How 1099 tax works in Wisconsin
Wisconsin taxes income on 4 graduated brackets for 2026, from 3.5% up to 7.65%. Because 1099 profit stacks on top of any other income, a second source can push part of it into the next bracket.
On top of that sits the federal layer, which is the same wherever you live: self-employment tax plus federal income tax. The 1099 tax calculator hub works through how that half is built.

What the rate alone doesn't tell you about Wisconsin
Wisconsin is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.

Wisconsin 1099 tax questions
Does Wisconsin tax 1099 income?
Yes. Wisconsin taxes net profit from 1099 work the same way it taxes other income, on 4 graduated brackets topping out at 7.65%. On the $50,000 example above the state share is $2,076.

About 24% of net profit, based on the $50,000 single-filer example above ($11,808 of federal, self-employment and Wisconsin state tax combined). Your own rate moves with filing status, other income and deductions, run the calculator with your numbers.
Are there local income taxes in Wisconsin?
The estimate above models federal, self-employment and state income tax only, it does not include any city, county or school-district income tax. The 2026 dataset carries no local-tax note for Wisconsin, so check with the municipality where you live and work before relying on the state figure alone.
Does Wisconsin reciprocity help if I do 1099 work across a state line?
Usually not. Wisconsin has wage reciprocity with Illinois, Indiana, Kentucky and Michigan (exemption form W-220), but reciprocity agreements cover wages paid by an employer, not self-employment income. A 1099 worker with income sourced to another state generally still files there and claims a credit at home.
When are quarterly estimated payments due?
Federal 1040-ES payments for the 2026 tax year are due April 15, 2026, June 16, 2026, September 15, 2026, January 15, 2027. Wisconsin requires its own estimated payments; the 2026 dataset does not yet carry state-specific due dates, so confirm them with the Wisconsin tax agency.
