15/07/2026

With its dynamic market structure and strategic location, Turkey offers attractive business opportunities in Turkey for foreigners and local entrepreneurs alike who wish to experience establishing a business in Turkey. From the initial concept phase to active commercial operations, the most critical step in this journey is setting up a solid legal infrastructure. To open a company in Turkey, both domestic and international investors must navigate specific legal procedures and administrative regulations. Managing this process without errors legalizes and secures the enterprise while preventing potential administrative risks in the future.

For entrepreneurs who want to secure a legal status and start a business in Turkey, it is mandatory to meticulously compile the complete list of required documents requested by official institutions. Proper document management and strategic planning minimize the time and financial losses often encountered during company registration procedures. There are different legal structures available in the Turkey company register; these are joint-stock companies, limited liability companies, and sole proprietorships. To register company Turkey files correctly, you must gather the specific documents designated for each corporate structure during the application phase.

Required Documents for Joint-Stock Company (A.Ş.) Formation in Turkey

For entrepreneurs aiming to conduct large-scale projects and scale through future public offerings, pursuing a joint-stock company formation in Turkey is the most ideal option. The specific document dossier required for this corporate structure includes:

  • Articles of Association: The official corporate charter prepared electronically via MERSİS, signed by the founders, and approved in the presence of the Trade Registry Directorate.
  • Capital Blockage Letter: A formal bank letter demonstrating that at least 25% of the committed cash capital has been deposited into a corporate bank account and blocked. (According to the current 2026 regulations, the minimum capital requirement for a joint-stock company is 250,000 TL).
  • Cash Capital Payment Receipt: The wet-signed or digitally verifiable bank duplicate/receipt representing the blocked capital amount.
  • Signature Declaration: Certified signature declarations prepared in compliance with trade registry guidelines for individuals authorized to represent and bind the company.
  • Chamber of Commerce Registration Form: The official registration form containing the photographs and signatures of the founders, to be submitted to the relevant Chamber of Commerce.

H3: Required Documents for Limited Liability Company (LTD. ŞTİ.) Formation in Turkey

As one of the most preferred corporate structures for a company registration in Turkey, a limited liability company offers great advantages, as the partners’ liabilities are limited strictly to their capital shares. To successfully complete this type of company formation in Turkey, the following documents must be present in the dossier:

  • Articles of Association: The official contract approved on the MERSİS system, clearly stating the partners’ share ratios, corporate title, scope of activity, and headquarters address.
  • Managers’ Signature Declarations: Certified signature declarations executed before a trade registry official, displaying the signatures to be used under the corporate title by the appointed company managers.
  • Chamber of Commerce Registration Form: The official declaration form containing the personal and professional details of the partners and managers, delivered during the initial registration.
  • Capital Term Commitment: A formal document containing an explicit undertaking that the remaining cash capital will be fully paid within 24 months following the company’s registration. (According to the 2026 legal framework, the minimum capital for a limited liability company is 50.000 TL; there is no capital blockage obligation at the time of establishment).
  • Lease Agreement or Title Deed Copy: A current lease contract signed with the property owner, proving the official, legal headquarters address of the entity.

Required Documents for Sole Proprietorship Formation in Turkey

Generally preferred by small to medium-sized businesses, freelancers, and independent consultants, establishing a sole proprietorship is the fastest bureaucratic method for setting up a business in Turkey. Today, this process can be initiated digitally through the e-Devlet (e-Government) portal infrastructure alongside physical applications. The list of required elements includes:

  • Signature Circular / Signature Declaration: The official signature specimen sheet executed by the business owner before a notary public or trade registry office.
  • Certificate of Residence: A current residential address document obtained from civil registry offices or via the e-Devlet portal.
  • Copy of National ID Card: A clear, double-sided copy of the applicant’s identification card displaying all identity details openly.
  • Tax Office Application Details: The formal “commencement of operations” notification form submitted to the relevant tax office, along with documents indicating the business’s activity code (NACE code).
  • Proof of Workplace Address: A copy of the lease agreement for the area declared as the business headquarters or the title deed if the property belongs to the entrepreneur.

Required Documents for Foreigners Registering a Company in Turkey

Turkish legislation actively encourages foreign direct investment, ensuring international investors hold identical rights to domestic entrepreneurs. To successfully navigate company registration in Turkey as a foreign real person or legal entity, the following specialized documents must be prepared:

  • Notarized Passport Translation: Certified copies of the foreign partners’ or managers’ passports, translated into Turkish by a sworn translator and legalized by a notary public.
  • Potential Tax Identification Number: The official tax number obtained from the tax offices of the Gelir İdaresi Başkanlığı (Revenue Administration) to carry out financial transactions within Turkey.
  • Apostilled Certificate of Activity: If a partner is a foreign legal entity, the current certificate of activity obtained from the trade registry of their home country, bearing an Apostille stamp and accompanied by a notarized Turkish translation.
  • Power of Attorney: A specialized power of attorney issued by consulates or notary publics, allowing a Turkish law firm or legal representative to manage the corporate setup steps on behalf of the investor.
  • Photographs of the Foreign Official: Two biometric passport-sized photographs taken within the last 6 months.

Company Formation Costs and Taxes

The official fees, chamber registration dues, and consultancy expenses to be paid during the process vary depending on the chosen corporate structure. The total cost of establishing a business in Turkey depends heavily on the capital structure and the number of partners. Based on 2026 fiscal data, the baseline expenses are structured as follows:
