16th Amendment Forward: In 1913, with World War I looming, ratification of the 16th Amendment permanently established the income tax. The amendment gave Congress the authority to impose a tax on the income earned by both individuals and corporations. By 1918, government revenue generated from the income tax exceeded $1 billion for the first time, and topped $5 billion by 1920. The introduction of the mandatory withholding tax on employee wages in 1943 increased tax revenue to almost $45 billion by 1945.
Income tax generally is computed as the product of a tax rate times taxable income. The tax rate may increase as taxable income increases (referred to as graduated rates). Tax rates may vary by type or characteristics of the taxpayer.he US federal government imposed the first personal income tax, on August 5, 1861, to help pay for its war effort in the American Civil War - (3% of all incomes over US $800) ($20,999 in 2015 dollars).
