When did the IRS start and why?

Answer 1

The IRS began in July 1863 during the Civil War, when President Abraham Lincoln and Congress created the office of Commissioner of Internal Revenue and enacted a temporary income tax to pay war expenses. The position of Commissioner exists today as the head of the Internal Revenue Service.

The Revenue Act of 1862 was passed as an emergency and temporary war-time tax. It copied a relatively new British system of income taxation, instead of trade and property taxation. The first income tax was passed in 1861.

However, in 1872, seven years after the war, lawmakers allowed the temporary Civil War income tax to expire. Income taxes evolved, but in 1894 the Supreme Court declared the Income Tax of 1894 unconstitutional in Pollock v. Farmers' Loan & Trust Co.. The federal government scrambled to raise money.

In 1906, with the election of President Theodore Roosevelt, and later his successor William Howard Taft, the United States saw a populist movement for tax reform. This movement culminated during then candidate Woodrow Wilson's election of 1912 and in February, 1913, the ratification of the Sixteenth Amendment to the United States Constitution: "The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration."

In the first year after ratification of the Sixteenth Amendment, no taxes were collected-instead, taxpayers simply completed the form and the IRS checked it for accuracy. The IRS's workload jumped by ten-fold, triggering a massive restructuring. Professional tax collectors began to replace a system of "patronage" appointments. The IRS doubled its staff, but was still processing 1917 returns in 1919.

The 1980s saw a reorganization of the IRS. A bipartisan commission was created with several mandates, among them to increase customer service and improve collections. Congress later enacted the Internal Revenue Service Restructuring and Reform Act of 1998. As a result of that Act, the IRS now functions under four major operating divisions: Large Business and International division (LB&I), the Small Business/Self-Employed (SB/SE) division, the Wage and Investment (W&I) division, and Tax Exempt & Government Entities (TE/GE) division. Effective October 1, 2010, the name of the Large and Mid-Size Business division changed to the Large Business & International (LB&I) division.
