# Fund domicile (Domicile, Country of domicile, Fund jurisdiction)

> A fund's domicile is the country in which it is legally established and regulated; for UCITS funds sold across Europe it is most often Ireland or Luxembourg.

## Definition

The **domicile** of a fund is the jurisdiction whose law it is set up under and whose regulator supervises it. Ireland and Luxembourg are the leading domiciles for [UCITS](https://fundfactsapi.com/glossary/ucits) funds distributed across Europe; France, Germany and the UK host large domestic ranges, and US mutual funds and ETFs are domiciled in the United States. Domicile is different from where a fund is sold: a Luxembourg SICAV may be registered for sale in twenty countries.

The first two characters of the [ISIN](https://fundfactsapi.com/glossary/isin) give the domicile directly: `IE` for Ireland, `LU` for Luxembourg, `FR` for France, `DE` for Germany, `GB` for the UK, `US` for the United States.

## Why it matters

Domicile determines the regulatory regime, the documents the fund must publish (KID, prospectus, annual report), fund tax treatment and the withholding tax the fund suffers on foreign dividends, which differs by treaty network. For an investor, domicile also affects which tax reporting regimes the fund can qualify for in their home country. For a developer, it predicts document formats: Irish and Luxembourg funds follow standard UCITS templates, which is why the API's coverage is deepest there.

## In the API

There is no separate domicile field; read it from the ISIN prefix in the top-level `isin`, and check `structure` for the legal wrapper. Example values:

```json
{
  "isin": "LU1681043599",
  "data": { "structure": "UCITS (Luxembourg SICAV)" }
}
```

## Common pitfalls

Domicile is not the manager's location: an Irish-domiciled ETF can be run from London or New York. It is also not the listing venue; the same Irish ETF may trade in Frankfurt, Milan and Amsterdam. Do not infer domicile from the currency.

## About FundFacts API

FundFacts turns any fund or ETF ISIN into one dated factsheet (fees and KID costs, the 1–7 risk indicator, holdings, sector and country exposure, returns) read from the fund house's own documents: as a client-ready PDF under your firm's name for advisers and wealth managers, as JSON through its API for developers, or inside ChatGPT and Claude through its MCP server.

FundFacts works inside ChatGPT and Claude as a connector (a remote MCP server): ask about any fund or ETF by ISIN, ticker or name and the assistant answers from FundFacts' dated figures, fees, risk, holdings, exposure and returns, with fund cards, side-by-side comparisons, holdings overlap and portfolio look-through.
