The U.S. Department of Transportation (DOT) has updated its standard industry fare level (SIFL) rates for the second half of the year, softening its unadjusted levels slightly over those in the first six months. SIFL rates are used for determining values of non-business transportation aboard employer-provided aircraft as required by the IRS. The DOT calculates the rates using airline cost and seat mile data and has published multiple versions to account for government relief received by air carriers during the pandemic, NBAA has advised.
For the period of July 1 to December 31, the unadjusted SIFL rates are $0.2417 for flights up to 500 miles, $0.1843 for between 501 and 1,500 miles, and $0.1771 for more than 1,500 miles. The terminal charge is $44.18. This compares with the first half rates of $0.2460 (up to 500 miles), $0.1876 (between 501 and 1,500), and $0.1803 (more than 1,500). The updated terminal charge also is lower than the $44.98 in the first half.
Adjusting for Payroll Support Program (PSP) grants, second-half SIFL rates are $0.2460 (up to 500 miles), $0.1875 (between 501 and 1,500), and $0.1803 (more than 1,500), with a $44.97 terminal charge. Adjusting for PSP and promissory notes during the latter half of the year, the rates are, respectively, $0.2562, $0.1953, and $0.1878, with a $46.83 terminal charge.
