Does Minnesota Tax Social Security? (w/Examples) + FAQs

This article reflects federal rules and Minnesota rules as of June 2026 and covers tax year 2025 (the return you file by April 15, 2026). Tax law changes — confirm current figures before you file.

Quick Answer

It depends on your income. For tax year 2025, Minnesota does not tax Social Security benefits if your federal adjusted gross income is at or below $108,320 (married filing jointly) or $84,490 (single or head of household). Above those lines, part of your benefits becomes taxable.

Minnesota is one of the shrinking number of states that still reach into Social Security checks, but most retirees here never pay a dime of state tax on those benefits. The state offers an income-tested “subtraction” that wipes out the tax for lower- and middle-income filers, and only phases in for higher earners — which means the exact number on your tax return decides whether you owe anything at all.

The stakes are real and the timing matters. According to Minnesota House Research, about 29.3 percent of resident returns that report Social Security benefits will pay at least some Minnesota tax on them in tax year 2025 — so roughly 7 in 10 pay nothing. Here is what you will learn:

How Minnesota Taxes Social Security: The Core Mechanics

Minnesota does not tax Social Security as a separate, stand-alone item. Instead, the state starts from your federal adjusted gross income (FAGI), which already includes whatever portion of your benefits the IRS taxes. Minnesota then lets you subtract some or all of that federally taxable amount back out before calculating state tax. That subtraction is the whole ballgame.

The plain-English version is this: the federal government decides how much of your Social Security is taxable (between 15 percent and 100 percent is excluded federally, depending on income), and that taxable slice flows into your Minnesota return. Minnesota’s Social Security Benefit Subtraction then removes part or all of that slice from your state taxable income. If your income is low enough, the subtraction equals 100 percent of the taxable benefits, and your state tax on Social Security is zero.

The consequence of misunderstanding this is expensive. Minnesota’s income tax rates run from 5.35 percent to 9.85 percent, per SmartAsset’s Minnesota analysis, so every dollar of benefit that stays taxable is taxed at your ordinary state rate. A retiree who fails to claim the subtraction — or assumes Minnesota copies the 32 states that fully exempt benefits — can overpay by hundreds or thousands of dollars.

The federal starting point you cannot skip

Federal law uses “provisional income” to decide how much of your benefit is taxable. Provisional income equals your FAGI minus taxable Social Security, plus 50 percent of your benefits, plus tax-exempt interest, as the House Research report lays out. Below $32,000 (married) or $25,000 (single) of provisional income, none of your benefit is federally taxable — and therefore none is taxable in Minnesota either.

The consequence is that very low-income retirees never face this issue. About 99 percent of the Social Security benefits actually taxed by Minnesota belong to filers with at least $75,000 of federal AGI, the state’s modeling shows. The misconception to drop is that “Minnesota taxes Social Security” means everyone pays — it does not.

Why Minnesota taxes benefits at all

Minnesota historically conformed to the federal treatment adopted in 1983, when Congress first taxed up to 50 percent of benefits to shore up Social Security’s solvency. Lawmakers cited horizontal equity — the idea that two retirees with the same income should pay the same tax regardless of where the income comes from. That reasoning still anchors the current law.

The practical takeaway: Minnesota built a generous income-tested subtraction in 2017 and dramatically expanded it in 2023, rather than a flat exemption. So your job is not to ask “does Minnesota tax Social Security,” but “does Minnesota tax my Social Security at my income.”

The 2025 Minnesota Subtraction Thresholds (Exact Numbers)

For tax year 2025, the subtraction begins to phase out above specific AGI lines, and your benefits become fully taxable only at much higher income. These figures come directly from Minnesota House Research and the Department of Revenue.

Here is the full structure for tax year 2025, by filing status:

Filing status and benefit treatment	2025 federal AGI range
Married joint — Social Security fully exempt	$108,320 or less
Married joint — some benefits taxed by Minnesota	$108,321 to $144,320
Married joint — all federally taxable benefits taxed by Minnesota	$144,321 or greater
Single or head of household — fully exempt	$84,490 or less
Single or head of household — some benefits taxed	$84,491 to $120,490
Single or head of household — all federally taxable benefits taxed	$120,491 or greater
Married filing separately — fully exempt	$54,160 or less
Married filing separately — some benefits taxed	$54,161 to $72,160
Married filing separately — all federally taxable benefits taxed	$72,161 or greater

The phase-out math is mechanical. For most filers, the subtraction drops by 10 percent for each $4,000 of AGI (or any fraction of $4,000) above the threshold; married-separate filers lose 10 percent per $2,000, per the Instead deadline guide. So a married couple at $115,000 of AGI sits $6,680 over the $108,320 line — that is two increments of $4,000 — and keeps an 80 percent subtraction.

The consequence of these brackets is a “zig-zag” tax that rises as income climbs through the phase-out zone. Miss the threshold by even one dollar and you start losing the exemption, so year-end income timing genuinely matters for retirees near the line.

What income counts toward the threshold

The threshold uses federal AGI, not just your Social Security. That means IRA and 401(k) withdrawals, pension payments, wages, interest, dividends, and capital gains all push you toward — and possibly over — the line. A large one-time Roth conversion or stock sale can vault a normally-exempt retiree into the taxable zone for that single year.

The action step is to project your AGI before December 31. If you are close to your filing-status threshold, spreading withdrawals across years or timing a Roth conversion can preserve the full subtraction and save real tax dollars.

Which Situation Applies to You?

Your answer depends almost entirely on three things: your filing status, your total income, and your age. Use this quick branch to find the part of this guide that fits you.

Married joint, AGI $108,320 or less (single/HOH $84,490 or less): Your Social Security is fully exempt in Minnesota for 2025. Read the worked examples to confirm, then claim the subtraction on Schedule M1M.
Income in the phase-out zone: You owe Minnesota tax on part of your benefits. The phase-out examples below show how to estimate your taxable slice.
High income (married above $144,320; single above $120,490): All of your federally taxable benefits are taxed by Minnesota. Focus on planning moves and the federal senior deduction.
Age 65 or older: You may also claim the new federal senior deduction, which lowers your federal tax but does not change Minnesota’s subtraction — see that section.
Thinking of moving: Compare Minnesota with South Dakota and Wisconsin in the state-comparison section before you decide.

Worked Examples With Real Dollars

Numbers make this concrete. Each example assumes tax year 2025 and uses the published thresholds. These are illustrations, not a substitute for running your actual return.

Example 1 — Single retiree, fully exempt

Margaret, single, age 68, lives in Duluth. She receives $21,700 in Social Security (Minnesota’s average benefit) and takes $20,000 from her IRA, for a federal AGI around $34,000. Because her AGI is far below the $84,490 single threshold, her entire federally taxable benefit qualifies for a 100 percent Minnesota subtraction.

Federally taxable Social Security flowing into Minnesota: assume $5,000.
Minnesota subtraction: 100 percent, or $5,000.
Minnesota tax on her Social Security: $0.

Margaret pays Minnesota tax on her IRA money, but nothing on her Social Security. This matches the state’s finding that a single filer with an average benefit owes no tax until total income reaches about $38,700.

Example 2 — Married couple in the phase-out zone

David and Susan, married filing jointly, both 70, live in Bloomington. They have $115,000 of federal AGI, including $30,000 of Social Security, of which $25,500 is federally taxable (85 percent). Their AGI is $6,680 over the $108,320 threshold, which is two $4,000 increments, so they lose 20 percent of the subtraction.

Federally taxable benefits: $25,500.
Subtraction allowed: 80 percent × $25,500 = $20,400.
Benefits still taxed by Minnesota: $25,500 − $20,400 = $5,100.
At roughly a 7.85 percent marginal Minnesota rate, state tax on benefits ≈ $400.

If David and Susan trimmed their AGI to $108,320 — say, by delaying a $7,000 IRA withdrawal — they would recover the full 100 percent subtraction and erase that $400.

Example 3 — High-income couple, fully taxed

Robert and Linda, married filing jointly, both 67, live in Edina. Their AGI is $160,000, including $40,000 of Social Security with $34,000 federally taxable. Because $160,000 exceeds the $144,320 ceiling, all of their federally taxable benefits are subject to Minnesota tax — the subtraction is fully phased out.

Federally taxable benefits: $34,000.
Minnesota subtraction: $0.
Benefits taxed by Minnesota: $34,000.
At a 9.85 percent top marginal rate, state tax on benefits ≈ $3,349.

The largest possible state benefit from a full exemption for a couple with average benefits is about $3,633, per House Research — close to Robert and Linda’s situation, which shows why high earners feel this most.

Three Common Scenarios at a Glance

The tables below translate the rules into outcomes. Each shows a typical filer and the Minnesota result for tax year 2025.

Scenario A — Modest-income single filer

Your situation	Minnesota result
Single, AGI $50,000, $18,000 in benefits	Fully exempt; $0 state tax on Social Security
You claim the subtraction on Schedule M1M	Entire federally taxable portion subtracted

Scenario B — Middle-income married couple near the line

Your situation	Minnesota result
Married joint, AGI $120,000, $32,000 in benefits	Partial tax; subtraction reduced about 30 percent
You take a large IRA withdrawal late in the year	Pushes AGI up and shrinks the subtraction further

Scenario C — High-income retiree

Your situation	Minnesota result
Single, AGI $130,000, $30,000 in benefits	All federally taxable benefits taxed by Minnesota
Subtraction is fully phased out above $120,490	No state relief; plan around the federal senior deduction

The New Federal Senior Deduction (OBBBA) — and Whether Minnesota Follows

A major 2025 change confuses many retirees, so separate it cleanly: this is a federal deduction, not a Minnesota one. The One Big Beautiful Bill Act created a new senior deduction starting in tax year 2025, as explained by Thomson Reuters.

Here is what the federal senior deduction does, point by point:

Amount: Up to $6,000 per person age 65+, or up to $12,000 for a married couple where both qualify.
Effective and sunset years: It applies to tax years 2025 through 2028 only, per the Bipartisan Policy Center — it disappears after 2028 unless Congress extends it.
Phase-out: It shrinks by 6 percent of modified AGI above $75,000 (single) or $150,000 (married joint), and is fully gone at $175,000 (single) or $250,000 (joint).
Eligibility: You must be 65 by December 31, married couples must file jointly, and married-filing-separately seniors are excluded, per STW’s OBBBA summary.
What it is not: It does not exempt Social Security from federal tax — it is a separate below-the-line deduction that reduces federal taxable income.

The misconception worth killing is the claim that the 2025 law “ended taxes on Social Security.” It did not — it added a temporary deduction that helps many seniors but leaves benefits taxable for higher earners.

Does Minnesota conform to the federal senior deduction?

This is the question most state articles get wrong. The federal senior deduction is a below-the-line deduction — it reduces federal taxable income but does not reduce federal AGI, as STW notes. Minnesota’s Social Security subtraction is keyed to federal AGI, so the federal senior deduction does not change the AGI figure that decides your Minnesota threshold.

The practical consequence: the federal $6,000/$12,000 deduction lowers your IRS bill but does not, by itself, expand your Minnesota Social Security subtraction. Minnesota keeps its own separate, generous subtraction with its own thresholds. To know your true 2025 tax picture, you must run the federal senior deduction and the Minnesota subtraction as two distinct calculations.

How to Claim the Minnesota Subtraction (Form Walkthrough)

The Minnesota Social Security Benefit Subtraction is claimed on Schedule M1M, the addition-and-subtraction schedule that attaches to your Form M1 individual return. You compute the subtraction, carry it to M1M, and the total subtractions flow to your M1, lowering your Minnesota taxable income.

Most filers use the simplified method. Under it, you start with your federally taxable Social Security, apply the 100 percent subtraction if you are under the threshold, or reduce the subtraction by 10 percent per $4,000 increment over the threshold. Keep your SSA-1099 and your federal return, because the Minnesota worksheet pulls directly from the federal taxable-benefit figure.

A note on the old “alternative subtraction”: Minnesota still technically allows a hold-harmless method based on pre-2023 rules, but House Research confirms it benefits no taxpayers by 2025 because its parameters were never indexed to inflation. So in practice, use the simplified method.

Deadlines, cost, and timing

The Minnesota individual return is due April 15, 2026 for tax year 2025, the same as the federal deadline, per the Instead deadline guide. Missing it triggers late-filing and late-payment penalties plus interest on any balance owed. If you are due a refund, you simply delay your own money, but penalties bite only when you owe.

Cost-wise, claiming the subtraction is free if you do it yourself in tax software, which handles M1M automatically. A simple paid return runs roughly $200 to $500; a CPA makes sense if you have large withdrawals, a Roth conversion, or income hovering at the threshold where a single decision swings hundreds of dollars.

Mistakes to Avoid

Each of these errors costs Minnesota retirees real money. Watch for them before you file.

Assuming Minnesota fully exempts Social Security like its neighbor Wisconsin does — it does not, and the wrong assumption leads to under-withholding and a surprise bill.
Forgetting to claim the subtraction on Schedule M1M, which leaves your full federally taxable benefit exposed to state tax you did not owe.
Confusing the federal senior deduction with the Minnesota subtraction, and assuming one covers the other — they are separate, and you may qualify for both.
Triggering a large Roth conversion or capital gain near year-end, which spikes your AGI over the threshold and shrinks the subtraction for the whole year.
Using gross benefits instead of federally taxable benefits in the calculation, which produces a wrong subtraction and a flagged return.
Filing married separately without realizing your threshold drops to just $54,160, sharply increasing taxable benefits versus filing jointly.
Ignoring the inflation adjustment and reusing last year’s thresholds, which can put you on the wrong side of the line.

Do’s and Don’ts

These quick rules keep your Minnesota Social Security tax as low as the law allows.

Do:

Do project your December 31 AGI before year-end, because the threshold is the single factor that decides your subtraction.
Do keep your SSA-1099 and federal return together, since the Minnesota worksheet pulls the federally taxable benefit directly from them.
Do consider spreading withdrawals across tax years when you sit near the phase-out line, to preserve a full subtraction.
Do run both the federal senior deduction and the Minnesota subtraction, because each lowers a different tax and missing one overpays.
Do file by April 15, 2026, to avoid penalties and interest on any Minnesota balance due.

Don’t:

Don’t assume your benefits are tax-free just because most Minnesotans pay nothing — confirm against your filing-status threshold.
Don’t file separately to save tax without checking, because the $54,160 separate threshold usually makes things worse.
Don’t rely on a single online “average” instead of your own AGI, since one large withdrawal changes everything.
Don’t skip Schedule M1M, because the subtraction is not automatic on a paper return.
Don’t ignore estimated taxes if you have big non-benefit income, or you may owe a Minnesota underpayment penalty.

Pros and Cons of Minnesota’s Approach

Minnesota’s income-tested subtraction has clear trade-offs compared with a flat exemption.

Pros:

Most retirees pay nothing, because roughly 7 in 10 returns with benefits owe no Minnesota tax on them in 2025.
Targeted relief focuses the exemption on lower- and middle-income filers who need it most.
Inflation indexing raises the thresholds each year, so the exemption keeps pace automatically.
100 percent subtraction below the line means a true zero-tax outcome for qualifying filers, not a partial break.
Predictable mechanics make it possible to plan withdrawals around the threshold.

Cons:

Higher-income retirees pay full freight, with benefits taxed up to the 9.85 percent top rate once fully phased out.
The phase-out is steep, creating a “zig-zag” where small income increases cause outsized tax jumps.
It is more complex than a flat exemption and requires the M1M worksheet.
No conformity with the new federal senior deduction, so the federal break does not lift the state threshold.
Married-separate filers are penalized with a much lower threshold.

Minnesota vs. Neighboring and No-Tax States

Where you live changes the answer entirely. Minnesota is one of only nine states that still tax any Social Security, while 32 states plus D.C. fully exempt it, per House Research.

State	How it treats Social Security (2025)
Minnesota	Taxes benefits above income thresholds; income-tested subtraction exempts most retirees
South Dakota	No state income tax at all, so Social Security is never taxed
Wisconsin	Has an income tax but fully exempts Social Security benefits
Iowa	Fully exempts Social Security from state income tax
North Dakota	Taxes benefits but allows the federal exclusion plus added preferences

The consequence for relocation is concrete. A high-income retiree in Edina paying ~$3,300 of Minnesota tax on benefits would pay $0 by moving to South Dakota or even neighboring Wisconsin — but the move only pays off if total tax, cost of living, and lifestyle all line up. For most middle-income retirees who already owe nothing in Minnesota, relocating purely for the Social Security tax saves little.

What To Do Next

Take these steps in order before you file your 2025 Minnesota return.

Pull your SSA-1099 and your draft federal return to find your federally taxable Social Security amount.
Compare your federal AGI to your filing-status threshold ($108,320 joint, $84,490 single/HOH for 2025).
Complete the Social Security subtraction on Schedule M1M using the simplified method.
Check whether you qualify for the federal senior deduction of up to $6,000/$12,000 if you are 65 or older.
File and pay by April 15, 2026 to avoid penalties.
Call a CPA if you have a Roth conversion, large capital gain, or income near the threshold, where one decision swings hundreds of dollars.

FAQs

Does Minnesota tax Social Security benefits?

Sometimes. For tax year 2025, benefits are fully exempt below $108,320 AGI (married joint) or $84,490 (single/HOH). Above those lines, part of your federally taxable benefits becomes subject to Minnesota tax.

At what income does Minnesota start taxing Social Security in 2025?

$108,320 for married joint filers and $84,490 for single or head of household. Below those AGI figures your benefits are fully exempt; above them, the subtraction begins to phase out.

Is all of my Social Security taxed once I cross the threshold?

No. Only the portion already taxable federally can be taxed by Minnesota, and even that phases in gradually — losing 10 percent of the subtraction per $4,000 of AGI over the threshold.

Do most Minnesota retirees pay state tax on Social Security?

No. About 29 percent of returns with benefits pay any Minnesota tax on them in 2025, meaning roughly 70 percent pay nothing, per Minnesota House Research modeling.

Did the 2025 federal law end taxes on Social Security?

No. The OBBBA added a temporary senior deduction of up to $6,000 per person for 2025 through 2028, but Social Security remains taxable, especially for higher earners.

Does Minnesota follow the new federal senior deduction?

No, not for its subtraction. The federal deduction lowers federal taxable income but not federal AGI, and Minnesota’s Social Security threshold is based on AGI, so it is unaffected.

Which form do I use to claim the Minnesota subtraction?

Schedule M1M, attached to Form M1. You compute the subtraction with the simplified method and carry it to M1M, which reduces your Minnesota taxable income.

What is the Minnesota tax rate on taxable benefits?

5.35 percent to 9.85 percent. Taxable Social Security is taxed at your ordinary Minnesota marginal rate, so high earners can pay the top 9.85 percent rate on the taxed portion.

Does a Roth conversion affect my Minnesota Social Security tax?

Yes. A conversion raises your federal AGI, which can push you over the threshold and shrink your subtraction for that year, increasing the benefits Minnesota taxes.

When is my 2025 Minnesota return due?

April 15, 2026. Filing or paying late triggers penalties and interest on any Minnesota balance owed.

Is married filing separately a good way to lower this tax?

Usually no. The separate threshold drops to just $54,160 for 2025, which typically makes more of your benefits taxable than filing jointly would.

Does Minnesota tax other retirement income too?

Yes. Pensions, 401(k) and IRA withdrawals, and most other retirement income are taxable in Minnesota, unlike Social Security, which has its own income-tested subtraction.
