You can withdraw (in the middle of six year) the interest of NSC, only in very rare circumstances. You normally withdraw it on maturity. And at that time full interest is not taxable. Only last year interest is taxable. Because previous years interests, is already reinvested. So only the 6th year interest which is not reinvest is taxed on the year of receipt.
