Internal Revenue Service (IRS)
The IRS Criminal Investigation division enforces the nation's tax laws through investigation and prosecution of tax crimes, money laundering, and related financial offenses. The IRS also pursues civil enforcement through audits, penalties, tax liens, and levies. The agency's enforcement budget has significantly increased under the Inflation Reduction Act, enabling expanded compliance operations targeting high-income non-filers and abusive tax schemes.
