Title 49 › SUBTITLE IV — INTERSTATE TRANSPORTATION › PART B — MOTOR CARRIERS, WATER CARRIERS, BROKERS, AND FREIGHT FORWARDERS › CHAPTER 145 — FEDERAL-STATE RELATIONS › § 14503
Motor and motor private carriers covered by subchapter I of chapter 135 must only have state income tax taken out for the state (or part of the state) where the employee lives when that employee regularly works in two or more states. Employee is defined in section 31132. If an employee spends more than 50 percent of their work time in one state in a year, they are treated as having earned more than 50 percent of their pay there. Water carriers covered by subchapter II of chapter 135 must send tax forms and reports only to the employee’s state of residence and to any state where the employee earned more than 50 percent of pay during the preceding calendar year. That water-carrier rule also applies to masters, officers, and sailors on vessels in foreign, coastwise, intercoastal, noncontiguous trade, or U.S. fisheries. Motor carriers who withhold under the first rule must file tax reports only with the employee’s state of residence.
