The last day to send in your federal income tax to the Internal Revenue Service is April 15 of each year. The Constitution gave the federal government the power to collect taxes. The federal government needs money to pay the nation’s debts and to defend and provide for the needs of the country. When the country was young, it was difficult to raise money from the 13 original states. The government began collecting income tax for the first time through the Revenue Act of 1861. This was only temporary. In 1894, a flat-rate federal income tax was enacted, but the Supreme Court said this was unconstitutional. Finally, in 1913, the 16th Amendment was ratified. It gave Congress the power to collect income taxes. Today, “taxable income” is money that is earned from wages, self-employment, tips, and the sale of property. The government uses these taxes to keep our country safe and secure. It also tries to cure and prevent diseases through research. In addition, the government uses these taxes to educate children and adults, and build and repair our roads and highways. Taxes are used to do these things and many more.
