you said it need not be shown under return.
my query is I how can I avoid reporting that 5 lakhs when my bank balance is reflecting it..
Everything falling into your bank account is not your income. You may transfer 1 crore from your broker account to your bank account. That 1 crore is not your income. However if that 1 crore contained Rs. 5 lakhs which is trading profit after deducting transaction charges, then that is your income even if you did not transfer to your bank account.
A money lender collects money and also lends money. This in and out transactions in bank statement may not reflect his income. His income is determined as per the rules given under the head "Income from Business or Profession"
Likewise, your income is to be determined based on different Heads
1. Income from Salary.
2. Income from House Property
3. Income from Business or Profession
4. Income from Capital Gains
5. Income from Other Sources
It may differ from what is hitting your bank account.
