Service providers for foreign-owned Australian subsidiaries: who does what

Foreign-owned Australian subsidiaries need a specific bundle of compliance services that no single provider category covers cleanly. The major players in 2026 are CoSec Partners (working alongside its sister firm ABN Australia for business establishment and accounting), Acclime (regional Asian network with broader bundles), Beachhead Advantage and Lansdowne Financial (Australian specialists offering similar bundles to CoSec), and the Big 4 international tax practices. Each suits a different size and complexity of subsidiary.

The compliance stack a foreign-owned subsidiary actually needs comprises nine main items: ASIC company registration, ABN/TFN/GST, resident director under section 201A of the Corporations Act, registered office address, public officer appointment under the Income Tax Assessment Act, ongoing ASIC compliance, payroll setup if local staff will be engaged, accounting and tax compliance, and transfer pricing advice where the subsidiary trades with the parent group. Few providers do all of this in-house, so the question is which combination of providers covers the bundle.

CoSec Partners covers the corporate secretarial side: ASIC registration, resident director, registered office, public officer, ongoing ASIC compliance, share register management, and director ID coordination including the paper-based application process required for non-resident directors. Our sister firm ABN Australia covers business establishment and accounting, including ABN, TFN and GST registration, ongoing ATO compliance, and accounting work. Together they cover the full Australian execution requirement.

Acclime is a regional player with offices across Asia-Pacific. It suits foreign groups already in Acclime’s network in Singapore, Hong Kong, or Mainland China, where having a single provider across multiple APAC jurisdictions is operationally valuable. Pricing may be higher where the regional network is part of what is being purchased. Best for groups that need joined-up reporting across multiple Asian jurisdictions.

Beachhead Advantage and Lansdowne Financial are Australian specialists in the same niche. Both offer resident director and registered office services; check each provider’s current scope directly. Either may be a good fit for groups that prefer a domestic-only provider and want a single Australian relationship.

Big 4 firms (PwC, KPMG, Deloitte, EY) suit larger groups with substantial Australian footprint, typically $50M+ revenue, complex transfer pricing, M&A activity, or specific industry expertise needs. Pricing is materially higher and the engagement structure is partner-led. The Big 4 fit is mainly three types of group: major listed inbound investments, complex private equity backed groups, and structurally complex multinationals.

For most small-to-mid foreign-owned subsidiaries (under $50M revenue typical), CoSec Partners + ABN Australia is the appropriate fit. We work directly with the parent group’s home-jurisdiction tax advisers, handle the Australian execution, and avoid the Big 4 cost premium. The /foreign-subsidiary-compliance page describes the bundled engagement specifically. For groups with broader APAC requirements, Acclime is a strong choice. For very large or complex groups, Big 4 is the right answer.

Practical decision questions: Does the parent group already have a tax adviser in their home country? (If yes, you only need Australian execution.) Does the group have operations in multiple Asian jurisdictions? (If yes, regional providers may be better.) Is the Australian footprint expected to grow into a substantial business? (If yes, the cheaper option may be a false economy if you outgrow it within two years.) These three questions usually decide the right provider category.
