Senior Tax Analyst – Pillar II

This is a hybrid role with the flexibility to work both virtually and from our Krakow office as part of a global tax team.

Aon is in the business of better decisions

At Aon, we shape decisions for the better to protect and enrich the lives of people around the world. As an organization, we are united through trust as one inclusive, diverse team, and we are passionate about helping our colleagues and clients succeed.

You will be part of Aon’s global Pillar II team and will work closely with the Manager – Tax Reporting Pillar II based in Amsterdam, as well as regional tax and finance teams around the world.

What the day will look like

As a Senior Tax Analyst – Pillar II, you will support the implementation and ongoing compliance of the OECD/GloBE Pillar II rules across Aon’s global structure. Under the guidance of the Manager – Tax Reporting Pillar II, you will:

• Assist with the preparation of Pillar II calculations and related workpapers for jurisdictions within Aon’s global footprint.

• Support the gathering, validation, and analysis of financial and tax data required for Pillar II calculations and reporting.

• Help with the integration and maintenance of Pillar II data and processes in Aon’s tax systems and tools (e.g., Orbitax or similar).

• Assist in the preparation of quarterly Pillar II calculations for group and SEC reporting in close coordination with the tax accounting team.

• Support the monitoring of global and local Pillar II legislative developments and help translate them into practical data and process requirements.

• Prepare and maintain documentation to support Pillar II calculations, controls, and internal governance requirements.

• Provide support for internal and external audit requests related to Pillar II (including SOX-related documentation where applicable).

• Collaborate with tax managers across regions, local finance teams and external advisors in connection with Pillar II data requests, reviews, and compliance.

• Contribute to process improvements, standardization and automation initiatives within the Pillar II reporting and compliance framework.

• Gain hands-on experience with Pillar II data, calculations and reporting for a large multinational group.

• Work closely with the Manager – Tax Reporting Pillar II and a network of regional tax managers, local finance teams and external advisors.
