No Inflation Adjustment Between 2025 and 2027

With Law No. 7571, titled "Law Amending the Turkish Penal Code and Certain Other Laws and Decree Law No. 631", which entered into force upon being published in the Official Gazette dated 25 December 2025 and numbered 33118, it has been stipulated that inflation adjustment shall not be applied in the 2025, 2026, and 2027 accounting periods.

Pursuant to the relevant provisions of the Law, the following arrangements have been made:

• Taxpayers for whom a special accounting period has been determined shall take into account the fourth provisional tax period of the accounting period commencing within the 2025 calendar year.
• No balance sheet shall be attached to the provisional income and corporate tax returns to be submitted for the fourth provisional tax period, for which it has been deemed appropriate not to apply inflation adjustment.
• Since taxpayers engaged in the purchase, sale, and processing of gold and silver are required to apply inflation adjustment at the end of each provisional tax period, they shall continue to apply inflation adjustment, including for the fourth provisional tax period of the 2025 accounting period.

The provisions of the Law shall enter into force as of the date of its publication.
