City business license guide
Last updated: April 27, 2026
This guide helps you check the main city, county, Colorado, and federal steps that may apply before you start or run a business in Denver. It is written for regular business owners, not lawyers.
Denver licensing is not one simple form for every business. The Business Licensing Center covers many local business and professional licenses. Denver Treasury handles city business taxes. Community Planning and Development handles zoning, building, and many occupancy questions.
Bottom line
Denver does not have one local license that clearly covers every business. Check three local items first: whether your activity needs a Denver business or occupational license, whether the address is allowed under zoning, and whether you need a Denver tax account. Some businesses also need state registrations, an IRS EIN, health permits, fire permits, contractor licenses, or industry permits.
If you sell taxable goods, rent property, provide lodging, hire workers in Denver, sell food, host short-term rentals, run a mobile business, or open a storefront, do not assume an LLC is enough.
Quick start: what to check first in Denver
- Write down your exact business activity. Denver rules can change by activity. A cleaner, food truck, short-term rental host, tattoo shop, contractor, online seller, and home daycare do not follow the same path.
- Check the Denver license directory. Use Denver’s License directory to see if your business type has a local license page.
- Check zoning before signing a lease. Denver says zoning controls allowed uses, activities, parking, signs, building size, and location. Start with Denver zoning permits if your location, home business, sign, use, or build-out may matter.
- Check Denver taxes. Denver is a home-rule city that collects and administers its own taxes. Start with Denver Business Tax if you sell taxable items, owe use tax, collect lodger’s tax, have employees, hold events, or need a Denver tax account.
- Check Colorado registrations. Use MyBizColorado or the Colorado Secretary of State if you form an LLC, corporation, nonprofit, or trade name. Use Colorado Department of Revenue pages for state sales tax and wage withholding accounts.
- Check federal items. Many businesses need an EIN, federal tax setup, or federal permits for regulated activities. Do this after you know your state and city setup.

City, county, state, and federal layers
Business rules in Denver are layered. A Colorado LLC filing does not approve your Denver address. A zoning permit does not replace a state sales tax license.
| Layer | What it may cover | Where to start |
|---|---|---|
| City | Local licenses, tax accounts, zoning, building, fire, signs, food, rental, and inspection rules. | Start with Denver licensing, Treasury, and Community Planning and Development. |
| County | Denver is both a city and county, so county-style items are usually handled by Denver departments. | Use Denver pages for a Denver address. Outside Denver, check that other city and county. |
| State | Entity filings, trade names, sales tax, withholding, unemployment, workers’ comp, and state licenses. | Use MyBizColorado, the Secretary of State, Revenue, and Labor. |
| Federal | EIN, federal tax accounts, federal permits for regulated industries, and current BOI rules for certain foreign entities. | Use the IRS, SBA, and the correct federal regulator for your industry. |
| Private platform | Marketplace, delivery app, booking site, payment processor, landlord, HOA, and insurance rules. | Read the contract. These rules do not replace government permits. |

Denver city steps
1. Check whether Denver licenses your business type
Denver’s Department of Licensing and Consumer Protection says it issues business and professional licenses for the City and County of Denver, except for motor vehicle and building or development items. It also handles renewals, denials, fees, hearings, and certain regulated industries.
Start with the license directory instead of guessing. If your business type appears there, open that page and follow the Denver instructions for that exact license.
Tip: Search by what you do, not just by your company name. Food, rentals, tobacco, massage, security, and repairs may each have different rules.
2. Check Denver tax accounts
Denver Treasury handles city business taxes, including sales and use tax, lodger’s tax, occupational privilege tax, special event sales tax, telecommunications tax, and other local taxes. Denver is home-rule, so a Colorado state account may not be enough.
Denver’s business tax FAQ says Denver no longer charges a license fee with the biannual Retailer’s Sales, Use, Lodger’s Tax License. Use Denver’s official Business Tax FAQs before copying any rate into invoices or checkout software.
If you have Denver employees, ask about occupational privilege tax. If you buy taxable items for Denver use, ask about consumer use tax. If you rent lodging, ask about lodger’s tax.
3. Check zoning before you spend money
Denver zoning can affect the use of property, parking, signs, allowed activities, and the size and location of structures. That means zoning should be checked before you sign a lease, buy a property, build a counter, install a sign, move equipment in, or invite customers to a home.
Home businesses need extra care. Denver’s home business and home occupation page says some home businesses also need a business license and points users back to the business index. It also gives examples of home occupation categories. For a plain-English overview, see our home occupation permit guide.
4. Check building, occupancy, signs, and fire rules
If you open a storefront, office, salon, restaurant, warehouse, studio, daycare, gym, or other site, ask whether plan review, building permits, inspections, or occupancy rules apply. Denver says permits are required for most construction, alteration, or repair work on private property.
Fire rules may apply to public assembly, hazardous materials, storage, flammables, cooking, marijuana, events, or other regulated processes. Denver Fire says operational permits are generally renewed every year.
Colorado and federal steps for a Denver business
Colorado business filings and trade names
Use the Colorado Secretary of State or MyBizColorado if you form an LLC, corporation, nonprofit, or other entity. A sole proprietor may still need a trade name if using a public name other than the owner’s legal first and last name.
The Colorado Secretary of State says a trade name is an assumed name, sometimes called a DBA or assumed name. It also 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. Check the Colorado trade name FAQ before using a public business name.
Colorado sales tax, withholding, unemployment, and workers’ comp
The Colorado Department of Revenue says the Colorado sales tax license covers state and state-administered sales and use taxes. It also warns home-rule city businesses to contact the city for local requirements. That matters in Denver.
If you sell, rent, or lease tangible personal property, check whether you need a Colorado sales tax license. Also check Denver’s tax account rules. If you want a plain-English comparison, see our guide to a seller’s permit versus a business license.
If you pay workers, check Colorado wage withholding, unemployment insurance, workers’ compensation, and FAMLI duties. Start with the state withholding account page and CDLE employer resources.
Federal items
The IRS says businesses generally need an EIN if they hire employees, operate as a partnership or corporation, pay certain taxes, or change ownership or structure. Use the IRS EIN page directly.
The SBA says business activities regulated by a federal agency may need a federal license or permit. This can matter for alcohol, aviation, firearms, broadcasting, transportation, agriculture, import/export, and other regulated areas. Check the SBA licenses and permits page and the correct federal agency.
BOI reporting rules changed. FinCEN states that, under the March 2025 interim final rule, entities created in the United States and their beneficial owners are exempt from BOI reporting, while certain foreign entities registered to do business in the United States may still have duties. Because this area has changed, check FinCEN’s BOI page before relying on old advice.
Special Denver permits and business types
Food businesses
Food businesses should not stop at a basic business setup. Denver points food businesses to licensing, permitting, plan review, inspections, and food safety rules. Start with Denver food license types.
Denver says food trucks, trailers, and carts that operate in Denver need a retail food establishment-mobile license and cannot operate under another license. Read the official mobile retail food guide. For a broader checklist, see our food truck license guide.
Short-term rentals and residential rentals
Denver has detailed short-term rental rules. Denver says all short-term rentals must have a license, must be the host’s primary residence, and must display the host’s business license number in advertisements. Denver also says hosts must follow rules tied to safety, taxes, zoning, and insurance. Start with Denver’s short-term rental laws before listing a property.
Denver also has residential rental property license rules. If you rent housing in Denver, do not assume the short-term rental page is the only rental rule. Check the residential rental property license page and tax duties.
Contractors and building trades
Contractors should check both licensing and permit rules. Denver’s contractor licensing page says contractor licensing is a two-step process and that a license applicant must hold a supervisor certificate, a state electrical or plumbing license, or employ someone who holds the needed credential before applying for a Denver contractor license. Start with Denver contractor licenses.
Costs you can plan for
Do not plan around one flat Denver business license fee. Your cost depends on your activity, address, tax accounts, inspections, build-out, and state filings. Some costs are private, such as insurance, equipment, or lease changes.
| Possible cost | When it may apply | How to verify |
|---|---|---|
| Denver business or occupational license fee | If your business type appears in Denver’s license directory and the license page lists a fee. | Open the specific license page and confirm the current fee before applying. |
| Denver tax account or tax license | If you need a Denver Retailer’s Sales, Use, Lodger’s Tax License or other city tax account. | Denver says it no longer charges a license fee with the biannual Retailer’s Sales, Use, Lodger’s Tax License, but taxes and other charges may still apply. Confirm with Treasury. |
| Zoning, building, sign, or plan review fees | If you build, remodel, change use, add signage, or need plan review. | Check Community Planning and Development before signing a lease or starting work. |
| Fire operational permit fees | If your operation, process, storage, event, or materials require a Denver Fire operational permit. | Check Denver Fire permit pages and the current fee schedule. |
| Colorado state filing or tax account fees | If you form an entity, file a trade name, get a state sales tax license, or renew a state license. | Use Colorado official filing pages. Do not rely on old screenshots or third-party fee lists. |
| Industry costs | Food plan review, inspections, commissary use, insurance, background checks, professional licenses, equipment, and inspections. | Open the official page for your exact business type and ask the agency what is required. |
What does this mean for me?
It means you should not ask only, “Do I need a business license?” In Denver, the better question is, “Which city, county, state, and federal steps match my activity and address?”
A home freelancer may only need to check zoning, trade name, taxes, and any state board. A seller, food business, host, contractor, childcare provider, or regulated shop may need more approvals.
Check the address, activity, taxes, and industry rules before spending money on signs, build-out, equipment, delivery apps, or ads.
Real-world examples
Home-based online seller
A handmade seller at home may need to check home occupation zoning, Colorado and Denver sales tax, trade name rules, and platform rules.
Food truck
A Denver food truck may need a mobile retail food license, commissary documents, inspections, fire review, sales tax setup, and parking rules.
Small retail shop
A shop owner should check zoning before signing a lease, then ask about occupancy, building, sales tax, signs, and fire rules.
Short-term rental host
A Denver host should check the primary residence rule, STR license, lodging taxes, platform rules, insurance, safety items, zoning, and license number display.
Common mistakes to avoid
- Assuming a Colorado LLC is the same as a Denver business license.
- Using an old Denver sales tax rate from a receipt, blog, or invoice template.
- Signing a lease before checking zoning, occupancy, signs, and build-out rules.
- Calling every permit a business license. Tax accounts, fire permits, food licenses, and contractor licenses are different.
- Opening a food business before checking plan review, commissary, mobile unit, and inspection steps.
- Forgetting Denver occupational privilege tax or Colorado employer accounts after hiring workers.
- Listing a short-term rental before checking primary residence, tax, insurance, and license display rules.
- Paying a third-party site for an EIN when the IRS provides EIN applications directly.
Phone and email scripts
Use these scripts when you contact an agency. Replace the bracketed words with your facts. Save the answer, date, and office.

Colorado state registration script
Hello, I am starting a Denver business as a [sole proprietor / LLC / corporation] using the name [name]. Do I need a Colorado entity filing, trade name, sales tax license, wage withholding account, unemployment insurance account, or workers’ compensation step for this setup?
Do not ask an agency to give legal advice. Ask which official forms, licenses, accounts, and departments apply to the facts you give them.
What to do if this does not work
If you cannot find your business type, do not guess. Try these steps:
- Search Denver’s license directory for related words, such as food, mobile, retail, contractor, tobacco, massage, security, rental, short-term rental, childcare, or peddler.
- Use the Denver contact form or portal help pages and ask which department owns your question.
- If the question is about address use, ask Community Planning and Development instead of the licensing office.
- If the question is about sales tax, use tax, lodger’s tax, or occupational privilege tax, ask Denver Treasury instead of the licensing office.
- If your business crosses city lines, check each city or county where you operate.
- If the answer affects a lease, tax filing, employment issue, or regulated license, talk with a qualified professional.
A compact compliance checklist
- Pick your business activity and business name.
- Check whether you need a Colorado entity filing or trade name.
- Check whether your Denver address allows the activity.
- Check Denver’s license directory for your business type.

- Get an EIN from the IRS if your structure or hiring plans require one.
- Save copies of licenses, permits, tax account letters, approvals, inspections, renewals, and agency emails.

FAQ
Does Denver have one general business license for every business?
No single Denver license clearly covers every business. Check the license directory, zoning, and city tax accounts.
Who handles business licenses in Denver?
Denver Department of Licensing and Consumer Protection handles many business and professional licenses. Building, tax, fire, and state matters may use other offices.
Do I need a Denver tax account if I already have a Colorado sales tax license?
You may. Denver is home-rule and administers local taxes. A Colorado sales tax license does not automatically cover Denver city tax accounts.
Can I run a business from my Denver home?
Maybe. Denver has home business and home occupation zoning rules. Some home businesses also need a license, tax account, or state license.
Do Denver food trucks need a local license?
Yes. Denver says food trucks, trailers, and carts operating in the city need a retail food establishment-mobile license.
Is an LLC the same as a Denver business license?
No. An LLC is a state entity filing. It does not replace Denver zoning, city tax accounts, licenses, or permits.
