Old vs New Tax Regime Calculator

About the Old vs New Tax Regime Calculator

Enter your income and the deductions you actually claim, and see tax computed under both regimes side by side — so the choice is based on your own numbers, not a rule of thumb.

How it works

The same gross income is run through both regime configurations: the old regime applies your entered deductions (80C, HRA, home loan interest, etc.) before slab tax at higher rates; the new regime applies only the ₹75,000 standard deduction before slab tax at lower rates. Both include the applicable 87A rebate, surcharge, and cess, so the comparison is on final take-home, not just headline rates.

Frequently asked questions

Why did the government make the new regime the default?

The new regime is simpler to administer and closes exemption-related paperwork and avoidance, and for taxpayers who don't use most deductions it results in a lower bill. Since FY 2023-24 it applies automatically unless you actively opt for the old regime when filing.

What deductions only work under the old regime?

HRA exemption, Section 80C (₹1.5L — ELSS, PPF, life insurance, etc.), home loan interest under Section 24(b), and most other Chapter VI-A deductions. The new regime allows only a handful, mainly the standard deduction and employer NPS contributions.

Can I switch regimes every year?

Salaried individuals without business income can choose freely each financial year when filing. Those with business or professional income have a more restricted one-time switch back to the old regime.
