Trial Balance: A Statement, Not an Account
A trial balance is a statement showing the balances (or totals) of all the accounts in the ledger, prepared to verify the arithmetical accuracy of posting into the ledger (NCERT, p. 180).
It is not a ledger account: an account records the transactions of one head of account, whereas the trial balance merely lists, in one place, the final position of every account in the ledger. Because it is a statement, it is never itself debited or credited — you cannot “make an entry” in it.
The trial balance is usually prepared with the balances of accounts rather than their totals, at the end of an accounting year — or at any interval the business chooses: monthly, quarterly, half-yearly or annually (NCERT, p. 181).
The steps of preparation are (NCERT, p. 181):
- Ascertain the balance of each account in the ledger.
- List each account and place its balance in the debit or credit column; a zero-balance account may appear with zero in its normal column.
- Total the debit balance column.
- Total the credit balance column.
- Verify that the two totals are equal; if they are not, errors exist and must be located.
Fig. 6.1 shows the standard format: the heading “Trial Balance of … as on [date]”, then columns for Account Title, L.F. (ledger folio), Debit Balance ₹ and Credit Balance ₹, with the two money columns totalled at the bottom (NCERT, p. 181). Fig. 6.2 is an illustrative trial balance that shows which accounts normally appear on which side (NCERT, p. 182):
| Type of account | Normal balance | Examples |
|---|---|---|
| Assets | Debit | Land, Plant and Machinery, Furniture, Cash in Hand, Cash at Bank, Stock |
| Expenses | Debit | Purchases, Wages, Salaries, Carriage Inwards, Carriage Outwards, Interest Paid |
| Drawings | Debit | Drawings |
| Receivables and contra-revenue | Debit | Debtors, Bills Receivable; Sales Return |
| Liabilities | Credit | Creditors, Bills Payable, Long-Term Loan, Advances from Customers |
| Capital | Credit | Capital |
| Revenue and contra-expense | Credit | Sales, Commission/Discount Received; Purchases Return |
The chapter lists three objectives of preparing a trial balance (NCERT, pp. 181–183):
- To ascertain the arithmetical accuracy of the ledger accounts. As a summary of the ledger, a trial balance whose debit and credit totals are equal suggests that posting and balancing have been done correctly in arithmetic terms.
- To help in locating errors. A difference between the two totals is the first signal that at least one error exists.
- To help in the preparation of the financial statements. The trial balance is the connecting link between the ledger and the final accounts: revenue and expense accounts are transferred to the trading and profit and loss account, and assets, liabilities and capital to the balance sheet.
The crucial limitation: a tallied trial balance is not conclusive proof that the books are accurate. It only proves, to an extent, that posting is arithmetically correct. If the bookkeeper posts a correct amount to the wrong account, or records an equal debit and credit of a wrong amount, two accounts are wrong yet the trial balance still agrees.
To verify any format or illustration against the book itself, the official NCERT PDF of this chapter (keac106.pdf) is available on ncert.nic.in.
Three Methods of Preparing a Trial Balance
The textbook demonstrates all three methods on the same set of ledger accounts of Mr Rawat (NCERT, pp. 185–188); whichever method is used, the totals agree because the ledger follows double entry. The methods differ only in what is entered in the amount columns (NCERT, p. 184).
| Method | What goes into the amount columns | Used in practice? |
|---|---|---|
| Totals method | The total of the debit side and the total of the credit side of each ledger account | Rarely — it does not test the correctness of account balances and does not feed the financial statements |
| Balances method | The closing balance of each ledger account, debit or credit | Standard method — a balance summarises the net effect of all transactions of that account and flows directly into the financial statements |
| Totals-cum-balances method | Four amount columns: debit total, credit total, debit balance, credit balance | Not used — time consuming and it serves no additional purpose |
The balances method dominates for a practical reason: one figure per account, ready to be lifted into the final statements. In this method, individual debtors’ accounts are normally combined into one sundry debtors figure and individual creditors’ accounts into one sundry creditors figure (NCERT, p. 184).
The totals method cannot offer that, which is why it survives mainly as a concept in the chapter.
Key Terms: The Four Types of Errors and the Suspense Account
Keeping in view the nature of errors, all errors are classified into four types (NCERT, pp. 189–190). The definitions below, with original examples, are the ones to memorise.
| Term | Student-friendly meaning | Example |
|---|---|---|
| Error of commission | A clerical slip in recording, posting, totalling (casting), carrying forward or balancing | Payment of ₹ 5,000 to a supplier posted to his account as ₹ 500 |
| Error of complete omission | A whole transaction is never entered in the books of original entry | Credit sales of ₹ 8,000 not entered in the sales book at all |
| Error of partial omission | A transaction is recorded, but one posting is skipped | Credit sales entered in the sales book, but the customer’s account was not debited |
| Error of principle | Violation of accounting principles, mainly wrong classification of capital and revenue items | ₹ 25,000 spent on extending a building debited to the maintenance and repairs account |
| Compensating errors | Two or more errors whose effects on debits and credits cancel each other out | Purchases book overcast by ₹ 2,000 (excess debit) and sales book overcast by ₹ 2,000 (excess credit) — net effect nil |
| Suspense account | The temporary account in which the trial balance difference is parked until the errors are found | Credit column of the trial balance exceeds debit column by ₹ 14,000; the ₹ 14,000 is entered as a debit-balance suspense account so the trial balance agrees |
The memory device COPS keeps the four error types in view: Commission, Omission, Principle, Compensating. When a problem names the type, COPS reminds you of the family; the next section tells you what that family does to the trial balance.
Real-life application. Accounts are closed on a schedule. When the trial balance refuses to tally, the accountant enters the difference in the suspense account, makes the trial balance agree, and keeps the accounting process moving.
The business can then prepare its final statements on schedule while the errors are still being located — suspense is the temporary plug that makes the deadline possible. It is not a real category of account; it is a stopgap that disappears once every located error is rectified.
Which Errors Affect the Trial Balance — and Which Slip Past It
The most useful skill in this chapter is instant classification: from the wording of an error, decide whether the trial balance will agree or disagree. The test is simple — does the error change only one side of the double entry, or both sides equally?
| Category | Examples | Effect on the trial balance |
|---|---|---|
| One-sided errors (affect the agreement) | A posting not made at all; posting to the correct account with the wrong amount; posting on the wrong side; wrong casting of a subsidiary book; error of carrying forward; error of balancing; an account balance omitted from the trial balance; error in totalling the trial balance’s own columns | Trial balance will NOT tally, because only one side of the double entry is wrong |
| Two-sided errors (do not affect the agreement) | Complete omission of a transaction; a correct amount posted to the wrong account; an equal wrong amount on both debit and credit; errors of principle; compensating errors | Trial balance still tallies, because both sides are equally wrong |
Work through the logic once with a pair of examples. Sales return book overcast by ₹ 300: sales returns is a debit-balance account, so the excess lies in one account — one-sided — the trial balance will not tally.
Rent of ₹ 4,000 paid but debited to the landlord’s personal account: the rent account is short and the landlord’s account is wrongly debited — two accounts are wrong and the totals still agree — two-sided.
So a tallied trial balance is a necessary check but not a sufficient one: it proves that posting is arithmetically correct, yet it does not guarantee that every entry itself is correct.
How to Locate a Difference: Divide-by-2 and Divide-by-9 Shortcuts
When the trial balance does not tally, work systematically in this order (NCERT, p. 191):
- Recast the totals of the debit and credit columns of the trial balance.
- Compare each account title and amount in the trial balance with the ledger, hunting for differences or omissions.
- Compare the current year’s trial balance with the previous year’s to spot unexpected additions, deletions or large unexplained changes.
- Recompute the balances of individual accounts in the ledger.
- Re-check the postings from the books of original entry into the ledger accounts.
Two mathematical shortcuts cut the search time:
- Difference divisible by 2. Half the difference may have been posted to the wrong side. Example: the debit column exceeds the credit column by ₹ 2,600 — a credit item of ₹ 1,300 may have been posted as a debit, because the debit gains 1,300 and the credit loses 1,300, giving 2 × 1,300 = ₹ 2,600. Scan the debits of ₹ 1,300. The whole difference may also be a posting of ₹ 2,600 omitted from one side, so scan for that amount too.
- Difference divisible by 9. Transposition of figures is likely: ₹ 372 posted as ₹ 723 differs by ₹ 351, which is 39 × 9. A wrongly placed decimal point behaves the same way — ₹ 1,240 posted as ₹ 124 differs by ₹ 1,116, which is 124 × 9. The reason: moving a digit from one place to another changes a number by a multiple of 9.
These shortcuts do not identify the wrong item; they narrow the suspects to amounts you should search for.
The Working Rule That Acts as the Chapter’s Formula
Rectification has one rule, and every entry in the chapter follows it (NCERT, p. 192):
If an account has a short debit or an excess credit, debit it. If it has an excess debit or a short credit, credit it.
| Situation in the account | Action to take |
|---|---|
| Short debit | Debit the account |
| Excess credit | Debit the account |
| Excess debit | Credit the account |
| Short credit | Credit the account |
Why this works: every rectification must (1) cancel the wrong effect already recorded and (2) restore the correct effect. Debiting an account with a short debit gives it what it lacked; debiting an account with an excess credit removes the excess credit that must go — in both cases the debit is the correcting motion.
The rule is identical whether suspense is involved or not. Suspense only changes the second account of the entry: for a two-sided error the second account is the other real account; for a one-sided error it is the suspense account.
Two-Sided Errors: Rectifying Without Suspense
A two-sided error is one in which both the debit and credit effects are wrong. Because both effects are known, a single journal entry between the two real accounts rectifies it — no suspense needed. Complete omissions, wrong recordings, errors of principle, and postings to the wrong account on the correct side all belong here.
Worked example — a sales entry recorded for the wrong amount
Step 1 — Classify.
Credit sales to Kavita of ₹ 18,000 were recorded in the sales book as ₹ 1,800.
The recording is wrong, so both accounts carry wrong figures: Kavita’s account is short and the sales account is short — an error of commission, two-sided.
Step 2 — Write the wrong effect.
Kavita’s A/c Dr.
₹ 1,800 and Sales A/c Cr.
₹ 1,800, instead of ₹ 18,000 each.
Step 3 — Write the correct effect.
Kavita’s A/c Dr.
₹ 18,000 and Sales A/c Cr.
₹ 18,000.
Step 4 — Apply the rule.
Kavita’s account has a short debit of ₹ 16,200 → debit it.
Sales has a short credit of ₹ 16,200 → credit it.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Kavita’s A/c | Dr. | 16,200 | |
| To Sales A/c | 16,200 | ||
| (Credit sales to Kavita recorded as ₹ 1,800 instead of ₹ 18,000, now corrected.) | |||
Rectification entry: Kavita’s A/c Dr ₹ 16,200; To Sales A/c ₹ 16,200. The narration tells the reader which error is being corrected.
The same cancel-and-restore logic handles an error of principle: furniture bought for ₹ 11,000 was debited to the purchases account. Purchases has an excess debit of ₹ 11,000 → credit it; Furniture has a short debit → debit it:
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Furniture A/c | Dr. | 11,000 | |
| To Purchases A/c | 11,000 | ||
| (Furniture purchased, wrongly debited to purchases account, now corrected.) | |||
A complete omission is also two-sided — neither debit nor credit exists. Credit sales of ₹ 10,000 to Meera never entered in the sales book are rectified by passing the original entry itself: Meera’s A/c Dr ₹ 10,000; To Sales A/c ₹ 10,000.
One-Sided Errors: Bringing in the Suspense Account
A one-sided error makes only one account wrong; the other side of the double entry is correctly recorded.
Examples: a posting not made at all, a posting with the wrong amount, a posting on the wrong side, a casting error in a subsidiary book, an error of carrying forward or balancing, and an account balance omitted from the trial balance (NCERT, p. 196).
Because only one account is wrong, the trial balance cannot agree, and a journal entry between two real accounts is impossible without a placeholder for the missing effect. That placeholder is the suspense account.
The textbook gives a five-step procedure (NCERT, p. 199):
- Identify the account affected by the error.
- Ascertain the amount of the excess debit, excess credit, short debit or short credit in that account.
- If the account has an excess debit or a short credit, credit the account with that amount.
- If the account has an excess credit or a short debit, debit the account with that amount.
- Complete the entry by putting the same amount on the opposite side of the suspense account.
| One-sided error | Effect on the affected account | Rectification entry |
|---|---|---|
| Credit sales to Anil ₹ 9,000 not posted to his account | Anil’s A/c — short debit ₹ 9,000 | Anil’s A/c Dr ₹ 9,000; To Suspense A/c ₹ 9,000 |
| Credit sales to Anil ₹ 9,000 posted to his account as ₹ 7,000 | Anil’s A/c — short debit ₹ 2,000 | Anil’s A/c Dr ₹ 2,000; To Suspense A/c ₹ 2,000 |
| Credit sales to Anil ₹ 9,000 posted to his account as ₹ 10,000 | Anil’s A/c — excess debit ₹ 1,000 | Suspense A/c Dr ₹ 1,000; To Anil’s A/c ₹ 1,000 |
| Purchases book overcast by ₹ 2,000 | Purchases A/c — excess debit ₹ 2,000 | Suspense A/c Dr ₹ 2,000; To Purchases A/c ₹ 2,000 |
| Purchases book undercast by ₹ 1,000 | Purchases A/c — short debit ₹ 1,000 | Purchases A/c Dr ₹ 1,000; To Suspense A/c ₹ 1,000 |
The direction follows a single pattern: when the affected account is debited, credit suspense; when the affected account is credited, debit suspense. Suspense is simply the other side of the same entry.
What if the suspense account refuses to balance off? That happens when some errors remain undiscovered. The suspense account is then not closed; its remaining balance is carried forward to the next accounting year and is eliminated as and when the remaining errors are located (NCERT, p. 212).
If the located errors belong to the previous year’s books, the rectifications use the profit and loss adjustment account in place of the expense or income accounts, so that the new year’s income statement is not distorted (NCERT, p. 202) — a detail you will meet at an advanced stage.
Worked Examples: Error → Entry → Suspense Account
Three examples in increasing difficulty. In each: classify → write the wrong effect → apply the rule → record the entry with narration.
Example 1: Two-sided error — no suspense
Error: Furniture costing ₹ 11,000 was debited to the purchases account.
Step 1 — Classify.
Furniture is an asset, so the debit belongs in Furniture A/c.
Debiting purchases instead violates the capital–revenue split — an error of principle, two-sided.
Step 2 — Wrong effect.
Purchases A/c Dr.
₹ 11,000, with cash or the creditor credited.
Step 3 — Correct effect.
Furniture A/c Dr.
₹ 11,000.
Step 4 — Apply the rule.
Purchases has an excess debit → credit it; Furniture has a short debit → debit it.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Furniture A/c | Dr. | 11,000 | |
| To Purchases A/c | 11,000 | ||
| (Furniture purchased, wrongly debited to purchases account, now corrected.) | |||
Rectification entry: Furniture A/c Dr ₹ 11,000; To Purchases A/c ₹ 11,000.
Example 2: One-sided error — suspense is used
Error: Credit sales to Kavita of ₹ 18,000 were not posted to her account. The sales book itself is correct, so the sales account credit is already there.
Step 1 — Classify.
Recording is correct; only the posting to Kavita’s account is missing — partial omission, one-sided.
Step 2 — Wrong effect.
No debit in Kavita’s account; Sales A/c is correctly credited through the sales book total.
Step 3 — Apply the rule.
Kavita’s account has a short debit of ₹ 18,000 → debit it, and complete the entry by crediting suspense.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Kavita’s A/c | Dr. | 18,000 | |
| To Suspense A/c | 18,000 | ||
| (Credit sales to Kavita not posted to her account, now rectified.) | |||
Rectification entry: Kavita’s A/c Dr ₹ 18,000; To Suspense A/c ₹ 18,000.
Example 3: Three errors — a suspense account that closes
Situation: A trial balance showed excess credit of ₹ 14,000. The difference was placed in a suspense account, which therefore appears with a debit balance of ₹ 14,000. The accountant later located three errors:
- (a) Sales book overcast by ₹ 2,000.
- (b) Credit sales to Ritu of ₹ 9,000 not posted to her account.
- (c) Purchases book undercast by ₹ 3,000.
Error (a).
An overcast sales book gives Sales A/c an excess credit of ₹ 2,000 → debit Sales A/c and credit suspense.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Sales A/c | Dr. | 2,000 | |
| To Suspense A/c | 2,000 | ||
| (Sales book overcast by ₹ 2,000, now corrected.) | |||
Error (b).
Ritu’s account is short by ₹ 9,000 on the debit side → debit Ritu’s A/c and credit suspense.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Ritu’s A/c | Dr. | 9,000 | |
| To Suspense A/c | 9,000 | ||
| (Credit sales to Ritu not posted to her account, now rectified.) | |||
Error (c).
An undercast purchases book leaves Purchases A/c short by ₹ 3,000 on the debit side → debit Purchases A/c and credit suspense.
| Particulars | L.F. | Debit ₹ | Credit ₹ |
|---|---|---|---|
| Purchases A/c | Dr. | 3,000 | |
| To Suspense A/c | 3,000 | ||
| (Purchases book undercast by ₹ 3,000, now corrected.) | |||
Now prepare the suspense account. It opened with the trial balance difference on its debit side, and each rectification credits it:
| Particulars | Amount ₹ | Particulars | Amount ₹ |
|---|---|---|---|
| Difference as per trial balance | 14,000 | Sales A/c | 2,000 |
| Ritu’s A/c | 9,000 | ||
| Purchases A/c | 3,000 | ||
| Total | 14,000 | Total | 14,000 |
The credit side totals 2,000 + 9,000 + 3,000 = ₹ 14,000, exactly cancelling the opening debit of ₹ 14,000. The suspense account closes, which tells you every one-sided error was found. Notice how the opening side was decided: the trial balance had an excess credit, so the difference was inserted on the shorter (debit) side — suspense therefore started with that debit.
The 11 Guiding Principles of Rectification, Simplified
Problems often stay silent about one detail — the side of a posting, or whether an amount was right. The textbook’s 11 guiding principles list what the accountant must assume in each silence (NCERT, pp. 202–203). They compress into six situations:
| When the problem says… | Assume… | Consequence for the entry |
|---|---|---|
| “Error in the books of original entry” | All postings were done accordingly | The wrong effect sits in the recording itself; the correction usually touches both accounts. |
| “Error at the posting stage” | Recording in the subsidiary books is correct | Only the posting side is wrong; the original books stand. |
| “Posted to the wrong account” (side and amount not mentioned) | Right side, right amount | Two accounts are involved; a transfer entry between them; no suspense. Example: credit purchases of ₹ 8,000 credited to the wrong supplier’s account. |
| “Correct account with a wrong amount” (side not mentioned) | Correct side | Only one account’s figure is wrong → rectified through suspense for the difference. |
| “Posted on the wrong side” (amount not mentioned) | Correct amount | The amount works twice — once to cancel the wrong side, once to restore the right side — so the rectification is double the amount, through suspense. Example: credit purchases of ₹ 9,000 posted to the debit of Rohan’s account → Suspense A/c Dr ₹ 18,000; To Rohan’s A/c ₹ 18,000. |
| Special book rules: casting error, cash book entry, journal proper | A casting error affects only the total account, not individual parties; a cash book error affects the other account, never cash; a journal-proper “not posted” affects both accounts | Casting errors are one-sided → suspense; cash is never corrected; journal-proper omissions need the original two-account entry without suspense. |
Two of these rules are worth memorising separately: an error in the total of a subsidiary book affects only the account where that total is posted (for example Purchases A/c or Sales A/c), never the individual parties; and an error connected with a cash book entry always concerns the other account — the cash or bank account is assumed correct.
Common Mistakes: What Students Write vs What Is Correct
| Mistake | Correct rule | Accounting reason — and how to check |
|---|---|---|
| Cash sales of ₹ 16,000 not posted to Sales A/c → enter Cash A/c Dr.; To Sales A/c | Suspense A/c Dr ₹ 16,000; To Sales A/c ₹ 16,000 | The cash book entry (Cash Dr ₹ 16,000; Sales Cr ₹ 16,000) has already been recorded; only the posting to Sales A/c is missing. Cash is not wrong — check that your rectification never touches an account the stem said was correct. |
| Opening a suspense account for a complete omission | No suspense; pass the original journal entry between the two real accounts | A complete omission means neither debit nor credit exists — both sides are wrong, so it is two-sided. Check: if your entry has two real accounts, no suspense belongs in it. |
| Sales return book overcast → Sales Return A/c Dr.; To Suspense A/c | Suspense A/c Dr.; To Sales Return A/c | Sales returns is a debit-balance account, so an overcast gives Sales Return A/c an excess debit. Remove the excess by crediting it; suspense must then be debited to keep the entry balanced. |
| Thinking errors of principle disturb the trial balance | They are two-sided — the trial balance still agrees | Wrong classification changes which account is debited, but total debits still equal total credits. Check: classify the item first (capital vs revenue), then decide. |
| Credit purchases of ₹ 9,000 posted to the debit of Rohan’s account → Suspense A/c Dr ₹ 9,000; To Rohan’s A/c ₹ 9,000 | Suspense A/c Dr ₹ 18,000; To Rohan’s A/c ₹ 18,000 | Rohan should be credited ₹ 9,000 yet shows a debit of ₹ 9,000. The correction needs ₹ 9,000 to cancel the wrong debit plus ₹ 9,000 to create the right credit. A wrong side always costs double the amount. |
| Reading “not recorded” as “not posted” | Not recorded = complete omission → two-sided, no suspense; not posted = partial omission → one-sided, suspense | The two phrases change the affected account and the whole entry. Check the stem’s exact words before writing anything. |
Exam Notes: How to Write a Complete Answer
Concept questions
The chapter’s short and long questions (NCERT, pp. 216–223) mostly ask you to state meanings, list objectives, give examples and explain error types.
A complete answer for “state the meaning of a trial balance” opens by naming it a statement, not an account; says it lists the balances (or totals) of all ledger accounts; and ends with its purpose — verifying the arithmetical accuracy of posting.
For “give two examples of errors of principle,” name the error, give a concrete transaction for each, and state that such errors do not affect the agreement of the trial balance.
Rectification entries
Always use the standard journal format — date, particulars, L.F. (if asked), debit and credit columns — and close every entry with a narration. When you are unsure, write the wrong effect and the correct effect first; the difference between them is the rectification. Use the suspense account only for one-sided errors.
Suspense account questions
The numerical questions of this chapter group into four families, and each family has its own complete-answer shape (NCERT, pp. 217–223):
- Recording-stage errors (not recorded, wrong amount recorded) → journal entry between the two real accounts; no suspense.
- Wrong account or wrong classification (salary debited to an employee’s personal account; furniture debited to purchases) → transfer entry between the two accounts.
- One-sided posting and casting errors (not posted, posted short or excess, wrong side, book overcast or undercast) → entry through suspense.
- Multi-error questions → rectify each error, then prepare the suspense account, opening it with “Difference as per trial balance” on the side matching the trial balance’s short side; post each rectification on the opposite side of the affected account; total and balance off, carrying forward any remainder.
Word-watch
Three word pairs decide the entry: “not recorded” vs “not posted,” “overcast” vs “undercast,” and “posted short” vs “posted excess.” Read the stem once for meaning before writing anything. The same one-sided-versus-two-sided logic recurs in the related Bank Reconciliation Statement notes, where a timing difference plays the role of the suspense difference.

FAQs: Trial Balance and Rectification Doubts
Can a trial balance tally even when the books contain errors?
Yes — and that is why the trial balance is only an arithmetic check. Two-sided errors — a complete omission, a correct amount posted to the wrong account, an equal wrong amount on both sides, errors of principle and compensating errors — leave total debits equal to total credits even though the books are wrong.
A tallied trial balance therefore does not prove accounting accuracy; it only checks posting arithmetic.
When should I use a suspense account in a rectification entry and when should I not?
Use suspense only for one-sided errors — those that affect one account and therefore disturb the agreement of the trial balance, such as a posting not made, a wrong amount in a posting, or a casting error.
Do not use suspense for two-sided errors such as complete omissions or errors of principle; those are rectified by a journal entry between the two real accounts.
How do I decide whether to debit or credit the suspense account?
Apply the main rule to the affected account first. If that account needs a debit (short debit or excess credit), complete the entry by crediting suspense. If it needs a credit (excess debit or short credit), debit suspense. Suspense always takes the side opposite to the affected account.
What does a trial balance difference divisible by 2 or 9 tell me about the error?
A difference divisible by 2 suggests that half the difference was posted to the wrong side — for example, a credit item of ₹ 1,300 posted as a debit creates a difference of ₹ 2,600. The whole difference could also be a posting omitted from one side. A difference divisible by 9 suggests transposition of figures (₹ 372 posted as ₹ 723 gives ₹ 351 = 39 × 9) or a wrongly placed decimal point.
What happens if the suspense account still has a balance after all located errors are rectified?
The remaining balance is carried forward to the next accounting year and is eliminated as and when the remaining errors are located.
When errors committed in one year are found in the next year, the profit and loss adjustment account is used in place of the expense or income accounts so that the next year’s income statement is not distorted — a treatment you will study at an advanced stage.
