Does an interstate truck driver who lives in Wyoming but is dispatched from a Utah terminal owe Utah state income tax on wages earned driving through Utah?

Plain-English summary

A truck driver who lives in Wyoming, but is dispatched from his employer's Salt Lake City, Utah terminal, asked whether he owed Utah income tax. He drives roughly 5,700 miles a week across Wyoming, Utah, Nebraska, Missouri, Iowa, Minnesota, and Tennessee, and only about 350 of those weekly miles — roughly 6% of his pay — are for driving on Utah highways. He receives no government services from Utah and has no other connection to the state.

The Utah State Tax Commission ruled, assuming he is truly a Wyoming domiciliary with no Utah domicile, that he owes no Utah income tax on these wages. The controlling rule is federal, not state: under (then) 49 U.S.C. § 14053 — a federal statute governing interstate motor carrier employees — wages earned operating in interstate commerce are taxable only in the employee's state of domicile, regardless of how many states the truck actually crosses or how the pay is allocated among them. Utah defines "domicile" as an individual's true, fixed, permanent home or place of permanent and voluntary habitation — being dispatched from a Utah terminal doesn't make Utah your domicile if your actual home is elsewhere.

Because he's not domiciled in Utah, his employer isn't required to withhold Utah tax from his wages at all. To stop withholding, he needs to give his employer a withholding exemption certificate certifying he had no Utah tax liability last year and doesn't expect any this year. If Utah tax was already withheld in error, he can get it back by filing a Utah nonresident return (Form TC-40NR).

What this means for you

Interstate truck drivers dispatched from a Utah terminal but living elsewhere

Being dispatched from, or regularly driving through, Utah does not by itself create Utah income tax liability. What matters is your legal domicile — your true, fixed, permanent home. If that's not Utah, your wages from interstate driving aren't taxable here under federal law, no matter how the miles or pay are allocated among states.

Trucking companies handling multi-state driver payroll

If a driver is domiciled outside Utah, you're not required to withhold Utah tax on their wages — but you do need a signed withholding exemption certificate from the driver on file to stop withholding, and should be prepared to correct withholding going forward once you have it.

Drivers who had Utah tax wrongly withheld

You're not without a remedy — file a Utah nonresident return (TC-40NR) to claim a refund of any Utah tax mistakenly withheld from wages that are actually taxable only in your home state.

Common questions

Q: I'm dispatched from a Utah terminal but I live in another state — do I owe Utah income tax?
A: Not under this ruling's reasoning, as long as you're truly domiciled outside Utah. Federal law taxes interstate trucking wages only in the driver's state of domicile, not the dispatch state or the states the route passes through.

Q: My employer has been withholding Utah tax from my paycheck even though I don't live in Utah. What do I do?
A: Give your employer a withholding exemption certificate confirming you had no Utah tax liability last year and don't expect any this year, so withholding stops going forward. For tax already withheld, file a Utah nonresident return (TC-40NR) to claim a refund.

Q: Does it matter what percentage of my miles or pay comes from driving in Utah?
A: No — the federal rule this ruling relies on doesn't apportion tax by miles or pay across states for interstate trucking employees; it assigns all the tax to the single state of domicile.

RE:
State Income Tax withheld on "over the road drivers."

Dear
XXXXX:

I
am employed as an "over the road truck driver" by XXXXX whose home
office is XXXXX. The correspondence probably should be directed at the payroll
Dept.

I
am a resident of Wyoming who is employed by XXXXX of XXXXX. XXXXX has a
terminal in Salt Lake City Utah, which is the home terminal I am dispatched
from. I normally drive and sleep in a truck that runs approximately 5700 miles
a week. Out of that 5700 miles we are on Utah highways and are paid for
approximately 350 of the 5700 miles a week for the 350 miles we drive in Utah.
The question I have is, am I required to pay state income tax when I only
receive approximately .06% of my income for driving in Utah, and the other
miles I am paid for are in Wyoming, Nebraska, Missouri, Iowa, Minnesota, and
Tennessee? Also, I receive no services from Utah, nor do I have any
representation in Utah. Would you please send myself and XXXXX's payroll Dept.
an opinion on this matter.

Thank you,

XXXXX

Advisory Opinion - Non-resident income tax

Dear XXXXX

We
have received your request regarding Utah income tax. On the basis of the information presented in your letter, we
assume for purposes of this response that you are a resident of Wyoming and
that you do not maintain a domicile in Utah that subjects you to Utah income
tax. On that basis we find as
follows:

As
an over the road driver operating in interstate commerce, your income is
taxable in your state of domicile. �49
U.S.C. 14053 (copy enclosed). From
Utah�s perspective, �domicile� means the place where an individual has a true,
fixed, permanent home or place of permanent and voluntary habitation.

If
you are not domiciled in Utah, your employer is not required to deduct and
withhold Utah tax on your wages. You
must furnish your employer a withholding exemption certificate certifying that
you incurred no Utah tax liability for the preceding tax year, and you do not
anticipate incurring Utah tax liability during the current tax year. If your employer incorrectly withheld and
reported your income in Utah, you may claim a refund by filing a nonresident tax
return (TC-40NR).

Please
let us know if we can be of further assistance.

For
the Commission,

Alice
Shearer,

Commissioner
