Hiring your first employee in New Mexico

What do you have to register for before your first payroll?

One registration with the Taxation and Revenue Department gives you a New Mexico Business Tax Identification Number, and that single number covers gross receipts tax, compensating tax and wage withholding, so there is no second sign-up for payroll withholding. Two things sit outside it. Unemployment insurance is a separate account with the Department of Workforce Solutions, and the order matters: the Taxation and Revenue Department says an employer covered by the Workers' Compensation Act must get its employer account number from Workforce Solutions before it can open the workers compensation assessment fee account on the Taxation and Revenue side. Workers compensation insurance itself is bought from a private carrier and is not a state account at all.

Does New Mexico require income tax withholding?

Yes. You register with the New Mexico Taxation and Revenue Department, before your first new mexico payroll, by applying for a new mexico business tax identification number through taxpayer access point at tap.state.nm.us.

The trigger is simple: if you withhold federal income tax from an employee's wages, you withhold New Mexico tax too. Three details catch out-of-state employers. There is no New Mexico W-4, so employees fill in a copy of the federal W-4 marked for New Mexico state withholding only and you keep it on file. You do not have to withhold New Mexico tax from a nonresident employee who works in the state for 15 or fewer days in a calendar year, which matters if you send people in for short stints. And your filing frequency is set by size: a business averaging more than $200 a month of combined gross receipts and withholding tax liability over any twelve month period must file monthly, and only businesses below that may elect quarterly or semiannual. Starting with the quarter beginning 1 January 2026 every employer also has to file Form TRD-41431 electronically each quarter, due the 25th of the month after the quarter closes, reporting each employee's gross wages and the state tax withheld; the same return carries the workers compensation assessment fee that used to be the WC-1. The account does not close itself when you stop paying wages, so cancel the number on Form ACD-31015 rather than going quiet.

What unemployment insurance does New Mexico charge a new employer?

A new New Mexico employer pays 1% on the first $34,800 each employee earns, so roughly $348 per employee in the first year. A new employer pays the greater of 1.0% or its industry's average rate, assigned from the first two digits of its NAICS code, and keeps that rate until it has two years of experience rating. For 2026 most sectors sit exactly at the 1.00% floor, including retail, wholesale, manufacturing, finance, professional and technical services, health care, accommodation and food services. The ones that do not are worth checking before you budget: construction 1.21%, agriculture 1.19%, administrative and waste services 1.19%, transportation and warehousing 1.15% and information 1.08%. Tax is owed on the first $34,800 of each employee's wages in 2026, up from $33,200 in 2025, so the base moves every January. The registration trigger is low: a non-agricultural employer must file once its New Mexico payroll reaches $450 in any calendar quarter, or once it has one or more workers in any part of a week in each of 20 weeks in a calendar year. Agricultural employers use $20,000 a quarter or ten workers in 20 weeks, domestic employers $1,000 a quarter. Quarterly reports are due the last day of the month after each quarter. Once you are experience rated the rate is your benefit ratio multiplied by a reserve factor, 3.6361 for 2026, multiplied by an experience history factor, with a floor of 0.33% and a cap of 5.4%, plus an excess claims premium of up to a further 1% for employers whose calculated rate would have exceeded 5.4%. One practical note: the department's web address moved from dws.state.nm.us to dws.nm.gov, so older bookmarks and vendor instructions may point at a dead host.

Do you need workers compensation insurance in New Mexico?

Yes, once you reach 3 employees. Below that New Mexico does not require it, but read the counting rules before assuming you are under the line, because who counts is rarely obvious.

• every private employer with three or more workers, counting part-time and seasonal workers and paid family members
• anyone actively engaged in work that has to be licensed under the Construction Industries Licensing Act, from the first worker, with no headcount at all
• agricultural employers with three or more workers, since the New Mexico Supreme Court struck down the farm and ranch laborer exclusion in 2016

Three is the number, and the counting rules are what surprise people. Part-time, seasonal and paid family members all count. So do owners: an executive employee of a corporation or an LLC, meaning an officer or member holding 10 percent or more, counts toward the three even if that person is then excluded from the policy, and limited partners count too. Construction is the big exception and it has no threshold at all, so a licensed contractor needs coverage from its first worker. Read one page on the Administration's own site with care: the Employer Compliance Bureau lists any business registered as a Limited Liability Company or incorporated alongside the three worker rule, which reads as if forming an LLC alone triggers coverage. Section 52-1-2 NMSA 1978 and the Administration's own FAQ both put the requirement at three or more workers, with owners counted in that three, so treat three as the number and take the LLC line as shorthand for the executive employee counting rule. Going without coverage when you need it can cost up to $1,000 a day. Separately, every covered employer pays a quarterly assessment fee of $4.80 per covered employee working on the last day of the quarter, made up of $2.55 from the employer and $2.25 withheld from the worker, and that fee goes to the Taxation and Revenue Department on Form TRD-41431. Paying it is not insurance and does not make you covered; you still have to buy a policy.

How quickly must you report a new hire in New Mexico?

Within 20 days of the date of hire, rehire or return to work, or in two monthly transmissions no more than 16 days apart if you report electronically. Reports go to the New Mexico New Hire Directory.

This report goes to the New Mexico New Hire Directory, which is neither the Taxation and Revenue Department nor your unemployment insurance account, so it is easy to skip when you set up payroll. You report anyone who lives or works in New Mexico and whom you expect to pay, full-time, part-time or temporary, and you report them even if they work a single day and leave before you got round to filing. A returning worker counts as a new hire again once they have been separated, laid off, furloughed or on unpaid leave for 60 days or more, which sweeps in teachers, substitutes and seasonal staff. Temporary agencies report a worker once rather than at each client assignment. You need your FEIN, your business name and payroll address, and the employee's name, address, Social Security number and hire date.

Does New Mexico have paid family leave or state disability insurance?

No. New Mexico runs no state paid family leave fund and no state disability insurance, so there is no payroll deduction of that kind and no extra account to open.

New Mexico runs no state disability insurance fund and no paid family and medical leave programme, so nothing is deducted from a New Mexico paycheck for one and you owe no employer premium. This is worth checking carefully because a paid family and medical leave bill has been introduced repeatedly and search results quote its text as though it were law. It is not. In the 2025 regular session House Bill 11, titled Paid Family and Medical Leave Act, passed the House 38 to 31 on 28 February 2025, was reported out of a Senate committee on 11 March 2025, and then had action postponed indefinitely, which killed it. The Department of Workforce Solutions, the agency that would administer such a programme, still describes paid family and medical leave only as a task force that reported recommendations to the Governor and the Legislature in October 2022. Any text saying an employer shall allow twelve weeks of leave beginning 1 January 2026 is bill language from a bill that died, not statute. What New Mexico does require is unpaid-to-you but real: the Healthy Workplaces Act took effect on 1 July 2022 and applies to every private employer with no minimum size. Each employee accrues one hour of earned sick leave for every 30 hours worked, may use up to 64 hours in a twelve month period, and carries over up to 64 accrued hours unless you front load the full amount at the start of the year. An existing paid time off policy satisfies the Act if the leave can be used for the same purposes on the same terms. This is a cost you carry on your own payroll, not a premium you remit to the state.

Do you need a sales tax permit in New Mexico?

New Mexico has no general sales tax, so there is no sales tax permit to apply for. That does not always mean nothing to register for, as the note explains.

There is no New Mexico sales tax permit to apply for, because New Mexico has no sales tax. What you register for instead is a New Mexico Business Tax Identification Number, which is the account for the gross receipts tax described below, and the Department states plainly that there is no fee to register or obtain one. You apply through Taxpayer Access Point and the number is generally issued within one business day, or you can file Form ACD-31015 by email or at a district office. One number covers gross receipts tax, compensating tax and wage withholding. Two obligations start the moment you hold it: you file a return for every period even when you had no receipts at all, and a late return carries a $5 civil penalty even when no tax is due. The number does not lapse when you stop trading, so close it on Form ACD-31015 rather than simply stopping.

Does a marketplace like Amazon or Etsy handle the tax for you?

New Mexico does have a marketplace law; it just runs through the gross receipts tax rather than a sales tax. A marketplace provider that facilitated at least $100,000 of taxable gross receipts sourced to New Mexico in the previous calendar year must register and pay gross receipts tax on everything it facilitates, including the money it later passes on to you, plus its own fees. As a marketplace seller you still have gross receipts on the same sale, but Section 7-9-117 NMSA 1978 lets you deduct the receipts the provider paid the tax on, so you report them and then deduct them rather than ignoring them. The catch is that the deduction depends on the provider actually paying: if it does not, and you are engaging in business in New Mexico, the sale is still taxable and the tax falls back on you. Keep the platform's evidence of payment.

If your sales drop, when can you stop collecting?

New Mexico never uses the phrase trailing nexus, but the effect is the same and it runs a full calendar year. Whether a remote seller is engaging in business is decided entirely on the prior year: the Department states that the $100,000 determination is based on the previous calendar year regardless of the taxable gross receipts in the current calendar year. So a year in which you cross $100,000 commits you to registering, collecting and filing for the whole of the next calendar year even if your New Mexico sales collapse to nothing in it, and you only drop out in the year after that. Separately, the account outlives the liability: the New Mexico Business Tax Identification Number stays open and you keep filing zero returns until you close it with the Department on Form ACD-31015.

Does New Mexico charge a tax on revenue rather than profit?

This is the single most important thing to understand about New Mexico. The state has no sales tax as such. It levies a gross receipts tax on the seller for the privilege of doing business here, and the Department's own wording is that the tax is imposed on businesses but it is common for a business to pass it on to the purchaser, in which case it has to be stated separately on the invoice. In a shop it looks and behaves like a sales tax, which is why almost every rate table lists New Mexico alongside sales tax states. The legal difference is not cosmetic and shows up in three places. Liability sits with you rather than with the buyer, so anything you failed to add to a customer's bill is still your debt to the state. The base is much broader than a typical sales tax because services are taxable as well as goods, including most professional services billed to a New Mexico client. And there are no deductions for business expenses, so this is charged on revenue and not on margin, with no cost of goods or payroll subtracted. Rates are set by location and sourcing has been destination based since 1 July 2021, so you use the rate for where the goods or the product of your service are delivered; an out-of-state business with no New Mexico location reports under code 88-888 at the 4.875% state rate. Since 1 July 2025 rates change only in July, once a year, unless a natural disaster forces a January change, and the Department publishes one rate schedule a year in the GRT Filer's Kit. There is no small-business exclusion: unlike Delaware or Nevada, once you are engaging in business the first dollar of taxable receipts is taxed. Note that the Department's own overview publication FYI-105, dated 11 August 2025, still gives the range as 4.875% to 10.8125%; the range here is read off the current rate schedule itself, where the highest combined rate is 9.4375% at Taos Ski Valley and the lowest ordinary county remainder is 5.25%. Where an explainer and the current schedule disagree, the schedule governs. Compensating tax, the use-tax counterpart, applies at the same state rate to things you buy without paying gross receipts tax.

Do you have to register your out-of-state company in New Mexico?

Foreign LLC: $100 to issue the registration, fixed by Section 53-19-63(K) NMSA 1978. Foreign corporation: no single figure, because Section 53-2-1(A)(13) charges $1.00 for each 1,000 authorized shares represented in New Mexico with a floor of $200 and a ceiling of $1,000, so a small corporation pays exactly $200 and only one representing more than 200,000 shares in the state pays more.

All New Mexico business filings are now online only: the Secretary of State no longer accepts paper applications, so you file through enterprise.sos.nm.gov. Two things follow. A foreign corporation owes an initial corporate report within 30 days of its certificate of authority being issued and then a report every two years, due the fifteenth day of the fourth month after its taxable year ends, at $25 each under Section 53-2-1(A)(16); the Limited Liability Company Act sets no matching periodic report for a foreign LLC. And qualifying with the Secretary of State does not register you for tax: the Business Tax Identification Number from the Taxation and Revenue Department is a separate step, and so is the unemployment insurance account at Workforce Solutions. Skipping qualification bites in court first. Neither a foreign corporation nor a foreign LLC may bring or maintain an action in a New Mexico court until it registers, though either can still defend one and its contracts stay valid. On top of that a foreign corporation owes every fee it should have paid plus a $200 civil penalty per offence, and an unregistered foreign LLC faces up to $200 for each year or part year plus an injunction against doing further business until it pays. Section 53-17-1 NMSA 1978 lists activities that do not by themselves amount to transacting business, including holding bank accounts, selling through independent contractors, soliciting orders that are only binding once accepted outside the state, and a single isolated transaction completed within 30 days.

Where these figures come from

Every number on this page was read on New Mexico's own agency pages, its statute, or a current-year official form, and this record was last reviewed on 2026-09-08. Where a state's explainer page disagreed with its statute or its current form, we followed the statute or the form and said so in the relevant section, because a state's consumer-facing pages are often the last thing updated when a figure changes.

Anything we could not confirm on a primary source is left blank rather than estimated. A missing figure on this page means we could not verify it, not that it is zero.

This is general information, not legal or tax advice. Rules change and your circumstances matter. Confirm anything you are about to act on with the agency named beside it.
