About ZIP 99803
ZIP boundaries are postal routes, not tax boundaries.
Juneau charges 5% year-round but drops to 3% from October through March, and caps tax on single items above $14,900. For destination-based sourcing, Alaska 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.
