ExploreAbout this exam
Core 4: Tax (NZ) is a module within the Chartered Accountants Australia and New Zealand (CA ANZ) CA Program, the practical pathway candidates complete after an accredited degree or conversion course on the way to CA membership and a Certificate of Public Practice. It suits graduate accountants and finance professionals working in or alongside New Zealand tax, whether in public practice, corporate tax, government or not-for-profit. The module builds technical knowledge of the New Zealand tax framework and the judgement to apply it: the Inland Revenue Acts, the compliance and dispute processes, income recognition and deductibility, the treatment of individuals, businesses and entities, GST, depreciation and property, cross-border issues, and avoidance and ethics. Assessment blends multiple choice, short answer and case-based scenario questions, so memorising rates is less useful than reasoning from principles to facts. Prepare by working through the official module materials and NZ tax legislation on a scheduled basis, then practising with scenario questions under time pressure. Keep current with Inland Revenue guidance and changes announced in the annual Budget and tax bills, because technical detail shifts. Confirm the current structure, assessment format, fees and key dates with CA ANZ, which publishes the authoritative details for each intake. The module rewards candidates who can explain why a treatment applies, not just state it.
What you'll study
About CA ANZ Core 4: Tax (NZ) preparation
What is the format of the Core 4: Tax (NZ) assessment?
Expect a mix of multiple choice, short answer and case-based scenario questions that test application of New Zealand tax rules to realistic facts. CA ANZ publishes the current assessment structure, weighting and any examination conditions for each intake, so check its site rather than relying on past candidates' descriptions.
How difficult is the module?
Most candidates find it demanding because it spans the whole tax system and rewards precision. Difficulty comes less from calculations than from applying rules to messy facts and explaining the reasoning. Candidates with day-to-day NZ tax exposure have an edge, but consistent study closes the gap.
Can I retake the assessment if I fail?
CA ANZ sets the rules on reassessment, additional attempts and any associated fees or waiting periods, and these can change. Confirm the current position in the official CA Program policies and candidate information on the CA ANZ website before you plan around a retake.
How long should I allow to prepare?
Plan across the whole module period rather than cramming. A common approach is weekly reading of module content and legislation, then a block of scenario practice in the final weeks. Working candidates often need more time in the entity, GST and property areas, where rules are detailed and interlock.
What study order works best?
Start with tax administration and income fundamentals, since deductions, timing and assessable income underpin everything later. Move to individuals and business income, then entities, GST, depreciation and property, and finally international issues and avoidance and ethics, which draw on all the earlier material.
Why do candidates fail?
Common causes are shallow coverage of entity and GST rules, memorising rates instead of principles, misreading scenario facts, and running out of time on longer answers. Weakness in ethics and avoidance reasoning also costs marks because those questions test judgement, not recall.
Do I need to memorise tax rates and thresholds?
You should know the structure of rates and thresholds and where to find current figures, but the assessment emphasises applying principles. Rates change through annual Budgets and tax bills, so confirm current numbers from Inland Revenue and the module materials rather than old study notes.
How much time does the assessment take?
CA ANZ publishes the current duration and conditions for the assessment, and these are not fixed across intakes. Check the official candidate information for your intake and practise full-length scenarios under timed conditions so your pace matches the real format.
Is the module open to people outside New Zealand?
The module is part of the CA ANZ CA Program, which serves candidates in both Australia and New Zealand. Entry requirements, enrolment eligibility and any recognition of prior study are set by CA ANZ, so confirm your circumstances with it directly before enrolling.
