The General Revenue (GR) Fund, also known as the general fund, is the principal funding source for most Oklahoma government operations. Any revenue that is not restricted for a specific purpose flows into the general fund. The Legislature may direct money out of this fund for any legal purpose of the government.
Total General Revenue collections in FY 2021 were $7.008 billion, which was $734.6 million, or 11.7 percent, more than in FY 2020. The biggest contributors to the General Revenue Fund were the individual income tax ($2.886 billion, 41 percent) and sales tax ($2.197 billion, 31 percent). Dozens of smaller taxes and fees made up the rest.
The Legislature can budget up to 95 percent of the estimated General Revenue for the coming year (see Revenue Estimates). For Fiscal Year 2022, 73 percent of the money budgeted by the Legislature comes from General Revenue.
