capacity to execute certain transactions, apply for specific licenses, or clear goods through customs can be delayed if its registered scope of activity (purpose clause) is drafted too narrowly. While the ultra vires doctrine has been moderated under modern corporate statutes, public institutions, banks, and customs authorities regularly inspect the registered commercial objectives. Omitting secondary trading activities or logistics scopes from the articles of association can necessitate costly amendments, shareholder meetings, and trade registry re-filings later on.

Underestimating Public Debt Liability in an Ltd. Şti.

Many foreign executives default to forming a Limited Liability Company assuming corporate liability functions identically to Western limited partnerships or Anglo-American LLCs. In Türkiye, shareholders and statutory managers of an Ltd. Şti. bear personal, non-delegable liability for unpaid public debts—including corporate income tax, withholding taxes, value-added tax (VAT), and social security arrears. If the company becomes insolvent with unpaid public liabilities, authorities can seek recovery directly from shareholders' personal assets in proportion to their equity. Investors seeking strict public debt insulation frequently prefer a Joint Stock Company (A.Ş.) structure instead.

Using Incompatible Virtual Office Providers

While virtual offices are legal and commonly utilized for holding entities or remote service providers, using an unvetted virtual office provider with poor regulatory compliance can trigger immediate rejection during the mandatory tax office site inspection (yoklama). If a tax inspector arrives and finds no operational desk, no signage, no forwarding system, or no responsive representative, the tax office may flag the company as inactive or fictitious. This results in the suspension of tax numbers and an inability to issue commercial invoices.

Failing to Retain a Certified Public Accountant

Turkish tax law mandates that corporate accounting records and statutory tax returns must be maintained, reviewed, and electronically submitted by an independent certified public accountant (Serbest Muhasebeci Mali Müşavir - SMMM). Foreign founders sometimes postpone contracting an accountant until after commercial launch. This creates non-compliance immediately, as statutory monthly filings, withholdings, and payroll declarations commence immediately upon incorporation, irrespective of whether trading activity has begun.
