Turkey cut interest on late tax payments and deferred taxes, effective 13 November 2025.
Turkey’s Revenue Administration announced on 13 November 2025 that it had reduced both the monthly interest on late tax payments and the annual interest on deferred taxes.
Under Presidential Decision No. 10556, the monthly interest rate for late tax payments is cut from 4.5% to 3.7%. The decision took effect immediately upon publication in the Official Gazette.
Previously, the rate had been increased from 3.5% to 4.5% in May 2024.
Separately, General Communiqué Series C No. 9 lowered the annual interest rate on deferred tax payments from 48% to 39%. This rate applies when a taxpayer requests a deferral, and it was also raised in May 2024 from 36% to 48%.
The changes aim to encourage timely tax compliance while easing the financial burden on taxpayers.
The new rates took effect yesterday, 13 November 2025.
