INTEREST RATES; UNDERPAYMENTS AND OVERPAYMENTS

Published:  1987

Section 6621. - Determination of Interest Rate, 26 CFR 301.6621-1: Interest rate

  Interest rates; underpayments and overpayments. The rate of interest determined under section 6621 of the Code for the calendar quarter beginning July 1, 1987, will continue to be 8 percent for overpayments and 9 percent for underpayments.

  Section 6621 of the Internal Revenue Code establishes differential rates for allowance of interest on tax overpayments and assessment of interest on tax underpayments. Under section 6621(a)(1), the overpayment rate is the sum of the short-term federal rate plus 2 percentage points. Under section 6621(a)(2), the underpayment rate is the sum of the short-term federal rate plus 3 percentage points.

  Section 6621(b)(1) of the Code provides that the Secretary shall determine the short-term federal rate for the first month in each calendar quarter.

  Section 6621(b)(2) of the Code provides that the federal short- term rate determined under section 6621(b)(1) for any month shall apply during the first calendar quarter beginning after such month.

  Section 6621(b)(3) of the Code provides that the federal short- term rate for any month shall be the federal short-term rate determined during such month by the Secretary in accordance with section 1274(d), rounded to the nearest full percent (or, if a multiple of 1/2 of 1 percent, such rate shall be increased to the next highest full percent).

  Rounded to the nearest full percent, the federal short-term rate determined during the month of April 1987 is 6 percent. Accordingly, an overpayment rate of 8 percent and an underpayment rate of 9 percent are established for the calendar quarter beginning July 1, 1987. The rates apply to amounts bearing interest during that calendar quarter. The 9 percent rate also applies to estimated tax underpayments for the quarter.

  Interest factors for daily compound interest for annual rates of 8 percent and 9 percent were published in Tables 14 and 15 of Rev. Proc. 83-7, 1983-1 C.B. 583, 597, 598.

  Annual interest rates to be compounded daily pursuant to section 6622 of the Code that apply for prior periods are set forth in the following table:
