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.
In 1913, the 16th Amendment to the Constitution made the income tax a permanent fixture in the U.S. tax system. The amendment gave Congress legal authority to tax income and resulted in a revenue law that taxed incomes of both individuals and corporations. In fiscal year 1918, annual internal revenue collections for the first time passed the billion-dollar mark, rising to $5.4 billion by 1920.
