What this dot point is asking

A business prepares financial statements to report its performance and position to the owner and other users. The two core reports for a sole trader are the income statement and the balance sheet. A cash flow statement is also commonly prepared, but the income statement and balance sheet are the focus here.

The income statement (statement of financial performance)

The income statement measures profit for a period (for example, a year). It applies the matching principle: revenue earned in the period is matched against the expenses incurred in earning it.

Net Profit=RevenueExpensesNet\ Profit = Revenue - Expenses

For a trading business that buys and sells goods, an extra step calculates gross profit first:

Gross Profit=SalesCost of Goods SoldGross\ Profit = Sales - Cost\ of\ Goods\ Sold

Net Profit=Gross ProfitOperating ExpensesNet\ Profit = Gross\ Profit - Operating\ Expenses

Cost of goods sold itself is found as:

COGS=Opening Inventory+PurchasesClosing InventoryCOGS = Opening\ Inventory + Purchases - Closing\ Inventory

The balance sheet (statement of financial position)

The balance sheet lists what the business owns and owes at one date. It is a direct presentation of the accounting equation, Assets=Liabilities+Owners EquityAssets = Liabilities + Owner's\ Equity. Items are classified to make the report more useful:

  • Current assets: expected to be used or converted to cash within twelve months (cash, debtors, inventory).
  • Non-current assets: held longer than twelve months (equipment, vehicles, premises).
  • Current liabilities: due within twelve months (creditors, bank overdraft).
  • Non-current liabilities: due after twelve months (long-term loan).
  • Owner's equity: opening capital plus net profit, less drawings.

How the statements connect

The two reports are linked through owner's equity. Net profit calculated in the income statement is added to the owner's capital, and drawings are subtracted, to give the closing equity shown on the balance sheet:

Closing Capital=Opening Capital+Net ProfitDrawingsClosing\ Capital = Opening\ Capital + Net\ Profit - Drawings

Worked example

Classifying the income statement

A well-presented income statement groups items so the reader can see the layers of profit. Net sales (sales less sales returns) come first, then cost of goods sold gives gross profit. Operating expenses are usually grouped, for example into selling and distribution, administrative, and finance expenses, so a reader can see where profit is consumed. Finance costs such as interest are typically shown last because they relate to how the business is financed rather than to trading. This classified format makes trends easier to spot from year to year and feeds directly into the profitability ratios studied later.

Classifying the balance sheet

The balance sheet is classified into current and non-current items so users can judge liquidity. A standard order lists current assets (cash, debtors net of any allowance, inventory, prepaid expenses), then non-current assets (equipment and vehicles shown at cost less accumulated depreciation to give carrying amount). Liabilities split into current (creditors, GST owing, accrued expenses, bank overdraft) and non-current (long-term loans). Owner's equity shows opening capital, plus net profit, less drawings, to give closing capital. Presenting net debtors and carrying amounts here links this topic to the bad debts and depreciation adjustments.

How the statements reconcile

The two statements are not independent. The net profit figure calculated in the income statement is the same number that increases owner's equity in the balance sheet, and the closing cash on the balance sheet is the figure a cash flow statement reconciles to. Because everything ties back to Assets=Liabilities+Owner’s Equity\text{Assets} = \text{Liabilities} + \text{Owner's Equity}, a balance sheet that balances is strong evidence the recording, the adjustments and the profit calculation are all internally consistent. This is why examiners often ask you to prepare the income statement first, carry the profit into equity, and then prove the balance sheet balances.

Why this matters

Owners use the income statement to judge whether the business is profitable and the balance sheet to judge whether it is solvent and well financed. Being able to prepare both, and explain how profit feeds into equity, is central to financial accounting assessment.

Build net sales, then cost of goods sold, then gross profit, then net profit, then closing capital.

Net sales =2400006000=$234000= 240\,000 - 6\,000 = \$234\,000.
Cost of goods sold =30000+14000034000=$136000= 30\,000 + 140\,000 - 34\,000 = \$136\,000.
Gross profit =234000136000=$98000= 234\,000 - 136\,000 = \$98\,000.
Operating and finance expenses =38000+18000+7000+4000=$67000= 38\,000 + 18\,000 + 7\,000 + 4\,000 = \$67\,000.
Net profit =9800067000=$31000= 98\,000 - 67\,000 = \$31\,000.
Closing capital =90000+3100020000=$101000= 90\,000 + 31\,000 - 20\,000 = \$101\,000.

Markers reward deducting sales returns to get net sales, the correct COGS formula using opening and closing inventory, gross profit before expenses, net profit after all expenses including depreciation and interest, and the closing capital that adds profit and subtracts drawings.

TCE 20234 marksA sole trader's balance sheet does not balance: total assets are 182000whiletotalliabilitiesplusownersequityare182\,000 while total liabilities plus owner's equity are 176\,000. Explain two possible causes and describe the systematic process you would use to find the error.
Show worked answer →

A full 4 mark answer gives plausible causes and a logical search method.

The 60006\,000 difference could be caused by, for example: omitting an asset or liability; entering an amount on the wrong side; posting net profit or drawings incorrectly into equity; or a simple addition error in one of the columns. Any two reasonable causes earn the marks.

Process: first re-add each column to rule out an arithmetic slip; then check the equity section recalculates correctly (opening capital plus net profit less drawings); then trace each balance back to the adjusted trial balance to confirm every item is included once and on the correct side. Because the balance sheet must satisfy Assets=Liabilities+Owner’s Equity\text{Assets} = \text{Liabilities} + \text{Owner's Equity}, the imbalance proves an error exists and must be found before finalising. Markers reward two valid causes and a structured, equation-based checking process.
