Do I have to file at home while living in Barbados?
Residence decides it, and residence is a question of facts rather than of where your post arrives. The one exception is US citizenship, which carries the filing obligation with the person wherever they go. So the first thing we establish is which system still claims you.
Is there a treaty between my country and Barbados?
That is verified rather than assumed: we confirm which treaty text governs Barbados and your home country for the year in question, because a protocol can move a rate or an article between years. If there is no treaty, unilateral credit rules are what prevent double taxation.
I own property in Barbados. Where is the rent taxed?
In Barbados, because that is where the property sits. The complication is the base: gross-rent withholding takes no account of mortgage interest, tax or repairs, so a leveraged property can face tax on turnover. An election onto net profit, where it exists, is what fixes that — and it has its own timing.
Is my old Barbados company still something I have to report?
If you hold shares in it, yes. The fact that it does little is not the test. For home-country purposes a Barbados entity is a foreign corporation, and the obligations that follow attach to ownership rather than to activity: information returns about the holding, and in some cases attribution of the company's income to you whether or not anything is distributed. A company left dormant for years is a common source of unfiled information returns, precisely because nothing happens to prompt them. The first step is to establish what the entity actually is, what it holds, and who is recorded as owning it.
Does my Barbados company still qualify for treaty benefits?
That question is now answered by substance rather than by where the company was registered. What gets examined is where decisions are actually taken, who takes them, what the company does in Barbados, and whether the arrangement has a purpose beyond obtaining the relief itself. Structures set up under an older understanding often have the registration and the certificates but not the record of governance, and a certificate of residence on its own has stopped being the end of the discussion. If the benefit matters to your returns, the evidence for it has to be built and kept year by year.
I have shares in a Barbados insurance company, what do I file?
Two things sit side by side. There is the reporting of the interest itself, which follows from owning a share in a foreign corporation, and there is the question of whether any of the company's income is attributed to you at home before it is paid out. Which attribution rules bite depends on what the company earns and how it is controlled, and insurance and investment income is usually treated less favourably than an active trade. The analysis is done on the company's own accounts, so the accounts, the share register and any shareholder agreement are the starting documents.
What does substance actually mean for a Barbados structure?
In practice, evidence that the company is directed and managed where it says it is. Board meetings genuinely held there and minuted, directors capable of taking the decisions recorded in their name, staff or outsourced functions performing the activity, premises, and books kept locally. None of this is exotic, but it has to exist contemporaneously. A file assembled after an enquiry opens is worth much less than one built as the year went along. Where the substance is thin it is better to know that before a treaty position is taken on a return.
I am on a posting in Barbados, do I stop filing at home?
Not automatically. A posting changes where you work; it does not by itself end residence at home, and for American citizens it does not end the filing obligation at all. What matters is whether the ties that made you resident have been cut or merely paused: the home you kept, the family who stayed, the accounts and memberships that carried on. Where both countries treat you as resident, the treaty decides which one is primary. Settling this at the start of the posting takes far less work than reconstructing it when you return.
Who taxes my salary while I am working in Barbados?
Ordinarily the country where the work is physically performed has the first claim on employment income, with your country of residence taxing the same income and relieving it by credit. Short assignments can fall within the treaty exemption for temporary presence, but that relief carries conditions about how long you are there and who really bears the cost of your pay. A cost recharged to a local entity usually takes the exemption away. Establishing which side of that line an assignment falls on, before the payroll is set up, avoids withholding in two places.
How do I qualify for the foreign earned income exclusion?
The exclusion means exactly what it says — foreign earned income left out of the US tax base — and to qualify you need a tax home in a foreign country and then one of two tests. The bona fide residence test asks whether you were genuinely settled there for an uninterrupted period including a full tax year — a facts-and-circumstances judgment. The physical presence test is arithmetic: a set number of full days in foreign countries within any twelve consecutive months, which you may choose to maximise the exclusion. They are alternatives, and a housing amount sits alongside. See the foreign earned income exclusion.
Do I owe state income tax if I live abroad?
Possibly, and it is the part Americans abroad most often miss. States are not parties to tax treaties, several do not follow the federal foreign earned income exclusion, and liability generally follows domicile rather than physical presence. A driver's licence, a voter registration, a home kept available and a mailing address are the facts a state weighs. Some states have no income tax at all, which is why the last state you were domiciled in matters so much. See state residency and domicile.
