Doing Business in Turkey 2026: Commercial Law Guide for Investors

Turkey remains a strategic hub connecting Europe, Asia, and the Middle East. For international investors, the Turkish legal landscape offers significant opportunities—specifically the ability for foreigners to own 100% of a company without a local partner.

However, the “Turkish Commercial Code” (TTK) has strict rules regarding capital structure, board responsibilities, and tax compliance. In 2026, minimum capital requirements have increased significantly to combat inflation.

This guide provides a comprehensive “Gold Standard” roadmap for establishing and managing a business in Turkey.

1. Choosing the Right Entity: LTD vs. A.Ş.

The two most common corporate structures are the Limited Liability Company (LTD) and the Joint Stock Company (A.Ş.). Choosing the wrong one can have serious consequences for your personal liability.

A. Limited Liability Company (LTD / Ltd. Şti.)

• Best For: Small to Medium Enterprises (SMEs), trading companies, local shops.
• Minimum Capital (2026): 250,000 TL.
• Number of Shareholders: Min 1, Max 50.
• Share Transfer: Difficult. Requires Notary approval and Trade Registry approval.

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

• Best For: Large investments, investors seeking anonymity, startups planning to take investment.
• Minimum Capital (2026): 500,000 TL (for non-public).
• Share Transfer: Easy. Can be done via simple written agreement or share certificate transfer. No Notary required.

2. 2026 Minimum Capital Increases

Effective from January 1, 2026, the Ministry of Trade has updated the threshold values due to inflation.

Company Type	Old Capital (Pre-2024)	2026 Required Capital
Limited (LTD)	10,000 TL	250,000 TL
Joint Stock (A.Ş.)	50,000 TL	500,000 TL

Note for Existing Companies: If you established your company years ago with 10k or 50k capital, you are legally required to perform a “Capital Increase” (Sermaye Artırımı) to meet the new minimums. Failure to do so may lead to the “Dissolution” of your company by the court (TTK liquidation rules).

3. Taxation of Companies in 2026

Turkey’s tax system is modern but rigorous. As a foreign investor, understanding your tax burden is crucial for ROI.

A. Corporate Income Tax (Kurumlar Vergisi)

• Standard Rate: 25% (Increased in recent years).
• Financial Sector (Banks, etc.): 30%.
• Exporters: Manufacturing and exporting companies enjoy a 5% discount, effectively paying 20%.

B. Withholding Tax (Stopaj)

• Dividend Distribution: If you distribute profits to shareholders, you pay a 10% withholding tax.
• Rent Payments: If the company rents an office, it withholds 20% of the rent and pays it to the tax office on behalf of the landlord.

C. VAT (KDV)

• Standard Rate: 20% (General goods and services).
• Reduced Rates: 10% (Textiles, basic food, medical services) and 1% (Basic agricultural products).

4. The “Prudent Merchant” Rule (Basiretli Tacir)

Turkish Law treats merchants differently from regular consumers. Under TTK Art. 18/2, every merchant is expected to act as a “Prudent Businessman”.

What does this mean?

1. Strict Contracts: You cannot claim “I didn’t read the fine print” or “I didn’t know the interest rate was high.” The judge assumes you knew.
2. 8-Day Objection Rule: If you receive an invoice and do not object via Notary/Registered Mail within 8 days, you are deemed to have ACCEPTED the content and price of that invoice.
3. Interest Rates: Commercial default interest rates are much higher than consumer rates.

5. Key Steps to Company Formation

1. MERSIS Registration: Everything starts with the Central Registry System (MERSIS).
2. Articles of Association: Must be drafted in Turkish. For foreigners, a passport translation is required.
3. Capital Blockage: For A.Ş., 25% of the capital must be blocked in a Turkish Bank account before registration. For LTD, this is not required upfront (can be paid in 24 months).
4. Trade Registry: Signing documents at the Trade Registry Office.
5. Tax Office & Signature Circular: Obtaining the “Vergi Levhası” and the “Imza Sirküleri” (power of attorney for the director).
6. E-Signature & KEP: Mandatory for all companies in 2026.

6. Mergers & Acquisitions (M&A) Basics

If you plan to buy an existing Turkish company instead of starting from scratch (Brownfield Investment), beware of Successor Liability.

7. Top 5 Mistakes Foreign Investors Make

Mistake 1: Choosing LTD Instead of A.Ş. for Tax Protection

Foreign investors often choose LTD because the setup is slightly cheaper. They don’t realize that in LTD, their personal assets (bank accounts, car) can be seized by the Turkish Tax Office if the company has unpaid tax debts. Recommendation: If you have high volume, go for A.Ş.

Mistake 2: Using a “Nominee” Director without Protection

To avoid travel, investors appoint a Turkish friend as Director. If that Director signs bad checks or loans, the company is liable. Always use a professional “Limited Authority” structure (Internal Directive).

Mistake 3: Forgetting the “Electronic Notification” Address (UETS)

Turkish courts and tax offices send notifications electronically to your UETS address. If you don’t check it, you miss deadlines (e.g., 7 days to object to a Payment Order) and lose cases automatically.

Mistake 4: Not adjusting for Hyperinflation

Your contracts usually state prices in TL. With inflation, a fixed TL price can bankrupt you in 6 months. Solution: Use ” FX-indexed” clauses (if legal between two Turkish entities) or strict price adaptation clauses legally drafted.

Mistake 5: 15-Day Limit for Lost Books

If your office burns down or floods and you lose your commercial books, you must sue for a “Loss Certificate” (Zayi Belgesi) within 15 days. If you miss this, you cannot prove anything to the Tax Inspector and will face massive fines for “hiding books”.
