What is New Mexico state income tax rate?
New Mexico has six brackets in 2026. For single filers: 1.5% on taxable income up to $5,500, 3.2% to $16,500, 4.3% to $33,500, 4.7% to $66,500, 4.9% to $210,000 and 5.9% above (married filing jointly: $8,000, $25,000, $50,000, $100,000 and $315,000). New Mexico starts from federal taxable income, so the federal standard deduction applies first.
