1.1.1  IRS Mission and Basic Organization  (03-01-2006)
The IRS Mission

  1. The mission of the IRS is to " Provide America's taxpayers top quality service by helping them understand and meet their tax responsibilities and by applying the tax law with integrity and fairness to all. "

  2. This mission statement describes IRS' role and the public’s expectation about how IRS 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.  (03-01-2006)
Statutory Authority

  1. The IRS is organized to carry out the responsibilities of the secretary of the Treasury under IRC § 7801. The Secretary has full authority to administer and enforce the internal revenue laws and has the power to create an agency to enforce these laws. The IRS was created based on this legislative grant. IRC § 7803 provides for the appointment of a Commissioner of Internal Revenue to administer and supervise the execution and application of the internal revenue laws.  (03-01-2006)
