Whether you've got a mild stomachache, sharp pain, or cramps, abdominal pain can have many causes. For instance, you might have indigestion, constipation, a stomach virus, or, if you're a woman, menstrual cramps.
When did Congress start taxing income? It was on August 5th in 1861 when the federal government of the U.S. first imposed taxes on income. In relation to the Civil War during that time, the primary purpose of such practice was to gather funding to help finance the war. It was implemented right after the signing of the Revenue Act of 1861.
The rate of tax at the federal level is graduated; that is, the tax rates of higher amounts of income are higher than on lower amounts. Some states and localities impose an income tax at a graduated rate, and some at a flat rate on all taxable income. The highest marginal tax rate for individuals for U.S. federal income tax purposes for tax years 1952 and 1953 was 92%. 2  Since 1964, the threshold for paying top income tax rate has generally been between $200,000 and $400,000.
