Yes
New Mexico is one of the seven states that still tax Social Security benefits in 2026 — combined with its mid-tier income rate of about 4.70%, the state-tax picture is meaningfully harder to optimize than in a no-tax / no-SS-tax state. Retirees with significant SS income should pay close attention to the bracket thresholds below.
What New Mexico taxes (and what it doesn’t)
New Mexico taxes most retirement income — including 401(k) and IRA withdrawals, pension payments, and Social Security benefits — at the state's standard income-tax rate. There are typically threshold-based exemptions that protect lower-income retirees from the SS tax, but middle-income households and above face the full bracket.
State-specific note
Taxes SS above $100k single / $150k joint (2022 reform).
A worked example
Worked example. A New Mexico retiree with $60,000 of pension and IRA withdrawals plus $30,000 of annual Social Security is taxed on the full $90,000 of income. At the approximate 4.70% effective rate, that's about $4,230/year — roughly $353/month — owed to the state.
Should you relocate?
Whether to relocate from New Mexico for tax reasons depends on the size of your retirement income and the destination state. The math typically favors staying put unless you're at $1M+ household income or planning a 20+ year retirement that amortises the move costs.

Does New Mexico tax my Social Security?
Yes. New Mexico is one of seven states that still tax Social Security benefits in 2026 — though most have income-threshold exemptions that protect lower-income retirees. Taxes SS above $100k single / $150k joint (2022 reform).
What's the effective state tax rate on my retirement income?
New Mexico's approximate effective rate for retirement-bracket income is 4.70%. For a $90k retirement income with $30k of Social Security, you'd owe roughly $4,230/year in state tax. Real liability varies with bracket structure, age-based exclusions, and pension carve-outs.
Should I relocate to New Mexico for retirement?
It depends on the size of your retirement income, the destination state's effective rate, and your moving costs. The state-tax differential alone is rarely the decisive factor for normal-income retirees. For households with $1M+ retirement income, multi-year tax-arbitrage savings can exceed $20k/year — enough to drive the decision.
Are pension benefits taxed differently in New Mexico?
Many states have specific carve-outs for pension income — particularly for public-sector pensions (teachers, firefighters, police, military). Taxes SS above $100k single / $150k joint (2022 reform). Yearfold's calculator uses an effective-rate approximation; real liability may be lower if you qualify for a pension exclusion.
Does this apply to property tax too?
No. This page covers state INCOME tax only. Property tax in New Mexico is set by local jurisdictions (county / city / school district) and varies dramatically within the state. For a complete retirement-cost picture, consult your specific county's tax assessor.
