If you take one thing from this page: a Caribbean passport is not a tax plan. It's the single most oversold idea in the category, often by people earning commission on the sale. Tax follows where you live, and CBI doesn't require you to live anywhere — so on its own it moves nothing.
Tax follows residence, not citizenship
Your tax residence is determined by where you actually live (typically 183+ days or your centre of vital interests), not by which passport you carry. Because Caribbean CBI imposes no residence requirement, getting the passport doesn't change where you're tax resident, and therefore doesn't change what you owe. To benefit from an island's tax regime you would have to genuinely relocate there.
What the islands actually offer — to residents
| Tax | Caribbean islands (for residents) | Applies to passport holders abroad? |
|---|---|---|
| Foreign income tax | Generally none for non-residents | No benefit unless you move there |
| Capital-gains tax | None | Benefit only on relocation |
| Wealth / inheritance tax | None | Benefit only on relocation |
| Your home-country tax | Unchanged by the passport | You still owe it where you live |
The islands do have genuinely light tax regimes — generally no tax on non-residents' foreign income, and no wealth, capital-gains or inheritance tax. But every one of these is a benefit of becoming resident, not of holding the passport. A holder who keeps living in a high-tax country gets none of them.
When the islands' tax regime actually helps
The tax advantages switch on only if you move to the island and become tax resident there, ceasing residence in your home country. That's a real lifestyle decision, not a paperwork step, and most CBI buyers never make it — they want mobility and a backup passport, not relocation to a small island. If low tax is genuinely the goal, a residence programme you actually use does more than a passport you don't live behind.
CRS: the passport does not hide you
Under the OECD Common Reporting Standard, banks identify and report account holders to their country of tax residence, based on where they live, not on which passport they present. A Caribbean passport doesn't change your reportable residence, and using a CBI passport to misstate your tax residency to a bank is fraud, not planning. The passport is a travel and backup document, not a confidentiality tool.
US persons: nothing changes
For US citizens and green-card holders, a Caribbean passport has no tax effect at all: the US taxes its persons on worldwide income wherever they live and whatever else they hold. CBI can still be a useful mobility and contingency tool for Americans, but it is emphatically not a way to reduce US tax, and short of formal expatriation (with its own exit-tax rules) nothing about a second passport touches the US obligation.
Buying Caribbean CBI as a tax strategy. The passport doesn't change where you're tax resident, so it doesn't change what you owe — the islands' tax perks require genuinely moving there, which most buyers don't. Under CRS your banks still report to where you live, and for US persons the IRS follows worldwide income regardless. Treat any pitch that frames a Caribbean passport as a tax cut as a red flag.
