ASIC Form 484: How To Update Your Company Details

Running a company in Australia means your details will change from time to time - new directors, updated addresses, or issuing shares as you grow. The Australian Securities and Investments Commission (ASIC) needs to know about many of these changes, and the way you tell ASIC is by lodging ASIC Form 484.

If you’re a busy small business owner, the good news is that Form 484 is straightforward once you understand what it covers, when it’s due, and how to prepare it correctly. In this guide, we’ll walk through the essentials so you can keep your company records clean and compliant without the stress.

What Is ASIC Form 484 And When Do You Use It?

ASIC Form 484 is the main form companies use to notify ASIC of changes to company details. You’ll generally lodge it online through ASIC’s systems or via your registered agent, and it covers most day-to-day updates a proprietary company needs to report.

At a high level, you use ASIC Form 484 to tell ASIC about:

• Changes to officeholders (appointing or ceasing a director or secretary, or updating their details)
• Changes to addresses (registered office, principal place of business, or officeholder addresses)
• Changes to share structure and member (shareholder) details, including issuing, transferring, or cancelling shares
• Changes to the ultimate holding company (if applicable)

For most items, there’s a 28-day window from the date the change happens to lodge the 484. If you miss that deadline, late fees can apply and escalate the longer you wait. Keeping on top of these updates is part of good company governance - and it protects you from avoidable penalties.

Which Company Changes Go On A 484?

Company Details And Addresses

Form 484 covers changes to:

• Registered office address
• Principal place of business
• Officeholder residential addresses (ASIC keeps residential addresses for directors and secretaries, even if not publicly displayed)

Address changes must be reported promptly. If you move and don’t update ASIC, important notices (including annual review documents) could go to the wrong place, causing compliance headaches.

Officeholders: Directors And Secretaries

You must notify ASIC when you appoint or cease a director or company secretary, or when their details change. Before you appoint someone, make sure they consent and that you have the right board or shareholder approvals in place, depending on your company’s rules.

Share Structure And Members (Shareholders)

This is the part many small companies use most. You’ll use Form 484 to:

• Issue new shares (for example, to a new co-founder or investor)
• Transfer shares between existing shareholders or to a new shareholder
• Cancel or buy back shares (where permitted and properly approved)
• Update details of members (names, addresses) and their holdings

When you change your share structure, check both your Company Constitution and any Shareholders Agreement for rules about approvals, pre-emptive rights (rights of first refusal), and share classes. Lodging the 484 doesn’t replace those internal requirements - it reports the outcome to ASIC after you’ve properly authorised the change.

Ultimate Holding Company

If your company becomes a subsidiary (or ceases to be one), you need to notify ASIC by updating the ultimate holding company information via Form 484. This sometimes happens after group restructures or when investors acquire control.

Deadlines, Fees And Penalties: What Small Companies Should Know

ASIC expects timely updates, and Form 484 is no exception. The general rule is to lodge within 28 days of the change taking effect. In practice, many businesses prepare the authorising resolutions first and then lodge straight away - a simple process if you keep your paperwork in order.

Missing the deadline triggers late fees that increase the longer the form remains outstanding. Persistently out-of-date records can also raise red flags in due diligence or banking reviews, and can create friction when you need an updated ASIC Certificate of Registration or extract to prove current details.

It’s far easier (and cheaper) to lodge on time than to untangle late lodgements. A practical tip is to set calendar reminders when you sign board minutes or share transfer forms - if the date of the resolution is 1 March, aim to lodge the 484 no later than 29 March.

Step-By-Step: How To Prepare And Lodge A 484

1) Confirm Authority And Approvals

Start by checking your internal rules. Does your Company Constitution require a specific type of approval for appointing directors or issuing shares? Do pre-emptive rights apply under your Shareholders Agreement before shares can be offered to an outsider?

Get your approvals in writing via board or member minutes. A clear Directors Resolution or shareholder resolution will record what’s being approved, who consented, and the effective date. If physical or electronic signing is needed, make sure execution follows section 127 to avoid questions later.

2) Assemble Accurate Details

Gather the specific data ASIC needs for the change, such as:

• Full legal names and addresses for new officeholders or members
• Dates of appointment/cessation or address changes
• Share class, number of shares issued or transferred, and consideration (if any)
• Updated details of the ultimate holding company, if applicable

Small inconsistencies (for example, spelling differences across documents) can slow down things later, so double-check everything as you go.

3) Update Your Internal Registers And Certificates

Companies must maintain a register of members and, in many cases, a register of option holders and officeholders. Update these registers to reflect the change, and issue new share certificates where relevant. If you’re handling a transfer of shares, make sure you have a properly executed transfer form and that any stamp duty requirements (in the relevant state/territory) are addressed.

4) Lodge Form 484

Once your resolutions and registers are in order, lodge the 484 online through ASIC’s channels (or ask your registered agent or accountant to lodge on your behalf). The person lodging should be an authorised officeholder or agent who can certify the changes are accurate.

Keep a copy of the lodged form, ASIC confirmation, and all supporting paperwork with your company records. Good record-keeping saves time during audits, finance applications and future transactions.

5) Notify Stakeholders And Keep Systems In Sync

After ASIC is updated, make sure your other records match. Update your bank, insurers, business partners, and any licences or permits if the change affects those records. Consistency across systems helps avoid confusion when third parties run company searches or ask for verification documents.

Common Scenarios And Practical Tips

Bringing In A New Co‑Founder Or Investor

When you issue new shares, check whether existing shareholders have first rights to buy (pre‑emptive rights) and whether the new issue changes control or triggers specific provisions in your Shareholders Agreement. Prepare the board/shareholder resolutions, update the member register, issue share certificates, and lodge Form 484 within 28 days.

Transferring Shares Between Existing Owners

Share transfers are common when an owner exits or reallocates equity. Confirm transfer restrictions in your Company Constitution, obtain duly executed transfer forms, update registers and certificates, then lodge the 484. If you’re unsure whether a particular transfer needs extra approvals, it’s wise to document a short board resolution to confirm compliance before you lodge.

Appointing Or Resigning A Director

Have the director consent (for appointments) or a signed resignation letter (for cessations). Approve the change at a board meeting (or by circular resolution), update your officeholder register and lodge the 484. Don’t forget to collect and securely store identity information for new officeholders - it helps keep your records consistent if you ever need to verify details.

Changing Your Registered Office Or Principal Place Of Business

Make sure you have the right to use the new registered office address (for example, consent from your accountant if you use their address). Update your internal records and external documents (invoices, website footer), then lodge the change via Form 484. Keeping your address current ensures you receive ASIC’s annual review packages and other notices on time.

Restructuring Or Becoming A Subsidiary

If your ownership structure changes and you become (or cease to be) a subsidiary, update the ultimate holding company on a 484. It’s also a good moment to review whether your governance documents still fit your structure - for example, you may need to refresh delegations or board protocols to reflect your group setup.

A Note On Documentation And Execution

Form 484 reports a change - it doesn’t create it. The change is created by your resolutions, agreements, and proper execution. Ensure documents are signed correctly in line with section 127 and your constitution, and keep everything filed together so you have a clear audit trail.

Avoiding Common Mistakes

• Missing the 28‑day deadline: diarise lodgements when you sign your resolutions.
• Skipping internal approvals: check constitutional rules and pre‑emptive rights before you issue or transfer shares.
• Not updating internal registers: ASIC records and your member/officeholder registers should always match.
• Inconsistent names or addresses: use full legal names and check spelling across all documents - this helps when banks or partners check your records or request an updated ASIC Certificate of Registration.
• Overlooking related updates: notify your bank, insurers, and key partners to keep their records in sync with ASIC.

Key Takeaways

• ASIC Form 484 is how you notify ASIC of changes to company details - including officeholders, addresses, share structure, members, and the ultimate holding company.
• Most updates must be lodged within 28 days of the change. Late lodgements can attract escalating fees, so diarise important dates and lodge promptly.
• Always get your internal approvals right first: check your Company Constitution, follow any pre‑emptive rights in your Shareholders Agreement, and record decisions with a clear Directors Resolution.
• Keep your internal registers and share certificates up to date, and ensure documents are executed correctly under section 127.
• For share movements, make sure the paperwork behind any transfer of shares or new issue is complete before you lodge the 484.
• Consistent, timely updates across ASIC and your own records reduce risk, support clean due diligence, and keep your small company running smoothly.
