Wisconsin Retirement Income Tax Guide 2026

Wisconsin's tax treatment of retirement income is a mix of generous and ordinary: Social Security benefits are completely off the table for state tax purposes, no matter how much you receive or how much other income you have. But pensions, 401(k) distributions, and IRA withdrawals don't get the same blanket pass — Wisconsin generally taxes them exactly as the IRS does, folding them into ordinary income and running them through the state's four-bracket progressive rate schedule (3.5% to 7.65% for 2026). That puts Wisconsin in a different category from neighbors like Illinois, which exempts essentially all retirement income with no cap.

What changed for 2026 is a new age-based subtraction: starting with the 2025 tax year, Wisconsin residents 67 and older can subtract up to $24,000 (or $48,000 on a joint return) of qualifying retirement income from their state taxable income — with no income limit attached. There's also an older, much narrower $5,000 subtraction for retirees 65 and up who fall under specific income thresholds, plus a handful of legacy exemptions for military pensions and a small number of pre-1964 government retirement accounts. This guide walks through exactly how each piece works, Wisconsin's 2026 brackets and unusual sliding-scale standard deduction, and how the total tax bill compares to Illinois and Minnesota.

Does Wisconsin Tax Social Security Benefits?

No. Wisconsin Department of Revenue Publication 126 states it plainly: "Social security benefits are not taxable by Wisconsin." This is a complete exemption — it applies at every income level, with no phase-out and no age requirement, even though up to 85% of those same benefits can be taxable on your federal return.

This exemption also extends to the Social Security-equivalent portion of railroad retirement benefits (Tier 1 benefits from the U.S. Railroad Retirement Board). Federal law separately bars states from taxing railroad retirement income entirely, so railroad retirees get a full pass on both Tier 1 and Tier 2 benefits regardless of how those amounts are characterized federally.

What Is Wisconsin's New $24,000/$48,000 Retirement Income Subtraction for Filers 67 and Older?

Starting with the 2025 tax year — and continuing for 2026 — Wisconsin residents who are at least 67 years old before the close of the tax year can subtract up to $24,000 of "qualifying retirement income" (taxable distributions from a qualified retirement plan or an IRA) from their state taxable income. On a joint return where both spouses are 67 or older, the couple can subtract up to $48,000 combined, regardless of which spouse actually received the income.

Unlike many other states' retirement exclusions, this one has no income cap — a retiree with $300,000 in total income can claim the full $24,000/$48,000 subtraction just like a retiree with $40,000 in income. Part-year Wisconsin residents must prorate the subtraction based on the ratio of Wisconsin income to federal adjusted gross income; nonresidents cannot claim it at all.

There is one important trade-off to know before claiming this subtraction: taxpayers who use it cannot claim any Wisconsin tax credit (via Schedule CR or directly on Form 1/1NPR) for that tax year — including forfeiting any credit carried forward from a prior year. For most retirees whose main state-level credits are modest, the $24,000/$48,000 subtraction is still the better deal, but anyone with a significant homestead credit or other carryforward should run the comparison both ways.

Is There Also an Older $5,000 Subtraction for Retirees Age 65 and Older?

Yes — separately from the new 67+ subtraction, Wisconsin has long offered a smaller, income-limited subtraction for retirees 65 and older. To qualify, you must be at least 65 before the close of the tax year, and your federal adjusted gross income must be:

• Under $15,000 if single or head of household
• Under $30,000 combined if married filing jointly
• Under $30,000 combined (both spouses' income added together) if married filing separately

Eligible taxpayers can subtract up to $5,000 of qualifying retirement income. Because the subtraction applies separately to each spouse, a married couple where both spouses are 65+ and both have qualifying retirement income can subtract up to $10,000 combined on a joint return — provided the couple's combined federal AGI stays under the $30,000 threshold.

Given how low that income ceiling is, this older subtraction mainly helps Wisconsin retirees living on modest fixed incomes. Anyone 67 or older with income above these thresholds will generally rely on the larger, uncapped $24,000/$48,000 subtraction described above instead.

How Does Wisconsin Tax Pensions, 401(k)s, and IRA Withdrawals?

Outside of the subtractions above, Wisconsin's default rule (per Publication 126) is simple: whatever amount of your retirement benefit is taxable on your federal return is also taxable on your Wisconsin return. There is no blanket state exclusion for private pensions, 401(k) distributions, or traditional/Roth IRA withdrawals the way there is in Illinois or Pennsylvania. Once federally taxable retirement income exceeds whatever you can subtract under the 67+ or 65+ provisions, the remainder is taxed as ordinary income at Wisconsin's progressive rates.

There are a handful of narrower exemptions worth knowing about:

The pre-1964 government-account exemption is a real provision still on the books, but it's effectively a legacy rule: it only applies to specific Milwaukee-area municipal systems, the Wisconsin State Teachers Retirement System, and federal CSRS accounts, and only where the underlying account was established more than six decades ago. Because of the account-establishment-date requirement, it does not apply to WRS (Wisconsin Retirement System) accounts opened after 1963, even if you're combining pre-1964 service credit with a later-established account. Very few current retirees qualify, though some legacy beneficiaries still do — if this might apply to you, verify directly against Publication 126's worked examples or with the Wisconsin DOR before assuming eligibility.

What Are Wisconsin's 2026 Income Tax Brackets and Standard Deduction?

Wisconsin uses four progressive brackets for 2026, per the Wisconsin DOR's official 2026 tax rate schedules:

Wisconsin's standard deduction is unusual: rather than a flat amount, it's a sliding scale that starts at a maximum and shrinks as income rises, eventually hitting zero. For 2026:

• Single filers: $13,960 flat if Wisconsin income is $20,119 or below; from there it's reduced by 12% of income above $20,120, reaching $0 once income hits $136,453.
• Married filing jointly: $25,840 flat if income is $29,039 or below; reduced by 19.778% of income above $29,040, reaching $0 at $159,690.
• Head of household: $18,030 flat up to $20,119, then a steeper 22.515% reduction phase before converging with the single schedule.

On top of the standard deduction, Wisconsin allows a personal exemption of $700 per person (yourself, your spouse if filing jointly, and each dependent), plus an additional $250 if you (and/or your spouse, on a joint return) are 65 or older by year-end. Because the standard deduction shrinks as income rises, a retiree with $150,000+ in taxable retirement income effectively gets little or no standard deduction at all — a detail that matters more for higher-income Wisconsin retirees than it does in most other states.

Worked Examples: How Much Would a Wisconsin Retiree Actually Owe?

These are simplified, illustrative single-filer examples using the 2026 brackets, sliding-scale standard deduction, and exemption amounts above. They assume all non-Social Security income is "qualifying retirement income" eligible for the applicable subtraction. Your actual liability depends on your full income picture — use the Retirement Income Tax by State Calculator for a number tailored to your situation.

Note that Social Security is excluded from all three scenarios' taxable totals since it's never taxed by Wisconsin. The gap between the second and third scenarios shows the real dollar value of the age-67+ subtraction: despite having $20,000 more in retirement income, the 70-year-old in scenario three owes roughly $250 less state tax than the 60-year-old in scenario two, purely because of the $24,000 subtraction plus the additional $250 exemption for being 65+.

How Does Wisconsin Compare to Illinois and Minnesota for Retirees?

Wisconsin sits in the middle of its regional neighbors when it comes to retirement income tax:

Illinois remains the clear winner for retirees with large pensions or IRA balances — its exemption has no dollar cap at all. Wisconsin is a step down from Illinois but is meaningfully better than Minnesota on two fronts: Wisconsin never taxes Social Security regardless of income, while Minnesota's exemption phases out for higher-income retirees, and Wisconsin's new age-67+ subtraction shelters a real chunk of pension/IRA income that Minnesota doesn't shelter at all. Wisconsin's 7.65% top rate is also noticeably lower than Minnesota's 9.85% top rate, which matters for retirees drawing down large IRA or 401(k) balances in high-income years (such as when taking required minimum distributions).
