New Mexico state income tax calculator

Estimate New Mexico income tax using the 1.5% to 5.9% bracket schedule.

How this calculator works

Step 1 starts with the New Mexico taxable income you already calculated on your return. If you are a part-year resident or nonresident, the tool applies the New Mexico income percentage you provide to focus on New Mexico-source income.

Step 2 applies New Mexico's graduated schedule (1.5% to 5.9%) to estimate total tax.

Step 3 summarizes the effective and marginal rates so you can see how additional income would be taxed and whether your current estimate matches your expectations.
