Key Legislation: Petroleum Resource Rent Tax Assessment Act 1987
PRRT was substantially altered in 1990 to allow undeducted exploration expenditure incurred after that date to be transferred to other projects. Simultaneously, the carry-forward rate of undeducted general projects expenditures was significantly reduced from the long-term bond rate plus 15 percentage points to the LTBR plus 5 percentage points.
The wider deductibility provisions were limited by applying several restrictions and conditions on this area of the legislation. Changes made in 1992 and 1993 clarified the treatment of transferable expenditure as well as lodgement provisions. A technical amendment passed in 2000 addressed an uncertainty associated with the treatment of expenditures when a party "walks-away" from a continuing joint venture. In 2001, a number of changes were made to the operation of the five-year GDP factor rule and the introduction of a gas transfer pricing mechanism.
The regime was further modified and extended in 2003 to clarify the treatment of income and expenditures in which a project is used to toll or process external or third-party petroleum. In 2004, the government introduced a 150% incentive to assist exploration in nominated frontier areas. This was incentive lapsed in 2010.
From 1 July 2006, several technical enhancements were introduced to improve the regime's operation and efficiency. A transfer notice requirement was introduced for vendors disposing of an interest in a permit; a deduction for transferable exploration expenditure was now required when calculating quarterly instalments; and taxpayers could now use self-assessment provisions.
PRRT receipts are retained wholly by the Federal Government. Collections for the period 1989/90 to 2010/11 were as follows:
