What You'll Need to Start a Business in Commerce City

Before filing paperwork, gather the following:

Business structure decision, Limited Liability Company (LLC), S-Corporation, C-Corporation, or sole proprietorship. Each has different filing costs and tax consequences. An LLC is the most common choice for small businesses in Commerce City because it offers liability protection with simpler tax filing.
Proposed business name, Must be distinguishable from existing Colorado business names. Check availability at the Colorado Secretary of State before filing.
Registered agent information, As of July 1, 2025, Colorado requires all registered agents to either hold a valid Colorado driver's license or state ID card (and either live in Colorado or have a place of business there), or to have requested a mailed agent passcode from the Secretary of State. The registered agent's physical street address in Colorado must be where documents can be received during business hours.
Filing fees, $50 to file an LLC or corporation, plus $25 annually for the periodic report. A Doing Business As (DBA) filing costs $20.
Sales tax permit application, If selling tangible goods, you'll need a Colorado sales tax license and likely a Commerce City business tax registration.
Federal Employer Identification Number (EIN), Free from the IRS; required if you have employees or operate as a partnership or corporation.

Step-by-Step Process to Start a Business in Commerce City

Step 1: Choose Your Business Structure

Decide between an LLC, S-Corporation, C-Corporation, or sole proprietorship. An LLC formed in Colorado typically costs $50 to file and has a $25 annual periodic report due. There is no franchise tax in Colorado; income passes through to you at the state's flat 4.40% income tax rate. A corporation also costs $50 to file with a $25 annual report.

This is not legal or tax advice. Consult a Colorado business attorney or CPA to determine which structure suits your situation, especially if you have partners, employees, or complex tax circumstances.

Step 2: Reserve or Check Your Business Name

Search the Colorado Secretary of State business database at https://www.coloradosos.gov/biz/BusinessEntityCriteriaExt.do to verify your name is available and distinguishable. Punctuation and capitalization do not make a name distinguishable, so "ABC Inc" and "abc inc" are treated as the same name.

If you want to secure the name before filing, you can reserve it for 120 days for a $25 fee through the Secretary of State online portal.

Step 3: Prepare Your Articles of Organization (for LLCs) or Articles of Incorporation (for Corporations)

These documents establish your business with the state. For an LLC, file Articles of Organization. For a corporation, file Articles of Incorporation. Both must include:

Your business name (with LLC or corporation designation)
The address of your registered agent (a physical Colorado street address)
Name and contact info for the registered agent
Your principal place of business address

The Colorado Secretary of State provides fillable forms on their online filing portal at https://www.coloradosos.gov/pubs/business/fileAForm.html. Most documents must be filed online.

Step 4: File with the Colorado Secretary of State

Submit your Articles of Organization or Incorporation through the Colorado SOS Business Organizations online filing system. Online filings process in real time, and your business record is updated immediately after successful payment. Pay the $50 filing fee. You'll receive confirmation and your official formation documents within minutes.

Step 5: Obtain Your Federal Employer Identification Number (EIN)

Apply for an EIN from the IRS at https://www.irs.gov using Form SS-4. The IRS issues EINs free of charge. You can apply online and receive your EIN immediately. You will need your EIN to open a business bank account, hire employees, and file federal tax returns.

Step 6: Register for a Colorado Sales Tax License (if applicable)

If you sell tangible goods, you must register for a Colorado sales tax license. Apply online at the Colorado Department of Revenue: https://tax.colorado.gov/how-to-apply-for-a-colorado-sales-tax-license. Colorado's state sales tax rate is 2.9%; Commerce City may apply additional local sales taxes, and home rule cities collect separately. Confirm local requirements with the Commerce City Finance Department.

Step 7: Register with Commerce City

While Colorado issues no general statewide business license, Commerce City requires local business tax registration for most business types. Contact the Commerce City Finance Department to determine what permits or licenses your specific business needs. Some occupations, like cosmetology, healthcare, or professional services, require separate licensing from the Colorado Department of Regulatory Agencies (DORA).

Step 8: Open a Business Bank Account

Visit a local bank in Commerce City with your formation documents, EIN, and identification. A separate business account keeps personal and business finances distinct, which is essential for liability protection and tax filing.

Step 9: File Your First Periodic Report

Colorado requires an annual Periodic Report ($25 fee) filed in your entity's anniversary month. You can file as early as two months before or as late as two months after that month with no penalty. Missing the deadline makes your entity Delinquent with the Secretary of State, which can affect your ability to do business.

Tips and Common Mistakes to Avoid

Don't skip the registered agent requirement. As of July 1, 2025, your registered agent must meet Colorado's new identity verification rules: a valid Colorado driver's license or state ID, or a mailed passcode. This is mandatory and cannot be waived.
Confirm your local requirements early. Commerce City and Colorado both have filing and licensing rules. Some industries require state professional licenses from DORA before you can legally operate. Check this before filing to avoid delays.
Distinguish your name carefully. The Secretary of State treats similar names as identical if they differ only in punctuation or capitalization. Search thoroughly to ensure your name is truly unique.
Mark your periodic report deadline. File your $25 annual Periodic Report on time. Set a calendar reminder two months before your formation anniversary to avoid missing the filing window.
Separate business and personal finances immediately. Open a business bank account before running any transactions. Mixing funds undermines liability protection and complicates taxes.
Plan for sales tax if you sell goods. If you sell physical products in Commerce City, you need a sales tax license and must collect and remit sales tax. This is a common requirement people overlook.

Expected Timeline and Results

The process typically takes 1 to 3 weeks from start to finish, depending on how quickly you gather documents and whether you need additional professional licenses.

Immediate (same day): File Articles of Organization online with the Colorado SOS. You'll have a live business record within minutes of payment.
1 to 3 business days: Receive your EIN from the IRS (online applications are instant; mail applications take longer).
1 week: Register for a Colorado sales tax license if applicable.
1 to 2 weeks: Complete Commerce City local registration and obtain required permits.
Ongoing: File your $25 Periodic Report every year during your business's anniversary month.

Once complete, your business is legally formed, you can hire employees, open a business bank account, apply for loans, and begin operations.
