Tax Manager - Asia

Octopus Energy Generation is a specialist energy investment manager, overseeing more than £7 billion of assets under management. Our mission is to accelerate the transition to a net zero energy system by investing in clean energy infrastructure and energy transition businesses.

Our strategies span renewable generation, distributed energy, and broader energy transition platforms across multiple technologies and jurisdictions. As our portfolio of development-stage and growth strategies continues to expand, we are strengthening our in‑house tax capability to provide proactive, commercially focused support across fund structures and underlying investments.

We are seeking a Tax Manager to join the OEGen Tax Team, reporting directly to the Head of Tax. This role will take primary responsibility for a defined bucket of OEGen’s funds comprising a group of funds investing in energy transition technologies and early‑stage businesses, adopting a venture capital / private equity‑style investment strategy and a fund focused on the Asia‑Pacific region, investing across a broad range of renewable energy assets.

You will act as the central tax lead for these funds, working closely with investment teams, portfolio companies, finance teams, and external advisors across multiple jurisdictions. The role combines fund‑level tax strategy and governance with hands‑on oversight of compliance, reporting, risk management, and transaction execution.

This position offers both breadth and technical complexity: exposure to early‑stage equity investments, minority growth stakes, cross‑border holding structures, and infrastructure assets across diverse Asia‑Pacific jurisdictions.

• Take ownership of tax matters relating to a defined portfolio of OEGen’s energy transition technology funds and Asia‑Pacific renewable energy fund.
• Support holding structures, co‑invest arrangements, and cross‑border investment planning in collaboration with the investment team and external advisors.
• Ensure tax considerations are appropriately reflected in documentation, SPV structuring, financing arrangements, and exit planning.
• Provide tax input on matters specific to early‑stage and growth equity investing.

• Oversee the delivery of tax compliance obligations (e.g. corporate income tax, VAT, withholding tax, local filings) across fund and holding structures in multiple jurisdictions, including APAC territories.
• Coordinate and manage local advisors to ensure accurate, timely submissions and full regulatory compliance.
• Maintain oversight of compliance calendars and reporting trackers at both fund and asset‑holding levels.
• Monitor evolving tax legislation across relevant jurisdictions, particularly in emerging energy‑transition markets.

• Support fund & platform finance teams with tax provisioning and financial statement disclosures.
• Review tax‑related journal entries and ensure appropriate treatment of current and deferred taxes.
• Oversee the integrity and documentation of tax positions reflected in audited financial statements.
• Assist with investor reporting and tax disclosures.

• Maintain robust tax governance frameworks across the relevant funds and structures, reflecting the risk profile of both VC‑style investments and APAC infrastructure assets.
• Oversee tax audits or enquiries by local authorities, managing advisors and internal stakeholders.
• Identify, assess, and elevate material tax risks in a commercially informed and pragmatic manner.
• Ensure alignment with OEGen’s broader tax strategy, risk appetite, and governance standards.

• Lead tax work streams on acquisitions, disposals, follow‑on investments, restructurings, refinancings, secondary transactions, and group reorganisations within the relevant funds.
• Support due diligence processes for early‑stage technology investments and infrastructure asset acquisitions across APAC.
• Review legal and commercial documentation with a tax lens, identifying structuring implications and risk areas.
• Coordinate external advisors and internal stakeholders to ensure seamless execution…
