Montenegro’s 2026 budget plan: €3.79 billion spending focus, tighter enforcement and OECD-style minimum tax

Montenegro’s 2026 fiscal plan is built around a familiar trade-off: financing growth while protecting the fiscal discipline the country has worked to maintain. The budget for the year is set at about €3.79 billion, supported by slightly higher revenues and a modest increase in borrowing, according to the government’s blueprint.

Spending priorities remain wage- and transfer-heavy

Even with modest growth figures in view, the spending envelope remains heavily weighted toward wages, pensions and social transfers. Together, these items make up the bulk of public expenditure—an allocation that matters for investors because it shapes how much room the state has for discretionary spending changes if economic conditions weaken.

Low headline corporate rates, but tougher collection

Corporate income tax continues to sit within a competitive 9–15% rate band, described as one of the lowest in Europe. The government’s approach keeps the headline regime business-friendly, but the more consequential change for 2026 is expected to come from enforcement rather than statutory rate adjustments.

Authorities have stepped up scrutiny of small businesses, self-employment and home-based economic activity. The stated goal is to raise the effective tax take without increasing statutory rates—while also moving closer to EU standards on transparency and base protection.

Excise duties on tobacco: revenue support versus household pressure

The fiscal picture also includes planned tightening of excise duties on tobacco. Montenegro’s current rate is already at the lower end of what the European Commission tolerates. Officials argue that even a modest increase can help meet revenue targets without severely harming domestic producers, though it adds fuel to a broader debate about how far indirect taxes can be used before households feel the impact.

OECD “two-pillar” reforms extend minimum taxation from 2026

Beyond domestic enforcement and excise policy, Montenegro is implementing parts of OECD-backed “two-pillar” tax reforms. From 1 January 2026, a domestic minimum top-up tax (DMTT) will apply a 15% effective minimum rate to large groups.

The measure is intended to prevent large multinational and major domestic firms from benefiting from substantially lower effective rates simply by locating profits elsewhere. For investors, it signals that Montenegro is aligning more closely with global tax-transparency norms while still maintaining its low-rate positioning—an important consideration for assessing long-term after-tax returns.

Taken together, Montenegro’s 2026 plan combines stable headline corporate taxation with stronger compliance efforts, targeted excise tightening and an OECD-style minimum tax framework—an approach designed to bolster revenues while keeping growth financing within a disciplined budget structure.
