Business corporations, like individuals, must pay taxes on their income In 1966 the corporation income tax provided 23 percent of all government receipts. By 1983 the figure had dropped to 6.2 percent, but by 1987 it climbed to 10.2 percent. The corporation income tax is often criticized as double taxation(税收). Not only must the company pay taxes on its profits, but individual shareholders(股东) must also pay personal income taxes on dividend(红利) income. The small stockholder has been given some relief by the provision allowing taxpayers to deduct(扣除) the fist $100 they receive in dividends from their personal income. In addition, money that is gained from the increase in the value of stock sold at least six months after its purchase considered a capital gain. The law allows the seller of such stock to pay a lower tax tate on the capital gain. However, gains from stock owned for less than six months are taxed at the rate of regular income. Many business people have complained—probably with some justification—that high corporate taxes interfere with their opportunities to reinvest their profits in their businesses. Such interference can hinder(妨碍) the growth and modernization of businesses. Some industrial nations that have expanded rapidly in the last 15 years have far lower taxes on corportations than the United States does. Many economists believe that low corporation taxes have been a help in this business expansion. A corporation income tax is based on a corporation's annual income after it has paid its expenses. Dividends to stockholders are not included as expenses. Recent changes in the tax have reduced the rates in order to encourage business investment in research and new capital equipment. The new rates are more progressive, increasing from 15 percent on the first $25,000 of taxable income to 46 percent on all taxable income above $100,000. The incidence of the tax tends to fall on the stockholders in highly competitive business because shifting the tax to the consumer would raise prices and cut down on sales.
