See if your income certificate is issued after 31st of March 2021 then only your income certificate will be accounted as valid. Now as you have uploaded a previous certificate then if you get option in counselling then you can change or you have to produce both the documents in your verification round.

I hope this answer helps. All the very best for your future endeavors!

Dear aspirant,

As you mentioned that you have uploaded the income certificate in registration form and now that your income has changed you have made a new one.

So let me tell you that during verification of documents they would ask for the same income certificate which you have uploaded in the registration form irrespective of the fact that it's validity is over not.

So don't worry you can upload it.
