Colorado LLC Formation: What to File and What It Costs

For a Colorado LLC that will make taxable retail sales, the key tax filing is a Colorado sales tax account or license application with the Colorado Department of Revenue, Taxation Division. Form CR 0100, Colorado Sales Tax and Withholding Account Application, is the paper form used to open a sales tax account or add a new physical location to an existing account.

This sales tax registration is separate from organizing the LLC. It applies to state sales tax and local sales taxes administered by the state. A Colorado Department of Revenue license does not necessarily cover a self-collecting home-rule city, so the LLC may need to contact the applicable city separately.

Colorado LLC Sales Tax Quick Facts

The LLC’s legal structure does not determine the tax treatment of every sale. The business should evaluate what it sells, where its transactions occur, and whether the relevant local jurisdiction is administered by the state or is a self-collecting home-rule city.

When a Colorado LLC Needs a Sales Tax License

A retailer required to collect Colorado sales tax must obtain and maintain a Colorado sales tax license. This obligation can apply even when the retailer does not have a physical presence in Colorado. An LLC should therefore avoid assuming that registration is unnecessary merely because it sells online, ships from another state, or does not operate a Colorado storefront.

The starting point is the nature of the LLC’s sales. Colorado imposes sales tax on retail sales of tangible personal property. Services generally are not taxable unless specifically taxed by law. A transaction containing both products and services may require further analysis because mixed transactions can be subject to additional rules.

Examples of information to review include:

• Whether the LLC sells physical products at retail or only provides services;
• Whether a transaction combines products, installation, subscriptions, labor, or other service components;
• Where the customer receives the product;
• Whether the business has one or more physical locations in Colorado;
• Whether the relevant city participates in state collection or administers its own sales tax; and
• Whether the LLC is already registered and is opening another physical location.

The Colorado Department of Revenue registration covers state and state-collected jurisdictions. An LLC operating in a self-collecting home-rule city must contact that city about separate licensing requirements. Those cities may use their own registration procedures, so state registration should not be treated as automatic local authorization everywhere in Colorado.

What to Prepare Before Filing

Preparing the business information before starting the application can reduce interruptions and help keep the account details consistent. The information should match the LLC’s business records and describe how the company actually operates.

• Legal business identity: Have the LLC’s exact legal name and any trade name or DBA used with customers.
• Identification details: Gather the federal and state identification information used in the LLC’s tax and business records.
• Ownership or responsible-party information: Be ready to identify the people responsible for the company and provide the details requested in the application.
• Business addresses: Distinguish the mailing address from each physical business location. Do not combine separate Colorado locations into a single location entry.
• Sales activity: Describe the products or services the LLC sells and determine whether it will make retail, wholesale, or both types of transactions.
• Start information: Identify when taxable sales begin so the requested license start information reflects actual business activity.
• Local jurisdictions: Identify the cities, counties, and special districts associated with the LLC’s locations and transactions, including any self-collecting home-rule cities.
• Existing account information: If the LLC already has a Colorado account, have that information available before adding another physical location.

Location review is especially important. A retailer maintaining multiple Colorado business locations must obtain a separate license for each location. Form CR 0100 can be used to add a new physical location to an existing account, but the additional location still needs its own license.

How to Apply and What It Costs

Apply to the Colorado Department of Revenue, Taxation Division, for the account or license covering state and state-administered local sales and use taxes. For a form-based application, use Form CR 0100, Colorado Sales Tax and Withholding Account Application. The form is used both to open a sales tax account and to add a new physical location to an existing account.

1. Confirm the need to register. Determine whether the LLC is a retailer required to collect Colorado sales tax.
2. Map the locations involved. Separate each physical Colorado location and identify any self-collecting home-rule city that may require direct contact.
3. Complete the application accurately. Use the LLC’s legal identity, describe its sales activity, and provide location-specific information.
4. Account for the license fee and deposit. Apply the fee associated with the license type and start period, and include the retail-license deposit when required.
5. Retain the resulting account and license records. Keep the information available for future location changes, tax administration, and renewal review.

For a wholesale or retail sales tax license with a start date from July through December 2026, the fee is $12. This fee applies to wholesale and retail licenses beginning during that period of an even-numbered year and does not apply to charitable licenses.

A $50 deposit is also required for a retail sales tax license. The deposit is automatically refunded after the business collects and remits $50 in state sales tax. Charitable organizations are exempt. For businesses with additional locations using an existing account number, the deposit generally is limited to the first location.

The deposit should be distinguished from the license fee. It is not an added sales tax rate, and its refund depends on the collection-and-remittance threshold described above. Businesses should also budget separately for any requirements imposed by a self-collecting home-rule city.

No single turnaround estimate should be used to schedule the LLC’s opening. The practical approach is to prepare the application before taxable sales begin and allow time to resolve location or jurisdiction questions.

Maintaining the License After Registration

Registration is not a one-time filing that can be ignored after the license is issued. A retailer required to collect Colorado sales tax must obtain and maintain its license. The LLC should keep its account details aligned with its sales activity, physical locations, and applicable jurisdictions.

Most Colorado sales tax licenses are valid for two years and expire at the end of each odd-numbered year. A license active in the current cycle expires December 31, 2027, unless it is revoked sooner. Some license types may have different terms, so the LLC should review the conditions attached to the particular license it receives.

Ongoing administration should include:

• Tracking the expiration date for each license;
• Maintaining a separate license for each Colorado physical business location;
• Reviewing registration needs before opening, closing, or changing a location;
• Keeping state-administered jurisdictions separate from self-collecting home-rule cities;
• Applying Colorado’s 2.9% state rate while also accounting for applicable city, county, and special-district taxes; and
• Keeping records of the retail-license deposit and the state sales tax collected and remitted toward its automatic refund.

For an LLC selling into several Colorado jurisdictions, location and tax-jurisdiction records are central to maintaining the account correctly. The state rate is uniform, but applicable local taxes depend on the transaction’s jurisdiction. Confirming the relevant jurisdiction before configuring invoices or sales systems can help the LLC distinguish state, state-administered local, and independently administered city obligations.
