Carried forward & set of

In your case, only unabsorbed depreciation can be carry forward.Business loss shall not be allowed to be carry forward.

However, in case the loss is to be set-off against some other income arising in the same year, it is allowed to be set-off even if the return is filed after the due date of filing of returns.

Although the loss of the current year cannot be carried forward unless the return of loss is submitted before the due date but the loss of earlier years can be carried forward if the return of loss of that year(s) was submitted within the due date and such loss has been assessed.

Thank you but can you give me the answer of this question:
X ltd file its return of loss for the A.Y 2019-20 on 1.12.19. following data is taken from return submitted by the company.
business loss fir p.y 18-19 ( before depreciation) 1,70,000
depreciation 30,000
short term capital loss 45,000
long term capital gain 10,000
income from other source 23,000
unabsorbed depreciation pertaining to A.Y 2017-18 and A.Y 2018-19 which has been determined in pursuance of return filed 75,000
compute the amount of loss that can be carried forward by X ltd.
A. 1,05,000
B. 30,000
C. .2,87,000
D. nill

30000 UAD can be carried forward. No other loss can be carried forward.

Why only 30,000 , 75,000 unabsorbed depreciation is why not carried forward & income from other sources can ve set off against both or not ?

Yes. I meant 30000 for the current year. .. and 75000 for previous years.. both

& income from other sources 23000 is to be set off from depreciation or not ?

23000 will be setoff from business income..UAD can be setoff but since it is available for adjustment for unlimited years, the priority for adjustment shall be on the last rank

But
1. income from other sources can be set off against business loss even if company has file belated return ?
2. if in above answer is no so we can choose the income from other sources set off against UAD because no other loss in that year to set off this income
