Wisconsin has ten marginal tax brackets, ranging from 4.60% (the lowest Wisconsin tax bracket) to 7.75% (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.
Our Wisconsin tax brackets have been updated for tax year 2013. States often adjust their tax brackets on a yearly basis, so make sure you are using the current 2013 tax brackets!

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.
You can use the income tax estimator to the left to calculate your approximate Wisconsin and Federal income tax based on the most recent tax brackets.
Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

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.
