New Mexico DBA: Why There Is No Statewide Trade Name Filing and What to Do Instead
New Mexico DBA: Why There Is No Statewide Trade Name Filing and What to Do Instead
Search for “new mexico dba registration” and you will find sites that tell you to pay a state fee and file a trade name form with the Secretary of State. That is not how New Mexico works. The state has no statewide DBA, assumed name, or trade name registration for sole proprietors, general partnerships, LLCs, or corporations. There is no state fee for one because there is no filing to pay for. This guide explains what that means in practice, what you do instead, and which fees and filings still apply.
This article is general information, not legal or tax advice. If you operate under several names, have partners, or hold a license that controls how your name appears, talk with a New Mexico business attorney or a CPA before you rely on any of this.
The short answer
A DBA is the name you do business under when it differs from your legal name. In New Mexico, how you handle that name depends on how the business is organized:
- Sole proprietors and general partnerships simply use the name they chose. No state or county filing is required for the name itself, but you should search for conflicts first (see step one below).
- LLCs that will trade under a different name must state that name in the Articles of Organization. The $50 filing fee covers it, under NMSA 53-19-63.
- Corporations use their corporate name. The Secretary of State’s fictitious name application exists only for a foreign corporation whose true corporate name was rejected in New Mexico. Ordinary owners do not use it.
Cities and some counties may also require a local business registration filed under your trade name. That is a separate, local requirement, covered in step three below.
Why the confusion exists
Many states require an assumed name certificate filed with a state office or the county clerk, so owners who move from another state often assume New Mexico works the same way. Some websites describe a New Mexico trade name filing with a fee and a renewal cycle. That does not describe the current process. If a website quotes a state trade name fee, check the claim against the Secretary of State’s own pages before you pay anyone for a filing.
The practical difference matters. In a state with a DBA certificate, the certificate is your proof that you may use the name. In New Mexico, your proof comes from the entity filing (for an LLC or corporation), your Business Tax Identification Number, and any local registration. Building your records around those documents is the New Mexico approach.
What each structure files
| Structure | State name filing | Other filings and taxes |
|---|---|---|
| Sole proprietor | None | Free Business Tax Identification Number (BTIN) from the Taxation and Revenue Department if you do business in New Mexico |
| General partnership | None | BTIN from the Taxation and Revenue Department |
| LLC | Articles of Organization, $50, with any trade name stated in the articles | No annual or biennial report and no LLC franchise tax. BTIN required. Corporate tax applies only if the LLC elects to be taxed as a corporation. |
| Corporation | Articles of Incorporation, $100 | Corporate Report, $25, filed biennially. $50 annual corporate franchise tax reported on form CIT-1. Corporate income tax is a flat 5.9% for taxable years beginning on or after January 1, 2025. |
The structure you choose decides most of your filing list. A trade name by itself does not create a separate legal entity. If you want liability separation from your business activity, that is a structure decision, not a naming decision, and it belongs in a conversation with an attorney or CPA.
Step one: Search before you use the name
Because New Mexico has no trade name register, nothing at the state level shows who is already using a name. The Secretary of State’s business search at enterprise.sos.nm.gov/search covers registered entities such as LLCs, corporations, and partnerships. Search for the exact name and for close variants: different word order, singular and plural forms, and versions with or without words like “the,” “company,” or “services.”
A clean result there does not finish the search. Sole proprietors using a trade name do not appear in the entity database, so you also need to:
- Search the web, Google Business Profile listings, and social platforms for the same name in your industry and region.
- Search the federal trademark database at uspto.gov/trademarks. A federal trademark on a similar name can cause problems even though New Mexico has no filing for your trade name.
- Check the business registration lists for the city or county where you plan to operate.
If you plan to form an LLC, its legal name must be distinguishable from existing names on the New Mexico record, including LLCs, limited partnerships, corporations, foreign entities authorized in the state, and reserved names. A near match can get the filing rejected even when your trade name is different. You can reserve an LLC name for $20. The reservation lasts 120 days and cannot be renewed.
Step two: Get a Business Tax Identification Number
The Taxation and Revenue Department (TRD) issues the Business Tax Identification Number (BTIN), formerly called a CRS number, at no charge through tax.newmexico.gov. The BTIN is a tax registration, not a license. It is the number you use to report gross receipts tax. Check whether your activity must register on TRD’s who-must-register page.
New Mexico has no sales tax. The gross receipts tax is imposed on the seller instead. The state rate is 4.875%, and combined state and local rates run from 5.25% to 9.4375% under the schedule effective July 1, 2026 through June 30, 2027. Report under the BTIN for the business, whatever trade name appears on your invoices. Your local rate depends on where the sale happens, so confirm the rate for your location with TRD before you quote prices or set up your invoicing.
Step three: Register with your city or county
Cities and some counties charge their own flat annual business registration. As of 2026, these typically run about $30 to $40 a year, but amounts vary by jurisdiction, so confirm the current figure with the city or county where you operate. This is the closest thing New Mexico has to a local trade name filing, but it is a business registration, not a DBA. File it under your trade name, and get your BTIN first, because the local registration comes after the state tax number.
Step four: Check for activity licenses
New Mexico issues no general statewide business license. Some trades and professions do require a license from the Regulation and Licensing Department, and that license is separate from everything above. Ask the licensing agency whether it issues the license in your legal name, your trade name, or both. The name on the license should match the name you use with customers, so settle this before you print signs, vehicle wraps, or contracts.
Step five: Open the bank account and organize your records
Banks often ask for documents showing that you are entitled to use a trade name. Because New Mexico issues no trade name certificate, ask the bank which documents it accepts before you visit. For an LLC that stated its trade name in the Articles of Organization, the filed articles are the state record that shows the name. For a sole proprietor, the BTIN and your identification are the usual starting points. Keep a folder with the filed articles, your BTIN confirmation, your city or county registration, and your search results, so you can answer questions quickly.
Fee reference
| Item | Cost | Agency | Notes |
|---|---|---|---|
| State trade name (DBA) filing | No state fee | None | No filing exists for sole proprietors, general partnerships, LLCs, or corporations |
| LLC Articles of Organization | $50 | Secretary of State | Includes any trade name stated in the articles (NMSA 53-19-63) |
| Expedited LLC filing | $150 for same business day service when received before 2:00 p.m., or $100 for two business day service | Secretary of State | Paid separately and nonrefundable. Requests received after 2:00 p.m. move to the next business day. |
| LLC name reservation | $20 | Secretary of State | Holds the name for 120 days. Not renewable. |
| LLC annual or biennial report | None | Secretary of State | New Mexico LLCs file no report |
| Corporation Articles of Incorporation | $100 | Secretary of State | Formation filing for corporations |
| Corporate Report | $25, biennial | Secretary of State | First report within 30 days after the certificate of incorporation is issued |
| Corporate franchise tax | $50 a year | Taxation and Revenue Department | Reported on form CIT-1. Applies to corporations and to LLCs that elect corporate taxation, not to LLCs taxed as default pass-through entities. |
| Business Tax Identification Number | Free | Taxation and Revenue Department | Required for gross receipts tax reporting |
| City or county business registration | Typically about $30 to $40 a year as of 2026 | Local government | Confirm the current amount with the city or county. Filed under the trade name after you have your BTIN. |
Some of these figures may change, so check the agency pages before you budget. Pay the Secretary of State directly through its online system, and be wary of any third-party service that charges a separate “trade name” fee for a state filing that does not exist.
Common mistakes
- Paying a third-party service for a New Mexico DBA filing with the state.
- Leaving the trade name out of an LLC’s Articles of Organization when the LLC will trade under that name.
- Treating a clean Secretary of State search as proof that nobody uses the name.
- Skipping the city or county registration after forming the business.
- Choosing a name that is nearly identical to an existing LLC, which can get your LLC filing rejected.
- Assuming the $50 corporate franchise tax applies to every LLC. An LLC taxed as a default pass-through entity does not owe it.
When to get professional help
The steps above cover a single owner using one name. Get advice from a New Mexico business attorney or a CPA if you have multiple owners, plan to use one name across several entities, operate in a licensed profession, sell across state lines, or want to protect a brand with a trademark. A short consultation before you file is usually cheaper than correcting a rejected filing, a license problem, or a dispute over who owns a name.
