IRS

The mission of the IRS is to 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.
