Change Sales Tax Account Address

Sales tax license mailing address changes may be completed through Revenue Online or with the Address Change Form (DR 1102).

Physical location address changes cannot be done in Revenue Online, because the change may impact the tax jurisdiction and sales tax rates, so the Department wants to ensure the proper jurisdictions are included for the business location or site.

For physical address location/site changes, send an email request to dor_taxapplications@state.co.us or send a completed Address Change Form (DR 1102) via USPS First Class mail to the following address.

Colorado Department of Revenue
Taxpayer Service Center
PO Box 17087
Denver, CO 80217-0087

Be sure to include your 12-digit Colorado Account Number (CAN), the location address change effective date, and your name and contact information.
