How to Start a Catering Business in Wisconsin

Last verified: November 10, 2026

A Wisconsin caterer is licensed as a retail food establishment serving meals. DATCP's page for retail food establishments serving meals and catering says that license is required if you prepare, serve or sell meals to the public, and that it can be issued by the Department of Agriculture, Trade and Consumer Protection (DATCP) or by one of its agent health departments. The license belongs to your kitchen, not to the event venues you serve, and that one fact shapes the order of everything below.

Our advice: settle the kitchen and the agency that will license it before you spend on anything else. The LLC, the seller's permit and the insurance quote are quick to adjust; a kitchen that cannot pass plan review is not. This guide covers a caterer who cooks in a kitchen and serves at events. If you serve from a dining room, read how to open a restaurant in Wisconsin; if you sell from a truck or trailer, read how to start a food truck in Wisconsin.

What You Need Before You Start

Gather these before your first call to a licensing office, because the plan application asks for most of them:

  • The address of the kitchen you will cook in, and the name of the agency that licenses that address (Step 1).
  • A menu that notes which foods you will hold hot or cold, cook from raw meat, poultry, eggs or seafood, and cool after cooking. These decide your license category (Step 3).
  • Equipment layout plans, an equipment schedule, descriptions of your food processing operations, and copies of any other state, county or municipal approvals, which are the items ATCP 75.075 lists for plan approval.
  • A person who will hold a certified food protection manager credential (Step 4).
  • A business name you have searched in the DFI corporate records search and, for an LLC, a registered agent with a physical Wisconsin street address and an email address.

How Wisconsin Licenses a Caterer

The rule that defines the term is ATCP 75.04: catering means contracting to prepare and serve a defined amount of food at a specific location other than the licensed retail food establishment, for a defined set of guests at a wedding or similar event or for an organized group. Selling individual meals directly to consumers is not catering under that definition.

Three provisions in ATCP 75.063 and ATCP 75.06 decide how you plan:

  • The serving location needs no license of its own. The rule exempts the location where a caterer serves food that was prepared at the caterer's licensed retail food establishment. The license attaches to the kitchen.
  • Each establishment needs its own license. A license cannot be transferred between persons or establishments. Our reasoning: if you rent time in a shared kitchen, ask the agency in writing whose name the license goes under before you sign anything.
  • Contract cooks and personal chefs are exempt only in narrow cases. A personal chef cooks in the client's own home kitchen, for the client, the client's family or non-paying guests. A contract cook cooks on site with food the contractor provides. Both lose the exemption if they prepare or store food in bulk for use at multiple sites or for the public, or if they transport any part of a meal from one location to another. If you cook in bulk and drive it to events, plan on a license.

One thing we could not confirm: whether a residential kitchen can be licensed for catering. The definitions, licensing, fee and plan review sections we read do not address it, and we have no source that says either way. The pre-licensing inspection and plan approval apply to any establishment, so ask your agency in writing before you build a plan around a home kitchen. If you only plan to sell baked goods made at home, read Wisconsin cottage food law instead.

Step-by-Step: Starting a Wisconsin Catering Business

Step 1: Find Out Who Will License Your Kitchen

DATCP says to start by calling its licensing specialists at 608-224-4923 or emailing [email protected]; they will tell you whether DATCP or a local agent licenses your address. Agents set their own license fees, so ask yours for its fee schedule (ATCP 75.06). Local agents we found on official sites include the Waukesha County Environmental Health unit, St. Croix County Public Health, City of Racine Public Health, the City of Appleton Health Department and the Wauwatosa Health Department. That list is examples, not a complete map of the state.

Step 2: Get Plan Approval Before You Build

Under ATCP 75.075, an applicant for a new or extensively remodeled establishment must obtain plan approval from the department or its agent before construction begins. The application takes equipment layout plans, an equipment schedule, descriptions of food processing operations, menus, copies of other approvals, and plans drawn to scale. Once your information is complete, the agency has 30 days to approve or deny the plan and must give written reasons for a denial.

Our advice: get the approval before you sign a lease, not after. A lease on a space that fails plan review costs you rent while you redesign. Before a license is issued to a new establishment, the agency also does a pre-licensing inspection and you pay the pre-licensing fee in the table below (ATCP 75.06 and 75.08).

Step 3: Work Out Your License Category and Fee

DATCP assigns a category by adding points from Table A in ATCP 75.08: simple at 2.5 points or less, moderate above 2.5, and complex at 4.5 points or more. The rule's moderate band is written as "not greater than 4.5" and the complex band as "4.5 or more", so a score of exactly 4.5 is ambiguous; ask the agency how it scores you. Among the factors that add one point each:

  • A catering operation, or processing, packaging or holding customer preordered meals.
  • Cold holding, hot holding or reheating of time and temperature control foods.
  • Cooling cooked or reheated time and temperature control foods.
  • Handling raw poultry, meat, eggs or seafood.
  • Food that needs chopping, dicing, mixing, slicing, blanching, boiling, cooking, packaging or assembly to be served.
  • One or more additional areas where food is prepared.
  • Serving a highly susceptible population such as a nursing home or day care.
  • Seating more than 75 customers, or running a drive-through window.

Our arithmetic, not an agency decision: a caterer who cooks from raw meat, holds food hot and cold, cools leftovers and runs events scores catering (1) plus holding (1) plus cooling (1) plus raw meat (1) plus processing (1), which is 5 points and the complex category. A caterer who only assembles and holds cold food could land at 3 points, in moderate. The agency does the scoring, so bring your menu.

Category (serving meals)Annual license feePre-licensing inspection feeReinspection fee
Prepackaged$105$130$98
Simple$230$320$240
Moderate$330$470$353
Complex$540$770$578

The annual fees match the table on DATCP's own catering page (Wayback snapshot June 10, 2026); the inspection and reinspection fees are from ATCP 75.08, Table B. If your agency licenses you instead of DATCP, use its fee schedule. Licenses issued by DATCP expire June 30, and one first issued between April 1 and June 30 runs to June 30 of the following year. After you submit a complete application, the department or its agent has 30 business days to grant or deny it. Operating without a license carries a $749 fee in Table B, and the rule's note adds a fine of $100 to $1,000 under s. 97.72, Stats.

For a single special event, ATCP 75.06 describes a transient retail food establishment license valid for up to 14 days; Table B lists it at $75 for non-TCS food and $170 for TCS food. It is tied to one event, so it is not a substitute for a year-round caterer license. Ask the agency whether your event qualifies.

Step 4: Name Your Certified Food Protection Manager

DATCP's food manager requirements page (Wayback snapshot August 13, 2026) says most licensed food establishments must have at least one manager or operator certified in food protection practices. The exemptions it lists are prepackaged-only retail food establishments, those handling only fresh fruits or produce, transient events and micro markets; a caterer's kitchen is not on that list. The operator or manager of a new establishment must hold the credential within the first 90 days after opening. The exam certificate, taken within the past 5 years, must be posted where inspectors can see it, and managers retake an approved exam every 5 years. Small operators with 5 or fewer food handlers can renew through an approved refresher course within 90 days after expiry.

DATCP lists the accepted exams through the American National Standards Institute and does not state an exam price, so we state none. Do not treat the 90 days as slack: ATCP 75.08 charges a $150 fee for operating without a certified food manager. Your agency may apply its own timing, so confirm it when you call in Step 1.

Step 5: Choose a Business Structure and File With DFI

A sole proprietor needs no state filing to operate under their own name. Wisconsin does not require a sole proprietor to register a business name, and a voluntary tradename registration with DFI costs $15 and lasts 10 years (see the Wisconsin SBDC business licenses and registrations FAQ and DFI trademark general information). Our trade name guide covers that choice.

Many caterers form an LLC to keep business debts separate from personal assets; ask an attorney whether that fits your situation, because an LLC does not replace insurance. Wisconsin business entities file with the Department of Financial Institutions (DFI), not a Secretary of State. The DFI fee schedule (Wayback snapshot October 19, 2026) lists Articles of Organization (Form 502) at $130 online or $170 on paper, with optional expedited service for $100 more. A name reservation costs $15 for 120 days, and the annual report costs $25 online or $40 on paper, first due in the year after you form. File through the DFI online filing system. Nothing on DFI's fee table promises a turnaround, so we state none. For the full filing see the Wisconsin LLC guide, or compare filing it yourself with using a formation service in our Wisconsin LLC services comparison.

After the entity exists, get an EIN from the IRS. The IRS EIN page says you never have to pay a fee for an EIN, so skip any site that charges one.

Step 6: Register With the Department of Revenue

Register through the DOR business tax registration system or the Wisconsin One Stop Business Portal; the portal handles only LLCs, business corporations and statutory close corporations. The seller's permit fee is $20 and covers two years, with renewal at $10 every two years (DOR business tax registration FAQ, Wayback snapshot October 9, 2026). DOR asks you to apply at least three weeks before you open, and each location needs its own permit. Our seller's permit guide has the details.

The state sales tax rate is 5%. Most counties add a county tax, usually 0.5%; Milwaukee County is 0.9%, the City of Milwaukee adds 2%, and Waukesha and Winnebago counties have none (DOR sales and use tax rates, Wayback snapshot October 26, 2026). We did not read DOR's guidance on how catering charges, delivery fees and gratuities are taxed, so ask DOR how it treats each charge on your quotes before you print them. See Wisconsin sales tax by county for the local layer.

Step 7: Price Insurance, Staff and Taxes

We found no insurance minimum in ATCP 75.06 or ATCP 75.075, the licensing and plan review sections we read, so we state none here. A venue contract or a lender may impose one, so ask each client venue what it requires before you quote, and get a written insurance quote that covers food served away from your kitchen. Our business insurance guide covers the general picture.

Event staff change your obligations. Wisconsin's minimum wage is $7.25 an hour (DWD, read November 10, 2026). Workers' compensation coverage is required once you have three or more employees, or one or more employees paid $500 or more in a calendar quarter for Wisconsin work (DWD workers compensation for employers). A commercial employer becomes covered for unemployment insurance with wages of $1,500 or more in a quarter or employment in 20 or more weeks in a calendar year (DWD employer handbook, Wayback snapshot July 6, 2026); a new employer paying under $500,000 in payroll is assigned 3.05% on a $14,000 wage base for 2026 and 2027 (DWD unemployment tax rates). See our employer requirements guide.

For income tax, Wisconsin's individual rates for tax year 2026 run from 3.5% to 7.65% by bracket (DOR 2026 Form 1-ES instructions, Wayback snapshot August 17, 2026). An LLC that elects to be taxed as a corporation pays the 7.9% corporate rate (DOR corporation franchise and income tax FAQ, Wayback snapshot October 11, 2026). Ask a CPA which treatment fits an event business with uneven months.

Step 8: Decide on Alcohol Early

Alcohol licenses are separate from the food license, and retail licenses come from the municipality, not DATCP (DOR alcohol beverage licenses FAQ). If you want to serve drinks at events, ask the clerk in each place you plan to serve whether a license is needed for your arrangement, and read our Wisconsin liquor license guide.

Common Mistakes to Avoid

  • Licensing the venue instead of the kitchen. The rule exempts the serving location when the food came from your licensed establishment. Spend the effort on the kitchen.
  • Guessing the category. The difference between moderate and complex is $210 a year in license fees and $300 in pre-licensing inspection fees, so score your menu before you budget.
  • Calling yourself a personal chef. The exemption ends when you cook in bulk or transport meals between locations.
  • Treating the food manager as a later task. The 90-day clock starts when you open, and ATCP 75.08 charges $150 for operating without one.
  • Opening before the license is issued. The fee for operating without a license is $749, plus a possible fine.
  • Using a P.O. box as the registered office. DFI's Form 502 requires an actual street address, not solely a P.O. box, mailbox service or answering service.

When This Guide Is Not Enough

We could not read the Wisconsin Food Code text in the ATCP 75 appendix, local zoning for any specific address, or any agent's own fee schedule, so confirm those with the agency in Step 1. Talk to an attorney about leases, venue contracts and liability, and to a CPA about entity taxes. The Wisconsin Small Business Development Center offers no-cost, confidential consulting on business plans and pricing.
