In the case of a change in the taxpayer's organizational structure, any substituted basis of value other than the original cost shall not be used if the taxpayer's organizational structure or entity change embraces the same depreciable tangible personal property.
Any tangible personal property that has been appraised by the Office shall be reported on the return at that appraised value for the tax year being appraised.
Regarding the allowance for depreciation for subsequent years, the Office shall advise the taxpayer whether the depreciation shall be allowed on appraised tangible personal property depending on the circumstances surrounding the appraisal made.
