The Greenbook: General Explanations of the Administration's Revenue Proposals
To accompany the Administration's Budget, Treasury releases the "Greenbook," which provides an explanation of the Administration's revenue proposals.
Tax Expenditures describe revenue losses attributable to provisions of Federal tax laws which allow a special exclusion, exemption, or deduction from gross income or which provide a special credit, a preferential rate of tax, or a deferral of tax liability. These exceptions are often viewed as alternatives to other policy instruments, such as spending or regulatory programs.
