Illinois’ Gas Tax Is Going Up–Here’s How Much More It’ll Cost You

Sometimes in news stories about taxes going up for one reason or another, the story will point out how the tax increase will have a tougher affect on one group of people than it will on other groups.

I guess we should be grateful here in Illinois that our scheduled increase in Illinois' motor fuel tax is something that every group is going to feel and have to deal with, not just a small segment of society.

Try to enjoy filling up your vehicle as much as you can over the next month and a half (which, c'mon--when's the last time you really enjoyed pumping gas and then paying for it?) because on July 1st, every visit to the gas pump in Illinois is going to take more money out of your wallet...until next year, when Illinois' gas tax could go even higher.

Illinois' Gas Taxes Are Going Up On July 1st, Even Though We're Already The State With The 2nd Highest Gas Tax In The Nation

California's gas tax currently wears the crown as the highest gas tax in the United States, but here in the state of Illinois, we're doing everything we can to close the gap between first and second places.

When Illinois' new gas tax kicks in on July 1st, we'll go from paying 47 cents per gallon in taxes to 48.3 cents per gallon, as part of a "two-part" fuel tax, according to Patch.com:

The Part A gas tax rates that take effect July 1, 2025, are gasoline and compressed natural gas at 48.3 cents per gallon, and diesel, liquefied natural gas and propane at 55.8 cents per gallon.

When it comes to Part B tax rates that are currently in effect for fiscal 2025, you get:

• Diesel: 19.1 cents per gallon
• Gasoline: 18.6 cents per gallon
• Propane: 17.2 cents per gallon
• Liquefied natural gas: 15.3 cents per gallon
• Compressed natural gas: 12.6 cents per gallon

Illinois drivers, on average, are looking at spending an extra $143 every year with the raising of the gas tax on July 1st.

Here's A Look Back At How Illinois' Gas Taxes Have Skyrocketed Under Governor Pritzker

It all started shortly after the governor was first elected and decided that doubling the gas tax would be the prudent move, taking it from 19 cents per gallon to 38 cents per gallon.

• July 2018: (pre-Pritzker) 19 cents
• July 2019: 38 cents
• July 2020: 38.7 cents
• July 2021: 39.2 cents
• July 2022: 39.2 cents
• January 2023: 42.3 cents
• July 2023: 45.4 cents
• July 2024: 47.0 cents
• July 2025: 48.3 cents

As if these numbers weren't enough, Illinois lawmakers are also kicking around the idea of a vehicle mileage tax because Springfield is saying that the state is not getting enough money for our state's roads.
