I am a Utah non-resident but received $6500 on a 1099-misc from work done in Utah with no withholding taken, do I need to file a State return in Utah for this?

Yes. You will need to file an UT nonresident state income tax return to report your UT sourced earnings. According to the UT Department of Revenue, you must file a UT nonresident state income tax return if you have income from Utah sources and you must file a federal return.

You will also need to report these earnings on your resident state income tax return (if your resident state has an income tax filing requirement). You will get a state tax credit in your home state (if your home state has a filing requirement) for any UT income that is being taxed in both UT and your home state.

Just follow the TurboTax guide when working on your states (remembering to do your nonresident state return first) and TurboTax will do all the calculations and credits to your resident states return
