The Treasury has made the Excise Tariff (Fuel Duty Temporary Reduction) Determination 2026 (F2026L00411), effective 1 April 2026, constituting Part 2 of a temporary fuel duty reduction scheme authorized under the Excise Tariff Act 1921. Section 5 provides for the determination of a lower percentage for fuel duty, continuing measures established in Part 1 of the instrument. This final legislative instrument applies to all entities engaged in fuel importation, production, and retail.

Fuel industry participants should immediately review current excise duty calculations and update point-of-sale systems and excise reporting processes to reflect the reduced duty rates. Businesses holding fuel stocks subject to excise should verify inventory valuations and input tax credit entitlements under the new determination. The reduction takes effect on 1 April 2026, and entities must ensure compliance with amended reporting obligations from this date.
