What's different about New Mexico income tax

Six brackets

For single filers the rates are 1.5% on the first $5,500, 3.2% from $5,501, 4.3% from $16,501, 4.7% from $33,501, 4.9% from $66,501, 5.9% from $210,001 of taxable income. Joint brackets are wider at every step, with the top rate from $315,001. A single filer reaches the top rate at about $226,100 of salary.

An exemption for low and middle incomes

On top of the federal standard deduction, New Mexico allows up to $2,500 per exemption (you, your spouse, and each dependent) for low- and middle-income filers. It shrinks by 15% of AGI above $20,000 for single filers and 10% above $30,000 for joint filers, and it is gone at $36,667 single or $55,000 joint. Joint filers and heads of household with more than one dependent also deduct $4,000 for each dependent after the first.

Social Security has a hard cutoff

Social Security income is exempt if federal AGI is no more than $100,000 for single filers, $150,000 for joint filers and heads of household, or $75,000 married filing separately. There is no phase-out: a single filer with $100,001 of AGI pays tax on all the taxable benefits. Armed forces retirees can exempt up to $30,000 of retirement pay each.

Credits for working families

The Working Families Tax Credit is 25% of the federal earned income credit. The refundable child income tax credit, available through 2031, pays up to $637 per qualifying child for 2025 at AGI up to $25,000, falling as income rises. Sellers of a New Mexico business can deduct $2,500 or 40% of up to $1 million of the capital gain.

New Mexico tax credits (2025 returns)

Credits come off the tax itself, after the brackets. The calculator applies only the ones marked; the rest depend on your family and income, so subtract any you qualify for from the estimate.

Credit Amount Who gets it In calculator
Low- and middle-income exemption Up to $2,500 per exemption, phased out by $36,667 single or $55,000 joint Filers under those income limits Yes

Child income tax credit Up to $637 per child for 2025, less at higher incomes Residents with qualifying children No
