What Do Offshore Tax Advisors Do?
Offshore tax advisors provide cross-border tax advisory services relating to international structures, offshore jurisdictions and the tax obligations of individuals and entities operating across multiple jurisdictions. Their work typically spans international tax structuring, FATCA and CRS compliance, transfer pricing, tax treaty analysis, economic substance advisory and the reporting obligations arising in clients' home jurisdictions.
Offshore tax advisory is distinct from domestic tax compliance. The focus is on the interaction between offshore structures — companies, trusts, funds and foundations — and the tax rules of multiple jurisdictions simultaneously. The international tax landscape has changed significantly since 2010, driven by the OECD's Base Erosion and Profit Shifting project, the introduction of CRS automatic exchange of information, expanded FATCA obligations and the implementation of economic substance legislation across most offshore jurisdictions.
Major international accounting and advisory firms — including Deloitte, EY, KPMG, PwC and BDO — all maintain offshore tax practices, alongside specialist boutique tax advisory firms in jurisdictions including Switzerland, Jersey, Guernsey, Luxembourg and Singapore. The appropriate advisor depends on the complexity of the structure, the jurisdictions involved and whether the matter is primarily a corporate or private client matter.

Home Jurisdiction Obligations
Offshore tax advisory does not replace the need for tax advice in your home jurisdiction. The tax treatment of offshore structures depends critically on the residence, domicile and nationality of the individuals and entities involved. Always obtain tax advice from a qualified advisor in your home jurisdiction before establishing or modifying any offshore structure.
CRS Automatic Exchange
Over 100 jurisdictions have committed to the OECD Common Reporting Standard, under which offshore financial account information is automatically exchanged between tax authorities annually. Trust, company and fund accounts in offshore jurisdictions are typically reportable under CRS. Structures established with an expectation of non-disclosure should be reviewed against current CRS obligations.
FATCA Obligations
US persons — including US citizens, green card holders and certain US-connected entities — are subject to FATCA reporting obligations regardless of where assets are held. Offshore financial institutions are required to identify and report US accounts to the IRS. US persons with offshore structures should ensure they are fully compliant with all applicable FATCA and IRS reporting requirements.
Economic Substance
Most offshore jurisdictions have introduced economic substance legislation requiring entities carrying on certain activities to demonstrate genuine local activity. Failure to meet substance requirements can result in financial penalties and automatic exchange of information with the jurisdiction of the ultimate beneficial owner. Tax advisors with offshore experience can assist with substance assessment and compliance.
BEPS and International Tax Reform
The OECD's Base Erosion and Profit Shifting project and subsequent Pillar Two global minimum tax framework are reshaping the international tax landscape. Structures that were established before these reforms may require review. The interaction between BEPS measures, domestic legislation and bilateral tax treaties is complex and evolving.

Frequently Asked Questions
What do offshore tax advisors do?
Offshore tax advisors provide cross-border tax advisory services relating to international structures and offshore jurisdictions. Their work covers international tax structuring, FATCA and CRS compliance, transfer pricing, economic substance advisory and the reporting obligations arising in clients' home jurisdictions. Major firms including Deloitte, EY, KPMG, PwC and BDO all maintain offshore tax practices alongside specialist boutique advisors in key jurisdictions.
What is the Common Reporting Standard?
The Common Reporting Standard (CRS) is an OECD framework for the automatic exchange of financial account information between tax authorities. Over 100 jurisdictions participate in CRS, meaning offshore financial account information — including accounts held through trusts, companies and other structures — is routinely shared with the tax authority of the account holder's jurisdiction of residence on an annual basis.
What is FATCA?
FATCA — the US Foreign Account Tax Compliance Act — requires foreign financial institutions to identify and report accounts held by US persons to the US Internal Revenue Service. Offshore structures involving US persons, US assets or US-connected entities are typically subject to FATCA reporting obligations. Most offshore jurisdictions have entered into intergovernmental agreements with the US to implement FATCA within their local regulatory framework.
Do I need an offshore tax advisor and a home jurisdiction advisor?
In most cases, yes. The tax treatment of an offshore structure depends on the interaction between the rules of the offshore jurisdiction and the rules of the home jurisdiction of the individuals and entities involved. An offshore tax advisor can advise on the structure from the perspective of the offshore jurisdiction, but advice from a qualified tax advisor in your home jurisdiction is also essential to understand the full tax position.
