The income statement amounts are best calculated for a specific period of time by using the accrual basis of accounting. Under the accrual basis the revenues are the amounts that were earned (not the amount of cash received), and the expenses are the amounts that best match the revenues or were used up during the period (not the cash that was paid out).
Income statement accounts are used to sort and store transactions involving:
Large companies may have thousands of income statement accounts in order to budget and report revenues and expenses by divisions, product lines, departments, and so on.
Income statement accounts are also referred to as temporary accounts or nominal accounts because at the end of each accounting year their balances will be closed. This means that the balances in the income statement accounts will be combined and the net amount transferred to a balance sheet equity account. In the case of a corporation, the equity account is Retained Earnings. In the case of a sole proprietorship, the equity account is the owner's capital account. As a result, the income statement accounts will begin the next accounting year with zero balances.
When a corporation has preferred stock, the dividends on preferred stock are deducted from a corporation's net income in order to arrive at earnings available for common stock. Earnings available for common stock is reported on the income statement. It is also used to calculate the common stock's earnings per share. The earnings per share figure is reported on the income statement when the corporation's stock is publicly traded.
The retailer can record the delivery surcharges in a separate operating revenue account. In other words the sales revenues account could be used to record the revenues excluding the surcharges and then another sales revenue account could be designated as the delivery surcharge revenues account. Those two accounts would then be added together to report total operating revenues.
In the following accounting period, the accrual-type adjusting entries will usually be reversed. They are reversed or removed because the actual invoices or other documents containing the accrued revenues or expenses will be arriving and will be entered into the accounting records by the bookkeeper or the accounts payable clerk.
