Turkey

Turkey has an active and growing crypto market — one of the highest retail adoption rates globally by population — but its tax framework remains underdeveloped. There is no dedicated cryptocurrency tax law. Crypto gains are taxed under general income tax principles, but the Gelir İdaresi Başkanlığı (GIB, Revenue Administration) has not issued comprehensive crypto-specific guidance covering disposal gains, DeFi, or staking. The Capital Markets Board (SPK) regulates crypto exchanges under rules introduced in 2024, which brought Turkey's exchange sector under formal oversight for the first time. The Financial Crimes Investigation Board (MASAK) oversees AML compliance.

The absence of specific guidance creates genuine ambiguity. What is clear is that Turkey does not recognise a capital gains category for crypto — gains are treated as income. What remains unclear is the precise triggering mechanism, applicable deductions, and the treatment of crypto-to-crypto transactions under the current framework.

Core Tax Treatment

Cryptocurrency gains in Turkey are taxed as ordinary income under the general income tax schedule, at progressive rates of 15–40%. There is no holding period benefit, no annual exemption, and no flat rate for investment gains. Gains are calculated in Turkish lira (TRY) at the exchange rate at the time of disposal, which creates a significant complication: Turkey's high inflation rate means that nominally large TRY gains can reflect little or no real gain in USD or EUR terms, yet remain fully taxable in lira.

Crypto payments have been banned since April 2021 — it is illegal to use cryptocurrency as a means of payment for goods and services in Turkey. Trading on exchanges is legal and regulated. Holding is legal. The payments ban does not affect the tax treatment of trading activity.

The Payments Ban in Context

The 2021 Central Bank regulation prohibiting crypto payments does not criminalise trading or holding. Turkish residents trade actively on both local SPK-licensed exchanges and international platforms. The ban does, however, restrict the practical use cases for crypto in Turkey and means that on-chain spending cannot be used as a disposal mechanism in the way it can in other jurisdictions.

Exchange Regulation

The SPK's 2024 crypto exchange licensing regime requires Turkish exchanges to obtain authorisation, maintain minimum capital, segregate client assets, and implement AML programmes. Only SPK-licensed platforms may operate for Turkish retail users. The regulatory framework is relatively new and enforcement is still maturing, but the licensing requirement has formalised the sector significantly. International exchanges without Turkish licences are accessible but operate in a legally ambiguous space for Turkish users.

Inflation and TRY Valuations

Turkey's chronically high inflation rate — which has exceeded 70% annually in recent years — creates a structural distortion in crypto tax calculations. A gain measured in TRY may appear substantial in nominal terms while representing a loss or minimal gain in real purchasing power terms or in hard currency. Turkish tax law does not currently provide an inflation adjustment mechanism for crypto gains. This means taxpayers may owe income tax on paper gains that do not reflect real economic enrichment — a problem that applies to all TRY-denominated investments but is particularly acute for crypto given its volatility against both TRY and USD.

Reporting

Crypto gains are declared in the annual income tax return (GIB Beyannamesi), filed by 31 March for the prior calendar year. There is no crypto-specific reporting form; gains are included in the general income declaration. MASAK AML obligations apply to exchanges and require reporting of suspicious transactions and large cash movements. Turkey has committed to CARF by 2027, which will formalise exchange reporting obligations.
