What to do

Frequently asked questions

Do I pay Utah income tax if I live in Colorado?

Yes. Utah taxes wages earned there by nonresidents. On $100,000 that's about $4,450.

Do I have to file taxes in both Colorado and Utah?

Usually yes: a nonresident return in Utah and a resident return in Colorado, where you claim a credit for the tax paid to Utah. File the Utah return first.

Will I be taxed twice?

Not on the same state-level wages. Colorado credits the tax you pay Utah, so your total is about $4,450 on $100,000, compared with $3,692 if you also worked in Colorado. Local city or county taxes may still apply.
