File Utah Form TC-40S
Prepare Utah Form TC-40S now with TaxAct
Form TC-40S is the form needed by any Utah resident that works in another state to avoid dual taxation on income earned in other states. The reason that an Utah resident that works in another state would face dual taxation on income they earned in other states if they failed to file Form TC-40S is that their income would be taxed by both Utah (the state of residence) and the other state (where the income was earned). Form TC-40S is a supplemental form and should be filed with Form-TC40.
