The interest rate for the portion of a corporate overpayment exceeding $10,000 is 1.5 percent. The interest rates are computed by using the federal short-term rate based on daily compounding determined during July 2017.The Internal Revenue Code provides that the rate of interest is to be determined on a quarterly basis. For taxpayers other than corporations, the overpayment and underpayment rate is the federal short-term rate plus three percentage points. Generally, in the case of a corporation, the underpayment rate is the federal short-term rate plus three percentage points, and the overpayment rate is the federal short-term rate plus two percentage points.
