Castell, TX — income, home value, property tax, and sales tax.
Property owners in ZIP code 76831, which takes in Castell, pay a county-level rate of 0.75% — a figure that points to a rural, working-class corner of the state rather than an affluent one. Combined with a 6.25% sales tax, the overall load leans on consumption as much as on holding property. Neither rate is punishing, yet the pattern fits a place where incomes stay low and land stays cheap. A household here likely feels the sales tax most in daily purchases, while the property levy stays contained because valuations never climb far.
