Turkey Tax System: Tax Guide for Foreign Companies 2026
This guide covers the general structure of Turkey's tax system for foreign companies and individuals — corporate tax, personal income tax, and tax residency concepts. It stays at the hub level; for the specific mechanics of VAT/KDV registration and compliance, see our dedicated VAT registration guide. Tax rates and thresholds are revised periodically by the Turkish government, so treat the figures below as a general orientation and confirm current numbers with a certified accountant (mali müşavir) or the Revenue Administration (Gelir İdaresi Başkanlığı, GİB) before making financial decisions.
Corporate Tax
The standard corporate tax rate for companies operating in Turkey is 25% as a general baseline. Certain incentive zones, sectors, or company structures can carry different effective rates or temporary reductions, and these rules change from time to time — verify the applicable rate for your specific business structure directly with GİB or an accountant.
Personal Income Tax
Individual income tax in Turkey follows a progressive bracket system, generally ranging from around 15% at the lowest bracket to 40% at the highest, applied incrementally as income increases through the brackets (not as a single flat rate on total income). The specific bracket thresholds are adjusted periodically, often annually for inflation, so don't rely on a static figure from an older source.
Tax Residency
Whether you're taxed in Turkey on worldwide income or only Turkey-sourced income depends heavily on your tax residency status. Spending more than six months (183 days) in Turkey within a calendar year is a commonly cited practical threshold associated with residency, though the complete legal test can also weigh factors like your permanent home and center of vital interests. Cross-border tax residency questions get complicated quickly — this is an area where individual professional advice matters more than general guidance.
Double Taxation Treaties
Turkey maintains double-taxation avoidance agreements with a large number of countries, generally intended to prevent the same income being fully taxed twice. Whether a specific treaty applies to you, and how, depends on your home country and the type of income involved — this requires individual review rather than a blanket assumption that "a treaty exists so I'm covered."

Conclusion
Turkey's tax system for foreign companies and individuals rests on corporate tax, progressive personal income tax, and residency rules that determine your overall exposure — all periodically revised, so treat specific rates as a starting orientation rather than a fixed fact.

Ofte Stillede Spørgsmål
- What is Turkey's standard corporate tax rate?
- The standard corporate tax rate is 25% as a general baseline, though certain sectors, incentive zones, or company types can have different effective rates. Corporate tax rates are periodically revised by the government, so confirm the current rate with a certified accountant (mali müşavir) or the Revenue Administration (Gelir İdaresi Başkanlığı, GİB) before finalizing financial projections.
- How does personal income tax work in Turkey?
- Individual income tax uses a progressive bracket system, with rates generally ranging from around 15% at the lowest bracket up to 40% at the highest, applied incrementally as income rises. Bracket thresholds are adjusted periodically, often annually, so verify current figures with GİB or an accountant rather than relying on a fixed number.
- What determines tax residency in Turkey?
- Physical presence is a central factor — spending more than six months (183 days) in Turkey within a calendar year is a commonly cited threshold that can trigger tax residency, though the full legal test also considers factors like domicile and center of vital interests. This is genuinely complex in cross-border situations — get personalized advice rather than self-assessing.
- Do double-taxation treaties protect me from being taxed twice?
- Turkey has double-taxation avoidance agreements with a large number of countries, generally designed to prevent the same income from being fully taxed in both Turkey and your home country. Whether and how a specific treaty applies to your situation depends on the country and the type of income involved — this needs individual review, not a generic assumption.
