Double Taxation Treaty
Reviewed by An international agreement between two states that allocates taxing rights over income and prevents the same income from being taxed twice.
A double taxation treaty (also called a double taxation agreement) is a bilateral treaty that sets the rules by which income or capital earned by a resident of one country in another country is taxed. Such treaties determine which state has the primary right to tax specific types of income — dividends, interest, royalties, income from real estate, or employment — and how double taxation is relieved, either by exemption or by crediting tax already paid abroad.
For a person changing tax residency when relocating under an investment programme, whether such a treaty exists between the former and the new country significantly affects the overall tax burden. Treaties also contain provisions on the exchange of tax information and on tie-breaker rules for determining residency in disputed cases.
The specific rates, the taxes covered, and the conditions depend on the text of each individual treaty and on the domestic law of both countries, so applying a treaty requires case-by-case analysis. This information is provided for reference and is not tax advice.
FAQ
How does a tax treaty affect a relocation?
When you change tax residency, the treaty between your former and your new country decides which state may tax dividends, interest, rental income or capital gains, and to what extent. Obtaining a residence permit or a passport does not in itself create a tax liability.
Does a treaty mean no tax is payable?
No. A treaty does not remove tax; it allocates taxing rights between the two states and eliminates double taxation of the same income, usually through an exemption or a credit. The final burden still depends on the type of income and each country's domestic law.
What if both countries treat me as their tax resident?
Treaties contain tie-breaker rules that work through a sequence — permanent home, centre of vital interests, habitual abode, then nationality — to assign residence to one state. The outcome turns on your facts and on the wording of the treaty in force.
Does a second passport entitle me to treaty benefits?
Generally not. Treaties apply to residents of the contracting states rather than to their citizens, so relief follows tax residency and not the passport you hold.
What is needed in practice to claim a reduced rate?
Typically a certificate of tax residency plus a claim filed with the payer or withholding agent before payment, and sometimes proof that you are the beneficial owner of the income. The exact procedure and forms are set by the source country.
