CPA & Tax Composite/dramatized

Look what happened to this tax office, so it doesn't happen to yours

By FraudMeNot Team

Label: Composite/dramatized. "Composite story based on common real-world patterns. Names, places and numbers are invented." (Patterns from IRS / Security Summit warnings; not based on any single real firm.)

The story (composite)

It's the middle of filing season at a three-person tax office. An email comes in from a "new client": polite, a little rushed, with a "prior-year return" attached and a request to take a look before an appointment. The preparer clicks. Nothing seems to happen.

Over the next few weeks, the office's software logins are quietly captured. Later, someone files returns using client data, and the office finds out when clients' real returns get rejected.

What the IRS says is real

• The IRS and Security Summit list "new client" schemes as a form of spear phishing: fraudsters pose as prospective clients and send malicious links or attachments disguised as tax documents. (Sources 1, 2)
• They also warn about phishing aimed at preparers' EFIN, PTIN, and CAF numbers, and about clone phishing, where a copy of a real email carries a malicious link. (Sources 1, 2)
• Tax pros need a Written Information Security Plan (WISP). (Source 3, IRS summer series list, IR-2026-92)

The moment it could have been stopped

The attachment from someone who wasn't a client yet.

Tips (general)

1. Run every new-client intake through a secure portal, not email attachments.
2. Be suspicious of urgency, duplicate emails with a "new" link, and misspelled domains (Source 2).
3. Use multi-factor authentication on tax software and email.
4. Per the IRS, forward suspicious spear-phishing emails as attachments to [email protected] with the subject "Spearphishing," and report to TIGTA. If you suspect a breach, contact your IRS Stakeholder Liaison quickly. (Sources 1, 4)
5. Keep your WISP current and train staff on it.
