What is the difference between the two scenarios mentioned below:
"Generally, it is advisable to declare accrued interest on NSC on a yearly basis. So, over the period of six years, you could declare the interest income for each year. In such cases, it does not amount to a huge sum. If you do not declare the interest on an accrual basis, then the entire interest earned (difference between the amount deposited and the maturity value) would accumulate in the year of maturity. You could then claim it under Section 80C, but it would be a huge amount and would be taxable at the current applicable tax rate."
How would declaring it yearly or once at the very end be different?
