Yes, you can upload the income certificate for the second counselling round if you did not upload it during the first counselling. Here are the key points:

1. Online Generation: You can upload an online-generated income certificate if it is signed or sealed by the respective authorities. If it is not signed, you can get it attested by an authorized officer

2. Verification: If your income certificate is not verified during the first round, you can submit it in the second round. You do not need to go through the certificate verification process again; you can simply visit the help line center where you got your first phase certificate

3. Fee Waiver: If your fee waiver status was NO after verification in the first round, you can still submit the income certificate in the second round to potentially change your fee waiver status

For more detailed guidance, contact the relevant authorities or the help line center directly.
