Colorado taxes through the Colorado Department of Revenue at a 2.9% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales. Filing runs monthly, quarterly, or annually by liability. Because Colorado runs an annual bracket, low-volume medical and dental practices can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
Employer registration runs through the Colorado Department of Labor and Employment, and the entity is registered with the Colorado Secretary of State. Home-rule cities administer their own sales tax separately from the state. The Sales and Use Tax System (SUTS) consolidates filing, but registration is still per-jurisdiction.

Registering to do business in Colorado
Registering to do business in Colorado runs through the Colorado Secretary of State, with tax accounts through the Colorado Department of Revenue and employer accounts through the Colorado Department of Labor and Employment. Colorado treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.
Entity-level obligations in Colorado
Beyond sales tax, Colorado entities carry their own obligations — registration with the Colorado Secretary of State, and whatever annual entity-level tax or report the state imposes to stay in good standing. Home-rule cities administer their own sales tax separately from the state. The Sales and Use Tax System (SUTS) consolidates filing, but registration is still per-jurisdiction. Losing good standing is not merely administrative: it can interrupt financing, a sale, or a license renewal at the worst possible moment, which is why these are accrued and calendared rather than discovered.
Are your services taxable in Colorado?
Whether medical and dental practices services are taxable in Colorado is the question that catches people out — states differ enormously, and several have been broadening what counts. Home-rule cities administer their own sales tax separately from the state. The Sales and Use Tax System (SUTS) consolidates filing, but registration is still per-jurisdiction. We code service revenue separately from any product revenue so the treatment is explicit rather than assumed.
