TAXATION OF MUTUAL FUNDS OPENED IN MOTHER'S NAME

1. Income tax is all about "source" of "income and expense", period.

2. Investing money in your mother's name is a "gift" out of your income first, being given to an adult who falls in eligible list of relatives.

3. Gifting money to your mother is without any tax liability to you, and then investing it in her name is perfectly legal strategy, with no capital gains taxes incurred by you. 

4. There will be no income tax on your mother too, if her own total income, including capital gains, are within her basic exemption limit.

5. Always maintain records of intra-family transactions (gift deed, etc.), as evidence of contribution in their assets, to ensure "source" of income - by you as well as them.

6. Once this "income & expense" trail is established, you can invest in your mother's name, singly (you being nominee) or jointly (you being second holder), as per future convenience.
