Income Tax: Old vs New Regime — Which is Better?

Choosing between the old and new income tax regimes is one of the most important financial decisions salaried employees and taxpayers in India face each year. The new tax regime, which became the default from FY 2023-24, offers lower tax rates but removes most deductions and exemptions. The old regime retains all deductions but has higher base rates. This guide helps you understand both regimes and determine which one saves you more money.

New Tax Regime — Tax Slabs (FY 2025-26)

The new regime offers these tax slabs with a standard deduction of Rs 75,000:

• 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%

Tax rebate under Section 87A makes income up to Rs 12,00,000 effectively tax-free under the new regime (after standard deduction of Rs 75,000, taxable income up to Rs 12,00,000 qualifies for full rebate).

Old Tax Regime — Tax Slabs

• 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 applies. Plus, you get access to all deductions and exemptions like 80C, 80D, HRA, LTA, and more.

Key Deductions Available Only in Old Regime

• Section 80C (Rs 1.5 lakh): EPF, PPF, ELSS, life insurance premiums, home loan principal, children's tuition fees, and more.
• Section 80D (Rs 25,000 to Rs 1 lakh): Health insurance premiums for self, family, and parents.
• HRA Exemption: Significant savings if you live in rented accommodation.
• Section 24(b) (Rs 2 lakh): Home loan interest deduction for self-occupied property.
• LTA Exemption: Leave Travel Allowance for domestic travel.
• Section 80E: Interest on education loan (no upper limit).
• Section 80TTA/80TTB: Savings account interest deduction.

Practical Comparison with Examples

Example 1: Income Rs 10 Lakh, Low Deductions

Suppose your gross income is Rs 10,00,000 and your total deductions are only Rs 2,00,000 (Rs 1.5 lakh in 80C and Rs 50,000 standard deduction):

• Old Regime: Taxable income = Rs 8,00,000. Tax = Rs 75,000 (after 87A rebate considerations). Effective tax = approximately Rs 75,000.
• New Regime: Taxable income = Rs 9,25,000 (after Rs 75,000 standard deduction). Tax = Rs 20,000 + Rs 12,500 = Rs 32,500 approximately.
• Winner: New Regime saves approximately Rs 42,500.

Example 2: Income Rs 15 Lakh, High Deductions

Suppose your gross income is Rs 15,00,000 with total deductions of Rs 4,50,000 (Rs 1.5 lakh 80C + Rs 1.5 lakh HRA + Rs 50,000 standard deduction + Rs 50,000 80D + Rs 50,000 NPS 80CCD):

• Old Regime: Taxable income = Rs 10,50,000. Tax = approximately Rs 1,32,500 + 4% cess.
• New Regime: Taxable income = Rs 14,25,000. Tax = approximately Rs 1,53,750 + 4% cess.
• Winner: Old Regime saves approximately Rs 21,250.

General Guidelines

• If your total deductions and exemptions exceed Rs 3.75 lakh, the old regime is usually better.
• If your deductions are less than Rs 3.75 lakh, the new regime is usually better.
• If your income is up to Rs 12 lakh, the new regime is almost always better due to the enhanced rebate.
• High HRA claimants (those paying high rent in metros) often benefit more from the old regime.
• Those with home loans (interest deduction under Section 24b) often find the old regime more beneficial.
