The term 'Internal Revenue Collections' refers to the process of collecting taxes from individuals and businesses. This is done by the Internal Revenue Service (IRS), which is a federal agency responsible for administering and enforcing the tax laws of the United States. The IRS collects taxes from individuals and businesses through various methods, including withholding taxes from wages, filing returns, and assessing penalties for non-payment. The money collected is then used to fund government programs and services.
