When forming a company in Turkey, one of the most important decisions is choosing the right legal structure. This guide compares the sole proprietorship (real-person business), Limited Şirket (Ltd. Şti.; limited liability company/LLC) and Anonim Şirket (A.Ş.; joint stock company/JSC) under the 2026 capital, tax, liability and social security rules.
Each company type has its own advantages and disadvantages. There are significant differences in capital requirements, liability structure, establishment processes and tax obligations.
In this article, we will examine the three main company types in detail, provide a comparative analysis and evaluate which company type is more suitable in which situation.
Terminology note: “Sole proprietorship” here means the everyday single real-person business. In the Turkish Commercial Code, şahıs şirketleri are collective and limited partnerships. Ltd. Şti. and A.Ş. are Turkish-law entities; LLC, GmbH, SARL or similar labels are only explanatory equivalents, not identical legal forms.
What are the main company types in Turkey?
This guide focuses on the three structures compared most often in practice: the sole proprietorship, Limited Şirket (Ltd. Şti.) and Anonim Şirket (A.Ş.). The Turkish Commercial Code also provides for collective companies, limited partnerships and cooperatives.
What is the main difference between Ltd. Şti. and A.Ş.?
Ltd. Şti. is often chosen by SMEs that want a simpler management structure. A.Ş. is more flexible for share transfers, investor structures and access to capital markets. Capital, public-debt liability and governance rules differ.

🔴CRITICAL WARNINGS (2026)
1. Mandatory Capital Increase – Deadline: 31.12.2026
⏰ URGENT: Must be completed within this year!
- Limited Company: Those with capital below 50,000 TL
- Corporation: Those with capital below 250,000 TL
⛔ If not increased on time, the company legally dissolves (automatically terminates).
📌 The Ministry of Trade has the authority to extend the period twice, by one year each time, but this should not be relied upon. Completing within 2026 is the safest!
2. Liability for debts in limited and joint-stock companies
Private-law debts and public receivables are assessed separately.
- The company’s private-law debts are borne by the company’s assets.
- Partners remain liable for the capital they subscribed.
- Limited-company partners are directly liable, in proportion to their capital shares, for public receivables that cannot be collected in full or in part from the company, or that appear uncollectible, under Article 35 of Law No. 6183.
- Managers’/legal representatives’ liability is assessed separately under Tax Procedure Law Art. 10 and repeated Art. 35 of Law No. 6183.
An A.Ş. shareholder is not, merely as a shareholder, liable beyond subscribed capital. Public-debt liability may still arise from being a board member or legal representative.
Legal basis: Law No. 6183 Arts. 35 and repeated 35; Tax Procedure Law Art. 10.
