Territorial Tax, Explained

Under a territorial tax system a country taxes income arising inside its own borders and leaves foreign-source income outside the net. That is genuinely powerful for the right family: an entrepreneur earning abroad who actually relocates can end up with a local tax bill close to nothing, and none of the finality of surrendering a citizenship.

The catch is the definition. Every territorial system draws its own line around what counts as foreign-source, and the line rarely sits where a new resident assumes — work performed on the ground, income paid by a local entity, and in some systems anything routed through a local bank account can all land inside the net. Panama is the one most families meet first, and Costa Rica runs its own version; the systems look alike from a distance and differ sharply in the detail that decides your bill.

Most of the confusion here comes from treating four different things as one. A zero-tax jurisdiction levies no personal income tax on anyone — the Cayman Islands, The Bahamas, Bermuda, Anguilla and the British Virgin Islands — so there is no foreign-source question, because there is no income tax to ask it. A territorial jurisdiction taxes local income and exempts foreign income; Panama is the classic case, and what you do with the money afterwards is largely irrelevant. A residence-based jurisdiction taxes worldwide income once you are resident: Canada, the United Kingdom, most of Europe. And the United States taxes on citizenship, which is why half of this page exists.

The fourth is the one that trips people. A remittance-basis jurisdiction taxes foreign income when it is brought in, so the wire home becomes the taxable event. Barbados offers remittance-basis treatment to qualifying new residents; Malta and Ireland run non-dom remittance regimes; Britain’s ran from 1799 until it was abolished on 6 April 2025, which I covered in the non-dom abolition and the exodus that followed. Thailand restructured its rule on 1 January 2024 so that foreign income remitted by a tax resident is taxable at progressive rates reaching 35%, ending the old next-year deferral.

Families who confuse territorial with remittance structure their banking backwards. In a territorial system the account the money lands in is mostly beside the point. Under a remittance basis it is close to the only thing that matters.

Source is a legal test, not a description of where the money feels like it came from, and it is the most under-read part of any relocation plan. Four lines catch new residents more than the rest. Where the work is performed — a laptop in a rented apartment can source income locally even when every client is abroad, because the service was rendered inside the country. Who pays you — income paid by a locally incorporated company is local income in most systems, whatever the customer’s address. Where the asset sits — rent on a local house, gain on local land, interest on a local deposit are local by situs. And in some systems, how the money moves: the routing itself brings it into charge.

The most litigated sourcing rule an American will ever meet is not in Panama at all. It is Puerto Rico’s. Section 933 excludes Puerto Rico-source income from US federal tax for a bona fide resident, and Treasury’s regulations then treat gain on property owned before the move as non-Puerto-Rico-source if sold within ten years of arriving. The rate is not doing the work there; the sourcing rule is. Act 60 plans go wrong at exactly that line, and territorial systems go wrong at their own equivalents.

I have not yet seen a family lose money because they misread a headline rate. I have seen several misread a source rule.

Panama is the territorial base most of my clients meet first: fully dollarised, with two investor residency routes — the Qualified Investor Visa from US$300,000 in titled real estate, and the Friendly Nations Visa from US$200,000 in titled real estate or a fixed bank deposit. Income arising in Panama is taxed there; foreign-source income is generally left outside the net.

What catches people is that a residency card is not tax residency. Panama can issue the permit while your centre of life, and therefore your tax home, stays exactly where it was. Panamanian tax residency generally turns on more than 183 days in the country in a year alongside a genuine centre of life there, and the certificate that proves it is a separate application to the Dirección General de Ingresos, reviewed case by case, with waits practitioners routinely report at five months or more. Plan for it as its own project rather than a by-product of the visa.

Costa Rica leans territorial rather than being flatly so, and I use that word deliberately: local income is taxed, foreign-source income has generally sat outside the net, and the treatment of foreign passive income has faced periodic reform pressure. Three routes carry nearly every file — inversionista at US$150,000, rentista for portable income, pensionado for a lifetime pension. A plan should never be built on the word “generally”.

Barbados belongs in the comparison for the opposite reason: it is not territorial. Qualifying new residents can be taxed on a remittance basis, and the island trades on an extensive treaty network — including a comprehensive US income tax treaty, one of only three in the Caribbean alongside Jamaica and Trinidad & Tobago — rather than on a zero rate. Its Special Entry and Reside Permit opens at US$300,000 of Barbados property.

One thing territorial does not describe is the Caribbean citizenship islands. Of the five programs, only St. Kitts & Nevis and Antigua & Barbuda levy no personal income tax on residents; Dominica taxes residents at rates up to 35%, St. Lucia up to 30% and Grenada up to 28%. That gets settled on the side-by-side comparison, and the wider map on the residency by investment page.

Territoriality does not help a US citizen, and I would rather open a section with that than bury it. The United States taxes on citizenship: US citizens remain taxed by the United States on worldwide income regardless of a second citizenship, and none of the five Caribbean programs has a US income tax treaty. Panama’s territorial system describes Panama’s claim on your income. It says nothing about the IRS’s.

The relief that exists is narrower than people expect. The Foreign Earned Income Exclusion shelters US$132,900 for 2026, and only earned income qualifies — salary does; capital gains, dividends, interest and rent do not. A family living on a portfolio rather than a paycheque gets very little from it. A lightly taxed jurisdiction also generates few foreign tax credits to set against a US liability, so a low local rate can quietly leave an American no better off than a higher one would.

Two things genuinely move an American’s number. Puerto Rico’s Act 60 works inside the US system rather than around it. Renouncing US citizenship works outside it, and is the last step rather than the first — taken rarely, never before a second citizenship is settled, and only after reading when it actually makes sense. For non-American families, territoriality does real work — but only once the exit from the old system is complete, which is the harder half and the one I see planned last.

A tax residency you cannot evidence is one your old country will not accept. Under the Common Reporting Standard, financial accounts are reported to the jurisdiction where you claim tax residency, so a certificate with no days and no home behind it is an audit flag rather than a plan. Banks ask for a self-certification at onboarding and, increasingly, for something behind it.

That is why my team sequences the banking introductions ahead of the residency file rather than after it. An account opened in the jurisdiction you claim, in the year you claim it, with a lease and a utility bill behind it, is worth more in an argument than any certificate on its own. Where the design runs deeper — which entity holds what, where income lands, how it passes on — the mechanics sit with ownership structure and offshore banking, and I coordinate those alongside your own counsel rather than taking the mandate myself.

Four profiles, and I say so early rather than late. The family that wants the certificate and not the country: substance is the whole product, and without days and a home a territorial residency is a liability rather than an asset. The family whose income is anchored to one place — a US-listed salary, a UK rental portfolio, a Canadian professional practice — because anchored income stays sourced where it arises, and moving the person does not move it.

The family whose entire thesis is a zero rate: territorial is not zero, so go where there is one — the Cayman Islands at US$1.2M for the 25-year certificate, or The Bahamas from US$1,000,000 in real estate. When you see Panama or Costa Rica on a list of tax-free countries, close the tab; the honest list is in countries with zero income tax in 2026. And the American who has not yet dealt with the federal layer, because everything above concerns the local bill, and for a US citizen the local bill is the smaller half.

The order is fixed, because reversing it is what creates the expensive corrections. Answer the day-count question honestly. Choose the base around that answer rather than around the headline rate. Plan the exit from the current system in parallel with your own counsel, before a move date is fixed — I triggered Canada’s departure tax myself on the way out in 2020 and learned that lesson at full price. Settle the ownership structure. Then, and only then, layer a second citizenship on for mobility. The full sequencing sits on the tax residency page and the cross-border view on international tax planning.

Where a requirement runs past coordination into structuring executed rather than designed, the associates and I introduce a dedicated specialist private-capital practice and stay on the real-estate and residency side of the file ourselves.
