Oshkosh, Wisconsin Sales Tax Rate

Manufacturing (Oshkosh Corp), education (UW-Oshkosh), and tourism (EAA AirVenture)

The combined sales tax rate in Oshkosh is 5.000%, composed of the Wisconsin state rate of 5.000% plus a local portion of 0.000%. On a receipt, that stacks up as: State 5% — no county add-on in Winnebago = 5%.

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in Oshkosh: tax is $7.50 ($150.00 × 0.05000), total is $157.50.

Visitor spending around EAA AirVenture Museum and Oshkosh Corporation flows straight through the 5.000% combined rate — on dining, retail, entertainment, and ground transportation alike. For Oshkosh operators, that makes visitor volume a direct driver of sales tax remittance, and it makes getting the rate right on every channel (POS, online booking, mobile ordering) a compliance issue, not a rounding detail.

Major draws behind Oshkosh's visitor volume: EAA AirVenture Museum, Oshkosh Corporation, UW-Oshkosh, Menominee Park.

A room night in Oshkosh usually carries more than the 5.000% combined sales tax: most Wisconsin lodging markets layer a separate occupancy or lodging tax on top. The exact stack is set locally — confirm the current schedule with Winnebago County before publishing rates.

Three charges typically sit on top of the 5.000%: an occupancy tax on the room, a short-term-rental tax that many cities now make the platform collect rather than the host, and any convention-centre or tourism-district assessment covering EAA AirVenture Museum. None of the three is set by Wisconsin — which is why a rate that is correct in Oshkosh can be wrong one town over. How each is levied and who remits it is worked through in the short-term rental and lodging tax guide rather than restated here.

Admissions taxability is one of the sharpest state-by-state splits: many states tax tickets at the full combined rate — which in Oshkosh means 5.000% on top of face value — while others do not tax admissions at all. Before pricing tickets to EAA AirVenture Museum, verify Wisconsin's admissions rules.

• Ticket taxability depends on Wisconsin's admissions rules — never assume the general rate applies
• Bundled packages (ticket + meal + merchandise) may require allocation
• Non-profit venues may qualify for exemptions — verify with Winnebago County

Business travel into Oshkosh generates taxable spend well beyond the hotel bill. What visiting teams and their finance departments should expect:

• Food, beverage and AV hire billed by the venue carry the full 5.000%, so a five-figure catering line arrives with $500 of tax on every $10,000 of it.
• Booth and exhibit materials shipped in tax-free from another state do not escape — they land as Wisconsin use tax at the same rate, self-assessed by whoever brought them in.
• Per diems and receipts diverge here: a meal per diem is not a taxable supply, but an actual restaurant receipt from Oshkosh already includes the tax, and expensing both ways in one trip is how the reconciliation breaks.

Retailers working the visitor trade near EAA AirVenture Museum and Oshkosh Corporation should implement:

The one that actually bites is address-level rate verification. A visitor-trade business sits close to a municipal boundary far more often than a suburban one does, and Oshkosh's 5.000% stops applying at a line that is not always visible from the street — the address-level rate guide covers how to resolve it. Everything else here is configuration: tourism-district surcharges set in the POS, and receipts that show the state and local components separately so a visitor claiming a refund can read what they paid.

Since South Dakota v. Wayfair, a seller with no premises, staff or stock anywhere near Oshkosh can still be required to register in Wisconsin and charge 5.000% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Oshkosh and its neighbours have to be priced separately. The registration mechanics and the trailing-twelve-month counting rules are in the economic nexus guide.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.

Three obligations follow the 5.000% rate around Oshkosh: untaxed out-of-state purchases delivered here owe matching use tax — $50.00 on a $1,000 order — self-assessed to Winnebago County; sellers with physical presence or economic nexus must register before collecting; and wholesale sales need a valid resale certificate on file at transaction time. Filing mechanics, exemption certificates, and audit preparation are covered in the Wisconsin sales tax guide.

Oshkosh carries significant industrial activity. Manufacturing equipment purchases may qualify for exemptions — verify with Winnebago County.
