hello,
i have invested in fd and mutual funds in my son's name who is now 5 years old. he's getting good amount of income from it which exceeds the exempted threshold.
is there any rule stating that i have to show his income attached to mine or can i show his income in my wife's file too?
which clause defines this?
please help me.
