Montenegro has mandated automatic exchange of cross-border tax rulings and transfer pricing agreements with EU authorities, requiring disclosure of 12 mandatory data points for transactions exceeding EUR 1,500,000 from 1 January 2026 onwards, while protecting sensitive commercial information from centralised disclosure.
Montenegro’s government has published Rulebook No. 10/1-1-01-040/26-2637/4 in the Official Gazette on 7 August 2026, clarifying the automatic exchange of information (AEOI) with EU member states and the European Commission (EC) on previous transfer pricing agreements and tax rulings with cross-border implications.
The enactment of the “Rulebook on the closer method of reporting on advance tax rulings with cross-border impact and advance pricing agreements” signifies a pivotal advancement in Montenegro’s integration into the global fiscal transparency framework.
As Montenegro aligns its domestic legislation with international standards, specifically those governing the automatic exchange of information (EOI), this Rulebook serves as a definitive compliance roadmap. It is designed to facilitate a seamless bidirectional exchange of information, ensuring that tax authorities possess the requisite data to combat base erosion and profit shifting (BEPS) while providing a predictable environment for multinational entities operating within the jurisdiction.
Mandatory reporting categories
The tax authority must now report on twelve specific data points when cross-border rulings or pricing agreements are issued, amended, or renewed after 1 January 2026, provided the transaction value exceeds EUR 1,500,000 or the ruling determines tax residency of Montenegro.
The twelve mandatory categories encompass: taxpayer identification and affiliated group membership; detailed business summary describing relevant activities and transactions; formal issuance date; validity commencement date; validity expiration date; specific legal classification of the ruling type; financial transaction value (when specified); transfer pricing criteria or the actual transfer price applied; identification of transfer pricing methods used (such as comparable uncontrolled price, cost plus, resale price, profit split, or transactional net margin method); identification of other jurisdictions potentially affected by the arrangement; identification and state linkage of each person in foreign states connected to the ruling; and whether information originates from the ruling itself or from specific request by another jurisdiction.
The summary content must allow other tax authorities to conduct preliminary risk assessment without revealing trade secrets or breaching public policy restrictions.
Exchange timelines and procedures
Tax authorities must transmit information to EU member states and the European Commission within three months following the end of each half-calendar year in which the ruling or agreement was issued, amended, or renewed. This semi-annual reporting cycle ensures timely dissemination while allowing authorities time to verify documentation accuracy.
Receiving authorities must confirm receipt via electronic means or within seven working days of notification. This confirmation requirement establishes an auditable record of information flow and prevents administrative gaps in the exchange process.
Article 3, paragraph 4, permits tax authorities to request full documentation of cross-border rulings or pricing agreements from EU member states when summarised data proves insufficient for detailed audit purposes.
Data protection and exclusions
Specific restrictions protect sensitive commercial and personal information from centralised disclosure.
The European Commission does not receive taxpayer or group identification (Item 1), business summaries (Item 2), transfer pricing criteria (Item 8), or linked person identification in foreign states (Item 11). This safeguard reserves detailed taxpayer information for national tax authorities conducting direct enforcement.
Additionally, rulings concerning individual physical persons remain excluded from automatic exchange when they address taxation at source for non-resident wages or employment income, directors’ fees, or pension arrangements.
Multilateral coordination framework
The rulebook aligns Montenegro with international transparency standards (Common Reporting Standard and BEPS Action Item 5) while preserving national authority over tax enforcement and audit procedures. It standardises reporting with EU member states without surrendering domestic control.
