Which school district?
The 2020 Census places all of the homes inside San Benito city limits in San Benito CISD, so the table above uses it. Your district depends on your exact address. Look it up on the Cameron Appraisal District property search. The share comes from 2020 Census housing counts within current boundaries, and new streets at the edges can differ.
The 2020 Census counted 9,403 housing units inside San Benito city limits.
Units that tax only some homes
The Port of Harlingen Authority (2026 rate 0.020225, 2025 rate 0.01911) was on 2 of the 10 sampled homes inside city limits. 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.
A San Benito 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.
