NRI Taxation in India — DTAA, TDS, Residential Status & Filing

The Indian taxation framework for Non-Resident Indians is built on a foundational principle: only income that is earned, received, or deemed to accrue in India is subject to Indian income tax for NRIs. This stands in contrast to Resident Indians, who are taxed on their global income. Understanding this distinction is the cornerstone of NRI tax planning and can result in significant tax savings when structured correctly.

The determination of residential status is the first critical step. Under Section 6 of the Income Tax Act, an individual is considered a Non-Resident if they have been in India for less than 182 days during the financial year (April 1 to March 31). However, there are important exceptions. Indian citizens leaving India for employment or crew members of Indian ships get a more generous threshold of 60 days. From FY 2020-21, the Finance Act introduced a "deemed resident" provision: Indian citizens with Indian income exceeding INR 15 lakhs who are not tax residents of any other country are deemed resident if they are in India for 120 days or more. This specifically targets individuals in zero-tax jurisdictions like the UAE, Bahamas, or Cayman Islands.

Once residential status is established, the next step is identifying which income is taxable in India. For NRIs, the taxable income heads include: salary for services rendered in India (even if deposited abroad), rental income from Indian property, capital gains from sale of Indian assets (shares, mutual funds, property), interest on NRO accounts and FDs, dividend income from Indian companies, and income from business connections in India. Notably, NRE and FCNR account interest is specifically exempt, making these accounts extremely attractive for parking funds.

TDS (Tax Deducted at Source) rates for NRIs are significantly higher than for residents. Where a resident might face 10% TDS on FD interest, an NRI faces 30%. Where a resident seller has 1% TDS on property sale, an NRI seller faces 12.5% to 30% of the entire sale consideration. This asymmetry frequently results in excess TDS deduction, making Indian tax return filing essential for NRIs to claim refunds. NRIs can also apply for lower TDS certificates under Section 197, where the Assessing Officer issues a certificate allowing the payer to deduct TDS at the actual applicable rate rather than the statutory NRI rate.

The Double Taxation Avoidance Agreement (DTAA) framework is the most powerful tool in the NRI tax planning arsenal. India has DTAA treaties with over 90 countries, and under Section 90 of the Income Tax Act, a taxpayer can choose the more beneficial treatment between domestic law and the DTAA treaty. This means if the DTAA rate for interest is 15% but the domestic NRI rate is 30%, the NRI can pay at 15% by furnishing a Tax Residency Certificate (TRC) and Form 10F. The DTAA also provides for Foreign Tax Credit, where taxes paid in India can be credited against the tax liability in the country of residence, preventing the same income from being taxed twice.

Filing requirements for NRIs are often misunderstood. NRIs must file an Indian tax return if their gross total Indian income exceeds the basic exemption limit (INR 3 lakh under the new regime). Even where TDS covers the entire liability, filing is advisable to claim refunds on excess TDS, carry forward capital losses, and maintain a clean compliance history. The Indian tax return must be filed by July 31 of the assessment year (or October 31 if audit applies). Belated returns can be filed until December 31 with a late fee of INR 5,000 (INR 1,000 if income is below INR 5 lakh).

For NRIs in countries with worldwide taxation (US, Canada, Australia, UK), the interplay between Indian and domestic tax obligations requires careful planning. The general principle is that you report worldwide income in your country of residence and claim Foreign Tax Credits for Indian taxes paid. This ensures you pay the higher of the two countries' rates, not both. Documentation is critical: maintain TDS certificates (Form 16, 16A, 16B), filed Indian tax returns, and DTAA forms (TRC, Form 10F) for claiming credits in your home country.
