Short answer
Wisconsin taxes vehicle sales at 5%. Wisconsin taxes the price after the trade-in is deducted. Wisconsin exempts out-of-state buyers only under specific conditions: Two conditions, not one: the buyer must not be a Wisconsin resident AND the vehicle's use in Wisconsin must be limited to removing it from Wisconsin. Any Wisconsin use before removal (Pub 202's example is driving it to a vacation home) voids the exemption. The exemption covers motor vehicles and truck bodies including semitrailers, but not trailers or car caddies. Document it with an exemption certificate (Form S-211) from the buyer or by completing section "E" of Form e-MV11. Also available to nonresident corporations (incorporated outside Wisconsin). Wisconsin credits sales tax legally paid to another state, so the same dollars are not taxed twice. All of this describes a retail purchase from a dealer; leases and private-party sales run on different rules in most states.

From the desk
Wisconsin keeps it to a state rate plus modest county add-ons, keyed to where the vehicle is customarily kept. Clean trade-in treatment makes the desk math easy; the Illinois border paperwork keeps it interesting.
Selling to an out-of-state buyer in Wisconsin
Wisconsin exempts out-of-state buyers only under specific conditions: Two conditions, not one: the buyer must not be a Wisconsin resident AND the vehicle's use in Wisconsin must be limited to removing it from Wisconsin. Any Wisconsin use before removal (Pub 202's example is driving it to a vacation home) voids the exemption. The exemption covers motor vehicles and truck bodies including semitrailers, but not trailers or car caddies. Document it with an exemption certificate (Form S-211) from the buyer or by completing section "E" of Form e-MV11. Also available to nonresident corporations (incorporated outside Wisconsin).[1]
None of it works without Form S-211 (Wisconsin Sales and Use Tax Exemption Certificate), or section "E" of Form e-MV11, completed at delivery. Skip the form and the state looks to the dealer for the tax, not the buyer.
The tax answer is only half the job. The desk still has to move the title, issue the temp tag, and keep the deal from stalling while paperwork crosses state lines, and that chain is what Voltra's title tracking holds in one view.
Buying in Wisconsin from out of state
If you live in another state and buy in Wisconsin, the deciding rule is where the vehicle gets registered: your home state's tax applies at registration, and what happens at the Wisconsin sale depends on the row above. Wisconsin credits sales tax legally paid to another state, so the same dollars are not taxed twice.[1]

Bordering states
Cross-border deals from Wisconsin most often involve Iowa, Illinois, Michigan and Minnesota. No two pairings behave the same; run the exact combination through the out-of-state checker.
Vehicle-type exceptions
The nonresident exemption is narrower than most: it reaches only motor vehicles and truck bodies (semitrailers included) as defined in Tax 11.83(1), Wis. Adm. Code. Trailers and car transport devices such as car caddies do not qualify because they are not motor vehicles or truck bodies, and neither do boats, snowmobiles, ATVs, UTVs, off-road motorcycles, or a separately sold slide-in camper. County and city tax on boats, recreational vehicles and aircraft is sourced the same way as motor vehicles, by where the item is customarily kept.[1]
