How to Use This Calculator
Enter your income, filing status, and any deductions. The calculator computes your Wisconsin state income tax alongside your federal tax, showing exactly how much goes to each and what you take home.
The most useful thing to try? Compare different income levels to see how Wisconsin's brackets affect your tax bill, then look at how combined federal + state taxes shape your total take-home pay.
Here's what each field means:
Annual Income is your total earnings before any taxes. Include wages, freelance income, investment income, and any other sources.
Filing Status determines which set of tax brackets and deductions apply. Wisconsin uses filing statuses similar to the federal system — single, married filing jointly, married filing separately, and head of household.
Wisconsin Income Tax: What You Need to Know
Wisconsin uses a progressive income tax system with rates ranging from 3.50% to 7.65%. Like the federal system, this means your income is taxed in layers — each bracket only applies to the income within that range, not your entire income.
Wisconsin Tax Brackets (Single Filers)
| Taxable Income | Tax Rate |
|---|---|
| $0 - $14,320 | 3.50% |
| $14,320 - $28,640 | 4.40% |
| $28,640 - $315,310 | 5.30% |
| $315,310+ | 7.65% |
Married Filing Jointly
| Taxable Income | Tax Rate |
|---|---|
| $0 - $19,090 | 3.50% |
| $19,090 - $38,190 | 4.40% |
| $38,190 - $420,420 | 5.30% |
| $420,420+ | 7.65% |
A Real Example
Let's say you're a single filer earning $70,000 in Wisconsin. After applying the standard deduction of $13,230 (phases out at higher incomes), your income flows through each bracket:
Your approximate Wisconsin state income tax would be around $3,250, for an effective state tax rate of about 4.6%.
Remember, this is just the state portion. You'll also owe federal income tax and FICA taxes on top of this.
Deductions and Exemptions

What's Unique About Wisconsin
Wisconsin's 5.30% bracket covers a huge range ($28,640 to $315,310 for single filers), meaning most Wisconsinites pay this rate on the majority of their income. The 7.65% top rate only kicks in at high incomes. Wisconsin has its own standard deduction that phases out as income rises — once your AGI exceeds about $120,540 (single), the standard deduction begins to shrink. Wisconsin does not tax Social Security benefits. The state offers a sliding-scale standard deduction that provides the most benefit to middle-income earners.
Recent Changes
Wisconsin reduced its second bracket rate and adjusted thresholds in recent years. There are ongoing discussions about further tax reform and rate reductions.
