Start an LLC in Colorado

Choosing a name for your Colorado LLC is both a legal requirement and an important branding decision. While you’ll need to follow state rules, your name should also position your business for long-term success by being clear, memorable, and aligned with your goals. To make the process more manageable, consider the following guidelines:

• Meet Colorado requirements. Include an appropriate LLC designator (like “LLC” or “Limited Liability Company”) and ensure your name is distinguishable from other registered businesses in the state.
• Reflect what you do. Choose a name that reflects your products or services so potential customers understand what your LLC offers.
• Make it memorable. Aim for something simple, easy to spell, and easy to recall to help your business stand out.
• Check domain availability. Look for an available website domain that matches your business name—or a close variation—to support your online presence.
• Think long-term. Pick a name that can grow with your business and won’t limit you if you expand in the future.

Once you’ve chosen a business name, the next step is to register a domain for your website. Think of it as your virtual street address—without it, people won’t be able to find your business online. Here are a few things to keep in mind before registering your domain:

• Act quickly. Domains are first-come, first-served—registering early ensures you get the name you want before someone else does.
• Lock in your brand. Registering your domain secures your business identity and prevents competitors from claiming similar names.
• Protect multiple extensions. Consider registering common variations (like .com, .net, .co) to safeguard your brand and reduce confusion.
• Keep renewal in mind. Set up auto-renewal or reminders to maintain ownership and avoid losing your domain unexpectedly.
• Use a trusted provider. Register through a reliable service (like Northwest) to ensure your domain is secure and easy to manage.

All Colorado LLCs are required to appoint a registered agent. Your registered agent could be you, another individual, or a registered agent company that is authorized to receive service of process (lawsuits and other legal documents) on behalf of your business. Your registered agent’s name and address will need to be included on your Colorado Articles of Organization.

To formally start your LLC, you’ll need to file the Articles of Organization. In Colorado, you are required to submit your Articles electronically, through the Colorado Secretary of State website. You’ll need the following information about your LLC:

• Company name. Include limited liability company, LLC, or L.L.C.
• Principal office address. Must be a physical street address.
• Mailing address. P.O. Boxes are allowed.
• Registered agent. Whoever will accept legal mail in person on behalf of your business.
• Registered agent address. Must be a Colorado street address.
• Registered agent consent. Confirm that your registered agent has agreed to be your agent.
• Management structure. Whether your LLC will be managed by members or managers.
• At least one member. Check the box to confirm your LLC has at least one member.
• Optional provisions. Add anything extra here. For example: a list of your members’ names.
• Delayed effective date (optional). If you want, add a future start day for your LLC.

Note: Every piece of information on this form becomes part of the public record.

An operating agreement explains how your LLC will function in important situations. It should cover how much each member contributed, how profits and losses will be allocated, how you’ll conduct votes, how membership can be transferred, and how you’ll dissolve the business, if you ever need to.

Feel free to customize your operating agreement, but keep in mind there are a few major situations every agreement should cover:

• Initial investments
• Profits, losses, and distributions
• Transfers of membership interest
• Voting rights and decision-making powers
• Management
• Dissolution

Other than that, include what you want as long as it doesn’t violate either Colorado law or your Articles of Organization. You can also check out our attorney-drafted Operating Agreement.

An EIN (Employer Identification Number) is similar to a social security number, except for businesses. It’s the number the IRS will use to identify your business on tax filings.

You can get an EIN directly from the IRS for free, either on the IRS website (the fastest way) or by mail. You can do this yourself or hire us to do it for you. If you don’t have a social security number, you’ll need to mail in the paper form.

In Colorado, you must file an annual report for your business, called the Colorado Periodic Report. The report’s main purpose is to ensure the state knows if something like your business ownership or contact information changes.

Your periodic report will be due during the anniversary month in which the LLC was originally formed, but can also be filed up to two months before that month, or up to two months after with no penalty. So if you formed your LLC on October 22nd, your periodic report would be due by October 31st of the following year (but you can submit it between August 1st and December 31 without accruing fines).

If you’re sick of paperwork, you can also hire us to file your annual report for you.
