How to Choose Between Old and New Tax Regime

Choosing between old and new tax regime in India

One of the most important decisions Indian taxpayers face each year is choosing between the Old Tax Regime and the New Tax Regime. The New Regime offers lower tax rates but eliminates most deductions and exemptions. The Old Regime has higher rates but allows you to claim deductions like 80C, 80D, HRA, and more. This guide helps you understand both regimes and make the right choice for FY 2025-26.

Overview of the Two Tax Regimes

The New Tax Regime was introduced in Budget 2020 and has been revised several times since. For FY 2025-26, the New Regime is the default regime — meaning it applies automatically unless you specifically opt for the Old Regime. Self-employed individuals and those with business income must declare their choice of regime by the due date of filing, and switching back to the Old Regime later is allowed only once in a lifetime.

Tax Slabs Comparison for FY 2025-26

New Tax Regime

Up to Rs 4,00,000 — Nil
Rs 4,00,001 to Rs 8,00,000 — 5%
Rs 8,00,001 to Rs 12,00,000 — 10%
Rs 12,00,001 to Rs 16,00,000 — 15%
Rs 16,00,001 to Rs 20,00,000 — 20%
Rs 20,00,001 to Rs 24,00,000 — 25%
Above Rs 24,00,000 — 30%

Standard deduction of Rs 75,000 is available. Rebate under Section 87A makes income up to Rs 12,00,000 effectively tax-free.

Old Tax Regime

Up to Rs 2,50,000 — Nil
Rs 2,50,001 to Rs 5,00,000 — 5%
Rs 5,00,001 to Rs 10,00,000 — 20%
Above Rs 10,00,000 — 30%

Standard deduction of Rs 50,000 for salaried individuals. All deductions under 80C, 80D, HRA, LTA, and others are available.

Deductions Available in Each Regime

Under the Old Regime, you can claim: Section 80C (Rs 1.5 lakh), Section 80D (health insurance), Section 80CCD(1B) (NPS — Rs 50,000), HRA exemption, LTA, home loan interest under Section 24(b), and many more.

Under the New Regime, most of these deductions are not available. The key benefits allowed are: standard deduction of Rs 75,000, employer’s NPS contribution under Section 80CCD(2), and deduction for family pension income.

When to Choose the Old Tax Regime

The Old Regime is generally better if you have significant deductions and exemptions. Consider the Old Regime if:

Your total deductions under 80C, 80D, 80CCD, and others exceed Rs 3-4 lakh.
You pay substantial house rent and can claim HRA exemption.
You have a home loan with interest payments qualifying under Section 24(b).
You are making the most of NPS for the additional Rs 50,000 deduction.
Your income falls in the Rs 10-20 lakh range where the Old Regime’s deductions create the most savings.

When to Choose the New Tax Regime

The New Regime works better if you have minimal deductions. Choose the New Regime if:

You do not have significant investments in 80C instruments.
You live in your own house and cannot claim HRA.
You do not have a home loan.
Your income is below Rs 12 lakh (effectively tax-free under the New Regime due to the Section 87A rebate).
You prefer simplicity and do not want to track investment proofs and receipts.

How to Calculate: A Practical Comparison

Let us compare for an individual with Rs 15 lakh income, Rs 1.5 lakh in 80C investments, Rs 25,000 in 80D, Rs 2.4 lakh HRA exemption, and Rs 50,000 standard deduction:

Old Regime: Taxable income = Rs 15,00,000 – Rs 1,50,000 – Rs 25,000 – Rs 2,40,000 – Rs 50,000 = Rs 10,35,000. Tax = Rs 1,19,600 + cess = Rs 1,24,384.

New Regime: Taxable income = Rs 15,00,000 – Rs 75,000 = Rs 14,25,000. Tax = Rs 20,000 + Rs 40,000 + Rs 33,750 = Rs 93,750 + cess = Rs 97,500.

In this example, the New Regime saves more despite the deductions. The breakeven varies for each individual, which is why you should calculate for your specific situation.
