Each category has different tax rates and brackets, so it's crucial to categorize yourself correctly to calculate your tax liability accurately.

These include the Wisconsin Earned Income Tax Credit, the Homestead Credit, and specific deductions for businesses and individuals. Thoroughly review your eligibility for these credits as they can significantly lower your tax bill.

It's also beneficial to consult with a tax professional who specializes in Wisconsin tax law for personalized guidance.
