Step 2 of 4 · The mapTwo places where tax work happens, team by team
Where open source already does tax work. And where it doesn't yet.
Below are two places where tax work happens: a company's tax department, drawn from public tax-governance disclosures, and a tax authority, drawn from the functions in the OECD's Tax Administration series. Every team shows the activities it owns and what is open for each. Pick a team to see its processes and its projects. Where there is a gap, the page says so.
The blueprint
Where tax work happens, team by team.
A company's tax department and a tax authority. Pick one, then pick a team. The people at the top of each chart are there by design: no agent selects a material tax position.
Board and CFO on top, a Head of Tax, 10 specialist teams, country teams and local Finance executing, and the functions Tax works with every week.
Govern and decide
Board / Supervisory BoardApproves the tax strategy and risk appetite. Annual review, event-driven escalation.
Audit / Audit & Risk CommitteeOversight and challenge: material risks, control deficiencies, significant disputes.
Chief Financial OfficerExecutive owner of tax strategy, risk and resources. Approves high-materiality positions.
Head of Tax / Group TaxEnd-to-end function: policy, priorities, people, budget, material technical decisions, authority relationships.Tax governance · Transformation & operating model · people only
Advise, challenge and execute: the specialist teams. Pick one.
