Key points
- File if your Indian income exceeds ₹4 lakh (new regime) or you have Indian capital gains.
- Filing is the only way to recover excess TDS on NRO interest, rent or property sales.
- NRIs can't use ITR-1. Check the portal for current form names under the 2025 Act.
- The usual due date for non-audit cases is 31 July after the tax year ends.
Many NRIs assume that because TDS has already been deducted, they don't need to file an Indian tax return. Often the opposite is true: filing is either required, or it's the only way to get excess TDS back.
When an NRI must file
- Your total Indian income is above the basic exemption limit: ₹4 lakh under the new regime, ₹2.5 lakh under the old. NRIs don't get the higher limits that resident senior citizens get.
- You have capital gains in India, for example from selling property, shares or mutual funds.
- You want to carry forward a loss, such as a capital loss or a house-property loss under the old regime.
When filing makes sense even if not required
- Refunds: banks deduct 31.2% on NRO interest and tenants 31.2% on rent. If your real tax is lower, filing is the only way to get the difference back.
- Treaty rates: if your bank didn't apply your DTAA rate, claim it in the return.
- Paper trail: returns help when repatriating money, applying for a lower TDS certificate or answering a tax notice.
Which return form?
Under the 1961 Act, NRIs without business income usually filed ITR-2, and ITR-3 if they had business or professional income. NRIs can't use ITR-1. Returns for income from tax year 2026-27 onward are filed under the Income-tax Act, 2025. Check the e-filing portal for the current form names before you file.
Due dates
For individuals who don't need a tax audit, the due date has historically been 31 July after the end of the tax year. A belated or revised return can usually be filed until 31 December. Due dates are sometimes extended, so check the portal each year.
What you'll need
- PAN linked to your e-filing account (NRIs don't need to link Aadhaar unless they have one)
- Annual Information Statement (AIS) and Form 26AS from the portal, to match TDS credits
- Bank interest certificates, rent records, capital gains computations
- Your Indian bank account (NRO or resident) pre-validated on the portal for refunds
- TRC and Form 10F if you're claiming treaty rates
