WASHINGTON — The Internal Revenue Service today announced that interest rates will remain the same for the calendar quarter beginning October 1, 2020. The rates will be:   3% for overpayments (2% in the case of a corporation); 0.5% for the portion of a corporate overpayment exceeding $10,000; 3% percent for underpayments; and 5% percent for large corporate underpayments. 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.
