A DTAA is a bilateral treaty between two countries that allocates taxing rights over cross-border income so that the same income is not fully taxed in both jurisdictions. India has signed over 95 such treaties.
Cross-border income gets one of three treatments under a DTAA: (a) exemption in one country (e.g., interest from NRE deposits is India-exempt under domestic law and most DTAAs do not override this), (b) reduced withholding (e.g., 10% on dividends instead of domestic 20%), or (c) credit method where both countries tax but the residence country gives credit for tax paid in the source country.
To claim DTAA benefit, an NRI typically needs: (i) TRC from the residence country, (ii) Form 10F filed electronically with the Indian portal, (iii) a self-declaration of no permanent establishment in India for business income, and (iv) the PAN.
Example 1 — India-US: A US-resident NRI receives Rs 10 lakh dividend from an Indian listed company. India taxes at 25% (DTAA rate for US) or domestic 20%, whichever is lower. The lower rate applies on filing TRC + 10F. The same dividend is reportable in the US 1040; the US gives Foreign Tax Credit (FTC) for the Indian tax paid.
Example 2 — India-UAE: A UAE-resident NRI earns interest from an NRO fixed deposit. The Indian Act withholds 30% + surcharge + cess. The India-UAE DTAA caps it at 12.5%. With TRC + 10F, the bank applies 12.5%. UAE itself does not tax this interest (no personal income tax), so no further tax abroad.
Be aware: Capital gains on Indian equity is taxed in India under most DTAAs (Article on "Gains" usually preserves source-country rights). The treaty does not eliminate Indian capital-gains tax.
