Profits from life policies with protection < 20x annual premium will be taxed on withdrawal - even those policies with protection >20x annual premium will be taxed on premature withdrawals. Equity MFs, on the other hand, are exempt from long term capital gains.

An additional category of Rs 50,000 has been created for children's tuition fees, life and health insurance - this is good news, though its been diluted by restricting it only for policies with protection > 20x annual premium. The concern, however, is that the original limit of Rs 100,000 - hitherto shared between life insurance, provident funds, etc - has been kept intact but the eligible asset classes have not been specified.
