The Finance Act 2023 has made the new tax regime under Section 115BAC the default tax regime for individuals, HUFs, AOPs (excluding co-operative societies), BOIs, and Artificial Juridical Persons from AY 2024-25 onwards. However, taxpayers still have the option to opt out and choose the old tax regime.
Non-business taxpayers can make this choice annually in their ITR, while business taxpayers must submit Form 10-IEA before the due date under Section 139(1) to opt out or re-enter the new regime. Below are some frequently asked questions (FAQs) to help taxpayers understand the differences and implications of both tax regimes.

Which tax regime is better?
It depends on individual financial situations. Taxpayers should compare tax liabilities under both regimes using the Income Tax Calculator on the Income Tax Portal.
Do employees need to inform their employers about their chosen tax regime?
Yes, employees must inform their employers; otherwise, tax will be deducted under the default new tax regime. However, final selection occurs while filing ITR.
