When was the IRS created?

The Internal Revenue Service (IRS), the federal agency responsible for administering and enforcing tax laws in the United States, was officially created in its modern form in 1952. That year, under the administration of President Harry S. Truman, the existing Bureau of Internal Revenue underwent a sweeping reorganization to combat inefficiency and corruption, giving birth to the agency we now know as the IRS.

The origins of the IRS, however, trace back much earlier. The Bureau of Internal Revenue itself was first established in 1862 during President Abraham Lincoln’s administration, as a means to collect taxes to help fund the Civil War. Over the decades, the bureau evolved to oversee income tax collection and enforcement of tax laws following the ratification of the 16th Amendment in 1913, which gave Congress the power to impose a federal income tax.

By the early 1950s, the Bureau of Internal Revenue was struggling with widespread inefficiencies and public distrust. In response, President Truman ordered a full-scale reorganization to restore credibility and improve accountability within the federal tax collection system. This reorganization led to the creation of the Internal Revenue Service (IRS) in 1952, officially replacing the Bureau and modernizing the structure, oversight, and operations of federal tax administration.

The IRS’s formation in 1952 marked a pivotal moment in U.S. tax history, laying the foundation for today’s federal tax system and the agency’s ongoing responsibilities, which include processing tax returns, issuing refunds, enforcing tax law, and assisting taxpayers across the country.
