Each year, the IRS releases its "Dirty Dozen" list of common scams and schemes that taxpayers should be aware of.

The 2026 list includes:

• IRS impersonation by email and text (phishing + smishing). Scammers send emails, direct messages (DMs), and texts that appear to be from the IRS, often using alarming language and QR codes that direct taxpayers to fake IRS websites to “verify” accounts, enter personal information, or claim refunds. 
• AI-enabled IRS impersonation by phone (robocalls, voice mimicry, spoofed called ID). Phone scams continue to evolve, including calls that use computer-generated tactics and spoofed caller ID to appear legitimate. 
• Fake charities. Fraudsters often exploit tragedies and disasters by creating fake charities to collect donations and personal information.
• Misleading tax advice on social media. Viral “tax hacks” can push taxpayers to file returns with false information or claim credits they don’t qualify for, leading to refund delays, audits, penalties, or worse. 
• Identify theft involving IRS Online Account access. Criminals may attempt to use stolen personal information to gain unauthorized access to a taxpayer’s IRS online account or may pose as helpers to collect sensitive information during account setup. 
• Abusive undistributed long-term capital gain claims. The IRS identified an increase in the abuse of Form 2439. This form allows shareholders of certain investment funds or real estate trusts to claim a refundable credit for taxes paid on undistributed capital gains.
• Bogus “Self-Employment Tax Credit” promotion. Scammers use misleading claims about a broad “self-employment tax credit” to encourage inaccurate filings and generate improper refunds. 
• Ghost preparers. A “ghost” preparer prepares a return but refuses to sign it and/or refuses to include a Preparer Tax Identification Number (PTIN).
• Non-cash charitable contribution schemes. Some schemes involve inflated appraisals of donated property using syndicated conservation easements or art. 
• Overstated withholding schemes (fabricated wage/withholding data). Scammers encourage taxpayers to inflate withholding amounts (sometimes described as “other withholding”) to manufacture a larger refund by reporting zero or little income on incorrect forms. 
• Spear-phishing and malware campaigns targeting tax professionals. Tax professionals and businesses remain targets of “new client” or “document request” emails that deliver malicious links or attachments to steal client data or access systems.
• Aggressive or misleading Offer in Compromise marketing (“OIC mills”). The Offer in Compromise program can help certain eligible taxpayers resolve tax debt when they are unable to pay in full, but “OIC mills” often overpromise results and charge high fees to taxpayers who don’t qualify. 

The IRS emphasizes that taxpayers are legally responsible for what's on their tax returns and advises consulting with reputable tax professionals.
