New Mexico Workers Compensation Rules for Employers
New Mexico requires workers compensation at three employees, and at one in construction. Coverage rules, exclusions, injury deadlines, and penalties.
New Mexico Workers Compensation
The three-worker threshold, the construction exception, who is left out, the poster the state actually inspects, and the deadlines that start the moment someone gets hurt
A contractor outside Albuquerque told me he had been running clean for two years with one helper and no policy, because somebody had told him the rule kicked in at three employees. He had the number right and the exception wrong. Construction in New Mexico starts at one.
That conversation is the reason this page exists. New Mexico has a headcount rule, an industry rule that overrides it, an exclusion the Supreme Court struck down that still sits in the printed statute, and an executive employee opt-out that lowers your premium without lowering your headcount. Four moving parts, and a small employer only has to get one of them wrong to be uninsured.
What follows walks through those four rules, then where the policy comes from, the poster, the injury deadlines, the penalties, the steps to take after an injury, and the quarterly fee. It covers the New Mexico layer only, and everything here comes from the New Mexico Workers’ Compensation Administration (WCA), its rules in the New Mexico Administrative Code (NMAC), and the Taxation and Revenue Department.
When Coverage Becomes Mandatory
All New Mexico employers of three or more workers must carry workers compensation coverage. The Workers’ Compensation Administration states the threshold that plainly, and it comes from Section 52-1-6(A) of the New Mexico Statutes Annotated (NMSA 1978). Below three, and outside construction, the coverage is voluntary.
Construction runs on a separate rule, and headcount plays no part in it. Any employer engaged in activities that require a license under the Construction Industries Licensing Act must carry coverage regardless of the number of employees. That reaches out-of-state contractors doing work here, and the Construction Industries Division can suspend or revoke a license over a coverage lapse.
The WCA Employer Compliance Bureau adds a third line to its own list of who needs coverage: any business registered as a limited liability company or incorporated, with a note that some exceptions may apply. That phrasing is broader than the bare statute, and it exists because executive officers count as workers. If you run a small corporation or LLC in New Mexico, call the bureau before you conclude you are under the line.
Who Counts Toward Three
When you count heads toward three, the WCA employer guidebook says every person who does the work of the business entity may be considered an employee. That includes the owner if the owner works in the business, family members who are paid, and part-time, temporary, and seasonal workers. There is no hours floor and no seasonal carve-out.
Executive employees count too. Section 52-1-7 NMSA 1978 defines an executive employee as the chairman of the board, president, vice president, secretary, treasurer, or other executive officer who owns 10 percent or more of the corporation’s stock, or a 10 percent interest in an LLC. Partners in a limited partnership are counted as employees as well.
An executive employee may elect out of coverage for themselves by filing the election form with the insurer and the WCA director. That keeps their pay out of the premium base and out of the quarterly assessment fee, and it also means they collect nothing if they are hurt at work. The WCA is blunt about the arithmetic: a company with three employees including one exempted executive must still insure the other two.
Geography does not save you either. A company with three or more employees total and at least one of them working in New Mexico must carry a New Mexico policy, whether the employment is permanent, temporary, or transitory, and whether or not the workers live here. If your out-of-state carrier is licensed in New Mexico, it can add an endorsement; if it is not, you need a separate New Mexico policy.
Who Is Left Out
New Mexico’s exclusion list is short, and one entry on it is no longer enforceable. Section 52-1-6(A) still reads that the state’s Workers’ Compensation Act does not apply to employers of private domestic servants and farm and ranch laborers, but the New Mexico Supreme Court held the farm and ranch laborer exclusion unconstitutional on June 30, 2016.
| Worker category | How New Mexico treats it |
|---|---|
| Private domestic servants | Outside the Act under Section 52-1-6(A). The employer may elect in by filing a sworn statement with the WCA director or by buying a policy. |
| Farm and ranch laborers | The statutory exclusion was ruled unconstitutional by the New Mexico Supreme Court on June 30, 2016. Agricultural employers with three or more employees must carry coverage like anyone else. |
| Qualified real estate salespersons | Excepted from the definition of worker under Section 52-1-16. The person for whom the services are performed may elect coverage. |
| Independent contractors | Not employees, so they neither count toward three nor get covered. The WCA says there is no bright-line test and applies a right-of-control analysis case by case. |
| Sole proprietors and partners | A self-employed person or partner may elect into the Act. Partners in a limited partnership are counted as employees. |
| Corporate officers and LLC executives | An executive officer owning 10 percent or more of the stock, or a 10 percent LLC interest, may opt out of coverage. The opt-out never removes the person from the headcount. |
| Construction sole proprietors | May self-exempt using the Construction Industries Division sole proprietor election form, and are still counted toward the coverage trigger. |
| Family members | Paid family members are employees. The Supreme Court opinion treats children and relatives doing farm or ranch chores without wages as volunteers. |
| Part-time, temporary, and seasonal workers | All counted, with no minimum hours and no seasonal carve-out. |
| Federal employees under FECA | Outside the state Act, along with workers covered by other federal compensation programs. |
| Casual labor | Section 52-1-16 leaves out only a person whose employment is purely casual and not for the purpose of the employer’s trade or business. Anyone doing the regular work of the business can be counted. |
The agricultural line is the one to read twice. The WCA now answers the question directly on its own site: an agricultural employer with three or more employees must have coverage, and part-time and seasonal farm workers count toward that three. Reading the printed statute alone gets a New Mexico farm or dairy to exactly the wrong answer.
Independent contractor status is the other soft edge. The WCA says calling someone a contractor, signing a contract that says so, or issuing a 1099 does not settle it, and that the analysis turns on who has the right to control the details, means, and methods of the work. Getting that call wrong creates a coverage gap on top of the tax and wage exposure that misclassification already carries.
Where the Policy Comes From
New Mexico employers buy the policy from private commercial carriers. The state is not monopolistic and runs no state-owned insurance fund. The carriers are licensed by the New Mexico Office of the Superintendent of Insurance, which also approves the rates they charge. An agent places the policy for you, and the WCA points employers who have no agent toward the Independent Insurance Agents Association.
If the voluntary market will not quote you, the assigned risk pool will. The WCA employer guidebook describes pool coverage as meant for businesses with poor safety records or in high-risk industries that cannot get coverage elsewhere, and for many new small businesses. Servicing carriers designated by the Superintendent of Insurance provide it.
Coverage from the assigned risk pool carries extra charges. Everyone in the pool pays a surcharge of 10 percent on the manual premium, the premium figured at the standard published rates before adjustments, and a severity-based adjustment can be added on top.
Self-insurance exists, and the bar is set where small businesses do not reach it. Under 11.4.8 NMAC an individual self-insurer needs a tangible net worth of at least $2,500,000, at least three years in business, an approved security of not less than $200,000, and specific excess insurance with a retention of $250,000 or less per occurrence.
The self-insurance application carries a $150 non-refundable filing fee, and the WCA director acts on a completed application within 90 days. Group self-insurance, governed by 11.4.9 NMAC, adds what the WCA calls joint and several liability: every member can be responsible for the group’s losses if the group becomes insolvent.
One New Mexico feature deserves a mention because it surprises carriers from out of state. New Mexico courts have required workers compensation insurers to reimburse medical cannabis prescribed for a work injury, and the WCA worker guidebook describes the worker paying at the dispensary and being reimbursed at a rate set by law. Raise it with your carrier before a claim rather than during one.
The Poster and the Accident Forms
New Mexico requires a posted notice, not a new-hire handout. Every covered employer displays the WCA workers compensation poster where employees can read it, and the poster is incomplete without a supply of Notice of Accident forms attached to it or next to it. The poster says this in its own footer: the poster without the forms does not comply with the law.
The current version was mandatory for all New Mexico businesses by December 31, 2025, and carries English and Spanish on a single sheet. You fill in the blank box yourself with the name, phone number, and address of your insurer or claims representative. Posters and forms are free from the agency, in print or as downloads.
Skipping the forms is the expensive half of the mistake. The WCA employer guidebook is explicit that when the poster and the accident forms are not displayed together, the worker’s obligation to notify you within 15 days stretches to 60 days, and non-compliance may draw a fine as well. Investigating a two-month-old injury is a different job from investigating a two-week-old one.
Keep the forms somewhere a worker can take one without asking permission. The WCA states that storing them in a supervisor’s desk defeats the purpose of the law, since the point is free and easy access. A bulletin board in the break room, next to the poster, is the arrangement the agency describes.
Injury Reporting Deadlines
Three deadlines run from a single New Mexico injury, and if you carry insurance only one of them is yours. The worker gives written notice within 15 days, you notify the insurer within 72 hours, and your claims administrator files the first report of injury with the WCA within 10 days when the injury costs more than seven days of work.
| Trigger | Who acts | Deadline |
|---|---|---|
| Worker knows the injury is work related | Worker | Written notice to the employer within 15 days |
| Poster and Notice of Accident forms are not displayed together | Worker | The 15-day window stretches to 60 days |
| Injury itself prevents the worker from giving notice | Worker | Up to 60 days |
| Employer gets actual knowledge or is handed the form | Employer | Report to the insurer or claims administrator within 72 hours |
| Injury causes more than seven cumulative days of lost time | Claims administrator (the employer only if self-insured or uninsured) | File the first report of injury with the WCA within 10 days of notification |
| Employer or insurer refuses to pay benefits | Worker | File a claim with the WCA within one year |
| Calendar quarter ends | Employer | Pay the assessment fee on or before the 25th of the following month |
| Policy is issued or renewed at $15,000 or more in premium | Employer | Send proof of the annual safety inspection within 60 days |
The 72-hour clock is the one employers miss, because it is short and it starts early. Rule 11.4.3.13 NMAC requires the employer to report every accident to the insurer within 72 hours. A self-insured employer reports to its claims administrator instead.
The 72-hour clock starts at whichever comes first: your actual knowledge of the accident, or a worker presenting you with a Notice of Accident form. The rule adds that you report whether or not you consider the claim valid.
The first report of injury is due when an injury causes more than seven cumulative days of lost time. Rule 11.4.2.8 NMAC sets that trigger and gives 10 days from notification to file, and the WCA notes that the missed days do not have to be consecutive.
The first report is filed electronically with the WCA by your claims administrator, meaning the insurer or its third-party administrator. If you are self-insured or uninsured, you file it yourself. Either way, copies go to the injured worker and to you.
One deadline runs the other way and is worth knowing when a claim goes quiet. Under Section 52-1-31 NMSA 1978 the worker has one year to file a claim with the WCA, counted from the employer or insurer failing or refusing to pay compensation. That clock is tolled, meaning paused, for up to a year while the worker stays employed by the same employer.
What Going Without Coverage Costs
The WCA describes penalties of up to $1,000 per day for each day a business is in violation of the mandatory coverage requirement, and it can seek a temporary restraining order preventing the business from operating until a policy is in place. Section 52-1-61 NMSA 1978 sets the underlying range at not less than $25 and not more than $1,000 per occurrence.
Enforcement starts softer than that sounds. A compliance officer contacts the business and allows time to buy a policy, and the WCA says it always prefers coverage over prosecution. Refuse, and the file moves from the Employer Compliance Bureau to the Enforcement Bureau for administrative prosecution, with the owner summoned to a hearing at the agency.
The uninsured employer also loses the protection that makes workers compensation worth buying. An employee injured at a business with no coverage may sue in district court for compensatory and punitive damages, fees, and costs, and the WCA notes there are no defined limits on that award. There is no benefit schedule capping what a jury can do.
Two smaller penalties round out the picture. Retaliating against a worker for seeking benefits carries a civil penalty of up to $5,000 under Section 52-1-28.2 NMSA 1978, paid by the employer rather than the carrier. Employers paying $15,000 or more in annual premium who skip the required safety inspection can face a penalty of up to $5,000.
New Mexico’s coverage enforcement reads as civil and administrative rather than criminal. WCA materials attach criminal prosecution to fraud and bad faith in the claims process, not to the coverage lapse itself, so the exposure for an uninsured New Mexico employer is fines, an injunction, tort liability, and reimbursement.
What to Do When Someone Gets Hurt
Run the same sequence every time, because the order protects both the worker and the file. Care first, form second, insurer third, agency fourth.
Steps two and three are where documentation quietly decides claims. A signed and dated accident form and a written provider election, both kept with the employee record, answer most of what an adjuster or a judge asks months later. Holding that paper trail in one place is exactly the kind of recurring obligation FirstHR was built for in a business with no dedicated HR person.
The Quarterly Assessment Fee
New Mexico charges a separate quarterly fee on top of the premium, and it buys no insurance at all. The WCA puts the workers compensation assessment fee at $4.80 per covered employee per calendar quarter, split $2.55 from the employer and $2.25 taken as a payroll deduction from the worker, counted on employees working on the last working day of the quarter.
The Taxation and Revenue Department collects it, not the WCA, and publishes the same split with its schedule: $2.55 and $2.25 from July 1, 2025 through June 30, 2028, then $2.68 and $2.38 from July 1, 2028, then $2.80 and $2.50 from July 1, 2033.
The fee has a fixed due date and a required filing method. Under Section 52-5-19(C) NMSA 1978, as amended effective January 1, 2026, the fee is due on or before the 25th day of the month following the end of the quarter. The department requires electronic filing on Form TRD-41431 for filing periods beginning January 1, 2026.
Three practical notes. New businesses register with the department for a business tax identification number before the first filing. Executive employees who elected out of coverage do not owe the fee. And the money funds the agency and the Uninsured Employers’ Fund, which is why a compliant employer is partly paying for the consequences of an uninsured one.
Frequently Asked Questions
How many employees before New Mexico requires workers compensation?
Three or more workers, under Section 52-1-6(A) NMSA 1978. Construction overrides that entirely: any employer licensed under the Construction Industries Licensing Act needs coverage from the first employee, including out-of-state contractors. The WCA Employer Compliance Bureau also lists LLCs and incorporated businesses among those needing coverage, with exceptions, so verify a small corporation with the bureau.
Do owners and corporate officers count toward the three?
Yes. Executive employees are included in the headcount under Section 52-1-7, meaning an officer owning 10 percent or more of the stock or LLC interest. Such a person may elect out of coverage for themselves, which removes their pay from the premium and the assessment fee, but the WCA still counts them. Two workers plus one exempted officer means the other two must be insured.
Are farm and ranch workers covered?
Yes. The statutory exclusion for farm and ranch laborers was ruled unconstitutional by the New Mexico Supreme Court on June 30, 2016, and the WCA now applies the ordinary three-employee rule to agricultural employers. Part-time and seasonal farm workers count, paid family members count, and unpaid relatives or neighbors helping with chores are treated as volunteers.
Where do I buy the policy?
From a private carrier licensed by the New Mexico Office of the Superintendent of Insurance. New Mexico has no state insurance fund. Businesses that cannot get a voluntary market quote use the assigned risk pool, which adds a 10 percent surcharge on the manual premium. Self-insurance requires a $2,500,000 tangible net worth and written approval from the WCA director.
What has to be posted, and does a new hire get anything?
The WCA poster, with Notice of Accident forms displayed alongside it, and with your insurer or claims representative filled into the blank box. There is no separate new-hire pamphlet requirement in New Mexico. The updated poster became mandatory for all businesses on December 31, 2025 and carries English and Spanish on one sheet.
How fast must an injury be reported?
The worker has 15 days to give you written notice, stretched to 60 days if you failed to post the accident forms with the poster or if the injury prevented notice. You have 72 hours to tell your insurer, from the earlier of actual knowledge or receipt of the form. The first report of injury goes to the WCA within 10 days when lost time exceeds seven cumulative days.
What are the penalties for no coverage?
Up to $1,000 per day of violation, plus a possible temporary restraining order closing the business until it is insured. An injured worker may sue in district court for compensatory and punitive damages with no defined limit, and may claim from the Uninsured Employers’ Fund, which then bills you for everything it paid plus a 15 to 50 percent penalty, interest, and fees.
How much is the quarterly assessment fee?
$4.80 per covered employee per quarter, made up of $2.55 from the employer and $2.25 withheld from the worker, counted on the last working day of the quarter. You file and pay it electronically with the Taxation and Revenue Department by the 25th of the month after the quarter ends. It is an administrative fee that funds the WCA and the Uninsured Employers’ Fund, and it provides no coverage of its own.
