ERISA also approved the use of individual retirement accounts (IRAs) to encourage taxdeferred retirement savings by individuals. The Economic Recovery Tax Act of 1981 (ERTA) provided the largest tax cut up to that time, reducing the maximum individual rate from 70 percent to 50 percent (Pub. L. No. 9734, Aug. 13, 1981, 95 Stat. 172). The most sweeping tax changes since world war ii were enacted in the Tax Reform Act of 1986. This bill was signed into law by President ronald reagan and was designed to equalize the tax treatment of various assets, eliminate tax shelters, and lower marginal rates. Conservatives wanted the act to provide a single, low tax rate that could be applied to everyone. Although this single, flat rate was not included in the final bill, tax rates were reduced to 15 percent on the first $17,850 of ine for singles and $29,750 for married couples, and set at 28 to 33 percent on remaining ine. Many deductions were repealed, such as a deduction available to twoine married couples that had been used to avoid the marriage penalty (a greater tax liability incurred when two persons filed their ine tax return as a married couple rather than as individuals). Although the personal exemption exclusion was increased, an exemption for elderly and blind persons who itemize deductions was repealed. In addition, a special capital gains rate was repealed, as was an investment tax credit that had been introduced in 1962 by President john f. kennedy. The Omnibus Budget Reconciliation Act of 1993, the first budget and tax act enacted during the Clinton administration, was vigorously debated, and passed with only the minimum number of necessary votes. This law provided for ine tax rates of 15, 28, 31, 36, and percent on varying levels of ine and for the taxation of social security ine if the taxpayer receives other ine over a certain level. In 2021 Congress enacted a major ine tax cut at the urging of President gee w. bush. Over the course of 11 years the law reduces marginal ine tax rates across all levels of ine. The 36 percent rate will be lowered to 33 percent, the 31 percent rate to 28 percent, the 28 percent rate to 25 percent. In addition, a new bottom 10 percent rate was created. Since the early 1980s, a flatrate tax system rather than the graduated bracketed method has been proposed. (The graduated bracketed method is the one that has been used since graduated taxes were introduced: the percentage of tax differs based on the amount of taxable ine.) The flatrate system would impose one rate, such as 20 percent, on all ine and would eliminate special deductions, credits, and exclusions. Des
