Purpose of the Post-Closing Trial Balance
The post-closing trial balance is prepared after the period-end closing entries have been posted. It lists the remaining ledger account balances, with debit balances in one column and credit balances in another. Its main purposes are to check that the ledger remains in balance and to confirm that the accounts needed for the next period have been carried forward.
The key distinction is between permanent accounts, whose balances continue into the next accounting period, and temporary accounts, whose period activity is closed out. The earlier material on closing revenue and expense accounts and closing dividends into retained earnings establishes the closing process. Here, the focus is on checking its result.
Permanent accounts include assets, liabilities, and equity accounts such as common stock and retained earnings. Contra accounts, such as accumulated depreciation and an allowance for uncollectible accounts, are also permanent: they remain in the ledger and reduce the related asset balance. Temporary accounts include revenue, expense, and dividends accounts. Their balances are closed so that the next period begins with no balance carried forward in those accounts.
What the Trial Balance Should Contain
Each listed amount is the account’s ledger balance after closing, not its activity during the period. A debit balance is shown in the debit column; a credit balance is shown in the credit column. The normal balance helps identify the expected side: assets and expenses typically have debit balances, while liabilities, equity, and revenue typically have credit balances. Contra accounts generally have the opposite balance from the accounts they reduce.
| Account type | Post-closing treatment | Examples |
|---|---|---|
| Assets and contra assets | Carry forward their remaining balances | Cash, equipment, accumulated depreciation |
| Liabilities | Carry forward their remaining balances | Accounts payable, notes payable |
| Equity | Carry forward the balances after closing | Common stock, retained earnings |
| Revenue and expenses | Close to zero | Service revenue, wages expense |
| Dividends | Close to zero | Dividends |
Retained earnings is especially important to check because closing activity transfers the period’s net income and dividends to that permanent equity account. In a simple case with no other retained-earnings adjustments, the ending balance is the beginning balance plus net income less dividends. A net loss reduces retained earnings because it is negative net income.
This relationship follows from the closing entries. Closing revenue and expense accounts transfers their net effect, net income or net loss, into retained earnings. Closing dividends transfers the dividend balance as a reduction of retained earnings. Therefore, the ending retained earnings balance reflects both the period’s operating result and the distributions to owners.
Preparing and Checking the List
A reliable preparation method is to start from the ledger balances after closing, not from the unadjusted balances at the beginning of the period. Then include only permanent accounts with nonzero balances, place each balance on its debit or credit side, and add both columns. The totals should agree because each journal entry records equal debits and credits, and posting those entries preserves that equality. Closing entries change which accounts hold the balances, but do not change the equality of total debits and credits.
Use ledger balances after the closing entries have been posted. An adjusted trial balance from before closing is not a post-closing trial balance.
Retain assets, liabilities, and equity accounts. Check that revenue, expense, and dividends balances are zero.
Record debits and credits in their respective columns. Include contra accounts on the side of their actual ledger balance.
Verify that total debits equal total credits, then consider whether the listed balances make sense as amounts carried into the next period.
Worked Examples
Worked Example: Building a Post-Closing Trial Balance
At year-end, a hypothetical business reports cash of $18,400 debit, accounts receivable of $12,600 debit, allowance for uncollectible accounts of $600 credit, supplies of $1,200 debit, equipment of $40,000 debit, and accumulated depreciation of $8,000 credit. It also has accounts payable of $7,500 credit, wages payable of $1,100 credit, notes payable of $15,000 credit, and common stock of $20,000 credit. Beginning retained earnings were $17,500, net income was $4,000, and dividends were $1,500. Prepare the post-closing balances and check the totals.
Method. First calculate ending retained earnings using the closing relationship:
The account’s ending balance is therefore $20,000 credit. Revenue, expenses, and dividends have been closed, so none has a nonzero balance in the post-closing list.
Debit total. Add the debit balances: cash $18,400, accounts receivable $12,600, supplies $1,200, and equipment $40,000.
Credit total. Add allowance $600, accumulated depreciation $8,000, accounts payable $7,500, wages payable $1,100, notes payable $15,000, common stock $20,000, and retained earnings $20,000.
Check. Debits and credits both equal $72,200. The allowance and accumulated depreciation remain as credit balances because they are permanent contra accounts. The temporary accounts are closed, and the permanent balances are ready to carry forward.
Common mistake avoided: Do not omit contra accounts just because they reduce assets, and do not add dividends to retained earnings. Dividends reduce the ending balance.
Worked Example: A Balanced List That Is Not Post-Closing
A hypothetical company’s proposed post-closing list shows cash $9,000 debit, inventory $6,000 debit, equipment $30,000 debit, accumulated depreciation $5,000 credit, accounts payable $4,000 credit, notes payable $10,000 credit, common stock $15,000 credit, retained earnings $11,000 credit, wages expense $2,000 debit, and service revenue $2,000 credit. Is the list a valid post-closing trial balance?
Method. First test the debit and credit totals. Debits are cash $9,000, inventory $6,000, equipment $30,000, and wages expense $2,000:
Credits are accumulated depreciation $5,000, accounts payable $4,000, notes payable $10,000, common stock $15,000, retained earnings $11,000, and service revenue $2,000:
The columns balance, but the list is not a valid post-closing trial balance. Wages expense and service revenue are temporary accounts and both still have nonzero balances. The equal amounts happen to make the list balance, but they do not establish that closing is complete. Both accounts should be zero after closing and would normally be omitted. The permanent accounts shown total $45,000 on each side once the two temporary balances are removed.
Check. The permanent account debits are $9,000 + $6,000 + $30,000 = $45,000. Permanent account credits are $5,000 + $4,000 + $10,000 + $15,000 + $11,000 = $45,000. Thus the permanent balances are in balance, but the proposed list includes unclosed temporary accounts.
Common mistake avoided: Treating equal debit and credit totals as proof that the list is post-closing. The account types and their balances must also be checked.
Worked Example: Carrying Adjusted Balances Forward
A hypothetical business has the following adjusted balances before closing: cash $25,000 debit, accounts receivable $9,000 debit, allowance for uncollectible accounts $1,000 credit, inventory $7,000 debit, prepaid insurance $2,000 debit, equipment $50,000 debit, accumulated depreciation $12,000 credit, accounts payable $8,000 credit, wages payable $3,000 credit, notes payable $20,000 credit, common stock $30,000 credit, and beginning retained earnings $16,000 credit. Its temporary balances are revenue $24,000 credit, cost of goods sold $10,000 debit, wages expense $5,000 debit, depreciation expense $3,000 debit, insurance expense $1,000 debit, and dividends $2,000 debit. Find the post-closing retained earnings and verify the post-closing totals.
Step 1: Calculate net income. Add the expenses: $10,000 + $5,000 + $3,000 + $1,000 = $19,000. Subtract expenses from revenue:
Net income is $5,000. The ending retained earnings balance is:
Step 2: Add post-closing debits. The remaining debit balances are cash, accounts receivable, inventory, prepaid insurance, and equipment:
Step 3: Add post-closing credits. The remaining credit balances are allowance $1,000, accumulated depreciation $12,000, accounts payable $8,000, wages payable $3,000, notes payable $20,000, common stock $30,000, and retained earnings $19,000:
Check. Both post-closing columns total $93,000. Revenue, all four expenses, and dividends have zero balances after closing. The permanent account balances remain in the ledger for the next period.
Common mistake avoided: Carrying forward the adjusted trial balance unchanged. It includes temporary balances; the post-closing list instead reflects their transfer through the closing process.
What a Balanced Post-Closing Trial Balance Can and Cannot Tell You
Equal debit and credit totals are an arithmetic check on the ledger. They do not establish that every transaction was recorded, that it was recorded in the correct account, or that a closing entry was made to the correct permanent account. A list can balance while containing an omitted transaction, a misclassification, or equal nonzero temporary balances. The earlier material on errors a balanced trial balance cannot detect explains this limitation more broadly.
A useful final review therefore asks more than whether the columns agree:
- Were the balances taken after closing entries were posted?
- Are all nonzero accounts permanent accounts?
- Are revenue, expense, and dividends accounts zero?
- Does retained earnings reflect net income or loss and dividends?
- Do debit and credit totals agree?
These checks connect the close to the next period’s accounting records. Permanent balances continue forward, while temporary accounts begin the new period with no prior-period balance. This makes the post-closing trial balance a concise control over both the arithmetic of the ledger and the completion of closing.
Check Your Understanding
For each problem, identify the relevant permanent and temporary balances before checking the final result.
- A business begins the year with retained earnings of $28,400, earns net income of $6,750, and declares dividends of $1,200. What retained earnings balance should appear after closing? (Answer: $33,950 credit.)
- A proposed post-closing list includes $1,800 debit in wages expense and $1,800 credit in service revenue, along with permanent accounts whose debit and credit totals are equal. Is the list a valid post-closing trial balance, and what must be true of those two temporary accounts after closing? (Answer: No; wages expense and service revenue should each have zero balances.)
- A post-closing list shows cash $11,000 debit, accounts receivable $5,000 debit, equipment $20,000 debit, accumulated depreciation $3,000 credit, accounts payable $4,000 credit, notes payable $9,000 credit, common stock $12,000 credit, and retained earnings $8,000 credit. Find the debit total, credit total, and equipment’s net carrying amount after accumulated depreciation. (Answer: Debits $36,000; credits $36,000; net equipment $17,000.)
- Beginning retained earnings were $2,500; net income was $1,000; and dividends were $500. The permanent balances after closing are cash $8,000 debit, supplies $2,000 debit, equipment $15,000 debit, accumulated depreciation $4,000 credit, accounts payable $5,000 credit, notes payable $6,000 credit, and common stock $7,000 credit. Find ending retained earnings and verify the column totals. (Answer: Retained earnings $3,000 credit; debits and credits both $25,000.)
- A proposed list has permanent-account debits totaling $58,000 and permanent-account credits totaling $58,000. It also lists consulting revenue of $4,200 credit and rent expense of $4,200 debit. The preparer says the list is post-closing because the added amounts offset. Evaluate the claim and state what the proposed totals are. (Answer: The claim is incorrect because both temporary accounts remain nonzero; the proposed list totals are $62,200 debit and $62,200 credit.)
