Section 61.—Gross Income Defined

26 CFR 1.61–21: Taxation of fringe benefits.

Fringe benefits aircraft valuation for- mula. The Standard Industry Fare Level (SIFL) cents-per-mile rates and terminal charge in effect for the first half of 2010 are set forth for purposes of determining the value of noncommercial flights on employer-provided aircraft under section 1.61–21(g) of the regulations.

Period During Which the Flight Is Taken

Rev. Rul. 2010–10

For purposes of the taxation of fringe benefits under section 61 of the Internal Revenue Code, section 1.61–21(g) of the Income Tax Regulations provides a rule for valuing noncommercial flights on employer-provided aircraft. Section 1.61–21(g)(5) provides an aircraft valuation formula to determine the value of such flights. The value of a flight is determined under the base aircraft valuation formula (also known as the Standard Industry Fare

Terminal Charge

Level formula or SIFL) by multiplying the SIFL cents-per-mile rates applicable for the period during which the flight was taken by the appropriate aircraft multiple provided in section 1.61–21(g)(7) and then adding the applicable terminal charge. The SIFL cents-per-mile rates in the formula and the terminal charge are calculated by the Department of Transportation and are reviewed semi-annually.

The following chart sets forth the terminal charge and SIFL mileage rates:

SIFL Mileage Rates

1/1/10 - 6/30/10 $40.28 Up to 500 miles = $.2204 per mile

501-1500 miles = $.1680 per mile

Over 1500 miles = $.1615 per mile

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 that 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 the taxable year also applies during the first 15 days of the fourth month following the taxable year. Section 6621(b)(3) provides that the federal short-term rate for any month is the federal short-term rate determined during that 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, the rate is increased to the next highest full percent).

Section 6621.—Determina- tion of Rate of Interest

26 CFR 301.6621–1: Interest rate.

Interest rates; underpayments and overpayments. The rates for interest determined under section 6621 of the Code for the calender quarter beginning April 1, 2010, 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.

Rev. Rul. 2010–9

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. 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

2010–13 I.R.B. 461 March 29, 2010

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.

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.

The federal short-term rate determined in accordance with section 1274(d) during January 2010 is the rate published in Revenue Ruling 2010–6, 2010–6 I.R.B. 387 to take effect beginning February 1, 2010. The federal short-term rate, rounded to the nearest full percent, based on daily compounding determined during the month of January 2010 is 1 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 April 1, 2010. The overpayment rate for the portion of a corporate overpayment exceeding $10,000 for the calendar quarter beginning April 1, 2010, is 1.5 percent. The underpayment rate for large corporate underpayments for the calendar quarter beginning April 1, 2010, is 6 percent. These rates apply to amounts bearing interest during that calendar quarter.

Under section 6621(b)(2)(B), the rate for determining the addition to tax for failure to pay estimated tax for the first 15 days in April 2010 is the 4 percent rate that applied to underpayments of tax during the first calendar quarter in 2010.

Interest factors for daily compound interest for annual rates of 1.5 percent, 3 percent, 4 percent, and 6 percent are published
