"The scheduled expiration of a number of energy tax incentives means energy tax policy will likely be considered by the 113th Congress. Under current law, for example, renewable energy projects that begin construction after the end of 2013 will not qualify for the renewable energy production tax credit (PTC). A number of other energy tax incentives, including provisions to support building energy efficiency and renewable fuels, are also scheduled to expire at the end of 2013. In the past, expired and expiring energy tax provisions have been extended as part of 'tax extender' legislation. Energy tax policy may also be considered as part of comprehensive tax reform legislation in the 113th Congress. A base-broadening approach to tax reform might consider the elimination of various energy tax expenditures in conjunction with a reduction in overall tax rates. Alternative revenue sources, such as a carbon tax, may also be evaluated as part of the tax reform process. The President's FY2014 budget proposes a number of changes to energy tax policy. The Obama Administration proposes to repeal a number of existing tax incentives for fossil fuels, while providing new or expanded incentives for alternative and advanced technology vehicles, renewable electricity, energy efficiency, and advanced energy manufacturing."
