Errors of Principle: The "Wrong Box" Mistake
Think of your home. You have a drawer for socks, a shelf for books, and a cupboard for dishes. Now imagine you come home tired and throw your socks into the book shelf. The socks are still in the house — nothing is lost — but they are in the wrong place. When you need socks, you will look in the drawer and find nothing. The system breaks.
That is exactly what an error of principle is in accounting.
The Precise Meaning
An error of principle occurs when a transaction is recorded in the wrong class of account. In accounting, every transaction must be classified as either:
- A personal account (for people, firms, banks)
- A real account (for assets, property, goods)
- A nominal account (for expenses, incomes, gains, losses)
When you debit or credit the wrong type of account — for example, treating a capital expense as a revenue expense — you have committed an error of principle.
The key test: Did you violate the fundamental rules of debit and credit for that class of account? If yes, it is an error of principle. If you simply put the right amount in the wrong account within the same class, it is a clerical error (error of commission), not an error of principle.
Why It Matters
Errors of principle do not affect the trial balance. The trial balance will still tally because the double entry is complete — one debit, one credit — but both entries are in the wrong kind of account. This means:
- The profit figure in the Profit & Loss Account will be wrong.
- The Balance Sheet will show incorrect assets or liabilities.
- Financial statements become misleading.
For example, if you buy a computer (an asset that will last years) and record it as "Office Expenses" (a revenue expense), the profit is understated in the current year and the asset never appears on the Balance Sheet. The business looks poorer than it really is.
Accounting Treatment: How to Correct It
The correction of an error of principle requires reversing the wrong entry and passing the correct entry. The general rule is:
- Remove the wrong effect by reversing the incorrect debit/credit.
- Record the correct debit/credit.
Let us take a concrete example.
Example: A business buys furniture for ₹50,000 and records it as "Purchases" (which is meant for goods bought for resale).
-
Wrong entry passed:
Purchases A/c Dr. ₹50,000
To Cash/Bank A/c ₹50,000
-
What should have been:
Furniture A/c Dr. ₹50,000
To Cash/Bank A/c ₹50,000
Correction entry:
| Date | Particulars | L.F. | Debit (₹) | Credit (₹) |
|---|---|---|---|---|
| Furniture A/c Dr. | 50,000 | |||
| To Purchases A/c | 50,000 | |||
| (Being error of principle corrected — furniture wrongly debited to purchases account now rectified) |
Why this works:
- Furniture A/c (a real account) should have been debited — we now debit it.
- Purchases A/c (a nominal account) was wrongly debited — we credit it to cancel that wrong debit.
- Cash/Bank was correctly credited in both entries, so no change is needed there.
A Second Example: Revenue vs. Capital Expenditure
This is the most common error of principle in exams.
Scenario: A company spends ₹20,000 on repairing an old machine (revenue expenditure — debited to Repairs A/c). But the same amount was spent on installing a new machine (capital expenditure — should be debited to Machinery A/c). The accountant wrongly debited Repairs A/c for the installation cost.
Correction entry:
| Date | Particulars | L.F. | Debit (₹) | Credit (₹) |
|---|---|---|---|---|
| Machinery A/c Dr. | 20,000 | |||
| To Repairs A/c | 20,000 | |||
| (Being capital expenditure wrongly treated as revenue expenditure — now rectified) |
A common mistake: students think they need to credit Cash again. Do not. Cash was correctly credited at the time of payment. Only the classification of the debit side was wrong. The correction entry only touches the two accounts that were misclassified.

Error of principle = recording a transaction against accounting principles (e.g. capital treated as revenue).
An error of principle occurs when a transaction is recorded in a way that violates the basic accounting principles - typically when a capital item is treated as a revenue item or vice versa (e.g. purchase of machinery debited to Purchases A/c, or repairs debited to the asset account). Since both the debit and credit are recorded (only in a wrong head), the trial balance still agrees, so i …

›Reveal solutionSolution
Recording purchase of furniture in Purchase A/c is an Error of Principle (capital vs revenue expenditure misclassification).
An Error of Principle occurs when a transaction is recorded in violation of a fundamental accounting rule, typically by confusing capital expenditure with revenue expenditure. Furniture is a fixed asset, so buying it is capital expenditure to be debited to Furniture A/c. Debiting it to Purchase A/c wrongly treats it as goods bought for resale (revenue expenditure).

- CBSE 2018Set ANNUAL1 markQ.Give an example of error of principle. Or What is Error of Omission?
›Reveal solutionSolution
Error of principle: treating capital expenditure as revenue (e.g. machinery debited to Purchases). (Or) Error of omission: a transaction is not recorded at all or only partly recorded.
Example of error of principle: Wages paid for installation of a new machine (capital expenditure) debited to Wages A/c (a revenue expense), or purchase of furniture debited to Purchases A/c. Here a fundamental accounting principle — the distinction between capital and revenue items — has been violated. Such errors do not affect the agreement of the Trial Balance.
