SIFL : What is SIFL

SIFL (Standard Industry Fare Level) is a method of taxing employees, family members, and guests when the company aircraft is used for personal reasons. 

Every six months the IRS determines the level of costs incurred by flying on a corporate aircraft in relation to the cost of a commercial airline, and imputes those amounts to the employee’s income for the year. 

The amounts are based on the mileage flown, weight of the aircraft, and the level of the employee within the company. Because all of the listed factors are used to calculate imputed income, it is important that fields in each database are filled in correctly.
