Internal Revenue Service

Provide America's taxpayers top quality service by helping them understand and meet their tax responsibilities and enforce the law with integrity and fairness to all.

This mission statement describes our role and the public’s expectation about how we should perform that role.

In the United States, the Congress passes tax laws and requires taxpayers to comply.
The taxpayer’s role is to understand and meet his or her tax obligations.
The IRS role is to help the large majority of compliant taxpayers with the tax law, while ensuring that the minority who are unwilling to comply pay their fair share.

Origin
The roots of IRS go back to the Civil War when President Lincoln and Congress, in 1862, created the position of commissioner of Internal Revenue and enacted an income tax to pay war expenses. The income tax was repealed 10 years later. Congress revived the income tax in 1894, but the Supreme Court ruled it unconstitutional the following year.

16th Amendment
In 1913, Wyoming ratified the 16th Amendment, providing the three-quarter majority of states necessary to amend the Constitution. The 16th Amendment gave Congress the authority to enact an income tax. That same year, the first Form 1040 appeared after Congress levied a 1 percent tax on net personal incomes above $3,000 with a 6 percent surtax on incomes of more than $500,000.

In 1918, during World War I, the top rate of the income tax rose to 77 percent to help finance the war effort. It dropped sharply in the post-war years, down to 24 percent in 1929, and rose again during the Depression. During World War II, Congress introduced payroll withholding and quarterly tax payments.

A New Name
In the 50s, the agency was reorganized to replace a patronage system with career, professional employees. The Bureau of Internal Revenue name was changed to the Internal Revenue Service. Only the IRS commissioner and chief counsel are selected by the president and confirmed by the Senate.

Today’s IRS Organization
The IRS Restructuring and Reform Act of 1998 prompted the most comprehensive reorganization and modernization of IRS in nearly half a century. The IRS reorganized itself to closely resemble the private sector model of organizing around customers with similar needs.
