Money considered as income for a month is not an asset for the same month. Any income added to a bank account is income for that month, and not a part of the account's asset value for the month. To figure the asset value of the account, subtract the
income from the bank balance. For the following month(s) any remaining income in the account is an asset.
Example: On September 5th a pension check of $100 is deposited in a savings account with a $400 balance. The new account balance is $500. Subtract $100 from the account balance, leaving an asset balance of $400 for
September. During the month of September $200 is withdrawn. On October 5th another $100 pension check is deposited. The asset balance as of October 5th is $300. The $100 remaining in the account from September's $100 pension check is now an asset in the
month of October and is added to the $200 asset balance from September.
