New Mexico employers must file Form ES-903A every quarter to report employee wages and calculate unemployment insurance contributions. It is a routine requirement, but missing it can lead to penalties, interest, and avoidable compliance problems.
If you handle payroll, this report is one of the most important recurring documents in the state. Understanding what goes on Form ES-903A, when it is due, and how to submit it can save time and help keep your business in good standing.
New Mexico Quarterly Wage Report Form ES-903A Basics
The New Mexico Employer’s Quarterly Wage and Contribution Report, Form ES-903A, is a mandatory filing with the New Mexico Department of Workforce Solutions. It reports wages paid to employees and the unemployment insurance tax owed by the employer.
This form helps the state track payroll activity and fund unemployment benefits. Even if your business had no wages to report during a quarter, you still generally need to submit the form and indicate that no wages were paid.
New Mexico Quarterly Wage Report Form ES-903A Due Dates
Form ES-903A is due by the last day of the month after each calendar quarter ends. That means the filing schedule follows a predictable quarterly pattern throughout the year.
Here are the standard due dates:
- First Quarter, January 1 through March 31: April 30
- Second Quarter, April 1 through June 30: July 31
- Third Quarter, July 1 through September 30: October 31
- Fourth Quarter, October 1 through December 31: January 31
If a due date falls on a weekend or legal holiday, the report is due on the next business day. That detail matters because a payment or filing submitted late can trigger penalties even if the delay was only by a day.

New Mexico Quarterly Wage Report Form ES-903A Filing Requirements
Employers should treat Form ES-903A as a required compliance filing, not just a payroll routine. The report needs to reflect accurate wage information, taxable wages, and any related tax amounts.
Even when payroll was inactive for the quarter, filing is still required. In that case, employers should submit the report with “NONE” entered in the wage sections rather than leaving it out.
Who Must File Form ES-903A
Most employers covered by New Mexico unemployment insurance rules must file this quarterly report. If you pay wages to employees in New Mexico, you should assume reporting obligations apply unless you have confirmed otherwise with the state.
New employers and businesses with fluctuating payrolls should be especially careful. A quarter with no payroll does not eliminate the filing duty.
How to Handle a No-Wage Quarter
If no wages were paid during a quarter, the report should still be filed. The state expects a return showing no wages rather than silence.
That simple step can help prevent notices, late filings, or errors in the employer account record. It is one of the easiest compliance issues to overlook.
New Mexico Quarterly Wage Report Form ES-903A Schedule A
Schedule A is the summary section of the form. It gives the state a broad view of the wages paid and the taxes due for the quarter.
This section typically includes totals such as gross wages, excess wages, taxable wages, total tax due, interest due, and any late penalties. Because it is the summary, figures here should match the detail reported elsewhere on the form.
Key Schedule A Fields
The numbers in Schedule A should be reviewed carefully before filing. Small payroll mistakes can create larger filing issues if totals do not line up.
Common items include:
- Total wages paid during the quarter
- Deductions for excess wages
- Taxable wages
- Total tax due
- Interest, if applicable
- Late report and payment penalties, if applicable
New Mexico Quarterly Wage Report Form ES-903A Schedule B
Schedule B contains the employee-by-employee wage details. This section supports the summary totals shown in Schedule A and gives the state a more complete record of payroll activity.
Each employee listed should have the correct identifying and wage information. Accuracy is especially important because errors here can affect wage records and unemployment reporting.
Employee Details Required in Schedule B
Employers must typically provide each employee’s Social Security number, name, gross wages for the quarter, and excess wages if any apply. Depending on the reporting format, additional payroll-related fields may also be required.
Review each worker entry before submission to make sure names and wage amounts match payroll records. A clean Schedule B reduces the chance of later corrections.
New Mexico Quarterly Wage Report Form ES-903A Penalties and Interest
Late filing can become expensive quickly. New Mexico imposes specific penalties and interest charges when employers do not file or pay on time.
The late report penalty is a fixed $50.00. If the payment is late too, the late payment penalty is an additional 5% of the tax due or $25.00, whichever is greater.
Interest accrues at 1% per month on unpaid tax amounts after the due date. That means a short delay can continue generating costs until the balance is paid.

New Mexico Quarterly Wage Report Form ES-903A Submission Methods
Employers can file Form ES-903A online or by mail. Electronic filing is generally encouraged because it is faster and can reduce handling errors.
For certain employers, online filing is mandatory. Businesses with 25 or more employees must file electronically under New Mexico rules.
Online Filing for Form ES-903A
Online filing is typically the most efficient option for timely submission. It can also help employers keep better records of what was filed and when.
If your business has multiple payroll runs or a complex wage structure, online filing can make quarterly reporting easier to organize and confirm.
Mail Filing for Form ES-903A
Employers who may file by mail should send the completed form to the New Mexico Department of Workforce Solutions, P.O. Box 2281, Albuquerque, NM 87103.
Mail filings should be sent early enough to account for delivery time. Waiting until the due date can create risk if the form arrives late.
New Mexico Quarterly Wage Report Form ES-903A Corrections and Multiple Worksites
Payroll reporting does not always go perfectly the first time. If an employer finds an error after submitting the form, a correction may be required.
Businesses with more than one worksite may also have extra reporting obligations. These situations usually call for additional attention to detail so that state records match actual payroll activity.
How To Correct Form ES-903A
If a mistake is discovered in a previously filed report, employers must file Form ES-903C to correct the information. This helps the state update wage and tax records properly.
Correcting errors promptly can prevent bigger problems later, especially if wages affect employee records or tax balances.
Multiple Worksite Reporting in New Mexico
Employers with multiple locations may need to submit the Multiple Worksite Report, also known as BLS 3020. This report provides more detailed employment and wage information for each site.
It is especially useful for businesses with decentralized operations, since the state may need location-specific data to maintain accurate reporting.
New Mexico Quarterly Wage Report Form ES-903A Best Practices
Good filing habits can prevent most Form ES-903A problems before they start. The best approach is to reconcile payroll records before each filing deadline and keep supporting documents organized.
It also helps to create a quarterly checklist for wage totals, employee counts, taxable wages, and payment confirmation. That way, nothing important is missed when the deadline approaches.
When in doubt, review instructions before filing instead of guessing. A few extra minutes of review can save time, money, and follow-up notices later.
