About ZIP 40218
ZIP boundaries are postal routes, not tax boundaries.
Kentucky prohibits local sales taxes, so Louisville Metro's rate is the flat state 6% — though Kentucky has been expanding the tax to more services. For destination-based sourcing, Kentucky sellers should confirm the rate by full street address rather than ZIP alone — a single ZIP can cross a city limit or a transit-district boundary, and the rate follows the boundary, not the mail route.
