Do truck drivers pay state income tax in every state they drive through?

No, not on their wages. Under 49 U.S.C. 14503(a)(1), the pay of a motor carrier employee who performs regularly assigned duties in 2 or more states is subject to state income tax only in the state of residence. States the route passes through do not tax that pay.

Which state withholds tax from a company driver?

The state of residence. Section 14503(c) also limits the carrier: a motor carrier or motor private carrier withholding under the rule files its income tax information returns and reports only with the state and subdivision of the employee’s residence.

Does the rule cover owner-operators?

No. Section 14503 speaks to compensation paid to an employee of a motor carrier or motor private carrier. An owner-operator running under their own authority has business income, not wages from a carrier, and this federal wage rule does not decide how a state taxes that income.

What if a driver only works inside one state?

The single-state protection is written for an employee who performs regularly assigned duties in 2 or more states. A driver whose assigned duties stay in one state is outside the sentence the statute protects, and normal state rules for residents and nonresidents apply.

Does this change IFTA or IRP?

No. IFTA fuel tax and IRP apportioned registration are taxes and fees on the vehicle and the carrier’s operation, apportioned by miles. Section 14503 covers an employee’s income tax on pay. The two systems sit side by side and neither cancels the other.

Where is this rule written?

Title 49 of the U.S. Code, section 14503, headed "Withholding State and local income tax by certain carriers." Subsection (a)(1) holds the single-state rule, (a)(2) borrows the employee definition from 49 U.S.C. 31132, and subsection (c) holds the carrier’s residence-only filing duty.

The federal rule, in one sentence

No part of the compensation paid by a motor carrier providing transportation subject to jurisdiction under subchapter I of chapter 135, or by a motor private carrier, to an employee who performs regularly assigned duties in 2 or more States as such an employee with respect to a motor vehicle is subject to the income tax laws of any State or subdivision of that State other than the State or subdivision of the employee's residence. The citation is 49 U.S.C. 14503(a)(1). In plain terms: a company driver whose regular routes cross state lines owes state income tax on that pay to the state they live in, and to no other state, no matter how many states the truck passes through.

In subsection (a), the term employee has the meaning given that term in 49 U.S.C. 31132, the commercial motor vehicle safety definitions section. A motor carrier or motor private carrier withholding pay under subsection (a) files income tax information returns and other reports only with the State and subdivision of residence of the employee.So the paperwork follows the same line as the tax: one state, the driver’s residence, on both the withholding and the carrier’s information returns.

Who the rule covers, and who it leaves out

The section speaks only to compensation paid to an employee. It does not address an independent contractor or owner-operator's own business income, a driver whose regularly assigned duties stay in one State, or road and fuel taxes a carrier pays on the vehicle, such as IFTA fuel tax and IRP registration.

Covered: a W-2 driver employed by a motor carrier or a motor private carrier, with regularly assigned duties in two or more states. The residence state taxes the pay; the states on the route do not.
Not decided by this rule:an owner-operator’s business income. That tax picture starts with how the business is formed and where it is based, which is the ground covered by forming an LLC for a trucking company and the owner-operator versus company driver comparison.
Not a vehicle tax rule: the fuel tax a carrier settles each quarter through IFTA filing and the apportioned plate fees behind IRP registration keep running on miles and weight, exactly as before. Residence-state wage tax and per-mile road taxes answer different questions.

What a driver should check on the next pay stub

The state withholding on the stub should be the state of residence. A second state withholding from a state the route only passes through is the error this statute exists to prevent.
If the carrier’s terminal state is withholding instead, show payroll the citation: 49 U.S.C. 14503(a)(1) for the tax, and 14503(c) for where the carrier files its information returns.

This page records the federal rule and its limits, checked 2026-11-02 against the U.S. Code as published by the Government Publishing Office. It does not record any state’s rate, bracket or filing threshold, and it is not tax advice for a specific return. A driver whose carrier withholds in the wrong state after being shown the citation has a payroll correction to request, and a state return question a tax preparer can settle with the statute in hand.
