This is the link to download certificate format.
As you can see that the pdf in the website is only a format. Which means you have to take the hard copy of the certificate written in this format only. For example, in the given GEN-EWS certificate format the financial year given is 2024-25 but you are appearing for JEE Main 2026 so you need to edit the certificate and write that the gross annual income of his/her family” is below
Rs. 8 lakh (Rupees Eight Lakh only) for the financial year 2025-2026
Hello,
If you’re appearing for Class 12 (HSC) in 2026 and don’t have your board admit card or roll number yet, you can leave the “Registration No./Enrollment No./Roll No.” field blank or enter “NA” (Not Applicable) if the form allows.
Do not enter your school GR number, as it’s not recognized by the exam board or NTA.
Once your board issues the admit card or registration number, it can be updated later during JEE Main form correction or at the time of result verification.
So, for now, safely enter “NA” or leave blank — not your GR number.
Hope you understand.
Hello,
For JEE Main EWS certificate, your parent's income certificate is required, not yours.

The certificate should be issued by a competent government authority and must be valid for the current financial year.
Hope you understand.
