Question 1

How much is Wisconsin state income tax in 2026?

Accepted Answer

Wisconsin uses a progressive income tax with four brackets ranging from 3.54% to 7.65%. The top rate of 7.65% kicks in above $276,270 in taxable income for single filers. For a $75K single filer, the effective state tax rate works out to roughly 4.2% after the standard deduction. That's higher than neighboring Minnesota's bottom bracket but lower than Minnesota's top rate of 9.85%.

Question 2

What is the Wisconsin standard deduction for 2026?

Accepted Answer

Wisconsin offers a standard deduction that varies by filing status: $12,990 for single filers, $24,070 for married filing jointly, and $18,340 for head of household. The deduction phases out at higher income levels. This is separate from the federal standard deduction and applies only to your Wisconsin state tax calculation.

Question 3

Does Wisconsin tax Social Security benefits?

Accepted Answer

No. Wisconsin does not tax Social Security benefits. However, other retirement income — including 401(k) withdrawals, IRA distributions, and most pension income — is fully taxable at the state's regular rates (up to 7.65%). That can be a significant hit for retirees with large retirement account balances. Wisconsin does offer a small retirement income exclusion for seniors with lower incomes.

Question 4

How does Wisconsin compare to neighboring states on taxes?

Accepted Answer

Wisconsin's top rate of 7.65% is higher than all its neighbors except Minnesota (9.85%). Iowa is transitioning to a flat rate around 5.7%, Illinois is flat at 4.95%, and Michigan is flat at 4.25%. However, Wisconsin's standard deduction is more generous than some states, so the effective rate for moderate earners is often lower than the bracket rate suggests. Property taxes are also relatively high at about 1.63%.

Question 5

Is Wisconsin a good state for retirees?

Accepted Answer

Not particularly. While Social Security is exempt, most other retirement income is taxed at rates up to 7.65%. Wisconsin also has high property taxes (1.63% average) and a moderate 5% state sales tax. States like Illinois (no tax on retirement income) or Michigan (tax-exempt pensions) are more retiree-friendly in the region. The main Wisconsin advantage is the Social Security exemption, but that's common across most states.
