Income Tax Calculator

How this calculator works

Enter your annual gross income and your age category, plus any deductions you'd claim under the old regime (Section 80C investments, 80D health insurance, HRA exemption, home loan interest, and so on, added together). The calculator applies the correct slabs, standard deduction, Section 87A rebate, and 4% cess for both regimes side by side, so you can see exactly which one results in less tax for your situation.

Why the "right" regime depends on your deductions

The new regime's lower rates and bigger standard deduction make it the better default for most salaried people who don't have significant 80C investments, home loan interest, or HRA to claim. But if your total eligible deductions are large — commonly ₹2–4 lakh or more between 80C, 80D, HRA, and a home loan — the old regime's ability to subtract those from your taxable income often wins out. There's no universally correct choice; it depends entirely on your own numbers, which is exactly what this comparison shows.

A note on accuracy

This calculator covers the standard slabs, standard deduction, Section 87A rebate, and health & education cess for both regimes, including the higher exemption limits for senior (60–80) and super senior (80+) citizens under the old regime. It does not model surcharge on very high incomes, capital gains taxed at special rates, or every possible deduction. Treat it as a solid estimate and starting point for comparing regimes, not a substitute for a tax professional.
