1. Temporary vs. Permanent Accounts
- Temporary (Nominal) Accounts: Accounts that track transactions within a single fiscal year (all revenue, cost of goods sold, and operating expense accounts). Their balances must be reset to zero at year-end so they can start fresh in the next period.
- Permanent (Real) Accounts: Accounts that track long-term balances across multiple years (all assets, liabilities, and equity capital accounts). These balances are never reset to zero; they are carried forward to start the next period as opening balances.
2. The Income Summary Account Tool
To close out temporary accounts, accountants use a temporary clearing account called the Income Summary Account.
3. Closing Ledger Mechanics
- Closing Revenue: Debit all revenue accounts to clear their balances | Credit Income Summary.
- Closing Expenses: Debit Income Summary | Credit all individual expense accounts.
- Closing the Summary Account: Debit Income Summary for the net profit amount | Credit the Owner’s Capital account.
