The short version
- Australia Taxation is about working out how much tax a taxpayer owes, and why.
- One idea holds the whole subject together: assessable income, less deductions, gives taxable income.
- Principles of taxable income is the biggest module. The rest builds on it, so start there.
- The exam has multiple choice and extended response, so know the rules and be able to show a calculation.
- This guide covers the eighth edition, which reflects the law as at 1 January 2025. Check the edition and the law date for your own exam.
What you are up against
Australia Taxation is a rules subject. It rewards knowing how the pieces fit and being able to apply them to a set of facts. The content is wide, and it is easy to feel buried in special cases. The way out is to hold on to the core structure and hang everything else off it.
That core is a single line: assessable income, less deductions, equals taxable income. Almost everything in the subject is either working out what counts as assessable income, working out what you can deduct, or applying a specific set of rules once you have taxable income. Keep that spine in view and the special cases stop feeling random.
Tax law changes every year, so the edition and the law date matter more here than in any other subject. This guide covers the eighth edition, which reflects the law as at 1 January 2025. Always confirm the edition and the effective date of the law for your own sitting before you make your notes, and never rely on last year’s rates.
Australia Taxation at a glance
Where the marks sit
One module stands above the rest. Principles of taxable income is a quarter of the exam, and it is the foundation the other modules sit on. The remaining marks are spread fairly evenly across capital gains, individuals, other entities, and the indirect taxes.
Module weighting in the Australia Taxation subject (illustrative of the published emphasis). Confirm the weighting for your own sitting against the current subject outline.
Illustrative only. Every subject differs. This shows the shape of a typical weighting, not the marks for any specific exam.
The plan is clear. Get principles of taxable income solid first, because everything else assumes it. Then work steadily across the other five, which are close in weight, so none can be skipped and none needs to dominate.
How tax payable is built up
Before any single module makes sense, get the overall calculation clear. Tax is not one number you look up. It is built in steps, and knowing the order stops most mistakes.
Principles of taxable income: the anchor
This module is a quarter of the exam because it defines the two things every other module depends on: what is assessable income, and what is a deduction. Assessable income is broader than a salary. It includes ordinary income, like wages, business profit and rent, and statutory amounts the law specifically brings in, like certain capital gains. Deductions then split into two kinds: general deductions, the costs incurred in earning that income, and specific deductions the law separately allows or limits.
The general deduction is where most questions live, and it works as a short test. A cost is deductible if it was incurred in earning assessable income and it is not private, domestic or capital in nature, and not blocked by a specific rule. Run that test the same way every time.
Exam trap
The most common slip is claiming a deduction for something that is private or capital in nature. A work lunch, the drive from home to the office, the cost of a new asset: each fails the test in a different way. Before you deduct anything, run the three checks, and if any one fails, it is not a general deduction.
CGT, individuals, other entities, and the indirect taxes
Capital gains sit slightly apart, and they follow their own short sequence. A capital gain happens on a CGT event, usually selling an asset. The gain is the capital proceeds less the cost base, and where an asset has been held long enough, a discount can reduce the taxable gain. Most CGT questions are really about getting the cost base right, since that is where the adjustments and the detail live.
Taxation of individuals then applies the whole calculation to a person, including the tax offsets that reduce the tax and the levies that add to it. Taxation of other entities covers how companies, trusts, partnerships and super funds are taxed, and the key point is that they are not all taxed the same way. Finally, GST and FBT are the indirect taxes: GST on most supplies, and fringe benefits tax on non-cash benefits given to employees. Each is worth learning as its own small system.
Learn each entity by how it is taxed
A company, a trust and a partnership are treated very differently. A company pays tax itself. A partnership does not, its partners do. A trust usually passes its income to beneficiaries, who are taxed on it. Get that one distinction firm and a lot of the entity questions answer themselves.
The topics that decide your result
How to study this subject
Australia Taxation is a doing subject. You learn it by working out tax on real fact patterns, not by re-reading rules. Build a one-page version of the tax payable calculation and keep it in front of you until it is automatic. For each module, write the steps you would follow, then practise questions until the steps run without thinking. The exam has extended-response questions, so practise setting out a calculation clearly and showing your working, because method marks are given for the steps even when a final figure is off. For the multiple choice, drill the rules that decide whether something is assessable or deductible.

Traps that cost easy marks
The four that catch people
Claiming a private or capital cost as a deduction. Getting the CGT cost base wrong, which throws the whole gain out. Treating every entity as if it were taxed the same way. And using an out-of-date rate or threshold from old notes. Each is avoidable if you keep the calculation and the tests in front of you and use current figures.
Assessable income, less deductions, equals taxable income. Almost everything in this subject hangs off that one line.
Questions people ask about Australia Taxation
- Is Australia Taxation a hard subject?
- It is wide rather than deep, and that is what makes it feel hard. There is a lot of detail. It becomes manageable once you hold on to the core calculation and hang each module off it rather than trying to memorise every special case.
- Which topics carry the most marks?
- Principles of taxable income is the biggest module at about a quarter of the exam, and it underpins the rest. The other five modules are close in weight, so none can be skipped.
- Do I need to memorise tax rates?
- You need to know how the calculation works and how to apply the rules to a set of facts. Rates and thresholds change each year, so learn the method rather than trusting numbers from old notes, and use the current figures for your sitting.
- How current does the law need to be?
- Very. Tax law changes yearly, so the edition and the effective date matter. This guide covers the eighth edition, which reflects the law as at 1 January 2025. Confirm the edition and the law date when you enrol.
- What edition is this guide written for, and how do I check mine?
- This guide is written for the eighth edition. Because the law is updated regularly, check the current edition and its law date when you enrol rather than trusting older notes.
