Closing Entries: Temporary vs Permanent Accounts and Income Summary
Overview
Focus: closing entries in accounting to reset temporary accounts and update the permanent accounts for a new period.
Key idea: Incoming revenues and expenses are for a specific period. To start the next period clean, we zero out temporary accounts.
Temporary accounts include: revenues, expenses, dividends, and income summary (a temporary clearing account used only for closing).
Permanent accounts are the balance sheet accounts and are not closed at period end.
The closing process ensures the ending Retained Earnings reflects the period's net income and any dividends paid.
The post-closing trial balance should only include permanent accounts (temporary accounts should have zero balances).
Key concepts and terminology
Income statement accounts = revenues and expenses (temporary)
Statement of retained earnings = updates retained earnings (temporary for the period, then closed)
Income Summary = a temporary account used to accumulate net result of revenues minus expenses during closing
Normal balances concept (for exams):
Assets, Expenses, and Dividends typically have debit balances
Liabilities, Equity (including Revenues) typically have credit balances
Net income (NI) for the period =
Ending Retained Earnings (RE_end) is updated only after closing entries; it carries forward into the next period.
The closing process: four steps (in order commonly used)
Step 1: Close revenue accounts to Income Summary
Rationale: revenues have credit balances and need to be zeroed for the new period
Journal entry (example with total revenues = ):
Debit Revenues for
Credit Income Summary for
This transfers the revenue balance to Income Summary.
Step 2: Close expense accounts to Income Summary
Rationale: expenses have debit balances and need to be zeroed for the new period
Journal entry (example with total expenses = ):
Debit Income Summary for
Credit each Expense account for its individual balances totaling
After this step, Income Summary holds the net result: credit balance equals total revenues minus total expenses.
Step 3: Close Income Summary to Retained Earnings
Rationale: transfer the period’s net income (or net loss) to Retained Earnings
If NI > 0 (net income):
Debit Income Summary for
Credit Retained Earnings for
If NI < 0 (net loss):
Debit Retained Earnings for
Credit Income Summary for
Net effect: Retained Earnings increases by net income (or decreases by net loss).
Net income example (if Revenues = and Expenses = ):
Entry moves into Retained Earnings as above.
Step 4: Close Dividends (or Owner’s Draw) to Retained Earnings
Rationale: dividends reduce retained earnings
Journal entry:
Debit Retained Earnings for (dividends total)
Credit Dividends for
Outcome: Retained Earnings is reduced by the amount of dividends paid during the period.
Special notes and tips mentioned in the transcript
You can choose the order of Step 1 and Step 2 (revenues vs expenses) depending on your chart of accounts; the instructor uses a specific sequence for ease but the order can be flexible.
The income statement and the statement of retained earnings are for a period (year/month).
The “income summary” account is opened only as long as it takes to close the accounts; it should be closed in Step 3 to Retained Earnings.
You should be mindful of normal balances when preparing for exams; the normal balance concept may shift in future chapters, but remains a fundamental check for the current exam.
After closing entries are posted, you should prepare a post-closing trial balance to ensure columns balance; if the post-closing trial balance does not balance, you must review the closing entries.
The ending Retained Earnings balance reflects the net income and dividends for the period; it does not update until the closing entries are completed.
Worked example from the transcript (conceptual)
Revenues for 2021 totaled .
Suppose ending balances before closing would roll into 2022 if not closed; closing resets temporary accounts to zero for the new period.
Example calculation of a fraction used in a problem:
Use this type of calculation to verify journal entry amounts or to allocate portions of revenue/expense allocations when reviewing problems.

Quick recap of the practical workflow
Identify temporary vs permanent accounts
Sum Revenues and Expenses to determine NI
Move Revenues to Income Summary (close)
Move Expenses to Income Summary (close)
Close Income Summary to Retained Earnings (net income or net loss)
Close Dividends to Retained Earnings
Update and verify the post-closing trial balance
Prepare next period with all temporary accounts reset to zero
