A capital gain will arise only on the transfer of a capital asset. Section 47 specifically provides that a gift is not a transfer except where the gift is of shares or debentures allotted under an employee stock option scheme. In your case, assuming that the shares do not contain shares allotted under employee stock option scheme, it can be said that no capital gains will arise on the gift. There is no limit, and no tax will be levied whatever may be the quantum of gift.
