Australia, with its stable economy, transparent business environment, and skilled workforce, presents a compelling opportunity for U.S. entrepreneurs looking to expand their global footprint. Establishing an Australian subsidiary company can be a straightforward process, offering numerous benefits.
This detailed guide will walk you through the essential steps and considerations for registering your company Down Under.
1. Choosing Your Business Structure

For U.S. businesses looking to establish a significant and long-term presence in Australia, the most common and recommended structure is a Proprietary Limited (Pty Ltd) company. This structure establishes an Australian subsidiary company, a distinct legal entity separate from your U.S. parent company. This separation offers distinct advantages, primarily limited liability, meaning the parent company’s assets are generally protected from the subsidiary’s debts and obligations.
While other options exist, such as a branch office (which is not a separate legal entity and leaves the foreign parent company liable for all debts) or a representative office (for non-income generating activities), the Australian subsidiary company registration as a Pty Ltd is typically the most robust choice for active business operations.
2. Key Requirements for Your Australian Subsidiary Company

Before you dive into the registration process, understand the fundamental requirements for establishing your Australian subsidiary company:
Company Name
Choose a unique company name that complies with Australian naming conventions and isn’t already registered. You’ll need to check its availability with the Australian Securities and Investments Commission (ASIC).
Registered Office Address
Your Australian subsidiary must maintain a registered office with a physical address in Australia that operates during designated business hours (usually 10 am to 12 pm and 2 pm to 4 pm on weekdays). This location serves as the official address for receiving correspondence and legal documents. Many businesses opt for virtual office services to satisfy this requirement.
Resident Director
A crucial requirement is that your Australian subsidiary company must have at least one director who ordinarily resides in Australia. This director plays a vital role in ensuring compliance with local regulations. If you don’t have a suitable individual, professional resident director services are available. All directors, including international ones, must obtain a Director Identification Number (DIN). For non-resident directors, the DIN application is a paper-based process that can take 3-12 months, so plan accordingly.
Shareholders
An Australian proprietary limited company must have at least one shareholder and a maximum of 50 non-employee shareholders. There’s no minimum share capital requirement to form an Australian subsidiary; even AUD 1 can be sufficient.
Company Constitution
You’ll need a company constitution, which outlines how the company will be governed and operated. This is essentially the rulebook for your Australian subsidiary company.
3. The Registration Process: Step-by-Step

The primary body responsible for company registration in Australia is the ASIC. Here’s a general outline of the steps for your Australian subsidiary company registration:
Apply for a Director Identification Number
As mentioned, all directors, including non-resident ones, must obtain a DIN, a unique 15-digit identifier. For non-residents, this is a paper application that can take time.
Choose and Reserve Your Company Name
Before formally registering, confirm the availability of your chosen name through ASIC.
Prepare Required Documents
Gather all necessary documents, including the company constitution, identification for directors and shareholders, and proof of your registered Australian address. For a foreign parent company establishing an Australian subsidiary, you’ll also need a certified copy of the parent company’s certificate of registration/incorporation and its constitution.
Register with ASIC
You can register your Australian subsidiary company directly through the ASIC website by completing Form 201. Alternatively, you can engage a private service provider (PSP) to manage the entire application process, often with faster processing due to direct access to ASIC’s systems. Upon successful registration, ASIC will issue you an Australian Company Number (ACN), a unique nine-digit identifier for your company, and a certificate of registration.
Apply for an Australian Business Number (ABN)
Once you have your ACN, you’ll need to apply for an Australian Business Number from the Australian Taxation Office (ATO). The ABN is an 11-digit number that uniquely identifies your business for all its tax and government interactions. It’s crucial for invoicing, claiming Goods and Services Tax (GST) credits (if registered for GST), and avoiding Pay As You Go (PAYG) withholding tax on payments received. While the ACN identifies your registered company, the ABN identifies your business for broader tax and commercial purposes.
Register for Taxes (TFN, GST, PAYG)
- Tax File Number (TFN): Your Australian subsidiary company will need a TFN for tax purposes. This is generally obtained alongside your ABN.
- Goods and Services Tax (GST): If your Australian subsidiary company is projected to have an annual turnover of AUD 75,000 or more, you are legally required to register for Goods and Services Tax (GST). This is a 10% tax that applies to most goods and services sold in Australia.
- PAYG Withholding Tax: If your Australian subsidiary company plans to employ staff, you’ll need to register for PAYG withholding tax to deduct income tax from employee wages.
Open an Australian Business Bank Account
A dedicated business bank account in Australia is essential for managing your Australian subsidiary company’s finances, including payroll and other transactions.
Obtain Necessary Licenses and Permits
Depending on your industry and specific business activities, your Australian subsidiary company may require additional licenses and permits from federal, state, or local authorities. The Australian Business License and Information Service (ABLIS) can help you identify these.
4. Ongoing Compliance and Obligations
Registering your Australian subsidiary company is just the first step. Ongoing compliance is crucial to avoid penalties and ensure smooth operations:
ASIC Lodgments and Annual Review Fees
Your Australian subsidiary company is required to keep its company details current with ASIC and submit an annual return. Annual review fees are also applicable.
Tax Compliance
The standard corporate tax rate in Australia is set at 30%. However, eligible “base rate entities”—companies with an aggregated turnover of less than AUD 50 million—may qualify for a reduced tax rate of 25%.
Employment Laws
If you plan to hire employees for your Australian subsidiary company, you must comply with Australia’s comprehensive employment laws, primarily governed by the Fair Work Act 2009. This includes adherence to the National Employment Standards (NES) regarding minimum wages, working hours, leave entitlements, and superannuation (pension) contributions. Anti-discrimination laws and Work Health and Safety (WHS) regulations are also paramount.
Maintain Records
Your Australian subsidiary company must maintain accurate financial records, including a share registry, minute book, and other company registers.
Display Company Information
The registered name of your Australian subsidiary company, along with its ACN, must be displayed at your business premises and on all public documents, including invoices and official correspondence.
5. Intellectual Property Protection
Protecting your intellectual property (IP) is vital when expanding into a new market. Australia has a robust IP framework that aligns with international standards. You can safeguard your trademarks, patents, copyrights, and designs within Australia. It’s advisable to register your IP rights in Australia according to local requirements. Organizations like IP Australia and the Department of Foreign Affairs and Trade (DFAT) offer resources and guidance on international IP protection.
Concluding Remarks
Establishing an Australian subsidiary company offers U.S. entrepreneurs a fantastic gateway to the Asia-Pacific market.
