What it means
The defining features are usually a nominal or zero corporate tax rate, minimal requirement for real activity, and historically limited exchange of information with other tax authorities. Add straightforward incorporation and a stable legal system, and the jurisdiction becomes attractive as a place to book profit that was earned somewhere else.
Nothing about incorporating there is illegal in itself. The mechanics typically involve moving the profit rather than the operations.
A group might place its brand or patents in a low-tax subsidiary and charge operating companies royalties for their use, shifting margin out of higher-tax countries. Similar effects come from intra-group lending, where interest deductions arise in a high-tax country and interest income lands in a low-tax one.
The rules have tightened substantially. Transfer pricing regimes require intra-group charges to reflect what independent parties would agree, controlled foreign company rules tax parent companies on passive profits parked abroad, and economic substance requirements demand real staff and decision-making in the jurisdiction.
A global minimum tax framework also tops up group tax to a floor rate regardless of where profit is booked. Reputational risk now sits alongside legal risk.
Investors, customers and journalists treat haven structures as a signal worth investigating, and a structure that is perfectly legal can still damage a brand or complicate a public listing. Boards increasingly ask whether a structure could be explained comfortably in public before approving it.
There are also entirely mainstream uses that the label obscures. Investment funds are often domiciled in low-tax jurisdictions so that investors from many countries are taxed once in their home country rather than twice, which is about avoiding double taxation rather than escaping tax.
Understanding the purpose of a structure matters more than reacting to the jurisdiction's name.
In practice
Real-world examples.
Example
A consumer brand holds its trademarks in a low-tax territory and charges its European operating companies a 5% royalty on sales. Tax authorities in two of those countries open transfer pricing enquiries arguing the rate exceeds what an unrelated licensee would pay.
Example
A private equity fund is domiciled in a zero-tax island so that its investors, spread across a dozen countries, are each taxed once at home. The structure is disclosed to every investor and to each tax authority under information exchange rules.
Example
A mid-sized software company considers routing licence income through a low-tax subsidiary but abandons the plan after calculating that substance requirements would cost more than the tax saved and that its enterprise customers ask about tax conduct in procurement questionnaires.
Think of it
“Tax haven is a low-tax place to park money-jurisdictions used to avoid taxes.
Formula
Calculation
Formula: Annual tax saving = Profit shifted x (Home tax rate - Haven tax rate), less the running cost of the structure.
Worked example: a group relocates intellectual property generating $10,000,000 of annual profit from a country taxing at 25% to a jurisdiction taxing at 2%. Tax at home would be $10,000,000 x 25% = $2,500,000, while tax in the low-tax jurisdiction is $10,000,000 x 2% = $200,000, a gross saving of $2,300,000.
Running the structure properly costs $600,000 a year in local staff, offices, directors and advisory fees, so the net saving is $2,300,000 - $600,000 = $1,700,000. If a global minimum tax of 15% then applies, the top-up is $10,000,000 x (15% - 2%) = $1,300,000, cutting the net benefit to $1,700,000 - $1,300,000 = $400,000.Case study
Seen in the real world.
Larkmoor Devices is a fictional electronics group presented here as an illustrative example. Its advisers proposed moving patent ownership to a low-tax jurisdiction, projecting a $1,900,000 annual saving on $8,000,000 of licence profit. The board approved the plan in principle.
The finance director then modelled it more fully. Meeting substance requirements meant hiring four staff and taking real office space locally at $520,000 a year, an anticipated minimum tax top-up removed a further $1,040,000, and the group's largest customer had begun asking suppliers to confirm they did not book profit in jurisdictions without operations. The projected benefit fell to roughly $340,000 against a first-year implementation cost of $900,000.
Larkmoor kept the patents where its engineers actually worked and instead claimed a domestic patent incentive worth about $600,000 a year with no reputational exposure. The fictional board minute recorded that the simplest defensible answer had turned out to be the most profitable one.
Watch out
Common mistakes.
- Assuming any use of a low-tax jurisdiction is illegal, when the legality depends entirely on disclosure, substance and whether the arrangements match economic reality.
- Modelling only the headline rate difference and ignoring substance costs, minimum tax top-ups and professional fees, which often consume most of the saving.
- Treating secrecy as durable, when automatic exchange of information means account and ownership data now flows between authorities as a matter of routine.
Questions
People also ask.
Is there an official list of tax havens?
Several bodies publish lists of non-cooperative jurisdictions, but they differ and change, so no single definitive list exists.
Does a global minimum tax end the practice?
It reduces the benefit of very low rates by topping group tax up to a floor, but it does not remove every reason to use these jurisdictions, particularly for investment funds.
Will using one damage our reputation?
Possibly, since customers, investors and journalists increasingly treat these structures as a governance signal, so test whether you could explain it publicly before proceeding.
