How to Start a Solar Installation Business in New Mexico: Which CID License Applies

Most solar installers in New Mexico ask the license question first, and it is the one most often answered wrong. The state does not issue a general business license, so your setup work is about the legal entity, a free tax registration, and the contractor license that matches the work you plan to bid. For photovoltaic (PV) systems, the Construction Industries Division (CID) of the Regulation and Licensing Department sets the rules in 14.5.2.10 NMAC. Some of those rules differ from what installers expect. This guide covers the steps in the order you should take them and flags every figure you need to confirm with the agency. This article is informational, not legal or tax advice.

What You Need Before You Start

Gather these items before you file anything:

• A decision on your legal entity. Most solar businesses form an LLC or a corporation, and the entity controls which state filings you make.
• An account on the SOS Enterprise Business Filing System at https://enterprise.sos.nm.gov/
• A Business Tax Identification Number (BTIN) from the New Mexico Taxation and Revenue Department (TRD), which is free
• The current CID license application, fee schedule, bonding rules and exam information from https://rld.nm.gov/construction-industries
• Names and journeyman certificate numbers for every person who will do PV electrical work, or proof that an apprentice will work under direct supervision of a journeyman
• A list of city and county registration requirements for every place you plan to work
• A plan for structural review on roof work, including a New Mexico licensed professional engineer when the thresholds in Step 6 apply
• A licensed New Mexico electrical contractor who will pull the electrical permit if your own license does not cover that role

Step 1: Form the Legal Entity

Form your entity first. Your LLC or corporation name will appear on your CID application, your tax registration and every contract you sign.

An LLC files Articles of Organization for $50 through the SOS Enterprise system at https://enterprise.sos.nm.gov/. Search the name first at https://enterprise.sos.nm.gov/search. The name must include limited liability company, limited company, or an abbreviation such as LLC, L.C. or LC, and it must be distinguishable from existing names on file. If you will trade under a different name, state that name in the articles of organization. New Mexico has no statewide DBA or assumed-name registration, so there is no separate state filing for your trade name.

You can reserve a name for $20. The reservation lasts 120 days and cannot be renewed. Expedited filing costs $150 for same business day service if received before 2:00 p.m. (next business day if received later), or $100 for two business day service. Both expedite fees are paid separately and are nonrefundable. The Secretary of State does not publish a standard turnaround, so watch your email for approval, rejection or a correction request.

Entity	State formation filing	Ongoing state filing or tax
LLC	Articles of Organization, $50	No annual or biennial report and no LLC franchise tax. An LLC taxed as a default pass-through does not owe the $50 corporate franchise tax. An LLC that elects corporate taxation files form CIT-1 and owes the $50 annual franchise tax.
Corporation	Articles of Incorporation, $100	Corporate Report, $25, first due within 30 days after the certificate of incorporation is issued, then biennially on or before the fifteenth day of the fourth month after the taxable year ends. Also a $50 annual corporate franchise tax, reported on form CIT-1.

Changing your registered office or agent later costs $20 for an LLC and $25 for a corporation. Every New Mexico LLC must maintain a registered office and a registered agent for service of process.

Step 2: Get Your Business Tax Identification Number

Register with TRD at https://www.tax.newmexico.gov/ for a Business Tax Identification Number. The BTIN is the renamed version of the old CRS number, and it costs nothing. It is a tax registration, not a license, so it does not authorize you to bid or perform solar work.

New Mexico has no sales tax. The gross receipts tax applies to the seller instead. The state gross receipts tax rate is 4.875%. Combined state and local rates run from 5.25% to 9.4375% under the schedule effective July 1, 2026 through June 30, 2027. The rate depends on where the job is located, so confirm the rate for each site. Ask your CPA how gross receipts tax should appear in your pricing and contracts.

Step 3: Check City and County Registration

Cities and some counties require their own flat annual business registration on top of the state filings. The amounts differ by jurisdiction. Contact the city or county clerk where your office sits and each place you plan to work. Do not put a local fee into a customer bid until you have confirmed it.

Step 4: Match Your Scope to the Right CID Classification

This step decides whether you can bid PV work at all. Under 14.5.2.10 NMAC, anyone bidding or contracting a solar PV electric system must hold a CID license in one of the classifications below, as applicable to the work:

• EE-98, EL-1 or ER-1: the electrical classifications the rule names for solar PV electrical systems. Confirm with CID which one matches the scope you plan to bid.
• GB-98: authorized in some cases. Confirm with CID whether your work qualifies.
• GB-02: allowed where structural modifications are needed, such as reinforcing roof framing. Confirm with CID how it applies to your scope.

There is no GS-3 solar classification. If a supplier or a training course tells you to apply for GS-3 for solar, you are chasing a classification the rules do not provide. Ask CID for written confirmation of the classification you need before you buy vehicles, sign a lease or print marketing materials that promise solar installation.

Step 5: Qualify Your Workers

Your contractor license does not cover the people on the roof. The individuals doing PV electrical work must hold a journeyman certificate in the matching classification: EE-98J, EL-1J or ER-1J. An apprentice may do this work only under the direct supervision of a journeyman. A helper without a certificate who wires panels on their own is out of compliance, even if your company holds the right license.

Keep a file for each worker with the certificate type, certificate number and a status check with CID. Verify every crew member before the job starts, not after the inspection fails.

Step 6: Plan the Structural Review

Panels add load to a roof that may not have been designed for it. Under the rule, a New Mexico licensed professional engineer must perform a structural analysis when any of these conditions applies:

• The added load exceeds 5 pounds per square foot.
• A point load exceeds 45 pounds.
• The load on a single truss, rafter or joist exceeds 200 pounds.
• The mounting is a unique design.

Build the engineer's fee and lead time into your bid. Do not assume one standard rack layout fits every roof, especially older homes and commercial buildings with unusual framing.

Step 7: Confirm Fees, Bonding and Exam Details With CID

CID sets the license fees, bonding requirements and exam details for each classification. Check the current application, fee schedule and bonding rules at https://rld.nm.gov/construction-industries, and confirm the exam requirements for your classification before you pay anything. Budget for the license, the bond and the exam in your startup costs, and ask CID to confirm the amounts in writing for your classification.

Step 8: Plan Electrical Permitting

The electrical permit for a PV system goes to a licensed New Mexico electrical contractor. Decide before you sign a contract who holds that role on each job. If your company does not hold that license, put the permit and inspection responsibilities in a written agreement with the contractor. Confirm with CID and your local permitting office how the permit should be pulled for your scope of work.

Step 9: Check Solar Tax Credits

The New Mexico solar market development tax credit is administered by TRD at https://www.tax.newmexico.gov/. Confirm whether it is currently available, what it is worth and how it applies to your customers before you show a credit amount in a proposal. Federal credits are governed by the Internal Revenue Service at https://www.irs.gov. Both change often, so check the current rules before you quote a net price. Do not promise a customer a specific credit amount.

Expected Results

If you complete these steps in order, you may be in a position to bid and contract PV work in New Mexico under the correct classification, with qualified workers and permits pulled through a licensed contractor. Timing varies. The Secretary of State publishes no standard turnaround, CID processing time and exam scheduling should be confirmed with the agency, and a job that needs an engineer's review can lengthen its schedule. Treat this list as a checklist to verify, not a guaranteed timeline.

Tips and Common Mistakes to Avoid

• Bidding before the classification is confirmed. Do not send a solar proposal or sign a contract until the classification you need is confirmed for your business.
• Searching for a GS-3 solar license. The rules name no GS-3 solar classification.
• Treating the BTIN or the LLC filing as a license. Both are registrations. Neither authorizes solar work.
• Letting an uncertified helper do PV wiring. Use a journeyman or an apprentice under direct supervision.
• Skipping the structural check. Check the 5 pounds per square foot and 45 pound point load thresholds against your racking plan.
• Looking for a state DBA filing. New Mexico has none. Name the trade name in your articles of organization instead.
• Assuming an LLC owes the $50 corporate franchise tax. An LLC taxed as a default pass-through does not owe it.
• Quoting credit amounts from a blog post. Check TRD and the IRS before you put any credit figure in front of a customer.
