On March 19, 2025, the Illinois House of Representatives introduced House Bill 3810, a legislative proposal aimed at promoting the use of sustainable aviation fuel (SAF) while providing tax incentives for retailers involved in its sale. The bill seeks to address environmental concerns associated with traditional aviation fuels by encouraging the adoption of cleaner alternatives.

The primary provision of House Bill 3810 allows retailers to accept a Sustainable Aviation Fuel Purchase Credit certification from air common carrier purchasers. This credit can be applied to satisfy Use Tax on aviation fuel sales, effective from July 1, 2023, through December 31, 2032. Retailers can utilize this certification to offset their Retailers' Occupation Tax liability, capped at 6.25% of the receipts from qualifying sales. To qualify for the credit, retailers must maintain documentation confirming that the aviation fuel sold meets the definition of sustainable aviation fuel as outlined in the bill.

The introduction of this bill has sparked discussions among lawmakers and stakeholders regarding its potential impact on the aviation industry and environmental policy. Proponents argue that the bill represents a significant step towards reducing carbon emissions in air travel, aligning with broader climate goals. However, some critics express concerns about the feasibility of implementing the necessary documentation and certification processes, which could pose challenges for retailers.

Economic implications of House Bill 3810 are noteworthy, as it aims to stimulate the market for sustainable aviation fuel, potentially leading to job creation in the green energy sector. Additionally, the bill could enhance Illinois' position as a leader in sustainable practices within the aviation industry.

As the legislative process unfolds, experts anticipate further debates and possible amendments to refine the bill's provisions. The outcome of House Bill 3810 could set a precedent for similar initiatives in other states, influencing the future of aviation fuel standards and environmental regulations nationwide. The Illinois House will continue to review the bill, with discussions expected to focus on balancing environmental objectives with the operational realities faced by retailers and air carriers.
