hi... In this case u can claim depreciation in this year for that year (as per AS-4) if the asset is put to use in the same year for the amount to be charged to dep. in that year. That dep amount will be charged to appropriation A/c so that it dont affect the current year profit. If u r charging dep at WDV method then the dep for current year will be charged after taking into considration that year's dep. Moreover if the asset is used for less than 180 days in the year of purchase, 50% dep will be charged and in case of 180 days or more full dep will be charged for that year. And if the Co. is a manufacturing Co. then u can claim additional dep on the same base of 180 days for the purchasing year. In case of necessity, claiming dep for that year year will be benificial from income tax point of view.
