Senior Tax Manager

Our APAC Tax team works closely with our Trading, Technology, Finance, Strategy and Legal teams to manage the tax position of IMC's business activities across the Asia-Pacific region. As a Senior Tax Manager at IMC, you will be the go-to tax advisor for the business, focusing primarily on the tax implications of new trading strategies, products, markets and structures. The role combines a strong advisory focus with hands-on ownership of tax compliance and reporting for our APAC entities. Reporting to our Head of Tax, APAC, you will also work with our global tax colleagues across the group on cross-border and group-wide matters.

Your Core Responsibilities:

• Partnering with Trading and Technology to advise on the tax implications of new trading strategies, financial instruments, venues and markets across APAC.
• Analysing trading-related direct and indirect taxes, including dividend withholding tax, stamp duties, financial transaction taxes and treaty positions.
• Advising on entity structuring, new market entry, licensing, restructurings, and strategic investments or acquisitions.
• Managing the APAC transfer pricing policy and intercompany arrangements, and assessing permanent establishment risk.
• Assessing the impact of tax law changes across APAC and translating them into clear recommendations for the business.
• Supporting with tax authority engagement in the APAC region, including ATO reviews, audits, private rulings and information requests.
• Working with external advisors on complex technical matters.
• Building practical tax guidance and training for traders, engineers and senior management.
• Hands-on management of tax compliance obligations, working with Finance and external providers. This includes Australian corporate tax compliance (income tax, withholding tax, GST and FBT) and other APAC jurisdictions, particularly Hong Kong.
• Reviewing tax provisions and tax notes in statutory financial statements.
• Supporting transfer pricing documentation, Country-by-Country Reporting, Pillar Two, FATCA and CRS obligations with the global Tax team.
• Maintaining the tax risk control framework and driving automation of tax processes through data and AI tools.
• Involvement with APAC tax incentive and R&D applications.

Your Skills and Experience:

• 8+ years of tax experience, with a strong advisory focus, gained at a Big 4, top-tier law or advisory firm and/or in-house at a bank, trading firm, asset manager or other financial institution.
• CA, CPA or qualified lawyer; a Master of Taxation or equivalent postgraduate tax qualification is highly regarded.
• Significant experience in tax structuring and transaction advisory, ideally in financial services.
• Strong international tax and transfer pricing knowledge, including permanent establishment and treaty matters.
• Solid grounding in Australian corporate tax compliance; experience with Hong Kong tax is highly regarded, and exposure to other APAC regimes is a plus.
• Working knowledge of tax provisioning and tax accounting.
• Ability to turn complex tax analysis into clear, practical advice for traders, engineers and senior management.
• A curious, commercial and automation-minded approach.
• Strong ownership and comfort working in a fast-paced, flat organisation.
