Montenegro’s repeated cuts to fuel excise duties have reduced mineral-oil tax revenue by €8.4 million in the first eight months of 2026, quantifying the fiscal cost of government efforts to soften the impact of higher pump prices.
Finance Ministry data show excise revenue from mineral oils and derivatives totalled €125.8 million in January-August, down 6.3% from a year earlier and around €10 million below plan.
The government currently applies a 40% reduction in diesel excise, lowering the retail price by approximately €0.21 per litre compared with the full tax rate.
Diesel nevertheless remains around €1.95 per litre, showing that tax intervention has moderated rather than reversed the increase in underlying fuel costs.
The revenue decline is significant because fuel taxes are one of Montenegro’s more stable consumption-based revenue sources.
The budget impact has so far been cushioned by stronger receipts elsewhere.
Total excise revenue reached €279.6 million through August, up around €19.1 million year on year.
Tobacco excise revenue alone increased by about €23.8 million, more than offsetting the fuel-related shortfall.
That gives the government room to continue temporary fuel support without creating an immediate hole in overall excise collection.
But the structure matters.
Higher tobacco revenue cannot be assumed indefinitely, while repeated fuel-tax reductions can become expensive if international energy prices remain elevated.
The government has used excise cuts because they reduce pump prices immediately and are simple to administer.
For businesses, the effect is material.
Transport, construction, retail distribution and tourism logistics are heavily exposed to diesel.
Every €0.10 per litre increase can accumulate into substantial operating costs for companies running large vehicle fleets or construction machinery.
Fuel also feeds indirectly into the price of food and other goods.
Reducing excise therefore acts as both household relief and a wider anti-inflation measure.
The cost is foregone tax revenue.
A €0.21-per-litre reduction applied across large national fuel volumes can quickly produce millions of euros in lost receipts.
The government must therefore decide how long temporary relief should remain in place.
Montenegro imports nearly all of its petroleum products, leaving domestic prices exposed to international crude prices, refining margins, regional supply and transport costs.
Excise is one of the few components the government can change directly.
Strategic oil reserves can improve supply security but do not provide the same immediate retail-price mechanism.
The country is building reserves intended eventually to cover 90 days of supply.
That will reduce vulnerability to physical shortages but will not eliminate international price exposure.
The fiscal trade-off is becoming clearer.
Montenegro collected less from fuel but more from tobacco and other excisable products.
Total revenue therefore remains strong even as one category underperforms.
The wider tax system is also benefiting from rising collections, with gross Tax Administration receipts approaching €1.2 billion in the first eight months.
That strengthens the government’s ability to absorb the fuel intervention in 2026.
The position may become more difficult in 2027.
Montenegro is preparing a major wage and tax overhaul, large infrastructure spending and further EU-related investment.
Permanent revenue losses become harder to accommodate when expenditure commitments rise.
The key question is therefore whether the fuel-excise cuts remain temporary.
If international prices ease, restoring the full rate would recover much of the lost fiscal capacity.
If high prices persist, political pressure to keep relief in place will remain.
For now, stronger tobacco receipts have hidden much of the headline impact.
The fuel intervention has already cost €8.4 million in year-on-year revenue.
The budget can absorb that.
The risk is what happens if temporary relief becomes the new normal.
