Mostly a salaried person can save by obtaining a Housing loan (and purchasing a house) through which u can claim up to 2 lakhs (self occupied) as interest and upto 1.5 lakh for principal repayment.
Thus, you can earn more income through Rent and also claim deductions for interest and principal payments.
there are other options for deductions like life insurance, tuition fees for children, medical insurance, NPS, etc.
I can help in detail based on your personal info
