The entire amount can be written off in P&L a/c in the same year but provisions of appendix A of AS-26 will apply
Para 13 clearly states
The depreciable amount of a software should be allocated on a
systematic basis over the best estimate of its useful life. The amortisation
should commence when the software is available for use
If the useful estimated life is less than one year then it can be writenn off in same year
There is a rebuttable assumption that the estimated useful life of the software shall be 3-5 years
this is an emplied assumption unless there is something contrary like in this case
Asset is to be capitalized and written off in same year
Don't we capitalized the asset liable to 100% depriciation and writeoff within the same year?
Please clarify Where my understanding is wrong
