How to Use the Income Tax Calculator
Enter your gross annual income, deductions under various sections, and HRA details. Select the financial year and click Calculate. The tool computes your tax under both the old and new regime, shows a side-by-side comparison, and recommends which regime saves you more money.
Old vs New Tax Regime — Key Differences
The Old Regime allows deductions under Sections 80C, 80D, HRA exemption, and other sections, but has higher tax slab rates. The New Regime (introduced in Budget 2020, updated in 2023) offers lower slab rates but with almost no deductions except the standard deduction. Most salaried employees with significant deductions (80C + HRA) benefit from the Old Regime, while those with fewer deductions benefit from the New Regime.

Frequently Asked Questions
Which tax regime is better — old or new?
It depends on your deductions. If your total deductions (80C, 80D, HRA, NPS) exceed ₹3.75 lakh, the old regime may save more. Otherwise, the new regime with its lower slab rates and ₹12.75 lakh zero-tax threshold (FY 2026-27) is usually better.
