Rev. Rul. 2005-61


Table of Contents

Fringe benefits aircraft valuation formula. The Standard Industry Fare Level (SIFL) cents-per-mile rates and terminal charges in effect for the second half of 2005 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.

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 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 charges and SIFL mileage rates:

Period During Which the Flight Is Taken Terminal Charge SIFL Mileage Rates
7/1/05 - 12/31/05 $35.21 Up to 500 miles = $.1926 per mile
    501-1500 miles = $.1468 per mile
    Over 1500 miles = $.1412 per mile
