Australian Branch Tax Guide: How Foreign Branches Are Taxed

A registered Australian branch is the same legal entity as its foreign parent. That single fact drives everything about how it is taxed: the foreign company itself pays Australian tax on the profits its branch earns here, lodges its own Australian tax return under its own TFN, and can pull profits home without a cent of dividend withholding tax. As at June 2026, Australia has no branch profits tax and no withholding tax on branch remittances, which makes the branch one of the cleanest repatriation structures available to foreign companies.

This guide explains how a registered branch (an ARBN holder under Part 5B.2 of the Corporations Act 2001) is actually taxed and exactly what it must lodge with the ATO and ASIC each year. If you are still weighing up whether to register a branch or incorporate a subsidiary, start with our branch vs subsidiary comparison for the full decision framework. This article assumes the branch decision is made, or close to it, and gets into the tax mechanics.

How Australian Branch Profits Are Taxed

The Tax Rate: 30% for Most, 25% for a Few

A foreign company is taxed in Australia only on its Australian-sourced income, which for a branch generally means the business profits attributable to its Australian operations. The rate is the standard Australian corporate rate: 30%, or 25% if the company qualifies as a base rate entity (source: ATO, company tax rates).

Here is the part most overseas advisers get wrong: there is no residency condition in the base rate entity test. A non-resident company can access the 25% rate. The two tests are aggregated turnover under AU$50 million and no more than 80% of assessable income being passive income (interest, rent, royalties, dividends, net capital gains). The catch is the word “aggregated”: the turnover test counts the worldwide turnover of the foreign company and every entity connected with or affiliated with it. A branch of a multinational group doing AU$200 million globally pays 30% even if the Australian operation bills AU$2 million. A genuinely small foreign company whose entire global group turns over less than AU$50 million, with active trading income, pays 25% on its Australian branch profits.

Which Profits Australia Gets to Tax

Because the branch is not a separate entity, Australia cannot simply tax “the branch’s accounts”. It taxes the profits attributable to the Australian operations. Where the parent is resident in one of Australia’s 45-plus treaty countries, the business profits article of the relevant double tax agreement (usually Article 7) governs the attribution: the branch is treated, broadly, as if it were a distinct and separate enterprise dealing at arm’s length with its head office, and only the profits that hypothetical enterprise would have earned are taxable in Australia. Domestically, Subdivision 815-C of the ITAA 1997 applies arm’s length principles to the same exercise, although Australia has not fully adopted the OECD’s authorised approach, which matters for internal dealings (more on that below).

In practice, attribution means keeping branch accounts that record the Australian revenue, the direct Australian costs, and a defensible allocation of head office costs that genuinely relate to the Australian operations. The ATO expects to see the methodology documented, not reverse-engineered at return time.

One boundary note: this guide is about companies that have registered with ASIC and hold an ARBN. If you are operating in Australia without any registration and the real question is whether Australia can tax you at all, that is a threshold issue, and our permanent establishment guide covers it in detail. Registering a branch does not itself create the tax liability; carrying on business through an Australian PE does. But almost every registered branch has one.

The Repatriation Advantage: No Dividend Withholding Tax

Australia imposes withholding tax on dividends, interest and royalties paid to non-residents. A branch remittance is none of those things. When the branch transfers its after-tax profits to head office, no dividend is being paid, because a company cannot pay a dividend to itself. And unlike the United States, Australia imposes no branch profits tax to plug that gap. The after-tax profit simply moves, whenever the company wants, with no Australian tax on the transfer and no dividend paperwork.

Compare that with a subsidiary. An Australian subsidiary repatriates by paying dividends, and the outcome depends on its franking position. Fully franked dividends (paid from profits that have borne Australian company tax) are exempt from withholding tax. Unfranked dividends are hit with 30% withholding, reduced to 5-15% under most treaties, and Australia has no treaty with Hong Kong at all. Our profit repatriation guide works through the full menu of dividends, interest, royalties and management fees.

Worked Example: AU$1,000,000 of Australian Profit

A Hong Kong parent company earns AU$1,000,000 of pre-tax profit from its Australian operations and wants the cash back in Hong Kong. The group is over AU$50 million in turnover, so the 30% rate applies either way.

To be fair to the subsidiary: if that dividend were fully franked, the withholding tax would also be AU$0. The branch advantage is not that subsidiaries always pay withholding tax; it is certainty and timing. A branch never needs to track franking credits, never produces an unfranked component through timing differences, and never strands cash waiting for franking capacity. Subsidiaries claiming the R&D tax offset, carrying forward losses, or distributing faster than they generate franking credits routinely end up with unfranked components, and that is where the 30% (or treaty 5-15%) bites. A branch is structurally incapable of having that problem.

What an Australian Branch Must Lodge

The lodgment burden sits on the foreign company itself, on both the tax and the corporate side. This is the branch-specific list; for the obligations that apply to every foreign company operating here, registered or not, see our tax compliance guide for foreign companies in Australia.

ATO Lodgments

• Company tax return. The foreign company applies for its own Australian TFN and lodges a company income tax return reporting the branch profits. Companies whose home financial year is not 30 June can apply for a substituted accounting period (a 31 December balancer is common), which keeps the Australian return aligned with group reporting. Using a registered tax agent typically extends the lodgment deadline well beyond the standard dates.
• Business Activity Statements. GST registration is required once GST turnover from sales connected with Australia reaches AU$75,000, and the registration belongs to the foreign company itself, not to the branch (source: ATO, GST for non-resident businesses). Once registered, BAS lodgment is usually quarterly.
• PAYG withholding, superannuation and payroll obligations. If the branch employs staff in Australia, the foreign company must register for PAYG withholding, report through Single Touch Payroll, pay 12% superannuation, and deal with state payroll tax once it crosses the relevant state threshold. These obligations attach to the employer regardless of where it is incorporated.
• International Dealings Schedule (IDS). If related-party international dealings, including dealings between the branch and its own head office, exceed AU$2 million for the year, the IDS must be lodged with the tax return.
• Transfer pricing documentation. Contemporaneous documentation supporting the attribution of profits and any head office cost allocations, prepared before the return is lodged, is what earns a reasonably arguable position if the ATO reviews the numbers.

Late lodgment is not cheap. Failure-to-lodge penalties accrue at one penalty unit (AU$330 in 2025-26) per 28 days, capped at five units for small entities, but the multiplier for significant global entities (groups with AU$1 billion-plus global income) is 500 times, taking a single late return to a maximum of AU$825,000.

ASIC Lodgments

The corporate side runs in parallel (source: ASIC, obligations of foreign companies):

• Financial statements (Form 405). A registered foreign company must lodge its financial statements (balance sheet, profit and loss, cash flow statement, prepared per the law of its place of origin) at least once each calendar year, with no more than 15 months between lodgments, verified by Form 405. These are the parent company’s accounts, and they go on the public record, a disclosure point that surprises some private groups.
• Annual return (Form 406). Foreign companies that qualify for relief from financial reporting under ASIC Instrument 2017/204 lodge a Form 406 annual return instead, within one month after the AGM. The lodgment fee for the annual filing is AU$1,583 from 1 July 2026 (AU$1,521 until 30 June 2026).
• Local agent. A registered foreign company must have a local agent ordinarily resident in Australia at all times. The agent is answerable for everything the company must do under the Corporations Act and is personally liable for penalties (section 601CG), which is why professional agents charge for the risk, not the paperwork.
• Change notifications. Changes to directors, constitution, registered office or local agent must be notified to ASIC within prescribed windows, and the company’s name and ARBN must appear on all public documents.

For completeness on setup costs: the original registration on Form 402 carries an ASIC fee of AU$636 from 1 July 2026 (AU$611 until 30 June 2026), and full-service branch registration starts at AU$1,500.

Thin Capitalisation and Dealings with Head Office

Two sets of rules police the boundary between the branch and the rest of the company.

Thin capitalisation. A foreign company claiming debt deductions against Australian assessable income is an inward investor under Division 820. Since 1 July 2023 the default test is earnings-based: net debt deductions are capped at 30% of tax EBITDA under the fixed ratio test, with the group ratio test and third party debt test as elective alternatives (source: ATO, fixed ratio test). Denied amounts under the fixed ratio test can be carried forward for up to 15 years. A de minimis exemption applies where total debt deductions, combined with associates, are AU$2 million or less for the year, which keeps most small branches out of the regime entirely.

Head office dealings. Transfer pricing under Subdivision 815-B applies to the branch’s actual transactions with related entities in the group. But dealings with the company’s own head office are legally not transactions at all, and Australia does not fully recognise internal dealings the way the OECD’s functionally separate entity approach would. The practical consequences: the branch cannot deduct notional interest on funds “borrowed” from head office (banks are the main exception), cannot deduct internal royalties for using the company’s own IP, and head office charges are deductible only as allocations of actual third-party costs that relate to the Australian operations, without an internal markup. Groups that model branch profits assuming subsidiary-style management fee and royalty deductions overstate the deductions and understate the Australian tax.

Branch vs Subsidiary: The Tax Differences at a Glance

The table covers tax mechanics only. Liability exposure, contracting credibility and governance often decide the structure question in the other direction, and the full comparison linked above weighs all of it. For the other side of this table in depth, see our guide to the taxation of foreign subsidiaries in Australia.

When a Branch Makes Tax Sense

Pulling the threads together, the branch structure tends to win on tax where:

• Early losses are expected. Australian start-up losses sit in the foreign company and, depending on home jurisdiction rules, may relieve head office profits years before a subsidiary’s trapped losses would do anyone any good.
• Profits will be repatriated quickly and regularly. No franking management, no withholding tax exposure, no dividend mechanics.
• The parent is in a non-treaty jurisdiction. Hong Kong parents in particular avoid the 30% unfranked dividend withholding risk entirely.
• The operation is project-based or time-limited. Construction contracts, resource projects and fixed-term engagements wind up cleanly, with no company to deregister and no exit dividend.
• Home country tax treatment of branch income is favourable, for example where a participation or branch exemption means Australian-taxed profits arrive home without a top-up.

It tends to lose where the R&D Tax Incentive matters, where the parent wants its accounts off the Australian public record, or where Australian losses are unlikely but Australian liability exposure is.

Frequently Asked Questions

What tax rate does an Australian branch of a foreign company pay?

30% on profits attributable to the Australian operations, or 25% if the foreign company is a base rate entity. The base rate entity test has no residency condition, but its AU$50 million aggregated turnover threshold counts the worldwide turnover of the entire connected group, so most multinational branches pay 30%.

Does Australia have a branch profits tax?

No. Australia taxes branch profits at the corporate rate and imposes no further tax when those after-tax profits are remitted to head office. A branch remittance is not a dividend, so dividend withholding tax cannot apply, and no separate branch profits tax exists, as at June 2026.

Does a registered branch lodge an Australian tax return?

Yes. The foreign company itself obtains an Australian TFN and lodges a company income tax return reporting the branch’s attributable profits each year. A substituted accounting period can align the Australian return with the parent’s home financial year, and an International Dealings Schedule is required if related-party dealings exceed AU$2 million.

Can Australian branch losses be offset against other profits?

Branch losses belong to the foreign company. In Australia they carry forward against future Australian profits, subject to the continuity of ownership or business continuity tests. They cannot be transferred into an Australian consolidated group, but many home jurisdictions allow current-year branch losses to offset head office profits, which is a key reason loss-making market entries often start as branches.

Does the foreign company need to register for GST?

Yes, once its GST turnover from sales connected with Australia reaches AU$75,000. The registration is in the name of the foreign company, using its own ABN. Once registered, the company lodges Business Activity Statements, usually quarterly, covering the branch’s Australian sales and input tax credits.

What does a branch have to file with ASIC each year?

The parent company’s financial statements verified by Form 405 at least once each calendar year (no more than 15 months apart), or a Form 406 annual return if ASIC reporting relief applies. The lodgment fee is AU$1,583 from 1 July 2026 (AU$1,521 until 30 June 2026), and the company must maintain a local agent in Australia at all times.
