Montenegro has officially adopted a global minimum tax framework, marking a pivotal change in its approach to corporate taxation for large multinational groups. The new regulation, established through the Law on the Global Minimum Corporate Income Tax, was passed by the Montenegrin parliament in late February and published on March 10, 2026. This law will take effect on January 1, 2026, aligning Montenegro with the OECD/G20 Pillar Two initiative aimed at curbing profit shifting and ensuring that major corporations pay a minimum level of tax in their operating jurisdictions.
This legislative change introduces a minimum effective corporate tax rate of 15%, preventing large business groups from utilizing low-tax jurisdictions or complex internal structures to lower their tax liabilities. The law specifically targets groups with consolidated annual revenues exceeding €750 million in at least two of the previous four fiscal years, thereby focusing on multinational corporations and significant domestic entities rather than smaller businesses.
The introduction of the global minimum tax is designed to enhance Montenegro’s fiscal framework by allowing the government to collect any shortfall between a corporation’s effective tax rate and the mandated 15%. This mechanism asserts Montenegro’s right to capture additional tax revenue domestically instead of relinquishing it to other jurisdictions under global anti-base erosion rules.
Montenegro’s existing corporate income tax system features progressive rates ranging from 9% to 15%, which remains unchanged for most companies. The new global minimum tax creates a distinct layer for larger entities, ensuring that their effective tax rates are scrutinized more rigorously. As part of this reform, companies must submit detailed electronic reports regarding their top-up tax alongside their regular tax returns within 18 months post-fiscal year-end.
This shift represents a significant evolution in Montenegro’s corporate tax oversight, moving from a low-rate model towards one characterized by greater transparency and compliance obligations. For foreign investors and corporate advisors, the implications are profound; effective tax rates will now be more critical than statutory rates, as any deductions or accounting practices that lower the effective rate below 15% may be countered by the top-up tax.
The law also imposes penalties for non-compliance, with fines ranging from €3,000 to €40,000 for companies failing to meet reporting requirements. Individuals responsible for compliance may face penalties between €500 and €4,000. While these amounts may seem modest relative to the scale of affected corporations, they underscore the seriousness with which Montenegro is implementing this regulatory framework.
<pCertain entities are exempt from this new law, including state bodies and non-profit organizations that meet specified criteria. This aligns with global standards aimed at profit-making businesses rather than public-sector entities.
<pOverall, Montenegro’s adoption of the 15% global minimum tax is part of a broader strategy to align its corporate tax system with European and international standards. While immediate revenue gains may be limited due to the narrow scope of affected groups, the strategic benefits include enhanced credibility with institutional investors and improved compliance with OECD guidelines. This reform signals Montenegro’s commitment to maintaining fiscal competitiveness while adhering to evolving international tax norms.
As a result of these changes, large corporations operating in Montenegro will need to reevaluate their governance structures concerning tax compliance. Effective modeling of tax rates and comprehensive documentation will become essential components of their operational frameworks, particularly for those with intricate cross-border transactions or substantial discrepancies between accounting profits and taxable income.
<pIn conclusion, Montenegro's new taxation policy is not merely an increase but rather a structural adjustment aimed at integrating into a globally standardized taxation environment while safeguarding its fiscal interests.
