Colorado business licensing guide
Last checked: April 26, 2026
Colorado does not handle business licensing as one simple statewide license for every business. Most owners need to put together the right mix of state registration, Colorado tax accounts, local city or county licenses, zoning approval, and industry permits.
This guide explains the Colorado pieces in plain English and shows where to verify each step with the official agency.
The short answer
In Colorado, start by identifying your business structure, business name, location, products or services, and whether you will hire workers. Then check these layers: Colorado Secretary of State filing, Colorado Department of Revenue tax accounts, city or county licensing, zoning, and any professional or industry license.
The Colorado Secretary of State says that after filing a business, owners may still need to research federal, state, county, and local licensing requirements. Some licenses are handled by the Colorado Department of Regulatory Agencies, while others are handled by city or county offices.
Quick start for Colorado businesses
Use this order if you are just getting started.
- Write down your business activity, address or service area, business structure, and whether you will sell taxable goods or hire workers.
- Search the Colorado Secretary of State business database and decide whether you need to file an entity, a trade name, or both.
- If you sell retail goods in Colorado, check whether you need a Colorado sales tax license from the Colorado Department of Revenue.
- Use the Colorado sales tax lookup and check whether your city is a home-rule city that has its own local tax license or filing system.
- Contact your city or county about zoning, business licensing, home occupation rules, building permits, signage, and certificate of occupancy issues.
- Check state industry licensing if your work involves regulated fields such as food, alcohol, marijuana, child care, health care, electrical work, plumbing, real estate, insurance, pesticides, or pet animal facilities.
- If you will hire workers, set up the federal and Colorado employer accounts before your first payroll.

| Sales tax license | The Colorado sales tax license is for state and state-administered sales and use taxes. It is not the same thing as a general business registration. | Colorado sales tax license |
| Home-rule cities | Some Colorado cities collect their own local sales tax and may require a local sales tax license. A state sales tax license may not cover those local requirements. | CDOR location and home-rule guidance |
| Professional and industry licenses | DORA and other state agencies regulate many professions and business activities. Local permits may still apply. | Colorado DORA licensing and permitting |
Colorado business licensing is layered
Do not look for one form that makes the whole business legal. In Colorado, each government layer handles a different part.
| Government layer | What it may control | Colorado examples |
|---|---|---|
| Federal | Federal tax ID, federal permits for federally regulated activities, and certain federal reporting rules. | IRS EIN, SBA federal permit categories, alcohol, firearms, aviation, transportation, broadcasting, or agriculture-related federal rules when applicable. |
| State of Colorado | Entity filings, trade names, state tax accounts, unemployment accounts, workers’ compensation rules, professional licenses, and industry permits. | Colorado Secretary of State, Colorado Department of Revenue, CDLE, DORA, CDPHE, Department of Agriculture, and Specialized Business Group. |
| County | Public health, building, land use, unincorporated-area zoning, short-term rental rules, and local permits. | County public health agencies for many food businesses; county planning and zoning for unincorporated locations. |
| City or town | Local business license, city sales tax license, zoning approval, home occupation permit, sign permit, fire review, building permits, and certificate of occupancy. | Denver business licenses by activity, Aurora business license, Boulder city business license, Colorado Springs local sales tax and licensing, Pueblo business license. |
| Private platform | Marketplace rules, payment processor rules, delivery app onboarding, insurance, and seller verification. | Etsy, Shopify, Amazon, DoorDash, Airbnb, or payment platforms may ask for tax or business information, but they do not replace government licenses. |
Important: A Colorado LLC filing is not a business license. A Colorado sales tax license is not a zoning approval. A local business license is not a professional license. Check each layer separately.
Step 1: Register the business with the Colorado Secretary of State if needed
The Colorado Secretary of State handles business entity records. This includes many LLCs, corporations, nonprofits, partnerships, foreign entities, and trade names.
You can search business names, file a form to create a new record, file a form for an existing record, and validate certificates through the Secretary of State business services pages. The state also lists MyBizColorado as an official filing tool for the State of Colorado.
When this applies
- You are forming a Colorado LLC, corporation, nonprofit, limited partnership, or other filing entity.
- You are a foreign entity that needs authority to transact business in Colorado.
- You are a sole proprietor or general partnership using a trade name.
- You need to update, maintain, or file periodic reports for an existing Colorado business record.
What this does not do
A Secretary of State filing creates or maintains a state business record. It does not automatically give zoning approval, a city business license, a sales tax account, a health permit, a liquor license, or a professional license.
Trade names and DBAs in Colorado
Colorado uses the term “trade name” for many DBA-style filings. The Secretary of State says a for-profit business not using the entity’s true name, or an individual not using their legal first and last name to conduct business in Colorado, is required to file a trade name.
For example, if Maria Lopez runs a sole proprietorship as “Front Range Mobile Notary,” the trade name issue is separate from whether she also needs a city license, tax account, or professional registration.
Practical tip: Search the Colorado Secretary of State database before using a business name. Also check domain names, trademarks, and local license records if the name will be public-facing.
Trade name filing is not the same as trademark protection
A Colorado trade name filing creates a state record. It does not automatically give federal trademark rights. If the name is important to your brand, check the Colorado Secretary of State trademark information and the U.S. Patent and Trademark Office.
Step 2: Check Colorado tax accounts and sales tax licensing
Colorado tax setup is one of the most important parts of this process. The name of the account depends on what your business does.
| Colorado item | Plain-English meaning | Who may need it | Official starting point |
|---|---|---|---|
| Colorado sales tax license | A state sales tax account or license for state and state-administered sales and use taxes. | Businesses making retail sales in Colorado. The Department of Revenue says tangible personal property is generally subject to sales and use tax, while services are generally not subject to sales tax. | How to apply for a Colorado sales tax license |
| Standard Retail License | The common Colorado sales tax license for businesses that make retail sales. CDOR says it can cover both retail and wholesale sales if the business makes both. | Retailers with one or more Colorado locations or sales activity that creates a Colorado filing requirement. | Standard Retail License |
| CR 0100 | Colorado Sales Tax and Withholding Account Application. | Businesses opening a sales tax account, wage withholding account, or adding certain new physical locations. | Form CR 0100 |
| Revenue Online | Colorado Department of Revenue online tax account system. | Businesses managing Colorado state tax accounts. | Colorado Department of Revenue Taxation |
| SUTS | Colorado Sales and Use Tax System. It lets businesses file retail sales tax returns for state, state-collected, and participating home-rule self-collecting jurisdictions in one place. | Retailers that need to file Colorado sales and use tax returns in participating jurisdictions. | Sales and Use Tax System |
| GIS sales tax lookup | Address-based lookup for sales tax rates and jurisdictions. | Businesses that need to confirm the correct sales tax rate for a location, delivery address, city, county, or special district. | Colorado GIS sales tax information |
Colorado sales tax license fees and deposit
As of the last check for this guide, the Colorado Department of Revenue listed Standard Retail License fees that vary by when the license is applied for in the two-year cycle. CDOR also listed a $50 sales tax deposit for new accounts, refundable after the business collects and pays $50 in state sales taxes. Always confirm the current fee and deposit on the official CDOR page before applying.
Home-rule cities can change the tax picture
Colorado’s home-rule city system is a common source of mistakes. CDOR says state sales tax licenses cover state and state-collected tax jurisdictions only. If you are in a home-rule city, contact that city for its license requirements.
CDOR also says home-rule cities must be contacted directly when sales are made within their jurisdictions and that they require businesses to have a local sales tax license. Some home-rule cities participate in SUTS. Others may still have their own city filing portal.
Do not assume the state account covers the city. Use the Colorado GIS lookup, then check the city’s own tax or licensing page for the exact location where you operate, deliver, store inventory, host events, or make sales.
Step 3: If you hire workers, set up employer accounts
Hiring employees adds a separate set of requirements. Handle these before payroll starts.
- Federal EIN: The IRS says businesses generally need an EIN to hire employees, operate a partnership or corporation, pay certain taxes, or change business structures. Get it directly from the IRS.
- Colorado wage withholding: If you must withhold Colorado income tax, CDOR says you must apply as a withholding tax agent. This is a Colorado wage withholding tax account, not a general business registration.
- Unemployment insurance: CDLE says employers paying wages to at least one employee in Colorado may need to register for an unemployment account. Colorado uses MyUI Employer+ for UI employer account management.
- Workers’ compensation: CDLE says all businesses with employees operating in Colorado must have workers’ compensation insurance, with limited exceptions.
- New hire reporting: Colorado uses a New Hire Reporting Employer Services Portal for reporting new hires and rehires.
- FAMLI: Colorado’s paid family and medical leave program may create employer payroll obligations. Check CDLE and the My FAMLI+ Employer portal if you have employees.
Practical order: Get the EIN first, then check Colorado wage withholding, UI, workers’ compensation, new hire reporting, and FAMLI before issuing the first paycheck.
Step 4: Check city, county, zoning, and home-based rules
Local rules are often the step that trips people up in Colorado. A state filing may be complete, but the city or county may still control whether your business can operate at a specific address.
If you have a storefront, office, warehouse, salon, studio, or restaurant
Before signing a lease, ask the city or county planning office whether your use is allowed at that address. You may also need building permits, fire review, a sign permit, a certificate of occupancy, or a local business license.
If you run the business from home
Home-based businesses usually need a zoning check. Denver says home occupations are intended to be secondary to the home’s main use as a dwelling and may be limited by size, employees, signage, and hours. Colorado Springs has a Home Occupation Permit process and tells applicants to check building, fire, and sales tax issues before applying. County rules may apply if the address is outside city limits.
If you sell food
Food businesses often involve both state and local review. CDPHE says it licenses and inspects restaurants, mobile food units, and grocery or convenience stores only in certain counties. In other counties, contact the local public health agency. Cottage food businesses should check Colorado’s Cottage Foods Act and any local rules before selling.
If you operate online only
An online business may still need Colorado tax registration, a trade name, local zoning approval for a home office, or local licensing if inventory, employees, pickups, deliveries, or regulated services are tied to a Colorado location.
Step 5: Check industry-specific Colorado licenses
Some Colorado businesses need a state license or permit because of the work they do. This is separate from entity filing and local licensing.
Professional and occupational licenses
DORA and the Division of Professions and Occupations regulate many professions and business credential types, including fields such as accountancy, architecture, barber and cosmetology, electrical, plumbing, landscape architecture, outfitting, and radon professionals.
Food businesses
CDPHE and local public health agencies handle retail food, mobile food, manufactured food, and cottage food issues depending on business type and county.
Liquor and tobacco
Colorado liquor licensing is a dual state and local process for many retail applicants. The state says retail liquor applicants generally need local approval first.
Marijuana businesses
Colorado marijuana businesses need state and local approvals. State application materials warn that a business cannot operate before obtaining all necessary approvals or licenses from both the State Licensing Authority and the local jurisdiction.
Agriculture, pesticides, and pet facilities
The Colorado Department of Agriculture handles licensing programs such as commercial pesticide applicator business licensing and Pet Animal Care and Facility Act licensing.
Child care and health facilities
Child care and health facility businesses may need state licensing and health inspections. CDPHE says an approving health inspection is required before certain child care licenses can be issued.
Check before advertising or taking clients. For regulated work, licensing can apply to the business, the individual professional, the location, or all three.
Colorado city links and local starting points
Local licensing varies by city. Start with the official city page for your address. If a BusinessLicenseGuide city guide already exists, it is included here as a plain-English next step.
| City | BusinessLicenseGuide city guide | Official local starting point | Why it matters |

Common mistakes in Colorado
- Thinking an LLC is the license. An LLC filing is a business record. It does not replace local, tax, zoning, or industry permits.
- Ignoring home-rule cities. A Colorado state sales tax license may not cover a home-rule city’s local license or filing rules.
- Signing a lease before checking zoning. A landlord may rent the space, but the city or county may not allow your use there.
- Using a trade name without filing it. Colorado uses trade name filings for many DBA situations.
- Calling every requirement a business license. A sales tax license, home occupation permit, food license, liquor license, and professional license are different things.
- Skipping county health review for food. CDPHE handles retail food licensing only in some counties. Many food businesses must contact the local public health agency.
- Hiring before employer setup is complete. EIN, wage withholding, unemployment, workers’ compensation, new hire reporting, and FAMLI should be checked before payroll.
- Assuming online means no local rules. Home offices, inventory storage, local deliveries, pickup, signs, and employees can all create local requirements.
What to ask when you contact the agency
Before calling or emailing, have your business details ready. Include your business type, Colorado city or county, address or general location, whether it is home-based, mobile, online, storefront, or delivery-based, what you sell or do, and whether you will have employees.
Phone or email script
Hello. I am starting a [business type] in [city], [county], Colorado. The business will be [home-based / mobile / storefront / online] at [address or general location]. I plan to [briefly describe products or services]. Can you confirm whether I need a local business license, sales tax license, zoning approval, home occupation permit, certificate of occupancy, health permit, building or fire review, or another permit before I start? If your office does not handle this, which office should I contact next?
If you are contacting a state agency, change the question to ask about the specific state account or license. For example, ask CDOR about sales tax or withholding, DORA about a professional license, CDPHE or the local public health agency about food, and CDLE about employer accounts.
- Write down the agency name and the person or department that answered.
- Write down the date of the call or email.
- Ask for the exact license, permit, account, or approval name.
- Ask whether the requirement is state, county, city, or federal.
- Ask for the official application link and current fee page.
- Ask whether zoning must be approved before filing the license application.
- Ask whether renewal, posting, inspection, or recordkeeping rules apply.
- Save the answer with your business records.
If you only do one thing today
Find the exact address where the business will operate, then check the Colorado Secretary of State, Colorado Department of Revenue, and the city or county for that address. In Colorado, the address can decide whether a home-rule city license, local sales tax license, zoning permit, or health department review applies.

FAQ
Does Colorado have one statewide general business license?
No. Colorado does not use one single state license for every business. Most businesses need to check state registration, Colorado tax accounts, local city or county licensing, zoning, and any industry-specific license.
Is forming an LLC the same as getting a Colorado business license?
No. An LLC filing creates a business entity record with the Colorado Secretary of State. It does not replace a sales tax license, local business license, zoning approval, health permit, professional license, or employer account.
What does Colorado call a DBA?
Colorado commonly uses the term trade name. A for-profit business using a name other than its true name, or an individual using a name other than legal first and last name, may need to file a trade name with the Colorado Secretary of State.
Do I need a Colorado sales tax license?
You may need a Colorado sales tax license if you make retail sales in Colorado. The Colorado Department of Revenue says the license is for state and state-administered sales and use taxes. Home-rule city requirements may still apply separately.
What is a Colorado home-rule city?
A home-rule city may administer its own local sales tax and licensing rules. If you operate or make sales in a home-rule city, check the city directly even if you already have a Colorado state sales tax license.
Can I run a business from home in Colorado?
Maybe. Home-based business rules are usually local. Your city or county may require zoning approval, a home occupation permit, limits on signs or customer visits, and other approvals before you use your home address for business.
Who handles professional licenses in Colorado?
Many professional and occupational licenses are handled by the Colorado Department of Regulatory Agencies and the Division of Professions and Occupations. Other industries may be handled by CDPHE, the Department of Revenue, the Department of Agriculture, CDLE, or local agencies.
Do online businesses need a Colorado business license?
They might. An online business may still need a Colorado sales tax account, trade name filing, local zoning approval for a home office, employer accounts, or a local license depending on the business activity, address, inventory, employees, and customers.
