The base due date is 31 July following the financial year, so 31 July 2026 for FY 2025-26 if you file ITR-2. If you file ITR-3, because you also have Indian business or professional income and are not under audit, the due date is now 31 August 2026. A belated return can be filed up to 31 December 2026 with a late fee, and a revised return up to 31 March 2027. If you only have refunds due and miss the window, past years can still be claimed through a condonation request under Section 119(2)(b).
Most NRIs use ITR-2, which covers interest, rent, dividends, capital gains and foreign assets. ITR-3 applies if you also have Indian business or professional income. NRIs cannot use ITR-1 (Sahaj) or ITR-4 (Sugam), both are resident-only; filing one by mistake forces a revised return and delays the refund, so the form choice matters.
No, and this catches many NRIs out. The new regime is the default, and its slabs run nil up to 4 lakh, then 5% to 8 lakh, 10% to 12 lakh, and up from there. But the Section 87A rebate that makes income up to 12 lakh effectively tax-free is only for residents. As an NRI you do not get it, so you pay tax from the first rupee above the 4 lakh basic exemption. A salaried NRI still gets the 75,000 standard deduction, just not the rebate.
Once the return is filed and e-verified, refunds typically credit to your NRO account in about three to six months, depending on CPC processing and whether the return is picked for a check. Where the refund is delayed past the due date, interest is added under Section 244A. We track it weekly until the money lands.
