To file a DBA in New Mexico, register your trade name online with the Secretary of State through the filing portal at enterprise.sos.nm.gov. You’ll confirm the name is available, complete the Registration of Business Name form, and pay the filing fee electronically. The office no longer accepts paper filings for business applications, so the online portal is the only route.
Check That Your Name Is Available
Before you file anything, search the Secretary of State’s business database at enterprise.sos.nm.gov. Your proposed name must be distinguishable from every corporation, LLC, limited partnership, and trade name already on record. If a match or near-match comes up, choose something else before you spend time on the application.
A few naming rules will disqualify a name outright:
- Words like “Incorporated,” “LLC,” or “Limited Liability Company” and their abbreviations are reserved for businesses actually organized as those entity types. A sole proprietor or general partnership cannot include them.
- “Bank” and similar terms suggesting a banking operation are unlawful without authorization from the Financial Institutions Division. Under NMSA 1978 Section 58-1-76, unauthorized use can trigger legal action, and if you have a legitimate reason to use such a term you need a “no objection” letter from the division before you file.
- Words implying government affiliation or a professional license you don’t hold can draw enforcement under New Mexico’s unfair trade practices statutes.
Gather the Information the Form Requires
The Registration of Business Name form is governed by NMSA 1978 Chapter 57, Article 2. Have the following ready before you start:
- The full legal name of the individual owner, or the registered name of the corporation, LLC, or partnership that will own the trade name.
- The physical address and mailing address of the business.
- A description of the business activities you’ll conduct under the name.
- The date you began, or plan to begin, doing business in New Mexico under the trade name.
- For a general partnership, the names of all partners.
The owner or an authorized representative of the entity signs the form. Filling every field in correctly the first time keeps the Secretary of State from bouncing your application back for corrections.
Submit the Filing Online
Go to enterprise.sos.nm.gov, create an account, and follow the prompts to upload your completed form and pay the filing fee. Online submissions process faster than the old mail-in system, and you’ll get electronic confirmation once your filing is accepted. If you need in-person help, the Secretary of State’s office in Santa Fe is open on weekdays, though as of early 2026 in-person services are not available on Fridays.
Handle Taxes and Local Licenses Separately
Filing your trade name with the Secretary of State does not cover your tax or local licensing obligations. If you collect gross receipts tax or have employees, register with the New Mexico Taxation and Revenue Department for a Combined Reporting System (CRS) number. The department’s Business Tax Registration form (ACD-31015) has a field for your DBA name, which links the trade name to your tax account.
Sole proprietors who file a trade name do not need a new Employer Identification Number. The IRS treats the name change as an administrative update, so your existing EIN, or your Social Security Number if you have no employees, still works.
Many cities and counties require their own business license on top of the state filing. Albuquerque, for example, requires a business license and fee for each location inside city limits before you can operate. Check with the city or county clerk where you’ll be doing business.
Renewals, Amendments, and Cancellation
A New Mexico trade name registration lasts 10 years from the filing date under NMSA 1978 Section 57-2-5. Renew through the Secretary of State’s portal before the expiration date, confirm your information is still current, and pay the renewal fee. Miss the deadline and you lose the registration, and another business can claim the name.
If your address changes or ownership shifts during the 10-year period, file an amendment. Outdated records can interfere with service of process, meaning legal notices directed at your business may not reach you, and can also cause confusion on tax filings tied to the name.
If you stop using the name, file a cancellation or withdrawal. That keeps the public record clean and ends any lingering association between your legal identity and a brand you no longer use.
What a Trade Name Filing Does Not Do
A trade name creates a public record connecting your brand to the legal owner behind it. It is not a trademark, and filing does not give you exclusive rights to the name or stop a competitor from using something similar. For enforceable brand protection, you’d file a separate trademark registration with the New Mexico Secretary of State (minimum $50) or with the U.S. Patent and Trademark Office.
A trade name also does not create a separate legal entity. It gives you no liability protection. If you want the personal-asset shield, you need to form an LLC or corporation.
