Temporary changes in fuel taxes from May 1, 2026

From May 1, 2026, new, temporary reductions in the CO2 tax will take effect for several types of mineral oil and fuel. The changes follow the Storting's decision on reduced fuel taxes and apply in principle until September 1, 2026.

The Government has adopted regulations for the implementation of the remaining tax changes that were not put into effect on April 1. The Norwegian Tax Administration has also published updated rates for the relevant tax areas.

Reservations are made regarding any subsequent clarifications or changes from the authorities. If new clarifications come to light that affect the tax base, the prices may be adjusted accordingly.

What do the changes mean?

Petrol

There is no new tax reduction on petrol from May 1. The road use tax was set to zero from April 1, and the CO2 tax on petrol is unchanged.

Road diesel

For road diesel, the CO2 tax is reduced from 4.42 to 3.09 NOK per litre. This gives a tax reduction of 1.33 NOK per litre excl. VAT, corresponding to 1.66 NOK per litre incl. VAT.

This is the change that most affects regular road transport, commercial transport, and diesel-powered passenger cars.

Construction diesel

For construction diesel, the CO2 tax is reduced from 4.42 to 1.92 NOK per litre. This gives a reduction of 2.50 NOK per litre excl. VAT, corresponding to 3.13 NOK per litre incl. VAT.
