Title 26 › Subtitle Subtitle D— - Miscellaneous Excise Taxes › Chapter CHAPTER 33— - FACILITIES AND SERVICES › Subchapter Subchapter C— - Transportation by Air › Part PART I— - PERSONS › § 4262
Defines what air travel is taxed for federal purposes. Flights that start and end in the United States or in places within 225 miles of the U.S. are taxed. Also taxed is any part of a flight that goes from one U.S. port to another U.S. port, unless that part is part of continuous international travel. "Continuous international travel" means the related flight pieces are scheduled with no more than 12 hours between them. "Transportation" also includes layovers, waiting time, and movement of the plane without passengers (deadhead). Parts of a flight that are entirely outside the United States are not taxed if they meet a few rules: the part is outside the U.S.; it starts where the route leaves the U.S. (or at a 225-mile-zone port) and ends where it re-enters the U.S. (or at a 225-mile-zone port); it is not serving certain connections with the 225-mile zone; and a straight line between those start and end points goes over a spot more than 225 miles from the U.S. The "continental United States" means the District of Columbia and the States except Alaska and Hawaii. The "225-mile zone" means parts of Canada and Mexico within 225 miles of the nearest point in the continental United States. The Treasury Secretary can agree with Canada or Mexico to exclude specified areas from the 225-mile zone, must publish a notice before the change is effective, and cannot publish that notice until 90 days after Congress’s tax committees get a copy.
