Extax Advisory is a specialist cross-border tax adviser network of independent senior licensed practitioners, with more than a decade of Big 4 experience across international tax, M&A tax, transfer pricing, private client and high-wealth advisory, indirect tax, and global mobility.

Built around a model that does not exist at scale in the market: senior, ex-Big 4 calibre tax expertise, delivered outside the infrastructure cost of a large firm, to clients who have global complexity but expect direct access to principal-level counsel.

Extax Advisory works with senior execs, senior in-house counsel, expats across 60+ countries, inbound high-wealth migrants and pre-arrival structuring clients, cross-border directors and executives, private family offices, and corporates with European, APAC, African, or Oceania region exposure.

A growing proportion of engagements are conducted alongside a curated network of senior ex-Big 4 professionals and current Big 4 practitioners who engage where geographic gaps exist in their existing practice coverage, or where capacity constraints arise on large or specialised mandates. The network operates on a referral and co-engagement basis — no upfront commitment is required to participate.
