Illinois’ gas tax goes up on July 1st. Here’s by how much:

SPRINGFIELD, Ill. (WTVO) — Illinois drivers: brace yourselves. The annual gas tax increase is about to kick in on July 1st, 2025.

The automatic Motor Fuel Tax increases to account for inflation.

Currently, Illinois residents pay the second-highest gas tax in the country, behind California.

The gas tax is now .45 cents per gallon, but on July 1st it will go up to .47 cents per gallon.

The average car holds between 12 and 16 gallons of gas, meaning drivers should expect to spend between .24 and .32 cents extra at the pump. The Motor Fuel Tax will account for a range of $5.64 and $7.52 in taxes per full tank of gas, on average.

The tax on diesel fuel rises from .52 cents to .54 cents per gallon.

A new proposal in Springfield would change how Illinois funds its roads by charging drivers by the mile instead of a gas tax.

The proposal, filed by Sen. Ram Villivalam (D-Chicago) and Sen. Christopher Belt (D-East St. Louis), calls for starting a pilot program to study the effectiveness of charging drivers by the mile, something the state is considering due to the prevalence of more fuel-efficient and electric vehicles on Illinois roadways.

Since fuel-efficient cars use less gasoline, fewer tax dollars will be available for road infrastructure.

Electric vehicle owners currently pay a $100 premium on their annual license plate sticker renewal to offset losses to the Illinois Motor Fuel Tax.

Oregon and Utah have already implemented similar programs, and five other states, including Pennsylvania and California, are considering it.
