Credit card processing and merchant services in Green Bay, WI
Taxable sales in Green Bay carry 5.5%: Wisconsin's 5% plus the Brown County tax that began January 1, 2018. For more than two years before that, Brown County had no local sales tax at all.
Green Bay's sales tax rate has changed twice in about a decade, both times because of a Brown County tax. Until September 30, 2015, taxable sales in the county carried a 0.5% football stadium district tax on top of Wisconsin's 5%. The Wisconsin Department of Revenue announced that the district tax would end then, and from October 1, 2015 Brown County sales carried the 5% state rate alone. On January 1, 2018, the county's own 0.5% sales and use tax took effect, and the total has been 5.5% since.
Today that means one setting for a Green Bay store: 5.5% on taxable sales, or $2.20 on a $40 sale. There's no city tax to add, because the City of Milwaukee is the only Wisconsin municipality with one. Inside Milwaukee's city limits the same $40 sale carries $3.16 at 7.9%, so a business selling in both cities can't share a rate. Our Milwaukee page explains that city's setup.
Wisconsin leaves surcharges to the card networks: no state statute, a 3% cap on Visa, 4% on Mastercard, your cost as the ceiling, and no surcharge on debit. What the state does protect is the cash discount. Under Wis. Stat. 422.422, no card issuer may stop a merchant, by contract or otherwise, from giving a discount for payment by cash or check. If you'd rather reward cash than add a card fee, state law backs you, and our cash discount program guide explains how that pricing works. The Wisconsin page has both rules and their sources.
Green Bay had 106,675 residents in the Census Bureau's July 1, 2025 estimate, 0.6% below its April 2020 base.

Common questions
What is the sales tax rate in Green Bay?
5.5% on taxable sales: Wisconsin's 5% state rate plus Brown County's 0.5% county tax, which took effect January 1, 2018. Green Bay has no city sales tax; the City of Milwaukee is the only Wisconsin municipality that charges one.
Is Brown County's 0.5% tax the old stadium tax?
No. The 0.5% football stadium district tax ended on September 30, 2015, and from October 1, 2015 Brown County sales carried only the 5% state rate. The current 0.5% is the county's own sales and use tax, in effect since January 1, 2018. The total matches the pre-2015 rate, but it's a different tax.
Should a Green Bay business surcharge or give a cash discount?
Both are legal in Wisconsin. A surcharge follows card network rules: credit cards only, capped at your cost and at 3% on Visa or 4% on Mastercard, disclosed before the sale. A cash discount is protected by Wis. Stat. 422.422, and the card price then applies to every card, debit included. Our guide to dual pricing vs. surcharging compares the two.
How can a Green Bay food truck take cards?
With mobile payments: tap to pay on a phone or a mobile card reader. Taxable sales in Brown County carry 5.5%. If the truck also works events in other counties, check each county's rate before you go: the Department of Revenue says seventy counties have adopted a 0.5% county tax, but Milwaukee County's is 0.9%.
