16. Fringe Benefits: SIFL Rates

For purposes of taxing fringe benefits under Section 61, Reg. section 1.61-21(g) provides a rule for valuing noncommercial flights on employer-provided aircraft and Reg. section 1.61-21(g)(5) provides an aircraft valuation formula to value such flights. The value of a flight is determined under the base aircraft valuation formula (also known as the standard industry fare level formula (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 Reg. section Reg. 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 Transportation Department and are reviewed semi-annually.

The following revenue rulings contain tables setting forth the terminal charges and SIFL mileage rates for 1994-2024.
