The old vs new tax regime debate has become more relevant after Budget 2025 restructured tax slabs and exemptions. The new tax regime now offers zero tax up to ₹12.75 lakh for salaried individuals, reducing tax complexity. In contrast, the old tax regime retains popular deductions like 80C and HRA, benefiting those with significant tax-saving investments.
Choosing between the old regime vs new regime depends on your financial strategy—whether you prefer structured deductions or a straightforward, exemption-free system. While the new tax regime suits taxpayers with minimal claims, those leveraging deductions may still find the old tax regime more tax-efficient.
Old vs New Tax Regime: Which Option is Better Post Budget 2025?
The old vs new tax regime debate has gained momentum following the Union Budget 2025, which introduced major tax reliefs under the new tax regime. With a zero-tax threshold extending up to ₹12.75 lakh for salaried individuals, many middle-income earners may find the new structure more beneficial.
However, the old tax regime continues to provide tax-saving opportunities through deductions such as 80C (investments), 80D (medical insurance), and HRA (house rent allowance). For taxpayers who maximize these exemptions, the traditional system might still be preferable.
Ultimately, the old regime vs new regime decision depends on individual tax planning. Those seeking simplicity may prefer the new tax regime, while deduction-heavy taxpayers might benefit more from the old tax regime.

New Tax Regime: Tax applies at 20% for the ₹16–20 lakh bracket, and only the ₹75,000 standard deduction is available.
Old Tax Regime: With substantial exemptions (HRA, 80C, 80D, home loan interest), taxable income can be reduced to a lower bracket, offering savings.
Example 3: Income = ₹14 Lakh
New Tax Regime: Taxable income remains ₹13.25 lakh after the standard deduction.
Old Tax Regime: If deductions total ₹4–5 lakh, taxable income drops significantly, making it more tax-efficient in some cases.

Old Tax Regime: Maximizing deductions can push taxable income into a lower bracket, potentially reducing overall tax liability.
Example 5: Income Above ₹24 Lakh
