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

Quick Answer

No. Wisconsin does not tax Social Security benefits. For tax year 2025 (the 2026 filing season), every dollar of your Social Security retirement, survivor, or disability benefit is fully exempt from Wisconsin income tax — at any age and at any income level — even when part of that benefit is taxed on your federal return.

This article reflects federal rules and Wisconsin rules as of June 2026 and covers tax year 2025. Tax law changes — confirm current figures with the Wisconsin Department of Revenue before you file.

If you live in Wisconsin and depend on Social Security, the state takes none of it. That matters because Social Security is the single largest income source for most retirees, and a state tax bite on it would shrink the check that pays your rent, your groceries, and your prescriptions. Wisconsin spares you that bite entirely — a fact confirmed in plain language by the Wisconsin Department of Revenue, which states flatly that “Wisconsin does not tax social security benefits.”

The timing is good, too. Starting in tax year 2025, Wisconsin also created a brand-new subtraction of up to $24,000 ($48,000 for couples) for other retirement income for filers 67 and older, signed into law as part of 2025 Wisconsin Act 15. According to the Social Security Administration data cited by industry sources, Social Security is a source of retirement income for about 91% of current retirees — so this exemption touches almost everyone who retires in the state.

The Short Version: Wisconsin and Social Security

Wisconsin is one of the large majority of states that fully exempt Social Security from state income tax. The state’s income tax code starts from your federal adjusted gross income, then lets you subtract the taxable portion of Social Security back out, so it never gets taxed at the Wisconsin level. The Wisconsin Department of Revenue’s retiree FAQ confirms this directly: “Social security benefits are not taxable by Wisconsin.”

This is not a deduction you have to fight for or phase out of. There is no age requirement, no income cap, and no dollar limit on the Social Security exemption. A 62-year-old taking early benefits and a 90-year-old widow both get the same treatment: full exemption. As SmartAsset notes, Wisconsin does not tax Social Security retirement benefits “even those taxed at the federal level.”

The exemption also covers Railroad Retirement benefits, which the Wisconsin DOR lists as “not taxable for Wisconsin income tax purposes.” So whether your benefit comes from the Social Security Administration or the Railroad Retirement Board, Wisconsin leaves it alone. The why is simple policy: Wisconsin has long chosen to protect basic retirement security income from state tax, and lawmakers have repeatedly declined to change that, as noted by the Badger Institute, which points out “Social Security already is exempt from income taxes in Wisconsin.”

The consequence for you is real money. If you collect $30,000 a year in Social Security, Wisconsin taxes $0 of it, while a retiree across the border in Minnesota might owe state tax on part of the same benefit. The next step is simple: make sure the taxable amount from your federal return is correctly subtracted on your Wisconsin return — which we walk through below.

Federal vs. Wisconsin: Why the Two Answers Differ

The most common confusion is this: your federal return may tax part of your Social Security, but your Wisconsin return does not. These are two separate governments with two separate rulebooks, and one does not follow the other here. Understanding both keeps you from overpaying — or from being surprised by a federal bill.

How the Federal Government Taxes Social Security

The IRS uses a formula based on “provisional income” — your adjusted gross income, plus tax-exempt interest, plus half of your Social Security benefits. If that total crosses certain thresholds, up to 50% or even 85% of your benefits become federally taxable. For a single filer, taxation can begin once provisional income passes $25,000, and the 85% tier kicks in above $34,000, per the long-standing thresholds explained by the Social Security Administration.

These federal thresholds have not been adjusted for inflation in decades, so more retirees cross them every year. The consequence is that a middle-income retiree often pays federal tax on 85% of their benefits while paying nothing at the state level in Wisconsin. The next step is to confirm your taxable amount on your federal Form 1040, line 6b — that number is the starting point for your Wisconsin subtraction.

How Wisconsin Treats the Same Dollars

Wisconsin begins your state return with federal adjusted gross income, which already includes that taxable 6b amount. The state then lets you subtract it back out on your Wisconsin return, zeroing out the tax on Social Security. The AARP Wisconsin tax guide puts it plainly: “Social Security income is exempt from income tax in Wisconsin.”

The common misconception is that because the IRS taxed part of your benefit, Wisconsin must too. It does not. The consequence of believing the myth is overpaying — some retirees mistakenly add the federal taxable amount to their Wisconsin income and never subtract it. The next step: claim the subtraction on Schedule SB (or Schedule M for part-year and nonresident filers) so the exempt amount is removed.

The New 2025 Retirement Income Subtraction

Social Security is already tax-free in Wisconsin, but starting in tax year 2025 the state added a powerful new break for your other retirement income — 401(k) withdrawals, IRA distributions, and most private pensions. Created by 2025 Wisconsin Act 15, this subtraction can shield a large chunk of taxable retirement income that used to be fully taxed.

The headline numbers are big. Filers who are at least 67 years old at the close of the tax year may subtract up to $24,000 of retirement income, or up to $48,000 on a joint return when both spouses qualify, according to the Wisconsin Department of Revenue. The Milwaukee Journal Sentinel reports retirees “can now subtract $24,000 in retirement income on their state forms, or double that amount for joint filers.”

There is an older, smaller subtraction too. Filers at least 65 may subtract up to $5,000 of retirement income, but only if federal adjusted gross income is under $15,000 ($30,000 combined for married filers), per the Wisconsin DOR. Most retirees with meaningful income will not qualify for the $5,000 version and should look to the $24,000/$48,000 subtraction instead.

The catch is the most important detail in this whole article: if you claim the new $24,000/$48,000 subtraction, you may not claim any credit on your return for that tax year, as stated directly by the Wisconsin DOR. That means you give up the homestead credit, the school property tax credit, and other credits for that year. The next step is to run the math both ways — sometimes the credits you lose are worth more than the subtraction you gain.

What Counts and What Does Not

The subtraction applies to taxable retirement income — think traditional IRA and 401(k) withdrawals and private pensions. It does not apply to income that is already exempt, so you cannot “double dip” by claiming Social Security, military retirement, or qualifying federal pensions under this subtraction, per the Wisconsin DOR. The consequence of trying is a corrected return and a smaller refund. The next step is to map each income source to the right line before you file.

Which Situation Applies to You?

Wisconsin’s answer on Social Security is always “not taxed,” but your total retirement tax picture depends on your facts. Use this guide to find the part that fits you.

You live only on Social Security. Your Wisconsin income tax is likely $0 from those benefits. You may still file to claim the homestead credit if your household income is under the limit. Skip to “What to Do Next.”
You have Social Security plus a pension or 401(k), and you are 67+. Social Security is exempt, and you may subtract up to $24,000 ($48,000 joint) of the other income — but weigh the lost credits. See “The New 2025 Retirement Income Subtraction.”
You are a military or federal civil-service retiree. Your Social Security is exempt, and your qualifying military or pre-1964 federal pension is also exempt — separate from the $24,000 rule.
You moved into or out of Wisconsin this year. You are a part-year resident; only income earned while a Wisconsin resident is taxed, and you file on Form 1NPR with Schedule M.
You are a higher-income retiree. Wisconsin still exempts 100% of your Social Security, even though the IRS likely taxes 85% of it federally.

Worked Example: The Real Dollars You Save

Numbers make this concrete. Below is a fully worked example you can copy with your own figures. It compares a Wisconsin retiree to an identical retiree in Minnesota, which still partially taxes Social Security.

The setup: Margaret is a single 70-year-old. She receives $30,000 in Social Security and withdraws $20,000 from her traditional IRA, for $50,000 total. On her federal return, 85% of her Social Security — $25,500 — is taxable.

Step 1 — Federal taxable Social Security: $30,000 × 85% = $25,500 lands on federal Form 1040, line 6b.

Step 2 — Wisconsin starting income: Wisconsin starts from her federal AGI, which includes the $25,500 plus her $20,000 IRA = $45,500 of federally taxable income from these sources.

Step 3 — Subtract Social Security in Wisconsin: Wisconsin removes the entire $25,500 of taxable Social Security. Remaining: $20,000 of IRA income.

Step 4 — Apply the 2025 senior subtraction: Because Margaret is over 67, she subtracts up to $24,000 of the IRA income. Her $20,000 IRA withdrawal is fully covered. Remaining Wisconsin taxable retirement income: $0.

Step 5 — The result: Margaret owes $0 Wisconsin income tax on this income. At Wisconsin’s bottom 3.5% rate, taxing even the $20,000 IRA alone would have cost about $700 before the subtraction, and taxing Social Security on top would have added more.

By contrast, a Minnesota retiree with the same income could owe state tax on part of her Social Security, because Minnesota only offers a partial Social Security subtraction. The lesson: Wisconsin’s full exemption plus the new subtraction can drive a typical retiree’s state tax on retirement income to zero.

Three Common Scenarios

Below are the three most common situations Wisconsin retirees face, each shown as a quick situation-and-result table.

Scenario 1 — Social Security Only

Your Situation	What Wisconsin Does
Single retiree, $22,000 in Social Security, no other income	Taxes $0; benefit is fully exempt, no filing tax owed
Wonders if filing is even required	May file anyway to claim homestead credit if income is under $24,680

Scenario 2 — Social Security Plus a Pension (Age 67+)

Your Situation	What Wisconsin Does
Married couple, both 68, $40,000 Social Security + $40,000 pension	Exempts all Social Security; subtracts up to $48,000 of the pension
Also wants the homestead credit	Cannot take both — claiming the subtraction blocks all credits that year

Scenario 3 — Higher-Income Retiree

Your Situation	What Wisconsin Does
Single, 64, $35,000 Social Security + $90,000 investment and IRA income	Exempts 100% of Social Security even though the IRS taxes 85%
Too young for the $24,000 subtraction (must be 67)	Taxes the IRA income normally; Social Security stays fully exempt

Named Examples

Carlos, age 66, Green Bay. Carlos collects $28,000 in Social Security and takes $15,000 from his 401(k). Wisconsin exempts his Social Security entirely. But Carlos is 66 — one year shy of the 67 cutoff — so he cannot yet claim the $24,000 subtraction on the 401(k). His lesson: waiting one year to take larger withdrawals could shelter them.

Dorothy, age 72, widow, Madison. Dorothy receives $26,000 in Social Security and a $30,000 private pension. Wisconsin exempts the Social Security, and she subtracts $24,000 of the pension, leaving only $6,000 taxable. She skips the homestead credit because the subtraction is worth more to her than the credit she would lose.

The Nguyens, both 69, Milwaukee. They have $44,000 in combined Social Security and $50,000 in IRA withdrawals. Social Security is fully exempt, and they subtract $48,000 of the IRA, leaving $2,000 taxable. They run the numbers and confirm the lost credits are minor compared to the subtraction’s value.

Wisconsin vs. Neighboring States

How does Wisconsin stack up regionally? The table below compares Social Security treatment across three Midwest neighbors for tax year 2025.

State	How It Treats Social Security
Wisconsin	Fully exempt — no age or income limit, per WI DOR
Minnesota	Partially taxable; a subtraction phases out by income
Illinois	Fully exempt; Illinois does not tax most retirement income at all

The takeaway is that Wisconsin and Illinois both fully protect Social Security, while Minnesota can still tax part of it for middle- and upper-income retirees. Wisconsin’s edge over Illinois, though, is the new 2025 subtraction on other retirement income — a break Illinois retirees do not need because Illinois already exempts that income. The next step if you are choosing where to retire is to weigh property and sales taxes too, since Wisconsin’s property taxes run high, averaging about 1.73%.

Mistakes to Avoid

Adding Social Security to Wisconsin income. If you forget the subtraction, you overpay state tax on income Wisconsin never meant to tax — sometimes hundreds of dollars.
Claiming the $24,000 subtraction and a credit. Doing both triggers a corrected return; the DOR rule bars all credits in any year you take the subtraction.
Claiming the subtraction before age 67. You must be 67 by the close of the tax year; claiming at 66 means a denied subtraction and a recalculated bill.
Double-dipping on exempt income. Trying to subtract military pay or Social Security under the $24,000 rule is disallowed, leading to an adjustment.
Ignoring estimated taxes on IRA income. If Wisconsin tax is not withheld and you will owe $500 or more, you may face an underpayment charge, per the WI DOR.
Assuming federal rules carry to the state. Believing the IRS taxing 85% means Wisconsin taxes it too causes needless overpayment.
Skipping the homestead credit when eligible. Low-income retirees who could claim it leave money on the table by not filing.

Do’s and Don’ts

Do subtract your federally taxable Social Security on your Wisconsin return — because that is what makes it tax-free at the state level.
Do confirm you are 67+ before claiming the $24,000/$48,000 subtraction, because age is the hard gate.
Do run the math both ways, since the credits you lose may outweigh the subtraction.
Do keep your 1099-R and SSA-1099 forms, because they document the income and the exemption.
Do check estimated-tax rules if you take large IRA withdrawals, to avoid an underpayment charge.
Don’t report Social Security as Wisconsin taxable income, because the state exempts every dollar.
Don’t stack the subtraction with credits in the same year, because the law forbids it.
Don’t assume military or federal pensions need the $24,000 rule, since they are already exempt.
Don’t guess your residency status if you moved, because part-year rules change what is taxed.
Don’t skip filing just because Social Security is exempt, since you may forfeit a refundable credit.

What to Do Next

Follow these steps for the 2026 filing season (tax year 2025):

Gather your forms — SSA-1099 for Social Security and 1099-R for pensions and IRA withdrawals.
Find your federal taxable Social Security on Form 1040, line 6b — this is what you subtract.
Complete Schedule SB (or Schedule M for part-year/nonresident filers) to subtract your Social Security and, if eligible, your retirement income, using the WI DOR instructions.
Check the credit trade-off if you are 67+ before claiming the $24,000/$48,000 subtraction.
File by April 15, 2026 to avoid late penalties, and set up estimated payments if you owe $500 or more.
Call a CPA if you have multiple income types, recently moved, or are weighing the subtraction against credits — the cost of a professional review is small next to a wrong election.
