Section 35-6-02-08-106 - Obsolescence1.Functional Obsolescence: The Assessor may optionally grant an allowance for functional obsolescence. If the Assessor chooses to grant such an allowance in addition to that already contained within the normal depreciation tables, it must remain within the allowance contemplated in the functional obsolescence tables annually furnished by the STC. Only in the most extreme circumstances would an allowance beyond that contemplated in the tables of allowance be allowed. Allowance for functional obsolescence beyond the amount provided in the tables must be elaborately justified by the taxpayer and scrutinized by the Assessor and STC.2.Economic Obsolescence: Economic obsolescence must be proved on a case-by-case basis to the Tax Assessor.35 Miss.
