SGK Employer Registration in Turkey: Workplace Setup & Payroll Guide

A Turkish company does not open an SGK workplace file merely because it has been incorporated. The obligation normally arises when it becomes an employer of a person who must be reported under the employee insurance category, commonly called 4/a.

Before the first working day, the company must coordinate three separate compliance layers: the SGK workplace registration, the employee’s insurance entry notice and a payroll file consistent with the employment contract, work permit and tax records. Completing only one layer does not cure a missing or late filing in another.

This guide explains the core workflow under Social Insurance and General Health Insurance Law No. 5510, including foreign-worker cases, monthly Muhtasar ve Prim Hizmet Beyannamesi reporting and the limits of an SMMM’s authorization.

When an SGK Workplace File Is Required

Law No. 5510 defines a workplace broadly as the place where insured persons carry out their work together with connected places and equipment. Under Article 11, an employer must submit the workplace declaration no later than the date an insured employee starts work.

The trigger is insured employment, not company registration by itself. A newly incorporated LLC with no employees may not yet need a 4/a workplace file. That conclusion should not be extended to every founder or manager without checking status:

• a non-shareholder manager working under an employment relationship may fall within 4/a;
• company partners and shareholder board members can fall under different insurance provisions, including 4/b;
• a salary label alone does not determine the insurance category; and
• a foreigner’s work permit does not by itself decide whether the person is insured under 4/a, 4/b or an applicable international agreement.

Classify founders, directors and managers before payroll is opened. A wrong category can affect both contribution reporting and work-permit compliance.

Workplace Declaration Deadline and Trade Registry Integration

The ordinary Article 11 deadline is the date on which the first insured employee begins work. Filing after that point can create an administrative fine even if the employee entry notice is submitted separately.

Trade Registry Directorates transmit specified incorporation and employment information to SGK for companies registered through the integrated system. Where the legally required employee commencement information is transmitted, that notification can be treated as the workplace declaration. This should not be described as automatic activation for every newly formed LLC or JSC. A company incorporated without employees may still need to open or complete its SGK file when hiring begins.

After electronic registration, SGK may request supporting documents or electronic confirmations within the applicable period. The exact file depends on legal form, representation, address, tender or construction status, sub-employer relationships and the user being authorized. Do not use one universal physical-document checklist for every SGK center.

The resulting workplace identifier is commonly presented as a 26-character SGK workplace registration number. It should be copied directly from the SGK record into payroll and MPHB systems. Manually reconstructing it from assumed tax, hazard or location codes creates avoidable filing errors.

Documents and Information to Prepare

A standard company file may require some of the following items, depending on what SGK can verify electronically:

• trade registry number, MERSİS number and current registry records;
• tax identification and registered-address information;
• the legal representative’s identity and current representation record;
• the first employee’s start date and workplace activity code;
• NACE or business activity information and any special workplace classification;
• authorization for the e-Sigorta user;
• an accounting professional agreement or electronic authorization where the SMMM will file; and
• construction, tender, sub-employer or transfer documents when the workplace has a special status.

A tax plate, Gazette copy, signature circular, lease, passport translation or power of attorney may be requested in a particular file, but not every item is universally required in paper form. Pre-clear the list through the electronic application and the responsible SGK unit.

An SMMM may prepare and transmit registrations and payroll declarations within the professional agreement and electronic authorization. Professional status alone does not make the SMMM the company’s legal representative or authorize every password, signature and employment decision.

Employee Entry Notice: The Standard Rule and Exceptions

Under Article 8 of Law No. 5510, the employer generally submits the Sigortalı İşe Giriş Bildirgesi before the employee starts work. In ordinary office employment, operational practice is to complete it no later than the day before the start date.

There are statutory exceptions, but they are narrow. Examples include same-day reporting rules for specified construction, agriculture or fishing workplaces and a limited rule connected with employees hired when a workplace first becomes subject to workplace-declaration requirements. The startup rule is not a blanket one-month grace period for all new hires, and the phrase “up to one unit” has no place in the test.

Before using an exception, document:

1. the workplace’s legal classification;
2. the actual employment start date;
3. the workplace declaration due date;
4. the exception relied upon; and
5. the electronic submission timestamp.

Late employee entry notices can lead to Article 102 penalties. The amount and possible increase depend on how the omission is identified, whether it is repeated and the minimum wage applicable when the penalty is calculated. Avoid presenting every late notice as one fixed minimum-wage fine.

Foreign Employees: Work Permit and SGK Timing Are Separate

A foreign national generally needs a valid work permit or a documented exemption before working for a Turkish employer. International Labor Force Law No. 6735 governs the permit layer; Law No. 5510 and international social security rules govern insurance reporting.

For a permit issued through a domestic application, the employer is generally expected to complete SGK obligations within 30 days from the permit’s effective start. For a permit obtained through an overseas application, the relevant period is generally measured from the foreigner’s entry into Turkey, subject to the permit’s entry and validity rules.

This 30-day administrative window is not permission to employ the person uninsured. The actual work start, SGK entry notice, payroll commencement and permit validity must agree. If the employee begins earlier than the reported insurance date, the employer can face unregistered-employment findings even though 30 days have not elapsed.

A valid work permit is generally treated as a residence permit under the applicable immigration rules, subject to statutory exceptions. It does not remove the employer’s SGK, payroll, tax or occupational-safety duties.

For permit categories and employer criteria, see our work permit guide for Turkey.

Current Foreign-Worker Salary Criteria

Work-permit salary criteria are not fixed permanently in Law No. 5510. They are published and applied by the Ministry of Labour and Social Security and can change. Under the Ministry’s current evaluation criteria, the general gross salary thresholds include:

The former 6.5-times statement for senior executives is outdated. Sector-specific rules, exemptions and special foreigner categories may produce a different result, so confirm the criterion applicable on the filing date.

The salary stated in the work-permit application, employment contract, payroll, bank payment and SGK contribution base should be reconciled. SGK premiums are calculated on the legally reportable earnings base, subject to the statutory floor and ceiling. A work-permit salary threshold should not be described as a separate SGK premium rate.

Temporary Assignments and Social Security Agreements

Turkey’s bilateral and multilateral social security arrangements can allow a temporarily assigned employee to remain covered in the sending state for a defined period. The exemption is not automatic and should not be summarized as a universal one-to-three-year A1 exemption.

The applicable agreement determines:

• whether the employee and employer are covered;
• the initial posting period and any extension procedure;
• which institution issues the certificate;
• the correct bilateral certificate code; and
• which Turkish insurance branches remain applicable.

An A1 is associated with European coordination systems and is not the correct certificate name for every country that has an agreement with Turkey. Each agreement uses its own forms and conditions. Keep the original or electronically verifiable coverage certificate in the payroll file before treating the assignment as exempt from Turkish long-term insurance.

Workers sent from a country without an applicable agreement must be assessed under Turkish legislation and the limited temporary-assignment rules. Citizenship alone does not create an exemption.

e-Sigorta Access and Responsibility

After the workplace record is established, the employer designates the user who will access the relevant SGK employer services. Current processes rely heavily on e-Devlet and electronic authorization, so a guide should not promise that every company receives a physical password token or must collect credentials at the SGK counter.

Separate the following roles:

• employer and legal representative: decides employment, salary, start and termination;
• e-Sigorta user: operates the authorized SGK screens;
• SMMM: calculates payroll and submits authorized declarations under the professional agreement; and
• HR or payroll contact: supplies attendance, leave, benefits and personnel changes.

The employer remains responsible for accurate and timely reporting even where an SMMM or outsourced payroll provider submits the file. Internal deadlines should therefore precede statutory deadlines.

MPHB Filing and Payment Calendar

The Muhtasar ve Prim Hizmet Beyannamesi, or MPHB, combines withholding-tax information and monthly insurance service data in one electronic declaration. Combining the data does not combine every payment deadline.

For a normal monthly payroll period:

1. Payroll inputs close. Confirm attendance, overtime, leave, benefits, hires, terminations and court or enforcement deductions.
2. Contribution bases are calculated. Apply the correct employee and employer shares, statutory floor and ceiling, incentive code and missing-day reasons.
3. MPHB is submitted. The standard monthly deadline is the 26th day of the following month, subject to official deadline extensions and holiday rules.
4. Withholding tax is paid. The tax payment normally follows the MPHB tax deadline, generally the 26th.
5. SGK premiums are paid separately. Monthly premiums are generally due by the end of the following month, subject to the statutory calendar and holiday rules.

The original statement that both SGK premiums and payroll taxes are paid on the last business day was incorrect. Filing, tax payment and SGK payment should appear as separate controls in the compliance calendar.

2026 Contribution Rates and Incentive Caution

For employees under the ordinary private-sector 4/a structure, the baseline rates as of this review include:

• employee SGK share: 14%;
• employee unemployment insurance: 1%;
• employer SGK share before incentives: 21.75%; and
• employer unemployment insurance: 2%.

These percentages do not show the entire payroll cost. Income tax, stamp tax, benefits, minimum-wage support, contribution ceilings, incentive eligibility and sector-specific rules can change the result. See our 2026 employer cost guide for the broader calculation.

The Ministry’s official 2026 minimum-wage cost table shows a 16.75% employer SGK share for qualifying manufacturing workplaces using the five-point reduction, 19.75% for qualifying workplaces in other sectors using the two-point reduction, and 21.75% where no reduction applies. The 2% employer unemployment contribution remains separate in each example.

These reductions are conditional, not automatic. The employer must satisfy the current debt, filing, payment, employment-record and incentive-code conditions for the relevant month. Other incentives may use different bases, combinations or duration rules.

Current SGK guidance and the workplace’s monthly eligibility record should be checked before an incentive code is selected.

Practical Employer Registration Workflow

1. Classify the working persons. Determine whether founders, partners, board members, managers and employees fall under 4/a, 4/b or an international-agreement rule.
2. Set the real start date. Do not let the employment contract, work permit, SGK notice and payroll use different dates.
3. Open or complete the workplace record. File by the Article 11 deadline and verify whether trade registry integration supplied all required information.
4. Confirm the workplace number and activity. Check the number, NACE, address, legal form and any special workplace classification in the SGK record.
5. Authorize electronic users. Complete the applicable e-Sigorta and professional authorizations without sharing personal portal credentials informally.
6. Submit employee entry notices. Use the standard pre-start deadline unless a documented statutory exception applies.
7. Reconcile foreign-worker files. Match work permit salary, start date, insurance status and any international coverage certificate.
8. Operate the monthly close. Collect payroll inputs early enough for review before MPHB and payment deadlines.
9. Retain evidence. Archive electronic receipts, payroll calculations, bank payments, permits, certificates and employee notices.
