Wisconsin has a four-bracket progressive individual income tax for 2025: 3.50%, 4.40%, 5.30%, and a top rate of 7.65% (top bracket starts at about $315,310 single / $420,420 MFJ). Because Section 125 salary reductions also reduce Wisconsin taxable wages, a $3,300 healthcare FSA election saves a 22% federal bracket Wisconsin employee roughly $1,225 - about $175 more than the same election would save a no-state-tax Florida peer. Matchbook models the full federal plus FICA plus Wisconsin marginal stack per household.
