Does New Mexico Tax Social Security?
Yes, with income limits that spare many retirees. Updated for 2026.
Verdict: yes, New Mexico taxes Social Security benefits in 2026, but not for everyone. Income thresholds, deductions or credits mean many retirees here pay nothing on their benefits.
How New Mexico treats benefits
Exempts benefits below income thresholds that cover most retirees.
New Mexico is one of only eight states that tax Social Security at all in 2026. The other seven are Colorado, Connecticut, Minnesota, Montana, Rhode Island, Utah and Vermont. Being on that list is not the same as owing tax. Every one of the eight shields lower and middle incomes to some degree, and a retiree living mainly on benefits often owes nothing at all.
What usually triggers the tax is other income sitting alongside your benefits: a pension, withdrawals from a retirement account, or wages from continued work. Check the current thresholds with the New Mexico revenue department before you assume either way.
Federal tax still applies
This is the part people miss. Whatever your state does, up to 85% of your Social Security benefits can be subject to federal income tax, depending on your provisional income, which is your other income plus half your benefits.
Far more retirees pay federal tax on benefits than pay any state tax on them. If you are budgeting, that is the number that matters.
What actually moves the needle in New Mexico
State tax treatment is a small factor next to when you claim. Claiming at 62 pays 70% of your full benefit for life. Waiting until 70 pays 124%. That gap dwarfs any state tax difference, and it applies wherever you live.

If you are weighing a move for tax reasons, benefits are rarely the deciding factor. Property taxes, healthcare access and housing costs matter more. Best Life Index compares New Mexico on cost of living overall.
