No entry is made to a company's general ledger for outstanding checks when preparing a bank reconciliation. The reason is outstanding checks are an adjustment to the bank balance. Outstanding checks are not an adjustment to the company's Cash account in its general ledger.
However, if a company voids one of its outstanding checks, the company will need to make an entry to its general ledger. The entry will debit Cash in order to increase the account balance. The credit portion of the entry will likely be to the account that was originally debited when the check was issued.
