Passage History

Commonwealth Places Windfall Tax (Imposition) Bill 1998

Date Introduced: 5 March 1998

House: House of Representatives

Portfolio: Treasury

Commencement: This Bill will be taken to have commenced on 6 October 1997.


The Commonwealth Places Windfall Tax (Imposition) Bill 1998 (the Windfall Tax Imposition Bill) is part of a package of four Commonwealth Bills dealing with the consequences of the High Court's decision in Allders International Pty Limited v Commissioner of State Revenue (Victoria) (Allders).(1) The package of legislation is designed to overcome constitutional obstacles, so that certain State taxes will continue to apply to Commonwealth places located within the States and past State revenues are protected.

The purpose of the Windfall Tax Imposition Bill is to impose a windfall tax of 100%. With its companion law, the Commonwealth Places Windfall Tax (Collection) Bill 1998, the Bill is designed to protect State revenues from claims for refunds in relation to certain taxes applied in Commonwealth places. Claims by various taxpayers to a refund would be expected to flow from the Allders decision on the basis that the taxes were constitutionally invalid. A 100% windfall tax will deter refund claims and protect State revenues.

The purpose of the package of four Bills and the main features of the regime they establish are set out in more detail in the Bills Digest for the Commonwealth Places (Mirror Taxes) Bill 1998.


A detailed 'background' to the package of Bills designed to respond to the High Court decision in Allders International Pty Limited v Commissioner of State Revenue (Victoria) is provided in the Bills Digest for the Commonwealth Places (Mirror Taxes) Bill 1998.

Two Bills have been used to implement the windfall tax presumably due to the provisions of section 55 of the Commonwealth Constitution. Section 55 provides amongst other things that laws imposing taxation can deal only with the imposition of taxation. As a result, the same bill must not contain measures providing for the imposition of a tax and the establishment of machinery necessary for it to be collected.

Main Provisions

Clause 4 imposes the Commonwealth places windfall tax at the rate of 100%.
