IRS Publishes Terminal Charge and SIFL Mileage Rates for January-June 2017

In Rev. Rul. 2017-10 the IRS has published the terminal charge and standard industry fare level mileage rates for the first six months of 2017.  These rates are used under Reg. §1.61-21(g)’s rule for valuing noncommercial flights on an employer-provided aircraft. 

The rates are revised every six months, and these rates cover flights occurring between January 1, 2017 and June 30, 2017.

As the ruling explains:

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 chart for the first six months of 2017 is provided below:
