ACN Registration Cost: What It Really Costs In Australia

Thinking about setting up a Pty Ltd company and getting your Australian Company Number (ACN)? It’s a smart move for many small businesses, but it’s normal to wonder what the total “ACN registration cost” actually looks like in practice.

In Australia, registering a company involves more than the government fee. There are one-off setup costs, optional (but often essential) legal documents, and some ongoing ASIC charges you’ll need to budget for.

In this guide, we break down the real cost to register a company in Australia, what drives those costs up or down, and where you can save money without cutting corners. We’ll also cover the key decisions you’ll need to make to set your company up the right way from day one.

What Is An ACN And When Do You Need One?

An Australian Company Number (ACN) is a unique nine-digit number issued by the Australian Securities and Investments Commission (ASIC) when you register a company. Every company in Australia must have an ACN. You’ll use it on invoices, contracts and company documents.

You will only receive an ACN if you register a company (for example, “YourCo Pty Ltd”). If you’re trading as a sole trader or partnership, you won’t have an ACN - you’ll use an Australian Business Number (ABN) instead.

Many founders choose a company structure because it’s a separate legal entity and can provide limited liability protection. If you plan to bring in co-founders or investors, or you want to protect your personal assets as the business grows, registering a company can be a strong foundation. You’ll also need to make sure you meet the Australian resident director requirements before you submit an application.

How Much Does ACN Registration Cost In Australia?

There are several components that make up the “ACN registration cost”. The government fees are the same nationwide, but professional and documentation costs can vary depending on how you set the company up.

1) ASIC Company Registration Fee (Compulsory)

When you register a company, you pay a government fee to ASIC. This fee is indexed annually (it typically increases a little each year), so treat any dollar amount you see online as indicative. Fees also differ depending on the type of company you register, but the standard proprietary limited company (Pty Ltd) is the most common for small businesses.

Because ASIC updates its fees each year, it’s safest to assume an indexed amount and check current costs before you apply. If you’re planning timing or budgeting, be aware of the periodic ASIC fee increase cycle.

2) Optional ASIC Name Reservation Fee

If you want to reserve your proposed company name before you’re ready to lodge the full registration, there’s a separate name reservation fee. This step is optional - many owners go straight to registration once they’ve settled on a name and completed a quick availability search.

3) Professional Service Fees (Lawyer/Provider)

You can register directly via ASIC or through a professional provider. Using a provider can save time and ensure your company is configured correctly (share structure, officers, documents and registers). If you want a done-for-you service with expert guidance, see Sprintlaw’s fixed-fee Company Set Up.

4) Company Governance Documents

• Company Constitution: You can rely on the Corporations Act’s “replaceable rules,” but most businesses adopt a tailored Company Constitution for clarity around director powers, meetings and share rights. This is a one-off setup cost that pays dividends in smoother governance.
• Shareholders Agreement: If there’s more than one owner, a Shareholders Agreement is strongly recommended to manage decision-making, exits, valuations and disputes. This isn’t technically required to register a company, but it’s one of the most important documents you can invest in.

5) Registered Office And Other Admin Costs

Your company must have a registered office address in Australia (where ASIC can serve documents). If you operate from home, this can be your address, but some businesses choose a registered office service for privacy or practical reasons. If that’s you, factor in the provider’s fee.

6) Ongoing ASIC Costs After Registration

Once you’re registered, there’s an annual review fee for proprietary companies. Late lodgements can attract penalties, so it’s worth diarising key dates or engaging a corporate services provider to keep you compliant. If you make changes during the year (like updating officeholders or share structure), there may be additional lodgement fees - for example, changes that used to go on ASIC Form 484 are now made through ASIC’s online portal.

7) Other “Set-Up” Costs To Consider

• Banking and accounting: A separate company bank account is essential. Your accountant may also charge to set up your chart of accounts and systems.
• Brand and IP: If you intend to protect your brand name and logo with trade marks, that’s a separate process and cost to ASIC company registration.
• Insurance: Public liability, professional indemnity or cyber cover may be required depending on your industry.

Putting this together, the “ACN cost” is the ASIC registration fee plus whatever you choose to invest in professional help and core legal documents. Many founders budget for ASIC fees, a constitution and a shareholder agreement, as well as basic startup admin like banking and accounting.

Company Setup Costs Beyond ASIC Fees

The government fee gets you registered, but the documents around your company are what keep it running well. Here’s where businesses commonly invest a little extra upfront to avoid bigger costs later.

Legal Documents And Governance

• Company Constitution: Sets the rules for how your company is run, which can be clearer and more tailored than the default legal rules.
• Shareholders Agreement: Clarifies ownership, voting rights, dividends, deadlocks and exit events between founders and investors.
• Share Structure And Issue: Before you register, it helps to plan how many shares to issue and to whom. If you’re unsure, this guide on how many shares a company can have will help you frame the decision. If you later issue new shares, you might use a Share Subscription Agreement to document the terms of that issue.
• Execution Of Documents: Once the company is live, you can sign contracts under the Corporations Act - this article on signing under section 127 explains what that looks like in practice.

People And Payroll

If you’re hiring, factor in the cost of proper employment paperwork and ongoing compliance.

• Employment Contracts: Use a tailored Employment Contract for each role to set clear terms and conditions.
• Workplace Policies: As you grow, policies around conduct, leave, WHS and technology use keep standards consistent and reduce risk.

Customer, Website And Privacy

• Terms With Customers: If you sell goods or services, your customer terms should comply with the Australian Consumer Law.
• Privacy Policy: If you collect personal information online (even a contact form or mailing list), a compliant Privacy Policy is important and, in many cases, required.

One-Off Vs Ongoing Company Costs

To budget accurately, it helps to separate once-off setup costs from ongoing obligations.

Once-Off Setup Costs

• ASIC company registration fee (and optional name reservation fee)
• Professional service fees (if you use a provider or lawyer)
• Company Constitution and Shareholders Agreement
• Initial banking/accounting setup

Ongoing Costs

• ASIC annual review fee for proprietary companies
• ASIC lodgement fees if you change details (officers, share structure, registered office)
• Accounting, tax returns and BAS (if applicable)
• Employment-related costs (payroll, superannuation, workers compensation insurance)
• Renewals for things like domain names or trade marks (if you register them)

Tip: Build a simple compliance calendar for your company dates. A missed annual review can lead to late fees that are easily avoided. If you’d prefer support, consider engaging a company secretary/corporate compliance service as part of your Company Set Up.

DIY Registration Vs Using A Provider: What’s More Cost-Effective?

You can register a company yourself via the ASIC platform. If you know exactly how you want to structure the company, understand the governance options and have the time, this can be a lower out-of-pocket path.

However, many small businesses prefer a fixed-fee service so they don’t miss critical steps (like getting share allocations right or adopting a suitable constitution). A misstep at formation can be costly to unwind later, especially if you bring in investors or sell the business.

With Sprintlaw’s Company Set Up, we guide you through the key decisions, prepare the core documents, and handle the lodgement so you walk away with your ACN, company records and a clean governance foundation.

Step-By-Step: How To Register A Pty Ltd And Keep Costs Under Control

1) Confirm That A Company Structure Fits Your Plans

Think about how you’ll operate and grow. If you want limited liability, plan to raise capital or bring in co-founders, a company is often the right choice. Make sure you can satisfy the resident director requirement before you proceed.

2) Choose A Name And Check Availability

Search to see if your proposed name is available and not infringing someone else’s brand. If you’re not ready to lodge, you can reserve the name (for a fee). If you go straight to registration, the name is allocated when ASIC approves your application.

3) Decide Your Share Structure

Plan how many shares to issue on day one and to whom (founders, a holding company, a trust, etc.). Consider both control and future flexibility. If you’re unsure, this overview of how many shares a company can have is a helpful starting point.

4) Prepare Your Governance Documents

Adopt a tailored Company Constitution so you’re not relying on generic default rules. If there’s more than one owner, get a Shareholders Agreement in place before money, roles or equity shift - that’s when misunderstandings tend to happen.

5) Lodge The Company Registration

Submit the application with the required details (officers, registered office, share structure, etc.). When ASIC approves it, you’ll receive your ACN and the company’s official record. If you ever misplace it, here’s how to obtain your ASIC Certificate of Registration again.

6) Set Up Your Company Registers And Execution Process

Maintain your company registers (members, officers, share movements). When you sign contracts, you can use the statutory method under section 127 so counterparties can rely on proper execution.

7) Open A Bank Account And Put The Basics In Place

Open a company bank account, connect your accounting system, and arrange any insurance you need. If you’ll be hiring, use a proper Employment Contract and set up payroll and superannuation correctly.

8) Launch With Clear Customer Terms And Privacy

If you sell goods or services, put in place compliant customer terms. If you collect personal information (which most websites do), publish an up-to-date Privacy Policy that reflects what you actually do with data.

9) Calendar Your Ongoing Obligations

Record your annual review date and any licence renewals or reporting periods. Keep an eye on periodic ASIC fee increase adjustments so you’re not surprised by small changes each year.

How To Keep Your Company Registration Budget On Track

• Prioritise the must-haves: Budget for the ASIC fee and at least a constitution; add a shareholders agreement if there’s more than one owner.
• Avoid rework: Spend time upfront on the share structure and governance - changing these later (especially after investment) is more complex and costly.
• Bundle sensibly: A fixed-fee setup that includes lodgement and core documents can be more cost-effective than piecing it together ad hoc.
• Stay compliant: Set reminders for annual reviews and updates to avoid late fees and stress.

Common Questions About ACN Registration Costs

Is an ABN included when I register a company?

An ABN is separate to the ACN. After your company is created, you can apply for an ABN for the company. Depending on how you register, this step can be done in the same workflow, but it’s a distinct registration.

Do I have to reserve my company name?

No - name reservation is optional. Many founders go straight to registration once they’re ready. Reservation can be useful if you need time to finalise documents but want to secure the name.

Can I rely on the replaceable rules instead of a constitution to save money?

You can, but most businesses prefer a tailored constitution for clarity and flexibility. It’s a modest one-off cost that reduces governance ambiguity over the life of the company.

What drives costs up the most?

Beyond the ASIC fee, costs increase when there are multiple founders (because you’ll want a comprehensive shareholders agreement), complex share rights, or when you add professional support for drafting and compliance. These are smart investments if they prevent disputes and rework later.

Key Takeaways

• The “ACN registration cost” is more than the ASIC fee - budget for governance documents, any professional support, and your first annual review.
• A Company Constitution and, where there’s more than one owner, a Shareholders Agreement are foundational documents that help you avoid costly disputes.
• Plan your share structure before you lodge; simple choices early can save expensive changes later when investors come on board.
• Keep on top of ongoing obligations like the ASIC annual review and small indexed fee changes to avoid late penalties.
• If you’d prefer a streamlined and compliant setup, a fixed-fee service can be more cost-effective than DIY rework.
