Taxes and Customs Duties as Instruments for Extracting Oil Rent into the State Budget: The Case of Russia

For countries focused on the extraction and processing of natural resources, including Russia, a crucial task is to ensure the rational extraction and distribution of natural rent. The tax model applied to natural rent should facilitate its optimal allocation to the budget without undermining the motivation of resource users to invest. This study seeks to gauge the extent of oil rent extraction into the Russian budget and suggest strategies to enhance the efficacy of redistributing oil rent to the state budget. Our hypothesis proposes that export customs duties, compared to the mineral extraction tax, prove more effective in achieving the desired redistribution from resource users to the budget. To assess the extent of oil rent extraction, we devised a methodology based on calculating the oil rent generated in Russia. This method involves measuring the difference between the income generated by the oil industry and the total expenses incurred by oil sector companies. Our analysis reveals that, from 2005 to 2022, up to 87% of the oil rent generated in Russia was extracted through rent payments to the state budget. However, in recent years, the degree of oil rent extraction has decreased to 56%. This decline can be attributed to the tax maneuver initiated in Russia since 2015, entailing a reduction and eventual elimination of export customs duties, coupled with an increase in the mineral extraction tax rate. Our results indicate a diminishing effectiveness of rent-based taxation in Russia due to the reduced fiscal significance of rent payments. Furthermore, their regulatory function, designed to incentivize taxpayers for investment contributions, has weakened. These findings offer valuable insights for shaping fiscal policies and lay the groundwork for further research in this domain.
