As per the policy info:
A)Death Benefit:
On death during the first policy year: Basic Sum Assured with Guaranteed Addition.(Rs 12 Lakh minimum in your example)
On death during the policy term after first policy year, excluding last policy year: 1/3rd of Basic Sum Assured with Guaranteed Addition. (4 lakh minimum)
On death during last policy year: 1/3rd of Basic Sum Assured with Guaranteed Addition along with loyalty addition, if any (4 lakh minimum)
B) Maturity Benefit
On maturity, the maturity Sum Assured along with Guaranteed Addition and Loyalty Addition, if any, shall be payable.
Maturity Sum Assured shall be 1/6th of Basic Sum Assured. (2 lakh min)
From above wordings, it appears that 12 lakh is basic sum assured only for death in the 1st year. Can you confirm from the agent?
80C (3A)Explanation.—For the purposes of this sub-section, "actual capital sum assured" in relation to a life insurance policy shall mean the minimum amount assured under the policy on happening of the insured event at any time during the term of the policy, not taking into account—
(i) the value of any premium agreed to be returned; or
(ii) any benefit by way of bonus or otherwise over and above the sum actually assured, which is to be or may be received under the policy by any person.
(So, the minimum amount on happening of the event is Rs 4 Lakh)
In that case, In my opinion, the policy maturity proceeds are taxable as the sum assured for the purpose of 80C or 10(10D) would be 400000.
More views welcome.
Maturity proceeds are taxable as income from other sources.
