Limitations of the Trial Balance and Its Role in Financial Statements

Updated 11 October 2026 · Fact-checked

A trial balance lists every ledger balance and checks that total debits equal total credits. If it balances, the double entry is arithmetically consistent. It does not prove the accounts are correct, because many errors leave it balanced. You then use it as the starting point for the financial statements.

Understand Limitations of the Trial Balance and Its Role in Financial Statements

A trial balance is a list of all ledger account balances at a date, with debit balances in one column and credit balances in the other. Because every transaction has equal debits and credits, the two totals should agree.

A balanced trial balance tells you one thing: the total of debit balances equals the total of credit balances. That is all. It does not tell you the right accounts were used, the right amounts were recorded, or that every transaction was recorded at all.

Some errors leave the trial balance balanced. These include an error of omission (a transaction left out completely), an error of commission (right type of account, wrong account), an error of principle (wrong type of account, such as an asset expensed), an error of original entry (wrong amount entered on both sides), a reversal of entries (debit and credit swapped), and compensating errors (two errors that cancel out). Other errors cause an imbalance: a one-sided entry, different amounts on each side, or a balance added up wrongly or entered in the wrong column. A suspense account is used temporarily to make an unbalanced trial balance agree until the errors are found.

The trial balance is still very useful. It is the starting point for the financial statements. Income and expense balances go to the statement of profit or loss. Asset, liability and equity balances go to the statement of financial position. Period-end adjustments (accruals, prepayments, depreciation, closing inventory, irrecoverable debts) are applied first, because the unadjusted trial balance does not yet show the true position.

Key formulas to remember

Trial balance check: Total debit balances = Total credit balances; Balancing shows arithmetic consistency of the double entry only. It does not prove the accounts are accurate.
Errors that do not affect the trial balance: Omission, commission, principle, original entry, reversal, compensating; Debits still equal credits, so the trial balance balances and the error stays hidden.
Suspense account balance: Suspense = difference between total debits and total credits; A debit total lower than the credit total needs a debit in suspense. A credit total lower needs a credit in suspense.
Accounting equation: Assets = Capital + Liabilities; Statement of financial position items come from the trial balance after adjustments.
Profit: Profit = Income − Expenses; Use adjusted income and expense balances from the trial balance.
Gross profit: Gross profit = Revenue − Cost of sales; Cost of sales = Opening inventory + Purchases − Closing inventory (with carriage inwards and returns adjusted).

How to solve Limitations of the Trial Balance and Its Role in Financial Statements questions

Use this method for questions on what a trial balance shows, and for questions that take you from a trial balance to the financial statements.

1Read the question to see whether it asks about a limitation, an error type or preparing a statement.
2For error questions, check whether the debit and credit effects are still equal. If equal, the trial balance still balances. If not, it will not balance.
3Name the error type if asked: omission, commission, principle, original entry, reversal, compensating.
4For an imbalance, work out the difference and its direction, then decide the suspense account entry.
5For preparation questions, list each balance and mark it as profit or loss item or financial position item.
6Apply the adjustments given (closing inventory, depreciation, accruals, prepayments) to both the affected statement and the balance.
7Build the statement of profit or loss first, then the statement of financial position using the profit figure in equity.
8Check that assets equal equity plus liabilities.

Quickest way: Balance test and sorting by statement

When to use it: Use when you have little time on multiple choice or number entry questions on errors or on extracting figures from a trial balance.

Ask: does the error affect one side only, or both sides equally? Both equally means the trial balance still balances.
For a wrong-amount error, check whether the same wrong amount was posted to the debit and the credit.
For an imbalance, subtract the smaller total from the larger. The side with the smaller total gets the suspense balance.
When extracting figures, ask: is it income or expense, or asset, liability or equity? Sort before you calculate.
Adjust only the balances named in the question, then do a quick check that assets equal equity plus liabilities.

Common mistakes in Limitations of the Trial Balance and Its Role in Financial Statements

Saying a balanced trial balance proves the accounts are correct.
Balancing feels like a final check, so students overstate it.
Fix: Say it proves only that total debits equal total credits. Errors of omission, commission, principle and others can remain.
Treating a reversal of entries as an error that unbalances the trial balance.
The debit and credit look wrong, so students assume the totals differ.
Fix: A reversal swaps both sides by the same amount, so totals still agree. Only one-sided or unequal entries cause an imbalance.
Putting the suspense balance on the wrong side.
Students guess the side instead of comparing totals.
Fix: Find which column is lower. The suspense balance goes there to make the totals equal.
Confusing error of commission with error of principle.
Both involve a wrong account.
Fix: Commission means the wrong account of the same type. Principle means the wrong type, such as capital expenditure treated as an expense.
Using unadjusted trial balance figures in the financial statements.
Students copy the figures straight across.
Fix: Apply closing inventory, depreciation, accruals, prepayments and irrecoverable debts before finalising each statement.
Omitting profit from equity in the statement of financial position.
Students prepare the two statements separately.
Fix: Add the profit for the year to retained earnings so the statement of financial position balances.

Worked examples

Example 1

A trial balance has total debits of $245,600 and total credits of $243,900. State the suspense account entry needed and the balance.

Show the solution

Find the difference: 245,600 − 243,900 = 1,700.
Credits are lower than debits, so a credit balance of $1,700 is needed to balance the trial balance.
Record the suspense account as a credit balance of $1,700.

Answer: Suspense account credit balance of $1,700.

Example 2

A trial balance shows these balances in $: Revenue 90,000; Opening inventory 8,000; Purchases 52,000; Wages 14,000; Rent 6,000. Closing inventory is $10,000. Calculate profit for the year.

Show the solution

Cost of sales = 8,000 + 52,000 − 10,000 = 50,000.
Gross profit = 90,000 − 50,000 = 40,000.
Expenses = 14,000 + 6,000 = 20,000.
Profit = 40,000 − 20,000 = 20,000.

Answer: Profit for the year is $20,000.

Exam tips

For "does the trial balance still balance?" questions, check whether the error changes debits and credits by equal amounts.
Learn the six error names and match them to a one-line example each.
Use the suspense side rule: the lower column gets the suspense balance.
In multiple response questions, select exactly the number of options stated.
In Section B, show adjusted figures separately so you can trace any slip.

Limitations of the Trial Balance and Its Role in Financial Statements: frequently asked questions

Does a balanced trial balance prove the accounts are accurate?

No. It proves only that total debits equal total credits. Errors such as omission, commission, principle, original entry, reversal and compensating errors can still exist.

What errors does a trial balance not reveal?

It does not reveal omission, commission, principle, original entry, reversal of entries or compensating errors. In each case debits and credits remain equal.

How is a trial balance used to prepare financial statements?

You sort each balance into the statement of profit or loss or the statement of financial position. You apply period-end adjustments first. Then you prepare the statements and check they balance.

What is a suspense account?

A suspense account is a temporary account used to make an unbalanced trial balance agree until the errors are found and corrected. Its balance should be cleared to nil once all errors are corrected.
