WASHINGTON — The Internal Revenue Service today announced there will be no change in the interest rates for the calendar quarter beginning Oct. 1, 2007. The interest rates are as follows: 

  • 8 percent for overpayments (7 percent in the case of a corporation);
  • 8 percent for underpayments;
  • 10 percent for large corporate underpayments; and
  • 5.5 percent for the portion of a corporate overpayment exceeding $10,000.

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 0.5 of a percentage points.

The interest rates announced today are computed from the federal short-term rate based on daily compounding determined during July 2007.
