Starting a Colorado business involves choosing a structure, checking local approvals, and setting up the tax and employer accounts your work requires. Use this checklist to connect each applicable task with its official route and optional help.
Colorado Business Requirements at a Glance
An LLC filing does not complete your business setup. Local licensing, home-rule sales taxes and employee programs need separate attention. Choose a structure first, then work through the steps that apply to your location and activity.

| Setup step | When it applies & what to budget | Your next step |
|---|---|---|
| Choose your business structureChoose first | An LLC is one way to separate business liabilities from personal assets; it is not required for every business. Colorado’s domestic LLC Articles of Organization filing fee is $50. Provider packages and add-ons are separate. Plan for the annual Periodic Report as well. | Understand Colorado LLC costs and filing, or use the official state filing route. If an LLC fits your business, ZenBusiness can help prepare and submit the formation filing. Starter begins at $0 plus state filing fees. Review optional services and renewal terms before ordering; licenses and ongoing business obligations are separate. Form an LLC with ZenBusinessAffiliate · Optional provider |
| Check licenses & your locationDepends on your work | Check the city or county for business licensing, zoning and home-occupation requirements. Food, childcare, construction and regulated professional services can need additional approvals. Entity registration does not replace these operating permissions. | Find your Colorado industry guide. Check the city or county for the location where you plan to operate. |
| Register a trading nameIf using an assumed name | A for-profit business operating under a name other than its true name generally files a Statement of Trade Name with the Secretary of State. This applies to sole proprietors using another name and entities using another trading name. A trade-name filing does not create an LLC or exclusive rights to the name. | |
| Get your federal tax IDIf an EIN is needed | An employer identification number (EIN) identifies your business for federal tax purposes. Whether you need one depends on your structure and activities. It is free from the IRS. If forming an LLC or corporation, form it before applying. | Check eligibility and get an EIN free. You do not need to buy an EIN service. |
| Register for sales taxIf making taxable sales | Check whether your sales require a Colorado sales-tax license and arrange the applicable state accounts. Self-collecting home-rule cities can have separate registrations and tax rules. Confirm the requirements where you sell; registering with the state alone may not complete the local process. | |
| Arrange business insuranceRequired coverage varies | Colorado generally requires workers’ compensation when you have one or more employees, including part-time workers, with limited exceptions. Check coverage before hiring. Liability, vehicle and property coverage depend on your operations, leases and customer contracts; an LLC does not replace insurance. | Check Colorado workers’ compensation rules. Optional quote service: Simply Business can help you explore business insurance. Coverage and availability depend on your trade and underwriting. Get business insurance quotesAffiliate · Optional provider |
| Separate money & keep recordsPractical setup | Choose how you will separate business receipts and expenses, reconcile transactions and save tax records. Compare account fees, cash-deposit access and bookkeeping needs. Account-opening documents depend on the provider and business structure. | Prepare your formation or trading-name documents and tax ID, then compare business accounts. Set up a recordkeeping routine before your first payment. |
| Put customer agreements in writingDepends on your service | Agree on the work, price, payment dates, exclusions and cancellation terms before starting. A general service-agreement template may help with routine work; regulated or complex jobs can need specific contract terms or legal review. | Optional document service: use LawDepot to customize a service agreement, then check that it fits your work. Create a service agreementAffiliate · Optional provider |
| Set up invoices & paymentsChoose your payment method | Decide how customers will pay and when invoices are due. Compare transaction fees, hardware costs and payout timing. Buying a particular payment service is not a state requirement. | Optional payment service: explore Square for accepting customer payments and compare its fees with your expected sales. Explore Square paymentsAffiliate · Optional provider |
| Plan startup costs & cash reservesBorrowing is optional | Add filing costs, equipment, insurance and operating expenses before deciding whether to borrow. Financing options depend on revenue, time in business, credit and lender criteria. A new, pre-revenue business may not qualify. For local lenders and eligibility, compare Colorado business loans. | Optional comparison service: SuperMoney Business Financing lets you explore funding options, subject to eligibility. Compare total repayment cost and payment frequency. Compare business financingAffiliate · Optional provider |
| Prepare for employeesIf hiring | Set up applicable unemployment insurance and wage withholding accounts, new-hire reporting and payroll records. Check Colorado FAMLI registration and reporting separately; using an approved private leave plan still involves the state’s approval process. | Check employer account setup |
| Calendar reports & renewalsFor your entity and licenses | A Colorado LLC files a $25 Periodic Report each year. Check the reporting month and filing window on your business record. Track tax, license and insurance deadlines separately. Individual and non-reporting-entity trade names generally need annual renewal; a reporting entity’s trade name depends on its status. | Check the official reporting and renewal guidance. Paid filing help is optional and may cost extra. |

How to Start a Business in Colorado (Step by Step)
Step 1: Choose Your Structure and Register It
An LLC is one option, not a requirement for every business. Compare ownership, liability and ongoing obligations before choosing. If an LLC fits your plans, the filing instructions below apply; our Colorado LLC guide explains the costs and options.
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: See how Colorado compares in our 51-state business license requirements table.
- 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).

How Long Do New Businesses Last in Colorado?
The Bureau of Labor Statistics follows every private-sector establishment in Colorado from the year it opens. Of the businesses opened in March 2024, 75.9% were still operating one year later. Among those opened in March 2020, 48.5% reached the five-year mark — 2.9 points below the national 51.4% — and 31.9% of the March 2015 cohort made it to ten years.
Two things keep those numbers from reading as grimly as they look. A closed establishment is not always a failed one: the BLS count includes owners who sold, merged, moved, or retired. And the businesses that last, grow — nationally, establishments reaching age ten average 11.7 employees, up from 4.4 when they opened.

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.
