Why the rate here is not the whole story
Zapata County levies no sales tax of its own. Everything above the 6.25 percent state rate comes from special purpose districts rather than the county. A countywide special purpose district applies as well (Zapata County Assistance District), which lifts the floor across the county. The Comptroller lists 8.25 percent for every location in the county, so unusually for Texas one figure does cover the whole county. Texas caps the combined local share at 2 percent, so no address here exceeds 8.25 percent.
