For a single taxpayer in 1993, the federal government imposed a statutory marginal income tax rate of 15 percent on each additional (“marginal”) dollar earned by the taxpayer up to an income of $22,100; 28 percent on the marginal income between $22,100 and $53,500 ; and so on for the other statutory rates of 31, 36, and 39.6 percent.
Effective average tax rates, by contrast, represent the actual tax burden of a taxpayer (whether on a single type of tax or on al l taxes combined) divided by that taxpayer’s total income.Share
