ATO & Tax Lawyers › ATO Audit Defence
ATO Audit Defence Lawyers — Protect Your Rights. Control the Process.
An ATO audit is not a routine administrative process — it is an adversarial investigation with significant consequences if managed poorly. A tax lawyer manages every aspect of the audit: responding to information requests, asserting legal professional privilege, preventing scope creep, negotiating with the ATO, and challenging any amended assessment that results. Early legal engagement produces materially better outcomes.
⚠ The ATO can issue an amended assessment up to 2 years after the original assessment for individuals and small business entities, and 4 years for others — with no time limit where fraud or evasion is alleged. Early legal engagement controls the audit and limits exposure. Get advice now.
ATO Audit Matters We Handle
From the first information request to the amended assessment — and beyond.
ATO Review & Audit Management
The ATO distinguishes between a "review" (less formal, shorter timeframe) and an "audit" (formal, broader powers). A lawyer manages the process from the initial notification letter, controls the scope of information provided, and negotiates with the ATO case officer to achieve the best outcome without unnecessary disclosures.
Responding to s353-10 Information Requests
Under s353-10 of Schedule 1 to the Tax Administration Act 1953, the ATO can require a person to attend and give evidence, produce documents, and answer questions. A lawyer reviews each information request, identifies what must be produced and what is protected by privilege, and prepares a compliant response that does not concede more than required.
Legal Professional Privilege Claims
Legal professional privilege protects confidential communications between a lawyer and their client from compulsory disclosure. The ATO cannot compel production of privileged documents. A lawyer identifies documents subject to privilege, prepares a privilege log, and manages any dispute with the ATO about the scope of privilege.
Position Paper Responses
Before issuing an amended assessment, the ATO typically provides a "position paper" or "audit findings" letter setting out its proposed adjustments. A lawyer prepares a detailed written response to the position paper — presenting the taxpayer's legal and factual arguments, identifying weaknesses in the ATO's position, and reducing the amended assessment before it is issued.
Voluntary Disclosure Management
Where the audit reveals an exposure, voluntary disclosure before the audit commences can reduce shortfall penalties from up to 75% to as little as 5% of the shortfall amount. A lawyer advises on whether voluntary disclosure is appropriate, prepares the disclosure in the most favourable terms, and negotiates penalty and interest remission.
Amended Assessment & Objection
Where the ATO issues an amended assessment following the audit, a lawyer lodges a formal objection under Part IVC of the Tax Administration Act 1953, pursues the matter to the Administrative Appeals Tribunal or Federal Court if disallowed, and seeks a stay of collection if the disputed amount is unmanageable pending the appeal.
The Legal Framework
ATO audit powers — what the law says.
s353-10 TAA 1953 — ATO access and information powers
The ATO's information-gathering powers under s353-10 of Schedule 1 to the TAA 1953 are broad — the Commissioner can require any person (not just the taxpayer) to provide documents, attend for interview, and answer questions. Failure to comply is a criminal offence. These powers are not unlimited — they must be exercised for a legitimate purpose, and legal professional privilege applies to protect privileged communications. A lawyer who understands the scope and limits of these powers can manage the information-gathering process strategically.
Amendment periods — 2 years, 4 years, unlimited
Under s170 of the ITAA 1936 and equivalent provisions, the ATO can amend an income tax assessment within 2 years of the original assessment for individuals and small business entities (SBEs), and within 4 years for all other taxpayers. Where the Commissioner is of the opinion that the taxpayer has engaged in fraud or evasion, the amendment period is unlimited — the ATO can go back as many years as it considers appropriate. This makes any allegation of fraud or evasion extremely serious — a lawyer must be engaged immediately to prevent the audit from expanding beyond the standard amendment period.
Shortfall penalties — Subdivision 284-B ITAA 1997
Shortfall penalties under Subdivision 284-B of the ITAA 1997 are imposed where a tax assessment is amended because the taxpayer's position was incorrect. The base penalty is 25% for failure to take reasonable care, 50% for recklessness, and 75% for intentional disregard of the law or fraud. These penalties can be reduced by a factor of 20% where the taxpayer makes voluntary disclosure before the audit commences, or by 10% where disclosure is made after the audit commences but before the position paper is issued. A lawyer maximises penalty reduction by managing the timing and scope of any voluntary disclosure.
General interest charge (GIC) — s8AAB TAA 1953
The general interest charge (GIC) under s8AAB of the TAA 1953 accrues daily on all unpaid ATO debts — including disputed amounts — at a rate set by the ATO each quarter (currently around 11% per annum, compounding daily). GIC accrues from the date the tax was due, not from the date of the audit. This means that a successful objection or appeal must include a claim for remission of GIC — which the ATO has a discretion to grant in appropriate cases. A lawyer prepares a comprehensive penalty and GIC remission submission as part of the overall dispute resolution strategy.
ATO model litigant obligations — Attorney-General's guidelines
The ATO, as a Commonwealth agency, is subject to model litigant obligations under the Legal Services Directions 2017. These obligations require the ATO to act honestly and consistently, avoid unnecessary legal costs, not take technical points to defeat clearly meritorious claims, and consider alternative dispute resolution in appropriate cases. A tax lawyer who understands and invokes the model litigant obligations can use them to encourage the ATO to concede issues, consider settlement, and approach the dispute in a commercially reasonable way.
Independent Review — ATO's internal escalation
Before issuing an amended assessment, the ATO offers taxpayers the option to request an independent review of the audit case officer's proposed adjustments. This review is conducted by a separate ATO officer not involved in the audit. While not binding, an independent review can result in adjustments being withdrawn or reduced — and the review officer's reasoning provides valuable intelligence about the ATO's approach that informs the subsequent objection and appeal strategy. A lawyer prepares detailed independent review submissions and uses the outcome strategically in the objection process.
