Answer: According to the provisions of the income tax laws, any recipient of gift has to pay tax if the aggregate of gifts received during a financial year exceed Rs. 50,000. However, gift received from specified relatives, such as spouse or daughter are not treated as income. Thus, they are fully exempt from income tax without any monetary limit. So, there will be no tax implications on making gifts to either your spouse or your daughter.
As far as taxation of income arising from the gifts so made is concerned, in case of gifts made to a spouse, the income is required to be clubbed with your income. But if the gift is made to a major daughter, then whether married or not, the clubbing provisions will not apply, and the interest income will be taxed in her hands. Do note that the clubbing provisions will continue to apply as long as the marriage subsists even when the asset gifted is converted to another asset. The clubbing provision will apply only on the income generated on the asset transferred, but not on the income generated from investments made of income already clubbed.
