After you get income from your securities, you can gift (WITHOUT ANYONE PAYING TAXES) either:
1) 15,000 per person (30,000 married) every year, or
2) 5,450,000.00 per person (11mm if married) ONE TIME to someone without them or you paying taxes.
It is how wealthy people reduce their tax brackets in order to not pay the highest tax brackets.
