WASHINGTON ― The Internal Revenue Service today announced that interest rates will remain the same for the calendar quarter beginning July 1, 2017. The rates will be:
Under the Internal Revenue Code, the rate of interest is determined on a quarterly basis. For taxpayers other than corporations, the overpayment and underpayment rate is the federal short-term rate plus 3 percentage points.
Generally, in the case of a corporation, the underpayment rate is the federal short-term rate plus 3 percentage points and the overpayment rate is the federal short-term rate plus 2 percentage points. The rate for large corporate underpayments is the federal short-term rate plus 5 percentage points. The rate on the portion of a corporate overpayment of tax exceeding $10,000 for a taxable period is the federal short-term rate plus one-half (0.5) of a percentage point.
The interest rates announced today are computed from the federal short-term rate determined during April 2017 to take effect May 1, 2017, based on daily compounding.
