Tax Haven

What it is

There is no universally accepted legal definition of a tax haven. The OECD historically used four indicative criteria: no or nominal tax on relevant income, lack of effective exchange of information, lack of transparency, and absence of substantial activities requirement. The European Union maintains a list of non-cooperative jurisdictions (the EU blacklist), and the FATF and OECD Forum on Harmful Tax Practices apply their own criteria. Common labels include the Cayman Islands, BVI, Bermuda, Bahamas, Panama, and parts of the Channel Islands.

Why the label is contentious

Many jurisdictions historically labelled as tax havens have introduced economic substance laws (Cayman, BVI, Bermuda, Jersey), public beneficial-ownership registers, and OECD-aligned exchange of information. Several have also signed the Multilateral Convention on Mutual Administrative Assistance in Tax Matters and CRS. As a result, the label is now more political than technical.

Why founders care

Using a low-tax jurisdiction is not illegal, but reputational, banking, treaty-access, and Pillar Two consequences can outweigh the tax savings. Many banks and payment providers de-risk against blacklisted jurisdictions. Choosing a credible low-tax jurisdiction (Singapore, Ireland, Netherlands) over an aggressive haven is usually a better operational choice.

You will see the tax-haven label come up when picking offshore holding jurisdictions, when banks and PSPs ask for substance evidence, when investors run reputational diligence, and when EU counterparties screen suppliers against the EU non-cooperative list before contracting or making payments.
