Tax administration is the machinery that makes substantive tax law work. Students need to understand how a return becomes an assessment, how the Commissioner changes it, what happens when tax is unpaid, and how a taxpayer challenges an ATO decision.
12.1 Tax administration is substantive law in practice
A tax lawyer does more than calculate taxable income. The system must decide who lodges, how assessments are made, when the Commissioner can amend them, how tax is collected, what happens when a taxpayer disagrees, when penalties arise and what protection is available from ATO advice. These rules are not an administrative afterthought; they determine whether a taxpayer can practically enforce the correct legal position.
The Commissioner's general administration functions arise under provisions including s 8 ITAA36, s 1-7 ITAA97 and s 3A of the Taxation Administration Act 1953 (Cth) (TAA53). Australia operates substantially on self-assessment: taxpayers are responsible for lodging correct information, while the ATO uses review, audit, information-gathering and enforcement powers.
12.2 Returns and lodgments
Section 161 ITAA36 requires a person to lodge a return where required by the Commissioner's legislative instrument for the relevant year. Section 161A requires the return to be in the approved form. Failure to lodge information required under a taxation law can attract both administrative and offence consequences, including s 8C TAA53 in appropriate circumstances.
Businesses can also have BAS/IAS obligations for GST, PAYG withholding, PAYG instalments, FBT instalments and other indirect taxes. The procedural form depends on the taxpayer's registrations and liabilities. Costs of managing tax affairs can be deductible under s 25-5 ITAA97.
12.3 Assessments — ss 166, 166A and 167 ITAA36
Under s 166 ITAA36, the Commissioner makes an assessment of taxable income, tax payable and relevant offset refunds using the return and other available information. Section 6(1) defines “assessment”. R v DCT; Ex parte Hooper establishes that an assessment is the Commissioner's formal ascertainment of liability, not merely the piece of paper communicating it.
Section 166A deals with full self-assessment taxpayers such as companies and complying superannuation funds: the law can deem an assessment to have been made on lodgment in accordance with the return. Section 167 allows a default assessment where a return has not been lodged, the Commissioner is dissatisfied with it, or has reason to believe taxable income was derived.
Default assessments are important because the taxpayer can carry a significant evidentiary burden when challenging them. The relevant rules include TAA53 ss 14ZZK and 14ZZO concerning the burden of proving an assessment excessive or otherwise incorrect and establishing the correct amount.
12.4 Notices and conclusiveness
Section 174 ITAA36 concerns service of a notice of assessment. Section 175 provides that non-compliance with a provision of the Act does not automatically invalidate an assessment. TAA53 Sch 1 s 350-10 contains evidentiary rules giving assessment documents significant conclusiveness, subject to the Pt IVC review/appeal process.
The practical lesson is that taxpayers usually challenge the substantive amount through the statutory objection and review system rather than trying to invalidate an assessment collaterally.
12.5 Amended assessments and limitation periods
The Commissioner can amend assessments within statutory amendment periods under s 170 ITAA36, with different periods and exceptions depending on taxpayer type, complexity, fraud/evasion and other circumstances. Students must use the period specified in the problem rather than assume every taxpayer has two or four years.
Where Part IVA is involved, the relevant rules also include special amendment consequences including s 177G. Always identify the assessment date because amendment and objection periods are calculated from statutory starting points.
12.6 Collection, due dates and interest
Once assessed, tax becomes a debt due to the Commonwealth under the tax-administration framework. Failure to pay on time can attract the general interest charge (GIC) and collection action. Taxpayers may seek payment arrangements, remission of interest in appropriate cases and review of some decisions. In a problem, distinguish liability for the underlying tax from administrative interest/penalty consequences.
12.7 Administrative penalties — TAA53 Sch 1 Pt 4-25
The uniform administrative penalty regime in TAA53 Sch 1 Pt 4-25 applies across taxation laws, subject to statutory detail. The relevant rules identify penalties for failures to lodge, false or misleading statements, positions that are not reasonably arguable, scheme shortfalls and failures to meet other tax obligations.
For statement penalties involving shortfall amounts, culpability matters. Intentional disregard attracts a higher base penalty than recklessness, which is higher than failure to take reasonable care. A separate penalty can arise where a taxpayer lacks a reasonably arguable position in the circumstances specified by the legislation. Increases can apply for hindrance or repeated conduct, and reductions can apply for voluntary disclosure.
Note that the penalty-unit amount applicable to relevant dates under Crimes Act 1914 (Cth) s 4AA. Because penalty units change, final publication should always verify the amount for the date of the conduct.
TAA53 Sch 1 s 298-10 requires written notice of an administrative penalty and reasons. Remission, assessment and review provisions must then be considered. Administrative penalties can coexist conceptually with offence provisions, although legislation coordinates the consequences where criminal prosecution is commenced.
12.8 Objections — Pt IVC TAA53
Part IVC creates the main tax dispute pathway. A dissatisfied taxpayer generally lodges a taxation objection in the approved form, within the applicable time limit and stating the grounds relied upon. Section 14ZW contains time-limit rules. For many individual/small-business assessments the relevant rules identify a two-year period, while more complex matters can involve four years; amended assessments have special timing rules.
The Commissioner must make an objection decision under s 14ZY. Section 14ZYA provides a mechanism under which a taxpayer can require a decision and, after the statutory period, obtain a deemed disallowance if no decision is made. This prevents an objection from remaining unresolved indefinitely.
12.9 Review and appeal — ART and Federal Court
After an objection decision, s 14ZZ TAA53 permits the taxpayer to choose the appropriate review/appeal route in accordance with the statutory framework. An application for merits review in the Administrative Review Tribunal must comply with the statutory time and procedural requirements, including s 14ZZC. A Federal Court appeal must also be commenced within the relevant period under provisions including s 14ZZN.
The distinction is important. The ART can undertake merits review within its jurisdiction; the Federal Court exercises judicial power and focuses on legal rights and questions within the appeal structure. Further appeals from ART decisions can be available on questions of law under the Administrative Review Tribunal Act 2024 (Cth).
Sections 14ZZK and 14ZZO are crucial: the taxpayer generally bears the burden of proving the assessment excessive or otherwise incorrect and of establishing what the correct assessment should be. A student should not write merely “the taxpayer can appeal”. Explain what must be proved.
12.10 Public rulings, private rulings and oral rulings
ATO rulings are central to practical tax advice. Div 357 TAA53 Sch 1 contains the general framework and taxpayer protection where a ruling applies and the taxpayer relies on it. If the Commissioner's published position is more favourable than the law ultimately proves to be, a binding ruling can protect the taxpayer from specified adverse consequences.
Public rulings under Div 358 state the Commissioner's view for entities generally or a class of entities. Private rulings under Div 359 apply to the applicant and the specified arrangement or question. Oral rulings for individuals about certain non-business matters are dealt with in Div 360.
A private ruling is not the same as informal ATO guidance, a website example or an edited private advice document. In professional practice, identify the legal status of the ATO material before telling a client they are “protected”.
12.11 Information-gathering powers
The Commissioner has broad statutory powers to obtain information and access premises for tax-administration purposes. TAA53 Sch 1 s 353-10 permits written notices requiring information, attendance to give evidence and production of documents. Section 353-15 provides access powers, subject to requirements including production of authority when requested. Section 353-25 addresses offshore information in relevant circumstances.
Industrial Equity Ltd v DCT confirms the breadth of information-gathering in the audit context. ANZ Ltd v Konza is important for the requirement that a notice be sufficiently certain to enable the recipient to identify what is required. The practical balance is broad investigatory power constrained by statutory requirements, privilege and public-law principles.
12.12 Record keeping and confidentiality
Section 262A ITAA36 requires businesses to keep records explaining relevant transactions for the statutory period, generally five years subject to detailed rules. Good records are not merely a compliance burden; they are essential evidence if a deduction, cost base, objection or audit is later disputed.
TAA53 Sch 1 Div 355 imposes strict confidentiality obligations on taxation officers, with statutory exceptions. Section 355-15 and related provisions can extend obligations to persons performing functions for the ATO. Tax administration therefore combines strong compulsory powers with statutory secrecy duties.
12.13 Authority and procedure map

| Penalties | Sch 1 Pt 4-25; s 298-10 | Culpability, shortfalls, disclosure and notice. |
12.14 Practical problem method
Tax-administration problems are easiest when put on a timeline. Write the dates of return lodgment, original assessment, amended assessment, objection, objection decision and proposed review/appeal. Then attach the statutory time limit to each date. This prevents procedural issues from becoming a mass of section numbers.
Next identify the status of every document the taxpayer relied on: legislation, public ruling, private ruling, edited private advice, website guidance or informal correspondence. Ask whether it binds the Commissioner and what protection it provides.
12.15 HD administrative-law IRAC
I — Issue
What decision or liability is challenged? Is the problem about assessment, amendment, penalty, objection, review, ruling or information notice?
R — Rule
Use the exact TAA53/ITAA36 provision. State the time limit, burden, form or statutory power. Cite Hooper, Industrial Equity or Konza only where their propositions are relevant.
A — Application
Put the facts on a timeline. Calculate expiry dates. Identify what evidence the taxpayer must produce and whether ATO material is binding.
C — Conclusion
State the procedural step available, deadline, burden of proof and likely consequence. If a penalty applies, separately consider remission/review.
12.16 Plain-English summary
Tax administration is the “how” of tax law. A taxpayer can be legally right about deductions but still lose a dispute by missing an objection deadline or failing to keep evidence. Learn the sequence: lodge → assess → amend → object → review/appeal. Learn the status of ATO advice. And always know who bears the burden of proving the correct tax result.

Self-assessment: liability, assessment and payment are distinct concepts
Substantive tax law creates liability, but administration determines how the liability is reported, assessed, collected, amended and disputed. A tax return is information supplied by the taxpayer. An assessment is a statutory act determining taxable income/tax or other liability under the relevant framework. Payment due dates and interest operate separately. Keeping these concepts separate is essential in problem questions.
Why this doctrine matters
Taxation problems rarely announce the correct legal category. The same commercial fact can have different consequences depending on whether it is characterised as ordinary income, statutory income, capital, deductible expenditure, a tax loss, a CGT event or an administrative matter. This topic therefore has to be learned as a reasoning process: identify the legal category first, select the exact provision second, connect the relevant authority third, and calculate only after those legal steps are complete.
Exact legal framework
Chapter 12 identifies ITAA36 ss 161/161A for returns, ss 166/166A/167 for assessment mechanisms, ss 174/175 for notices/effect, and s 170 for amendment periods, together with TAA53 machinery.
When reading the legislation, do not stop at the section number. Read the subsection that creates the rule, any paragraph that limits it, the definitions that give words a special meaning, and any exception or method statement. In an IRAC answer, reproduce only the operative elements needed for the facts, but identify them precisely enough that the reader can see why the rule is satisfied or not satisfied.
Authority and reasoning
Administrative cases such as Ex parte Ho are used to explain assessment concepts; the statutory scheme remains primary.
A case should be used for a proposition, not as decoration. State the factual feature that made the authority relevant, the rule or reasoning the court used, and then compare that feature with the new problem. If the facts point both ways, say so. The strongest tax answers often explain why one authority is closer and why a competing analogy is weaker. ATO rulings and guidance should be identified by type and legal effect rather than presented as though they were Acts or judgments.
Issue spotting
Spot what document/decision the taxpayer actually received: return obligation, original assessment, amended assessment, default assessment, penalty notice, objection decision or ruling.
Convert the facts into a short issue list before writing prose. Put the section beside each issue and the leading authority beside the section. This produces a disciplined sequence: taxpayer → income year → transaction → legal character → exact provision → authority → application → calculation → conclusion. If the topic has a timing or jurisdictional dimension, add a date line before the calculation.
Application, numbers and workpapers
Create an administration timeline with event date, statutory provision, deadline, consequence and available response.
Show the arithmetic in a workpaper or table and explain what legal rule authorises each line. A figure without a provision is only accounting. A provision without the figure is incomplete tax advice when the question supplies numbers. Reconcile the legal analysis to the final taxable-income, net-capital-gain, deduction, loss, penalty or procedural result.
Counterargument and conclusion
Before concluding, identify the strongest alternative characterisation. For example, ask whether a receipt could be a personal gift rather than a reward, whether expenditure is capital rather than revenue, whether a transaction is a mere realisation rather than a profit-making scheme, or whether an ATO document is merely guidance rather than binding protection. Resolve that alternative by reference to the statutory elements and the authority whose facts are closest.
Finish with a concrete conclusion: identify the amount included or deducted where the facts permit; state the income year; identify any amount carried forward; and add any consequential penalty, objection, review, ruling or other remedy/procedure that genuinely arises. Avoid conclusions such as “it depends” unless you identify exactly which missing fact changes the result.
Amendment periods and objections require date arithmetic
Tax procedure often turns on dates. Amendment periods differ according to taxpayer and circumstances. Objection periods can depend on the type of decision and notice. A legally strong answer calculates the final date rather than saying “the taxpayer may object within the statutory period”.
Why this doctrine matters
Taxation problems rarely announce the correct legal category. The same commercial fact can have different consequences depending on whether it is characterised as ordinary income, statutory income, capital, deductible expenditure, a tax loss, a CGT event or an administrative matter. This topic therefore has to be learned as a reasoning process: identify the legal category first, select the exact provision second, connect the relevant authority third, and calculate only after those legal steps are complete.
Exact legal framework
Use ITAA36 s 170 for amendment periods and Part IVC TAA53, including s 14ZU and related provisions, for objections. The Jade/Skye examples model the date calculation.
When reading the legislation, do not stop at the section number. Read the subsection that creates the rule, any paragraph that limits it, the definitions that give words a special meaning, and any exception or method statement. In an IRAC answer, reproduce only the operative elements needed for the facts, but identify them precisely enough that the reader can see why the rule is satisfied or not satisfied.
Authority and reasoning
The governing authority here is statutory. The learning value lies in applying exact dates, extensions and the effect of amended assessments.

State the factual feature that made the authority relevant, the rule or reasoning the court used, and then compare that feature with the new problem. If the facts point both ways, say so. The strongest tax answers often explain why one authority is closer and why a competing analogy is weaker. ATO rulings and guidance should be identified by type and legal effect rather than presented as though they were Acts or judgments.

Avoid conclusions such as “it depends” unless you identify exactly which missing fact changes the result.
Penalties and interest are separate from primary tax
An amended assessment can create additional primary tax, but that does not automatically answer interest or penalty. General interest charge, shortfall interest charge and administrative penalties have different functions and statutory bases. Penalty percentages depend on culpability, scheme treatment and other factors, and can be increased/reduced or remitted according to the legislation.

Exact legal framework
TAA53 Sch 1 Pt 4-25 includes penalties for false/misleading statements, failure to take reasonable care, recklessness, intentional disregard, scheme benefits and other failures. Chapter 12 also identifies penalty units and remission/adjustment concepts.
When reading the legislation, do not stop at the section number. Read the subsection that creates the rule, any paragraph that limits it, the definitions that give words a special meaning, and any exception or method statement. In an IRAC answer, reproduce only the operative elements needed for the facts, but identify them precisely enough that the reader can see why the rule is satisfied or not satisfied.
Authority and reasoning
Cases are less central than statutory classification of conduct. ATO guidance can explain administrative practice but cannot replace the Schedule 1 tests.
A case should be used for a proposition, not as decoration. State the factual feature that made the authority relevant, the rule or reasoning the court used, and then compare that feature with the new problem. If the facts point both ways, say so. The strongest tax answers often explain why one authority is closer and why a competing analogy is weaker. ATO rulings and guidance should be identified by type and legal effect rather than presented as though they were Acts or judgments.
Issue spotting
Spot whether the issue is late lodgment, false statement, shortfall, no reasonably arguable position, scheme benefit or failure to comply. Identify culpability and disclosure timing.
Convert the facts into a short issue list before writing prose. Put the section beside each issue and the leading authority beside the section. This produces a disciplined sequence: taxpayer → income year → transaction → legal character → exact provision → authority → application → calculation → conclusion. If the topic has a timing or jurisdictional dimension, add a date line before the calculation.
Application, numbers and workpapers
Use an assessment ledger: primary tax shortfall; GIC/SIC period; base penalty rate/units; increase/reduction; remission; total disputed amount.
Show the arithmetic in a workpaper or table and explain what legal rule authorises each line. A figure without a provision is only accounting. A provision without the figure is incomplete tax advice when the question supplies numbers.

Avoid conclusions such as “it depends” unless you identify exactly which missing fact changes the result.
Objection, ART review and Federal Court appeal
A taxpayer dissatisfied with an assessment or other reviewable tax decision ordinarily follows Part IVC. The objection must state grounds fully and in detail. If dissatisfied with the objection decision, the taxpayer may seek ART review or appeal to the Federal Court according to the statutory pathway. The taxpayer bears the statutory burden concerning excessiveness/incorrectness and the correct assessment.
Why this doctrine matters
Taxation problems rarely announce the correct legal category. The same commercial fact can have different consequences depending on whether it is characterised as ordinary income, statutory income, capital, deductible expenditure, a tax loss, a CGT event or an administrative matter. This topic therefore has to be learned as a reasoning process: identify the legal category first, select the exact provision second, connect the relevant authority third, and calculate only after those legal steps are complete.
Exact legal framework
This chapter identifies ss 14ZZ, 14ZZC, 14ZZK, 14ZZO and 14ZZN TAA53. ART review can address facts and law; the Federal Court route identified in the materials is on a question of law. Administrative Review Tribunal Act 2024 (Cth) s 172 is identified for appeals from ART decisions on questions of law.
When reading the legislation, do not stop at the section number. Read the subsection that creates the rule, any paragraph that limits it, the definitions that give words a special meaning, and any exception or method statement. In an IRAC answer, reproduce only the operative elements needed for the facts, but identify them precisely enough that the reader can see why the rule is satisfied or not satisfied.
Authority and reasoning
The procedural rules themselves are the authority. Students should not treat judicial review, merits review and tax appeal as interchangeable labels.
A case should be used for a proposition, not as decoration. State the factual feature that made the authority relevant, the rule or reasoning the court used, and then compare that feature with the new problem. If the facts point both ways, say so. The strongest tax answers often explain why one authority is closer and why a competing analogy is weaker. ATO rulings and guidance should be identified by type and legal effect rather than presented as though they were Acts or judgments.
Issue spotting
Spot grounds omitted from the original objection, the 60-day periods identified in this chapter, the decision challenged and whether factual reconsideration is needed.
Convert the facts into a short issue list before writing prose. Put the section beside each issue and the leading authority beside the section. This produces a disciplined sequence: taxpayer → income year → transaction → legal character → exact provision → authority → application → calculation → conclusion. If the topic has a timing or jurisdictional dimension, add a date line before the calculation.
Application, numbers and workpapers
Write the remedy conclusion procedurally: lodge objection by X; if disallowed, choose ART/Federal Court on the stated basis; taxpayer bears burden; later appeal on question of law where available.
Show the arithmetic in a workpaper or table and explain what legal rule authorises each line. A figure without a provision is only accounting. A provision without the figure is incomplete tax advice when the question supplies numbers. Reconcile the legal analysis to the final taxable-income, net-capital-gain, deduction, loss, penalty or procedural result.
Counterargument and conclusion
Before concluding, identify the strongest alternative characterisation. For example, ask whether a receipt could be a personal gift rather than a reward, whether expenditure is capital rather than revenue, whether a transaction is a mere realisation rather than a profit-making scheme, or whether an ATO document is merely guidance rather than binding protection.

Avoid conclusions such as “it depends” unless you identify exactly which missing fact changes the result.
Rulings, PCGs and edited private advice have different legal effects
ATO materials differ in authority. Public rulings express the Commissioner’s view and can protect a taxpayer who relies on an applicable ruling under the statutory framework. Private rulings apply to the applicant and specified arrangement. Edited private advice published for other taxpayers is informative but not binding protection for another taxpayer. Practical Compliance Guidelines generally describe compliance/risk approaches rather than changing substantive law.
Why this doctrine matters
Taxation problems rarely announce the correct legal category. The same commercial fact can have different consequences depending on whether it is characterised as ordinary income, statutory income, capital, deductible expenditure, a tax loss, a CGT event or an administrative matter. This topic therefore has to be learned as a reasoning process: identify the legal category first, select the exact provision second, connect the relevant authority third, and calculate only after those legal steps are complete.
Exact legal framework
TAA53 Sch 1 Div 357 contains general ruling rules; Div 358 public rulings; Div 359 private rulings. This chapter contrasts TR 2011/6 with edited private advice in Week 13.
When reading the legislation, do not stop at the section number. Read the subsection that creates the rule, any paragraph that limits it, the definitions that give words a special meaning, and any exception or method statement. In an IRAC answer, reproduce only the operative elements needed for the facts, but identify them precisely enough that the reader can see why the rule is satisfied or not satisfied.
Authority and reasoning
The key reasoning is hierarchy: Act/case law determines law; a binding ruling can constrain the Commissioner in the statutory circumstances; other guidance may be persuasive/administrative only.
A case should be used for a proposition, not as decoration. State the factual feature that made the authority relevant, the rule or reasoning the court used, and then compare that feature with the new problem. If the facts point both ways, say so. The strongest tax answers often explain why one authority is closer and why a competing analogy is weaker. ATO rulings and guidance should be identified by type and legal effect rather than presented as though they were Acts or judgments.
Issue spotting
Whenever an exam gives an ATO document, identify its type before relying on it. Ask who it applies to, whether it is binding, and what protection follows.
Convert the facts into a short issue list before writing prose. Put the section beside each issue and the leading authority beside the section. This produces a disciplined sequence: taxpayer → income year → transaction → legal character → exact provision → authority → application → calculation → conclusion. If the topic has a timing or jurisdictional dimension, add a date line before the calculation.
Application, numbers and workpapers
For FBC, TR 2011/6 can provide public-ruling protection if applicable and followed; edited private advice for someone else cannot. A private ruling under Div 359 is the route to arrangement-specific advice.
Show the arithmetic in a workpaper or table and explain what legal rule authorises each line. A figure without a provision is only accounting. A provision without the figure is incomplete tax advice when the question supplies numbers. Reconcile the legal analysis to the final taxable-income, net-capital-gain, deduction, loss, penalty or procedural result.
Counterargument and conclusion
Before concluding, identify the strongest alternative characterisation. For example, ask whether a receipt could be a personal gift rather than a reward, whether expenditure is capital rather than revenue, whether a transaction is a mere realisation rather than a profit-making scheme, or whether an ATO document is merely guidance rather than binding protection. Resolve that alternative by reference to the statutory elements and the authority whose facts are closest.
Finish with a concrete conclusion: identify the amount included or deducted where the facts permit; state the income year; identify any amount carried forward; and add any consequential penalty, objection, review, ruling or other remedy/procedure that genuinely arises. Avoid conclusions such as “it depends” unless you identify exactly which missing fact changes the result.

Every legislative reference detected in the relevant chapter materials — teaching map
This layer is intentionally exhaustive. It preserves the source wording that triggered the reference, then explains how a student should use that reference. It does not replace reading the current official provision.
Exact statutory reference
Read the provision at the section, subsection and paragraph level. Identify the operative verb, taxpayer/entity, factual conditions, exceptions, timing rule and consequence. Then connect the relevant case/ruling to the particular word or legal test it explains. Do not rely on the section number alone.
Application discipline: identify the precise element or method step this reference controls, apply the facts to that element, then carry the legal conclusion into the numerical workpaper. Where the source line refers to proposed/future law, keep it expressly separate from enacted law applying to the income year.
Reference context: Every person must, if required by the Commissioner by legislative instrument, give to the Commissioner a return for a year of income within the period specified in the instrument: s 161 ITAA36.
Return lodgment
Identify whether and how the taxpayer is required to lodge under the return/approved form framework for the relevant year.
Application discipline: identify the precise element or method step this reference controls, apply the facts to that element, then carry the legal conclusion into the numerical workpaper. Where the source line refers to proposed/future law, keep it expressly separate from enacted law applying to the income year.
Reference context: The Taxation Laws (Requirement to Lodge a Return for the 2026 Year) Instrument 2026 was made by the Commissioner and registered on 22 May 2026. The instrument sets out who must lodge a return for the 2025-26 income year. For example, it includes all employees who had PAYG withholding applied to their salary or wages for the 2025-26 year: s 6.

Reference context: The rules relating to the recovery of income tax (¶25-510) also generally apply in relation to administrative penalties. Assessments of penalties and, with certain exceptions, decisions relating to the remission of penalties are reviewable in accordance with TAA Pt IVC (TAA Sch 1 s 298-30; Huang 2025 ATC ¶20-978; [2025] FCA 1314; ¶28-000, ¶29-410). The Commissioner’s power to assess penalties under s 298-30(1) is not “spent” once exercised; the Commissioner can still amend the penalty after a notice of penalty assessment has been issued (Ziegler; Wellton Holdings Pty Ltd 2025 ATC ¶20-983; [2025] FCAFC 168).

Case, ruling and authority map
Authority context: See also the definition of an “assessment” in
s 6(1) ITAA36. An assessment is the Commissioner’s formal ascertainment of liability, not merely the paper notice:
R v DCT; Ex parte Hooper (1926) 37 CLR 368.
This authority is relevant to the chapter topic. Use it only for the legal proposition it actually supports: state the material facts/issue, extract the rule or reasoning, compare the problem facts, and explain whether the authority supports or distinguishes the taxpayer’s position. Verify the current status and citation when preparing assessed work.
How to deploy it: state the proposition in one sentence, identify the material factual analogy or distinction, then connect that reasoning to the statutory provision. Do not cite the authority for a broader proposition than the authority or judgment supports.
This is ATO interpretative/compliance material identified here. Use it to explain the Commissioner’s view or compliance approach, but distinguish it from the binding force of the Act and judicial precedent. Identify whether it is a public ruling, determination or guideline because the legal protection and function differ.

Problem-solving method — from facts to final advice
- Identify the taxpayer/entity and capacity in which the taxpayer acts.
- Identify the income year and any critical dates, residence periods, asset acquisition/disposal dates or administrative deadlines.
- Split the facts into separate receipts, outgoings, assets, liabilities, losses, tax credits and ATO decisions.
- For each item, identify the exact Act, Part/Division/Subdivision, section, subsection and paragraph that creates the rule.
- Break the provision into elements or method steps. Put each element beside the fact that satisfies or contradicts it.
- Add the case, ruling or ATO authority only for the proposition it explains. State why that authority is analogous or distinguishable.
- Resolve competing characterisations before calculating: ordinary/statutory/exempt/NANE/capital; deductible/capital/private; business/hobby; revenue asset/capital asset; CGT/Div 40/Div 43.
- Show the tax calculation in statutory order. Keep tax losses, capital losses, offsets, credits, GST and accounting entries in their proper regimes.
- Address the strongest counterargument and explain why the preferred characterisation is stronger.
- Conclude with the tax consequence and amount, income year, carried-forward balance and any penalty, objection, review, ruling or other procedural consequence genuinely raised by the facts.
IRAC / tax advice writing model
ISSUE. Write a narrow issue for each receipt, outgoing or transaction. Example: “Whether the $X received for Y is ordinary income under s 6-5 in the 2025–26 income year” is stronger than “Is the money taxable?”.
RULE / LAW. State the exact statutory rule and its elements. Where the rule is judicially developed, state the authority and proposition. Where an ATO ruling is relevant, identify its type and legal effect.
APPLICATION / REASONING. Apply facts to each element. Compare with authority. Explain both the favourable and adverse facts. If characterisation is uncertain, analyse the competing category and resolve it.
CALCULATION. Translate the legal conclusion into numbers using a separate schedule. Cite the statutory method step beside the arithmetic. Reconcile accounting amounts to tax amounts where relevant.
CONCLUSION. State the amount included/deducted/gained/lost or the procedural result. Then state any carried-forward balance, penalty/remedy or next administrative step.
