In case you are paying towards a health insurance bought for your parents, then you can get an exemption of up to Rs 20,000 annually for each parent.
If you are incurring expenditure for the treatment of a handicapped dependent, then you can claim a deduction of Rs 50,000 or the expenses incurred, whichever is lesser, under section 80DD. For severe handicap conditions, the deduction limit is enhanced to Rs 1 lakh. And, you can claim tax relief under Section 80D and Section 80DD separately.
