Is Social Security Taxable in Wisconsin?
Is Social Security Taxable in Wisconsin?
For Wisconsin retirees, the answer is good news:
Wisconsin does not tax Social Security benefits.
Even if some of your Social Security is taxable on your federal income tax return, Social Security benefits are excluded from Wisconsin taxable income.
That distinction is important because federal and Wisconsin tax rules do not always treat retirement income the same way.
Can Social Security Still Be Taxable Federally?
Yes.
At the federal level, whether your Social Security benefits are taxable depends largely on your other income.
The IRS looks at a calculation that generally includes:
one-half of your Social Security benefits,
other taxable income, and
tax-exempt interest.
For federal purposes, benefits may begin becoming taxable when this combined amount exceeds the applicable base amount for your filing status.
For many retirees, that means income from sources such as:
traditional IRA withdrawals,
pensions,
required minimum distributions,
investment income,
wages, or
Roth conversions
can affect how much of their Social Security is taxable federally.
Why Retirement Tax Planning Still Matters in Wisconsin
The fact that Wisconsin does not tax Social Security does not mean retirement income is automatically tax-free.
Traditional IRA distributions, pensions, RMDs, investment income, and other income may still be taxable federally and may also affect your Wisconsin income tax return.
This is one reason retirement tax planning is often more useful when done before a withdrawal or other financial decision rather than after the year has ended.
For example, taking a large IRA distribution in one year could potentially increase federal taxable income and affect how much Social Security is subject to federal income tax.
A New Wisconsin Retirement Tax Break
Beginning with the 2025 tax year, Wisconsin taxpayers age 67 or older may qualify for a new retirement-income subtraction.
Eligible individuals may subtract up to $24,000 of qualifying retirement income from Wisconsin income.
For a married couple filing jointly, the subtraction may be as much as $48,000 if both spouses are at least age 67 by the end of the tax year.
Social Security itself does not use this subtraction because Wisconsin already excludes Social Security from taxable income.
The Bottom Line
Social Security benefits are not taxable by Wisconsin, but they may still be taxable federally.
Your other retirement income can play an important role in determining your overall tax liability, which is why looking at Social Security, retirement withdrawals, investments, and other income together can be valuable.
