The Wisconsin sales tax is 5% at the state level, but almost no one pays only 5%. Seventy of the state’s 72 counties add 0.5%, Milwaukee stacks a county and city tax that brings the combined rate inside the city to 7.9%, and a handful of resort communities tack on their own charge. What follows is what you owe as a buyer, what’s exempt, and what you need to do if you sell.
What Rate You Actually Pay
The state rate of 5% applies to retailers who sell, lease, or rent taxable goods and services.1Wisconsin Department of Revenue. Tax Rates On top of that:
- Seventy of 72 counties charge an additional 0.5% county sales tax, making 5.5% the typical combined rate across most of Wisconsin.1Wisconsin Department of Revenue. Tax Rates
- Milwaukee County’s rate rose to 0.9% on January 1, 2024. The City of Milwaukee adds another 2.0%, so purchases within city limits are taxed at a combined 7.9%.2Wisconsin Department of Revenue. City of Milwaukee Sales and Use Taxes
- Certain tourism-focused communities impose a premier resort area tax between 0.5% and 1.25% on qualifying retail and hospitality sales. Wisconsin Dells and Lake Delton sit at the top of that range.3Wisconsin Department of Revenue. Premier Resort Area Tax
The rate that applies to a given purchase is the one for the location where the sale is sourced, which for most in-store sales is the store itself and for most shipped goods is the delivery address.
What Wisconsin Taxes
Physical Goods
The 5% state tax applies broadly to sales of tangible personal property: clothing, furniture, electronics, vehicles, building materials, and most other items you buy at retail. Rentals and leases of tangible goods are taxable too. If a physical item is sold at retail and no exemption covers it, assume it’s taxed.
Services
Wisconsin taxes more services than people expect, though not all. The taxable list includes lodging, telecommunications, admissions to amusement and entertainment events, parking, laundry and dry cleaning, photography, towing, and most repair and maintenance work on tangible personal property. One distinction worth knowing: repair work on real property improvements, like fixing a furnace that’s permanently installed, is generally not taxable, while repairing a portable appliance is.
Digital Products
Downloaded and streamed digital products are taxed at the same 5% state rate as their physical equivalents. Wisconsin taxes “specified digital goods,” which include digital audio works (music, audiobooks, podcasts), digital audiovisual works (movies, TV shows, streaming video), and digital books. The tax applies whether your access is permanent or temporary, so a one-time movie rental and a purchased album are both taxable.4Wisconsin Department of Revenue. Publication 240 – Digital Goods Digital codes used to obtain these products are treated the same as the goods themselves.
Common Exemptions
A few broad categories of purchases escape the tax entirely.
- Food and food ingredients bought for home consumption are exempt. Candy, soft drinks, dietary supplements, and prepared food stay taxable. “Prepared food” generally means food sold heated, combined by the seller, or sold with eating utensils provided. A frozen pizza from the grocery store is exempt; a slice from a restaurant is not.5Wisconsin State Legislature. Wisconsin Code 77.54 – General Exemptions
- Prescription drugs dispensed by a pharmacist for a human being are exempt, along with insulin for diabetes treatment and drugs furnished directly by licensed physicians, surgeons, dentists, and hospitals for patient treatment.5Wisconsin State Legislature. Wisconsin Code 77.54 – General Exemptions
- Durable medical equipment for home use, mobility-enhancing equipment, and prosthetic devices (plus their accessories) are exempt when used by a human being.5Wisconsin State Legislature. Wisconsin Code 77.54 – General Exemptions
- Machines and processing equipment used exclusively and directly by a manufacturer to produce tangible goods are exempt. Storage, R&D, delivery, and building maintenance equipment do not qualify.6Wisconsin Department of Revenue. Publication 203 – Sales and Use Tax Information for Manufacturers
- Goods bought solely for resale are exempt if the buyer gives the seller a properly completed exemption certificate.
To claim any of these at the register, the buyer provides the seller with a completed Wisconsin Sales and Use Tax Exemption Certificate, Form S-211 (or the electronic S-211E).7Wisconsin Department of Revenue. Electronic Wisconsin Sales and Use Tax Exemption Certificate The form requires the buyer’s name, address, tax permit number, and the specific exemption reason. If a seller accepts an incomplete certificate and the Department of Revenue later audits the transaction, the seller can be held liable for the uncollected tax.8Wisconsin Department of Revenue. Wisconsin Sales and Use Tax Exemption Certificate – Form S-211 Misusing an exemption certificate carries a $250 penalty per invoice.9Wisconsin State Legislature. Wisconsin Code 77.60 – Interest and Penalties
Use Tax: When No One Charged You
Wisconsin’s use tax covers purchases where no sales tax was collected at the time of sale. The most common trigger is buying something online from a retailer that didn’t charge Wisconsin tax, then storing or using the item in Wisconsin. The use tax rate matches the sales tax rate that would have applied at your location, so the combined state and county (and city, if applicable) rate is what you owe.
Most individuals report use tax on their Wisconsin income tax return. The return has a line for it, and the Department of Revenue publishes a lookup table based on income to simplify the calculation for smaller purchases. For a large untaxed purchase, calculate the actual tax rather than using the table. Businesses that regularly make untaxed purchases can register for a use tax certificate and file on the same schedule as their sales tax returns.
If You Sell in Wisconsin
In-State Sellers
Any business selling taxable goods or services in Wisconsin needs a seller’s permit before it starts collecting tax. First-time applicants typically use the online Business Tax Registration (BTR) application, though a paper Form BTR-101 is accepted at any DOR office or by fax. The initial registration fee is $20 and covers all locations; renewal is $10, and the DOR sends a BTR Certificate with a new expiration date rather than issuing a fresh permit.10Wisconsin Department of Revenue. Business Tax Registration
Remote Sellers
Out-of-state sellers must collect and remit Wisconsin tax once their gross sales into Wisconsin exceed $100,000 in the current or previous calendar year.11Wisconsin Department of Revenue. Remote Sellers Common Questions There’s no transaction-count threshold; it’s purely a dollar test. The obligation starts once you cross the line, not retroactively to the start of the year. Sellers below the threshold qualify for a small-seller exception, though they may voluntarily register.
Marketplace Sellers
Since January 1, 2020, marketplace providers like Amazon, Etsy, and eBay collect and remit Wisconsin tax on third-party sales they facilitate.12Wisconsin Department of Revenue. Marketplace Providers and Sellers If all your sales go through such a platform, you don’t collect separately on those transactions. If you also sell through your own website, at craft fairs, or from a storefront, you remain responsible for the tax on those non-marketplace sales.
Filing, Payments, and What Happens if You’re Late
Once registered, you file sales and use tax returns through My Tax Account (MTA), the DOR’s online portal. The department assigns your filing frequency, monthly, quarterly, or annually, based on sales volume. Returns are due by the last day of the month following the reporting period. Businesses designated “early monthly” filers must file by the 20th of the following month.13Wisconsin Department of Revenue. Sales and Use Tax – Common Questions A return is required for every assigned period, even one with no tax due.
Wisconsin’s penalty structure compounds quickly:
- A $20 flat late filing fee applies to any delinquent return.9Wisconsin State Legislature. Wisconsin Code 77.60 – Interest and Penalties
- Unpaid tax accrues interest at 1.5% per month, or 18% annualized.9Wisconsin State Legislature. Wisconsin Code 77.60 – Interest and Penalties
- Failing to file at all adds 5% of the tax due for each month the return is late, capped at 25%.9Wisconsin State Legislature. Wisconsin Code 77.60 – Interest and Penalties
- Filing an inaccurate return triggers a 25% penalty on the entire tax ultimately determined to be due.
- Intentionally filing a false return or evading the tax results in a 50% penalty on the tax owed, on top of interest and other penalties.9Wisconsin State Legislature. Wisconsin Code 77.60 – Interest and Penalties
If you fail to file, the department can also estimate your liability and add a 25% penalty on that estimate. A business that simply forgets to file for a few months can owe the $20 fee, 1.5% monthly interest, and a failure-to-file penalty climbing toward 25% of the balance. Filing on time, even a zero-dollar return, avoids all of it.
