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. 


Close Sales Tax Account

This page explains how to close your sales tax account if your business ceases operations entirely. If you are just closing a location (site), visit the Close Locations in Your Sales Tax Account page for information and instructions. 

When you need to close a business, ensure the business closes in good standing with the Colorado Department of Revenue. Any taxes the business is expected to remit must be paid or returns with "zero" tax due must be filed if your business did not have any retail sales that are subject to tax.

The Department of Revenue must be notified on the final return that the business is closing. Be sure to include the effective date of closure (the last day of business). If you do not file and remit payment for business, the Department will mail a non-filer notice to you. The closure request should be submitted no later than 30 days after closing your business.

You can close your sales tax account using Revenue Online or by filing the Business Account Closure Form (DR 1108). When using a paper form, send the completed form to the address on the form. Please note that the paper DR 1108 takes longer to process. Revenue Online closures are effective the next business day.
