As concerned with your query, it is clearly mentioned in clause (XI) of sub section (2) of sec.80(C)
-
as a contribution in the name of any person specified in sub-section (4) for participation in any such unit-linked insurance plan of the LIC Mutual Fund 80a clause (23D) of section 10, as the Central Government may, by notification *in the Official Gazette, specify in this behalf;
*For notified Unit Linked Insurance Plan of LIC Mutual Fund, see Taxmann's Master Guide to Income - Tax Act.
And also the sub section (3) of Section 80-C read as under :
"The Provisions fo sub section (2) shall apply only to so much any premium or other payment made on an insurance policy other than a contract for a deferred annuity as is not in excess of twenty per cent of the actual capital sum assured."
So it will only be the 20% i.e Rs.10000/-. Hope this will clarify you. If i am wrong, plz.. correct me.
