Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued. 


Individual Income Tax | Filing Requirements

You must file a Colorado income tax return if during the year you were:

  • A full-year resident of Colorado, or
  • A part-year resident of Colorado with taxable income during that part of the year you were a resident, or
  • A nonresident of Colorado with Colorado source income,


  • You are required to file a federal income tax return, or
  • You have a Colorado income tax liability for the year.

A Colorado resident is a person who has made a home in Colorado, or a person whose intention is to be a Colorado resident. The department will consider, among other things, Colorado voter registration, Colorado vehicle registration, Colorado driver license, school registration, property ownership and residence of spouse or children in determining intention to be a Colorado resident.
