New Mexico Retirement Income Tax: What You Will Actually Owe

The honest answer most retirement community marketing won’t give you

New Mexico is not a zero-income-tax state. It is not even a retirement-income-exempt state. Pensions, IRA withdrawals, and 401(k) distributions are fully taxable in New Mexico at graduated rates up to 5.9%. Social Security has an exemption — but only for incomes below specific thresholds. Before buying in Albuquerque or anywhere in New Mexico, you need to know this clearly.

New Mexico Income Tax Brackets (2025)

Taxable Income (Single)	Taxable Income (MFJ)	NM Rate
Up to $5,500	Up to $8,000	1.5%
$5,501–$11,000	$8,001–$16,000	3.2%
$11,001–$16,000	$16,001–$24,000	4.3%
$16,001–$210,000	$24,001–$315,000	4.7%
$210,001–$315,000	$315,001–$420,000	4.9%
Over $315,000	Over $420,000	5.9%

Social Security: Exempt Below These Thresholds

New Mexico enacted a Social Security income tax exemption in 2022. Your benefits are fully exempt from NM income tax if:

Single filers: MAGI under $100,000. Married filing jointly: MAGI under $150,000. Married filing separately: MAGI under $75,000.

If your income exceeds these thresholds, Social Security benefits are added back into your NM taxable income and taxed at the rates above. Approximately 86% of NM seniors qualify for the exemption — but a couple with $80,000 in IRA income plus $40,000 in Social Security has MAGI of $120,000+ and loses the exemption entirely.

The scenario that surprises most buyers: A retired couple with $90,000/year in IRA and pension income plus $36,000 in Social Security. Their MAGI is $126,000 — above the $150,000 MFJ threshold? Actually, they just barely qualify. But add even $25,000 more in distributions and both SS and the full $115,000+ is taxable. At NM’s 4.7% rate on most of that income, the couple owes approximately $5,400 in NM income tax annually. That erodes much of the property tax advantage vs. a Texas community.

Retirement Income Deduction (Age 65+)

Taxpayers 65 and older may deduct up to $8,000 of retirement income from NM taxable income — but only if household AGI is under $28,500 (single) or $51,000 (married filing jointly). Most Mirehaven or Alegria buyers will not qualify for this deduction given typical home prices and the incomes required to purchase there.

The Honest Net Position

NM’s property taxes are genuinely low — among the lowest effective rates in the Sun Belt. At $500,000 in Bernalillo County, you pay approximately $4,200/year in property taxes. A Texas buyer at $500K in a major metro pays $8,000–$10,000. That’s a $4,000–$6,000 annual property tax advantage for NM.

But a Texas buyer pays zero income tax on any retirement income. An NM buyer with $70,000 in annual retirement distributions (excluding SS) pays approximately $3,290 in NM income tax. The net advantage over Texas is reduced to approximately $700–$2,700 per year depending on income. For buyers with very low retirement income, NM wins on total taxes. For buyers with substantial IRA income, it is closer than most people assume.

Who benefits most from NM: Retirees whose primary income is Social Security plus a modest IRA draw below $100,000 MAGI. The SS exemption applies, property taxes are low, and the income tax bite is minimal. Retirees with $100,000+ in annual distributions are better served running a detailed comparison with a tax advisor before committing.
