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

Statutory Authority

We're organized to carry out the responsibilities of the Treasury secretary per Internal Revenue Code (IRC) Section 7801. The IRS was created based on the secretary's authority to administer and enforce the internal revenue laws.
