The tax treatment of interest earned by NRIs depends on the specific type of account holding the deposit. According to reports from Mint, interest on Non-Resident Ordinary (NRO) accounts is taxable in India at 30% plus applicable surcharge and cess. In contrast, interest on Non-Resident External (NRE) accounts is tax-free in India, subject to applicable conditions. Similarly, interest on Foreign Currency Non-Resident (FCNR) accounts is tax-free in India, subject to applicable conditions. These different tax treatments reflect the varying purposes and structures of these banking products designed for non-resident Indians. As per CA (Dr.) Suresh Surana, interest earned on an eligible NRE deposit is exempt from tax in India under Section 11 read with Schedule IV of the Income-tax Act, 2025, provided the account holder satisfies the prescribed FEMA conditions. Interest on a qualifying FCNR(B) deposit is also generally exempt, subject to the applicable conditions. Both NRE and FCNR(B) deposits are repatriable, though an NRE deposit is denominated in Indian rupees and therefore exposes the investor to currency fluctuations.
Despite the tax implications, NRIs can avoid paying tax twice through the Double Taxation Avoidance Agreement (DTAA) signed by India with 90 countries. As reported by Mint, under DTAA, NRIs can earn tax credits for tax paid in India against their tax liability in their country of residence. To avail these benefits, NRIs must submit specific documents including a tax residency certificate issued by their country of residence and a self-declaration format to their chartered accountant to deduct tax at source in India. This mechanism helps prevent double taxation on the same income. According to Financial Express, where a Double Taxation Avoidance Agreement (DTAA) provides a more beneficial rate, the taxpayer may claim treaty relief under Section 159 of the Income Tax Act, 2025 (corresponding to section 90 of the Income Tax Act, 1961), subject to furnishing the prescribed documentation, including the Tax Residency Certificate and Form 41 (previously Form 10F).
Before determining tax liability, NRIs must establish their residential status under Indian income tax law. According to Mint reports, a foreign citizen becomes a 'Resident' under Section 6(1) of the Income Tax Act if they stay in India for 182 days or more during the financial year (1 April to 31 March). Alternatively, they become a resident if they stay in India for 60 days or more in the current financial year and have spent 365 days or more in India across the preceding four financial years. For individuals, residential status is further classified as Resident-Ordinarily Resident and Resident but not Ordinarily Resident. As per Financial Express, tax-free in India does not mean tax-free in the country where the NRI resides. Countries like the USA, UK and Singapore tax residents on worldwide income, so NRE or FCNR interest that India exempts may still be taxable in the NRI's country of residence. The UAE, Oman and Qatar levy no personal income tax, so GCC-based clients typically enjoy the India exemption with nothing owed at home.
The tax landscape for NRIs has been influenced by recent policy changes, particularly the government's announcement of a special foreign-currency deposit window for NRIs in June 2026. As reported by Mint, this scheme allows non-resident Indians to place leveraged and unlevered deposits with Indian banks in foreign currency while the Reserve Bank of India (RBI) takes the hedging risk. This facility is designed to attract overseas funds and will remain available until the end of September. The policy changes reflect the government's efforts to facilitate easier access to foreign currency banking for NRIs.
For NRIs looking to invest their surplus money in India, fixed deposits and debt mutual funds can both appear attractive. According to Financial Express analysis, the NRE fixed deposit provides the highest post-tax amount, exceeding the debt mutual fund by approximately ₹46,361 since its entire 7% return is exempt from tax in India. The debt mutual fund earns a higher pre-tax return of 8%, but taxation reduces its effective post-tax return to approximately 5.63%. The debt mutual fund performs better than the NRO fixed deposit by approximately ₹27,132 due to higher pre-tax returns and tax deferral until redemption. An eligible NRE or FCNR(B) deposit may be preferable where predictable returns, capital stability and tax-exempt Indian income are the principal objectives. Debt mutual funds may be considered where liquidity, diversification and potential returns justify the additional risk. The final comparison should be based on investment factors, post-tax returns in India, repatriation requirements and taxation in the NRI's country of residence, since income exempt in India may still be taxable overseas.
