Turkish International Ship Registry (TISR) Guide 2026: Key Advantages and Current Regulations

The Turkish International Ship Registry (TISR), locally known as TUGS, offers significant fiscal and administrative advantages designed to enhance the competitiveness of the Turkish merchant fleet and encourage shipowners to fly the Turkish flag. As of 2026, the TISR framework has been further modernized with a focus on decarbonization (green transformation) and digitalization.

What is TISR? Why Choose the Turkish Flag?

TISR is an “Open Registry” (or Second Registry) established under Law No. 4490. It was created to allow the Turkish fleet to compete on equal footing with “flags of convenience” in international waters. By providing substantial tax incentives and reducing operational costs, TISR prevents the flight of local capital to foreign jurisdictions while strengthening Turkey’s maritime presence.

Crewing and Seafarer Employment Regulations

Employment on TISR-registered vessels is subject to specific statutory requirements. According to the 2026 updated regulations:

• Nationality of the Master: Regardless of the shipowner’s nationality, the Master (Captain) of any vessel or yacht registered in TISR must be a Turkish citizen.
• The 51% Crew Rule: If the shipowner is a Turkish citizen or a legal entity established in Turkey, at least 51% of the crew (excluding the Master) must be Turkish citizens.
• Flexibility for Foreign Shipowners: If the shipowner is a foreign national or entity, there is no specific nationality quota for the crew, though the requirement for a Turkish Master remains mandatory.

Tax Exemptions and Financial Incentives

TISR acts as a highly favorable fiscal regime for maritime operations. Key exemptions include:

1. Financial Transaction Tax (BSMV) Relief: Banking and insurance transactions related to these vessels enjoy significant tax reliefs.
2. Corporate and Income Tax Immunity: Earnings derived from the operation and transfer of TISR-registered vessels are exempt from Corporate and Income Tax.
3. Stamp Duty and Fee Exemptions: Transactions involving the purchase, sale, mortgage, and registration of vessels are exempt from stamp duties and various administrative fees.

Green Shipping Incentives

In line with global sustainability goals, the TISR legislation now includes specific incentives for “Green Vessels”:

• Modernization Support: New-build vessels meeting high energy efficiency standards benefit from expedited registration processes.
• Zero-Emission Vessel Discounts: Ships powered by non-fossil fuels (e.g., electric, hydrogen) are exempt from initial registration fees and receive a 50% discount on annual tonnage taxes.

Digitalization: The Seafarers Information System (GİBS)

All crewing procedures and registry records are now managed via the GİBS (Gemi Adamları Bilgi Sistemi) digital platform. This transition has eliminated bureaucratic bottlenecks, allowing for real-time tracking of payroll, certification, and flag-state compliance.
