HELLO, assuming that you have taken the EAMCET (as you didnt mention the entrance exam particularly)

in general,there is no need of any income certificate for paying counselling fee,kindly note this.

You just need to login to the http://eamcet.tsche.ac.in website through your registration number and password(also your OTP).

PAY the counselling fee through ONline(via debit /credit cards or netbanking) and get the payment receipt.

YOU WILL BE NEEDED YOUR INCOME CERTIFICATE ONLY DURING THE UPLOAD OF DOCUMENTS and VERIFICATION .

SO,if there is a problem with issue of Certificate then do visit your nearest mee seva center and immediately apply for the income certificate which will be issued within a week with some amount of charge.

But if there is some other reason then immediately contact the EAMCET toll free  HELPline numbers during 10:00 am to 5 pm.

or email them at their email provided under the CONTACT US section,they will definitely help you out.

Make sure you get all the required documents ready before attending the counselling procedure.

ALL THE BEST,Hope this helped you.

THANK YOU :)
