Australia-US Tax Treaty for Wyoming LLC Owners (2026)

Australia-US Tax Treaty for Wyoming LLC Owners

Australia-US tax treaty is active. US-source dividends drop to 5-15% with W-8BEN-E. Article 7 protects business profits. For SaaS, agency, content creator businesses based in Australia, US federal tax exposure is usually zero. ATO treatment of US LLCs varies (partnership, company, or transparent), so consult an Australian CPA to align structures.

Article 11 (Interest): 0-10% on portfolio interest.
Article 12 (Royalties): 5% under the treaty.
Article 22 (Relief from Double Taxation): FTC mechanism in both directions.

How the ATO treats US LLCs

ATO treatment of US LLCs depends on facts and elections. The LLC may be classified as a foreign hybrid limited partnership (transparent under Australian rules), a foreign company (opaque), or as transparent only on specific elections. Outcomes differ significantly between these treatments for Australian tax.

Practical approach: most Australian founders we serve work with an Australian CPA familiar with Subdivision 830 of the ITAA 1997 (foreign hybrid rules) to ensure the LLC is treated as a foreign hybrid limited partnership, which gives transparent treatment aligned with US treatment.
