Examples of temporary accounts are the revenue, expense, and dividends paid accounts. Any account listed in the balance sheet (except for dividends paid) is a permanent account. A temporary account accumulates balances for a single accounting period, whereas a permanent account stores balances over multiple periods.
For example, a closing entry is to transfer all revenue and expense account totals at the end of an accounting period to an income summary account, which effectively results in the net income or loss for the period being the account balance in the income summary account; then, you shift the balance in the income summary account to the retained earnings account. As a result, the temporary account balances are reset to zero, so that they can be used again to store period-specific amounts in the following accounting period, while the net income or loss for the period is accumulated in the retained earnings account.
It is also possible to bypass the income summary account and simply shift the balances in all temporary accounts directly into the retained earnings account at the end of the accounting period.
As an another example, you should shift any balance in the dividends paid account to the retained earnings account, which reduces the balance in the retained earnings account. This resets the balance in the dividends paid account to zero.
The following journal entries show how closing entries are used:
1. Shift all $10,000 of revenues generated during the month to the income summary account:
2. Shift all $9,000 of expenses generated during the month to the income summary account (there is assumed to be just one expense account):
3. Shift the $1,000 net profit balance in the income summary account to the retained earnings account:
All modern accounting software automatically generates closing entries, so these entries are no longer required of the accountant; it is usually not even apparent that these entries are being made.
