How does the UK-Thailand double tax treaty actually work?
Many people hear the words "double tax treaty" and assume it means they will not pay tax.
That is not quite right.
A double tax treaty usually helps decide:
- Which country has taxing rights
- Whether both countries can tax the same income
- Whether one country must give credit for tax paid in the other
- How different types of income are treated
The important point is that every income type must be checked separately.
Rental income, pensions, dividends, employment income, director fees and capital gains can all have different treatments.
The treaty is useful, but it does not replace tax filing obligations or record keeping.
For UK expats in Thailand, the practical questions are:
- Where are you tax resident?
- What income do you receive?
- Where is that income sourced?
- Has it been remitted?
- What tax has already been paid?
