Wisconsin Taxes on Pensions IRAs and 401ks

Wisconsin Taxes on Pensions IRAs and 401ks – Wisconsin follows federal rules for most retirement income but offers key exemptions, subtractions, and deductions that can significantly reduce or eliminate state taxes on pensions, IRAs, and 401(k) distributions. This is especially true for seniors thanks to a major expansion of the retirement income subtraction starting in tax year 2025.

If you’re a Wisconsin resident or planning retirement in the state, understanding these rules helps optimize your tax strategy. Below is a clear, up-to-date breakdown based on official Wisconsin Department of Revenue (DOR) guidance for the 2025 tax year.

Overview of Wisconsin Retirement Income Taxation

Wisconsin taxes retirement benefits received by full-year residents in largely the same way as the federal government. Any pension, annuity, IRA distribution, or 401(k) withdrawal that is taxable on your federal return is generally taxable on your Wisconsin return—even if the income comes from services performed in another state.

However, Wisconsin provides several important breaks:

Full exemption for Social Security and Railroad Retirement benefits.
Specific exemptions for certain pre-1964 public pensions and military benefits.
A generous new retirement income subtraction (up to $24,000 single / $48,000 joint).
An extra $250 personal exemption for those age 65 and older.

Nonresidents and part-year residents face different rules, often more favorable for qualified plan distributions.

Are Pensions Taxed in Wisconsin?

Yes, most pensions are taxable in Wisconsin if they are taxable federally. This includes private employer pensions, annuities, and distributions from qualified employee plans.

Key exemptions include:

U.S. military retirement pay (paid by the Defense Finance and Accounting Service).
Certain federal uniformed services (Coast Guard, NOAA, Public Health Service).
Benefits from the Wisconsin State Teachers Retirement System, specific Milwaukee city/county systems, or federal Civil Service Retirement System—if you (or the deceased) were a member as of December 31, 1963, and meet specific account conditions. These may be fully or partially exempt using a proration formula.

Lump-sum distributions reported on federal Form 4972 are taxable in Wisconsin as ordinary income.

How Are IRAs Taxed in Wisconsin?

Traditional IRA distributions that are taxable on your federal return are also taxable in Wisconsin. This includes regular withdrawals, required minimum distributions (RMDs), and most inherited IRA payments (if the recipient meets eligibility rules).

Roth IRA qualified distributions remain completely tax-free in Wisconsin, just as they are federally.

A special rule applies to IRAs invested in U.S. government securities: A portion of the distribution may be exempt to the extent it is attributable to U.S. government interest.

Wisconsin 401(k) and Other Retirement Plan Taxes

Distributions from 401(k), 403(b), 457 plans, SEP IRAs, and similar qualified retirement plans follow the same rules as pensions and traditional IRAs:

Taxable federally → taxable in Wisconsin for residents.
Qualified plan distributions are not taxable to nonresidents, even if earned while working in Wisconsin.

Nonqualified plans (those that don’t meet IRC requirements) are taxable to Wisconsin residents and, in some cases, to nonresidents if the income is attributable to Wisconsin services—unless paid as a life annuity or under specific “mirror plan” rules.

New 2025 Retirement Income Subtraction: Up to $24,000 (or $48,000 Joint) Tax-Free

Wisconsin dramatically expanded its retirement income subtraction for 2025 and beyond. This is one of the most retiree-friendly changes in the state’s tax code.

Eligibility and amounts:

Age 67 or older (by Dec. 31 of the tax year): Subtract up to $24,000 of qualifying retirement income (single filers or head of household). Married filing jointly can subtract up to $48,000 if both spouses are 67 or older.
No federal adjusted gross income (FAGI) limit applies to this subtraction.
You cannot claim any Wisconsin income tax credits (including carryforwards) in the same year you claim this subtraction.

Qualifying income includes taxable distributions from qualified retirement plans or IRAs (including inherited IRAs if the recipient meets the age requirement). It does not apply to already-exempt income like military pensions or Social Security.

Alternative subtraction (age 65+ with low income): Up to $5,000 ($10,000 joint if both qualify) if FAGI is under $15,000 single / $30,000 married. Most retirees will use the larger 67+ subtraction instead.

Part-year residents prorate the subtraction based on Wisconsin AGI.

Additional Deductions and Credits for Wisconsin Seniors

Extra personal exemption: $250 per person age 65 or older on Dec. 31, 2025.
Medical and long-term care insurance subtractions: Premiums for qualifying policies (not paid with pre-tax retirement funds).
Homestead Credit: Available to residents age 62+ (or disabled) with household income under $24,680 (2025 limit).
Medical expense deduction: Wisconsin allows this even if you don’t itemize federally (subject to 7.5% AGI floor).

Wisconsin State Income Tax Rates for 2025

Wisconsin uses a graduated income tax with four brackets (after subtractions, deductions, and exemptions):

Single / Head of Household:

$0 – $14,680: 3.50%
$14,680 – $50,480: $513.80 + 4.40% of excess
$50,480 – $323,290: $2,089 + 5.30% of excess
Over $323,290: $16,547.93 + 7.65% of excess

Married Filing Jointly:

$0 – $19,580: 3.50%
$19,580 – $67,300: $685.30 + 4.40% of excess
$67,300 – $431,060: $2,784.98 + 5.30% of excess
Over $431,060: $22,064.26 + 7.65% of excess

Married Filing Separately: Half the joint brackets.

Filing is required if your gross income exceeds age-adjusted thresholds (e.g., $14,510+ for single age 65+).

These are completely exempt from Wisconsin income tax, regardless of how much is taxable federally. No subtraction is needed—they are simply not included in Wisconsin taxable income.

Tax Rules for Nonresidents and Part-Year Residents

Qualified plans (401(k), IRAs, etc.): Generally not taxable in Wisconsin if you are a nonresident when you receive the payments.
Nonqualified plans: May be taxable if tied to Wisconsin service, unless paid as a qualifying annuity or lump sum under mirror-plan rules.
Part-year residents are taxed only on income received while a Wisconsin resident (with prorated subtractions).

This makes Wisconsin attractive for retirees who move out of state after working here.

How to Report and Minimize Wisconsin Taxes on Retirement Income?

Report differences on Schedule SB (residents) or Schedule M (nonresidents/part-year). Use Wisconsin Publication 126 for detailed worksheets and examples.

Practical tips:

Maximize the $24,000/$48,000 subtraction by strategically timing distributions.
Consider Roth conversions before age 67 if it fits your overall plan.
Request voluntary state withholding or make estimated payments (Form 1-ES) to avoid underpayment penalties.
Consult Publication 106 (Wisconsin Tax Information for Retirees) and Publication 126 (How Your Retirement Benefits Are Taxed) directly from revenue.wi.gov.

Final Thoughts: Is Wisconsin Retirement Tax-Friendly?

With the 2025 expansion of the retirement income subtraction, Wisconsin has become significantly more attractive for retirees. Many seniors can now exclude tens of thousands of dollars in pension, IRA, and 401(k) income from state tax—combined with full Social Security exemption and no estate tax.

Tax rules can be complex and depend on your specific situation, age, filing status, and residency. Always verify the latest forms and instructions on the Wisconsin DOR website or consult a tax professional. Laws can change, but as of the 2025 tax year, these are the current rules from official DOR publications.
