Property Tax
Nine Different Entities Tax Property in Webb County
Your property tax bill in Webb County can include charges from up to nine separate taxing units — each setting its own rate.
Nine different groups can tax your property in Webb County. They are: Webb County itself, three school districts (Laredo ISD, United ISD, and Webb Consolidated ISD), three cities (Laredo, Rio Bravo, and El Cenizo), Laredo Junior College District, and a drainage district. Which ones show up on your bill depends on where your property sits.
Each group sets its own tax rate. Your total tax rate is the sum of all the rates that apply to your address. The tax assessor-collector adds them together and sends you one bill. To see each group and its contact info, check the Texas Comptroller's county directory for Webb County.
