Carrying things a little further, @circus07, a balance sheet contains only perpetual accounts. That means their current balances trace back to when you first started using the accounting system. They require correct starting balances, and every transaction affecting those accounts must have been properly entered. Since you were not concerned about such things previously, it seems very doubtful you will have entered the necessary transactions all that while.
When dealing with personal qualification for government programs, applying for loans, and so forth, the information needed is frequently much different from what you would be entering for a business. Often, you only need a basic list of assets (such as home, car, any investments, and bank balance) and a summary of liabilities (mortgage, personal loans). In fact, relevant authorities often provide an exact list of information required, sometimes with specific exclusions (due to regulations) of exempt items that would normally be included in the balance sheet of a business.
In the situation you describe, they are looking to exclude someone—as an example—who has no reported wage income, but inherited and lives off lucrative investments.
