I live in Ohio but I drive cross country as a driver. My company offices are in Nebraska, WI and AZ. How do I do non-resident state taxes?

You would just file a return for your resident state of Ohio on the truck driving income.

You are covered under the Amtrak Act.  In 1990, Congress passed the Amtrak Act. The short version is that interstate truckers owe state and local income taxes to their home states and localities- nowhere else.

Now if they took taxes out then file a non-resident return for that state with $0 income and get the money back that was paid in if on the W-2.
