What we do.
How we do it differently.

Multi-Jurisdictional Tax Advisory through WONE Global is different in one fundamental way: every engagement is coordinated across jurisdictions by one team, to one standard, with one contact — regardless of how many countries are involved.

"The question is not whether your advisers are excellent in their own market. The question is whether they can deliver the same quality across every market where you need them."

WONE's tax practice operates through the WONE OS deal flow engine — meaning client briefs are matched to the best-qualified senior partner in each jurisdiction, assembled as a coordinated team, and delivered under one unified quality standard.

There are no referral arrangements between unconnected firms. No hope that someone in another country will pick up the phone. Every tax engagement at WONE is delivered by a team assembled specifically for that brief — senior partners, the right jurisdictions, the right expertise — coordinated from day one.

What we cover
in tax.

Eight service areas — all delivered with senior partner expertise, all coordinated across jurisdictions, all under the WONE quality standard.

01
Multi-Jurisdictional Tax Strategy
Designing tax-efficient structures for businesses operating across multiple countries — balancing group-level optimisation with local compliance reality and regulatory risk.
02
Transfer Pricing
Transfer pricing documentation, policy design, benchmarking analysis, and dispute management — across the jurisdictions where your group operates and where tax authorities are most active.
03
M&A Tax Structuring
Tax due diligence, acquisition structuring, and post-acquisition integration planning across cross-border transactions — coordinated with the legal and advisory teams involved.
04
Corporate Income Tax Compliance
Multi-jurisdictional corporate tax return preparation, compliance management, and tax authority liaison — to one standard, across every country in your group structure.
05
VAT / GST Cross-Border
Managing indirect tax compliance across multiple VAT and GST regimes — registration, filing, recovery, and managing cross-border supply chain tax exposure.
06
Wealth & Private Client Tax
International tax planning for high-net-worth individuals, family offices, and entrepreneurs — covering domicile, residence, inheritance, and the cross-border implications of wealth held across jurisdictions.
07
Digital Economy Taxation
Navigating the rapidly changing tax landscape for digital businesses — including digital services taxes, permanent establishment risk, and OECD Pillar Two minimum tax implications.
08
Tax Controversy & Dispute
Representing clients in tax authority disputes, audits, and appeals across multiple jurisdictions — including mutual agreement procedures and international arbitration under tax treaties.
02
Who We Serve

The clients who
come to WONE for tax.

Four client groups with distinct tax needs — each served by a team assembled specifically for their situation, jurisdiction, and brief.

CFOs & Finance Directors
Group finance teams managing tax risk and compliance across multiple jurisdictions — where WONE provides the coordinated external tax function that matches the complexity of the group.
Private Equity & Family Offices
Investors structuring cross-border portfolios and managing the tax consequences of international investment — from acquisition through exit and wealth distribution.
Founders & Entrepreneurs
Founders scaling internationally who need tax advice that addresses the actual structure they are building — not a template designed for a Fortune 500 company.
Multinationals
Established groups managing ongoing transfer pricing risk, multi-jurisdictional compliance, and the increasing scrutiny of international tax structures from tax authorities globally.
03
Sectors

Deep sector expertise
across every major industry.

WONE tax partners bring sector expertise alongside jurisdictional knowledge — meaning clients receive advice that understands the industry as well as the law, the tax regime, or the accounting standard.
