Wisconsin taxes at a glance (2026)

Wisconsin has a graduated income tax with a standard deduction of $13,960 (single) / $25,840 (married). Wisconsin uses a 4-bracket graduated income tax for tax year 2026: 3.50%, 4.40%, 5.30%, and a top 7.65%. Brackets are inflation-adjusted annually (2026 figures shown; do not confuse with 2025 thresholds of ~$14,680/$50,480/$323,290 single). The state remains graduated — proposed flat-rate legislation was not enacted; the 2025-27 budget adjusted lower brackets. Standard deduction is a sliding scale that PHASES OUT as income rises (not a fixed amount): max $13,960 single / $25,840 MFJ shown, phasing toward $0 at higher incomes (begins phaseout ~$20,119 single / ~$29,039 MFJ). Personal exemption: $700 per filer/dependent ($1,400 MFJ), plus extra $250 if 65+. No local/city income taxes in Wisconsin. Social Security benefits are fully EXEMPT. Most other retirement income (pensions, IRA, 401k) is taxable; a limited retirement-income subtraction (up to $5,000) applies for those 65+ under AGI thresholds; certain government/military pensions are fully exempt.
