Valuation variance: Assessing officers may refer capital asset valuations when declared value diverges from fair market value. Amendment replaces the test in section 55A permitting an Assessing Officer to refer valuation to a Valuation Officer where the assessee's claimed value 'is less than its fair market value' with a test allowing reference where the declared value 'is at variance with its fair market value,' thereby broadening the referral scope for ascertaining the fair market value of a capital asset.
