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 US federal government imposes income tax on wages and salaries. This is the tax that is calculated on the Form 1040 each year. The federal income tax rate gradually or progressively becomes higher as income rises, and various deductions, exemptions, or tax credits lower the federal income tax.
