The colonists39。 the explanation of the tax reform act of 1986 was more than thirteen hundred pages long (Pub. L. 99514, Oct. 22, 1986, 100 Stat. 2085). Commerce Clearing House, a publisher of tax information, released a version of the Internal Revenue Code in the early 1990s that was four times thicker than its version in 1953. Changes to the tax laws often reflect the times. The flat tax of 1913 was later replaced with a graduated tax. After the United States entered world war i, the War Revenue Act of 1917 imposed a maximum tax rate for individuals of 67 percent, pared with a rate of 13 percent in 1916. In 1924 Secretary of the Treasury Andrew W. Mellon, speaking to Congress about the high level of taxation, stated, The present system is a failure. It was an emergency measure, adopted under the pressure of war necessity and not to be counted upon as a permanent part of our revenue structure…. The high rates put pressure on taxpayers to reduce their taxable ine, tend to destroy individual initiative and enterprise, and seriously impede the development of productive business…. Ways will always be found to avoid taxes so destructive in their nature, and the only way to save the situation is to put the taxes on a reasonable basis that will permit business to go on and industry to develop. Consequently, the Revenue Act of 1924 reduced the maximum individual tax rate to 43 percent (Revenue Acts, June 2, 1924, ch. 234, 43 Stat. 253). In 1926 the rate was further reduced to 25 percent. The Revenue Act of 1932 was the first tax law passed during the Great Depression (Revenue Acts, June 6, 1932, ch. 209, 47 Stat. 169). It increased the 湖南警察學(xué)院畢業(yè)論文 16 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。Italia, 536 . 238, 122 S. Ct. 2117, 153 L. Ed. 2d 280 (2021), upheld the IRS aggregate method of reporting tip ine. Instead of requiring the IRS to make individual determinations of unreported tips for each employee when calculating FICA tax, the Court held that the IRS could make employers report their gross sales on a monthly statement to help determine tip ine. Employees also must report their tip ine monthly on a form. The IRS then uses these two pieces of information to calculate what the employer needs to contribute in FICA tax.
