SIM Swap Fraud During Tax Season
By Greg Collier
With millions of Americans filing their taxes between January and mid-April, this period becomes fertile ground for digital deception. One particularly insidious tactic gaining traction is SIM swap fraud, a type of identity theft that can occur without a scammer ever touching your phone.
A recent case in Wisconsin highlights how easily a seemingly routine moment can spiral into a security breach. A consumer had just begun the tax filing process in early February when she received a message claiming to be from a TurboTax. The message included a security code and instructions not to share it with anyone. Although she had not completed her filing with TurboTax, the timing and branding appeared legitimate, prompting her to interact with the message.
What followed was a total loss of cellular function. Phone calls, text messages, and all forms of communication stopped working. After reaching out to her wireless provider, she learned that her phone number had been transferred to another device entirely. This is the essence of SIM swap fraud, a scam that allows criminals to reroute your phone number to their device without needing physical access to yours.
This tactic enables scammers to intercept text messages, including those containing security codes used for two-factor authentication. Once they’re in control of your number, they can attempt to access your financial accounts, email, or even social media, often using brute force or previously stolen credentials.
In this particular case, the victim’s credit union was contacted by someone impersonating her, attempting to guess account passwords. Fortunately, the breach was detected in time and no funds were lost. However, the emotional toll was significant. The sense of violation left the victim unable to feel secure, questioning whether every online interaction was truly safe.
While this incident happened soon after she began filing taxes through TurboTax, it is important to note that the platform itself was not compromised. The timing was purely coincidental. Scammers often cast a wide net, sending messages disguised as major companies to thousands of random numbers, hoping that even a few people will take the bait.
Preventing this type of fraud requires preparation. Consumers should ensure that all software on their devices is up-to-date and avoid reusing passwords across accounts. Writing down passwords and storing them in a secure location is preferable to saving them on digital devices, which can be more easily compromised. Contact information for banks or financial institutions should be sourced independently, rather than trusted from unsolicited messages.
One of the most effective steps consumers can take to prevent SIM swap fraud is to contact their mobile phone provider and request that a personal identification number be added to their account. This PIN acts as an additional layer of security, making it significantly harder for scammers to transfer your phone number without your permission.
Without the correct PIN, even a scammer who has obtained some of your personal information will be blocked from making changes to your account. Setting up this PIN typically takes just a few minutes but can offer long-term protection against one of the most dangerous forms of digital identity theft.
When in doubt, it is always safer to pause before acting. Messages that demand immediate action or contain subtle grammatical errors are red flags. Even if a message appears to come from a trusted source, verifying it through official channels can prevent irreversible damage.
Scammers are persistent and adaptive, but so are the tools and strategies available to stay ahead of them. Awareness, skepticism, and a methodical approach to digital security remain the strongest defense against schemes like SIM swap fraud, especially during high-risk seasons like tax time.
