Wisconsin Paycheck & Income Tax Calculator

How Wisconsin income tax works

Wisconsin has four brackets, and for a single filer they run 3.5% to $15,110, 4.4% to $51,950, 5.3% to $332,720 and 7.65% above. Filing jointly, the same rates apply at $20,150, $69,260 and $443,630.

Read the rates alone and Wisconsin looks ordinary — a low opening band, a long middle, a high top rate hardly anyone reaches. The rates are not the interesting part.

What makes Wisconsin different is that the standard deduction is not a fixed amount. It starts at $13,960 for a single filer, but shrinks steadily as income rises and is gone entirely by $136,453. There is also a flat $700 personal exemption per person, which does not shrink.

So a single filer on $75,000 does not shelter $13,960. They shelter $7,374.40 of deduction plus $700, or $8,074.40 in total — leaving $66,925.60 of Wisconsin taxable income and about $2,944 in state tax, an effective state rate of roughly 3.9%.

There is no local income tax anywhere in Wisconsin and no employee-side payroll levy, so these figures need nothing added.

The sliding standard deduction

This is Wisconsin’s signature mechanism, it is not shared by any neighboring state, and it is the single most common reason a Wisconsin figure comes out wrong elsewhere.

The Department of Revenue publishes it as a schedule rather than a number:

• Single — $13,960 up to $20,119 of income; above that, $13,960 less 12% of the amount over $20,120; nil from $136,453
• Married filing jointly — $25,840 up to $29,039; above that, $25,840 less 19.778% of the amount over $29,040; nil from $159,690

Both formulas close exactly on their own end point. Twelve percent of the $116,333 between $20,120 and $136,453 is $13,960 — the whole deduction, withdrawn precisely as the schedule runs out.

Note that the two withdrawal rates are not the same. A joint filer loses 19.778 cents of deduction per extra dollar against a single filer’s 12 cents. The joint deduction is larger to begin with and is taken away faster, which is why you cannot derive one status from the other by doubling.

The practical effect: a calculator that applies a flat $13,960 to a Wisconsin salary of $75,000 overstates the shelter by $6,585.60 and understates the state tax by about $349 a year. If you have seen a Wisconsin figure that looked too generous, this is almost certainly why.

Why your real marginal rate peaks in the middle

A sliding deduction does something to marginal rates that a fixed one cannot, and it is worth understanding before judging a raise.

While the deduction is still shrinking, one extra dollar of income does two things: it gets taxed, and it removes 12 cents of shelter. Your taxable income therefore rises by $1.12, not $1. Your real marginal rate is the bracket rate multiplied by 1.12:

So a single Wisconsinite on $75,000 faces 5.94% on their next dollar, while one on $140,000 — comfortably better paid — faces 5.30%. The marginal rate rises through the middle of the income range and then falls, before the top bracket eventually takes it up again.

South Carolina now does something similar for the same structural reason, and Minnesota, Wisconsin’s neighbor, does not: its deduction is flat, so its marginal rate only ever climbs. The calculator above applies the slide at every income, so these figures reflect it rather than the headline rates.

Take-home pay at every salary in Wisconsin

After federal tax, Wisconsin state tax and FICA, with the sliding deduction recalculated at each income. With no local income tax and no state payroll levy, these figures hold anywhere in the state — Milwaukee, Madison, Green Bay, Kenosha and Racine alike.

What lands in your account each payday

On $75,000 a year in Wisconsin, filing single, split across the pay schedules employers actually use.

The 7.65% almost nobody pays

Wisconsin’s top rate is 7.65%, which is high — above Minnesota’s opening band, above every rate in Illinois, Michigan, Indiana or Iowa, and enough to make Wisconsin look punitive in any table sorted by top rate.

It begins at $332,720 of taxable income for a single filer and $443,630 filing jointly.

That placement matters more than the number. The band below it, at 5.3%, runs from about $52,000 all the way up, so it covers essentially the entire professional income range. A Wisconsin doctor, engineer or software lead on $150,000 or $250,000 never reaches 7.65% at all — they sit in the same 5.3% band as someone on $60,000, and pay a lower marginal rate than a $75,000 earner still inside the deduction slide.

The gap between the third and fourth bands is also unusually wide: 5.3% to 7.65% is a jump of 2.35 percentage points in a single step, where most states move by half a point or less between adjacent brackets.

Both the brackets and the deduction schedule are adjusted for inflation every year, which is why the thresholds are odd numbers like $15,110 and $332,720 rather than round ones. That indexing puts Wisconsin with Minnesota and against Virginia and Kansas, whose figures are frozen in statute and so quietly raise real tax every year.

Dates that matter for the 2026 tax year

Wisconsin returns (Form 1) are due April 15, 2027, matching the federal deadline. Estimated payments, if required, fall on April 15, June 15 and September 15, 2026, and January 15, 2027.

The brackets and deduction schedule on this page apply to income earned between January 1 and December 31, 2026, and are taken from the Department of Revenue’s own 2026 Form 1-ES instructions.

Questions people ask

What are the Wisconsin income tax rates for 2026?

Four brackets. For a single filer: 3.5% up to $15,110, 4.4% to $51,950, 5.3% to $332,720, and 7.65% above that. Filing jointly the thresholds are $20,150, $69,260 and $443,630. These are the Department of Revenue's published 2026 figures.

What is the Wisconsin standard deduction for 2026?

It depends on your income, which is what makes Wisconsin unusual. The maximum is $13,960 for a single filer and $25,840 filing jointly, but it shrinks as income rises and reaches nil at $136,453 single or $159,690 joint. On $75,000 a single filer gets $7,374.40 of it.

How fast does the Wisconsin deduction shrink?

By 12 cents per dollar of income above $20,120 for a single filer, and 19.778 cents per dollar above $29,040 filing jointly. The two rates are genuinely different, so a couple loses theirs considerably faster per dollar than a single filer does.

Why is my real marginal rate 5.94% and not 5.3%?

Because while the deduction is sliding, an extra dollar of income is taxed and also costs you 12 cents of deduction, so your taxable income rises by $1.12. At the 5.3% rate that works out at 5.936%. Once the deduction is exhausted at $136,453 nothing more can be withdrawn, and the marginal rate drops back to 5.3%.

Is there a Wisconsin personal exemption?

Yes, a small one: $700 for yourself, $700 for a spouse on a joint return and $700 for each dependent, with an extra $250 if you are 65 or over. It is flat and does not shrink with income, so it is the only shelter left above $136,453.

Does any Wisconsin city charge a local income tax?

No. No Wisconsin municipality or county levies an income tax, so where you live in the state does not change your income tax bill.

Are Wisconsin payroll deductions taken from my paycheck?

Not by the state. Wisconsin unemployment insurance is employer-funded and the state runs no disability or paid family leave program. Beyond the state income tax, the only deductions are federal.
