HB1637 amends the Illinois Motor Fuel Tax Law to pause the annual inflation-based increase in the motor fuel tax rate. Under current law, the motor fuel tax is adjusted upward each July 1 based on changes in the Consumer Price Index (CPI). This bill would prohibit that CPI-based increase from taking effect from July 1, 2025 through July 1, 2027, effectively freezing the inflation adjustment for two years. The bill is effective immediately.
The measure does not repeal the motor fuel tax or change the base tax structure; it only suspends the automatic CPI indexing mechanism for the specified period. As a result, motorists, fuel retailers, and other fuel purchasers would avoid the scheduled inflation-driven tax increase during that window, while the Department of Revenue would continue administering the tax under existing law once the suspension ends. The bill specifically amends Section 2 of the Motor Fuel Tax Law, which governs gasoline and related fuel taxes, including diesel, liquefied natural gas, propane, and certain other fuel categories covered by the statute.
The general sentiment suggested by the bill title and structure is tax-relief oriented, with the proposal framed as a temporary pause on a scheduled tax increase rather than a broader overhaul of transportation funding. Because there are no committee transcripts or recorded votes provided, there is no documented public debate in the supplied materials. However, the bill’s purpose indicates an intent to reduce near-term fuel costs for consumers and businesses affected by fuel prices.
The main point of contention likely concerns the tradeoff between short-term relief at the pump and reduced growth in state motor fuel tax revenue that supports transportation-related funding. Supporters would likely emphasize affordability and predictability for drivers, while opponents may argue that suspending CPI indexing weakens the state’s ability to keep pace with inflation and maintain infrastructure funding. No specific legislators, agencies, or stakeholder groups are identified in the provided record as taking a formal position.
Impact
HB1637 would temporarily amend Section 2 of the Motor Fuel Tax Law by suspending the statute’s automatic CPI-based annual rate increase for motor fuel taxes from July 1, 2025 through July 1, 2027. This would delay inflation indexing of the per-gallon tax rate without changing the underlying tax itself, affecting gasoline and other motor fuels taxed under the law, including diesel, liquefied natural gas, and propane. The bill would reduce expected motor fuel tax revenue during the suspension period and would alter the timing of future rate adjustments administered by the Department of Revenue.
Sentiment
The bill appears to have a generally pro-consumer, tax-relief sentiment, as reflected by its title and its narrow focus on stopping an automatic tax increase rather than expanding taxation. In the absence of committee testimony or votes, there is no recorded opposition or support in the supplied materials, but the policy direction suggests an appeal to motorists and fuel users concerned about rising costs. The measure is likely to be viewed favorably by those seeking to limit fuel tax growth and more cautiously by those focused on transportation funding stability.
Contention
The central contention is the balance between consumer relief and state revenue. Supporters of the bill would likely argue that freezing the CPI adjustment for two years prevents an automatic tax hike during a period of higher fuel and living costs. Opponents would likely contend that the CPI adjustment is intended to preserve the real value of the motor fuel tax over time and that suspending it could reduce resources for roads, bridges, and transportation programs.
