From your first batch to your first sale — here's the complete roadmap for launching a Wisconsin cottage food business. Structure, taxes, pricing, and exactly where to sell, all in one place.
Work through this checklist in order. Some steps are legally required; others are strongly recommended. All of them contribute to a more successful, sustainable business.
Most Wisconsin cottage food sellers start as sole proprietors — it costs nothing and gets you selling immediately. An LLC is worth considering once your revenue grows or you want clearer liability protection. Here's the honest comparison.
Our recommendation: Start as a sole proprietor and sell for your first season. Once you've proven your products, built a customer base, and are generating consistent revenue — or if someone asks if you're "a real business" — then consider forming an LLC. The liability protection becomes more meaningful as your operation grows.
If you're operating as a sole proprietor under a name other than your own legal name, you need a DBA — "Doing Business As" — also called a trade name or fictitious name registration in Wisconsin.
Search the WI DFI business name database to confirm your chosen name isn't already registered: dfi.wi.gov
Submit a Registration of Firm Name application with the Register of Deeds in your county. Fee: typically $10–$20. Find your county office at the Wisconsin Counties Association.
You can also file a voluntary trade name registration with the WI Department of Financial Institutions for broader statewide notice. This is optional but gives you a formal state record.
Take your DBA registration to your bank to open a business checking account in your business name. Most banks require the DBA document plus your EIN or SSN.
A DBA registration is a public record that identifies who is behind the business name — it does not give you exclusive rights to the name beyond common law. It also does not protect you from someone in a different county using a similar name. For broader name protection, consider a Wisconsin or federal trademark registration — a separate and optional process.
As a self-employed food seller in Wisconsin, you have both federal and state tax obligations. Here's a clear breakdown of what applies to you.
Sole proprietors pay self-employment tax (Social Security + Medicare) on net business earnings. The rate is:
of net self-employment income. Half is deductible on your federal return. You'll owe this tax if your net earnings exceed $400 in a year. File Schedule SE with your Form 1040.
Wisconsin taxes self-employment income as personal income. Business profit flows to your personal Wisconsin return. The top marginal rate is:
Wisconsin has a graduated rate structure — lower rates apply to lower income brackets. No separate self-employment tax beyond state income tax. No franchise or business privilege tax for LLCs.
Wisconsin's base sales tax rate is 5% (plus up to 0.5% county tax). However, most food sold for home consumption is exempt — including most baked goods, jams, and candy sold by grocery-style retailers.

If you expect to owe more than $500 in Wisconsin income tax, you may need to make quarterly estimated tax payments to the DOR. Federal estimated payments are due quarterly if you'll owe more than $1,000.
Dates: April 15, June 15, September 15, January 15. Start setting aside 25–30% of profit from each sale as a tax reserve.
As a sole proprietor, these common expenses reduce your taxable income: ingredients, packaging and labels, market fees and booth rentals, food safety training, mileage to/from markets, kitchen equipment (pro-rated), and business insurance.
Keep all receipts. A simple spreadsheet or bookkeeping app tracks this easily.
Open a separate checking account for your business as soon as you start collecting revenue. This makes bookkeeping dramatically simpler and is the clearest line between personal and business finances — critical if you ever form an LLC.
Most Wisconsin banks and credit unions offer low-fee business checking accounts for sole proprietors.
Many cottage food sellers underprice their work — especially when starting out. Here's a practical framework for pricing that covers your costs, pays for your time, and lets your business grow.
Weigh or measure every ingredient in a batch and calculate its per-unit cost. Don't estimate — precision here directly determines your profit margin. Include spices, extracts, and even a small allowance for waste and spoilage.
Track your active production time (not just oven time) and value it at a rate you feel good about — at least $15–$20/hour to start. Your time is real and has real value. If you can't afford to pay yourself, your price is too low.
Visit your target farmers market before applying. What are other bakers charging for similar items? What's the quality level? Price at or slightly above comparable vendors if your quality justifies it — don't race to the bottom.
Market booth fees, packaging materials, gas to the market, labeling costs, and food safety certification fees are all real costs of doing business. Spread them across your units sold to get an accurate cost picture.
Round to clean numbers — $5, $7, $8, $12 — rather than $4.73 or $7.25. Clean prices are easier for customers to pay and for you to make change. Use $5 increments at markets for easy cash transactions.
If you consistently sell out before the market closes, your prices are too low. Raise them by 10–15% and see what happens. Your repeat customers will follow you — they're buying your specific product, not just a price point.
Wisconsin minimum wage context: As of 2026, Wisconsin's minimum wage is $7.25/hour (the federal minimum). Most cottage food sellers should aim to pay themselves at least $15–$25/hour for skilled production work. If your current prices don't support that, recost your recipes or raise your prices — not lower your standards.
Wisconsin's cottage food framework gives you several venues to reach customers. Each has different advantages, effort levels, and compliance considerations.
Not permitted under cottage food exemptions: Wholesale to grocery stores, gift shops, or retail chains. Sales to restaurants or food service. Consignment arrangements. Any sales outside Wisconsin. These all require a food processing plant or retail food establishment license from DATCP.
