Deciding between the old and new tax regimes requires a comparative calculation of your income, deductions, and exemptions. Generally, the new regime is better if you have few deductions, offering lower tax rates and simplicity. The old regime is better if you have substantial deductions (e.g., HRA, home loan interest, Sec 80C/80D).
The Old vs New Tax Regime debate centers on tax slabs and deductions. Income up to ₹12 lakh is tax-free under the new regime, due to rebate. Beyond ₹25 lakh, the old regime is better if deductions exceed ₹8 lakh. Between ₹12 - 25 lakh, the choice depends on your deduction level.
Salaried Individuals can switch between the two regimes every financial year when filing his/her tax returns. Individuals with Business Income can opt for Old Tax Regime only once and if this option is chosen, he has to file Form No. 10-1E on/before the date of filing the ITR.
Opting for 115BAC is beneficial if you prefer lower tax rates without claiming common deductions and exemptions. However, if you benefit more from deductions like HRA, home loan interest, and 80C, the old regime might be better.
Home loan tax benefits remain unchanged under the old tax regime, and you can find all the details in the sections below. However, if you have opted for the new tax regime, you will not be eligible for any tax benefits under Sections 80C, 24(b), 80EE, or 80EEA—except for one exception.

If your eligible deductions, such as under Sections 80C, 80D, home loan interest (Section 24), and HRA exemptions, add up to Rs.
