80 ttb with respect of Post Office investment

Yes 80TTB provide deduction of interest on all kinds of deposit

If that be so, the interest accrual on NSC should not qualify for 80 c benefit, I guess. The logic being there cannot be double benefit.
Kindly confirm. Thank you.

Thing is not like that... means like deduction on interest on housing loan available under section 24b and 80EE... thus like interest on NSC is available with 80C and 80TTB for SENIOR CITIZEN ONLY... if assessee have exhaust its limit under section 80C can claim deduction under section 80TTB..

I seek a clarification. Do you mean that first I have to claim 80 c on NSC interest and subsequent if needed 80 ttb on the same?
Let me be more specific. If I claim 80 ttb for all my interest received in Bank and Post Office deposits including NSC interest, and 80 D benefit, my taxable income comes less than the exemption limit. Can I do it without resorting to availing 80 c on NSC interest?
Thank you.

Yes you can do..

I thank you again.

Agree with @ CA Abhay Gupta
