What to expect and how to prepare for this year's tax season

Colorado Cash Back 2022
To receive your Colorado Cash Back Check, you must file your Colorado state income tax return or apply for a property tax, rent, or heat credit rebate (commonly known as the PTC Rebate) by June 30, 2022. You'll then receive Colorado Cash Back by September 30, 2022. Extended filers who have a deadline of October 17, 2022, will receive the refund by January 31, 2023.  The Internal Revenue Service (IRS) has determined that it will not require Coloradans to pay federal income tax on these expedited tax refunds.
