Colorado LLC vs DBA — Understanding the Difference
An LLC and a Trade Name (DBA) serve completely different purposes. An LLC creates a legal entity with liability protection. A DBA is simply a name registration — it provides zero liability protection. Here is when you need each.
For LLC formation details, see our formation guide.
Quick Comparison
| Feature | Colorado LLC | Trade Name |
|---|---|---|
| Liability protection | Yes — personal assets shielded | None |
| Formation cost | $50 | $20 (state level) |
| Ongoing cost | $25 (Periodic Report) | Renewal varies |
| Creates legal entity | Yes | No |
| Own bank account | Yes (under LLC name) | No (under your personal name) |
| Sign contracts | As the entity | As yourself |
| Tax return | May require separate return | No separate return |
| Legal standing to sue | Yes (as entity) | No (sue as individual) |
What Is a Trade Name?
A Trade Name — also called a "doing business as" name or trade name — registers an alternate operating name. In Colorado:
- Filed at the undefined level
- Cost: $20 (state level)
- Simply registers that "John Smith" is doing business as "Smith Marketing"
- Does NOT create a separate legal entity
- Does NOT provide any liability protection
- Typically expires and must be renewed
What Is an LLC?
Ready to get started?
Get StartedAn LLC (Limited Liability Company) is a legal entity separate from its owners under Colorado Revised Statutes Title 7, Article 80:
- Filed with the Colorado Secretary of State
- Cost: $50 (formation) + $25 (periodic report)
- Creates a separate legal person that can own property, sign contracts, sue and be sued
- Provides limited liability — business debts stay with the business
- Requires ongoing compliance (annual/biennial filings, registered agent)
When You Need an LLC (Not Just a DBA)
- Your business has liability risk (most businesses do)
- You want to protect personal assets
- You need to sign contracts without personal exposure
- You want business credit separate from personal credit
- You plan to grow, hire, or take on investors
When a DBA Is Sufficient
- You already HAVE an LLC and want it to operate under an alternate name
- Extremely low-risk activity with no contracts or liability exposure
- Temporary project name for an existing entity
Using Both Together
Ready to get started?
Get StartedMany businesses use BOTH:
- Form an LLC (for liability protection and legal structure)
- File a Trade Name under the LLC (for a marketing-friendly name)
Example: "XYZ Holdings LLC" files a DBA to do business as "Fresh Start Bakery"

FAQ
Can a DBA protect me from lawsuits?
No. A DBA provides zero liability protection. If your business is sued, creditors can pursue your personal assets because you ARE the business — there is no separate entity.
Do I need a DBA if I have an LLC?
Only if you want to operate under a name different from your LLC's legal name. If your LLC name IS your operating name, no DBA is needed.
Can I convert a DBA to an LLC?
A DBA cannot be "converted" — you form a new LLC and optionally cancel the DBA or file the DBA under the LLC. See our conversion guide.
What about taxes?
A DBA does not change your tax situation at all — you still file as a sole proprietor. An LLC can choose its tax classification (disregarded entity, partnership, S-corp, or C-corp).
