On the ordinary retirement profile — $34,000 of Social Security and $61,000 of plan distributions — New Mexico takes $1,701 a year in state income tax.
That is the number people compare, and it is the smallest of three. Property tax adds about $2,249 on the state's $357,000 median home, and insurance another $2,800. The three together come to $6,750, placing New Mexico 18th of 50.
A note before you start. This is general education, not tax advice. Every New Mexico figure comes from this site's own fifty-state income-tax dataset and its retirement tax engine, computed for a single filer aged 70 unless stated otherwise; property tax, median home price and insurance figures come from the site's core state dataset. Rates are for tax year 2026. Property tax is assessed locally in most states, so the effective rate here is a statewide figure rather than your county's.
1. What New Mexico takes from retirement income
| Income stream | New Mexico tax |
|---|---|
| Social Security | $0 on $40,000 |
| 401(k), 403(b), 457(b), traditional IRA | $1,701 on the typical profile |
| Private employer pension | $1,184 on $50,000 |
| Public and federal government pension | $1,184 on $50,000 |
| Military retired pay | $58 on $50,000 |
On Social Security. New Mexico is one of the small group of states that still taxes Social Security in 2026, and the thresholds are the whole story. Below the threshold the federally taxable portion of benefits is exempt in full; at or above it, none of the exemption is available. It is a cliff, not a phase-out: a married couple at $149,999 exempts their benefits entirely and the same couple at $150,001 exempts nothing, which is the single most consequential fact about New Mexico retirement taxation and the one every summary drops. Note the married-filing-separately figure of $75,000 is exactly half the joint figure, so filing separately buys nothing. Thresholds are not indexed — they are fixed dollar amounts in the 2022 legislation and have not moved since, so inflation erodes the exemption every year. thresholdBasis is recorded as federal-agi because New Mexico's PIT begins from federal adjusted gross income and the statute's measure is 'adjusted gross income'; the Taxation and Revenue Department's own public page says only 'income' without qualifying it, so a reader within a few thousand dollars of the line should check the PIT-1 instructions rather than rely on this field.
On 401(k) and IRA distributions. New Mexico has NO general exclusion for 401(k), 403(b), or traditional IRA distributions. They flow through federal AGI into New Mexico net income and are taxed at the ordinary graduated rates above. What exists instead is a general age-based exemption of up to $8,000 per person age 65 or older, which is not a retirement-income exclusion at all: it reduces any kind of income, and it is itself income-limited and phases down as income rises. The $8,000 figure is the maximum, available only at low income levels, and a retiree with a substantial 401(k) draw will typically get none of it. Recorded as 'taxed' rather than 'partial-exclusion' because the exemption is not tied to the distribution.
2. The rule that decides your New Mexico bill
The asymmetry is real and it is the point. A New Mexico private pension and a New Mexico state or municipal government pension are both fully taxable; only military retirement pay gets a dedicated exemption. The armed forces retirement pay exemption is capped at $30,000 of military retirement pay per armed forces retiree, and because it attaches to the retiree rather than to the return, the amount recorded here is the same for every filing status — a married couple with two military retirees can each claim it, while a couple with one retiree gets $30,000, not $60,000. The exemption was created on a phase-in schedule ($10,000, then $20,000, then the full amount), and 2026 is well past the end of that ramp.
New Mexico taxes retirement money more heavily than its reputation as a retiree state suggests: private and public pensions and all qualified plan distributions are ordinary income, and the only categorical breaks are the Social Security threshold exemption and the military retirement exemption.
The Social Security cliff at $100,000/$150,000/$75,000 makes the marginal cost of one extra dollar of income near the line enormous. A retiree planning a Roth conversion or a large IRA withdrawal in New Mexico should model the year against those thresholds before the year ends, because crossing them re-taxes the entire benefit rather than the extra dollar.
3. What New Mexico charges at three income levels
The same state, three retirements. All figures are for a single filer aged 70.
| Profile | Income | New Mexico tax | Effective rate |
|---|---|---|---|
| Modest | $24,000 Social Security + $31,000 distributions | $383 | 0.7% |
| Typical | $34,000 Social Security + $61,000 distributions | $1,701 | 1.8% |
| Affluent | $40,000 + $100,000 + $40,000 other | $7,489 | 4.2% |
The marginal rate at the typical profile is 4.7%. That is what an extra dollar of distribution costs — a larger number than the 1.8% effective rate, and the one that matters when deciding how much to withdraw.
A married couple with $48,000 of Social Security and $62,000 of distributions pays $870.
Run your own income against New Mexico and every other state4. Property tax, and why it lands harder in retirement
An effective rate of 0.6% on the state's $357,000 median home is about $2,249 a year.
For a retiree this is a harder cost than income tax, and the reason is structural: property tax is levied on the house, while retirement income falls. A bill sized to a working income arrives every year after the income has gone.
It is also assessed locally almost everywhere, so a statewide effective rate conceals real variation between counties. Treat the figure above as the state's shape rather than as your bill.
New Mexico does have a homestead provision, and it is the one lever on this line worth understanding.
New Mexico does not have a traditional ad-valorem homestead exemption. Instead it offers a 'Head of Family' exemption under NMSA 7-37-4: up to $2,000 of the taxable (assessed) value of a primary residence is exempt for a New Mexico resident who is the head of a family (or property held in a qualifying grantor trust). Only one exemption per household; must be applied for once with the county assessor and then renews automatically. New Mexico also has a separate, larger property tax limitation for qualifying low-income seniors (65+) and disabled residents that freezes assessed value, which is distinct from this exemption.
Two things about homestead rules catch people out after a move. They almost always require the property to be your primary residence, which a snowbird splitting the year has to be able to demonstrate. And several states require an application to the county rather than granting it automatically — a benefit you qualify for and never claimed is worth nothing.
5. Insurance, the line nobody prices
Average home insurance in New Mexico: $2,800 a year — 28th cheapest of the fifty states.
This is the line almost no retirement comparison includes, and across the country it varies more than income tax does: from Hawaii's $900 to Florida's $8,375, a ninefold spread.
For a retiree it behaves like a second property tax. It rises independently of income, a fixed-income household absorbs the whole increase, and it is a condition of the mortgage if you still have one.
6. What retiring in New Mexico actually costs
Income tax on the typical retirement profile, plus property tax and insurance on each state's own median home. New Mexico is shown against its own neighbours in the ranking, and against the extremes.
| State | Income tax | Property tax | Insurance | Total |
|---|---|---|---|---|
| Wyoming | $0 | $2,083 | $1,900 | $3,983 |
| Nevada | $0 | $2,489 | $2,025 | $4,514 |
| Ohio | $961 | $3,339 | $2,080 | $6,380 |
| North Dakota | $0 | $2,888 | $3,510 | $6,398 |
| Pennsylvania | $0 | $4,420 | $2,045 | $6,465 |
| New Mexico | $1,701 | $2,249 | $2,800 | $6,750 |
| Kentucky | $929 | $2,099 | $3,795 | $6,823 |
| Washington | $0 | $5,191 | $1,650 | $6,841 |
| Indiana | $1,770 | $2,128 | $2,985 | $6,883 |
| Minnesota | $4,937 | $3,750 | $3,615 | $12,302 |
| Connecticut | $4,475 | $8,779 | $2,690 | $15,944 |
New Mexico comes to $6,750, 18th of 50.
Income tax is 25% of that total. It is the line every comparison leads with and, here, not the largest of the three.
One large caveat, and it matters. Each row uses that state's own median home, and those differ a great deal. So this compares the typical house in each state, not the same house in each state — buying below a state's median improves its figure materially.
7. No special treatment, and what that simplifies
New Mexico gives retirement income no special treatment. Distributions are taxed as ordinary income at the ordinary schedule, with no age trigger, no source distinction and no phase-out to plan around. New Mexico has NO general exclusion for 401(k), 403(b), or traditional IRA distributions. They flow through federal AGI into New Mexico net income and are taxed at the ordinary graduated rates above. What exists instead is a general age-based exemption of up to $8,000 per person age 65 or older, which is not a retirement-income exclusion at all: it reduces any kind of income, and it is itself income-limited and phases down as income rises. The $8,000 figure is the maximum, available only at low income levels, and a retiree with a substantial 401(k) draw will typically get none of it. Recorded as 'taxed' rather than 'partial-exclusion' because the exemption is not tied to the distribution. That simplicity cuts both ways. There is nothing to lose by withdrawing more in one year than another, and nothing to gain by waiting — which makes New Mexico an unusually clean state to plan a withdrawal order in, even though it is not a generous one.
8. What a Roth conversion costs in New Mexico
Converting $50,000 to a Roth costs an extra $4,073 in New Mexico tax — 8.1 cents on the dollar.
| Converted | Extra New Mexico tax | Cost per dollar |
|---|---|---|
| $50,000 | $4,073 | 8.1% |
| $100,000 | $6,523 | 6.5% |
These are computed, not read off the bracket table, which matters because a conversion large enough to be worth making usually leaves the bracket it started in.
The state's share is the part you can move. Convert in a year you are resident somewhere with no income tax and it is zero; convert here and it is 8.1%. The federal tax is due either way.
9. What part-time work costs here
$20,000 of part-time work costs an extra $2,603 in New Mexico tax — an effective 13% on the earnings.
Compare that with the 8.1% a Roth conversion costs. Wages are the more expensive dollar here.
Two federal rules apply on top and neither depends on your state. Earnings can raise the taxable share of Social Security, and claiming before full retirement age exposes you to the federal earnings test.
10. The order to draw your accounts in
The order you draw accounts in is worth real money, and the right order depends on the state.
New Mexico applies the same treatment whenever you withdraw, so the order is a federal question rather than a state one — with the exception that the marginal rate is 4.7%, and a year of unusually high withdrawals pays that on the excess.
Smoothing withdrawals across years therefore beats lumping them, modestly. Take a large one-off distribution in a single year and it climbs the bracket schedule; spread the same amount over three and more of it stays low.
Required minimum distributions overrule all of this from 73 onward. Once they begin you must take the calculated amount whether the order suits you or not, which is the argument for drawing down or converting the pre-tax balance in the years before.
11. Or move across the state line
For most people the real alternative to New Mexico is not Wyoming — it is the state on the other side of the line, near the same family, the same doctors and the same weather.
| State | Income tax | Property tax | Insurance | Total | Rank |
|---|---|---|---|---|---|
| Arizona | $1,131 | $2,152 | $2,135 | $5,418 | 4 |
| New Mexico | $1,701 | $2,249 | $2,800 | $6,750 | 18 |
| Colorado | $2,416 | $2,871 | $3,312 | $8,599 | 33 |
| Utah | $4,228 | $2,672 | $1,810 | $8,710 | 34 |
| Texas | $0 | $4,830 | $4,915 | $9,745 | 37 |
| Oklahoma | $1,750 | $1,994 | $7,255 | $10,998 | 41 |
Arizona is the cheapest of the group at $5,418, $1,332 below New Mexico. Whether that is worth a move is a question about your life rather than your spreadsheet — but it is the comparison worth running, because it is the one you could actually act on.
One thing this table cannot show is the county. Property tax is set locally, and the spread inside a single state is routinely wider than the gap between two neighbouring states. A border move to a cheaper state and an expensive county can leave you worse off.
12. If you are moving to New Mexico from somewhere else
The eight most populous states people leave, measured against New Mexico on the same three lines.
| Moving from | Their total | New Mexico | Difference |
|---|---|---|---|
| California | $9,520 | $6,750 | $2,770 cheaper |
| Texas | $9,745 | $6,750 | $2,995 cheaper |
| Florida | $11,690 | $6,750 | $4,940 cheaper |
| New York | $10,287 | $6,750 | $3,537 cheaper |
| Pennsylvania | $6,465 | $6,750 | $285 dearer |
| Illinois | $8,391 | $6,750 | $1,641 cheaper |
| Ohio | $6,380 | $6,750 | $370 dearer |
| Georgia | $6,033 | $6,750 | $717 dearer |
New Mexico is cheaper than 5 of these eight. Which means the answer genuinely depends on where you are starting from.
A move is not free, and this table does not price it. Transaction costs on both houses run to several per cent of the sale price, and at typical values that is often more than the first two or three years of the saving.
New Mexico charges no transfer tax on the purchase, which is one closing cost you will not meet here and do meet in most states. Closing costs here run about 1.1% to 2.9% of the price — $3,927 to $10,353 on the median home, which is the real entry fee for the annual saving this article has been describing.
13. What New Mexico does not exempt you from
The federal system, entirely. This is the commonest misunderstanding about state retirement taxation, and it is worth stating plainly.
Required minimum distributions still apply. The amount is federal — your prior-year balance divided by an IRS life expectancy factor — and identical in all fifty states. A state changes what the distribution costs you, not whether you must take it.
Social Security is still federally taxable, on the federal provisional-income calculation, whatever your state does with it.
IRMAA still applies, with its two-year lag. A large conversion or distribution raises a Medicare premium two years later regardless of address.
And capital gains are still federally taxed. What New Mexico adds on top is a separate question from what the federal system takes.
14. Establishing that you actually live here
Any state tax advantage is worth nothing until New Mexico is your domicile, and the state you left may disagree about when that happened.
High-tax states audit departing residents. The question is not whether you own a home here; it is whether you genuinely abandoned the old domicile. Days spent in each state, voter registration, vehicle registration, where your doctors are and where you claim a homestead all bear on it.
The snowbird case is the risky one. Splitting the year between two states while keeping a home in both is exactly the profile a residency audit is built for. If a plan depends on the saving, count the days from the first year rather than reconstructing them afterwards.
15. Who New Mexico actually suits
It suits an affluent retiree least. At the affluent profile the bill is $7,489, and whatever exclusion helps a modest income has stopped helping by then.
16. What to check before you decide
Get your county's actual property tax rate, not the state average. Property tax is levied locally almost everywhere, and the spread inside a state is often wider than the spread between states.
Get a real insurance quote on a real address. $2,800 is the state average; construction, roof age and exposure move it a long way.
Work out your own income tax rather than using the profile above. $95,000 split one way is not $95,000 split another, and in New Mexico the mix between Social Security and distributions changes the answer.
And check what your current state actually charges you before assuming it is worse. On these three lines the ranking surprises people in both directions.
Frequently asked questions
Does New Mexico tax Social Security? No. New Mexico is one of the small group of states that still taxes Social Security in 2026, and the thresholds are the whole story. Below the threshold the federally taxable portion of benefits is exempt in full; at or above it, none of the exemption is available. It is a cliff, not a phase-out: a married couple at $149,999 exempts their benefits entirely and the same couple at $150,001 exempts nothing, which is the single most consequential fact about New Mexico retirement taxation and the one every summary drops. Note the married-filing-separately figure of $75,000 is exactly half the joint figure, so filing separately buys nothing.
Does New Mexico tax 401(k) or IRA withdrawals? New Mexico has NO general exclusion for 401(k), 403(b), or traditional IRA distributions. They flow through federal AGI into New Mexico net income and are taxed at the ordinary graduated rates above. What exists instead is a general age-based exemption of up to $8,000 per person age 65 or older, which is not a retirement-income exclusion at all: it reduces any kind of income, and it is itself income-limited and phases down as income rises. The $8,000 figure is the maximum, available only at low income levels, and a retiree with a substantial 401(k) draw will typically get none of it.
What about pensions — private, government, or military? A $50,000 pension costs $1,184 if private, $1,184 if a government pension, and $58 if military retired pay. Those differences are the state's own policy, not an accident of the arithmetic.
What does retiring in New Mexico actually cost? Income tax of $1,701 on the typical profile, plus about $2,249 of property tax and $2,800 of insurance on the median home — $6,750, which is 18th of 50.
Is New Mexico a cheap state to retire in? On these three lines it ranks 18th of 50. Whether that makes it cheap for you depends far more on the house than on the tax code.
What does a Roth conversion cost in New Mexico? An extra $4,073 in state tax on $50,000 converted, and $6,523 on $100,000. That is 8.1% of the amount converted, on top of the federal tax.
Does part-time work get taxed differently from my 401(k) withdrawals? $20,000 of part-time earnings costs $2,603 in state tax, an effective 13%.
Would a neighbouring state be cheaper than New Mexico? Arizona is the cheapest of New Mexico and its neighbours at $5,418 against New Mexico's $6,750.
Do required minimum distributions change if I move here? No. The required amount is a federal calculation and identical in every state. What changes is what the distribution costs once taken.
Does this article include local income tax? No local income tax applies to retirement income in New Mexico on the figures used here.
Will New Mexico's treatment still apply in ten years? State legislatures revise retirement taxation regularly — several states have changed theirs in the past three years. Figures here are for tax year 2026 and are worth re-checking before a move.
