Most licenses are valid for a two-year period and expire at the end of each odd-numbered year. All licenses must be displayed at a business location and may not be used to obtain personal goods or business assets tax-free.

If your address has changed, please verify and correct it through Revenue Online. This way, your new license will be delivered to the correct address.

To Register:

Apply for a sales tax license using Colorado Business Express or fill out and submit the Sales Tax / Wage Withholding Account Application (CR 0100).  Once complete, you can mail the form to us or take it to any Taxpayer Service Center. The Colorado Department of Revenue requires all new businesses to show a picture ID for all registrations at the walk-in service district offices. 

Cash is not accepted. All fees or tax payments must be paid by check or money order.
 If you wish to pay in cash, you may do so at 1881 Pierce Street, Lakewood, 80214. However, taxpayer assistance is not available at the Pierce location.
