Hello!

Yes you can get a fee waiver if your son got admission into IIIT pune for CSE and your family annual income is below 5 lakh but you will not get full fee waiver. You will get 2/3 of the tuition fee waiver. You will need to pay rest 1/3 of the fees. Only annual family income below 1 lakh get full fee waiver.

Also Make sure to submit your valid income certificate and that certificate should not be older than 6 months.
