From 1 April to 30 June 2026, the government has reduced excise and excise-equivalent customs duty rates on petrol and diesel by 60.9% in total – first by 50%, then by a further 10.9%. This means fuel tax credit rates have also been reduced.
To help your business get it right and claim correctly, you can use our fuel tax credit calculator which we've updated with the new rates for this period.
If your business uses petrol and diesel for any business activities other than for travelling on public roads, you'll receive a lower fuel tax credit because the fuel excise duty has been reduced. You'll claim 20.6 cents per litre.
If your business operates heavy vehicles (with a GVM greater than 4.5 tonnes) for travelling on public roads, you'll see a small increase in the fuel tax credit rate for 3 months. This is because the road user charge, which normally reduces your credit, has been temporarily set to zero during this period. This means you'll claim 20.6 cents per litre for petrol and diesel, instead of 20.2 cents per litre.
Fuel tax credit rates are based on the date you acquired the fuel. Different rates apply before 1 April 2026 and from 1 April to 30 June 2026.
