 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 October 1, 2003, will be 4 percent for overpayments (3 percent in the case of a corporation), 4 percent for

underpayments, and 6 percent for large corporate underpayments. The rate of interest paid on the portion of a corporate overpayment exceeding $10,000 will be 1.5 percent.

  Interest rates; underpayments and overpayments. The rate of interest determined under section 6621 of the Code for the calendar quarter beginning October 1, 2003, will be 4 percent for overpayments (3 percent in the case of a corporation), 4 percent for underpayments, and 6 percent for large corporate underpayments. The rate of interest paid on the portion of a corporate overpayment exceeding $10,000 will be 1.5 percent.

  Section 6621 of the Internal Revenue Code establishes the rates for interest on tax overpayments and tax underpayments. Under section 6621(a)(1), the overpayment rate beginning October 1, 2003, is the sum of the federal short-term rate plus 3 percentage points (2 percentage points in the case of a corporation), except the rate for the portion of a corporate overpayment of tax exceeding $10,000 for a taxable period is the sum of the federal short-term rate plus 0.5 of a percentage point for interest computations made after December 31, 1994. Under section 6621(a)(2), the underpayment rate is the sum of the federal short-term rate plus 3 percentage points.

  Section 6621(c) provides that for purposes of interest payable under section 6601 on any large corporate underpayment, the underpayment rate under section 6621(a)(2) is determined by substituting “5 percentage points” for “3 percentage points.” See section 6621(c) and section 301.6621-3 of the Regulations on Procedure and Administration for the definition of a large corporate underpayment and for the rules for determining the applicable date. Section 6621(c) and section 301.6621-3 are generally effective for periods after December 31, 1990.

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

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

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

  Notice 88-59, 1988-1 C.B. 546, announced that, in determining the quarterly interest rates to be used for overpayments and underpayments of tax under section 6621, the Internal Revenue Service will use the federal short-term rate based on daily compounding because that rate is most consistent with section 6621 which, pursuant to section 6622, is subject to daily compounding.

  Rounded to the nearest full percent, the federal short-term rate based on daily compounding determined during the month of July 2003 is I percent. Accordingly, an overpayment rate of 4 percent (3 percent in the case of a corporation) and an underpayment rate of 4 percent are established for the calendar quarter beginning October 1, 2003. The overpayment rate for the portion of a corporate overpayment exceeding $10,000 for the calendar quarter beginning October 1, 2003, is 1.5 percent. The underpayment rate for large corporate underpayments for the calendar quarter beginning October 1, 2003, is 6 percent. These rates apply to amounts bearing interest during that calendar quarter.

  Interest factors for daily compound interest for annual rates of 1.5 percent, 3 percent, 4 percent, and 6 percent are published in Tables 8, 11, 13, and 17 of Rev. Proc. 95-17, 1995-1 C.B. 556, 562, 565, 567, and 571.

  Annual interest rates to be compounded daily pursuant to section 6622 that apply for prior periods are set forth in the tables accompanying this revenue ruling.
