A professional employer organization (PEO) supports defined employer functions, commonly through US co-employment arrangements. For Turkey hiring, confirm who legally employs the worker, what services are supplied and which authorisations apply; a PEO or EOR label alone does not establish the legal structure.
Here is the part most vendor material leaves out. A PEO is a specific legal construct that exists under United States law. Turkish law has no equivalent. Any proposal that promises you a co-employment compliance shield in Turkey is describing something the Turkish Labour Code does not recognise. Datassist has operated Turkish payroll since 1999 and coordinates partner-managed payroll services across MENA, and this is the single most common misunderstanding we correct during procurement.
This guide explains what a professional employer organization really is, how co-employment works where it is actually codified, why that model does not transfer to Turkey, and which of the three structures Turkish law does recognise fits your expansion.
What a Professional Employer Organization Actually Means
A professional employer organization is a US business model in which an external provider assumes defined employer responsibilities for another company’s workforce. The defining feature is co-employment: the client keeps operational control of the employees, while the PEO becomes the employer of record for payroll tax and statutory filing purposes.
The model has real legal scaffolding in the United States. Most states operate PEO registration or licensing regimes, and at federal level the IRS certifies Certified Professional Employer Organizations under Internal Revenue Code section 3511, which can make the CPEO the employer for federal employment taxes on remuneration it pays to qualifying worksite employees. This treatment depends on the statutory requirements; it is not a transfer of every employment obligation. That statutory backing is what makes the arrangement meaningful rather than contractual wishful thinking.
The industry is substantial. According to NAPEO research published in October 2025, 187 member PEOs serve more than 230,000 small and mid-sized businesses employing over 4.5 million people, representing roughly 15 percent of US employers with 10 to 499 staff. More than 500 PEOs operate in the US overall.
A typical PEO offering bundles payroll processing and employer payroll tax filing, benefits administration, HR compliance support, workers’ compensation coverage, workplace safety consulting, workforce management technology and training programmes. The commercial logic is pooling: a PEO aggregates employees across hundreds of clients to negotiate better insurance rates and spread compliance and insurance costs across a large base.
Definition: PEO and co-employment are US legal constructs. They rest on state PEO statutes and IRS section 3511 certification. Neither the term nor the liability structure has a counterpart in Turkish employment legislation.
How Co-Employment Works in the United States
Under a US co-employment agreement, employer responsibilities divide into two domains. The client is the operational employer: it directs the work, sets compensation, manages performance and makes hiring and termination decisions. The PEO is the administrative employer: it processes payroll, files employment taxes under its own tax identification number, administers benefits and handles statutory reporting.
Client responsibilities typically cover:
- Hiring and termination decisions
- Compensation levels and performance reviews
- Work assignments, schedules and operational direction
- Product, sales, marketing and service delivery
- Strategic and budget decisions
PEO responsibilities typically cover:
- Payroll calculation, processing and disbursement
- Tax withholding and employer payroll tax filings
- Benefits enrolment, administration and carrier coordination
- Workers’ compensation coverage and claims management
- HR compliance monitoring and policy updates
- Statutory reporting and employee records retention
The split works because US law says it works. Take away the state registration regime and the section 3511 liability transfer, and what remains is a services contract with a paragraph asserting shared employer status. That paragraph does not bind a foreign labour court.
Why Co-Employment Does Not Exist in Turkish Law
There is no PEO regime in Turkish legislation. Nothing in Labour Law No. 4857, Social Security Law No. 5510 or Employment Agencies Law No. 4904 creates a licensed status in which a provider and a client are deliberately co-employers of the same worker with a shared compliance liability split. A contract that says otherwise does not create the status it describes.
Turkish law does contain a concept called birlikte istihdam, which translates as co-employment, and this is where most of the confusion starts. It is not a statute and it is not a product. It is a doctrine developed by the Court of Cassation and applied to group companies where one worker in practice serves several affiliated employers. When a court finds it, the consequence is joint and several liability of all of those companies for the worker’s claims, usually alongside findings of organic link or piercing the corporate veil.
Read that consequence again. Turkish co-employment is a liability finding imposed on companies retrospectively in litigation. It is a risk you want to avoid, not a service you buy. A vendor selling you co-employment in Turkey is selling you the name of an adverse court outcome.
Risk: If you sign a Turkey engagement structured as informal worker supply, the realistic outcomes are a finding of muvazaa (simulated subcontracting) under Labour Law 4857 article 2, joint and several liability, or unlicensed worker supply. In each case the worker is typically deemed your direct employee from the start of the engagement, with full back-dated entitlements.
The Three Structures Turkey Actually Recognises
Once co-employment is off the table, the choice narrows to three real options.
Option 1: Your Own Entity With Outsourced Payroll
You establish or already hold a Turkish legal entity. You remain the sole legal employer. A provider runs payroll calculation, SGK filings, statutory reporting and HR administration on your behalf. Liability for employment obligations stays with you, which is precisely why the quality of the calculation and filing work matters. This is the closest functional equivalent to what a US PEO delivers, minus the liability transfer that US statute provides and Turkish statute does not.
Option 2: Employer of Record
An arrangement marketed as EOR normally names the provider’s Turkish entity as the contractual employer. That label does not itself establish that the arrangement is lawful or transfer every employment obligation. Confirm the actual working relationship, registrations, any employment-agency or temporary-supply authorisation requirements, and each party’s statutory responsibilities with qualified Turkish counsel before hiring.
Option 3: Temporary Supply Through an İŞKUR-Licensed Agency
Labour Law 4857 article 7, as amended by Law No. 6715 in 2016, permits worker supply only through a private employment agency holding a specific İŞKUR authorisation, and only in enumerated situations such as contract suspension, seasonal agricultural work, domestic services, urgent occupational health and safety work, or temporary capacity increases. The limits are tight: duration and renewal limits that depend on the statutory ground. For several grounds the initial limit is four months; permitted renewals cannot exceed eight months in total. Some grounds have different rules, and the quarter-headcount limit applies to a specified temporary-capacity ground rather than every arrangement. The agency remains the legal employer throughout. This structure cannot host an open-ended full-time hire.
| Criterion | Own entity plus outsourced payroll | Employer of record | İŞKUR temporary supply |
|---|---|---|---|
| Who is the legal employer | You, solely | Provider named in contract; legal status requires review | The licensed agency |
| Turkish entity required | Yes | Client entity may not be needed; structure requires review | Depends on the lawful supply arrangement |
| Employment compliance liability | Yours | Depends on applicable law and actual arrangement; not automatically transferred in full | Agency and user undertaking have statutory duties |
| Suitable for permanent roles | Yes | Subject to lawful structure review | Ground-specific temporary use |
| Duration limit | Employment contract and law apply | Subject to lawful structure review | Ground-specific duration and renewal limits |
| Headcount limit | None | None | Ground-specific quotas and exceptions |
| Best fit | Established Turkish operations | Market entry without an entity | Genuinely temporary need |
Datassist offers Options 1 and 2. We operate a Turkish legal entity established in 1999, so we can act as employer of record, or run payroll and HR administration against your own entity. What we will not do is describe either arrangement as co-employment, because that would misrepresent your liability position.
What Turkish Payroll Compliance Involves in 2026
Whichever structure you choose, someone has to calculate Turkish payroll correctly.
What Law No. 7566 Changed
Law No. 7566, a tax omnibus law published in the Official Gazette on 19 December 2025 (issue 33112), changed three payroll parameters with effect from 1 January 2026.
First, the SGK insurable earnings ceiling rose from 7.5 times the gross minimum wage to 9 times. With a 2026 gross minimum wage of TRY 33,030 per month, the monthly ceiling is now TRY 297,270. Employees earning above the old cap now contribute on a higher insurable base.
Second, the invalidity, old age and death branch rose by one percentage point, from 20 to 21 percent of insurable wages. The employee share stays at 9 percent and the employer share moves from 11 to 12 percent.
Third, the general private-sector premium reduction under Social Security Law 5510 article 81 was cut from 4 points to 2 points for non-manufacturing employers. This continues a sequence rather than starting one: the reduction went from 5 points to 4 points under Law No. 7538 in January 2025, and from 4 to 2 in January 2026. Manufacturing was carved out both times and retains the 5-point reduction under a temporary article of Law 5510, currently through 31 December 2026. SGK applies the rate automatically from the workplace’s registered NACE code.
2026 Employer Contribution Rates
The resulting 2026 employer rates:
| Case | Employer SGK | Unemployment insurance | Total employer rate |
|---|---|---|---|
| No reduction applied | 21.75% | 2.00% | 23.75% |
| Non-manufacturing, 2-point reduction | 19.75% | 2.00% | 21.75% |
| Manufacturing, 5-point reduction | 16.75% | 2.00% | 18.75% |
Note that the reduction is not automatic entitlement. It requires timely premium filing and payment, no outstanding SGK debt across Türkiye or a current restructuring plan in good standing, and no unregistered or fictitious workers. Losing eligibility moves an employer straight back to 23.75 percent.
Severance Pay and the Real Ceiling
Severance pay is where foreign employers most often budget wrongly. Under Law No. 1475 article 14, which remains in force through Labour Law 4857 provisional article 6, an employee with at least one year of service receives 30 days of gross wages for each year of service in qualifying termination scenarios. The calculation base is the giydirilmiş gross wage, meaning it includes regular benefits, not just base salary.
The cap is not linked to the minimum wage. It is tied to the maximum retirement gratuity payable for one year of service to the highest-ranking civil servant, and it is recalculated twice a year with the civil servant salary coefficient. For 2026 the ceiling is TRY 64,948.77 per year of service from 1 January to 30 June, and TRY 73,729.87 from 1 July to 31 December. The ceiling that applies is the one in force on the termination date.
Common error: Some vendor material states the severance cap as 30 times the minimum wage. Thirty times the 2026 minimum wage would be TRY 990,900, roughly thirteen times the actual ceiling. If your Turkey cost model uses that figure, every severance accrual in it is wrong by an order of magnitude.
Work Permits for Foreign Nationals
Foreign nationals working in Turkey need a work permit from the Ministry of Labour and Social Security, through its Directorate General of International Labour Force. Under International Labour Force Law No. 6735 article 7, a complete application must be concluded within thirty days. In practice the timeline extends when the Ministry requests missing documents, since a deficiency-completion period can be granted. Applications run through calismaizni.gov.tr, and the sponsoring employer must be the entity that legally employs the worker.
Choosing Your Turkey Structure
Start with entity status, because it eliminates options fastest.
If you have no Turkish entity, evaluate a provider-employment arrangement with Turkish counsel before using it. Confirm the lawful employment or agency structure, authorisations and client responsibilities rather than assuming that an EOR contract guarantees compliance or removes your liability. If you later decide to establish your own entity, plan the transition deliberately: moving employees from an EOR to your own payroll requires an employment transfer with employee notification and fresh SGK registration.
If you have a Turkish entity or intend to establish one, outsourced payroll against your own entity gives you the most control and the lowest ongoing service cost, at the price of retaining employment liability yourself. Establishing a Turkish company requires minimum capital of TRY 50,000 for a limited liability company or TRY 250,000 for a joint stock company, both effective since 1 January 2024 under Presidential Decree No. 7887. Companies already below those thresholds must top up by 31 December 2026. There is no statutory service level for commercial registry incorporation, so treat any specific day count from a vendor as an estimate rather than a commitment.
If your need is genuinely short term and fits the statutory grounds, use an İŞKUR-licensed agency and respect the duration and quota limits. If your need is a permanent role, this option is not available to you regardless of how it is packaged.

Frequently Asked Questions
Can I use a PEO in Turkey?
Not in the US sense. Turkish law has no PEO registration regime and no statutory co-employment status, so a contract cannot create a shared employer relationship with a split compliance liability. Providers marketing “Turkey PEO” are almost always offering either employer of record services, in which their entity is the sole legal employer, or payroll and HR outsourcing against your own entity. Ask which structure is proposed, in writing, and have its legality and allocation of statutory duties reviewed before signing.
What is the difference between a PEO and an EOR?
A PEO operates a co-employment model under US law, where the client and the PEO share employer responsibilities and a qualifying CPEO may take on specified federal employment tax liability under IRS section 3511. An EOR service typically names a local provider as the contractual employer. Its validity, authorisation requirements and the client’s remaining duties must be checked under local law. A contract naming one employer is not, on its own, proof that the Turkey arrangement is lawful.
Who legally employs my staff if I use a Turkish provider?
It depends entirely on the structure. Under a proposed EOR arrangement, identify the entity on the employment contract and SGK registrations, then verify the actual structure and remaining obligations under Turkish law. Under payroll outsourcing against your own entity, you are the sole legal employer and the provider is a service supplier. There is no third option in which both of you are employers by design. If a court later finds that both of you functioned as employers, that is the adverse birlikte istihdam outcome, and it brings joint and several liability rather than a tidy split.
What happens to severance pay?
Severance accrues during employment at 30 days of giydirilmiş gross wages per year of service, subject to the statutory ceiling of TRY 64,948.77 per year for terminations in the first half of 2026 and TRY 73,729.87 in the second half. It is an employment cost, so it flows economically to whoever bears the employment relationship. Under an EOR the cost is billed to you but the EOR owns the calculation and payment mechanics. Under your own entity you own both. Accrue it monthly rather than discovering it at termination.
What did Law No. 7566 change for my 2026 payroll?
Three things, all effective 1 January 2026. The SGK insurable earnings ceiling moved from 7.5 to 9 times the minimum wage, giving a monthly cap of TRY 297,270. The invalidity, old age and death branch rose from 20 to 21 percent, with the employer share moving from 11 to 12 percent. The general premium reduction for non-manufacturing employers fell from 4 points to 2 points, leaving manufacturing on 5 points through the end of 2026. Our full breakdown is in Turkey Law 7566: what changed in 2026 payroll.
What is the total employer cost on top of gross salary in Turkey?
For 2026, employer SGK premiums are 21.75 percent of insurable gross with no reduction applied, plus 2 percent unemployment insurance, giving 23.75 percent. A non-manufacturing employer qualifying for the 2-point reduction pays 21.75 percent all in, and a manufacturing employer with the 5-point reduction pays 18.75 percent. Severance accrual sits on top of these figures and is frequently omitted from vendor cost comparisons.
How long does a Turkish work permit take?
International Labour Force Law No. 6735 article 7 requires the Ministry of Labour and Social Security to conclude a complete application within thirty days. The clock runs from submission of a complete file, so incomplete applications restart the practical timeline. Budget for longer than thirty days if the employee’s credentials require translation, apostille or professional recognition.
Can one provider cover Turkey and the wider MENA region?
The legal employment structure has to be established country by country, because each jurisdiction defines the employer separately. What can be consolidated is the commercial and operational layer: one contract, one platform, one accountable contact, with locally compliant employment structures underneath. Datassist runs Turkey payroll directly from Istanbul and coordinates UAE, Saudi Arabia, Qatar and Egypt through our service delivery platform.
Key Takeaways
- A professional employer organization is a US legal construct backed by state registration regimes and IRS section 3511 certification. Co-employment means something specific there because statute makes it mean something.
- Turkish law has no PEO regime and no contractual co-employment status. The Turkish term birlikte istihdam describes a court finding of joint and several liability imposed on companies in litigation, which is a risk rather than a service.
- Turkey recognises three structures: your own entity with outsourced payroll administration, a provider-employment arrangement subject to lawful structure review, and temporary supply through an İŞKUR-licensed agency within strict duration and quota limits.
- Law No. 7566 changed 2026 payroll from 1 January: the SGK ceiling moved to 9 times the minimum wage at TRY 297,270 monthly, the invalidity, old age and death branch rose to 21 percent, and the non-manufacturing premium reduction fell to 2 points while manufacturing keeps 5 points through 2026.
- Severance is capped at TRY 64,948.77 per year of service in the first half of 2026 and TRY 73,729.87 in the second half, tied to the civil servant retirement gratuity and not to the minimum wage. Cost models built on a minimum-wage multiple are wrong by roughly thirteen times.
The Bottom Line
A PEO quote for Turkey should trigger a structure check rather than a decision based on terminology. Ask each provider to identify the contractual employer, actual service scope, authorisations and responsibilities under Turkish law before comparing proposals.
The practical options depend on your entity status, the actual working relationship and the lawful employment or service structure. Compare a reviewed provider-employment arrangement with payroll administration for your own entity, while checking any agency or temporary-supply conditions that apply. Each proposed arrangement should be priced, audited and reviewed for its lawful structure. A service label or contractual responsibility split cannot override statutory duties or the facts of the working relationship.
Datassist has operated Turkish payroll since 1999 from a Turkish legal entity, with an Istanbul-based team that tracks Official Gazette publications and implements regulatory changes on the effective date rather than after an audit finds the gap. If you want structural clarity instead of procurement confusion, start with which structure actually applies to you.
