Dimmitt, Texas
Dimmitt is a city in Castro County on the flat, high tableland of the Llano Estacado in the Panhandle, about 54 miles southwest of Amarillo. The surrounding plains are given over to large-scale irrigated agriculture, with grain crops, cotton, and cattle feeding operations spread across the level farmland. It functions as a trade and service center for this intensively farmed corner of the High Plains.
Property here runs through the Castro Central Appraisal District and the county tax office — the homestead exemption, the appraisal cap, protests, and any MUD, PID, or special districts all sit at the parcel level. The Castro County notes below cover the practical details, with the official county directory for the appraisal district and tax office.
