ST. PAUL, Minn. (AP) -

State officials are warning of a scam by a group posing as the Minnesota Department of Revenue that uses claims of tax refunds as bait to obtain personal data.

The department said Tuesday that the scammers are seeking personal or banking information of taxpayers. According to the department, callers going by "Minnesota Revenue" suggest they are seeking the information to process a larger tax refund.

The state agency says it doesn't call people about the size of their refunds.

Officials say they should report official emails or phone calls to the Department of Revenue.
