Dear Maya,
I understand that the husband has paid LIC Rs 150,000 and tuition fees Rs 50,000. Kavitha is right, atleast in relation to tuition fees, to the extent that wife can claim exemption provided she has some source of income (which in anyways is a given assumption. No exemption would anyways be claimed, if there is no income).
But there could be catch while claiming exemption in case of LIC in case there is only one LIC policy.
Assuming there is only one LIC policy, claiming exemption for part of it in wife's tax return can't be considered as a settled judicial position and may lead to denial of exemption atleast at lower asessing officer level.
It may be noted that Indian tax laws doesn't provide for joint household taxation (other than in case of HUF). Thus husband and wife shall be treated separately for both the source exemption (payment of premium) as well application of exemption (tax return).
