I purchased NSC 6 years back for Rs. 25,000, and it matured in this year i.e, Nov 2012 for Rs. 40,000. I did not claim any interest annually u/s 80C for deduction.
Now, as per my understanding,
1) Rs. 25000 (i.e, principal amount) is exempt from tax
2) Rs. 15000 (interest) portion is taxable as "income from other sources".
3) Can I also claim Rs. 15000 as deduction u/s 80C?
Please correct me if I am wrong and also, confirm on point 3.
Thanks.
