TIPS ON NATIONAL SAVINGS CERTIFICATES

1. There is no maximum limit on the purchase of NSCs.
2. However, investments upto Rs 1.5 lakh overall limit, for all qualifying instruments taken together, will qualify for tax rebate under Sec 80C.
3. Interest on NSC gets compounded annually, and also qualifies for Sec 80C tax rebate every year within its overall limit of relevant financial year. 
4. Upon maturity, total investment and accrued interest is received as maturity value. 
5. As there is no TDS on NSC interest, applicable tax is paid on it annually by NSC holder himself.
6. If the NSC maturity proceeds are not withdrawn, the scheme becomes available for post office savings scheme interest for 2 years.
7. If NSC certificate gets lost, there's a facility to get a duplicate certificate at the post office. 
8. If you have a photocopy of the certificate, the process to get a duplicate certificate gets simplified. 
9. Succession laws of the land will have to be complied with too.
