Sec.32(2) provides that Where, in the assessment of the assessee, full effect cannot be given to any allowance under sub-section (1) in any previous year, owing to there being no profits or gains chargeable for that previous year91, or owing to the profits or gains chargeable being less than the allowance, then, subject to the provisions of sub-section (2) of section 72 and sub-section (3) of section 73, the allowance or the part of the allowance to which effect has not been given, as the case may be, shall be added to the amount of the allowance for depreciation for the following previous year and deemed to be part of that allowance, or if there is no such allowance for that previous year, be deemed to be the allowance for that previous year, and so on for the succeeding previous years.
So my friends, it clearly indicated that we have to treat Unabsorbed Depreciation as the Depreciation of Current Year until it is fully absorbed so according to me it cab not be set-off against Income from Salary as it is allowance deductible u/s 32(1) every year as stated in the section clearly..
