BLAW30002 Chap.2 Tax Administration and Disputes
Tax Administration and Disputes
Tax administration connects a taxpayer's return to assessment, checking, amendment, objection, review and collection. Under self-assessment, the ATO generally processes information supplied by the taxpayer and issues a Notice of Assessment. Later data matching, review or audit can expose an error, and either the taxpayer or the ATO may initiate amendment within the applicable period.
A taxpayer who disputes an assessment must use the objection process, state full grounds and discharge the onus of showing that the assessment is excessive and what the correct assessment should be. The chapter also separates liability disputes from payment and collection problems.

Tax Administration and Disputes FAQ
Does a Notice of Assessment mean the return was audited?
No. Under self-assessment the ATO generally processes the information supplied and issues the assessment. Later data matching, review or audit may test an item and result in an amended assessment.
What is the difference between review and audit?
A review responds to an identified compliance risk and may end or escalate. An audit is a more intensive examination and can use formal information-gathering powers. The procedure described in the facts matters to the next step.
What must a tax objection include?
It must be lodged in the approved form, in writing, and state full grounds. The taxpayer should provide evidence for each disputed item and calculate the assessment said to be correct, rather than merely demanding that the ATO reconsider.
Who bears the onus in an objection?
The taxpayer bears the onus of proving that the assessment is excessive and establishing the correct amount. Showing that the Commissioner's reasoning may contain a weakness is not enough without a supported alternative.
What happens after an objection decision?
Depending on the review rights and issue, the taxpayer may seek merits review in the Administrative Review Tribunal or appeal through the Federal Court process. The two forums do not perform the same function.
Is inability to pay a reason to object?
Not by itself. If the taxpayer accepts the assessment but cannot pay immediately, the problem concerns collection and a possible payment arrangement. An objection addresses whether the assessment is legally correct.
What evidence should accompany a disputed assessment?
Match the evidence to every disputed inclusion, deduction or characterisation. Bank records, agreements, invoices and contemporaneous explanations should trace the amount and support the legal category claimed. State the corrected figure as well as the criticism of the Commissioner's result, because the taxpayer bears the onus of establishing the excessive part and the proper alternative.
Keep a request about hardship or timing separate: that material supports collection relief, not the substantive objection calculation.
Exam move
Draw the administration lifecycle from return to assessment, amendment, objection, decision and review. Put taxpayer actions in one lane and ATO actions in another so you can see who initiates each step. Practise three diagnoses: an error the taxpayer discovers, an ATO amended assessment the taxpayer disputes, and an accepted liability the taxpayer cannot pay immediately.
For objection problems, force yourself to write the full grounds and the corrected figure. Learn the difference between data matching, review and audit through what each process does, not merely its label. When discussing penalties or interest, identify the conduct and period before using a percentage or rate.
Finish every administration answer with the next lawful move, the person who must take it, the evidence required and the forum that follows if the dispute continues.
