Corporate tax in Türkiye: what foreign-owned companies actually pay

Ask what companies pay in Türkiye and you will hear a single number — the headline corporate income tax rate. It is the least interesting part of the answer. What a foreign-owned company actually pays is decided by four layers: the corporate rate, withholding on what leaves the country, VAT on what it sells, and the incentives and treaties that carve pieces out of all three.

Layer one: corporate income tax

Turkish resident companies are taxed on worldwide income; non-residents on Turkish-source income. The general corporate rate has been 25% in recent years (higher for banks and financial institutions), with reduced rates applying in specific cases — for example for export income and for companies newly listing on Borsa İstanbul. Rates in Türkiye move with fiscal policy; before building a business case, confirm the rate for the current year.

Layer two: withholding — the tax people forget

The corporate rate is what the company pays; withholding is what the shareholder feels. Dividends distributed to a foreign parent or individual are subject to dividend withholding; royalties and many service fees paid abroad attract their own withholding. This is where structure matters:

• Profits retained and reinvested in the company bear only corporate tax.
• Profits distributed bear corporate tax first and dividend withholding second — the combined figure is your true burden.
• The withholding rate is frequently reduced by double-taxation treaties; Türkiye's treaty network covers most of Europe, the Gulf and beyond. The country your holding sits in changes your after-tax result.

Layer three: VAT and transaction taxes

The standard VAT rate is 20%, with reduced rates for defined categories. For most operating companies VAT is a cash-flow topic rather than a cost — input VAT is offset against output VAT — but structures that accumulate input VAT (construction, export-heavy models) need planning to avoid trapped VAT. Real estate transactions add title deed fees; some financing transactions attract banking and stamp duties. None of these are exotic, but all of them belong in the model before you sign, not after.

Layer four: the carve-outs

• Technology development zones (teknoparks) and R&D centres: substantial income tax and social security advantages for qualifying software and R&D activity.
• Free zones: exemptions for qualifying manufacturing and export operations.
• Investment incentive certificates: VAT and customs exemptions and reduced corporate tax for qualifying investments, scaled by region and sector.

The pattern we see in practice: foreign investors over-focus on the headline rate and under-use the incentive system. The incentive certificate you did not apply for is the most expensive tax you will pay in Türkiye.

Compliance rhythm: what the year looks like

A Turkish company lives on a fixed calendar: monthly VAT and withholding declarations, quarterly advance corporate tax, the annual corporate tax return, plus payroll and social security filings for every employee. Transfer pricing documentation applies to dealings with related parties abroad — intercompany loans, management fees and royalties are exactly where audits look first.

What this means for your structure

Three questions decide most of your Turkish tax outcome before you earn a single lira: Where does the holding sit (treaty access)? Will profits be distributed or reinvested (withholding exposure)? Does the activity qualify for a zone or incentive (rate carve-outs)? We model these with you at the structuring stage — because after incorporation, every one of them is more expensive to change.
