In 2021, Mercurius Advisory Services was engaged by a fast-growing Australian e-commerce group to provide global compliance support. With operations spanning Australia, ASEAN, the UK, China, Hong Kong, and a U.S. holding entity, the client needed a reliable partner to manage cross-border filings, including Form 5471 for their U.S.-registered foreign entity.<\/span><\/p>\n We appointed a seasoned accountant to lead the engagement, supported by our international compliance team. The result was timely, accurate submissions across jurisdictions, streamlined reporting, and ongoing peace of mind for the client\u2019s leadership team.<\/span><\/p>\n Founded in 2014, the client has established a broad network of 17 subsidiaries, 13 in Australia (of which 3 are currently inactive), and others based in China, the UK, Hong Kong, and the USA. The holding company operates as a strategic parent entity, supporting subsidiaries that deliver affordable E-commerce solutions, technology, and products to underserved small businesses in local markets.<\/span><\/p>\n The company\u2019s mission is to empower small enterprises by providing them with access to tools and services typically unavailable through traditional channels. While the U.S. entity remains non-operational, maintaining accurate records and making compliant disclosures (particularly Form 5471 with the IRS) is crucial for ensuring transparency, investor confidence, and facilitating expansion plans into Europe and the Americas.<\/span><\/p>\n The client needed a partner to:<\/span><\/p>\n \u2022 Prepare and file Form 5471 for the U.S. holding company\u00a0 Mercurius provided a dedicated compliance specialist, supported by in-house tax experts and a global network of advisors.
