DRAFTING INFORMATION

The principal author of this revenue ruling is John Roman Faron of the Office of Associate Chief Counsel (Income Tax and Accounting). For further information regarding this revenue ruling, contact Mr. Faron at (202) 622–8142 (not a toll-free call).

Section 481.—Adjustments Required by Changes in Method of Accounting

This revenue procedure provides the exclusive procedures under which a taxpayer may make certain changes to, from, or within a nonaccrual-experience (NAE) method of accounting with an adjustment under section 481(a) of the Code and changes that may be made using a cut-off method. See Rev. Proc. 2006-56, page 1169.

Section 6621.—Determina- tion of Rate of Interest

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 January 1, 2007, will be 8 percent for overpayments (7 percent in the case of a corporation), 8 percent for underpayments, and 10 percent for large corporate underpayments. The rate of interest paid on the portion of a corporate overpayment exceeding $10,000 will be 5.5 percent.

Rev. Rul. 2006–63

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 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)(2)(B) provides that in determining the addition to tax under section 6654 for failure to pay estimated tax for any taxable year, the federal short-term rate that applies during the third month following such taxable year also applies dur

ing the first 15 days of the fourth month following such taxable year.

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 § 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 October 2006 is 5 percent. Accordingly, an overpayment rate of 8 percent (7 percent in the case of a corporation) and an underpayment rate of 8 percent are established for the calendar quarter beginning January 1, 2007. The overpayment rate for the portion of a corporate overpayment exceeding $10,000 for the calendar quarter beginning January 1, 2007, is 5.5 percent. The underpayment rate for large corporate underpayments for the calendar quarter beginning January 1, 2007, is 10 percent. These rates apply to amounts bearing interest during that calendar quarter.

The 8 percent rate also applies to estimated tax underpayments for the first calendar quarter in 2007 and for the first 15 days in April 2007.

for prior periods are set forth in the tables accompanying this revenue ruling.
