(KAIT/NBC) - The tax filing deadline is just days away, but experts warn of the dangers connected to using a mobile device to finish returns.
Most of the major tax software companies offer mobile filing. The IRS has an app as well.
However, financial experts warn that doing your taxes on a mobile device could create data vulnerabilities. Most of the apps require a photo of a W-2, but that sensitive data can easily be stolen.
After uploading tax documents, many people forget to delete the photos. Photos may sit in a phone's storage and possibly the cloud inviting hackers.
Scammers can also use malware to steal tax account logins. According to Symantec, mobile malware increased by 54 percent in 2017. One defense experts suggest is not using a public WiFi network.
"If you're sitting in a coffee shop fast food restaurant and you decide to do your tax return you don't know who's out there lurking around who could hop on your phone and get access to your most sensitive information," said Megan Gorman, Chequers financial management.
NBC contacted TurboTax, H&R Block, TaxSlayer and TaxAct to get their response to these security concerns.
TurboTax and H&R Block responded and said security and protecting their client's information is a top priority. TurboTax noted that its app does not store any data on a customer's phone or device.
H&R Block said the photos taken with its mobile app are not saved to the device or the cloud and are removed from the client's device after upload. That usually takes 10 to 15 seconds.
