Worked example: $65,000 income, one child, in New Mexico

A single filer in New Mexico earning $65,000 with $7,500 of federal withholding and $2,000 of state withholding and one child under 17 is looking at roughly +$4,080 federal and −$190 from New Mexico — +$3,890 combined. The Child Tax Credit ($$2,200 non-refundable plus up to $0 refundable) does most of the work at this income.

New Mexico refund notes

New Mexico taxes income at progressive rates with a $14,600 standard deduction for single filers. State credits (like a state EITC match) are not modeled, so the state number here is conservative — if anything it understates your refund.

How We Calculate & Keep This Accurate

Federal: gross income minus the standard deduction, walked through the 2026 brackets, then the Child Tax Credit (with its phaseout), the refundable Additional Child Tax Credit and an EITC estimate. Refund = withholding + refundable credits − liability. State: the same income run through New Mexico's 2026 brackets after the state standard deduction; refund = state withholding − state liability. State credits are not modeled.

New Mexico tax refund FAQs

Common questions about 2026 refunds for New Mexico residents.

How do I estimate my 2026 refund in New Mexico?

Add up the federal tax withheld from your pay (W-2 box 2) and your New Mexico withholding (box 17), then subtract your actual tax. This calculator does both layers: federal brackets with the Child Tax Credit and EITC, plus New Mexico's state tax at its 2026 rates.

Does New Mexico have a state income tax refund?

Yes. If your employer withheld more New Mexico tax than you owe for 2026, the state refunds the difference when you file your New Mexico return.

Why is my refund smaller than last year?

Refunds shrink when withholding drops closer to your real liability, when income rises into higher brackets, or when credits phase out (the Child Tax Credit starts phasing out at $200,000 single / $400,000 joint). A smaller refund is not necessarily more tax — it can mean you kept more of each paycheck.

Is this calculator exact?

It is an estimate for a W-2 wage earner using the 2026 standard deduction. Itemized deductions, pre-tax contributions, state credits, and local taxes change the real number — use it to see the direction and rough size of your refund, then file with exact forms.
