How the tag cost works
Your tag's ad valorem tax is the vehicle's value × 30% assessment × Harrison County's (and your city's) millage, minus the statewide Legislative Tag Credit. Because millage is set locally and stacks inside city limits, a Gulfport resident pays well above someone in the unincorporated county. For your exact figure, use the Harrison County tax collector.
