Do I need a DBA in Colorado?

Colorado requires that all sole proprietorships, general partnerships, domestic limited partnerships (DLPs), active and/or dissolved reporting entities, and trusts that regularly transact business in Colorado under a name different from their legal name, must file a DBA with the Colorado Secretary of State.

What is a DBA?

Every business has a legal name. For example, a partnership or sole proprietorship might operate under the legal name of the business owner or owners. A corporation, limited liability company (LLC) or other type of business entity might operate under the name defined in the articles of incorporation or articles of organization.

But, sometimes you don't want to operate your business under your registered legal name. There are many reasons for this. For example, the legal name might be confusing, unrelated to your business, or no longer descriptive of your business. Or you just might want a new name without changing your incorporation or registration documents.

If you do business under a name different from the legal name of your business, that is called an 'assumed name', 'fictitious business name', or 'trade name'. Legally, it's called a doing business as name (DBA).

You can operate your business under as many DBA names as you want - there are no limits. But, each DBA name must be registered in the state where you operate. This is required because the public has a legal right to know that a particular person or legal entity is conducting a business under a name that differs from its legal name.

What a DBA is not

Registering a DBA does not excuse you from forming a legal business entity. In fact, if you don't form a legal business entity and simply register a DBA with your state, the law assumes you're operating your business as a sole proprietorship.

While many business operate this way, there are significant disadvantages to operating as a sole proprietorship. For example, you will not have any limited liability protection from lawsuits when you operate your business as a sole proprietorship. And you'll be directly responsible for your business's debts and obligations.

An LLC, limited partnership (LP), limited liability partnership (LLP), or corporation grants the owner or owners important limited liability protections and insulates owners from the debts and liabilities of the business.

Important things to consider when filing a DBA in Colorado

Here are important things you should consider when filing a DBA in Colorado:

Your legal business entity must be in good standing (you can get a certificate from your state or registration showing this).

You may need to get a money order or cashier's check to register a DBA. Not all states accept credit cards.

Your DBA cannot claim you have a corporation or LLC unless you actual business entity is a corporation or LLC.

Many states require that you notify people that you've registered a DBA by posting a notice with a local newspaper or publication.

Although you can identify your business in your registration documents under your Social Security Number, you should get an EIN (Employer Identification Number, also known as a Federal Tax ID Number) instead and use the EIN instead of your Social Security Number.

You may not operate under an assumed name unless you've registered that name as a DBA name in the state in which you're operating.

DBA registrations don't last forever. Check the specific state requirements carefully.

Most states require that you amend your DBA filing if your legal business information changes. This includes your business address, legal name, change in officers, etc.

Will I have to pay taxes if I register a Colorado DBA?

You do not pay taxes specifically for a DBA. Business taxes are determined by the business's structure and each business structure has its own tax rules.

The DBA is not a business structure so while you will be required to find taxes in accordance with your actual legal business structure, you will not have to file taxes specifically for the DBA.
