TurboTax Customers

You may have seen recent news reports regarding TurboTax and its parent company, Intuit. On Thursday, February 5, 2015, TurboTax/Intuit temporarily stopped transmitting state e-filing tax returns. Transmission resumed the following day.

According to TurboTax/Intuit: "The resumption comes after the company temporarily paused transmissions upon seeing an increase in suspicious filings and attempts by criminals to use stolen identity information to file fraudulent state tax returns and claim tax refunds."

TurboTax/Intuit went on to say that "...[after] a preliminary examination of recent fraud activities, Intuit believes that these instances of fraud did not result from a security breach of its systems."
