Social Security Benefits
New Mexico exempts Social Security benefits for most taxpayers.
Eligibility depends on income level, but many retirees do not pay state tax on Social Security.
Example:
If your income falls below the state’s exemption threshold and you receive $28,000 in Social Security benefits, that amount may not be included in your New Mexico taxable income.
Pension Income
Pension income is generally taxable in New Mexico unless a deduction applies.
This includes:
• Private employer pensions
• Government pensions
• Federal civil service pensions
• Military retirement pay
New Mexico offers a retirement income deduction for taxpayers age 65 or older, subject to income limits.
IRA Withdrawals
Traditional IRA withdrawals are taxable in New Mexico because they are included in federal taxable income.
This includes:
• Regular withdrawals
• Required Minimum Distributions
• Early withdrawals
However, eligible retirees may offset some of this income using the state’s retirement income deduction.
Roth IRA qualified distributions are generally not taxable because they are not included in federal taxable income.
401(k) and 403(b) Withdrawals
401(k) and 403(b) distributions are generally taxable in New Mexico if taxable federally.
This includes:
• Periodic withdrawals
• Lump-sum distributions
These amounts are taxed under the progressive brackets unless reduced by the retirement income deduction.
Retirement Income Deduction
New Mexico provides a retirement income deduction for taxpayers age 65 or older.
The deduction amount depends on total income and filing status. Income limits apply, and the deduction phases out at higher income levels.
This deduction can significantly reduce state taxable income for moderate-income retirees.
What Income Is Still Taxed?
New Mexico generally taxes:
• Wages and salaries
• Business income
• Rental income
• Interest and dividends
• Capital gains
Retirement income is included unless reduced by exemptions or deductions.
Marginal vs Effective Rate
Your marginal rate depends on which bracket your top income falls into.
Your effective rate will be lower than your highest bracket because only a portion of your income is taxed at the top rate.
Planning withdrawals carefully can help manage which bracket your income falls into.
Planning Considerations
• Social Security may be exempt depending on income
• Retirement income deductions can reduce taxable income
• IRA and 401(k) withdrawals are generally taxable
• Managing total income can help preserve eligibility for deductions
• Roth withdrawals may reduce state taxable income
Income thresholds matter in New Mexico, so coordination of withdrawals is important.
💻 Electronic Filing Recommendation
E-filing your New Mexico return is recommended:
• Automatic progressive bracket calculations
• Built-in retirement income deduction handling
• Reduced math errors
• Faster processing
Tax software helps apply income-based exemptions correctly once your information is entered.

New Mexico taxes pensions, IRA withdrawals, and 401(k) distributions under a progressive income tax system in 2026.
