## What’s New and Why It Matters
| Scam Type | What’s Different in 2026 | Why You Should Care |
|---|---|---|
| **Undistributed Long-Term Capital Gains abuse** | More fabricated Form 2439 claims tied to fake or misused organizations. ([irs.gov](https://www.irs.gov/newsroom/dirty-dozen-tax-scams-for-2026-irs-reminds-taxpayers-to-watch-out-for-dangerous-threats?utm_source=openai)) | Potential for IRS audits and penalties; refunds could be delayed or denied. |
| **AI and Impersonation Scams** | Use of social engineering, voice mimicry, phishing via QR codes, etc. ([irs.gov](https://www.irs.gov/newsroom/dirty-dozen-tax-scams-for-2026-irs-reminds-taxpayers-to-watch-out-for-dangerous-threats?utm_source=openai)) | Personal data exposed; identity theft risk; false claims can ruin credibility. |
## Compliance Best Practices
- **Authenticate sources**: Only rely on IRS notices from IRS.gov. If someone contacts via text/email, verify through official sites.
- **Maintain accurate records**: For any Form 2439 income or claims, ensure documentation from legitimate trusts or funds; don’t inflate or fictitious withholdings.
- **Engage credible professionals**: Avoid unregistered preparers; ensure they sign returns and list a valid PTIN. Ghost preparation is a red flag.
- **Stay informed about evolving threats**: Scams adapt. Monitor IRS announcements, alerts, and advisories.
## Example Scenarios
- **Scenario A**: Leslie is handed a 2439 form from what appears to be a real REIT but isn’t verifiable. Leslie verifies the financial statements and trust structure before using it to claim an exclusion.
- **Scenario B**: A business is approached by an agency or app demanding large upfront refunds or credits for “self-employment tax credits.” Business verifies that this credit actually exists and is legitimate; declines involvement if not certain.
## What To Do If You’re Targeted or Impacted
- Report scams immediately via IRS tip lines and form portals. ([irs.gov](https://www.irs.gov/newsroom/dirty-dozen-tax-scams-for-2026-irs-reminds-taxpayers-to-watch-out-for-dangerous-threats?utm_source=openai))
- Hold off filing a disputed Form 2439 until completely secure about its legitimacy.
- If identity theft is suspected, alert authorities and IRS identity theft units.
### Bottom Line
Compliance isn’t just about avoiding punishment—it’s about preserving reputation, peace of mind, and financial integrity. The Dirty Dozen list is a strong reminder: vigilance matters more than ever in 2026.
