Wisconsin has a graduated income tax with 4 rates, from 3.5% up to 7.65%. Each rate applies only to the slice of taxable income inside its bracket, so moving into a higher bracket never raises the tax on income you already earned. Married couples filing jointly get wider brackets than single filers. Wisconsin gives a standard deduction of $13,960 for single filers and $25,840 for married couples filing jointly. Each filer also gets a personal exemption of $700 ($1,400 for a married couple) plus $700 for each dependent.
Wisconsin's sliding-scale standard deduction shrinks by 12% of income above about $20,120 (19.778% above about $29,040 for couples) and reaches zero at $136,453 ($159,690). The calculator applies it.

The table shows estimated 2026 Wisconsin income tax for a single filer at common incomes, using the standard deduction and no other deductions or credits. Federal income tax is shown for comparison. Every figure comes from the calculator above.

On $50,000 of income a single Wisconsin resident pays about $1,576.74 of state income tax, an effective rate of 3.15%. At $100,000 the tax is $4,427.52 (4.43%), and at $200,000 it is $9,959.36 (4.98%). State tax is smaller than federal income tax at every income shown: at $100,000 the federal bill is $13,170.00.
Married couples filing jointly get wider brackets and a larger deduction. Here is the same income range for a married couple with no children:
| Income | State income tax | Effective state rate | State bracket | Federal income tax | After all taxes |
|---|---|---|---|---|---|
| $30,000 | $103.25 | 0.34% | 3.5% | $0.00 | $27,602 |
| $40,000 | $522.47 | 1.31% | 3.5% | $780.00 | $35,638 |

| $300,000 | $15,021.11 | 5.01% | 5.3% | $49,468.00 | $219,272 |
A married couple with $100,000 of combined income pays about $3,795.42 in Wisconsin income tax, compared with $4,427.52 for a single person with the same income.
Here is every step the calculator takes for a single filer in Wisconsin with $75,000 of wages in 2026. These are the default inputs of the calculator above, so you can follow along line by line.
Every taxpayer's situation is a little different, but the order of the steps is always the same: start from income, subtract pre-tax contributions, subtract the state's deductions and exemptions, apply the brackets, and finally subtract credits.
Two different rates describe your Wisconsin tax. The marginal rate is the rate on your next dollar: 5.3% for a single filer earning $75,000. The effective rate is total state tax divided by total income: $2,943.52 ÷ $75,000 = 3.92%. The effective rate is lower because deductions, exemptions and the lower brackets shelter part of the income.
| Single income | Marginal state rate | Effective state rate |
|---|---|---|
| $30,000 | 4.4% | 1.97% |
| $40,000 | 4.4% | 2.71% |
| $50,000 | 4.4% | 3.15% |
| $60,000 | 4.4% | 3.45% |
| $75,000 | 5.3% | 3.92% |
| $100,000 | 5.3% | 4.43% |
| $150,000 | 5.3% | 4.87% |
| $200,000 | 5.3% | 4.98% |
| $300,000 | 5.3% | 5.09% |
The marginal rate is what matters for decisions such as overtime, a bonus or a raise. At $75,000, earning $1,000 more raises Wisconsin income tax by about $59.36, plus 22% federal income tax and 7.65% Social Security and Medicare.
Where you live – not only where you work – decides most of your state income tax bill. The table compares Wisconsin with its neighboring states for the same incomes, using each state's own 2026 rules.
| State | Tax on $75,000 (single) | Effective rate | Tax on $150,000 (single) | Tax on $100,000 (married) |
|---|---|---|---|---|
| Iowa | $2,198.20 | 2.93% | $5,048.20 | $2,496.40 |
| Michigan | $2,936.75 | 3.92% | $6,124.25 | $3,748.50 |
| Wisconsin | $2,943.52 | 3.92% | $7,309.36 | $3,795.42 |
| Illinois | $3,567.71 | 4.76% | $7,280.21 | $4,660.43 |
| Minnesota | $3,576.61 | 4.77% | $8,941.94 | $4,013.05 |
At $75,000, a single filer pays $2,943.52 in Wisconsin compared with $2,198.20 in Iowa and $3,576.61 in Minnesota. Living in Iowa instead would save about $745 a year at that income. Remember that sales, property and local taxes also differ from state to state, so income tax is only one part of the total cost of living.
Among all 50 states and DC, Wisconsin has the 36th-lowest state income tax for a single filer earning $75,000 in 2026 ($2,943.52), the 32nd-lowest at $50,000 ($1,576.74) and the 39th-lowest at $150,000 ($7,309.36). For a married couple with $150,000 of income it ranks 43rd-lowest ($6,969.54). The 9 states without a wage tax share first place, so a rank of 10 is the lowest possible for a state that taxes wages.
A married couple filing jointly with $120,000 of wages and two children under 17 pays an estimated $4,990.87 in Wisconsin income tax for 2026, compared with $5,065.07 for the same couple without children. Their federal income tax is $5,640.00 after $4,400.00 of child tax credits, and they keep about $100,189 after all taxes.
A single parent filing as head of household with $60,000 of wages and one child pays about $2,038.74 in Wisconsin tax and $1,748.00 in federal income tax. Head-of-household filers get a larger federal standard deduction of $24,150 and wider federal brackets. For the state part the calculator uses the single-filer brackets and deductions, which is how many states treat head of household, but check your state form if it has separate head-of-household tables.
Pre-tax retirement contributions lower state tax too. A single filer earning $90,000 who contributes $6,000 to a 401(k) cuts Wisconsin income tax by $356.16 and federal income tax by $1,320.00, so the $6,000 contribution costs only about $4,324 in take-home pay.
The brackets above are only part of your Wisconsin tax bill. These Wisconsin rules change what you actually owe, checked against state and Tax Foundation sources in October 2026.
| Deduction and exemption | Sliding-scale standard deduction up to $13,960 single (phases out with income) plus $700 personal exemption. |
|---|---|
| Credits worth knowing | State EITC (4%–34% of federal, families with children only, refundable); Homestead Credit. |
| Local income tax | None. Only the state rate applies to wages. |
| Capital gains | 30% exclusion of net long-term capital gains (60% for farm assets). |
| Deadline for 2025 returns | April 15, 2026. |

Every state starts from a slightly different number. This is exactly how Wisconsin turns $75,000 of wages into a tax bill for 2026:
Wisconsin tax at other incomes (wages only, 2026):
| Income | Single | Single rate | Married jointly | Married rate |
|---|---|---|---|---|
| $35,000 | $838 | 2.39% | $313 | 0.89% |

| $100,000 | $4,428 | 4.43% | $3,795 | 3.80% |
| $250,000 | $12,609 | 5.04% | $12,371 | 4.95% |
Wisconsin deduction rules: Sliding-scale standard deduction up to $13,960 single (phases out with income) plus $700 personal exemption.
A $1,000 raise in Wisconsin: going from $75,000 to $76,000 adds $220 of federal income tax, $59 of Wisconsin tax and $76.50 of Social Security and Medicare, so you keep about $644 of it.
| Filing status at $75,000 | Federal income tax | Wisconsin tax | Total income tax | Effective rate |
|---|---|---|---|---|
| Single | $7,670 | $2,944 | $10,614 | 14.15% |
| Head of household | $5,748 | $2,944 | $8,692 | 11.59% |
| Married filing jointly | $4,640 | $2,320 | $6,960 | 9.28% |
For a single filer, Wisconsin tax is 27.73% of the combined federal and state income tax bill at $75,000.
State income tax for a single filer in Wisconsin and its neighbors (wages only, 2026):
| State | $50,000 | $100,000 | $200,000 |
|---|---|---|---|
| Wisconsin | $1,577 | $4,428 | $9,959 |
| Michigan | $1,874 | $3,999 | $8,249 |
| Minnesota | $1,877 | $5,277 | $12,867 |
| Iowa | $1,248 | $3,148 | $6,948 |
| Illinois | $2,330 | $4,805 | $9,755 |
In other words, moving from Michigan to Wisconsin on $100,000 costs about $428 a year in state income tax; moving from Minnesota to Wisconsin on $100,000 saves about $849 a year in state income tax; moving from Iowa to Wisconsin on $100,000 costs about $1,279 a year in state income tax; moving from Illinois to Wisconsin on $100,000 saves about $378 a year in state income tax.
On $75,000 of wages your Wisconsin tax for 2026 is about $2,944, so an employer paying every two weeks should withhold close to $113.21 per paycheck ($245.29 a month). That amount is driven by the Form WT-4 you gave your employer, not the federal W-4.
Side income: $10,000 of freelance or rental income on top of that salary adds about $594 of Wisconsin tax and $2,200 of federal income tax. Because nothing is withheld from it, pay about $148 to Wisconsin each quarter, or raise your paycheck withholding, to avoid an underpayment penalty.
