Fd in husbands a/c for senior citizen fd interest benefit

Please any one can advise me on above?

In that case Bank will treat it as FD of your father, and deduct TDS whenever applicable.

Your father will have to claim the excess amount of TDS by filing IT return, as such the interest income will be assessed under your father's income.

So, calculate the taxability as per slab rate of your father and mother individually, and take call.
