The Internal Revenue Service has announced that interest rates for the calendar quarter beginning January 1, 2000, will remain at 8 percent for overpayments (7 percent in the case of a corporation), 8 percent for underpayments, and 10 percent for large corporate underpayments.
The overpayment rate for the portion of a corporate overpayment exceeding $10,000 will remain at 5.5 percent%.
The interest rates are computed from the federal short-term rate based on daily compounding determined during October 1999.
