Hi, Please refer the following section in income tax i.e. Sec 10 (10D) (Incomes not included in total income):
(10D) any sum received under a life insurance policy, including the sum allocated by way of bonus on such policy, other than—
(a) any sum received under sub-section (3) of section 80DD or sub-section (3) of section 80DDA; or
(b) any sum received under a Keyman insurance policy; or
(c) any sum received under an insurance policy issued on or after the 1st day of April 2003 but on or before the 31st day of March 2012 in respect of which the premium payable for any of the years during the term of the policy exceeds twenty per cent of the actual capital sum assured; or
(d) any sum received under an insurance policy issued on or after the 1st day of April 2012 in respect of which the premium payable for any of the years during the term of the policy exceeds ten per cent of the actual capital sum assured:
You have paid a premium of Rs. 180000 against sum assured of Rs. 1200000 which is more than 10% as specified in (d) above hence this amount will not be liable for tax as per my opinion. You can claim refund of the tax paid in the ITR
