I am not able to understand the following points, kindly share your views on this

1. No tax deduction at source.

2. Investment up to Rs 1,00,000/- per annum qualifies for Income Tax Rebate under NSC - section 80C of IT Act.

3. The interest accruing annually but deemed to be reinvested will also qualify for deduction under NSC - section 80C of IT Act.

What is the amount of deduction from the interest occured say for ex: Rs. 150.90 after 5 years or what percentage is taxable? And, how should get tax benefits on this?

What if I invest 2000 PM in NSC, even then is there is any tax during withdrawls? In general what is tax percentage during withdrawals on NSC, bank fixed deposits and PPF?

waiting for your reply.
