Tex. Tax Code § 23.41

(a) Land designated for agricultural use is appraised at its value based on the land's capacity to produce agricultural products. The value of land based on its capacity to produce agricultural products is determined by capitalizing the average net income the land would have yielded under prudent management from production of agricultural products during the five years preceding the current year. However, if the value of land as determined by capitalization of average net income exceeds the market value of the land as determined by other generally accepted appraisal methods, the land shall be appraised by application of the other appraisal methods.

(b) The comptroller shall promulgate rules specifying the methods to apply and the procedures to use in appraising land designated for agricultural use.

(c), (d) Repealed by Acts 1999, 76th Leg., ch. 574, Sec. 2(2), eff. June 18, 1999.

(e) Improvements other than appurtenances to the land, the mineral estate, and all land used for residential purposes and for processing harvested agricultural products are appraised separately at market value. Riparian water rights, private roads, dams, reservoirs, water wells, and canals, ditches, terraces, and similar reshapings of or additions to the soil for agricultural purposes are appurtenances to the land, and the effect of each on the value of the land for agricultural use shall be considered in appraising the land. However, the comptroller shall provide that in calculating average net income from land a deduction from income be allowed for an appurtenance subject to depreciation or depletion.
