AccountAbility Minnesota aims to help taxpayers keep every penny of it. One way they do that is by offering low cost “refund anticipation loans,” which loan people money up front against the tax refund they are expecting. AccountAbility Minnesota charges no more than $30 for such a loan, compared to the hefty prices charged by commercial tax services like H&R Block and Jackson Hewitt. They charge fees ranging into the hundreds of dollars and interest rates as high as 500 percent.
