Income Tax Slabs Comparison: Is the Old or New Tax Regime Better for You?

Last Updated: June 2026 • By Tushar Gupta

Filing income tax in India has undergone a major shift in recent years. With the introduction of the New Tax Regime, which is now the default option, taxpayers face a crucial choice every financial year: Should they stick with the familiar Old Tax Regime or opt for the New Tax Regime? The answer depends entirely on your income level and the amount of tax-saving investments you make. This guide compares both tax systems, explains the break-even math, and provides clear decision guidelines.

1. Slabs at a Glance (FY 2024-25 / AY 2025-26)

The two regimes have completely different tax structures and rates:

New Tax Regime Slabs

The New Tax Regime is designed with lower tax brackets to reduce the tax burden on middle-income groups who do not have large investments. The slabs are:

• Up to ₹3,00,000: Nil
• ₹3,00,001 - ₹7,00,000: 5% (with complete tax rebate up to ₹7 Lakhs taxable income under Section 87A)
• ₹7,00,001 - ₹10,00,000: 10%
• ₹10,00,001 - ₹12,00,000: 15%
• ₹12,00,001 - ₹15,00,000: 20%
• Above ₹15,00,000: 30%

Salaried individuals in the New Regime receive a flat standard deduction of ₹75,000.

Old Tax Regime Slabs

The Old Tax Regime features higher tax rates, but allows taxpayers to significantly reduce their taxable income by claiming various deductions and exemptions. The slabs are:

• Up to ₹2,50,000: Nil
• ₹2,50,001 - ₹5,00,000: 5% (with tax rebate up to ₹5 Lakhs taxable income)
• ₹5,00,001 - ₹10,00,000: 20%
• Above ₹10,00,000: 30%

Salaried individuals in the Old Regime receive a standard deduction of ₹50,000.

2. The Core Trade-off: Lower Rates vs. Exemptions

The choice between the two regimes is a trade-off:

• The New Tax Regime gives you lower slab rates and a higher tax rebate, but you must sacrifice almost all deductions.
• The Old Tax Regime taxes your income at higher rates, but lets you claim deductions like Section 80C (PPF, ELSS, Life Insurance), Section 80D (Health Insurance), Section 24(b) (Home Loan Interest), and House Rent Allowance (HRA) to bring down your taxable income.

3. The "Break-Even Point" Concept

The break-even point is the specific amount of deductions you need to claim under the Old Regime to make your tax liability identical to the New Regime.

• If your actual deductions are **higher** than the break-even point, you should choose the **Old Tax Regime**.
• If your actual deductions are **lower** than the break-even point, you should choose the **New Tax Regime**.

Step-by-Step Break-Even Example

Let us calculate the break-even point for a taxpayer with a gross annual salary of ₹15,00,000.

1. Under the New Regime:
   Taxable Income = Gross (₹15,00,000) - Standard Deduction (₹75,000) = ₹14,25,000.
   Tax Calculation across New Slabs:
   • ₹0 - ₹3L: Nil
   • ₹3L - ₹6L (5%): ₹15,000
   • ₹6L - ₹9L (10%): ₹30,000
   • ₹9L - ₹12L (15%): ₹45,000
   • ₹12L - ₹14.25L (20%): ₹45,000 (20% of ₹2,25,000)
   Total New Regime Tax = ₹1,35,000 (excluding health & education cess).
2. Under the Old Regime:
   To make your tax under the Old Regime exactly ₹1,35,000 (matching the New Regime):
   Taxable income under Old Slabs must be brought down to ₹9,83,333.
   Deductions required = Gross (₹15,00,000) - Target Taxable Income (₹9,83,333) = ₹5,16,667.
   Subtracting the Old Regime standard deduction of ₹50,000, you need investments/allowances totaling **₹4,66,667** to break even.

If your HRA, Section 80C, 80D, and Home Loan interest deductions total more than ₹4.66 Lakhs, select the Old Tax Regime. Otherwise, the New Tax Regime is more beneficial.

4. Summary Decision Guidelines

As a rule of thumb, you should choose:

Choose the New Tax Regime if:

• You prefer not to lock up your cash in long-term tax-saving investments (like 5-year FDs, PPF, or ELSS mutual funds).
• You do not have a home loan and do not live in rented accommodation (no HRA claims).
• You want a higher net monthly take-home salary to manage immediate expenses.

Choose the Old Tax Regime if:

• You are actively paying off a home loan (deducting up to ₹2 Lakhs interest under Section 24b).
• You live in a rented house and receive a high HRA component.
• You are committed to long-term savings products (EPF, PPF, NPS, Life and Health insurance premiums).
