Stamp tax is one of the most common yet often misunderstood indirect taxes in Turkey. Any document that gains legal validity or represents an official transaction may be subject to stamp tax. In this guide, we cover the documents subject to stamp tax, applicable rates, declaration requirements, and common mistakes in practice.
When and How Does Stamp Tax Arise in Turkey?
According to Law No. 488, stamp tax liability arises when a document is signed or submitted to an official institution. Whether the document is on paper or in electronic form, if it represents a legal transaction, it is subject to stamp tax in Turkey.
The applicable rates and rules are determined under the Stamp Tax Law (Law No. 488), which defines which documents are taxable and at what rate.
Which Documents Are Subject to Stamp Tax in Turkey?
- All types of contracts (service, purchase, consultancy, etc.)
- Lease agreements
- Letters of undertaking and guarantees
- Payrolls and salary receipts
- Tax declarations and notifications
- Arbitration decisions and settlement agreements
However, documents that are internal, have no financial burden, or are unsigned between parties are generally not subject to stamp tax.
Who Is Liable for Stamp Tax in Turkey?
The parties who sign the document — whether individuals or legal entities — are jointly and severally liable for stamp tax. If more than one party signs a contract, all parties bear joint liability, meaning if one fails to pay, the others may be held responsible. Disputes often arise when the tax responsibility is not clearly defined between parties.

Frequently Asked Questions About Stamp Tax Turkey
Is stamp tax required for contract extensions?
If the contract term is extended without a change in monetary value, generally no new stamp tax is due. However, if the contract value increases, tax must be paid on the additional amount.
Is stamp tax payable for each copy of a contract?
Only the original signed copy is subject to stamp tax. If multiple signed originals are prepared and used, each may be taxable. Best practice is to sign and use a single original.
How is stamp tax declared and paid?
Stamp tax becomes due upon signing or enforcement of the document. The declaration must be submitted and paid by the end of the same month. Payment is made via bank or through the Turkish Revenue Administration’s online system.
Do electronic contracts trigger stamp tax in Turkey?
Yes. Electronically signed (e-signature) contracts are fully subject to stamp tax. Declaration and payment are handled through the electronic filing system.
How is stamp tax calculated for foreign currency contracts?
The taxable base is converted into Turkish Lira using the Central Bank’s selling rate on the contract date.
