New Mexico payroll setup for your first hire

New Mexico takes state income tax from paychecks. Those amounts sit with TRD, not the unemployment office.

New Mexico takes state income tax from paychecks. This is not Texas, Florida, Washington, Tennessee, or Nevada. Those states do not take state income tax from paychecks. A federal Employee’s Withholding Certificate (Form W-4) is the New Mexico certificate too. New Mexico does not print a separate state form. The personal-income FAQ says complete a federal W-4 and write “For New Mexico Withholding Tax Only” across the top. Keep that copy. Do not send it to TRD.

Get a federal Employer Identification Number, called EIN, from the IRS first. The who-must-register page then sends you to TAP. From the TAP home page, choose Apply for a New Mexico Business Tax ID. You may also mail Form ACD-31015, the Business Tax Registration. There is no fee to open that file. After the file exists, TRD assigns a New Mexico Business Tax Identification Number, called NMBTIN. Software pages also call that number a CRS ID, formerly the Combined Reporting System ID. A federal EIN is not that number. A Department of Workforce Solutions unemployment number is not that number either. Use the same employer name and EIN you will print on Form W-2. Hold the NMBTIN. A mailed Form ACD-31015 is processed in the order received. Confirm the live letter.

After the account exists, file later withholding on Form TRD-41414, the Wage Withholding Tax Return. File that return on TAP. The withholding page says an employer who withholds federal income tax must withhold New Mexico income tax. Use FYI-104 for the withholding tables. Combined taxes on Form ACD-31015 set the later cycle. Monthly shops average more than $200 a month. Quarterly shops stay under $600 in a quarter. Semiannual shops stay under $1,200 in six months. Confirm the live cycle on TAP. New Mexico does not use federal Form 941 as the state withholding return. Do not copy Nebraska’s Form 941N onto New Mexico. Do not copy Idaho’s Form 910 onto New Mexico. Do not copy Iowa’s Form 44-095 onto New Mexico. This TAP is not Idaho’s TAP. It is not Utah’s TAP. It is not Mississippi’s TAP.

When you owe unemployment: $450 in a quarter, or one person in 20 weeks. Register on the UI Tax Self-Service System when that test is met.

DWS collects state unemployment tax. That tax is often called SUTA, state unemployment tax, or SUI, state unemployment insurance. NMSA 1978 § 51-1-42, the employer handbook, and 11.3.400.409 NMAC restate the regular-shop test. You become a liable employer if you pay $450 or more in a calendar quarter, or if you employ at least one person for some portion of a day in each of 20 different calendar weeks, whether or not consecutive. This is not California’s $100-in-a-quarter test. There is no 15-day California clock on the DWS page. Do not copy that clock onto New Mexico. This is not Nebraska’s, Wisconsin’s, or Idaho’s $1,500-quarter pair. This is not Iowa’s any-wages test. This is not Nevada’s $225-quarter test. This is not Indiana’s $1 covered-wage test. This is not Oregon’s $1,000-quarter or 18-week test. This is not Utah’s one-person, some-portion-of-a-day clock. New Mexico does take state paycheck withholding. Do not treat New Mexico like a no-withholding state.

The same rule names other paths. Domestic work in a private home uses $1,000 cash wages in a quarter. Agricultural labor uses $20,000 cash wages in a quarter, or ten people in 20 weeks. This scorecard is the regular-business path.

11.3.400.409 NMAC is the file clock. Register the business online when you have hired the first employee and you meet the $450-quarter or 20-week test. That is not Nebraska’s file-UI-Form-1-even-if-not-liable clock. It is not Idaho’s six-month IBR clock after you become covered. It is not Iowa’s 30-day myIowaUI clock after the first paycheck. It is not Kansas’s 15-day Form K-CNS 010 clock. It is not Louisiana’s 30-day apply-even-if-not-liable clock after the first wages. Do not wait for a $1,500-quarter test that New Mexico does not use. Do not copy Gusto’s $500-quarter line onto the official test. The official line is $450.

File that registration on the Unemployment Insurance Tax Self-Service System. The UI Tax page is the same door. After the account exists, DWS assigns an Employer Account Number, called EAN. Hold the number. You also receive a user ID and password. Activate that login before DWS will take wage records or payments. Do not substitute a federal EIN for that number. Do not substitute the NMBTIN from TRD.

The quarterly unemployment file sits with DWS. The quarterly TRD-41431 file sits with TRD. They are not the same job.

Those are two jobs. The UI Tax Self-Service System is where you file later wage reports and pay unemployment tax. 11.3.400.404 NMAC says file that quarterly wage and contribution report by the last day of the month after the quarter, even when no wages were paid, until DWS closes the file. 11.3.400.407 NMAC says a new employer’s first contribution is due the last day of the month after the quarter in which the shop became liable. That first payment covers contributions that accrued during that calendar year. A quarterly DWS wage report is not the new-hire report. A quarterly DWS wage report is not Form TRD-41414.

The how-rates-are-calculated page says a new contributing employer uses the greater of the industry-average rate or 1%. That printed 1% floor stays until you have two years as an experience-rate shop. Use the rate on your DWS notice, not a number from a software page. The UI Tax page prints the 2026 taxable wage base as $34,800. Wages above that base must still be reported. They are not taxed. Nebraska’s 2026 wage base is $9,000. Idaho’s 2026 wage base is $58,300. Do not copy those wage bases onto New Mexico.

TRD also collects a workers’ compensation assessment fee. That fee is not unemployment tax. For periods that begin on or after January 1, 2026, file Form TRD-41431, the Workers’ Compensation Fee Return and Employees’ Quarterly Wage and Withholding Report, on TAP. The TAP FAQ says TRD-41431 replaces Form TRD-41054, also called WC-1, and Form TRD-31109 for those later periods. File TRD-41431 by the 25th day of the month after the quarter. You still file Form TRD-41414 for wage withholding. Those two TAP files do not open the DWS unemployment account.

New hire is a 20-day Directory report. A quarterly DWS wage report does not take it.

The new-hire report is a list of who you just hired. It is not a box on the quarterly DWS wage report. In New Mexico that report goes to the New Mexico New Hire Directory. File on nm-newhire.com. The Health Care Authority employer page, the directory law page, and the directory FAQs require a report of a new employee within 20 days of the date of hire. Report a rehire if the last job with you ended at least 60 days before the first day back. Report temporary workers. The start date is the first day the person worked for wages. You also send the employer’s federal EIN. The same FAQs welcome independent-contractor reports. They are not required.

NMSA 1978 § 50-13-1 through § 50-13-4 print the State Directory of New Hires. A quarterly DWS wage report does not satisfy that clock. A quarterly Form TRD-41431 does not satisfy that clock either. This is not Iowa’s 15-day Centralized Employee Registry report. This is not Alabama’s seven-day report. This is not Georgia’s 10-day report. This is not Massachusetts’s 14-day Department of Revenue report. Most peer states use a 20-day clock. New Mexico’s 20-day clock sits with the New Hire Directory and the Health Care Authority, not with the DWS unemployment portal. That is Nebraska’s split. It is not Idaho’s path. Idaho sends the new-hire file to the same Department of Labor that collects unemployment tax.

Workplace injury insurance is due when you have three employees. Construction shops do not wait. The assessment fee is not the policy.

This is Georgia’s, North Carolina’s, Virginia’s, and Arkansas’s three-employee path for a regular shop. It is not Nebraska’s, Kentucky’s, Connecticut’s, Louisiana’s, Oklahoma’s, Nevada’s, Utah’s, Iowa’s, or Idaho’s first-employee path. It is not Texas optional coverage. It is not Mississippi’s, Alabama’s, or Tennessee’s five-employee wait. It is not Florida’s or South Carolina’s four-employee wait. It is not Wisconsin’s three-employee or $500-quarter path. It is not Kansas’s $20,000 payroll line. It is not Washington’s exclusive state fund. It is not Ohio’s Bureau of Workers’ Compensation monopoly. New Mexico calls this workers’ compensation.

The Workers’ Compensation Administration is the workplace-injury office. NMSA 1978 § 52-1-6, the WCA FAQs, and the employer guidebook say a regular shop must keep a policy when it has three or more workers. Count owners who work in the shop, family members, and part-time, temporary, and seasonal workers. The same statute covers every shop that must hold a Construction Industries Licensing Act license, even with fewer than three people. Domestic work and farm or ranch labor sit outside the regular-shop line unless the shop elects in. This scorecard is the regular-business path.

The WCA does not sell that policy. The guidebook says buy a licensed commercial policy, qualify to self-insure or join a group self-insurance plan, or use the assigned-risk pool if a voluntary policy is not available. New Mexico is not a monopolistic state fund. That is not Washington’s exclusive L&I fund. It is not Ohio’s Bureau of Workers’ Compensation monopoly. A payroll login is not a policy.

The assessment fee is a separate TRD bill. NMSA 1978 § 52-5-19 and the withholding page say every covered employer and every covered worker pays that fee. Count covered workers on the last working day of the quarter. Beginning July 1, 2025, the employer share is $2.55 and the worker share is $2.25. The same page says paying the fee does not mean you have workplace injury insurance. File that fee on Form TRD-41431. Do not treat WC-1 as the live 2026 form.

How Gusto and Patriot describe New Mexico

Confirm the live NMBTIN on TAP. Confirm the Employer Account Number and rate on the UI Tax Self-Service System. Confirm workplace injury insurance with a licensed carrier. Confirm the 20-day new-hire file with the New Mexico New Hire Directory.

Gusto’s New Mexico help article says Middesk (Gusto’s business-verification company) may register state income-tax withholding and state unemployment insurance (SUI). It names the Taxation and Revenue Department for withholding and the Department of Workforce Solutions for unemployment tax. It sends shops to TAP to apply for a New Mexico Business Tax ID. That TAP path matches the who-must-register page. It says an online withholding account can arrive the same day. Confirm the live TAP letter. The same article says a DWS unemployment account can take about ten business days. Confirm the live DWS letter. It lists Form TRD-41414, Form RPD-41072, Form ES-903A, and WC-1 among New Mexico files. Form TRD-41414 matches the withholding page. WC-1 is the name on the software page for periods that begin on or after January 1, 2026. TRD now names Form TRD-41431 for that quarterly fee and wage file. The article also prints the unemployment test as $500 in a quarter or one person in 20 weeks. That $500 line is what the software page says. § 51-1-42 and the handbook print $450. Middesk’s standard order does not open workplace injury insurance. Read Gusto’s New Mexico article. See Gusto on the directory.

Patriot’s registration article tells new shops to open withholding on TAP and to sign up for a workers’ compensation account on the same application. That TAP line matches the TRD door. The article still tells shops to file WC-1. WC-1 is the name on the software page for 2026 periods. The official 2026 file is Form TRD-41431. The same article sends unemployment to the Department of Workforce Solutions for an Employer Account Number. That DWS door matches the UI Tax page. It prints the new-employer unemployment rate as the greater of the industry average or 1%. That printed floor matches the how-rates-are-calculated page. Use the rate on your live DWS notice, not a number from a software page. The article tells employees to complete Form W-4 for federal and New Mexico tax. The official FAQ still asks for a second W-4 marked “For New Mexico Withholding Tax Only.” It also says workplace injury insurance is due if you have at least three employees, through a private provider or a state-operated fund. The three-employee line matches § 52-1-6. The state-fund line is what the software page says. The ordinary New Mexico path is a licensed commercial policy, the assigned-risk pool, or approved self-insurance. It is not a Washington-style exclusive state fund. Read Patriot’s registration article. See Patriot on the directory.

What still sits on the employer

• Decide that you have paid $450 in a quarter, or employed one person in 20 weeks. Domestic and agricultural paths use other tests. Register on the UI Tax Self-Service System when you have hired the first employee and you meet that test.
• Complete that registration on the Unemployment Insurance Tax Self-Service System. 11.3.400.409 NMAC starts that file when the first employee is hired and the $450-quarter or 20-week test is met.
• Hold the NMBTIN from the Taxation and Revenue Department. Hold the Department of Workforce Solutions Employer Account Number. Do not substitute a federal EIN for either number.
• Enter the unemployment rate from the DWS notice, not a marketing figure. A new contributing shop uses the greater of the industry-average rate or 1%. The 2026 wage base is $34,800. Confirm the live notice.
• File the quarterly DWS wage report on the UI Tax Self-Service System after the account exists, even in a zero-wage quarter until DWS closes the file. 11.3.400.404 NMAC puts that file on the last day of the month after the quarter. 11.3.400.407 NMAC puts a new shop’s first contribution on the last day of the month after the liability quarter. That report is not withholding. It is not Form TRD-41431.
• Register withholding on TAP or Form ACD-31015 before the first withheld paycheck. Collect a federal W-4 marked “For New Mexico Withholding Tax Only.” File Form TRD-41414 on the cycle TAP assigns. File Form TRD-41431 each quarter for the assessment fee and the employee wage listing.
• File the 20-day new-hire report with the New Mexico New Hire Directory. A quarterly DWS wage report does not satisfy that clock. A quarterly Form TRD-41431 does not satisfy that clock either.
• Buy workplace injury insurance when you have three employees in a regular shop. Construction shops licensed under the Construction Industries Licensing Act do not wait for three. The WCA does not sell that policy. The assessment fee is not the policy. Payroll software does not issue that policy.
• Do not copy another state’s clock onto New Mexico. New Mexico does not use California’s $100-quarter test. New Mexico does not use Nebraska’s $1,500-quarter test. New Mexico does not use Nebraska’s file-even-if-not-liable UI Form 1 clock. New Mexico does not use Idaho’s six-month IBR clock. New Mexico does not use Iowa’s any-wages unemployment test. New Mexico does not use Iowa’s 30-day myIowaUI clock. New Mexico does not use Kansas’s 15-day Form K-CNS 010 clock. New Mexico does not use Louisiana’s 30-day apply-after-first-wages clock. New Mexico does not use Nevada’s $225-quarter test. New Mexico does not use Indiana’s $1 unemployment test. New Mexico does not use Oregon’s $1,000-quarter or 18-week test. New Mexico does not use Utah’s one-person, some-portion-of-a-day unemployment clock. New Mexico does not use Arkansas’s ten-day unemployment test. New Mexico does not skip state paycheck withholding the way Texas, Florida, Washington, Tennessee, or Nevada do. New Mexico does not open withholding the way Idaho does. New Mexico’s TAP is not Idaho’s TAP. New Mexico does not use Iowa’s 15-day new-hire clock. New Mexico does not use Alabama’s seven-day new-hire clock. New Mexico does not use Georgia’s 10-day new-hire clock. New Mexico does not send the new-hire file to the unemployment office the way Idaho does. New Mexico does not use Nebraska’s first-employee workplace-injury path. New Mexico does not use Mississippi’s, Alabama’s, or Tennessee’s five-employee workplace-injury wait. New Mexico does not use Florida’s or South Carolina’s four-employee wait. New Mexico does not use Kansas’s $20,000 payroll workplace-injury line. New Mexico does not use Wisconsin’s three-employee or $500-quarter path as the only test. New Mexico does not use Texas optional coverage. New Mexico does not use Washington’s exclusive state fund. New Mexico does not use Ohio’s Bureau of Workers’ Compensation monopoly. New Mexico does not use Idaho’s State Insurance Fund door.
