How Wisconsin Income Tax Works in 2026
Wisconsin uses a progressive bracketed income tax similar to the federal system. The state’s top marginal rate reaches approximately 5.30% for 2026; lower brackets apply at the bottom of the income scale. See the Wisconsin Department of Revenue’s official 2026 rate schedule for exact dollar thresholds by filing status.
Most progressive states start from federal AGI, layer state-specific addbacks (e.g., out-of-state municipal bond interest) and subtractions (Social Security, qualified pensions, 529 contributions), then apply the bracket schedule. Credits — EITC match, child/dependent care, energy — reduce the bill dollar-for-dollar.
Federal + Wisconsin Marginal Rate Stack
State income tax stacks on top of federal income tax and FICA. The 2026 federal brackets (single filer) are:

FICA (7.65% combined) adds on top for wage income up to the Social Security wage base ($184,500 in 2026). See 2026 Federal Tax Brackets for the full schedule across all filing statuses.
Retirement Income, Social Security & Pensions
Wisconsin: Partial exemption (age / income limits apply).
Whether you live in Wisconsin during retirement matters as much as where you saved. Pre-tax 401(k) and IRA contributions reduce both federal and (in most states) state taxable income today, while Roth contributions and conversions are taxed up front. If you plan to retire in a no-income-tax or retirement-friendly state, frontloading Roth conversions before you move can permanently lock in lower rates.
