Colorado Trade Name Registration

Registering a Colorado trade name, also known as a DBA, is easy!

Your Colorado trade name must be unique and must also meet Colorado’s business name requirements.

First, visit the Colorado Name Availability Search website and search for your new DBA name to make sure it isn’t already in use.

Next, review the Colorado naming requirements. In Colorado, your trade name should not include:

  • Any term that would violate any Colorado law. For example, your business name cannot include obscenities or references to illegal activities.
  • Words that could confuse your business with a government agency (FBI, Treasury, State Department, etc.).

We recommend checking if your name is available as a web domain (URL). You might not plan on starting a business website today, but you may want to prevent others from acquiring your URL.

Renew Your Trade Name With the State
Trade names for sole proprietorships and partnerships in Colorado expire on the first day of the month after the one-year anniversary of the filing. For example, if a trade name was registered on October 10, it would expire on November 1 of the following year.

Trade names need to be renewed online before the expiration date. They can be renewed at any point during the three months prior to the expiration date. The renewal fee is $5.

Trade names for LLCs and corporations do not expire as long as the company remains in good standing. If the company falls out of good standing, the trade name will expire after one year. If the company gets back to good standing, the trade name expiration date will be canceled.

If your trade name expires and you would like to use it again, you will have to file a new registration form.

After Filing Your Colorado DBA

If filing a DBA marks the beginning of your business journey, then there are a few more steps that you should take before getting started:

  • Create your Business’s Website - Every business needs a website. Luckily, drag-and-drop builders like GoDaddy and Wix make the job quick and easy. Check out our Best Website Builder article to find the tool that’s best for you.
  • Get your Business Finances in Order - You’ll need to separate your business finances from your personal ones. This is accomplished by opening a business bank account. If your business has long lead times or other cash flow irregularities, you can also look into a business credit card.
  • Protect Your Business - While an LLC will help to protect your personal assets in the case of a lawsuit, your business’s assets also need protection. Having the right business insurance will ensure that you’re covered if the worst happens. Most businesses start with general liability insurance as their base coverage.

DBA Colorado FAQ

You can have as many DBAs as you can afford to create and are able to keep track of. Each one comes with additional incremental expenses and paperwork, meaning more is not necessarily better.

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you need one for your business, read our What is an EIN guide.

No. An LLC is a business entity, while a DBA is just a name for a business.

Sole proprietorships are often confused with DBAs, but they are not the same: a sole proprietorship is a business entity, therefore it can choose to become an LLC.

To learn how to form an LLC, visit our Form an LLC state guides.

A DBA can only have Inc. in the name if the business entity the DBA is attached to is a corporation.

Holding a rental property in your name and with a DBA will not afford you any protection. The best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. In any case, it is always best to consult an attorney.

Getting a DBA is often a better choice than changing your business’s legal name. If you want to rebrand your company or focus on another line of business, filing for a DBA is a simpler process than filing for a legal name change.

Some state-level laws prevent DBAs that are too similar to existing ones from being used, but this varies from state to state. It is possible to trademark a DBA, which would offer stronger protection across state lines.
