New Mexico Income Tax: Graduated Brackets Up to 5.9%
New Mexico uses a progressive income tax system with 5 brackets. Rates range from 1.7% to 5.9%, with higher income taxed at higher rates. New Mexico exempts most Social Security income from state taxation.
Like federal taxes, New Mexico's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), New Mexico residents can face a total marginal rate of up to 42.9% on their highest dollars of income.

- 3.2% on income from $5,500 to $11,000
- 4.7% on income from $11,000 to $16,000
- 4.9% on income from $16,000 to $210,000

Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
