Castro County is one of the most productive agricultural counties on the Texas South Plains — cotton, grain sorghum, and cattle operations spread across some of the flattest, most fertile land in the state. Dimmitt serves as the county seat, and most of the county’s roughly 7,500 residents live with property taxes set by a short list of entities: the county itself, school districts, and the city. That simplicity is an advantage when it comes to protest — fewer entities means a cleaner picture of where your tax burden comes from and who to hold accountable when it rises.
Agricultural land in Castro County is often appraised under productivity valuation rather than market value, which can dramatically lower the taxable amount. If your ag land has been switched to market value — or if you’ve never applied for productivity valuation — that could be the single largest error on your tax statement. Residential property owners should verify their values every year. The protest process is free, and the Castro County Appraisal District accepts online protests at castrocad.org.

— Section 13, Declaration of Rights, Republic of Texas, 1836The farmers and ranchers of Castro County did not inherit this land to hand it piece by piece to a tax system that inflates values to meet someone else’s budget. The founders named Henri Castro honored the Republic of Texas — a man who recruited settlers at his own cost to build something lasting. The people of this county deserve that same respect: honest appraisals, public accountability, and a process that takes their protests seriously. Look up your value. File your protest. Attend the hearings. The people setting these rates work for you — as long as you hold them to it.
