On July 24, 2026, the Montenegro Tax Administration published an official determination regarding the statutory interest rate applicable to late tax payments for the final half of 2026. The decision, formalized through an official decree, establishes the interest rate for delayed fulfillment of tax obligations spanning the period from July 18, 2026, to December 31, 2026. The rate, calculated in accordance with the Law on Tax Administration and the General Tax Procedure Law, is set at a fixed annual percentage applied to the outstanding principal amount of any tax liability not settled by its statutory due date. The determination aims to provide taxpayers with clear guidance on the cost of deferred payment, thereby encouraging timely compliance and reducing the administrative burden associated with disputed payment schedules. The interest rate applies uniformly across all categories of domestic taxes, including value-added tax, corporate profit tax, personal income tax, and excise duties, and is indexed to the monetary policy framework established by the Central Bank of Montenegro, which adopts the euro as its official currency. For taxpayers who settle their obligations after the due date but before the end of the calendar year, the accrued interest will be calculated on a pro-rata basis according to the number of days delayed. The Administration has published the full text of the decree in the Official Gazette and on its digital portal, accompanied by illustrative examples of interest calculations for common taxpayer scenarios. This measure is part of a broader set of fiscal policy tools designed to improve tax cash flow, reduce the duration of outstanding receivables, and reinforce a culture of punctual tax compliance among individual and corporate taxpayers alike. Failure to account for the interest obligation in financial planning may result in unexpected tax liabilities at the time of annual reconciliation or audit.
