Old vs New Tax Regime 2026-27: Which One Should You Choose?

Confused between the old and new income tax regime? This guide compares slabs, deductions and tax on a real example so you can decide with confidence.

Updated: October 2026 · Antokia Guide

India has two income tax regimes. The new regime has lower rates but allows very few deductions. The old regime has higher rates but lets you reduce tax through deductions like 80C, 80D, HRA and home loan interest. Which one saves more depends on how much you can actually claim.

Quick answer: If your total deductions are small, the new regime usually wins. If you claim large deductions (home loan, HRA, 80C, 80D, NPS), the old regime can win. The only reliable way is to calculate both, which you can do free with the Income Tax Calculator.
Note: From 1 April 2026 the Income Tax Act, 2025 uses the term "Tax Year" instead of "Financial Year" and "Assessment Year". The slabs below are the ones shown on the official income tax portal when this guide was written. Always confirm on incometax.gov.in before filing.

New Regime Slabs

Taxable incomeTax rate
Up to Rs 4,00,000Nil
Rs 4,00,001 to Rs 8,00,0005%
Rs 8,00,001 to Rs 12,00,00010%
Rs 12,00,001 to Rs 16,00,00015%
Rs 16,00,001 to Rs 20,00,00020%
Rs 20,00,001 to Rs 24,00,00025%
Above Rs 24,00,00030%

The standard deduction is Rs 75,000 for salaried people. A section 87A rebate of up to Rs 60,000 applies if taxable income is up to Rs 12 lakh, so tax is zero up to that level (about Rs 12.75 lakh salary for a salaried person). Add 4% health and education cess on the tax.

Old Regime Slabs (below 60 years)

Taxable incomeTax rate
Up to Rs 2,50,000Nil
Rs 2,50,001 to Rs 5,00,0005%
Rs 5,00,001 to Rs 10,00,00020%
Above Rs 10,00,00030%

The standard deduction is Rs 50,000. The rebate is Rs 12,500, so there is no tax if taxable income is up to Rs 5 lakh. Senior citizens get a higher basic exemption (Rs 3 lakh at 60+, Rs 5 lakh at 80+).

Worked Example: Rs 15 Lakh Salary

Assume a salaried person with Rs 15,00,000 income. Tax below includes 4% cess and is calculated with the slabs above.

CaseTaxable incomeApprox. tax
New regime (no deductions except standard)Rs 14,25,000Rs 97,500
Old regime with only 80C (Rs 1.5 lakh)Rs 13,00,000Rs 2,10,600
Old regime with 80C, NPS Rs 50k, 80D Rs 25k and home loan interest Rs 2 lakhRs 10,25,000Rs 1,24,800

Even with heavy deductions the old regime costs more in this example. At higher deductions, such as a large HRA claim on top of the above, the gap can close. Your own numbers decide it.

Step 2: Calculate both regimes

Use the Income Tax Calculator with the same income for both.

Step 3: Compare the final tax
