【正文】 the first tax law passed during the Great Depression (Revenue Acts, June 6, 1932, ch. 209, 47 Stat. 169). It increased the individual maximum rate from 25 to 63 percent, and reduced personal exemptions from $1,500 to $1,000 for single persons, and from $3,500 to $2,500 for married couples. The national industrial recovery act of 1933 (NIRA), part of President franklin d. roosevelt39。s new deal, imposed a five percent excise tax on dividend receipts, imposed a capital stock tax and an excess profits tax, and suspended all deductions for losses (June 16, 1933, ch. 90, 48 Stat. 195). The repeal in 1933 of the eighteenth amendment, which had prohibited the manufacture and sale of alcohol, brought in an estimated $90 million in new liquor taxes in 1934. The social security act of 1935 provided for a wage tax, half to be paid by the employee and half by the employer, to establish a federal retirement fund (Old Age Pension Act, Aug. 14, 1935, ch. 531, 49 Stat. 620). The Wealth Tax Act, also known as the Revenue Act of 1935, increased the maximum tax rate to 79 percent, the Revenue Acts of 1940 and 1941 increased it to 81 percent, the Revenue Act of 1942 raised it to 88 percent, and the Individual Ine Tax Act of 1944 raised the individual maximum rate to 94 percent. The postWorld War II Revenue Act of 1945 reduced the individual maximum tax from 94 percent to 91 percent. The Revenue Act of 1950, during the korean war, reduced it to percent, but it was raised the next year to 92 percent (Revenue Act of 1950, Sept. 23, 1950, ch. 994, Stat. 906). It remained at this level until 1964, when it was reduced to 70 percent. The Revenue Act of 1954 revised the Internal Revenue Code of 1939, making major changes that were beneficial to the taxpayer, including providing for child care deductions (later changed to credits), an increase in the charitable contribution limit, a tax credit against taxable retirement ine, employee deductions for business expenses, and liberalized depreciation deductions. From 1954 to 1962, the Internal Revenue Code was amended by 183 separate acts. In 1974 the employee retirement ine security act (ERISA) created protections for employees whose employers promised specified pensions or other retirement contributions (Pub. L. No. 93406, Sept. 2, 1974, 88 Stat. 829). ERISA required that to be tax deductible, the employer39。s plan contribution must meet certain minimum standards as to employee participation and vesting and employer funding. 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 2020 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. Despite firm support by some, the flatrate tax has not been adopted in the United States. Regardless of the changes made by legislators since 1913, the basic formula for puting the amount of tax owed has remained basically the same. To determine the amount of ine tax owed, certain deductions are taken from an individual39。s gross ine to arrive at an adjusted gross ine, from which additional deductions are taken to arrive at the taxable ine. Once the amount of taxable ine has been determined, tax rate charts determine the exact amount of tax owed. If the amount of tax owed is less than the amount already paid through tax prepayment or the withholding of taxes from paychecks, the taxpayer is entit
