Tax residency - Tax residency
The country where you pay taxes — usually where you live 183+ days a year. Key point: citizenship does not equal tax residency. A Grenada passport does not make you a tax resident of Grenada.

02 / In plain words
What Tax residency means
Tax residence is the country to which you must pay tax on your income. Usually it is the country where you physically spend most of the year: almost everywhere the threshold is 183 days in 12 months. But other ties are taken into account too: where your home, family and main business are — your centre of vital interests.
The thing most often confused: citizenship and tax residence are different things. A Grenadian or St Kitts passport does not make you a Caribbean tax resident and does not by itself change where you pay tax. You remain a tax resident of the country where you actually live until you physically move your centre of life.
That is why a second passport and a change of tax status are planned separately. For a country to let you go as a resident, leaving for a couple of weeks is not enough: you need to spend more than half the year outside it, and sometimes also obtain residence in the new country and sever old ties. Some states have an exit tax on departure — a tax on unrealised gains on assets, calculated before the move.
A case from practice
An entrepreneur obtains a Grenadian passport but continues to live in their previous country for more than 183 days a year. They still pay tax where they did before — the Caribbean passport has no effect on that. To really change tax residence, they need to move their centre of life: spend most of the year in another jurisdiction and obtain resident status there.

06 / Expert advice
How to prepare in advance
Before relocating, establish frankly where you are a tax resident now and what a new status will actually change. It is important to calculate any exit tax, check the CFC rules on your companies and understand which ties (home, family, business) need to be moved. Then the change of residence goes through without additional assessments or disputes between countries.
What we do for you. We review your situation before you apply: where you are a tax resident now, what a new status will and will not do for your taxes, and whether exit tax and CFC rules apply on departure. You get a straight picture in advance and do not build plans on the mistaken assumption that a passport automatically changes your taxes.

07 / Questions
Frequently asked questions
Not by itself. As long as you live in your previous country for more than 183 days a year, you remain its tax resident. Taxes change when you physically move your centre of life; obtaining a second passport has no effect on that.
Yes, it happens if both countries regard you as theirs under their own rules. The dispute is then settled by the double tax treaty between those countries — a chain of tie-breaker criteria determines a single one.
If you have spent 183 days or more in a country in 12 months, it usually regards you as a tax resident. But it is not the only criterion: a permanent home, family and centre of interests are also taken into account.
It is a tax some countries levy when you leave their tax residence — on unrealised gains in the value of assets, as if you had sold them at the moment of departure. It is calculated in advance.
Under CRS, the bank reports your account data specifically to your country of tax residence. That is why it matters to determine it clearly — otherwise the data will go somewhere other than you expect.
No. You need to spend most of the year outside the country, sever ties (home, family, business) and, as a rule, become a resident of another country. Otherwise your previous country will continue to regard you as its own.
