Both Wisconsin's tax brackets and the associated tax rates were last changed one year ago in 2023. Wisconsin's tax brackets are indexed for inflation, and are updated yearly to reflect changes in cost of living.
Wisconsin has four marginal tax brackets, ranging from 3.5% (the lowest Wisconsin tax bracket) to 7.65% (the highest Wisconsin tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket .
In Wisconsin, different tax brackets are applicable to different filing types. Married couples filing their Wisconsin income tax return jointly will usually have wider tax brackets than those filing separately or as an individual.
How do Wisconsin tax brackets work?
Technically, you don't have just one "tax bracket" - you pay all of the Wisconsin marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Wisconsin tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.
You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that. The chart below breaks down the Wisconsin tax brackets using this model:
| For earnings between $0.00 and $14,320.00, you'll pay 3.5% |
| For earnings between $14,320.00 and $28,640.00, you'll pay 4.4% plus $501.20 |
| For earnings between $28,640.00 and $315,310.00, you'll pay 5.3% plus $1,131.28 |
| For earnings over $315,310.00, you'll pay 7.65% plus $16,324.79 |
| For earnings between $0.00 and $19,090.00, you'll pay 3.5% |
| For earnings between $19,090.00 and $38,190.00, you'll pay 4.4% plus $668.15 |
| For earnings between $38,190.00 and $420,420.00, you'll pay 5.3% plus $1,508.55 |
| For earnings over $420,420.00, you'll pay 7.65% plus $21,766.74 |

Wisconsin Tax Deductions
When calculating your Wisconsin income tax, keep in mind that the Wisconsin state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.
Qualifying deductions might include an itemized deduction, the Wisconsin standard deduction, exemptions for dependants, business expenses, etc.
Remember that Wisconsin may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Wisconsin income tax return.

In addition to marginal tax brackets, one of the major features of the Wisconsin income tax is deductions. The three most common deductions encountered by taxpayers are the Wisconsin Standard Deduction, the Wisconsin Personal Exemption, and the Wisconsin Dependent Deduction. The current values of these deductions for tax year 2024 are as follows:
| Standard Deduction (Single) | Standard Deduction (MFJ) | Personal Exemption | Dependant Exemption |
|---|---|---|---|
| $13,230.00 | $24,490.00 | $700.00 | $700.00 |
The standard deduction, which Wisconsin has, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction. Essentially, it translates to $13,230.00 per year of tax-free income for single Wisconsin taxpayers, and $24,490.00 for those filing jointly.
The Personal Exemption, which is supported by the Wisconsin income tax, is an additional deduction you can take if you (and not someone else) are primarily responsible for your own living expenses. Likewise, you can take an additional dependent exemption for each qualifying dependent (like a child or family member), who you financially support.
The Federal income tax also has a standard deduction, personal exemptions, and dependant deductions, though they are different amounts than Wisconsin's and may have different rules.
