NASBO staff have been reading through governors’ fiscal 2020 budget recommendations and summarizing some of their key elements through a series of issue briefs. This issue brief focuses on tax and revenue measures. Most of governors’ fiscal 2020 budget recommendations include some form of revenue increase or decrease proposals. The net revenue impacts for the bulk of them are minor. Only five states propose recurring revenue changes exceeding two percent of general revenues. The three most common tax changes advanced in governors’ budget proposals are: excluding retirement income, taxing electronic cigarettes, and raising the gas tax. The state examples provided are meant to be illustrative but not exhaustive.
