This has reference to computation of depreciation on fixed assets for the year ending 31st March 2015. Now depreciation is governed by Schedule II to Companies Act 2013. It is provided therein the useful life of a desktop is 3 years. So, if the WDV of a desktop is Rs 30,000/- as on 1st April 2014 will the depreciation on that asset for current year be Rs 10,000/-. Will the depreciation provided on this desktop in earlier years have to be recomputed. Is the date of purchase of asset relevant in this case.
