Advance amount deposited in relation to agricultural land

Sorry to say that as per sec. 269ST of IT act, no person is allowed to receive cash of Rs. 2 lakhs or more from anyone on any single day or any occasion. So, difficult to protect yourself when  received such an amount in cash on sale of agricultural land. 

Is it Rural Agricultural Land ?
Where is it located ?
Does the buyer have bank account ?
Do you have bank account in your name ?
Where is your brother's bank account ?

Here again you can not give or take cash as advance or loan in excess of 20000/-. Otherwise 100% penalty.

For what reasons you accepted cash and then deposited in bank account.

Under Income Tax, there is a ban on cash transactions over and above 2 lakhs.

Here the receiver of cash will be in trouble. Penalty is 100% of transaction amount in cash
