Reporting Tax Scams
Phishing is a scam typically carried out through unsolicited email and/or websites that pose as legitimate sites and lure unsuspecting victims to provide personal and financial information.
Report all unsolicited email claiming to be from the IRS or an IRS-related function to firstname.lastname@example.org . If you've experienced any monetary losses due to an IRS-related incident, please report it to the Treasury Inspector General Administration (TIGTA) and file a complaint with the Federal Trade Commission (FTC) through their Complaint Assistant to make the information available to investigators.
