79017 Chap.3 Business Income and Trading Stock
Business Income and Trading Stock
This chapter distinguishes carrying on a business from a hobby, investment or preparatory activity, then classifies receipts produced by that activity. Business status is determined from the whole pattern: intention, repetition, scale, commercial method, organisation, records and practices typical of the field. Normal proceeds are separated from extraordinary gains and isolated transactions.
Trading stock is then identified from purpose and ordinary business activity, valued under the permitted bases, and reconciled through the opening and closing stock adjustment.
The same taxpayer can conduct several activities with different tax characters, so define each activity before applying the indicators.
The same physical asset can also be stock for one taxpayer and an investment for another because purpose and ordinary operations differ. A sound answer therefore connects the receipt or asset to a precisely described business, preserves any extraordinary-transaction analysis, and shows the valuation basis and direction of the stock adjustment.

Closing-stock adjustment from supported values
- +1Compare the permitted supported bases. Replacement value of $28,500 is lower than cost and market selling value.
- +1Calculate closing less opening: $28,500 - $22,000 = $6,500.
- +1Because closing stock exceeds opening stock, the $6,500 difference is assessable rather than deductible.

Business Income and Trading Stock FAQ
Does a profit motive prove a business?
No. It is relevant but not conclusive. Apply the full pattern of repetition, scale, commercial method, organisation, records and conduct typical of the field. A small activity can be a business, while a profitable isolated event can remain outside a continuing business.
Can shares be trading stock?
They can be where the taxpayer carries on a share-trading business and holds the parcel for ordinary-course sale. A separate long-term investment parcel may have a different character. Purpose, conduct and records should be analysed for each portfolio rather than assumed from the asset type.
What if closing stock is lower than opening stock?
The decrease is generally a deductible stock adjustment under the chapter method. Show both values and the subtraction so the direction is visible. Then verify that the closing valuation basis is permitted and supported for the items actually on hand.
Exam move
For business questions, define the activity narrowly and build a two-column indicator table with facts for and against business status. Then analyse each disputed receipt separately: normal proceeds, extraordinary gain, isolated transaction or statutory route. For stock, identify purpose at acquisition and year end, choose a supported valuation basis, calculate closing less opening and state the direction.
Reconcile all partner, inventory or income figures back to the aggregate supplied in the question. Practise pairs of near-identical activities where commercial organisation differs, then explain which facts change the result. For stock, repeat one calculation under each permitted supported valuation basis and compare timing consequences.
Finish with a physical-count check, an on-hand finding and a one-sentence sign test for the year-end adjustment. Use a three-column receipt ledger headed normal operation, extraordinary commercial gain and statutory fallback. Force yourself to place every amount provisionally, then write the fact that could move it to another column.
For inventory, distinguish classification evidence from valuation evidence so a low number never substitutes for proving the item is stock.
