CPT STUDENT HELP

GOOD MORNING CACLUB.

I AM RUNNING MY OWN INTERNET CENTER FROM LAST 3 YEARS. PREVIOUSLY I HAVE NOT FILED ANY I.T RETURNS,

NOW TO APPLY THE LOAN, BANKSERS ARE ASKING I.T RETURNS OF 3 YEARS.   CAN I FILE I.T FOR 3 YEARS AT A SINGLE TIME. IF NOT. HOW MANY YEARS THERE IS A POSSIBILITY TO FILE . AND WHAT WILL BE AN AUDITOR WILL BE CHARGED FOR THIS PROCESS. FEW EXPERTS ARE SAYING YES AND FEW ARE SAYING NO. I AM CONFUSED TOTALLY. 

PLEASE HELP.

WAITING FOR A VALUABLE REPLY.
