Bonus inputs

Use gross-to-net for a planned bonus or net-to-gross when a take-home amount was promised. This estimates one taxable cash bonus for a W-2 employee; use a full paycheck calculation for regular or periodic wages.

Gross bonus amount Enter the taxable bonus to be paid.

Federal withholding method

Payment presentation Federal flat withholding can apply only to a separately identified amount when eligible. Automatic New Mexico treatment pairs 5.9% with the federal flat method, Table 8 with a separately paid aggregate bonus, and a period-table difference with combined pay.

Regular wages had federal income tax withheld

The optional 22% federal method generally requires federal income tax to have been withheld from regular wages in the current or immediately preceding year.

Regular pay frequency Used by federal aggregate withholding and the New Mexico period-table difference. New Mexico Table 8 always uses its daily or miscellaneous schedule.

YTD Social Security wages from this employer Used only for the 2026 $184,500 Social Security wage-base check.

YTD Medicare wages from this employer Used for the employer's $200,000 Additional Medicare withholding threshold.

YTD supplemental wages before bonus Include 2026 supplemental wages paid by this employer and businesses under common control for the federal $1 million test.

Regular wages for the federal reference pay period Used only by the federal aggregate calculation.

Extra federal withholding per regular check

Extra federal withholding in aggregate mode Added only to the aggregate result; it never changes the prescribed 22% or 37% rates.

Actual federal withholding on reference wages Aggregate mode subtracts this actual amount when provided. If the federal eligibility box is clear and this is blank, the baseline defaults to $0.

New Mexico withholding settings

New Mexico withholding profile Profiles are planning presets. Confirm residency, work location, the 15-day rule, tribal-land facts, military rules, and the employee's New Mexico W-4 copy before payroll.

New Mexico income-tax withholding applies

Profile presets update this control. New Mexico uses a copy of the federal W-4 marked “For New Mexico State Withholding Only”; it has no separate state W-4 form.

New Mexico bonus withholding method FYI-104 says to use the same type of method used federally, sets 5.9% when federal withholding uses a flat percent, and recommends Table 8 for bonuses paid separately from normal wages.

New Mexico filing status A married employee electing the higher single rate for federal purposes must use Single for New Mexico withholding.

New Mexico-taxable bonus percentage Use a supportable New Mexico-source allocation for a nonresident. New Mexico residents are generally subject to withholding on all wages.

Regular New Mexico-taxable wages for this pay period Used only by the period-table combined-minus-regular method.

Actual New Mexico withholding on regular wages When entered, the aggregate calculation subtracts this actual paystub amount instead of the modeled regular-wage table amount.

Other New Mexico withholding due this calendar month FYI-104 says no withholding is required when an employee's total New Mexico withholding for a month is less than $1. Enter other current-month withholding so that rule is not applied to the bonus in isolation.

Additional New Mexico withholding on this bonus Optional one-time amount added once after the selected state method and included in the monthly $1 test.

Custom New Mexico withholding rate Used only for a documented custom percentage; it does not replace the official 5.9% flat rule.

Current table basis. The latest located FYI-104 tables are effective January 1, 2025 and remained the current agency schedule when checked in 2026. The calculator uses the actual table rows. A narrative example earlier in FYI-104 still cites older $742 and 4.9% weekly-married values, so that stale example is not used as a formula oracle.

Employer cost and quarterly fee settings

New Mexico UI employer status Reimbursing employers repay benefit charges instead of applying a contribution percentage; this estimate shows $0 percentage-based UI for that preset.

YTD New Mexico UI wages before bonus

New Mexico UI wage base NMDWS lists a $34,800 taxable wage base for wages paid in 2026.

Employer's assigned total New Mexico UI rate Enter the assigned total rate. New contributing-employer industry rates range from 1.00% to 1.28% in 2026; experienced totals can include an excess-claims component.

New Mexico UI-taxable bonus percentage This affects employer cost only. New Mexico UI is not deducted from employee take-home.

YTD FUTA wages before bonus

Estimated net FUTA rate Defaults to 0.6% on the first $7,000 when the full state credit applies. Confirm timely state payments and any final credit reduction.

This paycheck includes the quarterly New Mexico workers' compensation assessment

Off by default because this is a fixed quarterly headcount fee, not a bonus percentage. When selected, the calculator deducts $2.25 from the covered employee and adds $2.55 to employer cost.

How the 2026 New Mexico bonus estimate works

Paired supplemental methods

Model federal 22% withholding with New Mexico 5.9%, or federal aggregate withholding with the applicable New Mexico table path. The federal 37% excess rule is layered only above $1 million.

Exact FYI-104 table mechanics

Use filing status and pay frequency for a combined-minus-regular calculation, or the daily and miscellaneous Table 8 schedule for a separately paid non-flat bonus.

Employee and employer costs separated

Test FICA caps, employer-only New Mexico UI, FUTA, and the optional quarterly fixed assessment with distinct inputs so employer taxes never reduce take-home.

This is a 2026 withholding estimate for an ordinary taxable cash bonus paid to a W-2 employee. Pretax benefits, retirement deferrals, wage exclusions, multiple employers, common-paymaster or successor rules, resident credits, multistate sourcing, exemption documentation, actual UI notices, and payroll-system rounding can change the paycheck. Withholding is not final income-tax liability.

New Mexico bonus withholding FAQ

Does New Mexico have a flat bonus withholding rate?

Yes, when federal withholding on the supplemental wage uses a flat percentage. FYI-104 directs employers to withhold New Mexico tax at 5.9% of the supplemental wage or fringe-benefit amount.

What if the bonus is paid with regular wages?

When aggregate treatment is used, this estimator calculates New Mexico withholding on combined taxable wages under the selected period table and subtracts the regular-pay baseline.

Why is Table 8 shown for a separate check?

FYI-104 specifically recommends its Daily or Miscellaneous Table 8 when supplemental pay, overtime, or bonuses are paid separately from normal wages and ordinary federal withholding may otherwise underwithhold for New Mexico.

Which New Mexico tables are current?

The latest located agency tables are effective January 1, 2025 and were still the current schedule when checked in July 2026. The calculator records that version explicitly and does not infer a nonexistent 2026 revision.

Why does the FYI-104 weekly example differ?

The narrative example still uses older married-weekly thresholds, but the publication's actual effective table has the updated rows. This calculator uses the table rows and flags the stale example in its research notes.

Does New Mexico have its own W-4?

No. The Department instructs an employee to complete a copy of the federal W-4 and write “For New Mexico State Withholding Only” across the top.

Does New Mexico unemployment tax reduce the bonus?

No. UI is employer-funded. The employer-cost panel applies an editable assigned total rate only to wages still inside the 2026 $34,800 wage base.

What is the workers' compensation assessment?

For July 2025 through June 2028 it is a fixed quarterly $2.25 employee fee and $2.55 employer fee per covered worker. It is off by default because it is not a percentage of bonus wages.

Is a New Mexico paid-family-leave tax included?

No. The 2025 paid family and medical leave bill died, so this calculator does not invent a 2026 payroll contribution from proposal text.

Are city or county wage taxes added?

No separate local employee wage-tax schedule is modeled. New Mexico's local-option taxes are gross-receipts taxes, which are outside an employee bonus withholding estimate.

Can this calculator gross up a promised net bonus?

Yes. Net-to-gross mode solves across federal and New Mexico method changes, the $1 monthly state threshold, Social Security cap, Additional Medicare threshold, and optional fixed fee.

Official sources checked

Primary government sources and the TimeTrex-owned CTA were checked July 27, 2026. Recheck FYI-104, the employee's New Mexico W-4 copy, exemption facts, and the employer's assigned UI notice before production payroll.
