To amend the Internal Revenue Code of 1986 to extend authorities relating to the Highway Trust Fund, to provide revenues for highway programs, and for other purposes.

Summary: American Energy and Infrastructure Jobs Financing Act of 2012 - Amends the Internal Revenue Code to: (1) extend through September 30, 2016, the expenditure authority for the Highway Trust Fund; and (2) extend through September 30, 2018, current excise tax rates on motor fuels (i.e., gasoline, diesel fuel and kerosene, and special motor fuels), excise taxes on heavy highway vehicles and highway tires, and the use tax on heavy vehicles.

Appropriates to the Highway Trust Fund amounts equivalent to the net increase in revenues from onshore and offshore domestic energy leasing and production resulting from the Alaskan Energy for American Jobs Act, the PIONEERS Act, and the Energy Security and Transportation Jobs Act.
