Guide: Self-employment tax in Wisconsin - graduated rates and the sliding deduction
Wisconsin freelancers owe three layers of tax: federal self-employment tax, federal income tax, and Wisconsin tax. The 2025 single-filer brackets are 3.50% to $14,680, 4.40% to $50,480, 5.30% to $323,290, and 7.65% above that. 2025 Act 15 widened the second bracket, so more income is taxed at 4.40% than before.
Wisconsin has no flat standard deduction. A single filer gets up to $13,560 when Wisconsin AGI is below $19,550, reduced by 12% of AGI above $19,550, and $0 above $132,550. The personal exemption is $700 per taxpayer, spouse, or dependent, plus $250 at age 65 or older. Nonresidents and part-year residents prorate these amounts.
Worked example. On $50,000 of income, the standard deduction is $13,560 minus 12% of ($50,000 minus $19,550) = $9,906. Taxable income is $50,000 minus $9,906 minus $700 = $39,394, and the tax is 3.50% of $14,680 ($513.80) plus 4.40% of $24,714 ($1,087.42) = $1,601.22. On $100,000, the deduction is $3,906, taxable income is $95,394, and the tax is $513.80 + $1,575.20 + $2,380.44 = $4,469.44.

FAQ
Take $13,560 and subtract 12% of every dollar of Wisconsin AGI above $19,550. At $100,000 of AGI that is $13,560 minus $9,654 = $3,906. Above $132,550 the deduction is $0, so high earners get no Wisconsin standard deduction at all.
Nonresidents and part-year residents prorate the standard deduction and exemptions. Only the Wisconsin-source share of your income is taxed by Wisconsin, but the proration rules change the deduction, so check the Wisconsin Department of Revenue guidance for your situation.
No. Wisconsin starts from its own definition of income and applies its own brackets, standard deduction, and exemptions. That is why the worked example above starts from Wisconsin AGI, not from your federal return.
Federal estimated payments are generally required if you expect to owe $1,000 or more in federal tax after withholding and credits. Wisconsin has its own estimated-payment rules and forms, so check the Wisconsin Department of Revenue for its thresholds and due dates before you skip a quarter.
