The Neutrality of the Resource Rent Tax

Abstract

Although less distorting than conventional royalties and income tax, the resource rent tax is strictly neutral only if the interest rate at which losses are carried forward relates correctly to the discount rate employed by investors in project evaluation. Thus it is possible in principle to design a resource rent tax that is strictly neutral only if parameters are set independently for each minerals investment. Such attempts to tailor parameters to each investment would make great demands on information and would increase business uncertainty. The paper suggests expedients to reduce the costs of non‐neutrality when resource rent tax is applied with parameters that are of general application and discusses their use in Australia.
