Tax season has always been a busy time for cybercriminals—but this year, they’re using AI tools to create scams so realistic, even savvy clients are falling for them. According to recent reports, impersonation email and SMS scams targeting taxpayers have surged over 300%, and CPAs are being pulled directly into the chaos.
With deepfake audio, spoofed caller IDs, and fake IRS messages flooding inboxes and phones, your clients are at risk—and so is your firm’s reputation.
The Rise of AI-Powered Tax Scams
Modern scams are no longer sloppy, typo-riddled messages from mysterious senders. Today’s attackers are leveraging generative AI and deep learning to mimic real voices, fake documents, and craft hyper-personalized messages.
These scams often include:
Fake tax refund messages from what appears to be the IRS or your firm
SMS messages using spoofed phone numbers and urgent language
Deepfake voicemails pretending to be from accounting professionals
Malicious attachments that mimic tax return documents
The result? Clients are panicking, clicking, and exposing sensitive data—and sometimes blaming their accountant when things go wrong.
Why This Matters for Your Firm
Even if your systems aren't breached directly, your clients are being targeted—and many of those scams appear to come from trusted sources like you.
Here’s how this trend puts your firm at risk:
Client Confusion: Victims often forward the fake message to you, unsure if it’s real. Without clear security protocols or communication plans, it’s easy for trust to erode.
Reputation Damage: If scammers are impersonating your firm, any fallout—whether or not you're responsible—can affect your credibility.
Internal Risk: Staff members can also fall for advanced phishing attempts, especially those impersonating clients, IRS agents, or software vendors.
In short: Your clients are looking to you not only for financial guidance—but also for cyber safety.
What CPA Firms Should Do Right Now
Here’s how your firm can stay ahead of this wave of scams:
1. Educate Your Clients
Proactive education is your first line of defense:
Send out alerts about trending scams during tax season
Share real examples of phishing emails and messages
Remind clients to never click on unexpected links or provide info over text/email without verification
Pro Tip: We can help you create custom email templates or short videos you can send to clients with your branding.
2. Strengthen Your Internal Cyber Defenses
You’re only as strong as your weakest inbox. Make sure your team:
Uses Multi-Factor Authentication (MFA) across all devices and software
Undergoes cybersecurity awareness training, especially around phishing
Verifies unexpected emails or document requests—especially during tax season
Shield IT Networks offers employee phishing simulations and ongoing cybersecurity training tailored for CPA firms.
3. Have a Clear Client Communication Policy
Set expectations with clients so they know:
What type of messages they will (and won’t) receive from your firm
How to verify communications if something seems off
Who to contact in your office for suspicious messages
When clients trust that your firm is cyber-aware and communicative, they’re more likely to reach out—and less likely to panic or get scammed.
