Which school district?
Alamo city limits cross more than one school district, and the school district is the biggest line on the bill. About 76.0% of the homes are in Pharr-San Juan-Alamo ISD, so the tables on this page default to it. Your district depends on your exact address. Look it up on the Hidalgo County Appraisal District property search.

Units that tax only some homes
No other taxing units showed up on the 9 sampled homes inside Alamo city limits on the 2025 roll. A public improvement district (PID) in a newer subdivision bills an assessment, not a tax rate; the title company can tell you if a lot has one.
An Alamo mailing address can sit outside city limits, where there is no city tax and an emergency services district may tax instead. Your appraisal district record lists every unit on your home.
