The Brown County, Wisconsin sales tax rate is 5.5%, made up of the 5% Wisconsin state sales tax plus a 0.5% county sales and use tax. That combined rate applies to most retail purchases delivered or received in the county, and it has been in effect since January 2018. No city, stadium, or premier resort area tax layers on top of it anywhere in Brown County.1Wisconsin Department of Revenue. DOR Premier Resort Area Tax
How the 5.5% Breaks Down
Wisconsin imposes a 5% statewide sales tax on retailers who sell taxable goods, digital products, or services in the state.2Wisconsin Department of Revenue. DOR Tax Rates Brown County adds its own 0.5% county sales and use tax under Wisconsin Statutes Section 77.70, which requires the county to adopt the tax by ordinance and file a certified copy with the Secretary of Revenue at least 120 days before it takes effect.3Wisconsin State Legislature. Wisconsin Statutes 77.70 – Adoption by County Ordinance Seventy of Wisconsin’s 72 counties have adopted the same 0.5% local rate, so the 5.5% total is the norm across most of the state.
What’s Taxable at 5.5%
Goods and Enumerated Services
The combined rate applies to most tangible personal property purchased or delivered in the county: clothing, electronics, furniture, motor vehicles, and similar items.4Wisconsin Department of Revenue. What Is Taxable Services are a narrower list. Wisconsin taxes only those services specifically named in statute, including lodging, admissions to entertainment or sporting events, telecommunications, laundry and dry cleaning, photography, parking, towing, and repair or maintenance of tangible personal property.5Wisconsin State Legislature. Wisconsin Statutes 77.52 If a service isn’t on the enumerated list, it generally isn’t taxable.
Digital Products
Specified digital goods — digital audio, digital video, and digital books — are taxable at the full 5.5% whether you buy permanent access or a subscription. Wisconsin also taxes a second tier of digital goods that includes electronic greeting cards, finished artwork, periodicals, video games, and digital newspapers. Prewritten computer software accessed online is generally taxable. One exception matters: if you’re paying a provider to process your data using their software and they control the processing, that counts as a nontaxable service rather than a taxable digital good.6Wisconsin Department of Revenue. Wisconsin Sales and Use Tax Information – Publication 240
Shipping and Delivery
Delivery charges follow the taxability of what’s being shipped. If the product is taxable, the full charge including delivery is taxable, no matter who carries it. If the product is exempt, so is the delivery charge. For a shipment that mixes taxable and exempt items, the seller must allocate the shipping charge on the invoice. Skip the allocation and the entire delivery charge becomes taxable.7Wisconsin State Legislature. Wisconsin Administrative Code Tax 11.94 – Delivery Charges
What’s Exempt
Groceries
Most grocery food and food ingredients are exempt from both the state and county portions. That covers items bought at a grocery store for home consumption, including prepackaged ice cream and frozen treats. Four categories stay fully taxable: candy, dietary supplements, prepared food, and soft drinks. Prepared food includes anything sold heated, anything sold with eating utensils provided by the seller, and food where the seller mixes two or more ingredients to sell as a single item. Mandatory service charges or tips on prepared food are part of the taxable sales price.8Wisconsin State Legislature. Wisconsin Administrative Code Tax 11.87 – Food and Food Ingredients
Medical Items
Prosthetic devices worn on or placed in the body are exempt, along with their repair and replacement parts and accessories. Durable medical equipment used in a person’s home is exempt when it is primarily used for a medical purpose and isn’t useful to someone who isn’t ill or injured.9Wisconsin State Legislature. Wisconsin Administrative Code Tax 11.45 – Medical Items Prescription medications are separately exempt. Over-the-counter drugs without a prescription are generally taxable.
Resale Purchases
Businesses buying inventory to resell don’t owe tax on those purchases, but they need an exemption certificate on file. Wisconsin uses Form S-211 or the Streamlined version, Form S-211-SST. For resale, the certificate has to include the buyer’s name, address, and signature, a description of the business, and the buyer’s seller’s permit number. Wholesalers who sell only to other resellers can write “wholesale only” in the permit field, and out-of-state sellers who make no Wisconsin retail sales can substitute their out-of-state permit information.10Wisconsin State Legislature. Wisconsin Administrative Code Tax 11.14 – Exemption Certificates
Which County’s Rate Applies
Wisconsin uses destination-based sourcing under the Streamlined Sales and Use Tax Agreement. The rate is set by where the buyer receives the product or where the service is performed, not where the seller sits. A retailer in Outagamie County shipping to a customer in Brown County charges the Brown County 0.5%. Two Wisconsin counties still have no local tax, so a delivery address can change what you owe.
Use Tax on Out-of-State Purchases
Buy something taxable from a seller that doesn’t collect Wisconsin tax, and you owe use tax yourself at the same 5.5% rate. The use tax keeps out-of-state purchases from undercutting local retailers on price. Individuals report it on their Wisconsin income tax return (Form 1 or 1NPR), which has a line for internet and mail-order purchases, or they file a quarterly Consumer Use Tax Return on Form UT-5.11Wisconsin Department of Revenue. Wisconsin Use Tax – Fact Sheet 2104 Businesses already registered for Wisconsin sales tax report use tax on their regular return. The Department of Revenue warns that unpaid use tax can trigger late filing fees, interest, penalties up to 50% of the tax owed, and collection actions.
If You’re Selling: Registration and Filing
Any retailer making taxable sales in Wisconsin needs a seller’s permit before collecting tax. The registration fee is $20 and covers the permit regardless of how many locations you run. Online registration is the standard route; the paper BTR-101 form is still accepted at Department of Revenue offices.12Wisconsin Department of Revenue. DOR Business Tax Registration The application asks for the legal business name, federal employer identification number, and estimated monthly sales volume.13Wisconsin Department of Revenue. BTR-101 Application for Wisconsin Business Tax Registration
The Department assigns a filing frequency based on how much tax you collect:14Wisconsin Department of Revenue. Annual Filing Frequency Scan
- Early monthly: $3,601 or more per quarter in tax remittances
- Monthly: $1,201 to $3,600 per quarter
- Quarterly: $601 to $1,200 per quarter
- Annual: $600 per year or less
Returns go through the My Tax Account portal. The system handles both state and county portions in one filing; there is no separate return to Brown County.
Remote Sellers
Out-of-state sellers must collect and remit Wisconsin sales tax once their gross sales into the state exceed $100,000 in the current or previous calendar year.15Wisconsin Department of Revenue. DOR Remote Sellers – Wayfair Decision Wisconsin uses a revenue-only test with no separate transaction count. Once you cross the threshold, you collect the full combined rate, Brown County’s 0.5% included, on everything you deliver into the county.
Penalties and Interest
Wisconsin’s penalty structure escalates quickly:16Wisconsin State Legislature. Wisconsin Statutes 77.60 – Interest and Penalties
- Late filing fee: $20 per delinquent return.
- Failure to file: 5% of the unpaid tax for the first month, plus 5% for each additional month or partial month, capped at 25%.
- Incorrect return: 25% of the entire tax finally determined.
- Fraud or intent to evade: 50% of the tax owed, on top of interest and other penalties.
- Fraudulent refund claim: 100% of the excess amount claimed.
Interest runs at 12% per year from the return’s due date until the tax is paid. Once a balance goes delinquent, the rate jumps to 1.5% per month, roughly 18% annualized, with no cap. A small business that misses a couple of quarterly filings can face combined penalties and interest larger than the original tax. Filing on time with a short payment beats not filing, because the failure-to-file penalty stacks on top of interest.
