Double Taxation Avoidance Agreement

DTAA

Double Taxation Avoidance Agreement is a bilateral treaty allocating taxing rights between two countries to prevent the same income being taxed twice.

What DTAA is

A Double Taxation Avoidance Agreement (DTAA), also called a tax treaty or Double Taxation Convention, is a bilateral treaty between two countries. It allocates taxing rights over cross-border income and provides relief mechanisms (credit or exemption) when both countries would otherwise tax the same income. Most DTAAs follow the OECD or UN model conventions, with country-specific variations.

What it covers

A typical DTAA covers business profits (subject to a permanent establishment), dividends, interest, royalties, capital gains, employment income, directors' fees, pensions, government service, students, and the elimination of double taxation. It also includes a residency tie-breaker, a non-discrimination clause, a Mutual Agreement Procedure (MAP), and increasingly an exchange-of-information article.

Treaty access

To claim DTAA benefits, a taxpayer must be resident in one of the contracting states, often hold a Tax Residency Certificate (TRC), and pass any anti-abuse test such as the Principal Purpose Test (PPT) introduced by the OECD Multilateral Instrument (MLI). Without these, the payer must apply domestic withholding rates.

When you will meet DTAA

You will rely on a DTAA whenever cross-border payments flow between group companies (dividends, interest, royalties, services), whenever an executive becomes tax-resident in a second country, when claiming foreign tax credits, and when defending a permanent-establishment exposure during tax audits.
