ZIP code 53040 sales tax rates
ZIP code 53040 spans 12 different sets of sales tax jurisdictions in Wisconsin's Streamlined Sales Tax files on 2026-10-22, so there is no single sales tax rate for the ZIP code. The combined general rates of the candidates range from 5% to 5.5%. Look up the full street address (or ZIP+4) to find which one applies.
Accuracy: 5-digit ZIP code.
A published rate is not the tax due on a sale: taxability, sourcing, nexus and exemptions all change what is owed.
Data as of Oct 21, 2026 (Olympus publication) · Markdown version
- These are published sales and use tax rates by jurisdiction. They are not the tax due on a transaction and not a taxability determination: whether an item is taxable, which location's rate applies (sourcing), whether the seller must collect (nexus) and any exemption all change what is owed. Rates come from the Streamlined Sales Tax files the states publish or, where a result's source says so, from the state revenue department's own files and pages; confirm with the state before relying on them.
- This location matches 12 different jurisdiction sets, so no single rate is returned. Send a full street address or ZIP+4 to narrow it down. The candidate marked sst_default carries the jurisdictions the state's file assigns to the ZIP as a whole (states assign the lowest combined rate there); it is not necessarily the rate at a given address.
- Wisconsin's boundary file shortens street names to 20 characters, so a longer street name can match only at ZIP+4 or ZIP level.
