MINNEAPOLIS (AP) - Minnesota tax officials are maintaining their freeze on accepting TurboTax returns for now.

Intuit, the company behind TurboTax, resumed filings of state tax returns Friday evening with increased anti-fraud measures, a day after halting the process when Minnesota and other states reported a rise in fraudulent filings.

The Minnesota Department of Revenue says it's working to verify the new security measures and will keep doing so until it can assure Minnesotans that they can file TurboTax returns safely. The department hasn't said when the freeze might be lifted.

Minnesota Revenue learned of the problem Wednesday night. Some taxpayers reported that TurboTax returns already had been filed in their names with stolen personal information.

Intuit says its systems were not breached, and it believes the personal data was stolen elsewhere.
