Tax Day Cyber Threats: Protecting Employee W-2 Data

Tax season is a prime opportunity for cybercriminals to launch phishing attacks, with W-2 scams being one of the most dangerous threats to businesses. These scams target employers, HR departments, and payroll professionals, aiming to steal employee Social Security numbers and other sensitive tax data. If successful, hackers can commit identity theft, file fraudulent tax returns, or sell stolen information on the dark web.

What is a W-2 Phishing Scam?

W-2 phishing scams typically involve cybercriminals impersonating executives or HR personnel through email, requesting copies of employee W-2 forms. These emails often appear urgent and legitimate, tricking employees into handing over confidential tax information.

Common characteristics of W-2 phishing emails include:

• Spoofed Email Addresses – Attackers manipulate the sender’s email address to appear as a company executive or HR official.

• Urgent Language – Messages create a sense of urgency, demanding W-2 forms for ‘immediate review’ or ‘tax preparation.’

• Requests for Multiple Employees’ W-2s – Instead of targeting a single individual, attackers often ask for bulk employee tax forms.

• Links to Fake IRS Websites – Some phishing emails direct employees to fraudulent login pages designed to steal credentials.

Real-World Impact of W-2 Scams

Businesses across Florida, from small firms in Orlando to large corporations in Jacksonville, have been targeted by these scams. In past cases, companies unknowingly handed over W-2 data, leading to massive identity theft incidents. The IRS has repeatedly warned businesses about these attacks, urging companies to strengthen their cybersecurity defenses.

How to Protect Your Business from W-2 Phishing Scams

Businesses must take proactive steps to prevent tax-related cyber fraud. Here are some essential measures:

1. Train Employees to Recognize Phishing Emails

• Educate staff about W-2 phishing scams, teaching them how to spot red flags in emails.

• Conduct phishing simulations to test employees’ responses and improve awareness.

• Encourage employees to verify suspicious requests through direct communication.

2. Implement Strong Email Security Protocols

• Use email filtering systems to detect and block phishing attempts before they reach inboxes.

• Enable multi-factor authentication (MFA) to protect access to payroll and HR systems.

• Set up DMARC, SPF, and DKIM email authentication protocols to prevent email spoofing.

3. Restrict Access to W-2 Data

• Limit W-2 and payroll data access to only essential personnel.

• Use role-based access controls (RBAC) to prevent unauthorized users from handling tax information.

• Encrypt sensitive data to ensure it remains secure even if an account is compromised.

4. Verify All W-2 Requests

• Employees should confirm W-2 requests through a second communication method, such as a phone call.

• Set clear company policies that require verbal confirmation before sending sensitive tax data.

• The IRS does not send unsolicited emails requesting W-2s—warn employees against such scams.

5. Report Suspicious Emails Immediately

• If your business receives a suspected W-2 phishing email, report it to [email protected].

• Alert your IT team to investigate and block similar phishing attempts.

• If employee data has already been compromised, contact the IRS, FTC, and credit monitoring agencies to mitigate damage.
