About the Income Tax Calculator
This calculator estimates your income tax for FY 2025-26 (and FY 2024-25) under both the New and Old regimes. Enter your income, choose a regime, and it works out your taxable income, the tax on each slab, any surcharge, and the 4% health & education cess, including the standard deduction and the Section 87A rebate that makes income up to ₹12 lakh tax-free in the New regime.
How to use it
- Select the financial year and your tax regime (New or Old).
- Enter your gross annual income before deductions.
- For the Old regime, add deductions such as 80C, 80D, NPS and home-loan interest.
- Read your taxable income, tax, surcharge and cess in the result panel instantly.
Use it before filing your ITR, at appraisal time, or while planning tax-saving investments, to know exactly what you'll owe. Because the maths runs entirely in your browser, your salary and income figures are never uploaded to any server, so it's completely private.
Frequently asked questions
Which tax regime should I choose?
If you claim large deductions (80C, 80D, home-loan interest, HRA), the Old regime can be cheaper; otherwise the New regime usually wins thanks to its higher standard deduction and 87A rebate. Use our Old vs New comparison tool to see the exact difference for your income.
Does it include the standard deduction?
Yes. The standard deduction (₹75,000 in the New regime, ₹50,000 in the Old) is applied automatically before tax is calculated.
Are surcharge and cess included?
Yes. The 4% health and education cess is always added, and surcharge is applied for incomes above ₹50 lakh. Surcharge is shown without marginal relief, so verify large figures on the official income-tax portal.
Is my income data private?
Completely. The calculation happens in your browser using JavaScript; nothing you type is sent to or stored on any server.
