Live in Colorado, Work in Utah: Which State Taxes Your Paycheck?
Answer
Two returns, one credit. Utah has the first claim on wages earned inside the state and withholds accordingly. Colorado then taxes you as a resident on everything and gives credit for what Utah already took, capped at what Colorado would have charged on that same income.

Two states can lawfully tax the same wages: Utah because the work happened there, Colorado because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Colorado return, through the credit for taxes paid to another state.
A Colorado resident taxed by another state on the same income claims the credit for taxes paid to other states on Form DR 0104CR. The credit is capped at the Colorado tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
What you file
- 1Nonresident return · UtahForm TC-40 with Schedule TC-40B
File the Utah nonresident return FIRST — you need the Utah tax figure before you can complete Colorado.
- 2Resident return · ColoradoForm DR 0104CR
File a Colorado resident return reporting all income, then claim the credit for tax paid to Utah. The credit is capped at what Colorado would have charged on that same income, so if Utah taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Colorado and work in Utah. Which state takes the tax out of my paycheck?
Two returns, one credit. Utah has the first claim on wages earned inside the state and withholds accordingly. Colorado then taxes you as a resident on everything and gives credit for what Utah already took, capped at what Colorado would have charged on that same income.
Which state should my employer be withholding for?
Utah. The wages are sourced to Utah, so Utah withholding is correct and there is no Colorado withholding to set up.
Will I end up paying tax twice on the same income?
Not twice over, but you will pay the higher of the two rates. Colorado gives residents a credit for tax paid to Utah on the same income, claimed on Form DR 0104CR. The credit is capped at the Colorado tax on that income, so if Utah taxes it more heavily the excess is not refunded by either state.
