The Social Security Institution, commonly known as SGK in Turkey, plays a central role in the Turkish employment system. It regulates social insurance, retirement, health coverage, workplace accident compensation, disability benefits, and maternity rights for millions of workers. For employers—local or foreign—understanding SGK obligations is essential to operating legally and managing payroll correctly. For employees and expatriates living in Turkey, SGK membership is the gateway to accessing public healthcare and securing long-term social benefits.
This comprehensive guide explains what SGK in Turkey is, how it works, how contributions are calculated, and why it is critical for businesses hiring employees in Turkey.
1. Definition: What Is SGK in Turkey?
SGK in Turkey refers to the Sosyal Güvenlik Kurumu, or Social Security Institution, which is the government body responsible for:
- Public health insurance
- Retirement pensions
- Disability insurance
- Maternity and parental benefits
- Workplace injury compensation
- Unemployment protection (in collaboration with İŞKUR)
SGK ensures that all workers—Turkish citizens, foreign residents with work permits, and certain self-employed individuals—receive social security protections throughout their working lives.
2. The Role of SGK in the Turkish Employment System
SGK is one of the most important institutions in Turkish labor legislation. Its primary responsibilities include:
✔ Registering companies and employees
Every employer must register with SGK before hiring an employee.
✔ Collecting social security contributions
These contributions fund pensions, health, and insurance programs.
✔ Managing universal health insurance
Employees covered by SGK receive access to public healthcare services.
✔ Tracking employee work history
SGK records determine retirement eligibility and benefit calculations.
✔ Paying pensions and insurance compensations
These include retirement, disability, survivor, and injury payments.
✔ Regulating employer compliance
SGK conducts audits and applies penalties for violations.
For companies operating in Turkey, compliance with SGK requirements is not optional—it is a legal obligation.
3. Who Must Be Registered with SGK in Turkey?
The following groups must be registered:
1. Employees Working Under an Employment Contract
All full-time and part-time workers must be registered by the employer.
2. Foreign Employees with a Work Permit
Foreign workers contribute to SGK in the same way as Turkish citizens.
3. Self-Employed Individuals (Bağ-Kur)
Entrepreneurs, freelancers, and business owners must register under a separate category.
4. Public Sector Employees (Emekli Sandığı)
Managed through an integrated SGK system but under special rules.
SGK in Turkey ensures social protection for all working individuals, regardless of nationality or sector.
4. SGK Registration Requirements for Employers
Before hiring an employee, employers must:
✔ Register the company with SGK
This includes obtaining a workplace registration number.
✔ Register each employee before they start working
Registration must be completed at latest one day before employment begins.
✔ Maintain monthly payroll records
Employers must calculate contributions, submit declarations, and pay SGK premiums on time.
Failure to comply can result in heavy penalties, making professional payroll management essential.
5. Contribution Rates: How SGK in Turkey Is Calculated (2025)
SGK contributions are shared between employees and employers. The employer pays the majority, while employees contribute a smaller portion deducted from their salary.
Below is the standard breakdown:
1. Social Security Contributions
| Type of Contribution | Employer | Employee | Total |
|---|---|---|---|
| Long-Term Insurance (pension, disability) | 11% | 9% | 20% |
| Short-Term Insurance (work accident, illness) | 2% | – | 2% |
| General Health Insurance | 7.5% | 5% | 12.5% |
| Unemployment Insurance | 2% | 1% | 3% |
| Total SGK Rate | 22.5% | 15% | 37.5% |
Employers also benefit from various government incentives that can reduce SGK premiums significantly.
6. What Benefits Does SGK in Turkey Provide?
SGK contributions guarantee access to several major benefits:
1. Retirement Pension (Emeklilik)
Employees earn pension rights based on:
- Number of premium days
- Retirement age
- Years of service
2. Universal Health Insurance
SGK offers free or low-cost treatment through state hospitals, clinics, and contracted private hospitals.
3. Work Accident and Occupational Illness Insurance
Covers:
- Medical treatment
- Temporary disability payments
- Permanent disability compensation
- Survivor payments to family
4. Maternity and Parental Benefits
SGK supports employees with:
- Maternity leave compensation
- Breastfeeding allowance
- Paternity leave rights
- Temporary disability payments
5. Disability Benefits
Workers unable to continue employment for medical reasons may qualify for early retirement or long-term disability payments.
6. Survivor Benefits
Families of deceased insured workers may receive monthly support.
7. Unemployment Insurance
Employees who lose their job involuntarily receive monthly payments depending on their work history.
SGK in Turkey ensures a comprehensive social protection system for employees and their families.
7. SGK Procedures Employers Must Follow
Employers must comply with several ongoing obligations:
1. Monthly Premium and Service Declaration
Submitted via the online SGK system (E-Bildirge).
2. Payment of Premiums
Must be paid by the end of each month to avoid penalties.
3. Notification of New Hires and Terminations
All hires must be declared before they start working; terminations must be declared within 10 days.
4. Workplace Code Assignments
SGK classifies businesses by risk category, affecting short-term insurance rates.
5. Keeping Records
Documents such as employment contracts, payroll records, and attendance logs must be systematically maintained and available for inspection.
6. Compliance with Inspections
SGK regularly conducts audits to ensure legal compliance.
8. SGK and Foreign Employees in Turkey
Foreign workers with valid work permits must be registered under SGK just like Turkish citizens.
Key points:
✔ SGK coverage is mandatory once the employee starts work
✔ Foreign workers have access to public health services
✔ SGK contributes toward retirement (although international agreements may apply)
✔ Foreign employees cannot opt out of SGK unless exempted under bilateral treaties
SGK in Turkey ensures equal social protections for foreign talent.
9. Penalties for Non-Compliance with SGK Regulations
SGK imposes strict penalties for failing to follow regulations:
❗ Failure to register employees
Fines can reach thousands of liras per employee.
❗ Late payment of contributions
Interest charges and additional penalties apply.
❗ Incorrect or false declarations
SGK conducts audits and imposes sanctions for irregularities.
❗ Hidden employment (“off-the-record workers”)
Considered a serious violation with very high penalties.
❗ Blocking access to government incentives
Non-compliant companies lose eligibility for SGK premium discounts.
Compliance with SGK in Turkey is therefore essential for legal and financial protection.
10. SGK for Self-Employed Individuals (Bağ-Kur)
Independent business owners, freelancers, shopkeepers, and partners in LLCs are classified under Bağ-Kur.
They must:
- Register themselves
- Pay SGK premiums monthly
- Maintain health insurance coverage
- Earn retirement rights through Bağ-Kur
Bağ-Kur obligations differ from employee SGK contributions but provide similar protections.
11. Digital Transformation of SGK in Turkey
SGK has undergone major modernization over the past decade:
✔ Online premium declarations
✔ E-Devlet integration
✔ Digital medical prescriptions
✔ Electronic service tracking
✔ Automated employer reporting systems
✔ Direct communication channels
These improvements have made the social security system faster, more transparent, and more accessible.
