New Mexico stopped taxing Social Security for most retirees in 2022. Below $100,000 single or $150,000 joint, the benefit is exempt; above those lines, it is taxable again. The New Mexico retirement income tax still applies to pensions, IRA withdrawals, and 401(k) distributions, at graduated rates from 1.5% to 5.9%.
This guide explains the income thresholds for the Social Security exemption, what else New Mexico taxes, and what the graduated rates mean for care withdrawals.
New Mexico Retirement Income Tax at a Glance
Here is how New Mexico handles each common source of retirement money.
| Income source | How New Mexico treats it |
|---|---|
| Social Security | Exempt below $100,000 single, $150,000 joint, $75,000 MFS. Taxable above those thresholds. |
| Pensions (private and public) | Taxed. |
| IRA and 401(k) withdrawals | Taxed. |
| Senior exclusion | A separate $8,000 exemption is available to lower-income taxpayers 65 and older. |
Social Security is exempt in New Mexico for most retirees, but the break is income-tested. Below $100,000 single or $150,000 joint, your benefit is not taxed; cross those thresholds and it becomes taxable. This exemption took effect in 2022, so older guidance describing a full tax on benefits is out of date.
Pensions, IRA withdrawals, and 401(k) distributions are taxed regardless of income. A separate, smaller break exists for lower-income seniors, which we explain next.
New Mexico Retirement Income Tax: How It Works
New Mexico uses a graduated income tax running from 1.5% at the bottom to 5.9% at the top. Retirement income that is taxable, your pensions and account withdrawals, is taxed under that same schedule, with lower income taxed at the lower rates.
The headline for retirees is the Social Security exemption, and it is income-tested. The benefit is exempt below $100,000 (single), $150,000 (married filing jointly), or $75,000 (married filing separately). Above those thresholds, Social Security is taxable, so high-income retirees lose the break.
The Social Security Thresholds Are a Cliff to Watch
Pay attention to where your income sits relative to the thresholds. The exemption applies in full below the line; cross it and your Social Security becomes taxable. For a single retiree near $100,000, or a couple near $150,000, a large IRA withdrawal that pushes income over the threshold can flip the benefit from exempt to taxed.
That makes withdrawal timing matter. A retiree who would otherwise stay under $100,000 single could, by taking a big one-time 401(k) withdrawal, cross the line and expose their Social Security to tax that year. Spreading withdrawals across years can keep income under the threshold and the benefit exempt.
A Separate $8,000 Exemption for Lower-Income Seniors
New Mexico also offers a separate exemption of up to $8,000 for lower-income taxpayers 65 and older. This is distinct from the Social Security exemption and can reduce taxable income for qualifying seniors who fall under the income limits.
It is a modest, income-limited break, not a broad one. It is aimed at lower-income seniors 65 and older, so higher-income retirees generally do not qualify. Where it applies, it trims the income exposed to the 1.5% to 5.9% rates.
What This Means for Paying for Care
If you are drawing on retirement savings to pay for senior care, New Mexico taxes those withdrawals, and a large one can also push you over the Social Security thresholds.
A 401(k) or IRA withdrawal to cover assisted living is taxed at the graduated rates, up to 5.9%. If the withdrawal lifts your total income above $100,000 single or $150,000 joint, it can also make your Social Security taxable for that year, a double cost worth planning around.
Put a number on it. On a $40,000 IRA withdrawal taxed near the 5.9% top rate, the direct New Mexico tax is about $2,360, before any effect on your Social Security exemption. Keeping income under the threshold, where possible, protects the benefit from tax.
The federal side is separate. A large withdrawal still raises your federal taxable income, which can lift your federal tax and your Medicare premiums two years out. So the timing and size of care withdrawals matter on both the state and federal fronts.

Where New Mexico Stands for Retirees
New Mexico is moderately friendly to retirees, with a clear catch for higher earners. The 2022 Social Security exemption removed the tax for most retirees, below $100,000 single or $150,000 joint. For a typical retiree under those lines, the benefit is now untaxed.
The catch is the threshold. Above $100,000 single or $150,000 joint, Social Security becomes taxable again, so high-income retirees still pay on their benefit. And pensions and account withdrawals are taxed regardless, with only a small $8,000 break for lower-income seniors.
The rates work in retirees' favor at the low end. The graduated schedule starts at just 1.5% and tops out at 5.9%, so retirees with modest taxable income pay low rates.
The takeaway: New Mexico exempts Social Security for most retirees and taxes other income at moderate graduated rates. The thing to watch is the income threshold; a large care withdrawal that pushes you over it can cost you the exemption, so plan withdrawals with the line in mind.
