Statutory Individual Income Tax Rates and Other Elements of the Tax System: 1988 through 2008
"Statutory individual income tax rates, also referred to as "statutory marginal tax rates," are the rates of tax applicable to the last (marginal) increment of taxable income. Statutory rates play an important role in determining the real marginal tax rates, which affect taxpayers' economic behavior. Developments since enactment of the Tax Reform Act of 1986 (TRA86; P.L. 99-514) are the most relevant to the current state of affairs. Since then, the Omnibus Budget Reconciliation Act of 1990 (OBRA90; P.L. 101-508), the Omnibus Budget Reconciliation Act of 1993 (OBRA93; P.L. 103-66), and the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA; P.L. 107-16) and its extensions all changed the marginal income tax rate structure. Under current law, upon expiration of tax cuts enacted in 2001-2007, the rate structure will revert in 2011 to the one set by OBRA93. The six marginal income tax rates for 2008 are 10%, 15%, 25%, 28%, 33%, and 35%..."
