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. 


DR 8454 - Income Tax Declaration for Online Electronic Filing


If electronically filing more than one return for a taxpayer or entity/business, a separate DR 8454 is required for each qualifying entity. By participating in the electronic filing option, the PC online filer agrees to maintain this form (DR 8454) for four years from the due date of the return or the date the return was filed, whichever is later. The PC online filer also agrees to present this form upon request to the Department of Revenue at any time during the four-year period.

DO NOT MAIL THIS FORM TO THE IRS OR THE COLORADO DEPARTMENT OF REVENUE unless you receive a request from the Colorado Department of Revenue for this document.
