Wisconsin Income Tax: Graduated Brackets Up to 7.65%
Wisconsin uses a progressive income tax system with 4 brackets. Rates range from 3.5% to 7.65%, with higher income taxed at higher rates. Wisconsin allows a deduction for up to $12,760 of retirement income.
Like federal taxes, Wisconsin's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), Wisconsin residents can face a total marginal rate of up to 44.65% on their highest dollars of income.
Wisconsin Tax Brackets for 2026 (Single Filer)
The Wisconsin income tax brackets for single filers are:
- 3.5% on income from $0 to $14,320
- 4.4% on income from $14,320 to $28,640
- 5.3% on income from $28,640 to $315,310
- 7.65% on income over $315,310
Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your Wisconsin Tax
Maximize pre-tax retirement contributions to reduce both federal and Wisconsin taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). If Wisconsin conforms to federal deductions, your standard deduction and itemized expenses also reduce your state tax liability.
