CRITICAL: IRS Credential Theft Targeting CPAs

Your Clients' Tax IDs AreBeing Sold Right NowOn the Dark Web

CPAs and accounting firms hold more sensitive financial data per square foot than almost any business on earth. Social security numbers, tax returns, bank accounts, payroll data โ€” all in one place.

The IRS reported over 3,000 tax-related data breaches in 2023 alone. Identity thieves file fraudulent returns the moment they steal client data. Your firm is the shortcut.

Client Tax Data Stolen

When hackers breach a CPA firm, they don't just steal data โ€” they file fraudulent tax returns before your clients can. The IRS holds your firm liable for inadequate data protection. Clients sue. Licenses get suspended.

SSNs and EINs used to file fraudulent returns instantly
Client bank accounts drained via ACH fraud
IRS holds firm liable for inadequate safeguards
Client lawsuits and license suspension possible

IRS & FTC Regulatory Exposure

The IRS Safeguards Program and FTC Safeguards Rule (updated 2023) require accounting firms to implement specific security controls โ€” MFA, encryption, access controls, vendor risk management. Non-compliance is not just a fine risk; it's a license risk.

FTC Safeguards Rule violations โ€” up to $50K+ per incident
IRS can revoke e-filing privileges
State CPA board disciplinary proceedings
Professional liability insurers may deny claims

Tax Season Shutdown

A ransomware attack during Januaryโ€“April is a firm-ending event. Client deadlines pass. Extensions must be filed. Clients leave. Staff are paid to do nothing. The most compressed, high-stakes window of the year becomes a catastrophe.

Tax filing deadlines missed โ€” penalty exposure for clients
QuickBooks, Drake, Lacerte systems locked or destroyed
Client relationships permanently damaged during peak season
Emergency IT costs on top of revenue loss

The Visibility Problem

Do You Really Know What'sGoing On With Your IT?

Most managing partners assume their IT is fine โ€” until a breach proves otherwise.

Does every staff member โ€” including seasonal hires โ€” use MFA on all firm systems?

When was your IRS-required written Data Security Plan last updated and tested?

Are client tax returns shared via encrypted portal, or still sent via email?

Do you know which third-party bookkeepers and payroll vendors have access to client data?

If a seasonal employee left today, how quickly could you revoke all their access?

Has your firm ever tested whether a departed employee's credentials still work?

If you couldn't answer those confidently โ€” you have a visibility gap.

Sentry Cloud IT gives you real-time dashboards, monthly security reports, and complete transparency into your IT health.
