Tax audit response preparation checklist
An ATO audit can range from a simple review to a comprehensive investigation. Early preparation, structured document production, and clear privilege protocols reduce both the duration and risk exposure of the audit.
This is a 12-step checklist for preparing a response to an ATO tax audit or review. It covers audit notification, access powers under the TAA 1953, privilege claims, and dispute resolution options.
The checklist
Review the audit notification
Analyse the ATO audit notification letter to identify the tax type, audit period, risk issues flagged, and response deadline.
Identify the audit type
Determine whether the activity is a review, audit, or investigation, as each has different procedural consequences.
Assess ATO access powers
Understand the scope of the ATO access powers under s 353-10 of Schedule 1 to the TAA and any limitations.
Activate privilege protocols
Identify legal professional privilege material and implement protocols to prevent inadvertent disclosure.
Gather primary records
Collect tax returns, financial statements, contracts, and supporting documentation for the audit period.
Review prior rulings and advice
Identify any private rulings, ATO advice, or settlement deeds relevant to the issues under audit.
Prepare position papers
Draft internal position papers on each issue, identifying the legislative basis, case law, and factual support for the taxpayer's position.
Assess amendment period exposure
Determine which assessment years are within the standard two-year or four-year amendment period, or whether fraud or evasion extends the period.
Calculate penalty exposure
Assess potential shortfall penalties (25%, 50%, or 75%) based on the level of culpability and whether reasonably arguable position defences apply.
Consider voluntary disclosure
Evaluate whether a voluntary disclosure before audit completion would reduce penalties under s 284-225.
Engage with the ATO audit team
Respond to the ATO within the stated deadline and establish a cooperative engagement protocol.
Plan dispute resolution pathway
If disagreement persists, identify the dispute resolution pathway: objection, ADR, AAT review, or Federal Court appeal.
When this checklist applies
Use when a client receives an ATO audit notification, review letter, or access request.
Common pitfalls
- Producing privileged documents without a proper review process
- Missing response deadlines and losing cooperative engagement benefits
- Failing to identify amendment period limitations early
- Underestimating penalty exposure on positions without a reasonably arguable basis
- Not considering voluntary disclosure before the audit concludes
