How to Change Your LLC Name in Colorado (2026)
To change your LLC's name in Colorado, you file Articles of Amendment with the Colorado Secretary of State. The fee is $25, and you can only file online. Once you submit payment, the change is real time and shows on your record right away.
Your new name replaces the old one across your state records, but your LLC's EIN, formation date and Colorado ID number stay exactly the same. You don't need a new EIN just because you picked a different name.
Quick Summary
- Search the state's business database before you file. A name that's too similar to one already on record can't be filed.
- Get member approval before you file. Your operating agreement sets the vote threshold you'll need to clear.
- Give yourself a week or two to finish every step. You'll still need time to update licenses, contracts and your bank account.

How to change your Colorado LLC name
Follow these three steps to change your LLC's name with the Colorado Secretary of State, from checking availability to filing the amendment that makes it official. The steps below walk through changing an LLC's name in Colorado.
Step 1: Confirm the new name is available
Search the Secretary of State's business database to check whether your new name is already taken. Your name must include a term like "LLC" or "limited liability company" to meet Colorado's requirements.
These are the same naming rules that apply when you start an LLC in Colorado, and your new name must be distinguishable from other names already on file.
If you're not ready to file yet, reserve the name for 120 days [1] for a $25 fee. This keeps the name off-limits to other filers while you finish the paperwork.
Step 2: Get member approval
Check your LLC's operating agreement for its vote threshold, then hold a meeting to approve the new name at that bar.
If you're a single-member LLC, you can approve the change yourself and skip the formal vote. Write down the decision and the new name for your own records.
Step 3: File the Articles of Amendment
File Articles of Amendment through the Secretary of State's online filing system. Colorado accepts this document only through that online system, so there's no mail, fax or in-person option. The form asks for your LLC's ID number, current name and new name.
Once it's filed, the confirmation and a copy of the amendment are available to view and print from your account. Your filing posts to your record in real time, right after your payment clears [2].
After your name change is approved: what to update
Once the state approves your amendment, update these records so your new business name matches everywhere it appears in your paperwork.
- State and local licenses: Update any Colorado business licenses or permits tied to your old name.
- The IRS: You don't need a new EIN. If your LLC files Form 1065, check the name change box on your next return [3]. Single-member LLCs write a letter to the IRS address where they filed their last return.
- Give your bank a copy of the filed amendment so it can update your business accounts.
- Notify clients, vendors and contract partners who still have your old name on file.
- Revise your operating agreement so it reflects the new name and matches your state filing.
- Update your registered agent information in Colorado so their file matches your new name too. Need a new provider? Compare a Colorado registered agent service before you switch.
Alternatives to a formal name change
Sometimes a full name change isn't what you need. Colorado also lets you operate under a different name or fix a filing error without amending your Articles of Organization.
1. DBA / trade name
You can register a trade name, often called a DBA, with the Colorado Secretary of State for $20. This lets you operate and advertise under a different name while your LLC's legal name stays the same. Colorado files these at the state level.
2. Statement of Correction
If your Articles of Organization already show the right name but it was filed with a typo, file a Statement of Correction Correcting the Entity Name instead. It costs $10 online and fixes clerical mistakes rather than a deliberate name change.
