Minnesota for retirees: Social Security below the line, pensions and IRAs taxed in full

Minnesota taxes retirement income, with one large exception and two narrow ones. The large exception is Social Security: since 2023, a retiree with adjusted gross income of $110,780 or less on a joint return, or $86,410 single or head of household, subtracts every dollar of federally taxable Social Security on Schedule M1M and pays Minnesota nothing on it. Above that line the subtraction fades out by 10% for each $4,000 of AGI and is gone at $150,780 joint or $126,410 single. Pensions, traditional IRA withdrawals, 401(k) and 403(b) distributions, annuities and Roth conversions have no such subtraction. They are taxed at the regular graduated rates, 5.35% to 9.85%, at any age and in any amount. The narrow exceptions are military retirement pay, which is subtracted in full, and a capped subtraction for public pensions earned in jobs that did not also pay into Social Security. What Minnesota gives seniors beyond that is an extra $1,600 or $2,000 on the standard deduction at 65, and relief on the property tax bill that is claimed on a separate return.

The practical result is that most retired couples living on Social Security and a modest pension or IRA pay little Minnesota tax. The retirees who feel it are the ones with large pensions or IRA balances, and the ones who take a big withdrawal or conversion in a single year, because the withdrawal is taxed and it can also pull the Social Security subtraction out from under them.

What is taxed and what is not

Capital gains are ordinary income in Minnesota. There is no preferential rate and no exclusion, though the federal exclusion on the sale of a home flows through, because the excluded gain never enters AGI.

The Social Security subtraction

Minnesota uses the federal figure: the taxable amount of Social Security on line 6b of Form 1040, which can be anything from zero to 85% of the benefit. If none of your Social Security is taxed federally, there is nothing to subtract and nothing to tax. If some of it is, the Minnesota question is simply where your AGI stands.

At or below $110,780 on a joint return ($86,410 single or head of household, $55,390 married filing separately), the whole taxable amount comes off. Above the line, the subtraction is reduced by 10% for each $4,000 of AGI, or any part of $4,000, over it; married filing separately uses $2,000 steps. The steps are blunt. A couple with AGI of $110,781 is one dollar over and loses 10% of the subtraction. At $114,781 they lose 20%. At $150,780 the subtraction is zero. Because AGI includes the taxable Social Security itself, a couple with $30,000 of taxable benefits and $100,000 of pension and IRA income is already at $130,000 and keeps only half.

Filers over the line may use the older alternative method instead, a fixed maximum of $5,840 joint, $4,560 single or head of household, $2,920 married separate, phased out above provisional income of $88,630, $69,250 and $44,315. Those figures are not indexed and the method rarely helps anyone whose AGI is over the simplified line; the software checks it, and it is worth a look only when provisional income is near those thresholds.

Pensions, IRAs and the age-65 additions

There is no pension exclusion of any size and no age at which retirement income stops being taxed. A $40,000 pension is taxed the same as $40,000 of wages. What a retiree gets instead is the extra standard deduction: $1,600 for each spouse 65 or older on a joint return, so $33,800 for a couple both 65 or older against the ordinary $30,600, and $2,000 for a single filer or head of household, so $17,300 against $15,300. Blindness adds the same amounts again.

Schedule M1R, the Age 65 or Older/Disabled Subtraction, exists but reaches few people with a pension. It starts at $12,000 for a couple both 65 or older ($9,600 single), is reduced by every dollar of nontaxable Social Security and by half of AGI over $18,000 ($14,500 single), and is available only when AGI is under $42,000 joint or $33,700 single. It helps a retiree with small Social Security and a small pension, and almost no one else.

Roth conversions: taxed, and sometimes taxed twice over

A Roth conversion is a traditional IRA distribution that is immediately deposited in a Roth. Federally it is taxable in the year of the conversion, and in Minnesota it is in federal AGI on line 1 of Form M1 with nothing to take it back out. The conversion is taxed at the regular rates. For a couple whose other income already fills the 5.35% bracket, that means 6.8% on most of the converted amount, and 7.85% once taxable income passes $193,480.

The second cost is the one people miss. The conversion raises AGI, and AGI is what switches the Social Security subtraction off. A couple at $90,000 of AGI who convert $50,000 land at $140,000, past the $110,780 line by $29,220, which is eight steps of $4,000 or part of one, so 80% of their Social Security subtraction disappears for that year. The Minnesota tax on the conversion is then the tax on the $50,000 plus the tax on the Social Security that came back into income. For a couple with $30,000 of taxable benefits, that is another $24,000 of taxable income, and the effective Minnesota rate on the conversion is closer to 10% than 6.8%.

Three ways to soften it. Convert in amounts that keep AGI at or under $110,780, which for many couples means $20,000 to $30,000 a year rather than one large conversion. Convert in a year before Social Security starts, when there is no subtraction to lose. Or accept the one-year loss as the price of tax-free Roth withdrawals later, remembering that qualified Roth withdrawals are never in AGI, so a retiree who has converted enough can later take Roth money for a large expense without disturbing the subtraction.

The federal senior deduction, and why it does not help here

The $6,000 federal deduction for people 65 and older, in effect for 2025 through 2028, comes off after adjusted gross income, alongside the federal standard deduction. Minnesota starts from AGI, so the deduction never reaches Form M1 and no add-back is needed, because nothing was taken out. The same is true of the federal extra standard deduction for age. Minnesota’s own age break is the $1,600 or $2,000 addition to its standard deduction, worth $86 to $107 of tax at the 5.35% rate, plus the Schedule M1R subtraction for the few who qualify. The 2026 tax bill did not add a Minnesota senior deduction.

Military and public pensions

Military retirement pay, including survivor benefit plan payments, is subtracted in full on Schedule M1M. The retiree may instead claim the nonrefundable Credit for Past Military Service of up to $750 on Schedule M1C, which is income-limited and worth choosing only when the pension is small; the software compares the two. Active-duty pay and National Guard and Reserve pay are subtracted as well.

The Qualified Public Pension Subtraction on Schedule M1QPEN is for retirees whose government job did not pay into Social Security, so that the pension is their Social Security. It covers basic members of PERA, the PERA Police and Fire plan, the Teachers Retirement Association and St. Paul Teachers fund, the State Patrol fund, the legislators’ plan and the local government correctional plan, and federal and other states’ plans on the same terms where the service earned no Social Security credit. Coordinated members, whose job earned both a pension and Social Security, do not qualify, and neither do FERS retirees. Someone who paid into Social Security for part of a career subtracts only the share of the pension earned in the years that did not. The maximum is $27,690 on a joint return and $13,850 for everyone else, and it phases out above the same AGI lines as the Social Security subtraction, $110,780 joint and $86,410 single, at 10% for each $2,000. A retired teacher on a $50,000 TRA pension with no other income subtracts $13,850 and is taxed on the rest.

Property tax relief, on a separate return

None of the property tax help for seniors is claimed on Form M1. Homeowners file Form M1PR, the Homestead Credit Refund, due August 15, a separate return with its own household income test that counts Social Security and all retirement income in full, whether or not the income tax touched them. For the 2026 return filed in 2027, total household income must be under $147,110 (verify); the maximum refund for 2026 is to come, and the 2025 maximum was $3,480 with a $142,490 income limit. A homeowner 65 or older subtracts $5,300 from household income before applying the table, and the refund rises as income falls. The one-time 14.88% increase enacted in 2026 applied to the refund on taxes payable in 2026, the return filed by August 2026, and does not repeat for taxes payable in 2027.

The special refund on Schedule M1PR-SR, for a net property tax that rose more than 12% and at least $100 in a year, has no income limit and pays up to $1,000. The Senior Citizens’ Property Tax Deferral lets a homeowner 65 or older with household income of $96,000 or less pay no more than 3% of income in property tax while the state defers the rest as a lien; apply to the county by November 1. Renters claim the Renter’s Credit on the income tax return instead, up to $2,780 for household income under $79,330, with the landlord’s Certificate of Rent Paid.

Estate tax

Minnesota has an estate tax with a $3,000,000 exclusion that is not indexed and does not transfer between spouses. Rates run from 13% to 16% on the amount above it, and taxable gifts made within three years of death are pulled back into the Minnesota estate. A couple with a paid-off house, two IRAs and a brokerage account can be over the line without ever having thought about estate tax, since the federal exemption is more than four times higher. A will that leaves everything to the surviving spouse postpones the question; it does not avoid it, because the exclusion of the first spouse to die is lost. See Gift and estate taxes for the federal side.

Withholding

Pension administrators and IRA custodians will withhold Minnesota tax on request, and since the income is taxed in full, retirees should usually let them. Minnesota expects estimated payments from anyone who will owe $500 or more after withholding and credits, a lower trigger than the federal $1,000, and charges a penalty on Schedule M15 when the quarterly payments fall short. The Social Security Administration does not withhold state tax at all, which is fine for the retiree under the subtraction line and a problem for the one over it.
