As established in Part 1 (The Master Guide), Double Taxation Avoidance Agreements (DTAA) do not trigger automatically. For a Turkish corporation to deduct (credit) taxes paid abroad from its Turkish tax liability, it must fulfill a strict bureaucratic procedure determined by the Revenue Administration. This process is regulated by Article 32 of the Corporate Tax Law (KVK) and relevant general communiqués. Mismanagement of this process leads to serious cash flow issues and forfeiture of rights.
The Core Mechanism: Foreign Tax Credit (KVK Art. 32)
Taxes paid locally (in the Source Country) by corporations that are full taxpayers in Turkey on earnings derived from foreign activities can be credited against the Corporate Tax assessed in Turkey on these earnings.
Critical Limit: The amount of foreign tax to be credited cannot exceed the amount found by applying the Turkish corporate tax rate (25%) to the foreign income under any circumstances.
The 5-Step Credit and Documentation Process
This process must be managed simultaneously with tax authorities in both Turkey and the counterpart country.
Step 1: Obtaining “Certificate of Residence” from Turkey
First, you must prove to the foreign (source country) tax administration that you are a taxpayer in Turkey. To do this, you must apply to the Revenue Administration (GİB) or the Large Taxpayers Tax Office and obtain an official “Certificate of Residence” showing that you are a Turkish resident for that year.
Step 2: Paying Reduced Tax Abroad
You must present the Certificate of Residence you obtained to your customer or the tax office abroad to request the application of reduced withholding tax rates stipulated in the DTAA (e.g., 10% instead of 20%).
Step 3: Obtaining Proof of Foreign Tax Payment
After the tax is withheld abroad, an official document proving that the tax has been paid (e.g., Tax Clearance Certificate, Withholding Tax Receipt) must be obtained from the competent authorities of that country (Tax Office or Consulate). This document must clearly show the type of tax, the amount, and the income it relates to.
Step 4: Apostille and Translation (Vital Stage)
For this official payment document obtained from abroad to be valid in Turkey:
- It must be approved by the Turkish Consulate in that country OR an “Apostille” must be obtained for countries party to the Hague Convention.
- Then, a notarized sworn translation must be made in Turkey.
Step 5: Claiming Credit in the Tax Return
Once all these documents are completed, a credit claim is made in the Corporate Tax Return for the relevant accounting period on the line “Portion to be Credited from Taxes Paid in Foreign Countries.” Documents are kept for submission upon request or submitted as an attachment to a petition to the tax office.
Critical Warning: Timing and Statute of Limitations
The credit for foreign taxes must be made in the Corporate Tax return for the period in which the relevant income is taxed in Turkey. If the procurement of documents is delayed, the return is submitted normally, and a “Correction Return” is filed to claim the credit once documents are complete. However, if this right is not used by the end of the fifth year following the year in which the tax originated, it becomes statute-barred.
Frequently Asked Questions
Can I claim a credit during Provisional Tax periods?
Yes. Taxes paid abroad can be credited in the Provisional Tax returns (Geçici Vergi) of that year, without waiting for finalization at the end of the year, provided they are documented.
Is Apostille approval mandatory?
Yes. If the country where the document is obtained is a party to the Hague Convention, Apostille is mandatory. If not, the approval of the Turkish Consulate in that country is required. Credit transactions made with unapproved documents are rejected during audits.
What is the limit for the foreign tax credit?
The credit cannot exceed the amount calculated by applying the Turkish Corporate Tax rate (currently 25%) to the foreign income. If the foreign tax rate is higher, the excess cannot be refunded or carried forward.
