Written down value rules: formulaic WDV computation and continuity across specified corporate transfers ensure consistent depreciation treatment.
Computation of written down value uses three treatments: actual cost for assets acquired in the year; actual cost less depreciation actually allowed for assets acquired earlier; and block computation by [(A - D) + B - C] - E with statutory caps. The provision maps WDV/actual-cost continuity across specified corporate transfers (holding/subsidiary, amalgamation, demerger, LLP conversion, corporatisation), deems carried-forward depreciation to be depreciation actually allowed, and requires revaluation/book-depreciation adjustments where earlier years lacked tax computation.
