TurboTax on Friday said it had resumed the processing of state tax filings nationwide a day after Minnesota's Revenue Department quit accepting state returns filed with the tax software.
But Minnesota tax officials said they were keeping their freeze on TurboTax returns for now.
Intuit, which owns TurboTax, said it had halted filings for about 24 hours after it discovered "an increase in suspicious filings" related to identity theft and fraudulent tax refunds on Thursday. Nineteen states have noted potential fraud issues.
Minnesota's temporary halt was prompted by two taxpayers who logged into Intuit's TurboTax to file their state returns only to be told that their returns had already been filed. As of Friday afternoon, the state had not received any other calls about possible fraud. But it had not resumed processing TurboTax-prepared returns.
"We are working quickly to verify Intuit's new security measures and their impact on Minnesota returns," the department said in a statement Friday night. "We will work continuously until we can assure Minnesotans that TurboTax returns will be filed safely."
Intuit, based in Mountain View, Calif., indicated it was continuing to work with states and third-party security expert Palantir. Intuit believes the data breach didn't involve its systems but rather outside sources. The company has identified specific patterns of behavior where fraud is more likely to occur and is working with the states, including Minnesota, to share that information, said Brad Smith, Intuit president and CEO, in a statement on Intuit's website.
Those who have already filed their tax returns through TurboTax don't need to take any new action at this time. Federal income tax returns are not affected by the temporary delay, and taxpayers can continue to file with the IRSvia TurboTax.
Revenue officials said the state also isn't currently accepting paper returns from taxpayers affected by the TurboTax issue.
