Notes:
1. Taxable income excludes zero bracket amount from 1977 through 1986. Rates shown apply only to married persons filing joint returns beginning in 1948. Does not include either the add on minimum tax on preference items (1970-1982) or the alternative minimum tax (1979-present). Also, does not include the effects of the various tax benefit phase-outs (e.g. the personal exemption phase-out). From 1922 through 1986 and from 1991 forward, lower rates applied to long-term capital gains.
 
2. Beginning in 1975, a refundable earned-income credit is allowed for low-income individuals.
 
3. Rates for 2003 are after enactment of the Jobs and Growth Tax Relief Reconciliation Act. Prior to enactment the rates were 10% up to $12,000 and 38.6% on amounts over $311,950.
 
4. The benefit of the first rate bracket is eliminated by an increased rate above certain thresholds. The phase-out range of the benefit of the first rate bracket was as follows: Taxable income between $71,900 and $149,250 in 1988; taxable income between $74,850 and $155,320 in 1989; and taxable income between $78,400 and $162,770 in 1990. The phase-out of the benefit the first rate bracket was repealed for taxable years beginning after December 31, 1990. This added 5 percentage points to the marginal rate for those by the phaseout, producing a 33 percent effective rate.
 
5. After tax credit is 1.25 percent against regular tax.
