Starr County sits on the Rio Grande in South Texas, with Rio Grande City as its county seat. The county has one of the lowest median property tax bills in Texas — not because the rate is low, but because median home values are among the most modest in the state. A 1.28% rate on a $33,000 median home produces a very small dollar bill, but it still represents a meaningful share of household income in a border community where wages are modest.
At 1.28%, Starr County’s effective rate is above the national median. The combination of a higher-than-average rate applied to very low home values means the system is particularly burdensome relative to local income. Half of those who protested in 2024 achieved reductions. Your deadline is May 15, 2026.

“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”
— Section 13, Declaration of Rights, Republic of Texas, 1836Starr County’s border families have built their lives on the Rio Grande on modest incomes that the South Texas economy has historically constrained. The founders of the Republic wrote that no property shall be taken without consent and just compensation. A 1.28% rate on a $33,000 home takes a proportionately larger share of a Starr County household’s income than the same rate on a $300,000 home anywhere else in Texas. That principle demands accuracy. Look up your value. File your protest. The Rio Grande deserves fair assessment.
