QuickBooks Prefills New Mexico Form WC-1 — Here's What You Still Need to Check
QuickBooks auto-fills most of the New Mexico Workers' Compensation Fee Form, but employers must verify key fields and know the zero-report rule.
New Mexico employers filing Form WC-1 — the Workers’ Compensation Fee Form — through QuickBooks get most of the heavy lifting done automatically, but several fields still require a manual review before the return is ready to submit.
QuickBooks populates the form using the company, payroll, and employee data already on file. In the typical case where that information is complete and current, there is little left to enter by hand. The catch is knowing which fields those are and what the numbers mean, because a quick visual check is the only reliable way to catch a missing identifier or an employee-count error before the form goes out.
Who Has to File
The filing requirement is broad. Any employer required to carry workers’ compensation coverage for New Mexico employees must file Form WC-1 and pay the associated fee. That sweep covers most businesses with employees in the state, regardless of whether they operate for profit — non-profits and churches are included.
A much narrower group must also file: employers who are technically exempt from the coverage mandate but have chosen to carry workers’ compensation insurance anyway. This applies only to non-construction businesses with fewer than three employees who opted in voluntarily.
If your business temporarily has no covered employees during a quarter, you are still on the hook to file — just not to pay. In that situation, file a zero report indicating no covered workers and remit no money.
The Fields QuickBooks Fills Automatically
QuickBooks draws on existing payroll records to prefill the bulk of the form. The line items that generally populate without intervention include the worker count on Line 1 and the assessment calculation on Line 2. If you have no covered employees for the quarter, QuickBooks enters zero on Line 1.
The Fields You Need to Verify
Several fields either will not auto-populate or warrant a closer look regardless:
New Mexico Business Tax ID Number (BTIN) — This is the identifier assigned by the Taxation and Revenue Department, sometimes referred to simply as the New Mexico tax ID. Confirm it is present and correct.
EAN ID Number — The Employer Account Number is issued by the New Mexico Department of Labor and is used for quarterly Unemployment Insurance reporting. It is sometimes called the UI number. QuickBooks notes that this field is not required for filing the WC-1, so a blank here will not block submission.
Line 1 — Number of Covered Workers — This is the count of covered employees on the last working day of the calendar quarter being reported. Even though QuickBooks calculates it, it is worth verifying against your actual headcount for that specific date.
Line 2 — Assessment Fee — The fee is calculated at a fixed rate per employee per calendar quarter, based on the Line 1 count. The per-employee amount is split between the employee and the employer. Each covered worker should generate either the full assessment or zero — nothing in between.
Line 3 — Penalty — If you have received a notice assessing a penalty, enter that amount here. QuickBooks has no way to know about an incoming penalty notice, so this line is entirely manual.
Line 4 — Interest — The same logic applies to assessed interest. If you have been notified of an interest charge, enter the amount on Line 4.
When Prefill Comes Up Short
The most common stumbling block is incomplete underlying data. If employee records or company information in QuickBooks are outdated or missing entries, the form’s prefilled values will reflect those gaps. Reviewing the form line by line before filing is the practical safeguard.
For broader help with the form window itself or for troubleshooting a specific issue with how the form is behaving, the built-in Help button on the form screen points to QuickBooks’ own guidance on navigating the interface and resolving common problems. If you are dealing with payroll form errors or data issues more generally, the same help resources cover many of the recurring filing-window problems users encounter.
The bottom line for New Mexico employers: QuickBooks handles the arithmetic and most of the data entry for Form WC-1, but the BTIN, the employee count on the last working day of the quarter, and any penalty or interest amounts from recent notices all call for a manual check before you file.
