Milwaukee local rules

Local income tax: No city income tax in Milwaukee.
City of Milwaukee sales and use tax (2%): Since January 1, 2024, a 2% City of Milwaukee sales and use tax applies to retail sales of taxable goods, certain digital goods, and taxable services sold to a location in the city. It stacks on the 5% Wisconsin rate and the 0.9% Milwaukee County rate.
City business license: No: the City of Milwaukee does not issue general business licenses and only licenses specific business types. A home-based business that needs one of those licenses must also get a Home Occupation Statement from Neighborhood Services.
Also worth knowing: The business-license guidance comes from the City Clerk License Division's Quick Start Guide (dated Nov. 2018), the most recent official statement found. Bartenders who serve alcohol need a Class "D" operator's (bartender's) license from the License Division (https://city.milwaukee.gov/cityclerk/license/FrequentlyAskedQuestions). No city gig-worker ordinance was found. The no-local-income-tax finding relies on the Tax Foundation's 2026 list of states with local income taxes (secondary source; no single official statement exists).

Wisconsin rules that apply in Milwaukee

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.
