Freelancers in Madison, WI: taxes and retirement for 2026

For freelance designers, developers, writers and other 1099 professionals in Madison, WI. Wisconsin has a graduated state income tax for 2026: 3.5% to 7.65% (top rate starts at $332,720 for single filers). Here are the 2026 rules, a worked example and the official sources.

What's different in Madison

Local income tax: No city income tax in Madison.
Madison Transient Room Tax (MGO 4.21): Madison charges a 10% room tax on lodging. Anyone renting rooms or lodging in Madison, including short-term rental hosts, must get a Transient Room Tax permit from City Treasury and file quarterly returns due Jan. 31, Apr. 30, July 31 and Oct. 31.
Also worth knowing: No city income tax. The 10% room tax rate is stated in the city's Room Tax Overview (https://www.cityofmadison.com/finance/documents/RoomTaxCommissionOverview.pdf); it rose from 9% under ORD-17-00110 (2017), and we found no later change. The city issues licenses only for specific business types (https://www.cityofmadison.com/clerk/licenses-permits), not a general business license. Short-term rentals (Tourist Rooming Houses) need a Zoning TRH Permit ($300 one-time application fee plus $100 yearly renewal), a Room Tax Permit and a Public Health Madison & Dane County license. The home must be the host's primary residence, both while renting and for the 12 months before, and rentals are capped at 30 days per licensing year (July 1-June 30) when the host is away (https://www.cityofmadison.com/dpced/building-inspection/zoning-signs/trh/regulations). We found no local gig-worker pay laws.

Wisconsin rules for freelancers

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.
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.

Federal rules for 2026

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

All income counts, form or no form

Clients and marketplaces send 1099-NEC or 1099-K forms only above IRS reporting thresholds, but every dollar of freelance income is taxable whether or not a form arrives.

Home office and tools

If you use part of your home regularly and only for work, the simplified home-office deduction is $5 per square foot up to 300 square feet. Software, equipment and a business share of your phone and internet are deductible too.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

A worked example

A freelancer with $85,000 of net profit in 2026
Self-employment tax	$12,010
Self-employment tax per quarter	$3,003
Solo 401(k) maximum	$40,299
SEP IRA maximum	$15,799

Federal figures only. Income tax comes on top; the quarterly tax calculator estimates both. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
