Whatever interest in earned in a year gets reinvested with in initial principal within the same NSC investment. The entire interest earned for the entire period of 5 years qualifies for deduction under section 80c at the end of the term or at the time of maturity.

The above accrued interest should be shown as interest income under the head ‘income from other sources’. Then it should be claimed as deduction under section 80c.
