 An accounting error could mean more money in your pocket next year. Earlier this year, a statewide audit discovered a multi-million dollar mistake resulting in Colorado taxpayers being owed millions more in Tabor refunds. It came from a bill that charges tax on health insurance premiums. Those taxes collected were thought to be Tabor exempt, but the audit and Attorney General concluded that this was Tabor revenue, and the state owes taxpayers nearly $34 million.
