The Internal Revenue Service (IRS) is the U.S. federal agency responsible for administering and enforcing tax laws, collecting federal taxes, processing tax returns, issuing refunds, and overseeing compliance with the Internal Revenue Code. The IRS also manages taxpayer services, conducts audits, combats tax fraud, and provides guidance to individuals, businesses, and tax professionals.
As the nation’s primary tax authority, the IRS plays a central role in federal revenue collection, taxpayer education, regulatory enforcement, and financial reporting requirements for both individuals and organizations.
