• TRY 200,000 – 2,000,000: A written explanation of at least 20 characters is mandatory, clearly stating the type and source of the transaction.
• TRY 2,000,000 – 20,000,000: Completing the Cash Transaction Declaration Form (CTDF) is mandatory (including identity, profession, transaction type, asset type, amount, source, supporting documents, and signatures).
• TRY 20,000,000 and above: Additional information and documents on the source of funds must be provided (e.g. sales contracts, inheritance documents, notarized deeds).
