The Depreciation rates for computer software as per The Income Tax Act is 60% and as per the companies act 16.21% if the company is following Written down value method and 40% if the company is following Straight Line Method
My friends, I feel the rate of 40% and 16.21 % WDV and SLM as prescribed under the Cos. Act are for hardware and AS-26 Intangible Assets will prevail for amortization of software. As per the said standard any intangible asset has to be w/o within a period of max 10 yrs; as per para 65 of AS-26, the rate of amortization has to less than even 10 yrs considering the tech obsolescense.
