The ability to impose a gas tax came in 2019 when Illinois Gov. J.B. Pritzker and state lawmakers doubled the statewide fuel tax. The new law also granted certain counties the power to increase or start a local gas tax “not less than 4 cents per gallon and not more than 8 cents per gallon.” Will County was the first to add a 4-cent tax under the new law, and was followed by DuPage County doubling from 4 to 8 cents in November and the city of Chicago going from 5 to 8 cents on Jan. 1.
The reasoning from the politicians is that they need more tax money to steal or waste.
