The IRS is a bureau of the Department of the Treasury. 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.
