Who handles your property taxes in Castro County
The value that drives your tax bill is set at 204 S.E. 3rd St. (Rear) in Dimmitt, the home of the Castro County Appraisal District. They decide what your home or land is worth for tax purposes, and that is the office where you contest a value you think runs too high. You can reach the district at 806-647-5131 or castrocad.org, where the exemption and protest forms live.
Billing and payments are a separate job, run through the Tax Assessor-Collector at the courthouse. If you are not sure whether an exemption application, a protest, or a payment belongs at the appraisal district or the tax office, call the appraisal district first: a value question, a homestead exemption, or an ag-use application all start there, not at the collection window.
