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 United States federal government taxes personal income using graduated scale. Income tax rates begin at 10% and gradually increase to 15%, then 25%, then 28%, then 33%, then 35%, and finally reaching a top rate of 39.6%. Each tax rate applies to a specific range of income. This range is called a tax bracket.
