How New Mexico state tax withholding works
New Mexico taxes wage income, so your employer withholds New Mexico income tax from each paycheck in addition to federal tax. You tell your employer how much to withhold on Federal Form W-4 (New Mexico uses the federal W-4 (no separate state form)), the state’s counterpart to the federal Form W-4.
For 2026, New Mexico uses graduated tax rates. Each rate applies only to the income within its band — the single-filer schedule is:
| Rate | Taxable income over |
|---|---|
| 1.5% | $0 |
| 3.2% | $5,500 |
| 4.3% | $16,500 |
| 4.7% | $33,500 |
| 4.9% | $66,500 |
| 5.9% | $210,000 |
New Mexico’s standard deduction is $16,100 (single) and $32,200 (married filing jointly).

New Mexico vs. federal withholding
Your New Mexico and federal withholding are figured separately. Federal withholding follows the IRS Publication 15-T tables and your Form W-4; New Mexico withholding follows the state’s own rates and your Federal Form W-4. Getting one right doesn’t guarantee the other — this calculator handles both so you don’t owe a surprise bill to either the IRS or New Mexico.
Important New Mexico notes
- New Mexico withholds based on the federal W-4 and its own percentage-method tables.
