A bakery counter with loaves and pastries, How to Start a Bakery Business in Wisconsin

How to Start a Bakery Business in Wisconsin

Last verified: November 10, 2026

A Wisconsin bakery turns on one early question: will you bake in a licensed commercial space, or at home under the state's home baker rule? The answer decides whether you need a retail food license, plan approval and a certified food manager before you sell a loaf. This guide covers the licensed bakery. If you plan to bake at home and sell only to consumers, start with our cottage food guide; if your counter will run on espresso as much as pastry, our coffee shop guide covers the drink side.

Step 1: Decide Between the Home Baker Rule and a Licensed Bakery

DATCP's home baker page says court orders stop the agency from enforcing food licensing against home producers who sell baked goods that are not potentially hazardous directly to consumers. The same page says that "all commercial kitchen baking businesses" must follow ATCP 70 (wholesale food manufacturing) or ATCP 75 (retail food establishments and the Wisconsin Food Code) (DATCP: licenses and homemade baked goods, Wayback snapshot October 8, 2026). All three tests must hold for the home rule to apply:

  • Baked: exposed to dry heat above 140°F in a closed chamber such as an oven.
  • Not potentially hazardous: the finished, ready-for-sale product must not need temperature control. A cream, custard or cheese filling is where bakers usually cross this line.
  • Direct to consumers: DATCP says a business that wholesales baked goods must be licensed.

Our position: plan for the license if you want a storefront, wholesale accounts or any filled and refrigerated product. The home rule is a way to test recipes and demand, not a bakery business model. The rest of this guide assumes a licensed bakery. The cottage food guide covers the home rule in detail, including how the court cases changed it.

Step 2: Plan the Kitchen and Get the Retail Food License

Wisconsin's retail food rule, ATCP 75.06(1), says no one may operate a retail food establishment without a valid license from DATCP or its agent. Each location needs its own license, and a license cannot be transferred between persons or places. Licenses expire June 30; one first issued between April 1 and June 30 runs to June 30 of the following year (ATCP 75.06, Cornell Legal Information Institute copy read November 10, 2026).

The exemption in ATCP 75.063(1) covers only establishments that sell packaged foods or fresh fruits and vegetables, sell no temperature-controlled food and do no food processing. A bakery that mixes and bakes on site is processing food, so we read the exemption as not covering you. Ask the licensing office if your plan is unusual.

Order of Work

  1. Find your licensing office. The license comes from DATCP or an agent, usually a local health department. Call (608) 224-4923 or email [email protected] to learn which one covers your address. The rule's note says an agent sets its own fee schedule, so ask for it.
  2. Get plan approval before you build. ATCP 75.075 requires a new or extensively remodeled establishment to submit a plan and receive approval before construction starts. The submission includes equipment layout plans, equipment schedules, a description of your food processing operations, your menu, and copies of other state, county or municipal approvals. The agency has 30 days after it has complete information to approve or deny (ATCP 75.075).
  3. Pass the pre-licensing inspection. The agency may not license a new establishment until it has inspected it and you have paid the fees, including any pre-licensing fee (ATCP 75.06(5)).

What the License Costs

The annual license fee depends on a category the agency assigns from a points table. A bakery that does not serve meals pays the first column below; if the agency classifies part of your operation as serving meals, the second column applies.

License category Not serving meals Serving meals
Prepackaged TCS food only $45 $105
Simple $60 (final product is non-TCS) or $190 (TCS) $230
Moderate $265 $330
Complex $685 $540

Source: ATCP 75.08, Table B, Cornell Legal Information Institute copy read November 10, 2026. The serving-meals figures match DATCP's own retail food establishments serving meals page (Wayback snapshot June 10, 2026). The Cornell copy carries a 2020 register note, so confirm the current amount with your licensing office. Table B also sets pre-licensing inspection, reinspection and late fees. TCS means time/temperature control for safety food, which is food that needs refrigeration or hot holding.

How the category works out for a bakery is our reading of the points in Table A, not a DATCP ruling. A shop that does not serve meals and has sales between $25,000 and $1,000,000 scores 0.5. Mixing and baking counts as food processing for 1 more point, and taking customer pre-orders such as custom cakes adds 1 more, for 2.5. That is the top of the Simple category (2.5 or fewer). A walk-in cooler holding cream-filled items for cold holding adds another point, and the shop moves to Moderate. The agency assigns the category, and you can ask it to reconsider within 30 days of the assignment (ATCP 75.08(1)(c)). Ask for the classification in writing before you sign a lease.

Step 3: Name a Certified Food Protection Manager

DATCP says most licensed food establishments must have at least one manager or operator certified in food protection. Someone with the credential must be in place within 90 days after you open, and the exam must be passed again every 5 years (small operators with 5 or fewer food handlers may use a recertification course under conditions DATCP lists). DATCP names narrow exemptions for prepackaged-only operations, transient events and micro markets. We found none that fits a bakery that bakes on site (DATCP: food manager requirements, Wayback snapshot August 13, 2026).

That page describes the manager credential and does not describe a separate state card for every worker. A local agent may add its own rules, so ask your licensing office what it expects from bakers and counter staff.

Step 4: Choose Your Business Structure

For a single-location bakery with no outside investors, we would start with an LLC: it separates your personal assets from the business, and the tax paperwork stays simple. For federal tax, the IRS treats a one-member LLC as a disregarded entity and a multi-member LLC as a partnership unless the LLC files Form 8832 to elect corporate treatment (IRS: limited liability company). Owners report the profits on their own Wisconsin returns; for tax year 2026 the individual rates run from 3.5% to 7.65% (Wisconsin Form 1-ES instructions, snapshot of August 17, 2026). A corporation pays the 7.9% franchise or income tax, with an economic development surcharge when gross receipts from all activities reach $4 million (DOR corporation FAQ, snapshot of October 11, 2026). A CPA should confirm which structure fits your numbers.

If you stay a sole proprietor and sell under a bakery name, Wisconsin does not require a registration: the Wisconsin SBDC says state statutes do not require one for a sole proprietorship (Wisconsin SBDC business FAQ, snapshot of July 13, 2026). You may register the name voluntarily with DFI as a tradename for $15, effective 10 years (DFI trademark information, snapshot of August 19, 2026).

Step 5: Reserve the Name and File With DFI

Wisconsin entity filings go to the Department of Financial Institutions (DFI), not the Secretary of State (DFI business entities, snapshot of October 13, 2026). Search the DFI business entity search first. An LLC name must contain "limited liability company," "limited company," "LLC" or "LC" (Wis. Stat. 183.0112(1), read in the October 22, 2026 snapshot of chapter 183). A name reservation is optional: $15 for 120 days for an LLC or business corporation. Use it only if you need to hold the name while you negotiate a lease or wait on plan approval.

File Articles of Organization (Form 502) through the DFI online filing portal or the Wisconsin One Stop Business Portal, which can also start your DOR and unemployment insurance registrations for an LLC or corporation. The LLC fee is $130 online or $170 on paper. A business corporation files Articles of Incorporation (Form 2) for $100. Optional expedited handling adds $100 for next-business-day action, and the DFI counter takes requests for $250 (four hours) or $500 (one hour) (DFI fee schedule, snapshot of October 19, 2026; the $130 amount is also in Wis. Stat. 183.0122).

Every LLC and corporation needs a registered agent and a registered office in Wisconsin. The agent is a Wisconsin resident or an entity whose business office is the registered office. That office must be an actual physical street address, not solely a P.O. box, mailbox service or answering service, and the filing needs the agent's email address. Changing the agent or office costs $10 online or $25 on paper (DFI business entity FAQ, snapshot of October 17, 2026).

You can file yourself or use a formation service. Northwest Registered Agent lists LLC formation at $39 plus the state filing fee (Northwest Registered Agent pricing, checked November 5, 2026). BetterLegal lists $299 plus the state filing fee (BetterLegal pricing, checked November 5, 2026) and sells a registered agent subscription at $12.50 a month or $120 a year (BetterLegal pricing, checked November 5, 2026). Our Wisconsin LLC services comparison sets that against filing through DFI yourself.

An LLC's annual report costs $25 online or $40 on paper. The first one is due in the year after the calendar year you formed, in the quarter that contains your anniversary date (DFI fee schedule and FAQ above). See our Wisconsin annual report guide. It is not a first-year cost.

Step 6: Get an EIN

The IRS issues an Employer Identification Number free: its EIN page says you never have to pay a fee, and the online tool issues the number in minutes. Apply only at irs.gov/ein. Our Wisconsin EIN guide covers the details.

Step 7: Register for a Seller's Permit and Learn the Prepared-Food Rule

Wisconsin's seller's permit is required for anyone making taxable sales unless all of their sales are exempt (DOR Publication 201, snapshot of August 28, 2026). Most bakeries have at least some taxable sales, such as hot coffee, so plan to register. DOR asks you to apply at least three weeks before you open. Register through the DOR business tax registration portal. The fee is $20 and covers two years; renewal is $10 every two years (DOR business tax registration FAQ, snapshot of October 9, 2026). Our Wisconsin seller's permit guide has the full process.

The state sales tax rate is 5%. Most counties add 0.5% (Waukesha and Winnebago do not), Milwaukee County adds 0.9%, and the City of Milwaukee adds 2% (DOR tax rates, snapshot of October 26, 2026). Our sales tax by county page has the rest.

The part specific to bakeries is what you charge tax on. Food and food ingredients are generally exempt from Wisconsin sales tax, but prepared food, candy and soft drinks are taxable, and DOR's bakery publication gives a test for bakery items. Start at the top and stop at the first answer that applies (DOR Publication 223, Bakeries, snapshot of May 25, 2026):

  1. Sold heated: taxable.
  2. Your customary practice is to physically hand the customer a utensil (napkins count): taxable, even if the customer does not end up with the napkin.
  3. A plate, bowl, glass or cup is necessary to receive the item: taxable.
  4. Utensils are not made available at all: not taxable.
  5. Four or more servings packaged as one item for a single price: not taxable.
  6. Otherwise, taxable only if your sales of certain prepared foods are more than 75% of your food sales.

The publication's examples show what that means at a counter. A "to go" donut handed over without a napkin is not taxable, while the hot coffee sold with it is. If your practice is to hand a napkin with every pastry, the pastry is taxable. A bakery selling wrapped, unheated bars and cookies by phone or website, with no utensils, does not charge tax on them. Candy, soft drinks, alcoholic beverages and dietary supplements are taxable. Decide your counter practice once, train staff on it, and write it down.

On purchases, the same publication says ingredients that are exempt food, such as flour and eggs, can be bought without tax and without an exemption certificate. Bakeries count as manufacturers, so ovens, mixers, baking pans and similar equipment used exclusively and directly in the manufacturing process may be bought without tax using an exemption certificate (Form S-211, S-211E or S-211-SST). Equipment used for anything else is taxable. This publication was in the 2022 print edition with later rate updates, so confirm current rules with DOR.

Step 8: Check Zoning and Local Rules Before You Submit Plans

The plan you submit under ATCP 75.075 must include copies of other state, county or municipal approvals, so settle zoning first. Wisconsin local governments are cities, villages, towns and counties; call the zoning office for the one that covers your address and ask whether a bakery with retail sales is allowed there, and whether a separate occupancy or building permit is needed. If you want to start in a residence, read our home-based business guide before you sign anything. Landlords and lenders set their own insurance requirements, so ask for their minimums in writing before you buy a liability policy.

Step 9: If You Hire Staff

Three Wisconsin rules arrive with the first employee:

  • Unemployment insurance: a commercial employer becomes covered with wages of $1,500 or more in a calendar quarter, or employment in 20 or more weeks in a calendar year (DWD unemployment insurance handbook, Wayback snapshot July 6, 2026).
  • Workers' compensation: coverage is required once you have three or more employees, or one or more employees paid at least $500 in gross wages in a calendar quarter for Wisconsin work (DWD workers' compensation for employers, Wayback snapshot October 19, 2026).
  • Wages: the U.S. Bureau of Labor Statistics counts 4,930 bakers (occupation 51-3011) in Wisconsin, with a median annual wage of $37,310 and a mean of $38,740 (U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (May 2025), via the BLS public API). Use that as a floor when you price your products against your labor.

Where Bakery Plans Stall

  • Ordering equipment before plan approval. The rule requires approval before construction starts, and the agency has 30 days to decide once your plan is complete. A layout change after you have installed a sink or hood costs more than a revised drawing.
  • Treating the home baker rule as a license. DATCP's page says wholesale and potentially hazardous baked goods need a license, and that the court orders cover only home producers.
  • Adding a filled product without checking the category. Cold holding adds points in Table A, and the Simple fee splits between $60 and $190 depending on whether the final product is TCS.
  • Handing napkins by habit. Under Publication 223 that turns an exempt pastry into a taxable one.
  • Counting the annual report in year one. The first report comes in the year after you form.

Expected Costs

Item Cost Where to confirm
LLC Articles of Organization (Form 502) $130 online, $170 on paper DFI fee schedule
Name reservation (optional) $15 for 120 days DFI Form 1
Retail food license (DATCP or local agent) $60 to $685 a year if you do not serve meals; $230 to $540 if you do ATCP 75.08, Table B; agents set their own fees
Pre-licensing inspection Amount in Table B; agents set their own ATCP 75.08 and your licensing office
Certified food protection manager exam Varies DATCP approved exam list
Seller's permit $20 for two years, then $10 per renewal DOR business tax registration FAQ
EIN Free IRS
LLC annual report (from year two) $25 online, $40 on paper DFI FAQ
Liability insurance Varies Your insurer, landlord and lender
Fees we could verify, year one $210 to $835 LLC filed online, license and seller's permit only

The total leaves out inspection fees, the manager exam, local agent fees, insurance, kitchen build-out and equipment, because we could not source figures for them.

After You Open

  • Renew the retail food license by June 30 each year; Table B adds a late fee if you pay after the expiration date.
  • File sales tax returns on the schedule DOR assigns when it issues your permit.
  • File the LLC or corporation annual report each year in your anniversary quarter.
  • Renew the seller's permit every two years.
  • Keep a certified food protection manager current on the 5-year exam cycle.
