The Social Security Institution (SGK – Sosyal Güvenlik Kurumu) is one of the most important pillars of Turkey’s employment and welfare system. It regulates social insurance, healthcare coverage, and pension rights for millions of employees, employers, and self-employed individuals across the country.
For companies operating in Turkey—and especially for foreign employers—understanding SGK is essential for legal compliance, payroll accuracy, and employee protection.
1. What Is SGK?
SGK is Turkey’s unified social security authority, established to manage all social insurance branches under one institution. It oversees:
- Health insurance
- Retirement and pension schemes
- Work accident and occupational disease coverage
- Maternity, disability, and survivor benefits
SGK operates under the Ministry of Labor and Social Security and applies to both Turkish citizens and legally employed foreign workers.
2. Who Must Register with SGK?
SGK registration is mandatory for nearly all working individuals in Turkey, including:
- Employees working under an employment contract
- Employers hiring staff in Turkey
- Self-employed individuals and company owners
- Foreign employees with valid work permits
Employers are legally required to register employees with SGK before the first day of work. Failure to do so can result in heavy administrative fines and retroactive contribution assessments.
3. SGK Contribution Structure
SGK contributions are calculated as a percentage of the employee’s gross salary and are shared between the employer and the employee.
Contribution Breakdown (General Overview)
- Employer contribution: Covers social insurance, health insurance, unemployment insurance, and other statutory charges
- Employee contribution: Deducted directly from the gross salary
The total SGK contribution rate is substantial, making payroll planning and compliance critical for employers.
💡 Contribution rates may vary depending on incentives, sector, and government-supported employment programs.
4. Types of SGK Insurance Coverage
SGK provides comprehensive social protection through multiple insurance branches:
Health Insurance (GSS)
SGK grants access to Turkey’s public healthcare system, including:
- Public hospitals
- State-affiliated private hospitals
- Prescription medication coverage
Registered employees and their dependents benefit from healthcare services once contributions are paid.
Pension and Retirement Insurance
SGK manages retirement pensions based on:
- Contribution period (number of premium days)
- Age requirements
- Salary history
Both employees and employers contribute toward long-term pension rights.
Work Accidents and Occupational Diseases
Employers must insure employees against workplace accidents and occupational illnesses. SGK covers:
- Medical treatment
- Temporary incapacity payments
- Permanent disability compensation
This coverage applies from the first day of registered employment.
Unemployment Insurance
Employees who lose their job under qualifying conditions may receive unemployment benefits funded through SGK-linked unemployment insurance contributions.
5. SGK Obligations for Employers
Employers in Turkey have strict SGK-related responsibilities, including:
- Employee registration and termination notifications
- Monthly premium and service declarations
- Timely payment of SGK contributions
- Maintaining accurate payroll and personnel records
Delays or errors can trigger penalties, interest charges, and inspections.
6. SGK for Foreign Employees
Foreign nationals working in Turkey must also be registered with SGK unless covered by a bilateral social security agreement. Key points include:
- SGK registration is tied to a valid work permit
- Some foreign employees may be exempt for a limited period if insured abroad
- Employers remain responsible for SGK compliance
This makes SGK registration a critical step in employing expatriates in Turkey.
7. SGK Incentives and Employment Support
To encourage employment and formalization, the Turkish government offers various SGK incentives, such as:
- Reduced employer contribution rates
- Youth and female employment incentives
- Incentives for strategic industries and regions
These incentives can significantly reduce labor costs when applied correctly.
8. SGK Audits and Inspections
SGK regularly conducts audits to ensure compliance. Inspections may focus on:
- Undeclared employees
- Incorrect salary declarations
- Missing contribution payments
- Misuse of incentives
Professional payroll and HR management is essential to avoid audit risks.
9. Why SGK Matters for Businesses
SGK is not just a legal obligation—it directly affects:
- Employee welfare and job security
- Employer reputation and risk exposure
- Total employment costs
- Access to public healthcare and pensions
Companies that manage SGK processes correctly build trust with employees and avoid costly legal disputes.
SGK is the backbone of Turkey’s social security and employment system. From healthcare access to retirement pensions and workplace protection, it plays a vital role in both employee well-being and employer compliance.
For companies operating in Turkey—especially foreign investors and growing businesses—understanding SGK rules, contribution structures, and obligations is essential for sustainable and compliant operations.
