About ZIP 96813
ZIP boundaries are postal routes, not tax boundaries.
Hawaii's 4.5% is a general excise tax on the seller, not a sales tax — businesses commonly pass through 4.712% on Oahu to cover tax on the tax. For destination-based sourcing, Hawaii 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.
