tax legal skills by jurisdiction

Tax work is defined by its convergence of moving parts: a single cross-border transaction can simultaneously engage domestic income tax codes, VAT or GST regimes, bilateral treaty networks, and OECD Pillar Two global minimum tax rules — often on an accelerated timeline. The tax legal skills assembled in the ThomasMore catalog are built for that layered complexity, covering corporate tax, indirect taxes, transfer pricing, withholding obligations, residency determinations, and revenue-authority controversy across a wide range of jurisdictions. Each capability is agent-ready, meaning it handles a discrete, repeatable task — mapping a permanent establishment risk, drafting a treaty position memo, or structuring a compliance checklist — and is accessible over MCP or as a direct download into your existing workflow.

Tax law rarely stays static: domestic codes are amended by budgets, OECD standards evolve, and administrations update guidance with little notice, so the open-source skills in this collection are maintained to reflect those shifts as they happen. Authors draw on jurisdiction-specific rules rather than generic approximations, which matters when the correct answer turns on a domestic anti-avoidance provision or a local filing formality that broader tools overlook. Whether you advise on group restructurings, advise individuals on cross-border residency, or represent clients in audit and dispute proceedings, the catalog's filter tools let you narrow by jurisdiction, author, or license to surface the skill your matter actually requires. Start with the jurisdiction most relevant to your current work and build from there.
