Customize this checklistPopular New Mexico business types:
Do this first. The state tax and payroll accounts ask for your registration details.
Apply free on the IRS website and get the number immediately. You'll need it for the state tax registration, a business bank account, and payroll. Opening a new location? You already have one; the same EIN works in every state.
This internal document sets out who owns what, how decisions get made, and what happens if an owner leaves. It isn't filed with the state, but banks often ask for it, and it helps protect your liability shield. Single-owner LLCs need one too.
Bring your EIN letter, filed formation documents, and operating agreement or bylaws. Keeping business and personal money separate is one of the main things that protects your personal assets.
Many businesses need a license or permit before opening, separate from registering the company. Check three levels: the state licensing board for your field, your city or county, and any federal agency that regulates your industry.
If you want S corp taxation, file IRS Form 2553. The deadline is tight: generally within 2 months and 15 days after the start of the tax year you want it to apply. See Business basics for when it makes sense.
File Articles of Organization (or the state's equivalent) online through Secretary of State Business Portal (enterprise.sos.nm.gov).
The registered agent needs a New Mexico physical address. P.O. boxes are not allowed.
New Mexico has no state DBA registry. Some counties may require you to file a trade name with the county clerk.
Out-of-state entities applying for authority must include a good standing certificate from their home state dated within 30 days. Online filings add a $1.95 convenience fee.
Register for a free New Mexico Business Tax ID (NMBTIN) online through the Taxpayer Access Point (TAP), usually issued in 1 business day. One ID covers gross receipts tax, compensating tax and wage withholding.
Gross receipts tax rates vary by city and county, so charge the rate for where the service is delivered. Some cities require their own business license.
New Mexico taxes the seller's gross receipts, including most services, not just goods. File your gross receipts and withholding returns on time even when no tax is due, or you face a $5 penalty.
Applies if you sell products, or services this state taxes. Most medical care is exempt. See Business basics for sales tax.
New Mexico calls it a Business Tax Identification Number (BTIN) registration for Gross Receipts Tax. Register with the New Mexico Taxation and Revenue Department through Taxpayer Access Point (TAP), or Form ACD-31015, Application for Business Tax Identification Number before you make your first taxable sale in New Mexico. You'll collect tax from customers and send it to the state.
Give your supplier Nontaxable Transaction Certificate (NTTC) so you don't pay tax on inventory you'll resell. Buyers get NTTCs from the department and give them to sellers; sellers may accept the MTC certificate only from certain out-of-state buyers not required to register in New Mexico, and New Mexico does not issue MTC certificates. Keep certificates your own customers give you, too.
Out-of-state sellers must register once sales into New Mexico pass $100,000 (previous calendar year), even with no office here.
Since July 1, 2025, local rates change only once a year in July, except in special cases like natural disasters.
Applies once you pay W-2 employees who work in this state.
Form I-9 is never mailed to the government. You keep it in your own files and show it only if ICE or the Department of Labor asks for an inspection.
Federal posters (minimum wage, EEO, FMLA if you have 50+ employees, and others) go alongside the state ones.
Register once you pay wages to employees working in New Mexico. Reports and payments are usually quarterly.
Required at 3 or more employees (1 or more for construction businesses licensed by CID). Employers with fewer than 3 employees can buy coverage voluntarily. A $4.30 quarterly assessment per worker is paid on top of the premium.
Report full-time, part-time and temporary hires and rehires through the NM New Hire website or the New Mexico Employer Online Portal.
New Mexico's wage payment rules:
$12.00 an hour.
The Healthy Workplaces Act covers every private employer, regardless of size. Employees earn 1 hour per 30 hours worked from day one and can use up to 64 hours a year.
This is a voluntary state retirement program, not a mandate. It was set to launch July 1, 2024, but was put on indefinite hold because the legislature did not fund it.
New Mexico doesn't require harassment training for private employers. A written policy and a yearly refresher are still best practice.
Display the state's required labor law posters where employees can see them, along with the federal posters. Workers' comp notices come from your carrier.
Employers pay $4.30 per employee each quarter to Taxation and Revenue on Form WC-1, separate from insurance premiums. Up to $2.00 can be deducted from the worker's pay.
These local laws apply to employees who work within the city or county, on top of the state rules. Where they differ, follow whichever is more generous to the employee.
The W-9 gives you the contractor's legal name and tax ID for their 1099. Check the classification first: if you control how and when they work, they may legally be an employee.
File with the IRS and send the contractor a copy by January 31. For payments made in 2026 and later, the reporting threshold is $2,000 per contractor per year (it was $600 before).
Recurring deadlines. Put these on your calendar now.
FinCEN's final rule, effective August 14, 2026, permanently exempts companies formed in the U.S. from beneficial ownership reporting. Ignore letters or emails demanding a BOI filing fee; they're a common scam. Only companies formed outside the U.S. still file.
Malpractice damage caps and the $250,000 personal liability limit apply only to qualified providers. You qualify by carrying the required coverage and paying the fund surcharge through your insurer.
Keeps your business in good standing with the state. Missing it can lead to penalties or dissolution.
Corporations may owe a $50 corporate franchise tax even if they owe no corporate income tax. A late corporate report costs $200.
File unemployment wage reports each quarter and state withholding returns on the schedule you're assigned (if the state has income tax), plus the annual W-2 reconciliation.
Monthly if tax averages more than $200 a month, quarterly if under $600 a quarter, or semiannually if under $1,200 per six months; returns are due the 25th of the month after the period. File a zero return if you had no sales; skipping it can bring penalties.
Recurring dates for New Mexico and federal filings. A payroll service handles most payroll lines, but you should know they're happening.
