What steps did the federal government take to ensure that the tax was collected?

The federal government implemented various measures to ensure tax collection, including establishing the Internal Revenue Service (IRS) to oversee tax administration and enforcement. They employed a range of compliance strategies, such as audits, penalties for late payments, and the withholding of taxes directly from wages. Additionally, the government utilized data matching and information sharing with financial institutions to track income and ensure accurate reporting. These steps collectively aimed to enhance compliance and minimize tax evasion.
