In the 2011-12 Budget released on 10 May 2011, the Government announced that it would amend the Taxation of Financial Arrangements tax hedging rules to ensure that the rules operate as intended, and to provide further certainty and reduce compliance costs for affected taxpayers. A Regulation Impact Statement was required to inform the decision as this measure would have a regulatory impact on business compliance costs but was not prepared. Consequently, the Office of Best Practice Regulation has assessed the proposal as being non-compliant with the Australian Government’s best practice regulation requirements. A post-implementation review for this measure will be required within one to two years of its implementation.
