Union County car sales tax: 8.5% to 10.25%

The rate in Union County

Where the rate changes inside Union County

10.25% — El Dorado.
9.5% — Junction City, Strong.
8.5% — Norphlet, Calion, Huttig, Junction City (outside city limits), Lawson, Mount Holly, Smackover, Strong (outside city limits).
This is why a county-wide figure is not enough here: two addresses in Union County can carry different tax on the same car, and in 3 of its ZIP codes the boundary runs through the middle so the ZIP alone cannot settle it. The calculator asks you which side you are on.
