Wisconsin Taxes on Pensions, IRAs, and 401(k)s

If you’re retired or planning retirement in Wisconsin, understanding how the state taxes different sources of retirement income can help you plan withdrawals and manage your tax bill.

Wisconsin is moderately retirement-friendly in certain areas, but many types of retirement income are still taxable.

You can feel reassured knowing that Social Security benefits are fully exempt from state tax in Wisconsin.

Wisconsin Income Tax Overview

Wisconsin uses a graduated income tax system, meaning higher income levels are taxed at higher rates.

The state starts with your federal Adjusted Gross Income (AGI) and then applies Wisconsin-specific adjustments and subtractions to determine Wisconsin taxable income.

Social Security Benefits

Wisconsin does not tax Social Security benefits.

This includes:

• Social Security retirement benefits

• Social Security disability benefits

• Railroad Retirement Tier 1 benefits

Even if part of your Social Security income is taxable federally, it is fully exempt from Wisconsin state income tax.

Example:
A retiree receiving $28,000 in Social Security benefits owes no Wisconsin state tax on that income.

Pension Income in Wisconsin

Most pension income is taxable in Wisconsin.

Taxable pension income generally includes:

• Employer pensions

• Private employer retirement plans

• Federal civil service pensions

• 401(k) annuity distributions

• Other defined benefit or defined contribution pension payments

However, Wisconsin provides certain exemptions for specific government pensions, depending on the plan and participation dates.

Example:
A retiree receiving $35,000 per year from a private pension plan will generally owe Wisconsin income tax on that amount.

Government Pension Exemptions

Wisconsin offers exemptions for some government retirement plans.

Some retirees who received benefits from the Wisconsin Retirement System (WRS) or other qualifying government pensions may be able to exclude those benefits from state taxable income, depending on when the service occurred and plan rules.

Eligibility rules vary by retirement system and participation dates.

IRA Withdrawals

Traditional IRA withdrawals are generally taxable in Wisconsin because they are included in federal taxable income.

This includes:

• Regular IRA withdrawals

• Required Minimum Distributions (RMDs)

• Early withdrawals

Roth IRA qualified distributions are generally not taxable because they are not included in federal taxable income.

Example:
If you withdraw $20,000 from a traditional IRA, that amount is typically taxable in Wisconsin.

401(k) and 403(b) Withdrawals

Distributions from 401(k) and 403(b) accounts are generally taxable in Wisconsin if they are taxable at the federal level.

This applies to:

• Lump-sum withdrawals

• Periodic distributions

Roth 401(k) qualified distributions are generally not taxable at the state level if they are not taxable federally.

Military Retirement Income

Wisconsin provides favorable tax treatment for many military retirement benefits.

In many cases, military retirement pay is exempt from Wisconsin state tax. Veterans’ disability benefits generally are also not taxable because they are not included in federal taxable income.

Eligibility criteria depend on specific circumstances.

Property Tax Relief for Seniors

While separate from income tax, Wisconsin offers property tax relief programs that may benefit retirees.

These may include:

• Homestead Credit (income-based)

• Veterans and surviving spouses’ property tax credit

• Lottery and gaming credit

Eligibility depends on income and property ownership.

Estate and Inheritance Taxes

Wisconsin does not have a state estate tax or inheritance tax, which can simplify estate planning for retirees.
