Expanding Your US Company to Australia: Complete Guide [2026]

If you have asked ChatGPT or any AI tool “how do I set up a business in Australia from the US?”, you probably got a list of steps that looks straightforward on paper but leaves out the hard parts: which entity structure avoids double taxation, how to satisfy the resident director requirement without flying someone to Sydney, what actually happens when you try to open an Australian bank account remotely, and how long it all takes.

This guide gives you the real answers, with exact costs, exact timelines, and the specific legislative references behind every requirement. It is written by the team that does this work every week for US companies ranging from two-person startups to NYSE-listed enterprises.

Week-by-Week Setup Timeline: US Company to Operational in Australia

Here is the actual process, based on hundreds of US company setups we have completed. Some steps run in parallel. Total elapsed time: 2 to 4 weeks for most companies, with an expedited option of 5 business days.

Week 1: Entity Formation and ASIC Registration

Week 2: Tax Registrations and Banking

Weeks 3-4: Employment and Operations

Expedited timeline: We have completed the full process (company registration, ABN/GST, resident director, bank account facilitation) in as few as 5 business days for US companies with urgent hiring deadlines.

Subsidiary vs Branch: Decision Framework for US Companies

This is the first structural decision and it affects your tax position, liability exposure, and how Australian clients perceive you. For a detailed comparison, see our subsidiary vs branch guide.

Our recommendation for most US companies: A Pty Ltd subsidiary under a US C-Corporation parent. This gives you limited liability, a clean corporate structure for both jurisdictions, and access to the 5% dividend withholding rate under the US-Australia DTA.

The LLC Translation Problem

This catches many American businesses off guard. The ATO does not recognise the US LLC as a pass-through entity. Under Division 830 of the Income Tax Assessment Act 1997, your LLC may be classified as a “foreign hybrid,” creating a mismatch where Australia taxes it as a company (25-30%) while the US treats it as a pass-through. The result can be effective double taxation and lost treaty benefits.

The fix: If your US entity is an LLC, incorporate your Australian Pty Ltd under a US C-Corporation parent (not the LLC directly). This provides clean tax treatment in both jurisdictions and preserves your DTA benefits.

Tax Structure: What a US Company Actually Pays in Australia

Corporate Tax

• 25% corporate tax rate for base rate entities (aggregated turnover under $50M AUD). Most US companies entering Australia qualify.
• 30% rate for companies with turnover above $50M AUD.
• Australia taxes your subsidiary on Australian-sourced profits only.

US-Australia Double Tax Agreement: Key Rates

Transfer Pricing

Any transactions between your US parent and Australian subsidiary (management fees, IP licensing, intercompany loans, shared services) must be priced at arm’s length under Australia’s Subdivision 815 rules and OECD guidelines. Both the ATO and IRS scrutinise these arrangements. Penalties for non-compliance reach up to 50% of the tax shortfall. Prepare transfer pricing documentation from day one.

GST (Goods and Services Tax)

Australia’s GST is a 10% value-added tax on most goods and services. Your subsidiary must register for GST if annual turnover exceeds $75,000 AUD (we recommend registering regardless, so you can claim input tax credits). BAS (Business Activity Statements) are lodged quarterly or monthly. For a detailed breakdown, see our GST guide for foreign companies.

US-Side Tax Considerations

Your Australian Pty Ltd will be a Controlled Foreign Corporation (CFC) under US tax law. Key implications:

• Subpart F income: Passive income (interest, dividends, royalties) earned by the subsidiary may be taxable in the US even before distribution. Active business income is generally not caught.
• GILTI (Global Intangible Low-Taxed Income): Applies to CFC income, but Australia’s 25-30% corporate rate generally exceeds the effective GILTI threshold, making it manageable with foreign tax credit planning.
• Foreign tax credits: Both Australian corporate tax and withholding tax paid can be credited against US federal tax, preventing double taxation.

Employment Setup: EoR vs Direct Hiring

US companies have two paths to employing people in Australia. For a full comparison, see our EoR vs direct hiring guide.

Key Australian Employment Differences from the US

At-will employment does not exist in Australia. Every US company needs to understand these differences before hiring:

• Minimum notice periods: 1-5 weeks depending on tenure (longer for employees over 45)
• Unfair dismissal protection: Available after 6 months (12 months for small businesses under 15 employees)
• Redundancy pay: 4-16 weeks depending on tenure if a role is genuinely eliminated
• Superannuation: 12% of ordinary time earnings, paid by the employer on top of salary. From 1 July 2026, must be paid at the same time as wages (currently quarterly is permitted)
• Annual leave: 4 weeks per year (5 for shift workers), plus 10 days personal/carer’s leave
• Modern Awards: 121 industry-specific Awards set minimum pay rates, overtime, penalties, and allowances. See our Modern Award compliance guide.
• Workers’ compensation: Mandatory insurance in every state, obtained before first hire

Do not use US employment contract templates. They are not legally compliant in Australia. We prepare Australian-law employment contracts as part of our setup service.

Resident Director Requirement: Section 201A

Under Section 201A of the Corporations Act 2001, every Australian proprietary company must have at least one director who ordinarily resides in Australia. This is not optional. The penalty for non-compliance is $7,825 per day (5 penalty units at $330 each for 2025-26, applied as a daily contravention).

For US companies that do not have anyone on the ground in Australia, a professional resident director service satisfies this requirement immediately. Our resident directors are experienced compliance professionals who:

• Meet the s201A ordinary residence requirement
• Sign ASIC forms and regulatory documents
• Attend to director obligations under the Corporations Act
• Are covered by professional indemnity insurance

Cost: From $6,000/yr + GST. This is a fraction of what it costs to relocate a US executive to Australia or hire a local director independently.

FIRB Thresholds for US Companies (2026)

The Foreign Investment Review Board (FIRB) screens foreign investments in Australia. Thanks to the Australia-United States Free Trade Agreement (AUSFTA), US investors enjoy significantly higher thresholds than investors from most other countries.

What this means for you: If you are establishing a new Australian subsidiary (which is a greenfield investment), you do not need FIRB approval regardless of investment size. FIRB only applies if you are acquiring an existing Australian business or certain types of real property. Sensitive sectors include defence, telecommunications, transport, media, and critical minerals.

Banking: Opening an Australian Business Account from the US

This is consistently the most frustrating step for US companies. Australian banks have rigorous KYC (Know Your Customer) and AML (Anti-Money Laundering) requirements for foreign-owned entities, and the process is not designed for remote applicants.

Big Four Banks Comparison

Without a facilitated introduction and pre-prepared documentation, the bank account process can take 4-8 weeks and multiple rounds of document requests. With our banking support service, we prepare all KYC documentation upfront and provide a direct introduction, typically reducing this to 5-14 business days.

Year 1 Cost Breakdown for a US Company

Here is a realistic budget for a US company establishing and operating an Australian Pty Ltd subsidiary in Year 1. All amounts in AUD with approximate USD equivalents (at 1 AUD = 0.65 USD).

One-Time Setup Costs

Annual Ongoing Costs

Per-Employee On-Costs (Above Base Salary)

Total employer on-costs: Budget 15-25% above base salary in Australia, compared to the typical 8-12% (FICA, FUTA, state unemployment) in the United States.

Realistic Year 1 total (entity costs only, before payroll): $10,000-$18,000 AUD (~$6,500-$11,700 USD). Compare this to the $20,000-$50,000+ a corporate law firm typically charges just for entity formation advice and ASIC filing.

What We Handle vs What You Still Need

We believe in being direct about what is and is not in our scope. Here is exactly what AusBusinessRegister.com.au covers and where you will need other advisers.

In practice, most US companies setting up a standard Australian subsidiary do not need a corporate lawyer at all. The entity formation, ASIC registration, tax registrations, resident director, and compliance are all handled by us. You only need additional advisers if your situation involves regulated industries, complex IP transfers, or significant M&A activity.

Permanent Establishment Risk: Why You Cannot Just “Test” Australia Informally

Some US companies try to operate in Australia without registering an entity, using contractors or having US employees work remotely from Australia. This creates permanent establishment (PE) risk under both the US-Australia DTA and Australian domestic law.

If the ATO determines your US company has a PE in Australia (through a fixed place of business, a dependent agent concluding contracts, or employees working in-country beyond 183 days), your US company’s profits attributable to that PE become taxable in Australia. You also face penalties for failing to register as a foreign company under s601CD of the Corporations Act.

The cleaner path: Establish a proper entity. It costs less than the tax risk and provides a legitimate platform for hiring, invoicing Australian clients, and building your APAC presence.

Case Study: US SaaS Company Operational in 5 Days

A San Francisco-based enterprise SaaS company (Series A, ~45 US employees) needed to hire an Australian Country Manager who had given them a two-week decision window. Their CFO estimated a DIY approach would require 40-60 hours of executive time and $20,000-$30,000 in legal fees.

By Week 2, they had onboarded their first Australian employee. Within 12 months: 8 employees, $1.8M in converted Australian revenue, and a clean compliance record that supported their Series B due diligence.

Frequently Asked Questions: US Companies Expanding to Australia

Can a US LLC operate directly in Australia?

Technically yes, by registering as a foreign company (ARBN). But it creates serious tax complications. The ATO may classify your LLC as a company (taxed at 25-30%) while the IRS treats it as a pass-through. This mismatch can cause effective double taxation and lost treaty benefits. For most US companies, the recommended structure is an Australian Pty Ltd subsidiary under a US C-Corporation parent. This gives clean tax treatment in both jurisdictions.

Do I need FIRB approval to set up an Australian subsidiary?

Almost certainly no. If you are establishing a new business (greenfield investment), you are exempt from FIRB screening regardless of investment size. Under AUSFTA, even US acquisitions of existing non-sensitive Australian businesses are exempt below $1,498M AUD. FIRB only applies if you are acquiring an existing business in a sensitive sector (defence, telecoms, transport, media, critical minerals) or buying Australian real estate.

How much does it cost to set up a company in Australia from the US?

Entity formation starts from $900 AUD (~$585 USD) for Pty Ltd registration including constitution. Add ABN/GST registration ($450 AUD), resident director (from $6,000/yr + GST), and registered office ($600/yr) for the essentials. Realistic Year 1 all-in cost for entity setup and compliance: $10,000-$18,000 AUD (~$6,500-$11,700 USD). A corporate law firm typically charges $20,000-$50,000+ for the same scope.

Do I need an Australian resident director?

Yes. Section 201A of the Corporations Act requires at least one director who ordinarily resides in Australia. The penalty for non-compliance is $7,825 per day. Our resident director service (from $6,000/yr + GST) satisfies this requirement immediately without needing to relocate a US executive or find a local hire.

How long does it take to register a company in Australia?

ASIC processes standard Pty Ltd registrations in 1-3 business days. ABN is typically issued same day. The full process from initial consultation to operational entity (including GST, TFN, resident director, registered office, and bank account facilitation) takes 2-4 weeks. We offer an expedited 5-business-day service for urgent timelines.

What is the corporate tax rate in Australia?

25% for base rate entities (aggregated turnover under $50M AUD) and 30% for larger companies. Most US companies entering Australia qualify for the 25% rate. Under the US-Australia DTA, dividends repatriated to a US parent holding 10%+ of voting stock are subject to only 5% withholding tax, and the US parent can claim foreign tax credits for both corporate tax and withholding tax paid.

Can I pay Australian employees from a US bank account?

No. If someone is performing employee work in Australia, you must either employ them through an Australian entity (with local payroll, super, PAYG withholding) or use an Employer of Record. Paying Australian workers as “contractors” from a US account when they are performing employee work is sham contracting, and the ATO and Fair Work Commission actively pursue these arrangements. Penalties reach $19,800 per contravention for individuals and $99,000 for companies. See our sham contracting penalties guide.

Do I need a physical office in Australia?

No. You need a registered office address (a physical Australian address for ASIC records), but there is no requirement to lease commercial space. Many US companies start with a registered office + virtual office and only lease physical premises once their team grows. Your employees can work remotely, from co-working spaces, or from client sites.

What is the difference between an ACN and an ARBN?

An ACN (Australian Company Number) is issued to companies incorporated in Australia, like a Pty Ltd subsidiary. An ARBN (Australian Registered Body Number) is issued to foreign companies registering a branch. The key difference: an ACN entity is a separate legal entity with its own rights and liabilities. An ARBN is your US parent company authorized to operate in Australia, with the US parent retaining full liability. For most US companies, a Pty Ltd (ACN) is the better choice. See our branch vs subsidiary comparison.

Can my US employees work remotely from Australia?

Short business visits (conferences, client meetings, training) are fine on a subclass 600 Business Visitor visa. But if a US employee works productively from Australia beyond 183 days in a 12-month period, you may trigger Australian income tax obligations, create a permanent establishment, and face payroll tax and superannuation requirements. For employees working from Australia regularly, establish an Australian entity and employ them locally, or use an EoR arrangement.
