How to Start a Food Truck in Wisconsin: Mobile License, Base and City Permits

If you search for a single food truck license in Wisconsin, you will not find one. The state does not issue a general business license, and most cities do not issue one either. A Wisconsin food truck is instead built from several separate approvals: a business entity filed with the Department of Financial Institutions (DFI), a seller's permit from the Department of Revenue (DOR), a mobile retail food establishment license tied to a licensed base, and whatever vending or peddler permit the city where you park requires. Each comes from a different agency, so the order you file in matters.

This guide walks through that order. It covers the known fees and marks the points you need to confirm with the agency that issues each permit. This is informational content, not legal or tax advice. If your ownership is complex, you have partners, or you are unsure how food sales are taxed, speak with a qualified attorney or CPA before you file.

What You Need Before You Start

Gather these items before you file anything:

• A business name you have checked in the DFI corporate records search
• A registered agent with a physical Wisconsin street address, since a P.O. box or mailbox service will not qualify
• An email address for that registered agent, which appears on your formation document and every annual report
• A written base agreement for either a service base or a commissary
• A truck layout covering sinks, water supply, waste tanks and refrigeration, confirmed with your licensing agency before you buy equipment
• A written menu listing the source, storage and holding method for each item
• A list of the cities and counties where you plan to operate
• Food safety training records for your staff and a question list for your health department
• A budget for filing fees, permit fees, commercial insurance and equipment

Step 1: Form Your Business Entity With DFI

Most food truck owners form a limited liability company (LLC). The Articles of Organization, Limited Liability Company (Form 502), cost $130 to file. Wisconsin business entities are filed with DFI through its Division of Corporate and Consumer Services, not with the Secretary of State.

Your name must contain limited liability company, limited company, LLC or LC, or a variation that differs only in capitalization or punctuation. Search DFI's business records before you commit to a name, but remember that a preliminary search does not guarantee availability. Availability is only final once DFI examines and files the document. If you need time to finish your setup, a name reservation holds the name for 120 days for $15.

File online through the DFI Business Entity File Online portal, or register through the Wisconsin One Stop Business Portal, which handles DFI, DOR and Department of Workforce Development registration in one pass. Online filings are in most cases accepted on receipt, and DFI's statutory limit for processing new business filings is five business days. Expedited service costs $100 on top of the filing fee.

Two recurring obligations begin as soon as the LLC exists:

• Registered agent. The LLC must always maintain a registered agent with a Wisconsin street address. The LLC cannot serve as its own agent. Changing the agent or office costs $10 online or $25 on paper.
• Annual report. The $25 LLC annual report is due each year in the calendar quarter that contains your anniversary of organization. Filing on paper adds a $15 surcharge, bringing it to $40.

Wisconsin imposes no separate LLC franchise or privilege tax. By default, a single-member LLC is disregarded and a multi-member LLC is treated as a partnership, so profits flow through to the owners' individual income tax at graduated rates from 3.50% to 7.65%. An LLC that elects corporate treatment pays the 7.9% corporate tax instead. Ask a CPA which treatment fits your truck.

Step 2: Register Your Seller's Permit With the Department of Revenue

Any seller of taxable products or services in Wisconsin must hold a seller's permit. You obtain it through the Department of Revenue's Business Tax Registration. Start from the DOR new business page or go directly to the Business Tax Registration system. The initial registration costs $20 for a two-year period, and each renewal costs $10 for two years.

The state sales tax rate is 5%. Food you sell prepared from your truck is commonly taxable, but treatment depends on what you sell and how you sell it. Confirm each menu category with DOR before you open, and ask whether any local tax applies in the areas where you will operate.

Step 3: Secure a Licensed Base

A mobile food license in Wisconsin is tied to a licensed base. The base is where the truck gets water, dumps waste, restocks and stores food, and where food is prepared or the unit is serviced. The two common types are a service base, where the truck is cleaned, serviced and supplied, and a commissary, where food is prepared and stored. Confirm with your licensing agency which base type it will accept and how often the truck must return to it.

Sign the base agreement before you apply. Your application will ask for the base address, and an unsigned lease or a verbal promise can delay your file. Put the agreement in writing and confirm the hours, cleaning access, water and waste arrangements, and storage space.

Step 4: Apply for the Mobile Retail Food Establishment License

A license from the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) suits a truck that works in several counties. Local health departments may act as DATCP's agent for inspections, and they may still inspect your unit and charge their own fees. Expect the application to ask for your entity details, base information, vehicle plans, menu and food handling procedures.

Do not budget from a fee or processing time you find elsewhere. Confirm the current form, fee, processing time, plan review requirements and inspection schedule with DATCP's food safety program or your local health department before you buy or retrofit the truck.

Step 5: Contact the Local Health Department

Before you buy the truck, call the health department for every county and city where you plan to operate. Ask these questions:

1. Is this jurisdiction a DATCP agent, and who inspects mobile units here?
2. Does the department charge its own license or inspection fee?
3. Will the department accept my base and my truck plan?
4. What food safety certification or training does the department expect from my manager?
5. Do I need a separate inspection each time I move into a new county?

Get the answers in writing or by email. A written answer protects you if the staff who approved your plan leaves or the answer changes later.

Step 6: Secure City Vending and Peddler Permits

Wisconsin has no statewide food truck preemption, so cities add their own vending and peddler rules on top of the state license. Confirm the rules for each city on your route. As of 2026, these are the main city requirements:

• Milwaukee. The city requires a food peddler license or permit, valid for one year. Apply through the City Clerk License Division, which sets the fee. Confirm the current fee and application steps before you apply, since a Milwaukee food truck permit is a separate approval from your state license.
• Green Bay. The mobile food vendor license expires December 31 each year, so set your renewal reminder for the fourth quarter. Confirm the fee and application with the City of Green Bay.
• Madison. Madison runs a street vending program. Ask the City of Madison how the program handles locations, reservations and fees before you plan a route. Confirm each detail before you build a schedule around Madison stops.

If you plan a Wisconsin food truck route that crosses city lines, treat each city as its own application. A permit in one city does not carry over to the next.

Step 7: Plan Parking and Event Locations

A permit does not give you the right to park anywhere. Check each city's rules on where a food truck may stop, how long it may stay, and whether private property requires written permission from the owner. Private lots, event grounds and festivals often have their own vendor contracts and insurance requirements. Get the owner's permission in writing before you commit to a site.

Step 8: Set Up Insurance and Recordkeeping

Talk with an insurance agent about commercial auto and general liability coverage before you operate. Event organizers and some property owners ask for a certificate of insurance, and you cannot supply one without a policy. Keep copies of your entity filing, seller's permit, base agreement, health license, city permits and inspection reports in one folder, and set calendar reminders for every renewal.

Common Mistakes to Avoid

• Buying the truck first. Equipment that does not match the health department's plan can force a rebuild. Get the plan reviewed before you spend the money.
• Using a P.O. box for the registered agent. DFI requires a physical Wisconsin street address for the registered office.
• Assuming one license covers every city. A state or county license does not replace a city vending or peddler permit.
• Signing a base agreement without checking it. Confirm that the base satisfies your licensing agency before you pay a deposit.
• Forgetting the annual report. The $25 report is due every year. Put the due quarter on your calendar the day you form the LLC.
• Overlooking the trade name option. If you trade under a name other than your LLC name, you can register it as a trade name with DFI for $15 before you print signage. Registration is optional.

Tips for a Smoother Launch

• Call DATCP and your target health departments before you order equipment. One conversation can prevent a costly rebuild.
• Choose your base early, since it shapes your route, your storage and your inspections.
• Keep one calendar for the annual report, seller's permit renewal, city renewals and health license renewals.
• Start with routes where you have confirmed permits, then add new cities one at a time.

What Results to Expect

A complete setup can put you in a position to open on schedule, with your entity, tax registration, base and permits in order. The steps above are designed to help you operate within the rules and avoid stop-work problems. No permit guarantees sales, each agency sets its own review timeline, and requirements can change. Expect the first months to include inspections, follow-up questions and adjustments to your plan.
