How much do I take home in Wisconsin? — short answer first

Wisconsin runs a 4-bracket progressive income tax — 3.5% to 7.65% — with the top bracket at $315,310 single / $420,420 joint (2024 base, projected modestly higher for 2026 with inflation indexing). The 7.65% top rate is materially higher than its Midwest peers (Illinois 4.95% flat, Indiana 2.95% flat, Michigan 4.25% flat) — Wisconsin sits closer to Minnesota in tax burden. Wisconsin has no local income tax; Milwaukee, Madison, Green Bay, and Eau Claire all fund services through property tax. Reciprocity with Illinois, Indiana, Kentucky, and Michigan covers most Wisconsin cross-border workers; the southern Wisconsin / northern Illinois corridor is the densest reciprocity-driven labor market in the country.

How Wisconsin taxes payroll in 2026

Wisconsin levies a 4-bracket progressive individual income tax under §71.06 Wis. Stats. Brackets for single filers: 3.5% on the first $14,320 of taxable income; 4.4% on $14,321-$28,640; 5.3% on $28,641-$315,310; and 7.65% above $315,310. Married-filing-jointly thresholds are larger: 3.5% to $19,090; 4.4% to $38,190; 5.3% to $420,420; 7.65% above. Married-filing-separately thresholds are half the single values. Wisconsin updates bracket thresholds annually for inflation — the 2024 values shown are the base; 2026 projected ~3-5% higher. The state's 7.65% top rate is materially higher than its Midwest peers (IL 4.95% flat, IN 2.95% flat, MI 4.25% flat, MN 9.85% top) — Wisconsin sits closer to Minnesota in income-tax burden, leading some retirees and high earners to favour neighbouring flat-tax states. Wisconsin's standard deduction phases out at higher income levels — the maximum is $13,230 single / $24,490 joint (2024 base), but the deduction is reduced linearly as AGI rises, fully phasing out around $115K single / $144K joint. This means high-income filers effectively get no standard deduction, raising their effective rate above the headline 7.65%. Wisconsin has no local income tax — Milwaukee, Madison, Green Bay, and Eau Claire all fund services through property tax (effective rate ~1.65% statewide, among the higher Midwest values) and 5-6.5% combined sales tax. Wisconsin maintains reciprocity agreements with Illinois, Indiana, Kentucky, and Michigan — covering most Wisconsin cross-border workers. The southern Wisconsin / northern Illinois corridor (commuters between Kenosha/Racine and northern Chicago suburbs) is one of the densest reciprocity-driven labor markets in the US.

Wisconsin state income tax brackets (single filer, 2026)

Taxable income up to	Marginal rate
$14,320	3.50%
$28,640	4.40%
$315,310	5.30%
Above prior threshold	7.65%

Standard deduction (single): $13,230 · top marginal rate 7.65%. Married filing jointly + head of household brackets follow the same shape with adjusted thresholds.

Wisconsin city callouts

Milwaukee — Property tax ~2.18% effective in Milwaukee County (among the highest in WI); 5.5% combined sales tax; manufacturing + healthcare jobs anchor.
Madison — Property tax ~1.78% effective; 5.5% combined sales tax; state capital + research university drive professional/government job density.
Kenosha + Racine — Property tax ~2.0% effective; daily commuter rail to Chicago; reciprocity makes IL income work frictionless.

Reciprocity + multi-state notes

Wisconsin has reciprocity agreements with Illinois, Indiana, Kentucky, and Michigan. Cross-border workers file only state-of-residence; the working state does not withhold income tax. The southern Wisconsin / northern Illinois corridor (Kenosha-to-Chicago) is one of the densest reciprocity-driven labor markets in the US.

How to use this calculator

Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Wisconsin brackets.
Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
Using the wrong filing status for state tax. Wisconsin uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
Ignoring multi-state implications. If you work in Wisconsin but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Wisconsin.

Frequently asked questions

Why is Wisconsin's top tax rate higher than Illinois?

Wisconsin runs a progressive 4-bracket schedule with a 7.65% top rate above $315K (single) — materially higher than Illinois' 4.95% flat. The 7.65% rate has held since 2013; political pressure to flatten or cut has not produced legislation. Most Wisconsin workers earning under $315K pay an effective rate of 4-5% — closer to Illinois — but the top bracket is meaningfully harsher.

Does Wisconsin's standard deduction phase out?

Yes — Wisconsin's standard deduction phases out linearly as AGI rises. Maximum is $13,230 single / $24,490 joint (2024 base); the deduction is fully phased out around $115K single / $144K joint. High earners effectively get no standard deduction, raising their effective rate above the headline 7.65%. This is a quirk that catches transplants from flat-tax states by surprise.

I live in Kenosha but work in Chicago — what do I pay?

Wisconsin-Illinois reciprocity means you owe only Wisconsin tax on your wages — Illinois does not withhold. Submit Form IL-W-5-NR to your Chicago-based employer to halt IL withholding. You'll file only the Wisconsin Form 1 return. Kenosha-to-Chicago commuting is one of the densest reciprocity-driven labor markets in the US, with thousands of daily WI→IL commuters.

Are there any local income taxes in Wisconsin?

No — Wisconsin has no local income tax at any city, county, or municipal level. Milwaukee, Madison, Green Bay, and Eau Claire all fund services through property tax (effective ~1.65% statewide, among the higher Midwest values) and 5-6.5% combined sales tax (5% state + 0.5-1.5% county). This is rare for high-tax states (NY, OH, MD all have local levies).
