Wisconsin does not tax most pension income, but the rules depend on when you started receiving it and what type of pension you have

Wisconsin exempts most pension income from state income tax, but the exemption has an age requirement and does not cover all retirement income equally. If you receive a pension from your former employer — whether public sector, military, or private — you generally pay no Wisconsin state tax on it once you turn 65. Income from IRAs, 401(k)s, and other retirement accounts follows different rules and is taxable unless it qualifies for a separate exemption.

The key distinction is between pension payments (regular checks from a pension plan) and retirement account withdrawals (money you take out of an IRA or 401(k)). Wisconsin taxes the second but not the first, with one important exception for those under 65.

Key Takeaways

  • Pension income is exempt from Wisconsin state income tax if you are 65 or older, regardless of the pension source.
  • If you receive a pension before age 65, Wisconsin taxes it as ordinary income unless it qualifies as military retirement pay.
  • Withdrawals from IRAs, 401(k)s, and similar retirement accounts are taxable in Wisconsin and do not receive the pension exemption.
  • Social Security benefits are not taxed by Wisconsin, but they may affect your federal tax situation.

Pension income at age 65 and older

Once you reach 65, Wisconsin excludes all pension income from your state income tax return. This applies to pensions from any source: a private employer, a government agency, a school district, or the military. You still report the income on your Wisconsin tax form, but you subtract it as an exemption, resulting in no state tax owed on that amount.

This exemption covers the full amount of your pension payment, no matter how large. If you receive $3,000 per month from a pension, all $3,000 is exempt. You do not need to file a separate form or request the exemption — you claim it directly on your Wisconsin income tax return (Form 1040-WI or Form 1040-ES-WI, depending on whether you are filing a full return or making estimated payments).

Pension income before age 65

If you receive a pension before turning 65, Wisconsin taxes it as ordinary income at your regular tax rate. This applies to early retirement pensions, disability pensions from private employers, and other pension payments received before your 65th birthday. The only exception is military retirement pay, which is exempt from Wisconsin tax at any age.

Military pensions are treated differently because they are exempt under federal law and Wisconsin honors that exemption. If you are a retired service member receiving military retirement pay before 65, you do not owe Wisconsin state tax on it. All other pension income received before 65 is taxable.

Retirement account withdrawals (IRAs, 401(k)s, and similar accounts)

Money you withdraw from an IRA, 401(k), 403(b), or similar retirement account is taxed by Wisconsin as ordinary income, regardless of your age. These withdrawals do not receive the pension exemption because they are not pension payments — they are distributions from an account you control. This applies whether you take a lump sum, regular withdrawals, or required minimum distributions (RMDs) after age 73.

The only partial exception is for Roth IRA withdrawals. If you withdraw money you originally contributed to a Roth IRA (not the earnings), that portion is not taxed by Wisconsin because it was already taxed when you earned it. Withdrawals of Roth earnings are taxable unless you meet specific conditions (age 59½ and the account has been open at least five years). Consult a tax preparer about your specific Roth situation, as the rules are detailed.

Social Security and other retirement income

Wisconsin does not tax Social Security benefits at the state level. This is true regardless of your age or income level. However, Social Security may still affect your federal tax situation — the federal government taxes Social Security for some higher-income retirees, and Wisconsin's exemption does not change that.

Other income sources common in retirement — such as interest, dividends, rental income, or part-time work — are taxed by Wisconsin at your regular rate. Only pension income (at 65+) and Social Security are exempt. If you have questions about whether a specific income source is taxable, contact the Wisconsin Department of Revenue or a tax preparer.

How to report pension income on your Wisconsin tax return

Report all pension income on your Wisconsin return, even though most of it will be exempt. On Form 1040-WI, pension income goes on line 5b (or the corresponding line for your form year). If you are 65 or older, you then claim the pension exemption on the same form, which reduces your taxable income to zero for that source.

If you receive a pension and other income (such as part-time wages or Social Security), you report each source separately. Only the pension portion is exempt; the other income is taxed normally. Keep your pension statements and any 1099-R forms you receive from your pension provider — you will need them to complete your return accurately.

Federal tax implications of Wisconsin pension exemption

Wisconsin's exemption of pension income does not affect your federal taxes. The federal government taxes most pension income regardless of your age, and Wisconsin's state exemption does not change that. You may owe federal income tax on a pension that is exempt from Wisconsin tax.

If you are 65 or older, you do receive a higher standard deduction on your federal return, which can reduce your federal tax burden. This is a federal benefit, not related to Wisconsin's pension exemption. Consult a tax preparer or the IRS website if you need help understanding your federal tax situation.

Frequently Asked Questions

Do I have to pay Wisconsin tax on my pension if I move out of state?

No. Wisconsin taxes only income earned or received while you are a resident. If you move to another state, you are no longer subject to Wisconsin income tax, even on a pension from a Wisconsin employer. You may owe tax to your new state depending on its rules. Contact your new state's tax authority to learn what applies.

What if I receive both a pension and Social Security?

Both are exempt from Wisconsin tax if you are 65 or older. Report both on your return, claim both exemptions, and your Wisconsin taxable income from these sources will be zero. Other income you receive (wages, interest, dividends) is still taxable.

Is a lump-sum pension payment taxed differently than monthly payments?

No. Whether you receive your pension as a single lump sum or as monthly payments, the same exemption applies if you are 65 or older. The entire amount is exempt. If you are under 65, the entire amount is taxable regardless of how it is paid.

Do I need to file a Wisconsin return if my only income is a pension and I am 65 or older?

You may still need to file if your total income exceeds the filing threshold for your age and filing status, even though the pension itself is exempt. Wisconsin requires you to file if your gross income meets certain minimums. Check the Wisconsin Department of Revenue website or contact them to confirm whether you must file based on your specific situation.
