Late Payment Interest and Deferral Interest Rates Reduced

Late Payment Interest and Deferral Interest Rates Reduced: New Rates Take Effect on November 13, 2025

Changes have been made to the late payment interest and deferral interest rates applied to public receivables. The monthly late payment interest rate of 4.5% applied under Article 51 of Law No. 6183 on the Procedure for Collection of Public Receivables has been set at 3.7% per month, equivalent to 44.4% per annum, effective from November 13, 2025, by Presidential Decree No. 10556 published in the Official Gazette.

The deferral interest rate has also been reduced through Collection General Communique Serial No. 9, published in the same Official Gazette. Accordingly, the deferral interest rate of 48% per annum, equivalent to 4% per month, has been reduced to 39% per annum, equivalent to 3.25% per month.

The new deferral interest rate will apply to public receivables deferred based on applications submitted as of November 13, 2025. For this reason, it is particularly important for taxpayers planning to submit a deferral application to take the application date into account when proceeding.

With this update, a downward revision has been made to both the late payment interest and the deferral interest rates. The new rates become a directly impactful factor in cost planning particularly for individuals and businesses considering the deferral option before restructuring their public debts.
