Workshops, Courses, Tools and Resources to help you master Colorado sales tax
Colorado sales tax compliance is uniquely complex, with state, county, and dozens of self-collecting home-rule jurisdictions each maintaining separate rules, rates, and filing requirements. CO Sales Tax Academy provides courses focused specifically on Colorado sales and use tax, developed for business owners, bookkeepers, and tax professionals who need practical, applicable knowledge.
Course topics include nexus determination, registration requirements, taxability and exemptions, tax collection procedures, filing and remittance across jurisdictions, and the use of state and local filing portals, including SUTS and Revenue Online. Instruction is grounded in Colorado's specific regulatory framework rather than general sales tax principles.
