What Colorado Counties License and What They Leave to Cities: Zoning, Short-Term Rentals, Cannabis and Sales Tax
What Colorado Counties License and What They Leave to Cities: Zoning, Short-Term Rentals, Cannabis and Sales Tax
If you searched for a colorado county business license, here is the short answer: Colorado has no general state business license, and counties do not appear to issue one either. What a business needs depends on its entity, its tax obligations and its activity. A new business forms its entity with the Secretary of State, opens a Department of Revenue account if it collects or withholds tax, then adds the licenses and permits for its activity from the state, its city or its county.
Counties matter most in three places: unincorporated land, where the county writes zoning and building rules; county sales tax, which is collected on the state return; and a few decisions that county commissioners make directly, such as short-term rentals, liquor and cannabis. Most Colorado businesses sit inside a city, and for them the city handles most of the rest. This guide explains what each level does so you know which office to call.
Is There a Colorado County Business License?
No general one. Counties do not issue a business license that covers ordinary operations, so no county permit makes a business legal on its own. Instead, county government meets your business in specific areas: land use, property tax reporting, certain tax collections and a few regulated activities. If your business operates inside a city, the city handles those areas instead, and some cities add their own licenses on top of state requirements. Before you assume a county requirement applies, confirm it with the county clerk, planning department or building department that serves your address.
Start With the State
Every business begins with the Colorado Secretary of State, Business Organizations Division (https://www.coloradosos.gov/pubs/business/businessHome.html). These state items apply to nearly every new entity:
- Entity formation: An LLC files Articles of Organization for a Limited Liability Company for a $50 filing fee. A corporation files Articles of Incorporation for a Profit Corporation for the same $50. Most documents are filed through the online system at https://www.coloradosos.gov/pubs/business/fileAForm.html, which processes filings in real time after payment.
- Name reservation: $25 reserves a name for 120 days.
- Registered agent: Every entity must name one, and the agent must consent. An individual agent must be at least 18, hold a current Colorado driver's license or state ID card, and either live in Colorado or have a usual place of business there. Enter the agent's name and ID number exactly as they appear on the credential. Without Colorado ID, the agent can request a passcode from the Secretary of State, which expires 45 days after it is issued. The address must be a physical Colorado street address where documents can be received during business hours, never a P.O. box.
- Periodic report: $25 each year. A new LLC or corporation files no periodic report in its first year, and the first report is due in the second year. You may file from two months before to two months after the periodic report month shown on your record without penalty. An entity that does not file becomes Delinquent.
- Trade names: A Statement of Trade Name is filed statewide with the Secretary of State, not the county. It costs $20 to file online and $5 to renew.
For taxes, the Department of Revenue's Taxation Division administers sales and use, withholding and income taxes (https://tax.colorado.gov/). Colorado has no franchise tax. Corporations pay a flat 4.40% corporate income tax, and LLC income passes through to the owners and is subject to the same flat 4.40% state income tax. The only recurring Secretary of State cost is the $25 periodic report.
What Counties Handle
Zoning and Building Permits in Unincorporated Areas
Counties control land use outside city limits. If your shop, storage yard or home office sits in unincorporated territory, county zoning determines what you can do on that property, and the county building department issues permits for construction, remodeling and changes of use. Inside a city, the city does both jobs. Ask the county planning or building department about zoning before you sign a lease or buy property, because a use allowed in one zone may not be allowed in another. Fees and review times vary, so confirm current figures with that office.
County Sales Tax
Where a county levies its own sales tax, it is collected through the Colorado sales tax return you file with the Department of Revenue. Denver and Broomfield are consolidated city-counties, so this guide has no county page for them. Rates differ by location, so confirm the current rate for your address on the state's SUTS Jurisdictions page (https://tax.colorado.gov/SUTS-Jurisdictions).
Business Personal Property Declaration
Each county assessor receives an annual declaration of business personal property, due April 15. It covers business equipment, furniture and similar tangible property. For tax years 2025 and 2026, a business is exempt when its total actual value of business personal property is $56,000 or less in a county, under C.R.S. 39-3-119.5. Because this figure is confirmed only for those two years, check with your county assessor before relying on it for later years. Our business personal property tax guide covers the filing process in more detail.
Short-Term Rentals
Under C.R.S. 30-15-401(1)(s), county commissioners may license short-term rentals, which Colorado defines as a rental under 30 days. In unincorporated areas, the county sets those rules. Inside a city, the city sets them. Rules differ widely, so confirm with the county commissioners' office or planning department before you list a property. Our short-term rental rules by city and county page compares specific jurisdictions.
Liquor and Cannabis Outside City Limits
County commissioners hold local authority over liquor licensing in unincorporated areas under C.R.S. 44-3-301, and over marijuana licensing under C.R.S. 44-10-104. The state still issues its own licenses through its Liquor Enforcement Division and Marijuana Enforcement Division, so expect to deal with both the state and the local authority. Ask the county clerk which office takes applications and what local steps apply, since those steps are set by the county and not by this guide.
Unincorporated areas can also work differently from what you expect. Highlands Ranch, for example, is unincorporated Douglas County and is run by a metro district rather than a city. No city license sits behind it, so county rules and district requirements are the ones to check.
What Cities Handle
A city's authority covers everything inside its limits. Three points matter most:
- Home-rule cities collect their own sales tax. Denver, Aurora, Colorado Springs, Boulder and Fort Collins are examples. They collect and license their own city sales tax, so the state sales tax license does not cover them. A business in one of those cities must apply to the city directly.
- Contractor licensing. Colorado does not license general contractors, roofers, HVAC contractors, handymen or home inspectors at the state level. Cities and counties, through their building departments, do. Electricians and plumbers are licensed by DORA, the Department of Regulatory Agencies' Division of Professions and Occupations. Check with your city or county building department for its contractor requirements.
- Zoning and short-term rentals. Inside city limits, the city controls land use, building permits and short-term rental rules.
Sales Tax: The State Return Does Not Cover Everything
The state sales tax rate is 2.9%, plus any special district taxes that apply to your location. Most sellers of tangible goods need a Colorado sales tax license from the Department of Revenue (https://tax.colorado.gov/how-to-apply-for-a-colorado-sales-tax-license). That license covers the state and the jurisdictions the state collects for. It does not cover home-rule cities, which license and collect separately. Services are generally not subject to the state sales tax, but confirm treatment for your specific services with the Department of Revenue.
County Sales Tax by County
Colorado has 64 counties. About 50 appear on the state's SUTS Jurisdictions page with county sales taxes. Weld is not on that list, so it has no county sales tax. The table covers the 11 counties with dedicated pages on this site and three counties without one. Confirm each rate on the SUTS page or with the Department of Revenue before you set prices.

| Mesa | No | County sales tax, plus Mesa County improvement district and public safety taxes | Check with Mesa County for short-term rental rules, and with the county building department for contractor licensing in Grand Junction. |
