Key Concepts
An income account records every transaction affecting that income during the financial period.
Each entry's Particulars column names the account on the other side of that double entry — the one where the matching debit or credit was posted. It tells you what each entry represents.
To interpret a ledger account:
- Identify each entry — what transaction does it represent? (Reversal, cash receipt, year-end adjustment, or closing entry?)
- Check for year-end adjustments — look for entries that set up or reverse income received in advance or income receivable balances.
- Find the income for the period — the amount transferred to Income summary via the closing entry is the income recognised for the year.
- Prepare financial statement extracts — any remaining balance for income received in advance or income receivable at year end appears in the Statement of Financial Position.
Read an income ledger account by when each entry appears:
- Start of year → reversals: a debit reverses the previous year's income receivable; a credit reverses the previous year's income received in advance
- At year end — adjustment (before closing) → a debit removes the unearned portion from income (recording it as income received in advance); a credit adds the earned-but-unreceived portion to income (recording it as income receivable)
- At year end — closing → closing entry to Income summary (debit), clears the balance to nil
Income earned for the period = the closing entry amount, not total cash received.

| 31 May | Rental income received in advance | 5,000 | 35,000 Cr | |
| 31 May | Income summary | 35,000 | — |
On 1 Jun 20X4, $4,000 of rental income earned in the previous period is reversed out of Rental income receivable, so that it is not double-counted in the current period.
On 31 May 20X5, $5,000 cash collected in the current period relates to rental income that will only be earned in the next period, so it is treated as a liability rather than income for the year ended 31 May 20X5.
Verify: −$4,000 (opening receivable reversed) + $25,000 + $19,000 − $5,000 (received in advance) = $35,000 ✓

Why Each Step Matters
The opening debit on 1 Jun 20X4 is the entry students most often misread as an expense. It is not — it is a reversal of an adjustment made in the previous year. The income for the period ($35,000) is determined by the closing entry, not by adding up cash receipts. Of the $44,000 cash received, $5,000 relates to rental not yet earned (set aside as income received in advance) and $4,000 was already recognised as income last year (reversed out by the opening entry) — leaving $35,000 as this year's income.
Misreading the opening debit as an expense — A debit on an income account at the start of the financial year is a reversal of the previous year's income receivable, not an expense.
Treating total cash received as the income for the period — The correct income figure is the closing entry amount ($35,000), after all adjustments. Total cash received was $44,000.
Omitting the income received in advance from the Statement of Financial Position — After the year-end set-aside, the $5,000 balance must appear as a current liability in the SoFP.
