Old vs New Tax Regime (FY 2025-26): Which One Saves You More Tax?
Direct Answer: The optimal choice depends on your income and deductions. The Old Tax Regime is better only if your claimed deductions exceed a specific breakeven threshold. As derived from our comparison table below, this breakeven claimed deduction (excluding standard deduction) ranges from ₹4.5 Lakhs for a ₹10 Lakhs income, to ₹5.44 Lakhs for a ₹15 Lakhs income, up to ₹7.08 Lakhs for a ₹20 Lakhs income. Below these thresholds, the New Tax Regime is more beneficial. See the arithmetic details below.

What is the Old Tax Regime?
The Old Tax Regime levies higher progressive rates but allows taxpayers to lower their net taxable income by claiming deductions under the Income-tax Act, 1961. Eligible claims include Section 80C (up to ₹1.5 Lakhs), HRA exemption, Section 24(b) interest (up to ₹2 Lakhs), Section 80D medical premiums, and a standard deduction of ₹50,000.
The tax slabs for the Old Regime for FY 2025-26 are:
| Net Taxable Income Bracket | Old Tax Rate |
|---|---|
| Up to ₹2,50,000 | 0% (Nil) |
| ₹2,50,001 to ₹5,00,000 | 5% |
| ₹5,00,001 to ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |

What is the New Tax Regime?
The New Tax Regime is the default choice starting from FY 2023-24. It offers lower slab rates and wider bands, but removes almost all deductions. Salaried employees retain a standard deduction of ₹75,000. Taxpayers also benefit from the Section 87A rebate, making income up to ₹12 Lakhs (or a salary of ₹12.75 Lakhs after standard deduction) completely tax-free.
The tax slabs for the New Regime for FY 2025-26 are:
| Net Taxable Income Bracket | New Tax Rate |
|---|---|
| Up to ₹4,00,000 | 0% (Nil) |
| ₹4,00,001 to ₹8,00,000 | 5% |
| ₹8,00,001 to ₹12,00,000 | 10% |
| ₹12,00,001 to ₹16,00,000 | 15% |
| ₹16,00,001 to ₹20,00,000 | 20% |
| ₹20,00,001 to ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
The Key Deductions That Tilt the Balance
The key items that determine if the Old Regime is better include:
- Section 80C: EPF, PPF, ELSS, or home loan principal up to ₹1.5 Lakhs. Check headroom using our Section 80C Guide.
- HRA Exemption: Deductible rent paid to landlords. Learn rules in the HRA Exemption Guide.
- Section 24(b): Up to ₹2 Lakhs interest on self-occupied home loans.
- Section 80CCD(1B): Additional ₹50,000 invested in NPS.

How the Breakeven is Calculated (The Arithmetic)
The breakeven claimed deduction is the amount of investments and exemptions you must claim (in addition to the ₹50,000 Old Regime standard deduction) to make your Old Regime tax exactly equal to your New Regime tax. Here is how it is derived from the slabs:
- At ₹10,00,000 Income: New Regime tax is ₹0 (due to ₹75,000 standard deduction + Section 87A rebate). To get ₹0 tax under the Old Regime, net taxable income must not exceed ₹5,00,000 (due to rebate). Required total deductions = ₹10,00,000 - ₹5,00,000 = ₹5,00,000. Subtracting the ₹50,000 standard deduction, the breakeven claimed deduction is exactly ₹4,50,000.
- At ₹15,00,000 Income: New Regime tax is ₹97,500 (with cess). To match this under the Old Regime, the tax before cess must be ₹93,750. Slabs tax of ₹93,750 = ₹12,500 (on first ₹5 Lakhs) + 20% of (Taxable Income - ₹5 Lakhs) → Taxable Income = ₹9,06,250. Required total deductions = ₹15,00,000 - ₹9,06,250 = ₹5,93,750. Subtracting the ₹50,000 standard deduction, the breakeven claimed deduction is exactly ₹5,43,750.
- At ₹20,00,000 Income: New Regime tax is ₹1,92,400 (with cess). To match this under the Old Regime, the tax before cess must be ₹1,85,000. Slabs tax of ₹1,85,000 = ₹1,12,500 (on first ₹10 Lakhs) + 30% of (Taxable Income - ₹10 Lakhs) → Taxable Income = ₹12,41,667. Required total deductions = ₹20,00,000 - ₹12,41,667 = ₹7,58,333. Subtracting the ₹50,000 standard deduction, the breakeven claimed deduction is exactly ₹7,08,333.
Who Should Typically Choose the Old Regime?
Salaried individuals who pay high rent in metro cities (claiming HRA), have active home loans (claiming Section 24b interest), and maximize Section 80C investments generally find that their claimed deductions cross the breakeven threshold (which ranges from ₹4.5 Lakhs to ₹7.08 Lakhs depending on income, as derived in the arithmetic section below), making the Old Regime the more tax-efficient choice.
Who Should Typically Choose the New Regime?
Individuals who do not claim HRA (such as living in own homes), do not have home loan interest, and choose not to lock up capital in 80C instruments (preferring liquidity for direct investments) are usually better off under the New Tax Regime.
How to Switch Regimes
Salaried employees can switch between the two regimes annually by informing their employer at the beginning of the financial year and declaring it in their ITR. However, individuals with business or professional income can switch back to the old regime only once in their lifetime, after which they are locked out of switching.
Frequently Asked Questions
Which is better, old or new tax regime?
It depends on your income and eligible deductions. For salaried individuals, the Old Regime typically saves more tax only if your claimed deductions (like Section 80C, HRA, home loan interest, and NPS, excluding the standard deduction) exceed a breakeven range of ₹4.5 Lakhs to ₹7.08 Lakhs depending on your salary level. If your deductions are below this range, the New Regime is generally better.
Is income up to ₹12 lakh tax-free in the new regime?
Yes, for the financial year 2025-26, the Section 87A rebate is available up to ₹60,000 in the New Tax Regime. This renders taxable income up to ₹12 Lakhs (equivalent to ₹12.75 Lakhs of salary for employees after the ₹75,000 standard deduction) effectively tax-free.
Can I switch between regimes every year?
Yes, salaried employees who do not have business or professional income can switch between the old and new tax regimes every year at the time of filing their ITR. If you have business income, you can switch back to the old regime only once in your lifetime.
What deductions are allowed in the new regime?
The New Tax Regime does not allow popular deductions like Section 80C, HRA, or Section 24 interest on self-occupied house loans. However, it does allow the ₹75,000 standard deduction for salaried employees, family pension deductions, and employer contributions to NPS under Section 80CCD(2).
