hi krishna,
u/s 80 C u can invest 1,00,000 (pf employees contribution also exempted)
u/s 80 D medical insurence--15000(if the dependents are non-senior citizens)
u/s 80 D Medical insurence --20000(if the dependents are senior citizens)
u can claim your hra u/s 10 in case if u are staying in your own house then fill form 10BA where in u can get exemption upto 3000 per month.
Incase any housing loans can reduce your tax based on the split up of Principal and interest components
Cheers
