The recent surge in gasoline prices has reignited political speculation about suspending the federal tax on the fuel, following proposals from high-profile Democrats who propose suspending the 18.3-cent-per-gallon gas tax and 24.3.5-cent diesel tax, which support the nation's Highway Trust Fund. The Bipartisan Policy Center estimates that suspending the tax could reduce retail prices by 9-14% per gallon. This proposal is separate from a proposal by state Republican lawmakers to give Virginians a 90-day reprieve from the state's 32-cent gas tax. However, Congress must approve a federal suspension of the gas tax, and tax holidays could potentially decrease revenue used for maintaining state and nation's highways.
