The state of Illinois is revisiting the concept of a vehicle miles traveled (VMT) tax, an idea that initially surfaced in 2019 but failed to gain traction. Rather of dismissing it outright, a closer examination reveals that a VMT tax might be the solution needed to accurately reflect the costs associated with road usage, not just in Illinois, but across the entire nation.

Illinois currently has the second-highest gas tax in the United States, surpassed only by California. As 2019, this tax has been adjusted upwards annually. This has resulted in approximately $2.8 billion in annual revenue. However, like any tax tied to fuel consumption, its value diminishes over time.

With the rise of fuel-efficient vehicles and the increasing adoption of electric vehicles (EVs), the traditional gas tax is becoming less effective. This necessitates an increase in the tax rate to compensate for the overall decrease in gasoline consumption. While EVs reduce fossil fuel emissions, they don’t necessarily reduce road damage. In fact, heavier EVs may cause more damage to roads per mile driven. Although EV owners bypass gas stations, they still contribute to road wear and tear.

This is where a VMT tax becomes appealing. Rather of taxing fuel, it taxes miles driven, linking road funding directly to the cause of the damage: driving.This transforms the fuel tax into a user fee, similar to a toll, but applicable to all roads.

To optimize this approach, illinois shoudl consider a tiered structure based on vehicle weight to better align taxation with the actual impact on pavement.A heavier vehicle, like a Rivian R1T, will naturally cause more wear than a lighter vehicle like a Chevrolet Bolt.

Proposed legislation, SB1938, allows for variable pricing based on time of day and road type, potentially enabling congestion pricing and better infrastructure load balancing.While not mandated, the state could also tier the fee by vehicle weight, further refining the tax policy to match the actual impact.

Critics argue that a VMT tax could lead to surveillance. The proposal’s pilot program considers transponders and odometer photography,but it requires minimal data collection,prohibits personal details gathering,and offers non-GPS alternatives. It resembles a simple step tracker more than an intrusive monitoring system.

The pilot program is temporary and subject to legislative review, requiring a full report to the General Assembly within 18 months, analyzing revenue, logistics, equity impacts, enforcement, data security, and fraud potential.

illinois is proactively addressing infrastructure funding challenges, having already maximized its gas tax regime. Despite doubling the rate and tying it to inflation, the state still projects important infrastructure revenue shortfalls, indicating an unsustainable system and impending fiscal challenges.

A VMT offers a user fee that adjusts with road usage, independent of oil prices or efficiency improvements, making it potentially more equitable, resilient, and future-proof.

rather of opposing it, Illinoisans should consider making a VMT work, viewing it as an alternative to an ever-increasing gas tax.If successful, Illinois could set a national precedent, as many states face similar challenges with eroding gas tax revenues and crumbling infrastructure.

A well-designed VMT system, tested regionally and scalable nationally, could be a significant step toward future-proofing road funding.
