Starting a Business in Colorado: Licenses, Permits & Requirements (2026)

Last updated: April 22, 2026

Three things set Colorado apart from most other states when you are starting a business here. First, Colorado’s LLC formation fee is $50 — one of the lowest in the country (Texas charges $300, California $70 plus an $800 minimum franchise tax). Second, Colorado has a mandatory state paid family leave payroll contribution called FAMLI (Family and Medical Leave Insurance) that applies to every employer with Colorado employees — most other states have no equivalent. Third, Colorado’s workers’ compensation requirement kicks in at one employee with no minimum threshold or industry exemption, which is more aggressive than many states. Plan for all three from day one.

This guide compiles the specific Colorado agency requirements, portal links, fee amounts, and city-level variations that apply to starting a business in Colorado in 2026. The source agencies referenced are the Colorado Secretary of State, Colorado Department of Revenue, Colorado Department of Labor and Employment (CDLE), Colorado FAMLI Division, and DORA (Department of Regulatory Agencies).

How to Start a Business in Colorado (Step by Step)

Step 1: Form Your Colorado LLC

File Articles of Organization online through the Colorado Secretary of State eCorp portal. Colorado does not accept paper LLC filings. Cost: $50. Processing is near-instant in most cases.

Your LLC name must include “LLC,” “L.L.C.,” or “Limited Liability Company” and must be distinguishable from existing entity names in the SOS database. Run a name search at coloradosos.gov before filing.

Registered agent: Your LLC must have a registered agent with a physical street address in Colorado (P.O. boxes not accepted). You can serve as your own registered agent if you have a Colorado physical address, or hire a third-party registered agent service.

Annual Periodic Report: Colorado LLCs must file a Periodic Report every year. The report is due during a 5-month window around your LLC’s anniversary month (two months before through two months after). Filing fee: $25. Late penalty: $50. Failure to file leads to administrative dissolution of your LLC — set a calendar reminder for this.

Trade Name (DBA): If you operate under a name different from your LLC’s legal name, file a Statement of Trade Name with the Secretary of State for $20 online. Annual renewal fee: $5. LLCs in good standing do not need to separately renew their trade name.

Get your free federal EIN immediately at IRS.gov — you need it before you can register for state taxes, open a business bank account, or hire employees.

Step 2: Register for State Taxes Through MyBizColorado

Colorado’s unified business registration portal is MyBizColorado (mybiz.colorado.gov). Use it to register for your sales tax license, unemployment insurance account, and FAMLI in a single session.

Colorado Sales Tax

Colorado’s state sales tax rate is 2.9% — among the lowest base rates in the country. The real complexity comes from local taxes:

• Home rule cities collect their own sales tax separately from the state. Denver, Boulder, Colorado Springs, Fort Collins, Pueblo, and dozens of other Colorado cities are home rule jurisdictions. They administer their own sales tax, maintain their own rates, and require separate registration — not through the Colorado DOR but directly with the city. If you sell in Denver, you collect both the state 2.9% (remitted to Colorado DOR) and Denver’s city tax (remitted directly to Denver Finance).
• Combined rates: range from 2.9% (state-only unincorporated areas) up to approximately 11.65% in the highest home-rule jurisdictions depending on location. Denver’s combined rate runs approximately 9.15% after the 2025 Denver Health ballot measure.
• Sales tax license: Free to obtain at MyBizColorado. Renewal fee: $16 every 2 years.

Service businesses: Colorado generally does not impose state sales tax on services. Janitorial/cleaning service charges are not taxable at the state level. However, separately billed consumable items (paper towels, cleaning supplies) sold as part of a service contract are taxable. Local home rule jurisdictions may tax services differently — verify in each city you operate.

Colorado Income Tax

Colorado uses a flat income tax rate of 4.4% on all Colorado taxable income (tax year 2025). No brackets — the same rate applies regardless of income level.

• Pass-through entities (LLCs, S-corps, partnerships): income flows to owners’ personal Colorado returns at 4.4%
• File and pay through the Colorado Department of Revenue (tax.colorado.gov)
• Colorado is a TABOR (Taxpayer’s Bill of Rights) state — revenue surpluses can trigger future rate adjustments. The 4.4% rate was set following the 2023 Proposition HH adjustment; verify the current rate each year

Step 3: Register for FAMLI — Colorado’s Mandatory Paid Family Leave Contribution

FAMLI (Family and Medical Leave Insurance) is a Colorado-specific mandatory payroll contribution that most other states do not have. If you have Colorado employees, you must participate.

• 2026 rate: 0.88% of wages (reduced from 0.9% in 2025)
• Split for employers with 10+ employees: 0.44% paid by employer + 0.44% withheld from employee wages
• For employers with 1-9 employees: Exempt from the employer share but must still withhold and remit the 0.44% employee contribution
• Wage cap: Premiums apply only on wages up to the federal Social Security wage cap ($184,500 in 2026)
• Register at: famli.colorado.gov or through MyBizColorado. Register before your first payroll.
• What employees receive: Up to 12 weeks of paid family or medical leave per year. Benefits have been active since January 2024.

FAMLI is one of the most significant differences between running a business in Colorado and running one in most other states. Budget for it in your payroll model from day one. For an employee earning $60,000/year, the total 2026 FAMLI obligation is $528 ($264 employer share + $264 withheld from employee wages for a 10+ employee business).

Step 4: Get Workers’ Compensation Insurance

Colorado requires workers’ compensation insurance for any employer with one or more employees — no threshold, no industry exemption, no exceptions for part-time or family members.

Situation	Colorado Requirement
1+ full-time employees	Workers’ comp required
1+ part-time employees	Workers’ comp required
Family members on payroll	Workers’ comp required
Sole proprietor with no employees	Optional (owner may elect coverage)
True independent contractors	Not required — but misclassification is heavily audited

Where to get coverage: Purchase from any licensed private insurer or from Pinnacol Assurance, Colorado’s largest workers’ comp carrier. Pinnacol is required by Colorado law to cover any eligible employer who applies — it is the market of last resort. Penalties for operating without required coverage include fines and personal liability for the full cost of any workplace injury claim. Overseen by the Colorado Division of Workers’ Compensation (CDLE).

Step 5: Get Local Business Licenses and Industry-Specific State Licenses

City and County Licensing

Colorado has no statewide general business license. Local licensing requirements vary by city:

• Denver: Regulated industries (food service, alcohol, short-term rentals, security, towing, body art, and others) require a license from Denver’s Department of Licensing and Consumer Protection (rebranded from Department of Excise and Licenses in late 2025 following voter approval). General businesses not in regulated categories need no city license — but all businesses selling in Denver must register for Denver’s local sales tax separately from the state. Apply at denvergov.org.
• Colorado Springs: City sales tax license required if collecting sales tax within city limits. Industry-specific licenses through Development Services. Apply at coloradosprings.gov.
• Aurora: Business license required through Aurora’s Community Development Department. Fees and requirements vary by business type.
• Fort Collins: Sales tax license required for businesses selling taxable items in Fort Collins (the city administers its own sales tax). Apply at fcgov.com/salestax.
• Boulder: Business license required through the City of Boulder. Boulder collects its own sales tax separate from state administration.
• Lakewood: Business license required through Lakewood’s Finance Department.

DORA Professional Licenses (State Level)

Colorado’s Department of Regulatory Agencies (DORA) through its Division of Professions and Occupations (DPO) licenses a wide range of industries. If your profession requires a state license, it almost certainly comes through DORA. Key licensed professions include:

• Cosmetologists, barbers, hairstylists, estheticians, nail technicians (Office of Barber and Cosmetology Licensure)
• Private investigators (Office of Private Investigator Licensure)
• Electricians and plumbers (State Electrical and Plumbing Boards)
• Real estate agents (Division of Real Estate)
• Insurance producers (Division of Insurance)
• Mental health professionals, veterinarians, chiropractors, and many others

Contact DORA at 303-894-7800 or visit dora.colorado.gov.

Colorado’s Unique Tax and Payroll Environment

Three aspects of Colorado’s tax and payroll structure require specific planning compared to most other states:

1. Home rule sales tax complexity. Colorado has more home rule municipalities than almost any other state. These cities administer their own local sales tax, meaning if you sell in Denver, Boulder, Colorado Springs, Fort Collins, or dozens of other cities, you deal with multiple tax authorities. Retail businesses and food service operators must verify which jurisdictions are home rule before setting up tax collection — operating with the wrong rate or filing with the wrong agency creates penalties.

2. FAMLI adds real payroll cost. At 0.88% of wages on up to $184,500 per employee, FAMLI adds overhead that businesses in most other states don’t carry. Combined with Colorado’s unemployment insurance taxable wage base of $30,600 (up from $27,200 in 2025), the total payroll tax burden per employee is higher than states without paid leave laws. Factor this into hiring projections.

3. Independent contractor rules in Colorado. Colorado applies an “ABC test” to determine whether a worker is an employee (subject to workers’ comp, FAMLI, UI) or a true independent contractor. The rules are not as strict as California’s AB5, but Colorado labor enforcement has increased audit activity. Misclassifying workers to avoid FAMLI and workers’ comp obligations creates significant liability. When in doubt, consult the CDLE guidelines before classifying workers as contractors.

Colorado Market Context: The Front Range and Beyond

The Front Range corridor (Denver-Fort Collins-Colorado Springs) has been one of the fastest-growing metro areas in the United States for a decade. This creates strong, sustained demand for small business services:

• Denver metro: Approximately 2.9 million people and growing. Sustained residential and commercial construction creates recurring demand for cleaning, HVAC, landscaping, and daycare across the suburbs.
• Technology and startup hub: Boulder and the Denver Tech Center (southeast Denver) have high concentrations of tech workers and startups with above-average household incomes — strong demand for professional services and a high business formation rate.
• Tourism and resort economy: Aspen, Vail, Breckenridge, and Telluride create seasonal demand for cleaning services, food trucks, and landscaping that follows resort calendars, distinct from Front Range year-round patterns.
• Military installations: Colorado Springs hosts Fort Carson, Peterson Space Force Base, NORAD/USNORTHCOM, and the U.S. Air Force Academy — stable, year-round service demand with federal contractor opportunities.
• Altitude: Denver sits at 5,280 feet; mountain communities at 7,000-11,000 feet. Altitude affects food truck operations (propane output), HVAC sizing calculations (different load requirements), and landscaping plant selection (xeriscape and native plant demand driven by water scarcity).

Frequently Asked Questions

How much does it cost to start an LLC in Colorado?

The Articles of Organization filing fee with the Colorado Secretary of State is $50 online — one of the lowest LLC formation fees in the country. Colorado does not accept paper LLC filings. After formation, your annual Periodic Report costs $25/year, due during a 5-month window around your LLC’s anniversary month. A late penalty of $50 applies. Optional costs: trade name (DBA) registration at $20, and registered agent service if you use a third-party provider.

What is FAMLI and does it apply to my Colorado business?

FAMLI (Family and Medical Leave Insurance) is Colorado’s mandatory state paid family leave program, active since 2023. If you have Colorado employees, you must participate — there is no small-employer exemption from withholding the employee share. The 2026 contribution rate is 0.88% of wages, split 0.44% employer / 0.44% employee for businesses with 10+ employees. Employers with 1-9 employees are exempt from the employer share but must still withhold and remit the 0.44% employee contribution. Premiums apply on wages up to $184,500 (2026 Social Security wage cap). Register at famli.colorado.gov.

Does Colorado require workers’ compensation for part-time employees?

Yes. Colorado’s workers’ compensation requirement has no minimum employee threshold — coverage is required the moment you hire any employee, full-time or part-time, including family members. This is more aggressive than states like Georgia (required at 3 employees). The only workers exempt are true independent contractors. Purchase from any licensed private insurer or from Pinnacol Assurance, which is required by law to cover any eligible Colorado employer who applies.

Does Colorado have a general business license?

Colorado has no statewide general business license. However, if you sell taxable goods or services, you need a sales tax license (free at MyBizColorado). Most cities also require local registration — Denver requires city-specific licenses for regulated industries and separate registration for Denver’s local sales tax. Some industries require a state license through DORA (cosmetologists, private investigators, electricians, plumbers, real estate agents, and others).

Why is Colorado sales tax complicated for small businesses?

Colorado has more home rule municipalities than almost any other state. These cities — including Denver, Boulder, Colorado Springs, Fort Collins, and dozens of others — administer their own sales tax separately from the state. You may need to register with multiple local tax authorities, maintain separate accounts, and file returns with each jurisdiction where you sell. The state rate is 2.9%, and combined rates (state + local) run from 2.9% in state-only areas up to approximately 11.65% in the highest home-rule jurisdictions depending on location. Contact the Colorado DOR or each city’s finance department for current rates and registration requirements.

What is Colorado’s income tax rate for small businesses?

Colorado uses a flat income tax rate of 4.4% on all Colorado taxable income for tax year 2025. No brackets — the same rate applies whether your income is $30,000 or $3 million. LLCs and S-corps are pass-through entities; income flows to owners’ personal Colorado returns at 4.4%. Colorado is a TABOR state, meaning revenue surpluses can trigger future rate adjustments — verify the current rate each year at tax.colorado.gov.
