Turkey Updates Minimum Labor Regulations
Turkey has introduced important amendments to its social security regulations through the Regulation Amending the Social Insurance Transactions Regulation, published in the Official Gazette on May 16, 2026.
The new rules significantly impact Turkey Minimum Labor investigations, construction projects, public tenders, and social security compliance procedures.
These changes are particularly relevant for construction companies, investors, contractors, payroll professionals, and businesses operating in Turkey.
Turkey Minimum Labor Investigation Process Clarified
One of the most important updates concerns the scope of Turkey Minimum Labor investigations.
Under the revised framework, the Social Security Institution (SSI) may evaluate:
- Public tender projects;
- Private construction projects;
- Information obtained from public authorities;
- Official documents and records.
The objective of these Turkey Minimum Labor investigations is to determine:
- Whether a minimum labor calculation is required;
- Whether sufficient labor has been reported;
- Whether any social security premium liabilities remain unpaid.
Multiple Construction Projects Under One SSI Registration
The new regulation simplifies certain procedures for construction companies.
Under specific conditions, multiple construction projects may now operate under a single SSI registration number for Turkey Minimum Labor purposes.
This option may be available when:
- Construction sites are adjacent or located close to each other;
- The same employer carries out the projects;
- Employees work across multiple projects;
- The application is submitted within six months of the first project’s commencement.
This change may reduce administrative burdens for large-scale construction operations in Turkey.
New Investigation Method for Tender Projects
Turkey has also introduced a new approach for Turkey Minimum Labor investigations relating to public tenders and contract-based projects.
Where provisional acceptance has been completed but the final contract value has not yet been determined:
- Employers may request an investigation based only on paid progress payments;
- SSI may conduct a partial review;
- No clearance certificate will be issued at this stage.
This amendment provides additional flexibility during project completion phases.
Clearer Definition of Project Completion Dates
The new regulation also clarifies the completion date used for Turkey Minimum Labor assessments.
According to the revised rules:
- If no deficiencies exist, the provisional acceptance date becomes the completion date;
- If deficiencies are identified, the completion date becomes the date on which corrections are finalized;
- For projects without an acceptance procedure, the completion date is determined by the relevant authority.
This clarification helps reduce uncertainty during SSI reviews.
New Rules for Cancelled or Incomplete Tenders
For incomplete or terminated projects, the SSI has introduced new Turkey Minimum Labor procedures.
Under the new system:
- Investigations will be based solely on payments already made;
- If no payment has been issued, no minimum labor investigation will be conducted.
This provides greater predictability for contractors involved in cancelled public projects.
Revised Construction Cost Calculation Method
The calculation methodology used in Turkey Minimum Labor assessments for private construction projects has also changed.
For projects completed within a single year:
- The unit construction cost applicable on the completion date will be used.
For projects spanning multiple years:
- The arithmetic average of annual construction unit costs between the start date and completion date will be applied.
This new approach aims to create a more accurate and balanced assessment system.
SSI May Launch Ex-Officio Investigations
One of the most significant changes concerns dormant construction files.
Under the new regulation, the SSI may initiate an ex-officio Turkey Minimum Labor investigation where:
- A construction file remains open;
- The project has not been abandoned or liquidated;
- No insurance declarations have been submitted for at least two years.
This provision increases compliance obligations for employers and construction investors in Turkey.
Impact on Employers and Investors in Turkey
The new Turkey Minimum Labor rules directly affect:
- Construction companies;
- Real estate developers;
- Foreign investors;
- Public contractors;
- Payroll and HR departments;
- Employer of Record (EOR) providers.
Businesses should review their SSI registration procedures, labor reporting practices, and social security compliance processes to ensure full compliance with the updated regulations.
The 2026 reform introduces substantial changes to Turkey Minimum Labor investigations and construction-related SSI procedures.
With new rules governing project consolidation, cost calculations, tender investigations, and dormant construction files, employers operating in Turkey should carefully assess the impact of these changes on their compliance obligations.
Understanding the latest Turkey Minimum Labor requirements is essential for reducing risk, avoiding social security disputes, and ensuring smooth project management in Turkey.
