The trial balance is the checkpoint between the bookkeeping and the financial statements, and it is widely trusted to do more than it does.
It confirms that entries were recorded in pairs. It says nothing about whether they were recorded correctly, which means a transaction posted to the wrong account, or omitted entirely, leaves it agreeing and wrong.
This covers what it shows, how it is structured, the difference before and after adjustments, the entries that typically change it, how it feeds the statements, what it cannot catch, and what happens between it and a signed set of accounts.
The trial balance is an internal accounting report that lists every general ledger account and its balance at a specific date. Total debits must equal total credits. It is a sanity check before preparing financial statements, not a financial statement itself.
What the Trial Balance Shows
- Every account in the chart of accounts with a non-zero balance
- Whether the books are mathematically balanced (debits = credits)
- The starting point for financial statement preparation
- Before adjusting entries: the unadjusted trial balance
- After adjusting entries: the adjusted trial balance (used to prepare statements)
A trial balance that agrees proves the entries were recorded in pairs. It proves nothing about whether they were recorded correctly. A transaction posted to the wrong account, or missed entirely, leaves it balanced and wrong.

Unadjusted vs Adjusted Trial Balance
| Type | When and What |
|---|---|
| Unadjusted Trial Balance | Pulled before month-end adjusting entries. Reflects only transactions posted from source documents. |
| Adjusted Trial Balance | After all adjusting entries: depreciation, prepaid amortisation, accruals, deferred revenue adjustments. |
| Post-Closing Trial Balance | After closing income/expense accounts to retained earnings at year end. Only balance sheet accounts remain. |
Common Adjusting Entries That Change the Trial Balance
- Depreciation: debit Depreciation Expense, credit Accumulated Depreciation
- Prepaid amortisation: debit Expense (insurance, rent), credit Prepaid Asset
- Accrued expenses: debit Expense, credit Accrued Liability (e.g., wages earned but not yet paid)
- Deferred revenue: debit Deferred Revenue, credit Revenue (for services performed)
- Inventory adjustment: debit or credit COGS to match physical count
Relationship to Financial Statements
| Trial Balance Accounts | Goes To |
|---|---|
| Revenue and Expense accounts | Income Statement (Profit and Loss) |
| Asset, Liability, and Equity accounts | Balance Sheet |
| Net Income (from P&L) | Flows to Retained Earnings on Balance Sheet |
What the Trial Balance Cannot Catch
- Transactions posted to the wrong account (e.g., rent expense coded to repairs, both are debits, balance still works)
- Transactions omitted entirely (no entry means no imbalance)
- A debit and credit of equal wrong amounts posted to the wrong accounts
- Errors of principle (capitalising an expense that should be expensed, or vice versa)
From Trial Balance to Signed Accounts
The trial balance is a checkpoint rather than a destination, and it helps to know what still has to happen between it and a set of accounts anybody else will rely on. The gap is larger than it looks.
First the adjustments that only make sense at the period end: costs paid in advance spread forward, costs incurred but not yet billed brought back, stock restated to the count, depreciation posted, and anything doubtful in the receivables provided against. Each of these changes the profit figure, which is why a trial balance that balances is not the same thing as a result you can report.
Then classification. The accounts group the ledger into the headings a reader expects, which means deciding what is an asset and what is a cost, what is current and what is not, and what has to be disclosed separately. Finally somebody has to take responsibility for the judgements inside those choices. That last step is the one that turns a working document into a statement somebody signs.
- Keep the adjustments as a listed set of journals rather than direct edits, so the route from ledger to accounts can be retraced
- Agree the stock, the bank and the debtor provision before anything is classified, because each changes the figures that follow
- Save the trial balance as it stood at the close, since it is the reference point if a figure is questioned later
- Expect the first version to move, and date every iteration so nobody works from a superseded copy

Frequently Asked Questions
Is the trial balance the same as the balance sheet?
No. The trial balance lists all accounts including income and expense accounts. The balance sheet shows only asset, liability, and equity accounts after income and expense accounts are closed.
What does it mean if the trial balance does not balance?
A debit/credit imbalance means there is a data entry error: a one-sided entry, a transposition error, or a math mistake. Modern accounting software prevents trial balance imbalances by enforcing double-entry rules at the transaction level.
How does a bookkeeper use the trial balance?
The bookkeeper pulls the trial balance before period close, reviews accounts for unusual balances (e.g., a credit balance in an asset account), posts adjusting entries, and then prepares the financial statements from the adjusted trial balance.
Who actually looks at this, and when?
Whoever closes the books, at the point of closing them, and then anyone preparing or reviewing the statements that come out of it. It is a working document rather than a report for an audience: nobody outside the finance process asks for one. Its value is that it puts every account on one page in one place, which makes an account with an implausible balance visible in a way it never is inside a finished statement.
What is worth checking on it every month?
The accounts that should be empty and are not. A suspense or holding account with a balance in it means something was posted without a home. A bank account whose balance does not match the statement means the reconciliation is unfinished. A balance with the wrong sign, such as a negative asset or a debit sitting on a supplier account, almost always means a transaction went to the wrong side. Those three checks catch most of what goes wrong.
