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 = NI=extTotalRevenuesextTotalExpensesNI = ext{Total Revenues} - ext{Total Expenses}

    • 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 = 1,000,0001{,}000{,}000):

      • Debit Revenues for 1,000,0001{,}000{,}000

      • Credit Income Summary for 1,000,0001{,}000{,}000

    • 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 = EE):

      • Debit Income Summary for EE

      • Credit each Expense account for its individual balances totaling EE

    • 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 NINI

      • Credit Retained Earnings for NINI

    • If NI < 0 (net loss):

      • Debit Retained Earnings for NI-NI

      • Credit Income Summary for NI-NI

    • Net effect: Retained Earnings increases by net income (or decreases by net loss).

    • Net income example (if Revenues = 1,000,0001{,}000{,}000 and Expenses = XX):

      • NI=1,000,000XNI = 1{,}000{,}000 - X

      • Entry moves NINI 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 DD (dividends total)

      • Credit Dividends for DD

    • 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 1,000,0001{,}000{,}000.

    • 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:rac23imes15,000=10,000rac{2}{3} imes 15{,}000 = 10{,}000

    • Use this type of calculation to verify journal entry amounts or to allocate portions of revenue/expense allocations when reviewing problems.

  • Formulas and key equations (LaTeX)

    • Net income for the period:
      NI=extTotalRevenuesextTotalExpensesNI = ext{Total Revenues} - ext{Total Expenses}

    • Closing entries (summary form):

    • Close Revenues to Income Summary:
      extDebit:Revenues extCredit:IncomeSummary extTotal:extRevenuesext{Debit: Revenues} \ ext{Credit: Income Summary} \ ext{Total: } ext{Revenues}

    • Close Expenses to Income Summary:
      extDebit:IncomeSummary extCredit:Expenses extTotal:extExpensesext{Debit: Income Summary} \ ext{Credit: Expenses} \ ext{Total: } ext{Expenses}

    • Close Income Summary to Retained Earnings (net income case):
      extDebit:IncomeSummary extCredit:RetainedEarnings extAmount:NIext{Debit: Income Summary} \ ext{Credit: Retained Earnings} \ ext{Amount: } NI

    • Close Dividends to Retained Earnings:
      extDebit:RetainedEarnings extCredit:Dividends extAmount:Dext{Debit: Retained Earnings} \ ext{Credit: Dividends} \ ext{Amount: } D

    • Ending Retained Earnings relationship (for the period):
      RE<em>end=RE</em>begin+NIDRE<em>{end} = RE</em>{begin} + NI - D

    • Net assets check after closing: post-closing trial balance should include only permanent accounts (no temporary accounts).

  • 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
