Running a company in Australia comes with a few non‑negotiables. One of the most important early steps is appointing a public officer - the person who officially represents your company in tax matters with the Australian Taxation Office (ATO).
If you’ve just incorporated or you’re about to start trading in Australia, it’s important to get this right. In this guide, we’ll explain what a public officer does, who can take on the role, how and when to appoint one, what happens if things change, and practical tips to stay compliant and organised from day one.
This is general information to help you understand your obligations. Everyone’s situation is different, so it’s a good idea to get tailored legal and tax advice for your company’s circumstances.
What Is a Public Officer?
A public officer is your company’s authorised representative for tax purposes. Under the Income Tax Assessment Act 1936 (particularly section 252), most companies carrying on business or deriving income in Australia must appoint a public officer to deal with the ATO on the company’s behalf.
Think of the public officer as the official “point person” for the ATO. They receive notices, help ensure your company’s tax obligations are met, and are the contact the ATO expects to hear from about the company’s tax affairs.
Key points to keep in mind:
- The public officer acts for the company in its tax dealings (they’re not a separate tax adviser by default).
- The company remains responsible for its own tax compliance and liabilities.
- If your company operates in Australia, you generally need to appoint within set timeframes (more on timing below).
Who Can Be Appointed And What Do They Do?
Eligibility
To be appointed as a public officer, the person must:
- Be at least 18 years old; and
- Ordinarily reside in Australia; and
- Be capable of understanding and carrying out the responsibilities of the role.
Many companies appoint a director, company secretary, senior finance employee, or an experienced external professional. It’s common to choose someone already closely involved in the company’s financial reporting or tax processes.
Typical Responsibilities
The public officer’s responsibilities will vary depending on the size and complexity of your company, but often include:
- Acting as the primary contact with the ATO for the company’s tax matters.
- Helping ensure lodgements are made on time (for example, income tax returns and other required forms).
- Facilitating accurate record‑keeping and supporting documentation for the company’s tax position.
- Receiving ATO correspondence and ensuring it’s escalated and actioned internally.
It’s important to note that while the public officer facilitates compliance, the company itself is generally the party liable for penalties if obligations aren’t met. In some cases, an individual could face consequences for their own conduct, but it’s not correct to assume the public officer automatically becomes personally liable for the company’s tax debts.
When Do You Need To Appoint - And How Does It Work?
Timing Requirements
Companies are usually required to appoint a public officer within three months of either:
- Starting to carry on business in Australia; or
- Deriving income in Australia.
If the role isn’t filled within this timeframe, the ATO can impose penalties, including amounts that may accrue for each day the requirement remains outstanding. The safest approach is to make the appointment part of your day‑one setup checklist so you don’t miss the deadline.
Practical Steps To Appoint
The legislation requires you to appoint and notify the ATO. The exact internal process isn’t prescribed, but best practice is to:
- Have the board or directors formally approve the appointment (for example, by passing a resolution). Using a simple Directors Resolution Template can help you record the decision clearly.
- Obtain written consent from the person accepting the role (this keeps your records clean and avoids disputes).
- Notify the ATO of the appointment within the required timeframe. Keep a copy of the notification and any ATO acknowledgement with your company records.
If you’re setting up your company now, it can be efficient to sort this alongside other corporate housekeeping, such as adopting a Company Constitution and confirming your resident director arrangements (see our guide on Australian resident director requirements).

Changing Or Removing A Public Officer
Changes happen. If your public officer resigns, moves overseas, can no longer perform the role, or you decide to appoint someone else, you’ll need to update the ATO promptly.
When You Must Update
Common scenarios that trigger an update include:
- Resignation or retirement of the public officer.
- Loss of Australian residency (they no longer ordinarily reside in Australia).
- Incapacity, death, or another event that means they cannot act.
- A company decision to replace the public officer.
In each case, notify the ATO of the change within 28 days and keep internal records of the transition.
Practical Replacement Steps
- Confirm the outgoing officer’s end date and ensure they hand over key information and ATO correspondence.
- Approve the replacement (for example, by a directors’ resolution) and obtain their written consent.
- Notify the ATO of the new appointment within the required timeframe.
This is also a good time to tidy up your corporate records. If you have multiple stakeholders, make sure your governance documents - such as a Shareholders Agreement - clearly set out who can approve appointments like this and how decisions are made.
Are There Any Exemptions Or Special Cases?
Most companies that carry on business or derive income in Australia need a public officer. There can be limited circumstances where an exemption applies, for example where the Commissioner of Taxation grants permission. In practice, exemptions are narrow, and even if your company’s Australian‑sourced income is limited or passive, it’s important to check the specific rules that apply to your situation.
If you’re unsure whether your company must appoint a public officer, or you operate through a group with overseas entities, it’s worth getting tailored advice. The cost of sorting this early is almost always lower than dealing with late‑appointment penalties or ATO follow‑ups later.
Staying Compliant: Practical Tips That Make Life Easier
Once you’ve appointed your public officer, keep your processes simple and consistent so compliance becomes routine rather than a scramble. A few practical tips:
1) Build Clear Internal Processes
- Centralise ATO mail and email so nothing slips through the cracks.
- Set calendar reminders for lodgement dates and periodic internal reviews.
- Document who does what (for example, finance prepares returns, the public officer reviews and authorises).
2) Keep Your Records In Order
- Maintain a clean register of appointments, consents and ATO notifications with your corporate records.
- If a third party (like a tax agent) interacts with the ATO on your behalf, ensure their authority is properly documented. For general business interactions, many companies also use an Authority To Act form so there’s no confusion about who can communicate or provide instructions.
3) Align Your Corporate Governance
- Make sure your company’s governing documents reflect how appointments are made and who can approve them. If you’re updating your governance, consider whether your Company Constitution needs a refresh.
- If you operate with co‑founders or investors, your Shareholders Agreement should set out decision‑making processes for roles like the public officer.
4) Don’t Forget The Rest Of Your Compliance Stack
Appointing a public officer is one part of your compliance picture. Make sure your broader legal and operational essentials are covered, too:
- Employment: If you have staff, issue the right Employment Contract and set clear workplace policies.
- Privacy and data: If you collect any personal information (for example, customer or employee details), publish a compliant Privacy Policy and stick to it in practice.
- Signing company documents: Ensure you’re executing documents properly under company law - see our explainer on signing documents under section 127.
The theme here is simple: a few small habits (clear approvals, tidy records, and timely ATO notifications) will keep your company on the front foot, reduce stress at lodgement time, and lower the risk of penalties.
Key Takeaways
- Most companies that carry on business or derive income in Australia must appoint a public officer under the Income Tax Assessment Act 1936.
- The public officer is your company’s official ATO contact for tax matters; they help facilitate compliance, but the company remains responsible for its tax obligations.
- Appoint within three months of starting business or deriving income in Australia, and notify the ATO - late appointments can attract penalties.
- When the role changes (for example, resignation or loss of residency), appoint a replacement and notify the ATO within 28 days.
- Treat the board resolution and written consent as best‑practice internal steps and keep copies with your records.
- Build simple compliance habits - centralise ATO mail, diary key dates, keep clean records, and ensure your core documents like your Company Constitution, Shareholders Agreement, Employment Contract and Privacy Policy are in place and up to date.
