The US Constitution’s 16th Amendment, which took effect in 1913, authorizes the federal government to levy taxes on income, and is the basis for today’s federal income tax system. With the passage of the Current Tax Payment Act of 1943, employers are required to withhold and pay income tax on the behalf of their employees.
