Wisconsin LLC Taxes Explained: 3.5%–7.65%
Wisconsin uses four individual brackets and permits a separate elective entity-level tax. Capital-gain exclusions depend on the asset and taxpayer.
For 2026, rates are 3.5%, 4.4%, 5.3% and 7.65%. Single/head-of-household thresholds are $15,110 / $51,950 / $332,720; married joint $20,150 / $69,260 / $443,630; married separate $10,080 / $34,630 / $221,820. These apply to Wisconsin taxable income, after applicable deductions and adjustments. Part-year/nonresident proration needs separate treatment. An eligible partnership or S corporation may elect annually to pay Wisconsin entity-level tax at 7.9%, using the applicable Form 3/Schedule 3-ET or Form 5S/Schedule 5S-ET. Follow the entity’s election, consent and extended-return-deadline instructions. Owners generally exclude their proportionate electing-entity items from Wisconsin adjusted gross income; do not treat this as an ordinary refundable owner credit.

The Capital Gains Exclusion
Wisconsin generally excludes 30% of qualifying net long-term capital gain on assets held more than one year. The 60% exclusion is for qualifying farm assets held more than one year. It is not a blanket 60% exclusion for all investment gains; entity elections and other adjustments can affect treatment.

Federal S-corporation status and Wisconsin’s entity-tax election are separate choices. Review reasonable compensation, payroll, filing costs and owner treatment using actual facts.
