Your legal team in Frankfurt just flagged it: the executive hired in Istanbul six months ago via a global EOR platform is on the wrong contract type. Fixed-term, with no objective justification. Under Turkish Labor Law Article 4857, that contract converts to indefinite automatically, with full severance liability and no waiver. The EOR’s support ticket is on day four with no resolution in sight.
This scenario plays out more often than global EOR vendors admit. Turkey’s employment framework is comprehensive, employee-protective, and specific in ways that generic SaaS platforms miss. Datassist has managed payroll and employment compliance in Turkey since 1999. Below is the 2026 employment law framework every foreign employer should have before putting a single employee on Turkish payroll, whether through an entity, an EOR, or a payroll outsourcing arrangement.

What Turkish Employment Law Covers
Turkish employment law is primarily governed by Labor Law No. 4857, which came into force in 2003 and replaced the older Labor Law No. 1475. Law No. 4857 covers most private-sector employment relationships in Turkey. Senior managers and specific professionals not covered by 4857 may fall under the Turkish Code of Obligations instead.
Unless you have specific legal advice otherwise, assume Law No. 4857 applies and build your employment framework around its minimum protections.
The domains it covers include:
- Employment contracts (types, mandatory clauses, language)
- Working hours and overtime
- Annual leave, public holidays, and sick leave
- Termination procedures, notice periods, and job security
- Severance pay calculation and eligibility
- Social security contributions (SGK)
- Data privacy in employment (KVKK)
- Work permits for foreign nationals
Turkish employment law is employee-protective by design. Parties cannot contract out of statutory minimums. If your contract offers less than the statutory minimum (on notice periods, annual leave, or overtime rates), the statutory minimum applies automatically. A waiver signed by the employee does not change this.
Regulation Note: Law No. 4857 covers most employment relationships in Turkey. The Turkish Code of Obligations applies to top-level managers (general directors and similar) who are not considered “employees” under 4857. If you’re unsure which statute applies, assume 4857 applies and plan for its minimum protections.
What Changed in 2026: Law No. 7566 and New SGK Rates
Law No. 7566, effective 1 January 2026, changed three things at once: the SGK earnings ceiling, the Invalidity, Old Age, and Death premium, and the Treasury incentive rate for non-manufacturing employers.
The New SGK Earnings Ceiling
The social security earnings ceiling rose from 7.5 times the minimum wage to 9 times the minimum wage. At the 2026 minimum wage of TRY 33,030 gross per month, this puts the new ceiling at TRY 297,270 per month.
Earnings above this ceiling are exempt from SGK contributions. For employers paying high-compensation employees (expat executives, senior technical specialists, or senior managers on local-plus packages), the ceiling change increases total SGK exposure compared to 2025 calculations. Any payroll model built on the old 7.5× ceiling is now understating employer liability.
The Invalidity, Old Age, and Death Premium Increase
The Invalidity, Old Age, and Death premium rate increased from 20% to 21% under Law No. 7566. The employer’s share specifically increased from 11% to 12%. This is a direct cost increase for all Turkish employers, regardless of sector or headcount.
Incentive Changes for Non-Manufacturing Employers
The 4-point Treasury incentive for non-manufacturing employers was reduced to a 2-point incentive. Manufacturing employers retain the 5-point incentive. After Law No. 7566 adjustments, the employer SGK cost picture looks like this:
| Scenario | Effective Employer SGK Rate |
|---|---|
| Full rate (no incentive applied) | 22.75% |
| Non-manufacturing (2-pt incentive) | 20.75% |
| Manufacturing (5-pt incentive) | 17.75% |
| With additional SGK incentive optimization | 18.75%–21.75% depending on sector and eligible headcount |
Regulation Note: Law No. 7566 took effect on 1 January 2026. If your Turkish payroll has not been recalibrated for the 9× earnings ceiling and the updated Invalidity, Old Age, and Death premium rate, your 2026 SGK filings are likely understating contributions. Datassist’s payroll team flagged and corrected this for 500+ active clients before the first January cycle closed.
Employment Contracts in Turkey
Contract Types and the Fixed-Term Trap
Turkish law recognizes several contract types: indefinite-term, fixed-term, part-time, on-call, and remote working agreements. The default, and the form that Turkish courts prefer, is the indefinite-term contract.
Fixed-term contracts are only valid when there is objective justification for the time limitation: seasonal work, a specific project with a defined end date, or replacement of an employee on leave. If a fixed-term contract lacks objective justification, it converts automatically to an indefinite-term contract under Article 11 of Law No. 4857. The employee then carries all the protections of an indefinite-term employee, including full severance entitlement.
Risk: One of the most common compliance failures by foreign employers using global EOR platforms is accepting a generic fixed-term contract for an ongoing role. The role is permanent, the project is continuous, but the contract says “12 months.” Turkish courts do not accept this. The contract converts to indefinite, and all subsequent termination must follow indefinite-term rules.
Mandatory Contract Clauses
Every Turkish employment contract must specify:
- Identity of the employer and employee
- Job title and description
- Place of work
- Start date
- Gross salary and payment frequency
- Daily/weekly working hours
- Annual leave entitlement
- Termination terms
For contracts with Turkish national employees, the agreement must be in Turkish, or dual-language with Turkish taking precedence in any dispute.
The statutory probation maximum is 2 months. A collective bargaining agreement can extend it to 4 months, but never beyond that. During probation, either party may terminate without notice or severance (with the exception of any contractual notice clause you have agreed to).
Working Hours, Overtime, and Annual Leave
Working Hours and Overtime
The standard workweek under turkish labor law is 45 hours per week, spread across no more than 11 hours per day. Both caps are hard limits.
Overtime kicks in for any work beyond 45 hours per week, or below that threshold if a lower working time was agreed contractually. Overtime compensation rates:
- Standard overtime: 150% of the employee’s hourly wage (or 1.5 hours time off in lieu per overtime hour, with employee consent)
- Work on weekly rest day or public holidays: 200% of the hourly wage
- Annual overtime cap: 270 hours per year
The 270-hour cap is often overlooked. If your employee works significant overtime through the year, you need to track cumulative hours and stop at the statutory ceiling, or obtain a specific agreement with the trade union for extended overtime.
Annual Leave Entitlements
Annual leave in Turkey accrues based on length of service. The minimums under Law No. 4857 are:
| Service Length | Minimum Annual Leave |
|---|---|
| 1–5 years | 14 working days |
| 5–15 years | 20 working days |
| 15+ years | 26 working days |
Annual leave entitlement begins after the first full year of service. Employees working in hazardous or underground roles receive a minimum of 20 days from the start. Leave cannot be converted to cash while employment continues. It can only be paid out on termination.
Turkey also has 15.5 public holidays per year, including national holidays and religious festivals (Eid ul-Fitr, Eid ul-Adha). These are mandatory paid days off.
Remote Working in Turkey
Remote and hybrid working is regulated under Law No. 4857 and the Regulation on Remote Working (published in the Official Gazette, No. 39363). If your Turkish employees work from home, a written remote working agreement is required. Employers must cover or reimburse equipment and internet costs. KVKK obligations apply to home-office data environments, which creates additional compliance obligations for cross-border data flows.
Termination, Notice Periods, and Severance Pay
Turkey does not have at-will termination.
Notice Periods
Statutory minimum notice periods under Law No. 4857 scale with service length:
| Service Length | Minimum Notice Period |
|---|---|
| Less than 6 months | 2 weeks |
| 6 months to 1.5 years | 4 weeks |
| 1.5 years to 3 years | 6 weeks |
| More than 3 years | 8 weeks |
These are minimums. Your contract can specify a longer notice period, but cannot reduce below the statutory floor. The employer can place the employee on paid garden leave for the notice period (working the employee out of the office while keeping them on payroll).
Severance Pay
Severance pay is payable when employment ends in the following circumstances: employer-initiated termination (without just cause), employee resignation due to employer misconduct, military service call-up, retirement, or death.
The calculation: 30 days’ gross salary per full year of service, plus a proportional amount for any partial year. The ceiling per year of service is indexed by the government. The H1 2026 ceiling is TRY 64,948.77 per year of service. (This ceiling applies per year, not to the total payout.)
An employee must have at least 1 full year of service to qualify for severance.
Expert Take: Foreign employers consistently underestimate severance liability in Turkey. A senior employee with 8 years of service on a TRY 250,000 monthly gross salary generates approximately TRY 520,000 in total severance exposure — the H1 2026 ceiling of TRY 64,948.77 per year of service caps the calculation. That obligation accrues from day one of employment and should be modeled in your headcount cost budgets. Datassist’s EOR clients receive monthly liability accrual reporting so finance teams are never surprised at termination.
Invalid Termination and Job Security
Employees at workplaces with 30 or more employees, who have at least 30 days of service, are protected under job security rules (iş güvencesi). If the employer terminates without valid written grounds, the employee can challenge the termination in court and claim either:
- Reinstatement to their previous position, or
- Compensation equivalent to 4 to 8 months’ salary
Documentation is not optional here. Performance issues, disciplinary actions, and written warnings must be on file before any termination.
Mandatory Mediation Before Labor Court
Since January 2018, Turkey requires mandatory mediation (arabuluculuk) before any labor court lawsuit. If an employee wants to sue for wrongful termination, the case must go to a registered mediator first. If mediation fails, the case proceeds to court. The mediation session must be scheduled within 3 weeks of application. It typically runs for 1 to 3 sessions.
For foreign employers, this adds a required pre-litigation step that doesn’t exist in most EU or US legal systems. Build it into your response timeline when a termination dispute arises.
SGK Social Security Obligations for Employers
SGK (Sosyal Güvenlik Kurumu), the Social Security Institution, is the Turkish government body that collects and administers social security contributions. Every employee working in Turkey must be registered with SGK, and every employer must file monthly declarations.
SGK registration must happen before the employee’s first day of work, not on the first day. Late registration triggers penalties equal to twice the missed premium, plus statutory interest.
Monthly SGK Declarations
Employers submit monthly e-Bildirge declarations through SGK’s online system. Each declaration reports insurable earnings, premium types, and employee headcount. Declarations are due by the 23rd of the following month for most employers. Late or incorrect filings carry penalties.
2026 Employer SGK Rates
After Law No. 7566 adjustments, the 2026 employer SGK contributions break down as:
| Contribution Type | Employer Rate |
|---|---|
| Long-term insurance (invalidity, old age, and death) | 12% (increased from 11% in 2025) |
| Short-term insurance (work accident, occupational disease) | 1.25% (standard base rate; varies up to 2%+ by hazard class) |
| General health insurance (GSS) | 7.5% |
| Unemployment insurance | 2% |
| Total standard employer rate | 22.75% (before incentives) |
Treasury support: TRY 1,270 per month per eligible employee (deducted directly from the monthly SGK payment owed).
SGK Incentive Optimization
Most foreign employers operating through generic EOR or payroll outsourcing arrangements never access Turkey’s SGK incentive programs. These programs (funded by the Treasury and administered through SGK) can reduce the effective employer rate from 22.75% to 18.75%–21.75%, depending on sector, employee profile, and eligibility criteria.
For a company with 50 employees in Turkey, the difference between an unoptimized 22.75% and an optimized 19.75% rate can exceed TRY 1.5 million per year. This is not a niche opportunity. It applies to most employers meeting standard eligibility conditions.
Data Point: Datassist has managed SGK incentive applications for over 500 active clients in Turkey. The average client accessing the standard non-manufacturing incentive reduces their effective employer SGK rate by approximately 2 to 5 percentage points of gross payroll. Most of these clients were not accessing incentives at all before working with a specialized payroll provider.
KVKK: Turkey’s Data Protection Law and Your Employer Obligations
KVKK (Kişisel Verilerin Korunması Kanunu) is Turkey’s data protection law, enacted in 2016 and broadly aligned with the European Union’s GDPR framework. For employers in Turkey, KVKK creates specific obligations around employee data processing.
Most routine employee data processing (payroll, SGK filing, contract management) is lawful under the “necessary for the performance of an employment contract” basis. You do not need explicit consent for data that is strictly necessary to manage the employment relationship. You do need it for sensitive data, including health records, biometrics, and disability status.
Cross-border data transfers are where most foreign employers run into trouble. If your Turkish employee data sits on servers outside Turkey (EU-based HRIS platforms, US cloud tools), you either need to rely on a country with an “adequate” framework under KVKK (Turkey’s approved-country list differs from the EU’s) or use standard contractual clauses approved under KVKK. The rules on cross-border transfer became stricter in 2024. Many foreign employers running Turkish employees through global HRIS platforms are not in full compliance.
Employers with more than 50 employees must also register with VERBİS, Turkey’s data controller registry. Failure to register carries administrative fines.
Regulation Note: Datassist’s payroll platform is ISO 27001 certified and ISAE 3402 assured. Turkish employee data is stored in-country by default, which removes the cross-border transfer compliance requirement for employers using Datassist’s managed services. Data security and information security compliance are built into the service, not add-ons.
Work Permits for Foreign Nationals Working in Turkey
Foreign nationals who are not citizens of Turkey require a valid work permit to work legally in the country. The permit must be in place before the employee starts work. There are no grace periods.
The Application Process
Employers apply through the e-İzin system, the Ministry of Labour and Social Security’s online permit portal. The application must be initiated by the employer, not the employee. Required documents include: employer’s tax registration, SGK records, the employment contract, and the employee’s academic credentials (for permit categories that require them).
Standard processing time: approximately 30 working days from a complete application.
The 5:1 Ratio Rule
For every foreign employee at a Turkish workplace, the employer must have at least 5 Turkish national employees on SGK. This ratio is calculated at the company level. For companies with fewer than 5 Turkish employees, the minimum is 1 Turkish employee per foreign employee.
Exceptions exist for certain sectors, roles, and company types, including companies established with significant foreign capital or those operating in specific technology or R&D roles.
Minimum Salary Thresholds (2026)
Work permits require minimum gross salary thresholds depending on the role category:
| Role Category | Minimum Monthly Gross Salary (2026) |
|---|---|
| Specialist, teacher, skilled worker | TRY 66,060 (2× min. wage) |
| Department manager, team lead | TRY 99,090 (3× min. wage) |
| Engineer, architect | TRY 132,120 (4× min. wage) |
| Senior manager, general director, C-suite, pilot | TRY 165,150 (5× min. wage) |
These thresholds are set at multiples of the minimum wage and change whenever the minimum wage is updated. The current thresholds are effective from January 2026.
Permit validity: initial permits are issued for up to 1 year. After 1 year of continuous employment, permits are renewable for up to 3 years. After 8 years of continuous legal employment, a permanent work permit may be available.
For specialist support with the e-İzin process, eligibility assessment, and ongoing renewals, Datassist’s work permit consulting team manages the full application cycle.
Frequently Asked Questions
What is the main employment law in Turkey?
Turkish employment relationships are primarily governed by Labor Law No. 4857, which came into force in 2003. It covers employment contracts, working hours, overtime, annual leave, termination, and severance for most private-sector workers. Senior executives and certain professionals may instead be governed by the Turkish Code of Obligations.
What are the working hours in Turkey?
The standard maximum workweek in Turkey is 45 hours per week, with a daily maximum of 11 hours. Overtime applies to any work beyond 45 hours per week and is compensated at 150% of the employee’s hourly wage (or time off in lieu at 1.5 hours per overtime hour). The annual overtime cap is 270 hours.
How does severance pay work in Turkey?
Severance pay equals 30 days of gross salary for each full year of service. It is payable on employer-initiated termination (without just cause), employee resignation due to employer misconduct, military service, retirement, or death. Employees need at least 1 year of continuous service to qualify. The H1 2026 ceiling per year of service is TRY 64,948.77.
Can I terminate an employee in Turkey without a reason?
No. Turkey requires valid grounds for termination for employees at workplaces with 30 or more employees who have at least 30 days of service. If termination lacks valid grounds, the employee can claim reinstatement or 4 to 8 months’ compensation through a labor court (after mandatory mediation). At smaller workplaces or during probation, the protections are lower, but proper process still applies.
What is SGK and what do employers pay?
SGK is the Social Security Institution (Sosyal Güvenlik Kurumu). Every employee in Turkey must be registered with SGK before their first day of work. The standard employer SGK contribution rate in 2026 is 22.75% of insurable earnings, though eligible employers can reduce this to 18.75%–21.75% through Turkey’s government incentive programs.
Do foreign employees need a work permit in Turkey?
Yes. Non-Turkish citizens require a valid work permit before starting work in Turkey. The employer applies through the e-İzin portal. Processing takes approximately 30 working days. Minimum salary thresholds apply depending on role level (TRY 66,060 to TRY 165,150 per month in 2026, with engineers and architects at TRY 132,120). Employing someone without a valid permit carries administrative fines and potential deportation of the employee.
What is KVKK and does it apply to my company?
KVKK is Turkey’s data protection law, broadly aligned with GDPR. It applies to any company processing personal data of individuals in Turkey, including employee data. Employers must have a lawful basis for processing employee data, manage cross-border transfers carefully, and register with VERBİS if they have more than 50 employees. Consent is only required for sensitive personal data (health records, biometrics).
What changed in Turkish employment law in 2026?
The main 2026 change is Law No. 7566, effective 1 January 2026. It raised the SGK earnings ceiling from 7.5 times the minimum wage to 9 times the minimum wage, increased the Invalidity, Old Age, and Death premium employer share from 11% to 12%, and reduced the Treasury incentive from 4 points to 2 points for non-manufacturing employers. The 2026 minimum wage is TRY 33,030 gross per month, a 27% increase from 2025.
Key Takeaways
- Turkish employment law is governed primarily by Labor Law No. 4857 and is employee-protective by design. Statutory minimums cannot be contracted out of.
- Law No. 7566 (effective January 2026) raised the SGK earnings ceiling to 9× minimum wage, increased the employer Invalidity, Old Age, and Death premium share to 12%, and reduced the non-manufacturing Treasury incentive from 4 points to 2 points.
- Fixed-term contracts without objective justification automatically convert to indefinite-term contracts under Turkish law. This is a trap that catches many foreign employers using generic EOR templates.
- Severance pay is 30 days of gross salary per year of service and accrues from day one. For a senior employee on a high salary, this is a material liability.
- SGK incentive optimization can reduce effective employer rates from 22.75% to 18.75%–21.75%. Most foreign employers using generic EOR platforms never access this.
- KVKK requires careful handling of employee data, especially for cross-border transfers, and registration with VERBİS for employers with more than 50 employees.
Turkey Employment Law in 2026: The Bottom Line
Turkish employment law rewards employers who prepare and penalizes those who rely on generic platform templates. The fixed-term trap, the SGK earnings ceiling change, the Invalidity, Old Age, and Death premium increase, mandatory mediation, and KVKK cross-border obligations are all areas where a boilerplate approach fails.
The employers we see navigate this well share one trait: they have a named Turkish specialist who reads the SGK genelgeleri, not a platform update that arrives three weeks late. Datassist has been that specialist for foreign companies operating in Turkey since 1999. We manage payroll for 500+ clients, calculate 1.5 million payrolls per year, and hold ISO 27001 and ISAE 3402 certifications.
