Santa Fe County Business License: Home Occupation Impact Tiers and Unincorporated Area Rules
Santa Fe County Business License: Home Occupation Impact Tiers and Unincorporated Area Rules
Running a business from your home in Santa Fe County means following two sets of rules. New Mexico state filings apply everywhere in the state. County rules apply only if your property sits outside the cities. Santa Fe County licenses businesses in the unincorporated area, meaning land outside the cities of Santa Fe, Edgewood and Espanola. If your property is inside one of those cities, the city's rules apply instead.
Inside the unincorporated area, the county does not treat every home business the same. Its Sustainable Land Development Code sorts home occupations into impact tiers based on how many employees you have, how many people visit the property, and how much of the floor area the business uses. The tier you fall into decides which approval you need: a business registration, a development permit or a conditional use permit.
Step one: state filings come first
New Mexico has no general statewide business license. The state's business navigator lists three universal steps: register your legal entity with the Secretary of State, obtain tax ID numbers through the Taxation and Revenue Department (TRD), and obtain any activity-specific license from the Regulation and Licensing Department. Most home businesses only need the first two. Cities and counties may add their own local registration on top of those steps.
Your entity choice determines the state paperwork:
- LLC: The Articles of Organization cost $50 and are filed online through the SOS Enterprise Business Filing System. The LLC name must contain "limited liability company," "limited company," or an abbreviation such as LLC, L.L.C., L.C. or LC. An LLC files no annual or biennial report with the Secretary of State. If you will trade under a name other than the LLC name, state that trade name in the Articles of Organization. New Mexico has no statewide DBA or assumed-name registration, so the Articles are the only state filing where a trade name goes. Expedited filing costs $150 for same business day service when received before 2:00 p.m., or $100 for two business day service, paid separately and nonrefundable. Name reservation costs $20 and lasts 120 days, and it cannot be renewed.
- Corporation: The Articles of Incorporation carry a $100 filing fee. The corporation files a Corporate Report at $25. The first report is due within 30 days after the certificate of incorporation is issued, and later reports are due biennially. The corporation also owes a $50 annual corporate franchise tax, reported on form CIT-1.
Every LLC must also keep a registered office and a registered agent in New Mexico. The registered office can be your home address, and the agent can be a New Mexico resident individual or an entity with a New Mexico place of business at that address. Changing the registered office or agent costs $20 for an LLC and $25 for a corporation.
Sole proprietors and general partnerships should know that New Mexico has no assumed-name filing for them either. Your home business name is not registered with the state, which catches many first-time operators off guard.
Where the county license applies
Before you apply, confirm that your parcel is outside the city limits. A mailing address does not always reveal the jurisdiction, and the cities of Santa Fe, Edgewood and Espanola each have their own registration rules. Ask county staff to confirm the parcel status in writing if the answer is not clear from your deed or the county's maps.
The three home occupation impact tiers
The code sets three tiers. The limits below are the figures that separate one tier from the next.
| Tier | Approval required | Non-resident employees | Client or visitor trips | Share of floor area |
|---|---|---|---|---|
| No Impact | Business registration | 1 | No client visits | Up to 25% |
| Low Impact | Development permit | 3 | 4 a day | 35% |
| Medium Impact | Conditional use permit | 5 | 12 a day | 50% |
No Impact is the lightest path. It allows one non-resident employee, no client visits and up to a quarter of the floor area. Low Impact requires a development permit, and Medium Impact requires a conditional use permit, which is the more involved approval. Processing times for these permits are set by the county, so ask county staff for a current timeline before you sign a lease or sign a contract with a customer.
Confirm with county staff how employees, visits and floor area are counted. A business that stays within every No Impact limit at the same time can use the lightest approval. If you exceed any one limit, expect to fall into the next tier. Do not plan around the No Impact limits until you have checked how the county measures each one.
Application requirements: letter of intent and fire inspection
Applications require a letter of intent and a Fire Prevention inspection. The letter should describe the business in plain terms: what you sell or do, the number of employees, the expected visits per day, and the floor area you will use. Write it so the details match the tier you are applying for. A letter that understates visits or employees can send your application back for correction or into the wrong tier.
Schedule the Fire Prevention inspection early, because your approval may wait on it. Ask the county which conditions the inspector checks and whether a re-inspection is needed if the first one fails. Ask the county whether stored chemicals, fuel or heavy equipment raise extra questions.
Fees: confirm the current county schedule
The county fee schedule sets the fees for business registrations, development permits and conditional use permits. Pull the current schedule from Santa Fe County before budgeting. Your total cost will include the state filing you chose, the county fee for your tier and any fire inspection charge. Ask county staff whether the inspection carries a separate fee, and whether the fee is paid at application or at approval.
County living wage
Santa Fe County has its own living wage ordinance, separate from the City of Santa Fe's. Effective March 1, 2026, the county living wage is $15.40 an hour, with a $4.62 tipped base. It applies to businesses that must hold a county business license. Whether your home business is one of them depends on how the county classifies your tier and activity, so check with the county before you hire anyone or set wages. Do not assume the city's rate or rules apply to a county address.
Short-term rentals
Short-term rentals fall under Ordinance 2022-07, as amended in January 2024. The ordinance splits rentals into two groups:
- Owner-occupied units register as a business.
- Non-owner-occupied dwellings each need their own business license, valid for one year.
If you own a guest house, a casita and a main residence, and you live in only one of them, the other two each need a separate license. Put each renewal date on your calendar when the license is issued, because a one-year license lapses on its own. Confirm the current registration process and fees with the county before you list a property for rent.
Tax registrations: BTIN and the gross receipts tax
The Business Tax Identification Number (BTIN), formerly called the CRS number, is issued by TRD at no charge. It is a tax registration, not a license. Having a BTIN does not mean the county has approved your home business, and the county still needs its own approval. Register through TRD at https://www.tax.newmexico.gov/businesses/who-must-register-a-business/.
New Mexico has no sales tax. Instead, the gross receipts tax is imposed on the seller. 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. If you sell taxable goods or services from your home, you will report gross receipts to TRD. Confirm with TRD or a CPA which of your receipts are taxable.
An LLC taxed as a default pass-through does not owe the $50 corporate franchise tax. An LLC that elects to be taxed as a corporation files form CIT-1 and owes that tax.
Common mistakes to avoid
- Looking for a state DBA filing. New Mexico has none for sole proprietors, partnerships, LLCs or corporations.
- Treating the BTIN as county approval. It is a tax registration only.
- Calling the business a "home office" and skipping the impact tier analysis. A home office that sees clients or staff may fall into a higher tier.
- Hiring a second worker under No Impact without checking the one non-resident employee limit.
- Counting several rental properties as one license. Each non-owner-occupied dwelling needs its own.
- Missing a corporation's first Corporate Report deadline, which runs 30 days from the certificate of incorporation.
