<h1>New Tax Regime Default for 2024-25: Procedures for Opting Old Regime, Filing ITRs, and Comparing Tax Liabilities.</h1> For the assessment year 2024-25, the New Tax Regime is the default for individuals, Hindu Undivided Families (HUFs), Associations of Persons (AOPs), Bodies of Individuals (BOIs), and Artificial Juridical Persons. Those wishing to opt for the Old Tax Regime must follow specific procedures: if eligible to file returns using ITR 1 or 2, select the relevant option directly in the ITR and file by the due date. For ITR 3, 4, or 5, filing Form 10-IEA before the due date under section 139(1) is mandatory. Taxpayers should compare liabilities under both regimes before filing.
