Change Sales Tax Account Address

Sales tax license mailing address changes may be completed through Revenue Online or with the Address Change or Business Closure (DR 1102). Physical location address changes cannot be done in Revenue Online because the change may impact the tax jurisdiction, sales tax rates and the Department wants to ensure the proper jurisdictions are included for the business location or site.

For physical address location/site changes, write to

Colorado Department of Revenue
Sales Tax Section #208
PO Box 17087
Denver, CO 80217-0087

or send an email request to dor_multilocations@state.co.us and include the ​12-digit​ Colorado ​Account Number (CAN), final date business was transacted within that jurisdiction or the location address change effective date and the name and contact information of the person requesting the address change.
