The formulas
- Taxable income = income - standard deduction - personal exemptions (when applied), not below zero
- Tax from 2026 Schedule A (single, head of household), B (joint) or C (separate): 3.5% to 7.65%
- Sliding standard deduction: single $13,960 less 12% of income over $20,120 (zero from $136,453); joint $25,840 less 19.778% over $29,040; separate $12,280 less 19.778% over $13,780; head of household $18,030 less 22.515% over $20,120, then the single scale
- Exemption $700 per filer
- Wisconsin income tax = tax from the rate schedule
How it works
Tax year: 2026.
Wisconsin taxes income at 3.5% to 7.65%. Enter income before state deductions and choose whether to apply the state standard deduction and personal exemptions, or enter taxable income and switch them off. The tool computes state income tax only; credits other than those named are not applied.
Wisconsin's 2026 rates are 3.5, 4.4, 5.3 and 7.65 percent. The standard deduction slides down as Wisconsin income rises and reaches zero at $136,453 single or head of household, $159,690 joint and $75,869 separate; the tool applies the 2026 schedules. Each filer and dependent has a $700 exemption, plus $250 at 65 or over.
Local taxes: Wisconsin cities and counties do not levy a local income tax.
