What Information Do You Have to Give the ATO in an Audit (and What You Don’t)

You get an email from the ATO. “We’re conducting a review and need some information from you.”

Your first instinct might be to send everything. Show cooperation. Get it over with quickly.

But here’s what most business owners don’t realise: not every request needs an immediate “yes”. And cooperation doesn’t mean handing over documents you’re entitled to protect.

The difference between a well-managed audit and one that spirals into a costly dispute often comes down to how you handle the first information request. Understanding what you must provide, what you can protect, and how to respond strategically makes all the difference.

This isn’t about being obstructive. It’s about being disciplined.

When the ATO Asks: Understanding How Information Gathering Works

The ATO doesn’t have unlimited power to demand whatever it wants, whenever it wants it. But it has substantial formal powers when it needs them.

Most audits start informally. An email or phone call from an ATO officer: “We’re reviewing your tax affairs and would like some information.”

At this stage, there’s no legal notice. No formal demand. You’re under no statutory obligation to comply immediately or provide everything requested without question.

This is the phase where smart businesses get strategic.

The ATO prefers this cooperative approach. Most audits stay in this informal phase, and many conclude without escalation. But the informal tone doesn’t mean you should treat the request casually.

If the audit escalates or you don’t cooperate with informal requests, the ATO can shift to formal powers: issuing notices under legislation that create enforceable legal obligations. These notices can require you to give information, produce documents, or attend and give evidence.

Understanding which phase you’re in changes everything about how you should respond.

Informal ATO Requests: How Much You Should Give (and on What Terms)

An informal request might arrive by email: “Can you please provide copies of all documents relating to [topic] for the 2022 and 2023 financial years?”

It sounds simple. But that single sentence hides a dozen decisions.

What does “all documents” mean? Emails? Board papers? Draft advice? Working files your accountant created?

What does “relating to” mean? Directly about the issue? Tangentially connected? Mentioned in passing?

Most business owners instinctively start gathering files and hitting reply. But this is the moment to pause.

You’re entitled to ask questions. Clarify scope. Understand why the information is needed and how it will be used. Suggest a narrower, more targeted approach.

This isn’t being difficult. It’s being professional.

A well-managed response to an informal request looks like this:

You acknowledge the request promptly. You engage advisors to review what’s being asked and what you hold. You identify any material that might be privileged or sensitive. You write back asking for clarification on scope, timeframe, and format.

Then you provide what’s clearly within scope, document what’s been provided, and flag (without waiving) any material you believe is protected.

This approach shows cooperation. But it also maintains boundaries.

The risk of informal requests is that they feel low-stakes. A “quick chat” with an auditor. An email asking for “just a few documents”. Business owners respond without thinking through the implications.

Then six months later, those casually provided documents become the foundation of an amended assessment or a penalty case.

Can you articulate, right now, what your business would send if an informal ATO request landed tomorrow? If you can’t, that’s the gap that needs closing.

ATO Formal Notices: What You Are Legally Required to Provide

A formal notice is different.

It will usually arrive in writing, clearly stating that it’s issued under specific legislative powers. It will specify what you must do: give information, produce documents, or attend to give evidence. It will set a deadline.

And it will warn you of the consequences of non-compliance: prosecution, significant penalties.

When you receive a formal notice, your obligations change. You are now legally required to comply, subject to very limited exceptions.

The ATO’s formal powers are broad. A notice can require you to:

• Give the Commissioner information (in writing or otherwise) about your affairs or someone else’s affairs
• Attend before an ATO officer at a specified time and place to answer questions and give evidence
• Produce documents in your custody or control

These powers extend beyond your own tax affairs. The ATO can issue notices to third parties: your bank, your customers, your advisors, anyone who might hold relevant information.

The practical effect is this: once a formal notice is validly issued, non-compliance is not an option.

What does “validly issued” mean? The notice must be within the Commissioner’s power, it must specify what’s required with reasonable clarity, and the deadline must be reasonable in the circumstances.

If a notice is vague, unreasonable, or beyond the Commissioner’s power, you may have grounds to challenge it. But those circumstances are rare.

Far more common is a validly issued notice that requires compliance, full stop.

Can you extend the deadline? Sometimes. If the request is genuinely complex or voluminous, the ATO will often grant an extension. But you need to ask, with reasons, before the deadline expires.

Can you refuse to produce documents? Only if they’re subject to legal professional privilege or another recognised protection. And you need to raise that specifically, with proper justification.

Can you refuse to answer questions? Generally, no. The privilege against self-incrimination operates differently in tax law. Being required to provide information or documents that might incriminate you does not, in most circumstances, give you a right to refuse.

Failure to comply with a formal notice is a criminal offence. The penalties are not trivial: prosecution, fines, and the reputational damage that comes with it.

If you receive a formal notice and you’re uncertain about any aspect of it, get legal advice immediately. The deadline is not negotiable without agreement, and the consequences of getting it wrong are serious.

Information You Can Protect: Privilege and Concessions in Practice

Not everything the ATO asks for must be provided.

Three main categories of protection exist: legal professional privilege, the accountants’ concession, and the corporate board advice concession.

Understanding these protections and how to raise them without accidentally waiving them is critical.

Legal professional privilege protects confidential communications between you and your lawyer made for the dominant purpose of giving or receiving legal advice, or for use in current or anticipated litigation.

This is a fundamental right. The ATO recognises it, and courts enforce it rigorously.

But privilege is easy to waive. Forward your lawyer’s advice to a third party who’s not part of the privileged relationship? Waived. Include the advice in a broader commercial email chain? Likely waived. Let the ATO see the advice during an on-site visit without raising privilege? Waived.

Privilege must be raised clearly and early. If the ATO requests documents and some are privileged, you need to identify them specifically (often in a privilege log) and state the grounds for withholding them.

Do not send the documents and hope the ATO doesn’t use them. Do not redact parts and send the rest without advice. Do not try to summarise privileged advice in your response.

If you’re not sure whether something is privileged, get advice. The test is technical, and the consequences of getting it wrong are permanent.

The accountants’ concession is an administrative practice, not a legal right. The ATO will generally not require you or your accountant to produce documents that record:

• Advice given by the accountant to you
• Calculations, workings, or analysis prepared by the accountant in formulating that advice

The concession exists because the ATO recognises that requiring disclosure of these working papers would undermine the advisory relationship and make it harder for taxpayers to get competent advice.

But it’s a concession, not an absolute protection. The ATO can withdraw it if there’s evidence of fraud, evasion, or deliberate misrepresentation. And it doesn’t apply to the underlying source documents: invoices, contracts, financial records, board minutes. Those must still be produced.

If the ATO asks your accountant for working papers, you and your accountant should coordinate your response. The accountant shouldn’t simply refuse; they should explain the basis for the concession and confirm with you that you want it raised.

The corporate board advice concession protects confidential advice given to a company’s board by external advisors (lawyers, accountants, other professionals) on matters within the board’s governance responsibilities, including tax risk.

This concession recognises that directors have duties to consider and manage risk, and they need to be able to receive frank, confidential advice without that advice automatically becoming available to the ATO in an audit.

Like the accountants’ concession, this is an administrative practice. It doesn’t apply to all board papers, and it can be displaced in cases of serious misconduct.

But for legitimate board deliberations on tax risk, the concession provides meaningful protection.

To rely on it, the advice must be genuinely addressed to the board (or a board committee), it must be confidential, and it must relate to governance rather than operational tax advice.

If the ATO requests board papers in an audit, don’t assume you must hand everything over. Consider whether the board advice concession applies, and if so, raise it clearly in your response.

Privilege and concessions are powerful protections. But they only work if you know they exist, raise them properly, and don’t accidentally waive them through careless disclosure.

ATO Access Powers: What Happens When Officers Visit Your Premises

The ATO doesn’t always wait for you to send documents. Sometimes, they come to you.

The Commissioner has powers to authorise ATO officers to enter and remain on your business premises at any reasonable time. Once there, they have “full and free access” to books, documents, and other property for the purposes of the tax laws.

This can feel intrusive. Officers walking through your office, asking to see files, taking notes, speaking to staff.

But access powers are not a free-for-all. There are limits, and you’re entitled to manage the visit professionally.

First, the officers must identify themselves and show their authorisation. You’re entitled to see their credentials and understand the scope of the visit.

Second, the access is for “books, documents, and property”. That’s broad, but it’s not unlimited. Officers can look at business records, financial documents, and physical assets. They can ask questions. But they cannot search personal belongings, demand access to locked areas without reasonable grounds, or behave in a way that disrupts your business unnecessarily.

Third, you are required to provide “reasonable facilities and assistance” for the officers to exercise their powers. That means giving them a workspace, access to relevant files, and cooperation from staff who can locate documents.

It does not mean letting officers roam freely without supervision, allowing them to take documents away without recording what’s been copied, or permitting unstructured conversations with staff that might inadvertently disclose privileged information.

The smart way to handle an access visit is to prepare in advance. If you know the ATO is conducting an audit and there’s a possibility of a site visit, set protocols:

• Designate a senior person (with legal or tax advisor support) to coordinate the visit
• Instruct staff to refer all questions to that person rather than answering directly
• Set up a meeting room where officers can work, rather than having them move through operational areas
• Keep a log of what documents are inspected or copied
• If officers ask to see something that might be privileged, politely pause and check with your advisor before providing access

You cannot refuse access to business records that fall within the scope of the visit. But you can manage the process so it’s orderly, documented, and protective of your interests.

If ATO officers exceed their powers, behave unreasonably, or seek access to material you believe is privileged, raise the issue calmly and document it. If necessary, contact their manager or seek legal advice on next steps.

Access visits are a normal part of serious audits. They’re not a crisis. But they require discipline and preparation.

ATO Interviews and Questioning: Handling Demands for Evidence

A formal notice can require you to attend before an ATO officer to answer questions and give evidence.

This is not optional. If the notice is validly issued, you must attend at the specified time and place.

The interview might be at ATO offices, or it might be at your business premises. It might be a single session or multiple sessions. The ATO officer will usually take notes or record the interview.

You can have a lawyer or advisor with you. That’s your right, and you should exercise it. An experienced advisor will help you understand the questions, avoid inadvertent errors, and ensure the process stays within proper bounds.

But your advisor cannot answer for you. The notice requires you to give evidence. That means you must respond to questions personally.

Can you refuse to answer? Generally, no. The privilege against self-incrimination, which allows you to refuse to answer questions that might expose you to criminal prosecution, operates differently in tax matters.

The general rule is that the privilege does not protect you from being required to give information or produce documents under a formal notice, even if that information might later be used in a criminal prosecution.

There are very narrow exceptions, but they are not something you can rely on without specific legal advice in the circumstances.

So what do you do if you’re required to attend an interview and you’re worried about the implications?

First, prepare thoroughly. Work with your advisor to understand the issues the ATO is investigating, review the relevant facts and documents, and anticipate the questions you might be asked.

Second, answer truthfully and accurately. Do not guess, speculate, or try to “fill gaps” in your knowledge. If you don’t know the answer, say so. If you need to check records or refresh your memory, say so.

Third, answer the question that was asked, not the question you wish had been asked. Volunteering additional information, explaining context that wasn’t requested, or offering opinions on tangential issues is how interviews go wrong.

If a question is unclear, ask for clarification. If a question assumes facts you don’t agree with, correct the assumption. If a question seeks information you believe is privileged, raise that with your advisor before answering.

The ATO officer conducting the interview is not your adversary, but they are not your friend. Their job is to gather information. Your job is to provide accurate answers within the scope of your legal obligations, and nothing more.

Interviews are stressful. Having an experienced advisor with you, someone who has sat through dozens of these and knows where the traps are, changes the dynamic.

What to Do When the First ATO Information Request Lands

Here’s the scenario: you open your email and there’s a message from an ATO officer. They’re conducting a review of your tax affairs. They’d like some information and documents. Could you provide them within the next two weeks?

What do you do?

Do not reply immediately. Do not start gathering files and hitting send.

Your first step is to assess what you’re dealing with:

• Is this an informal request or a formal notice?
• What is the scope of the review: a single issue, a whole year, multiple years, a specific transaction?
• What exactly is being requested? Are the categories clear, or vague and open-ended?
• Do you know why this review is happening, or are you guessing?
• Do you have the documents requested, and where are they located?
• Who in your business needs to be involved in the response?
• Is any of the requested material potentially privileged or sensitive?

You cannot answer these questions on your own. This is the moment to bring in your advisors: your accountant, and depending on the stakes, a lawyer experienced in tax disputes.

Once you’ve taken advice, your next step is to respond to the ATO, but strategically:

• Acknowledge the request promptly (don’t ignore it and hope it goes away)
• If the request is unclear, ask for clarification: what specific issues are under review, what documents are actually needed, why certain categories are relevant
• If the timeframe is unrealistic, explain why and propose a reasonable extension
• Confirm how the documents should be provided (format, delivery method, labelling)

Then, before you produce anything:

• Conduct a thorough review of what you hold, with your advisors
• Identify any material that is clearly privileged or subject to a concession, and flag it
• Consider whether any of the documents create risk if provided without context
• Document what you’re providing, and retain copies

When you produce the documents:

• Provide a cover letter listing what’s been included and noting any material withheld on privilege grounds
• Do not include commentary, explanations, or narrative unless specifically requested
• Keep the tone professional and factual
• Retain evidence of what was sent and when

This disciplined approach achieves two things: it shows cooperation (you responded promptly, engaged constructively, and provided what was required), and it protects your interests (you didn’t over-disclose, you raised privilege properly, and you maintained control of the process).

Most importantly, you made these decisions with advice, not in a panic at 5pm on a Friday.

Can you describe, right now, who in your business would coordinate an ATO information request if one arrived tomorrow? If the answer is “we’d figure it out”, you’re not ready.

When Cooperation and Protecting Your Position Are Not Mutually Exclusive

There’s a myth that responding strategically to ATO information requests means being uncooperative or obstructive.

That’s wrong.

Cooperation means engaging constructively, providing what’s required, meeting deadlines, and treating the process professionally.

It does not mean handing over everything without question, waiving privilege accidentally, or letting an audit drift without clear boundaries.

The businesses that manage audits well understand this balance. They respond promptly, but not carelessly. They provide information, but they check what they’re sending first. They engage with the ATO, but they keep control of the narrative.

The businesses that struggle are usually at one of two extremes: either they provide everything in a panic, hoping compliance will make the audit go away, or they resist reflexively, treating every request as an imposition.

Neither approach works.

The ATO expects businesses to cooperate, and most of the time cooperation is the right strategy. But cooperation on your terms, with advice, and within proper boundaries.

If the audit escalates, if positions harden, if the matter heads towards litigation, the way you handled the early information requests will matter. Documents you provided casually at the start might undermine your position later. Privilege you waived without realising can’t be clawed back.

The time to get this right is at the beginning, not when it’s too late.

When to Escalate: Bringing in Disputes Expertise Early

Not every ATO information request needs a litigation lawyer. Many audits are straightforward, resolve cooperatively, and never escalate.

But some do.

The question is: how do you know which is which, and when do you escalate?

Here are the warning signs:

• The ATO is asking for information that goes far beyond the apparent scope of the review, and won’t explain why
• Formal notices are being issued early, before informal engagement has been given a chance
• The tone of correspondence shifts from cooperative to adversarial
• You’re being asked to attend multiple interviews, or the interviews feel more like interrogations than information-gathering
• The ATO is investigating not just the tax treatment, but your intent, conduct, or integrity
• Penalties are being raised as a possibility
• The matter involves complex or novel legal issues where the ATO’s position is aggressive or untested

If any of these apply, this is not a routine audit. This is a dispute in the making.

At that point, having a lawyer with litigation experience becomes critical. Not because you’re heading to court tomorrow, but because the decisions you make now, the information you provide now, and the positions you take now will shape what happens if the matter does escalate.

A disputes lawyer will help you assess the true risk, protect your position, and engage with the ATO in a way that keeps settlement possible but prepares for the alternative.

Waiting until an amended assessment is issued, or penalties are applied, or the matter is already in litigation, means you’re responding to positions the ATO has locked in. It’s much harder to influence the outcome at that stage.

The right time to get disputes advice is when you first sense the audit is not straightforward. When the questions feel pointed. When the information requests feel strategic, not routine.

That’s the moment to pick up the phone.
