India extends online tax return filing period to 48 months for corrections and updates.

The Indian Income Tax Department now allows online filing of updated tax returns (ITR-U) for assessment years 2021-22 and 2022-23, extending the filing period to 48 months. Taxpayers can use ITR-1 and ITR-2 forms to correct errors and pay additional taxes, with penalties for late filing. The ITR-3 form is also available online for those with business or professional income, requiring separate reporting of capital gains before and after July 23, 2024, due to recent tax law changes. The filing deadline for non-audit cases is September 15, 2025, while those needing audits must file by October 31, 2025.
