5.2 Prepare a Post-Closing Trial Balance

Post-Closing Trial Balance

The post-closing trial balance is the final step in the accounting cycle. Its job is to confirm that all closing entries were recorded correctly and that debits still equal credits after the books have been closed. Only permanent accounts appear on it, which means it also serves as the starting point for the next accounting period.

Preparing a Post-Closing Trial Balance

Before you prepare this trial balance, all closing entries should already be journalized and posted to the general ledger. Revenue, expense, and dividend accounts should have zero balances at this point. From there, the process is straightforward:

1. Go through the general ledger and identify every account that still has a balance.
2. List those accounts in a trial balance format with debit balances in the left column and credit balances in the right column.
3. Total both columns.
4. Compare the totals. If debits equal credits, your closing entries were recorded correctly.

Equal totals also confirm that the accounting equation is in balance: $\text{Assets} = \text{Liabilities} + \text{Owner's Equity}$

Which Accounts Appear (and Which Don't)

The post-closing trial balance includes only permanent (real) accounts, meaning accounts whose balances carry forward into the next period:

• Assets — cash, accounts receivable, inventory, prepaid expenses, equipment, etc.
• Liabilities — accounts payable, notes payable, accrued expenses, unearned revenue, etc.
• Equity — common stock and retained earnings

It excludes all temporary (nominal) accounts. These are the accounts that were closed to retained earnings during the closing process:

• Revenues
• Expenses
• Dividends (or owner's drawings)

If any of these temporary accounts show up with a balance on your post-closing trial balance, that's a clear sign something went wrong during closing.

Using It to Detect Errors

The post-closing trial balance catches two main types of problems:

• Unequal debit and credit totals — This points to an error in recording or posting closing entries. Common causes include skipped closing entries, transposed numbers, or posting to the wrong side of an account.
• Temporary accounts still carrying balances — If you see a revenue or expense account with a remaining balance, that account wasn't properly closed. Go back and check your closing entries.

Once the post-closing trial balance is verified, every permanent account has a correct beginning balance for the new fiscal period. Think of it as a clean, confirmed starting point. Accurate opening balances here are what make the next period's financial statements reliable from day one.
