Agrinews » The “Build America Fund” would increase gas taxes for gasoline and diesel by 20 cents per gallon. The plan would phase in the tax increases, starting with a 5-cent increase and then moving to the full 20-cent increase by 2021 and continuing at 20 cents until 2027. The tax would be collected on motor fuel at the wholesale terminal rack, before the fuels reach the retail level. The American Trucking Association is promoting the tax increase as an alternative to increased tolling.
