Journal Entries

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

The journal is the book of original entry — every transaction is recorded here first before being posted to the ledger. A journal entry must follow the double-entry principle: for every debit entry, there must be a corresponding credit entry of equal value. The basic rule is: debit what comes in, credit what goes out; debit all expenses and losses, credit all incomes and gains; debit the receiver, credit the giver.

The format of a journal entry includes: date, account titles, folio (ledger page number), narrative description (the “why” of the transaction), debit amount, and credit amount. The narrative is crucial — it explains the transaction and must be meaningful. “Cash a/c dr. To Capital a/c” is poor; “Cash received from Ada as initial capital contribution, receipt no. 001” is proper.

Standard Journal Entries — Common ICAN Transactions:

Transaction	Debit	Credit
Purchase of goods for cash	Purchases a/c	Cash a/c
Sale of goods on credit	Debtors (Sundry Debtors) a/c	Sales a/c
Purchase of fixed asset	Fixed Asset a/c	Cash/Bank a/c
Payment of rent	Rent a/c	Cash/Bank a/c
Receipt of commission	Bank a/c	Commission Received a/c
Withdrawal by proprietor	Drawings a/c	Cash a/c

⚡ Exam Tip: ICAN examiners penalise candidates who omit the narration. A journal entry without a narration typically earns only half marks. Write narrations as complete business explanations, not just “being…” statements.

The Journal and Its Role in the Accounting Cycle

The accounting cycle begins with identification of transactions, continues through recording in the journal, posting to ledger accounts, preparing a trial balance, and ends with the preparation of financial statements. The journal is therefore the connecting link between identification and classification. Under the double-entry system, every transaction is analysed into its debit and credit aspects before entry.

Compound Journal Entries

A compound journal entry combines multiple debits or credits in a single entry. For example, when a business pays rent of ₦25,000 and wages of ₦15,000 by cash:

• Rent a/c Dr. ₦25,000
• Wages a/c Dr. ₦15,000
• To Cash a/c ₦40,000

Purchases and Sales on Credit

The classification between cash and credit transactions is important:

• Cash purchases: Dr. Purchases a/c, Cr. Cash/Bank a/c
• Credit purchases: Dr. Purchases a/c, Cr. Sundry Creditors a/c
• Cash sales: Dr. Cash/Bank a/c, Cr. Sales a/c
• Credit sales: Dr. Sundry Debtors a/c, Cr. Sales a/c

Returns and Returns Inward/Outward

When goods are returned:

• Returns Inward (sales returns): Dr. Returns Inward a/c, Cr. Sundry Debtors a/c
• Returns Outward (purchase returns): Dr. Sundry Creditors a/c, Cr. Returns Outward a/c

Note that Returns Inward is an expense (reduces gross profit) while Returns Outward is income (reduces cost of purchases).

Bank Transactions

Modern practice distinguishes between:

• Cash book (kept as a separate journal-book) — receipts and payments
• Bank transactions in the general journal — only adjustments like bank charges, interest earned, direct deposits

Examples of general journal entries for bank adjustments:

• Bank charges: Dr. Bank Charges a/c, Cr. Bank a/c
• Interest earned (credit): Dr. Bank a/c, Cr. Interest Received a/c
• Dishonoured cheque: Dr. Debtor a/c, Cr. Bank a/c

Bad Debts

When a specific debtor is identified as uncollectible:

• Dr. Bad Debts a/c, Cr. Sundry Debtors a/c (writes off the debt)

If a provision for doubtful debts exists, the entry to write off is:

• Dr. Provision for Doubtful Debts a/c, Cr. Sundry Debtors a/c

Later, if the debt is recovered:

• Dr. Cash/Bank a/c, Cr. Bad Debts Recovered a/c (income)

⚡ Common Mistakes: Confusing Returns Inward with Returns Outward (one reduces sales, one reduces purchases/cost), and omitting to post the folio number which makes cross-referencing difficult.

Analytical Approach to Transaction Analysis

Every transaction analysis follows a four-step process:

1. Identify the two (or more) accounts affected
2. Classify each account as asset, liability, capital, income, or expense
3. Determine whether each account increases or decreases
4. Apply the rules of debit and credit

Rules of Debit and Credit:

Account Type	Debit Effect	Credit Effect
Assets	Increase	Decrease
Liabilities	Decrease	Increase
Capital	Decrease	Increase
Income/Revenue	Decrease	Increase
Expenses/Losses	Increase	Decrease

The accounting equation underpins everything: Assets = Capital + Liabilities. Any debit must equal any credit in every entry. A useful mental check: after a journal entry, re-read the narrative and ask whether the accounts move in a direction consistent with the transaction described.

Opening Entries

At the start of a new accounting period, an opening entry brings forward the closing balances from the previous period’s balance sheet:

• All assets: Dr. respective asset accounts, Cr. Opening Balance (or Suspense) a/c
• All liabilities: Dr. Opening Balance (or Suspense) a/c, Cr. respective liability accounts
• Capital: Dr. Opening Balance (or Suspense) a/c, Cr. Capital a/c

Imprest System for Petty Cash

Under the imprest system, a fixed amount (e.g., ₦50,000) is given to a petty cashier. As expenses are incurred, the petty cashier presents receipts and receives cash to replenish the fund back to the imprest amount. The journal entry for the initial advance:

• Dr. Petty Cash a/c ₦50,000, Cr. Bank a/c ₦50,000

Replenishment (say ₦12,000 spent on various items):

• Dr. Various expense accounts (postage ₦2,000, transport ₦4,000, stationery ₦6,000) = ₦12,000
• Cr. Bank a/c ₦12,000

Bad Debts and Provision for Doubtful Debts (IAS 37 / IFRS 9)

IFRS 9 (financial instruments) requires expected credit loss (ECL) modelling. Under the simplified approach for trade receivables, the provision is based on lifetime expected losses. However, many Nigerian SMEs continue to use the prescriptive method permitted in old standards.

Discounts

Trade discount is a percentage reduction in the catalogue/invoice price for bulk or trade customers — recorded at the net amount (after trade discount), not separately in the books. For example, list price ₦100,000, 20% trade discount → record ₦80,000.

Cash discount is offered for early payment — it is an expense/income to the buyer/seller respectively. For the buyer, taking a 5% cash discount on ₦80,000 = ₦4,000 discount received:

• Dr. Sundry Creditors ₦80,000, Cr. Bank ₦76,000, Cr. Discount Received ₦4,000

For the seller, allowing the discount:

• Dr. Cash ₦76,000, Dr. Discount Allowed ₦4,000, Cr. Sundry Debtors ₦80,000

Capital vs. Revenue Expenditure

This distinction determines whether spending is recorded as an asset (capital) or expensed immediately (revenue):

• Repainting a delivery van: Revenue (maintenance) → Dr. Repairs a/c
• Engine replacement (extending useful life): Capital → Dr. Van a/c
• Legal fees to acquire land: Capital → Dr. Land a/c
• Legal fees for defending a contract dispute: Revenue → Dr. Legal Expenses a/c

Suspense Account

When the trial balance fails to agree, the difference is temporarily placed in a Suspense Account. Common causes include: posting the wrong amount, omitting an amount, posting to the wrong side, or error of principle. Once the error(s) are located, the suspense account is cleared.

⚡ ICAN Exam Pattern: Journal entry questions are tested in both the Financial Accounting (Foundation) and Advanced Financial Accounting papers. Candidates must be able to produce correct journal entries with narrations for 10-15 transactions within a limited time. Practice past questions under timed conditions — ICAN typically allows 15 minutes for 10 journal entries.
