Certificates of Exemption

Exempt Certificate for Non-profit, Charitable, School, Religious, or Government Organizations 

Issued by the Colorado Department of Revenue. An organization should first obtain income tax exempt status 501(c) (3) from the Internal Revenue Service (IRS) if necessary. To apply for this certificate with Colorado, use the Application for Sales Tax Exemption for Colorado Organization (DR 0715). No fee is required for this exemption certificate and it does not expire. All valid non-profit state exemption certificates start with the numbers 98 or 098. 

Exempt License for Contractors 

Used only for purchasing construction and building materials for tax-exempt organization projects. This license is issued only to the General Contractor. Sub-contractors must obtain a copy of the certificate from the General Contractor. For contractors who do not need a sales tax license, trade name registration and renewal are handled by the Colorado Secretary of State Business Center. To receive an exemption certificate for construction contracts with tax exempt organizations use the Contractor Application for Exemption Certificate (DR 0172). No fee is required for this exemption certificate. Blanket certificates will not be issued for continuous building maintenance and other non-construction projects.
