CaribTax / Private Client / International & Cross-Border

International and Cross-Border

Aligning legal structure, operations and tax outcome across more than one jurisdiction.

When this applies

You are tax resident in one place, incorporated in another, and generating income in a third.
You have been told you are 'no longer resident' somewhere without anyone testing that against the other jurisdiction's own rules.
A holding or financing structure sits between operating entities and nobody has confirmed it still has substance behind it.
You are being asked to certify residency or beneficial ownership to a bank, a registry or a counterparty.
Two sets of advisors in two countries have each assumed the other is handling something.

What it costs when this goes wrong

Double taxation is the visible failure

Being taxed twice on the same income is the outcome clients notice. It is also, frequently, the recoverable one. The unrecoverable failures are quieter.

Dual residency creates obligations in both places

Falling resident in two jurisdictions at once does not average the two positions. It creates filing, disclosure and payment obligations in both, often with inconsistent deadlines and inconsistent definitions of the same income.

Substance failures unwind the whole structure

Where a structure depends on functions being performed in a particular place and they demonstrably are not, the arrangement can be disregarded in its entirety. The fallback position is rarely the one the client would have chosen.

What we do

Assessment of tax residency under each relevant jurisdiction's rules rather than by assumption.
Review of holding and financing structures for substance, purpose and consistency with how the business actually runs.
Analysis of where functions, assets and risks genuinely sit, and whether the legal structure reflects that.
Identification of mismatches between jurisdictions that create double taxation or an unclaimed relief.
Coordination with advisors in the other jurisdictions so that no question is assumed to be someone else's.

How an engagement runs

Four stages, specific to this work.

Map the connections

Every jurisdiction with a claim: where you are, where the entities are, where the income arises, where the assets sit, where the decisions are actually taken.

Test residency properly

Status assessed against each jurisdiction's own tests rather than assumed from where you spend most of the year, which is only one factor and rarely the decisive one.

Locate the mismatches

The gaps and overlaps between jurisdictions, which is where the exposure and the unclaimed relief both sit, and which neither country's advisor is usually looking at.

Coordinate the fix

Implementation here and coordination with qualified advisors elsewhere, with someone holding responsibility for the combined result rather than each piece.

What you end up holding

A jurisdiction map showing every country with a claim and the basis of that claim.
A residency assessment for each relevant jurisdiction, with the facts each conclusion depends on.
An analysis of where the jurisdictions conflict and what that costs or offers.
An evidence schedule: what you should be keeping, from now, to support the position if it is later examined.

What people get wrong

Three beliefs that cost clients money.

“I spend under half the year there, so I am not resident.”

Day count is one test among several and often not the decisive one. Where your home is, where your family is and where your economic centre sits can each outweigh it. Advice built only on counting days is incomplete.

“I told them I was leaving, so I have left.”

Notifying a jurisdiction that you have departed does not by itself end residency there. Most countries apply their own tests, and several continue to assert residency for a defined period regardless of what has been notified.

“My advisors in both countries have it covered.”

Each will answer correctly within their own jurisdiction. Neither is usually engaged to ask what happens when the two answers are placed side by side, and that gap is where most cross-border failures live.

How the position is approached

Cross-border positions fail in a predictable way. Each jurisdiction is looked at in isolation, by an advisor who is competent in that jurisdiction, and the failure occurs in the space between them. Residency is the most common example: it is entirely possible to satisfy the departure test in one country while never satisfying the arrival test in another, or to satisfy both and be treated as resident in two places at once.

The second recurring failure is substance. A structure is designed on the assumption that certain functions will be performed in a certain place, and then the business runs differently in practice. The legal form and the operational reality drift apart. What matters when the position is examined is not the intention recorded at incorporation but what can actually be evidenced about how decisions were made and where.

The approach is therefore to work from the operations backwards to the structure, rather than from the structure forwards. We establish where decisions are genuinely taken, where people genuinely are, and where value is genuinely created, and then test whether the legal arrangement is a fair description of that. Where it is not, the choice is either to change the structure or to change the operations, and that is a business decision the client makes with full sight of the trade-off.

The evidential dimension deserves separate attention because it is the one clients most often dismiss. Cross-border positions turn on facts: where a person was, where a meeting happened, who took a decision and where they were when they took it. Those facts are cheap to record at the time and extremely expensive to reconstruct three years later from calendars, boarding passes and memory. A client who begins keeping a simple contemporaneous record from the start of an engagement has materially improved their position without changing anything about how they operate.

There is also a coordination failure that is structural rather than technical. Where a client has competent advisors in two countries, each will answer the question they are asked, correctly, within their jurisdiction. Neither is engaged to ask what happens when the two answers are placed side by side. That question has to be somebody's job, explicitly, or it does not get asked at all.

Common questions

Do you advise on the tax rules of other countries?

We advise on the Sint Maarten position and on how it interacts with other jurisdictions. Where a definitive position is needed under another country's domestic law, we coordinate with qualified advisors there rather than opine on it ourselves.

Can you tell me whether I am tax resident in Sint Maarten?

That is one of the most common questions a Position Review answers. It depends on facts that need to be established rather than assumed, which is why it is assessed at the review stage rather than over a phone call.

What if I have been filing on the wrong basis?

It is addressed rather than left. The route depends on how long the position has run and what has already been filed, and it is set out in writing with the options and their consequences.

Is a holding structure still worth having?

Sometimes. The answer depends on what the holding entity actually does, not on what type of entity it is. Structures that exist only on paper have become materially harder to defend.

Do you handle the filings in the other jurisdiction?

Not directly, with the exception of US expatriate reporting, which is handled by a separate CaribTax service line. For other jurisdictions we coordinate rather than file.

How many days can I spend somewhere before it matters?

Day counts are one test among several and are frequently not the decisive one. Where your home is, where your family is, where your economic interests sit and where you are registered can each outweigh a day count. Advice built only on counting days is incomplete.

What if the two countries reach different conclusions?

That happens, and where a treaty applies it usually contains tie-breaker provisions intended to resolve it. Whether those provisions help depends on the specific facts, which is why the assessment precedes the advice.
