- 29 - Respondent argues that in order for Rev. Proc. 87-56, sec. 5.05, to apply, the “irrigation system must be a structure that is essentially an item of machinery and equipment, and there is equipment to which the structure is related from which we can determine the appropriate asset guideline class.” We agree with respondent. Because this Court has already decided that grapevines are permanent improvements to land and/or not tangible personal property, petitioners’ alternative argument must fail. Accordingly, we hold that respondent’s adjustments are sustained with respect to the irrigation systems and the well. Conversely, we hold that the trellising is not a permanent land improvement and that respondent’s determination with respect to the trellising is in error. To reflect the foregoing, Decision will be entered under Rule 155.Page: Previous 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29Last modified: November 10, 2007
