Wisconsin rules that apply

State income tax (2026)

Wisconsin has a graduated state income tax for 2026: 3.5% to 7.65% (top rate starts at $332,720 for single filers). Rates are percentages. 2026 single-filer brackets: 3.5% up to $15,110; 4.4% up to $51,950; 5.3% up to $332,720; 7.65% above that. 2025 Wis. Act 15 set new brackets for tax years after 2024 and created a retirement-plan and IRA distribution subtraction for people 67 or older: up to $24,000 ($48,000 on a joint return when both spouses qualify). Anyone who takes that subtraction can't claim the credits listed in Wis. Stat. §71.10(4) that year (Act text: https://docs.legis.wisconsin.gov/2025/related/acts/15.pdf).

State estimated tax

You must pay 2026 estimated tax if you expect to owe at least $500 after withholding and credits, and your withholding will be less than the smallest of these: 90% of your 2026 tax, 100% of your 2025 tax, or 90% of your annualized 2026 tax. Same dates as federal: April 15, June 15, and September 15, 2026, and January 15, 2027. Farmers and fishers may pay once by January 15 or file and pay by March 1. Form 1-ES.

Minimum wage (2026)

$7.25 an hour; tipped cash wage $2.33 an hour. Rates unchanged since July 24, 2009. Opportunity employees (under 20, first 90 days) may be paid $5.90, or $2.13 if tipped. Cities, villages, towns, and counties may not set their own minimum wage (Wis. Stat. §104.001).

Unemployment insurance contractor test (control plus 6 of 9 conditions)

For unemployment insurance, a worker for a general private employer counts as an independent contractor only if they are free from the employer's control or direction. They must also meet at least 6 of 9 conditions, such as holding themselves out as a business, having multiple contracts, carrying their own main expenses, facing profit or loss, and not depending economically on one employer.

Worker's compensation nine-requirement test (Wis. Stat. §102.07(8))

For worker's compensation, a worker must meet all nine requirements to count as an independent contractor. These include running a separate business, having a federal EIN (or having filed business or self-employment returns the prior year), working under specific contracts, and being paid per job, by commission, or by bid. Missing even one makes the worker an employee.

Construction-industry misclassification penalties

Construction employers, including painting and drywall-finishing businesses, that knowingly and intentionally misclassify employees as independent contractors face fines. The civil penalty is $500 per misclassified employee, up to $7,500 per incident. Pressuring workers into contractor status costs $1,000 per person, up to $10,000 a year. Repeat offenders who were already penalized can face a criminal fine of $1,000 per misclassified employee, up to $25,000.
