Large cash in Hand

When I learned Cashflows statement, the cash and equivalents do hold cash in hand. A cash flow statement is prepared from income and balance sheet statement. There will be no consequences if you declare it in the balance sheet as per my opinion

“You are not required to disclose your personal assets in the ITR-4. Only assets held for business purpose are required to be shown in the ITR-4. You can show Nil (Zero) value in respect of Sundry Creditors, Inventories, Sundry Debtors, Cash in hand etc. There will be no error on validation and you can file your return.”
