Cybercriminals are constantly evolving their tactics, and tax professionals remain one of their favorite targets. With access to sensitive taxpayer information, financial records, and personally identifiable information, tax offices are prime candidates for phishing attacks.

The IRS and its Security Summit partners recently issued a warning to tax professionals about five common phishing scams designed to steal client data, login credentials, and other sensitive information. As part of the "Protect Your Clients; Protect Yourself" campaign, the IRS is encouraging tax professionals to stay vigilant and strengthen their cybersecurity practices.

Here are the five phishing scams every tax office should know about—and how to help protect your business.

1. Traditional Phishing Emails

Phishing emails are one of the most common ways cybercriminals attempt to gain access to your systems.

These emails often appear to come from trusted organizations, clients, financial institutions, or even the IRS. They typically include links to fake websites or attachments designed to install malware or steal login credentials.

How to protect yourself:

• Never click suspicious links or unexpected attachments.

• Verify the sender's email address carefully.

• When in doubt, contact the sender using a known phone number or email—not the information provided in the suspicious message.

  
  

2. Spear Phishing

Unlike generic phishing emails, spear phishing is highly targeted.

Attackers often research your business and personalize emails using employee names, client information, or company details to make the message appear legitimate. These attacks can be especially convincing because they feel personal.

Tip: Even if an email references your business or a specific employee, take a moment to verify its authenticity before responding.

3. Whaling Attacks

Whaling is a specialized form of spear phishing that targets business owners, partners, managers, or other individuals with elevated access.

These attacks often request wire transfers, login credentials, payroll information, or sensitive client records. Because they target decision-makers, the financial impact can be significant.

Best practice: Require a second level of approval before processing financial requests or sharing confidential information.

4. Clone Emails

A clone email is a copy of a legitimate email you've previously received—but with one important difference.

Cybercriminals replace the original attachment or link with a malicious version while making the message appear authentic. Since the email looks familiar, recipients are often more likely to trust it.

Always verify unexpected follow-up emails, even if they appear to be part of an existing conversation.

5. Fake "New Client" Emails

Tax professionals are increasingly seeing emails from individuals claiming to be new clients looking for help with tax preparation.

While some inquiries are genuine, scammers often attach malicious files disguised as tax documents or ask you to download information from unsafe links. Opening these files can install malware that compromises your entire office.

If a new client sends unexpected attachments, verify their identity before opening any files.

Simple Ways to Strengthen Your Tax Office's Security

While no system is immune to cyber threats, a few best practices can significantly reduce your risk:

• Enable multi-factor authentication (MFA) on all business accounts.

• Keep software and operating systems updated.

• Train employees to recognize phishing attempts.

• Use strong, unique passwords.

• Back up important client data regularly.

• Develop a Written Information Security Plan (WISP) if you haven't already.

  
  

Why This Matters

Tax professionals are trusted with some of their clients' most sensitive information. A successful phishing attack doesn't just put your business at risk—it can impact every client you serve.

Taking a few extra moments to verify emails, train your staff, and follow cybersecurity best practices can help prevent costly data breaches and protect the trust you've worked hard to build.
