Hopes for infrastructure deal with Trump rise if Dems win House
Lawmakers should pursue vehicle mileage tax to save Highway Trust Fund: study
Lawmakers should pursue a vehicle-mileage tax to rescue the struggling Highway Trust Fund, a right-leaning think tank argues in a new study.
The American Action Forum (AAF) makes the case for a mileage-based tax and provides other suggestions for a long-term fix to the ailing fund, which pays for road projects and is headed for another shortfall at the end of 2020.
"A mileage-based tax is a more stable alternative to the gas tax. Immediate implementation of a federal mileage-based tax, however, is unrealistic," the study says.
Some Republican lawmakers have pointed to a vehicle-mileage tax as a means to fund infrastructure projects, but they also note that these programs are not ready for implementation.
Meanwhile, the White House Council of Economic Advisers in a February report touted a vehicle-mileage tax program in Oregon that charges its volunteers 1.7 cents for every mile they travel on the state's public roads. The program then awards its participants with credits for the state's fuel taxes.
The AAF calls for "a combination of new user fees implemented alongside the existing gas tax," but notes that upping the gas fee alone will not provide the Highway Trust Fund with lasting relief or stability.
"If Congress only looks at raising the gas tax, that doesn't create long-term funding for the Highway Trust Fund due to alternative fuel vehicles and autonomous vehicles emerging in the market," AAF data analyst Brianna Fernandez, who authored the study, told The Hill.
Industry leaders have long pushed for an increase to the gas tax, which has not been raised from its current 18.4 cents per gallon in 25 years, eroding the fund's purchasing power over time. The U.S. Chamber of Commerce in January argued for an increase to the levy as a means to pay for rebuilding the nation's crumbling infrastructure.
Lawmakers said President Trump backed a 25-cent increase to the tax during a February meeting at the White House, though the administration did not address the Highway Trust Fund in its infrastructure proposal released earlier this year.
The AAF study also suggests imposing congestion pricing, which is often executed by adjusting toll prices in accordance with demand.
"For the long term, we can't just continue to rely on the gas tax and moving more towards vehicle miles tax and congestion pricing is what's going to create that long-term funding," said Fernandez.
Fernandez said Congress should continue evaluating the vehicle-mileage tax approach to fix the "broken" Highway Trust Fund.
"The Highway Trust Fund can't just be fixed in one pinch. It's going to take him and it's going to take a lot of pilot programs, a lot of research, but this something that's worth exploring," she said.
