Dear Rajat sir,
I would like to add a little to what u have already said...
The carry forward and set off of business loss is restricted to 8 years by section 76,
But the unabsorbed depreciation is carried forward infinitely, because there is no such restriction under any provision, and the basic provisions regarding carry forward and set off of unabsorbed depreciation is actually based on the decision taken in the case of Virmani Intdustries Ltd... It needs mention that the unabsorbed depreciation can be set off against other any other incomes on the basis of the decision.
It is in my opinion, an incorrect proposition that business loss and unabsorbed depreciation can be equated with, and judged in relation to each other...
As per the words in sec 32, the brought forward depreciation is treated as current year depreciation allowance…. But section 71(2A) restricts only set–off of business loss against salary…
Ironically, unabsorbed depreciation can also arise in the computation of IFOS, see the sec 57 for allowable deductions… That can be set off against salary, cos of the loophole in section 71, that income from IFOS can be set off against any head… Pls note that the unabsorbed depreciation from IFOS is specified in sec 57, as per the words employed in section 57, is to be treated in exactly the same manner as the unabsorbed depreciation in sec 32…
So we find that unabsorbed depreciation is actually allowed to set off against salary as per the words employed in the income tax act… Because the law itself recognizes that business loss, loss in computing IFOS and unabsorbed depreciation are different, otherwise, such contradictory situation wont arise…
But still not possible to set off the same against salary because there is simply no provision in the return...
