How to Start a Cottage Food Business in Wisconsin: Startup Costs and Steps

Your Startup Costs Are Lower Than You Think

A Wisconsin cottage food business operating under the Kivirist baking exemption or the Pickle Bill has no state licensing fees, no mandatory inspections, and no commercial kitchen requirements. Your actual startup costs break down to business registration, tax compliance, insurance, and packaging — many of the individual costs are modest.

Here's the realistic cost breakdown:

If you operate as a sole proprietor instead of an LLC, replace the $130 DFI filing with a $10–$25 DBA registration at your county Register of Deeds. That drops your startup below $400 — though you lose the personal asset protection an LLC provides.

Step-by-Step Setup

1. Classify your products. Before anything else, determine which exemption covers your product line. Oven-baked shelf-stable goods fall under the Kivirist exemption (no cap, broad sales channels). High-acid canned goods with pH ≤ 4.6 fall under the Pickle Bill (less than $5,000 per person, farmers markets, flea markets, and community events only). Unbaked items and refrigerated products require commercial licensing — they can't be produced at home.

2. Register your business entity. File Articles of Organization for an LLC online with the Wisconsin Department of Financial Institutions ($130). Alternatively, register a DBA with your county. Either way, apply for a free federal EIN through the IRS website — you'll need it for a business bank account and tax filings.

3. Get your seller's permit if needed. If you sell taxable products, register with the Wisconsin Department of Revenue through the My Tax Account portal ($20 BTR fee). This lets you collect sales tax on taxable items like candy and prepared foods.

4. Check local zoning. Contact your municipal zoning office to confirm your residential zone allows a home food business. Some jurisdictions require a home occupation permit; others restrict customer traffic or exterior signage. The state exemption from DATCP licensing does not override local zoning.

5. Set up labeling. Design compliant labels for every product. At minimum: product name, ingredient list (descending order by weight), allergen disclosures, and the verbatim disclaimer "This product was made in a private home not subject to state licensing or inspection." Canners also need their name, address, net quantity, and canning date on every jar, plus a point-of-sale sign.

6. Get insured. Product liability insurance through FLIP or a similar program runs about $299/year. Most farmers markets require proof of coverage before accepting your vendor application.

7. Open a business bank account. Keep business income and expenses separate from personal finances. Your EIN and LLC documentation (or DBA certificate) are all you need to open a business account at most banks.

Revenue Potential

The Kivirist baking exemption has no annual sales cap. Your revenue ceiling is determined by your production capacity, market access, and pricing — not by regulation. Home bakers in Wisconsin selling custom cakes, artisanal breads, and specialty cookies through a combination of farmers markets, online orders, and home pickup routinely build five-figure annual businesses.

The Pickle Bill's gross limit of less than $5,000 per person per calendar year is more restrictive. At market prices of $6–$12 per jar, that ceiling arrives faster than most canners expect — especially with three or four busy autumn markets on the calendar. Tracking gross revenue monthly (not quarterly) is the only way to avoid accidentally crossing the limit.

For either pathway, keep in mind: these are gross revenue figures, not profit. Ingredient costs, insurance, market fees, packaging, and fuel all come out of your top line. A near-$5,000 canning business might net $2,000–$3,000 after expenses.

What Comes Next

Once your paperwork is filed and your first products are labeled, the operational rhythm is straightforward: produce, label, sell, track revenue, file sales tax returns, and maintain your insurance.

The points where businesses stumble tend to be regulatory, not operational — using a frosting that pushes water activity above 0.85, selling canned goods from home instead of at a market, or shipping baked goods across state lines. Each of these crosses a legal boundary that can trigger enforcement action.
