Accounts can be classified as either personal or impersonal. Personal accounts relate to individuals, companies, or organizations and can be further broken down into natural persons, artificial persons, and representative persons. Impersonal accounts can be real or nominal. Real accounts represent assets and appear on the balance sheet, classified as tangible or intangible. Nominal accounts relate to income and expenses and appear on the profit and loss statement. Proper classification of accounts helps ensure correct financial statement preparation and accurate bookkeeping entries.
