Permanent Establishment in Turkey for Foreign Companies: Workplace, Permanent Representative, Home Office and Tax Risk

1. A foreign company is a limited taxpayer when both legal and business centres are outside Türkiye

Corporate Tax Law Article 3 distinguishes resident companies from foreign entities whose statutory and business centres are both abroad. The foreign entity is not taxed in Türkiye on worldwide income merely because it sells to Turkish customers.

Instead, Türkiye taxes the income categories that domestic law treats as obtained in Türkiye. Commercial profits produced through a Turkish workplace or permanent representative are a central category.

Treaties can restrict this source taxation further.

2. A Turkish workplace can create corporate-tax nexus without a subsidiary

The law refers to a workplace within the Tax Procedure Law framework. Office, shop, branch, workshop, warehouse, factory, construction site and other places used for business can qualify depending on the facts.

The legal form of occupancy is not decisive. A foreign company can create a workplace even if it rents rather than owns the location.

The key is whether the location is used to conduct the foreign enterprise’s business.

3. The Tax Procedure Law workplace concept is broader than a registered branch

Tax Procedure Law Article 156 defines workplace functionally. A business can therefore create a taxable place before trade-register formalities have been completed.

Failure to register does not prevent the tax authority from finding that a factual workplace existed.

Companies should map actual Turkish premises, storage, desks, project offices and other recurring locations.

4. A permanent representative can create Turkish-source commercial income

Corporate Tax Law Article 3 also incorporates the permanent-representative concept through the Income Tax Law. A person who acts on behalf of the foreign enterprise with a sufficiently permanent commercial role can create Turkish nexus even without a separate office.

Formal job title is not controlling. The actual authority and repeated business activity matter.

A distributor purchasing and reselling on its own account can differ from an agent acting for the foreign principal.

5. Contract authority is a major dependent-agent risk

Many double-tax treaties treat a dependent person who habitually concludes contracts or exercises authority on behalf of the enterprise as a PE trigger, subject to the exact treaty wording.

Modern treaty standards can also focus on persons who habitually play the principal role leading to contracts routinely concluded without material modification.

Sales staff should therefore not be given permanent Turkish commercial authority without tax review.

6. A home office can create risk when it becomes a company business location

An employee working occasionally from a Turkish home does not automatically create a permanent establishment. The inquiry considers permanence, whether the location is effectively at the enterprise’s disposal, whether the company requires or relies on the location and what business functions are performed there.

A dedicated Turkish home office used for years by a senior manager, advertised as a company contact location and funded by the employer presents a stronger risk than optional occasional work.

The employment and tax facts should be documented consistently.

7. Multiple remote employees can create a stronger Turkish presence

A foreign company allowing a substantial team to work indefinitely from Türkiye can develop a factual operating footprint even without leased corporate premises.

Local management, customer meetings, contract authority, equipment and employer-controlled workplaces can increase PE risk.

Our remote-work guide explains the employee tax/work-permit side.

8. A registered Turkish branch normally represents an obvious business presence

A branch is not a separate legal entity from the foreign parent but is registered to conduct business in Türkiye. Its profits attributable to Turkish operations are generally within Turkish corporate taxation.

Branch accounting, withholding on remitted profits and treaty provisions require separate calculation.

Branch versus subsidiary is therefore both a legal-liability and tax-structuring choice.

9. Warehouse and stock presence require functional analysis

A warehouse used only for preparatory or auxiliary storage can receive treaty protection in some agreements, while inventory used for active sales and fulfilment can create stronger PE exposure.

The exact treaty wording matters because OECD/MLI developments have narrowed some traditional exceptions.

What employees and agents do at the warehouse can be as important as the premises themselves.

10. Turkish domestic law contains a purchasing-for-export exception

Corporate Tax Law Article 3 provides a special rule where a foreign entity without its business centre in Türkiye establishes a workplace or representative solely to purchase or manufacture goods for export and does not sell those goods in the Turkish domestic market.

GİB rulings confirm that the profit from such qualifying export purchasing can fall outside Turkish-source commercial income under the stated conditions.

Any Turkish domestic sale or broader function can change the result.

11. Construction sites often use treaty-specific duration tests

Double-tax treaties commonly define a construction, installation or assembly site as a PE only when it lasts beyond a specified period. The threshold differs across treaties.

Projects should not assume a universal 12-month rule. Some Turkish treaties use different periods.

Connected projects and artificial splitting can require aggregation under treaty/anti-avoidance principles.

12. Some treaties contain service-permanent-establishment provisions

Certain Turkish treaties treat furnishing services in Türkiye for a specified number of days as a PE even without a traditional fixed office.

Consulting, engineering and technical projects can therefore create PE based on duration and personnel presence.

Review the exact treaty before deploying teams into Türkiye.

13. Treaty Article 5 can be narrower than Turkish domestic law

Where a double-tax treaty applies, Türkiye generally cannot tax foreign business profits unless the enterprise has a PE within the treaty definition. The treaty can therefore protect a foreign company even where domestic source rules appear broader.

Treaty residence must be documented with the appropriate residence certificate.

Our double-tax treaty guide explains documentation.

14. PE existence does not mean every global profit becomes taxable in Türkiye

Only profits attributable to the Turkish PE are generally taxable. The PE is treated as if it were a distinct enterprise performing its functions and using its assets/risks, subject to Turkish law and treaty principles.

Transfer-pricing and expense-allocation records therefore matter.

Global revenue should not be attributed mechanically to Türkiye merely because a PE exists.

15. Once PE exists, tax registration and compliance must be addressed

A foreign entity can need Turkish corporate-tax registration, books/records, periodic filings and annual returns. The responsible local representative and competent tax office are determined under the tax statutes.

Late discovery of a PE can create past tax, interest and penalty exposure.

Voluntary correction should be evaluated before an audit begins.

16. VAT nexus does not always follow the corporate-tax PE result

Services or supplies can create Turkish VAT or reverse-charge obligations even when the foreign company has no corporate-tax PE. Conversely, a PE can have its own VAT registration.

Corporate income tax, VAT, withholding and payroll/social-security questions should be mapped separately.

A treaty generally governs income taxes, not VAT.

17. Restructuring should be prospective and commercially real

A company that discovers PE exposure should not backdate contracts or pretend existing Turkish operations never occurred. Historical tax liability must be evaluated on actual facts.

Prospective restructuring—local subsidiary, branch, independent distributor, reduced agent authority or remote-work controls—can be considered based on commercial needs.

Conclusion

A foreign company can create Turkish corporate-tax exposure without incorporating in Türkiye. Workplace, permanent-representative, home-office, agent, project and treaty rules determine PE risk. The correct analysis compares Turkish domestic law with the applicable treaty and then attributes only the Turkish PE’s profits, rather than assuming either “no subsidiary means no tax” or “one employee means automatic PE.”
