The Income Tax Department is alerting taxpayers via SMS and email about pending refunds, often citing "risk management process" or mismatches in income and deductions. Affected individuals are advised to file a revised Income Tax Return (ITR) by December 31, 2025, to correct errors in their original filing. A revised ITR can fix issues like unreported income or incorrect deductions without penalty if filed within the deadline. If this deadline is missed, taxpayers may need to file an 'updated return' (ITR-U), which could incur additional tax liabilities or penalties.
