Wisconsin taxes income at graduated rates with a top marginal rate up to about 7.65%. Pre-tax traditional 401k deferrals generally reduce both federal and Wisconsin taxable income, which lowers current state tax for many workers. Traditional 401k withdrawals are generally subject to Wisconsin income tax in retirement. Roth 401k tradeoffs depend on federal and Wisconsin rules — consult a tax professional for your situation.
| Monthly Contribution | Years | 7% Return | Est. Balance |

| $500 | 20 | 7% | ~$262,000 |
| $1,000 | 20 | 7% | ~$524,000 |
| $2,042 ($24,500/yr) | 20 | 7% | ~$1,071,000 |

Traditional 401k deferrals save federal and generally Wisconsin tax now at rates up to about 7.65% at the top bracket. Roth 401k trades that upfront savings for potential federally tax-free qualified withdrawals. Typical 3–6% employer matches are often traditional dollars. Many workers capture the full match first, then split additional savings based on expected retirement tax rates.
The IRS sets the same limits nationwide: $24,500 in employee deferrals for 2026. Workers aged 50 and older can add an $8,000 catch-up for $32,500 total. Optional higher catch-ups may apply at ages 60–63 under federal rules. Combined employee and employer contributions can reach up to $72,000 in 2026 (plus catch-ups where allowed).
Wisconsin has progressive income tax with a top marginal rate up to about 7.65%. Traditional 401k salary deferrals generally reduce both federal and Wisconsin taxable income, lowering current state tax. Distributions from traditional 401k accounts are generally taxable in Wisconsin in retirement.
Many Wisconsin employers match about 3% to 6% of salary when you defer enough to earn the full match. Always contribute enough to capture the full match. The combined employee plus employer limit is $72,000 in 2026 before age-based catch-ups.
Traditional 401k lowers federal and generally Wisconsin taxable income now — valuable when marginal rates approach 7.65%. Roth 401k uses after-tax dollars but can provide federally tax-free qualified withdrawals; confirm Wisconsin treatment of Roth distributions with a tax advisor.
Total contributions from you and your employer generally cannot exceed $72,000 in 2026 (plus allowed catch-ups). Employer matching dollars count toward that cap.
Many employers offer Roth 401k. After-tax contributions grow federally tax-free if qualified; weigh current Wisconsin tax on Roth deferrals against your expected retirement tax picture.
