Westminster Business License: How to Register and What It Costs

Getting a business license in Westminster, Colorado involves navigating both city and state requirements. Unlike some states that issue a single catch-all business license, Colorado requires you to file separately with the Secretary of State, the city of Westminster, and potentially the Department of Revenue depending on your business type. This guide walks you through exactly what you need, the steps to complete registration, and the costs involved.

What You Need Before Starting: Required Materials and Information

Before you file anything, gather these materials. Having them ready upfront prevents delays and rejected applications.

For Secretary of State Filing (If Forming an LLC or Corporation)

• Business name. Westminster business names must follow Colorado rules: if you are forming an LLC, the name must include "LLC," "Limited Liability Company," or similar language. Names must be distinguishable on the Secretary of State's records, meaning "ABC Inc" and "abc inc" are treated as identical. Check name availability before filing.
• Registered agent information. As of July 2025, a registered agent must either be an individual with a current Colorado driver's license or state ID living in Colorado (or with a usual place of business there), or an entity in good standing with the SOS that has a Colorado business address. The registered agent's name and ID number must match their credential exactly. The agent's address must be a physical street address in Colorado where documents can be received during business hours, never a P.O. box.
• Ownership and structure details. For an LLC, you need member names and ownership percentages. For a corporation, you need director and officer information.
• Business address in Westminster. A physical address in Westminster is required.

For Westminster City Business License

• Business location address. The exact physical address of your Westminster operation.
• Business description. A clear description of the work your business performs or products it sells.
• Ownership documentation. The city may request proof of ownership or a lease agreement for your Westminster location.
• Payment method. Credit card or check (verify current payment options with the city).

For a Sales Tax License (If Selling Goods or Taxable Services)

• Federal Employer Identification Number (EIN). Apply for one free from the IRS at irs.gov if your business structure requires it (most LLCs and all corporations do).
• Colorado sales tax license application details. Business name, address, ownership structure, and expected monthly sales.

Step-by-Step Westminster Business Registration Process

Step 1: Choose Your Business Structure and Reserve Your Name (2 to 5 Business Days)

Decide whether you will form an LLC, a corporation, or operate as a sole proprietor or partnership. If you want to form an LLC or corporation in Colorado, you file with the Colorado Secretary of State, regardless of where you operate.

Before filing, search for your proposed name at the Colorado Secretary of State's business entity search portal. The search is free and instant. If the name is available and you want to hold it while you prepare your full application, you can file a name reservation for $25. A name reservation lasts 120 days, giving you time to finalize your business structure and file your full formation document.

If you plan to operate under a different name than your legal entity name (for example, "John Smith's Plumbing" when your LLC is "Smith Home Services LLC"), Colorado requires you to register that as a trade name with the Secretary of State. The fee is $20 online, with a $5 renewal fee annually.

Step 2: File with the Colorado Secretary of State (Instant to 7 Business Days)

If you are forming an LLC or corporation, file your formation document through the Colorado SOS Business Organizations online filing system.

For an LLC: File Articles of Organization for a Limited Liability Company. The filing fee is $50.

For a Corporation: File Articles of Incorporation for a Profit Corporation. The filing fee is also $50.

Online filings are processed in real time and your business record updates immediately after successful payment, unless you have specified a delayed effective date. Most online applications are active within minutes. Paper filings (rare; only a few documents require paper submission) take about 7 to 10 business days.

Keep your Secretary of State filing confirmation email and document number for your records. You will need proof of state registration when you apply for your city business license and sales tax permit.

Step 3: Apply for a Westminster City Business License (3 to 14 Business Days)

After you have your state filing, apply for a Westminster city business license. Westminster issues business licenses through its city government; the process and requirements differ from the state filing.

Where to apply: Contact the City of Westminster, Business Licensing Department directly. As of September 2026, you can inquire about applications at Westminster's city offices or online (check the city's official website for the most current application portal and email).

What to submit:

• Completed Westminster business license application (provided by the city).
• Proof of your Colorado Secretary of State filing (if you formed an LLC or corporation), or a copy of your identification if you are a sole proprietor.
• Proof of business location (lease, deed, or owner authorization letter).
• A description of your business activities.
• Payment for the business license fee (amount varies by business type and city; confirm the current fee schedule with Westminster before applying).

Processing time: Westminster typically processes applications within 3 to 14 business days, though timelines vary based on completeness of your application and current city workload. Submitting a complete application the first time significantly speeds up approval.

Step 4: Apply for a Colorado Sales Tax License (If Applicable) (1 to 3 Business Days)

If your business sells tangible goods or taxable services in Colorado, you must obtain a sales tax license from the Colorado Department of Revenue, Taxation Division. This is separate from your business license.

Colorado sales tax rate: The state sales tax is 2.9%. However, Westminster is a home rule city, which means it collects additional sales tax independently. You will need to register with both the state and the city.

How to apply: Apply online at tax.colorado.gov/how-to-apply-for-a-colorado-sales-tax-license. The application is free; there is no fee to obtain a Colorado sales tax license.

What you will need:

• Your Federal EIN (or Social Security Number if you are a sole proprietor).
• Your business structure (LLC, corporation, sole proprietor, partnership).
• Your Westminster business address.
• Expected monthly sales figures.

Processing: State sales tax licenses are typically issued within 1 to 3 business days of submission. You will receive a sales tax license number that you will use to file monthly or quarterly sales tax returns with Colorado.

Home rule city registration: Because Westminster is a home rule city, after you receive your state sales tax license, contact Westminster's tax or finance department to register for the local sales tax collection requirement as well. This is a separate registration from your city business license.

Tips to Avoid Common Mistakes

1. Verify Your Registered Agent Information Matches Your Colorado ID Exactly

As of July 2025, the Colorado Secretary of State requires that a registered agent's name and ID number match their driver's license or state ID card exactly. Mismatches cause filing rejections. If your agent does not have Colorado ID, request a mailed agent passcode (valid 45 days after request).

2. Use a Physical Address for Your Registered Agent, Never a P.O. Box

The registered agent address must be a physical street address where documents can be received during normal business hours. P.O. boxes are not accepted, and using one will delay or reject your filing.

3. Check Name Availability Before Paying for Articles

Search the Colorado SOS database for free before filing. Punctuation and capitalization do not make names distinguishable, so "ABC Inc," "abc inc," and "A.B.C., Inc." are all considered identical. If your name is not available, you will lose your $50 filing fee if you submit anyway (the filing will be rejected).

4. Do Not Forget the Home Rule City Sales Tax Registration

Westminster collects sales tax independently because it is a home rule city. Getting a state sales tax license is not enough. After state registration, contact Westminster to register for local sales tax collection to avoid penalties and back taxes later.

5. Clarify Which Department Issues Your Industry-Specific License

Many professions (contractor, real estate agent, daycare, medical services, food service) require additional licenses from the Colorado Department of Regulatory Agencies (DORA), the Colorado Department of Health and Environment, or the city itself. Business licenses from the Secretary of State and the city do not cover these. Research your industry requirements early.

6. Mark Your Calendar for Annual Periodic Report Filings

Colorado requires an annual Periodic Report ($25 fee) filed in your entity's periodic report month (based on your formation anniversary). The report can be filed up to two months early or two months late without penalty. Failing to file makes your entity "Delinquent" and can result in loss of liability protection and tax penalties. Set a calendar reminder.
