Notes:
a) Long Term Capital Gain is a term used in Income Tax Act. Such a term will not be found in the Companies Act. Hence, this term has been understood accordingly. Further, LTCG, being an item as per Income Tax Act, is of a permanent nature, hence, no deferred tax asset / (liability) will arise on the same.
b) Disallowance u/s 40 due to non-deduction of TDS is considered to be of a permanent nature, on the basis of assumption that the amount of TDS will not be deducted in future years and consequently, will not be paid to the Government. If it is assumed that the amount of TDS will be deducted and paid in future years, then the amount of expenses disallowed u/s 40 will be considered as a temporary difference and Deferred Tax asset will arise on the same.
c) Dividend received on shares of a Company is exempt from Income Tax and hence, is in the nature of permanent difference.
