ASIC Form 484: How To Update Your Company Details

Running a company moves fast - directors change, new shares are issued, names get updated, and offices move. When any of this happens, you’re expected to notify the Australian Securities and Investments Commission (ASIC) promptly and correctly.

That’s where ASIC Form 484 comes in.

In this guide, we’ll unpack what the 484 form is, when you need it, what you can (and can’t) change with it, and how to lodge it properly so you avoid late fees and compliance headaches. We’ll also share practical tips on the resolutions and supporting documents ASIC commonly expects you to keep in your records before you file.

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

ASIC Form 484 (often called “Form 484” or just “the 484 form”) is the standard way companies notify ASIC of most changes to their company details. If you’ve formed an Australian company (Pty Ltd), you have ongoing obligations under the Corporations Act 2001 to keep ASIC up to date. The 484 form is the workhorse for that job.

You use it to tell ASIC about changes such as your registered office, principal place of business, officeholders (directors/secretaries), share structure and shareholdings, and other core company information. Lodging on time matters - ASIC can issue late fees and, in serious cases, take action if changes aren’t notified.

If you’d like a quick overview before diving in, we’ve covered the essentials in our guide on ASIC Form 484.

What Company Changes Can You Lodge On Form 484?

Form 484 is divided into sections so you only complete the parts that apply to your change. Common scenarios for small businesses include:

1) Company Addresses

• Registered office address
• Principal place of business

ASIC requires a physical address in Australia (not a PO box) for your registered office. If you move, that update goes through the 484 form.

2) Officeholders

• Appointment or cessation of a director or company secretary
• Changes to a director’s personal details (name, residential address)

Australia also has specific resident director requirements, so make sure your board composition continues to meet the law after changes.

3) Share Capital And Shareholdings

• Issue of new shares
• Changes to share structure (e.g. creating or reclassifying share classes)
• Transfer of shares between shareholders
• Share cancellations (e.g. buy-backs, forfeiture, capital reductions)

Many events that change who owns what in your company will trigger a 484 lodgement. If you’re moving equity around, check out our practical guide to transferring shares in a private company.

4) Company Name Changes

Changing your company name involves a separate process (you’ll apply for the new name first and pass a resolution). Once approved, the change is recorded with ASIC and you’ll receive a new certificate. While aspects of this can intersect with Form 484, name changes generally follow their own ASIC workflow.

5) Ultimate Holding Company

If your company becomes a subsidiary or stops being one, you’ll use the relevant section of the 484 form to notify ASIC about the ultimate holding company.

There are other niche items, but the above are the ones most small businesses encounter. If you’re unsure which section applies, it’s worth getting tailored advice so the lodgement is right the first time.

Step-By-Step: How To Complete And Lodge Form 484

You can lodge changes electronically via ASIC’s online services or through a registered agent. The process below applies whether you’re completing a paper 484 or following the equivalent prompts online.

Step 1: Identify Exactly What’s Changing

Before touching the form, write down the precise change and the effective date. For example: “Appoint Sarah Lee as director effective 15 May 2025,” or “Issue 100,000 Ordinary shares to NewCo Pty Ltd on 1 July 2025 at $1 per share.” Clear details help you pick the right sections of the form and assemble the right supporting records.

Step 2: Check Your Internal Documents

Your company’s decision-making must follow your Company Constitution (or the replaceable rules if you don’t have a constitution) and, if applicable, your Shareholders Agreement. These documents may set pre-conditions, like pre-emptive rights on share issues, board approval thresholds, or special notice requirements.

If a board or shareholder resolution is required, prepare and pass it first. Keeping consistent records is critical - ASIC can request to see them. A simple way to stay organised is to use a clear Directors Resolution format for decisions that need board approval.

Step 3: Gather The Supporting Information

ASIC will need specific details depending on the change. Common examples include:

• New director’s full name, date of birth and residential address
• Share issue details: class, number, paid/unpaid amounts, consideration, and the issue date
• Share transfer details: seller, buyer, date of transfer, class and quantity
• New registered office or principal business address and the date it takes effect

For share-related changes, ensure your internal registers (members and share register) and Share Certificates line up with what you’re lodging.

Step 4: Complete The Relevant 484 Sections

Form 484 is modular. Only complete the sections that relate to your change. Examples:

• “Change to company details” for addresses
• “Change of officeholders” for director or secretary appointments/cessations
• “Changes to share structure” for share class amendments
• “Changes to members register” for issues, transfers, cancellations

Take care with dates. ASIC relies on your effective date to calculate whether a late fee applies and to determine the legal timing of the change.

Step 5: Lodge And Confirm

Once lodged online, you’ll receive an acknowledgement. Keep a copy of the submitted form or transaction confirmation with your company register. If you use a registered agent, they should send you confirmation and any updated company statements.

Step 6: Update Your Company Registers

ASIC notifications don’t automatically update your internal records. After a change, update your registers (members, options, officeholders), minute books, certificates, and any related agreements. Consistency between ASIC and your internal paperwork is essential for audits, transactions and due diligence down the track.

How Long Do You Have To Lodge Form 484?

In many cases, you have 28 days from the effective date of the change to lodge the 484 form (for example, when appointing or ceasing a director or changing addresses). Late fees apply if you miss the deadline, and they increase the longer you wait.

Some share transactions and complex capital changes have additional requirements and timeframes. If your company is undertaking buy-backs, capital reductions, or creating new classes of shares, speak with a lawyer to ensure the process and timing meet Corporations Act requirements.

Common Mistakes (And How To Avoid Penalties)

Using The Wrong Effective Date

ASIC wants the actual date the change took effect. For a director appointment, that’s the date they consented and the board resolved to appoint them. For a share issue, it’s the date the shares were issued (not when you drafted the paperwork). Pick the wrong date and you can trigger late fees or create inconsistencies.

Forgetting Internal Approvals

Issuing or transferring shares without following your constitution or shareholders agreement can invalidate the transaction or lead to disputes. Always check if pre-emptive rights or special majority approvals apply before you lodge anything.

Misstating Share Class Details

When you create or vary share classes (for example, converting Ordinary shares to Preference shares), ASIC expects the class rights to be clear and consistent with your constitution. This is an area where errors are common - get the drafting right before you lodge the change.

Not Updating Internal Registers

Lodging a 484 is not the end of the job. If your member register, director register, minute book, and share certificates don’t mirror what you told ASIC, you can run into problems during financing, resale or investor due diligence.

Leaving It Too Late

Late fees with ASIC add up quickly. As soon as a change occurs, put the 484 lodgement on your to-do list. If you realise you’ve missed a deadline, lodge as soon as possible - fees escalate over time.

What Documents Should You Have In Place Before Lodging?

ASIC often doesn’t ask you to attach these documents to a standard 484 lodgement, but you’re expected to have them in your company records. They’re also essential for clean governance and future transactions.

• Directors’ Resolution: The board’s formal approval of the action (appointment, issue, transfer, change of address). A clear Directors Resolution helps keep your file tidy.
• Consent To Act (for officeholders): Written consent from any new director or company secretary.
• Share Issue/Transfer Instruments: For issues, keep a board resolution and any subscription letter or application forms. For transfers, retain a signed transfer form and consideration details - our guide to transferring shares outlines the core steps.
• Updated Registers & Certificates: Update the members register and issue Share Certificates for new holders or changes.
• Company Constitution & Share Class Terms: Ensure your Company Constitution permits the change (and is updated if you introduce new classes).
• Shareholders Agreement: Where you have one, confirm any pre-emptive rights, consent thresholds and process steps are followed - your Shareholders Agreement generally sets the ground rules between owners.

For more complex corporate actions (e.g. buy-backs, selective share cancellations or capital reductions), you’ll likely need additional notices, solvency statements and filings. If you’re in that territory, it’s worth getting advice early to keep the process compliant and efficient.

FAQs: Practical Questions About Form 484

Do I Still Use “Form 484” If I Lodge Online?

Yes, in practice the online portals guide you through the same data fields that appear in Form 484. Whether you submit a paper form or file online, you’re notifying ASIC of the same prescribed information.

Can I Fix Errors After Lodging?

If you spot a mistake, act quickly. Depending on the error, you may be able to lodge a corrected 484 or contact ASIC to rectify the record. You should also correct your internal registers and minutes so everything aligns.

Do I Need To Tell ASIC About Internal Role Titles?

Not unless the person is an official officeholder (director or company secretary). Internal job titles like “CEO” or “General Manager” aren’t officeholder roles unless that person is also appointed as a director or secretary with ASIC.

What If We’re Creating A New Share Class?

Make sure class rights are documented properly in your constitution before you lodge. If you’re introducing different dividend, voting or liquidity rights, this usually involves updating the constitution and passing shareholder resolutions describing the new class. Our guide to different classes of shares explains the concepts in plain English.

We’re Issuing Shares To An Investor - Is Form 484 Enough?

You’ll notify ASIC via the 484, but you also need the right transaction documents (subscription letter or share sale agreement), board/shareholder approvals, and updated registers. In some deals, you might also vary existing investor rights or update your cap table rules via your constitution or shareholders agreement.

Best Practice Tips For Smooth 484 Lodgements

• Capture the change in writing immediately: As soon as a decision is made (or a transaction completes), draft the resolution and note the effective date while it’s fresh.
• Align ASIC and internal records: The details you lodge should match your minutes, registers and certificates word-for-word.
• Standardise your templates: Using consistent resolution and register templates reduces rework and prevents errors in future lodgements.
• Keep a change log: A simple spreadsheet of effective dates, what changed, who approved it, and when it was lodged will save you time at audit or due diligence.
• Plan ahead for share changes: Equity moves touch many documents. Confirm your constitution and Shareholders Agreement support the change before you announce anything to investors or staff.

Key Takeaways

• ASIC Form 484 is the primary way companies notify ASIC of changes to addresses, officeholders, and share capital/shareholdings.
• Get your internal house in order first: pass the right resolutions, check your Company Constitution and Shareholders Agreement, and prepare accurate details and dates.
• Only complete the sections of the 484 that apply to your change, and lodge within the required timeframes to avoid late fees.
• For share issues, transfers or class changes, ensure your registers, Share Certificates and ASIC lodgements all match.
• Complex corporate actions (like buy-backs or creating new share classes) benefit from early legal support to get the process and paperwork right.
• Keep clear records of what changed, when it changed, who approved it, and when it was lodged - it will pay off at audit, investment or exit.
