Wisconsin income tax rates for 2026
Four brackets from 3.5% to 7.65%. The calculation starts from federal adjusted gross income with Wisconsin modifications. Each rate applies only to the slice of taxable income inside its bracket, so earning enough to reach a higher bracket never lowers your income after tax.
| Rate | Taxable income |
|---|---|
| 3.5% | $0 – $15,110 |
| 4.4% | $15,111 – $51,950 |
| 5.3% | $51,951 – $332,720 |
| 7.65% | Over $332,720 |
| Rate | Taxable income |
|---|---|
| 3.5% | $0 – $20,150 |
| 4.4% | $20,151 – $69,260 |
| 5.3% | $69,261 – $443,630 |
| 7.65% | Over $443,630 |
Heads of household use the single brackets. Married people filing separately use half of each joint threshold.
Deductions, exemptions and credits
Before the rates apply, Wisconsin allows a sliding standard deduction of up to $13,960 (single) or $25,840 (joint) that phases out as income rises and a personal exemption of $700 (single) or $1,400 (joint). The calculator uses these for the filing status you choose; dependent exemptions and credits, which lower the tax further for families, are not included.
- Wisconsin’s larger head-of-household standard deduction is approximated with the single deduction.
Worked example: $75,000 in Wisconsin
Single filer with $75,000 of income before state deductions.
Taxable income = $75,000 − $7,374 (sliding-scale standard deduction) − $700 (personal exemption) = $66,925.72
Brackets: 3.5% × $15,110.00 + 4.4% × $36,840.00 + 5.3% × $14,975.72 = $2,943.52
Wisconsin income tax = $2,943.52 — an effective rate of 3.92% and a marginal rate of 5.3%.
