Hello,

Once you enter the IIT campus and complete all the registration formalities and start your academics , you will receive a notification regarding your fee payment on your institute profile roughly within 15–20 days .

Then you have to upload the scanned pdf file of some documents in your institute profile which includes :

1. Your income certificate ( with digital signature / stamp of respective authority )

2. An income affidavit duly signed by a registered advocate / notary officer .

Format may be different for different IIT’s .

Once these uploaded certificates are verified , you will be notified on the institute profile that you are eligible for partial/full tution fee waiver.

Hope this helps.

Good luck!
