About ZIP 78748
ZIP boundaries are postal routes, not tax boundaries.
Austin's Project Connect transit expansion is funded by property tax, not sales tax, because the city was already at the 8.25% cap. For destination-based sourcing, Texas 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.
