U.S. senators push to raise gas tax to shore up Trust Fund

Proposal would increase the federal gasoline and diesel taxes by six cents in each of the next two years for a total of 12 cents. This would provide enough funding to offset current MAP-21 spending levels over the next 10 years.

Two U.S. senators this week unveiled a proposal to raise the gas tax to shore up up the Highway Trust Fund, which funds improvements to roads, bridges and transit systems.

U.S. Senator Chris Murphy (D-Conn.) and U.S. Senator Bob Corker (R-Tenn.) bipartisan proposal to make changes to the federal motor fuels tax,  would create a long-term, stable funding mechanism for the Highway Trust Fund and enact tax relief for American families and businesses.

“For too long, Congress has shied away from taking serious action to update our country’s aging infrastructure,” said Senator Murphy. “We’re currently facing a transportation crisis that will only get worse if we don’t take bold action to fund the Highway Trust Fund.”

The federal Highway Trust Fund provides more than half of the country’s spending on transportation projects and will begin to run dry in July, likely halting the construction of any new transportation projects without action from Congress. This will create a $50 billion hole in states’ 2015 transportation budgets and a $160 billion hole in state budgets over the next decade if left unaddressed.

The federal gas and diesel taxes, which are used to fund this account, have not been updated in over 20 years -- despite the desperate need for road and bridge improvements. As a result, the purchasing power of the gas tax is approximately 63% of what it was in 1993, and continues to decline. A change to the federal gas tax would not only strengthen purchasing power, it would also create thousands of new jobs and allow states to invest in long-term economic development projects.

The senators’ proposal would increase the federal gasoline and diesel taxes by six cents in each of the next two years for a total of 12 cents. This would provide enough funding to offset current MAP-21 spending levels over the next 10 years and replace all of the buying power the federal gas tax has lost since it was last raised in 1993.

The plan would index the gas tax to inflation, using the Consumer Price Index (CPI), to ensure that it remains viable into the future.

To offset the revenue raised from increasing the gas tax to pay for roads and transportation projects, Murphy and Corker propose providing net tax relief for American families and businesses. Examples of tax relief could include: permanently extending some of the tax provisions in the “tax extenders” bill that already have broad, bipartisan support, creating potentially billions of dollars in permanent tax relief for American families and businesses over the next 10 years alone; or another bipartisan proposal to reduce taxes by at least the amount of revenue raised from the gas tax over the next decade.

Historically, this proposal has received bipartisan support. Presidents Ronald Reagan, Bill Clinton, and George H.W. Bush all raised the gas tax in order to fund the Highway Trust Fund and make infrastructure improvements.
