The purpose of this paper is an assessment of the risk of regional tax systems at different levels of the budget system (consolidated, federal, regional and local), decomposition of this risk by sources (various taxes and tax groups) and the isolation of internal (related to own tax return volatility) and external (related to the correlation of tax returns volatility) risk components. Using the portfolio approach, we measured and decomposed the risk of tax systems of 80 constituent entities of the Russian Federation in 2006–2017. As a result, we found a weak positive relationship between the risk and return of the regional tax systems at all budget levels. By comparing the structure of return and risk of regional tax systems, we identified taxes – risk dampers and taxes – risk enhancers, and estimated the overall level of imbalance in regional tax systems at the studied budget levels. It allowed us to conclude about the effectiveness of diversification of regional tax systems, the advisability of combining different taxes in a single portfolio, or transferring them to another level of the budget system.
