How the Income Tax Calculator works
The calculator runs both regimes from the same income. It subtracts the standard deduction (and, under the old regime, the deductions you enter), applies the slab rates, takes off the section 87A rebate where you qualify with marginal relief just above the limit, then adds any surcharge and the 4% health and education cess.
It is an estimate for a resident individual. Capital gains and other income taxed at special rates are not included, so treat it as a comparison of the two regimes and file using the figures in Form 16 and on the income tax portal.
Often used with: PPF Calculator, FD Calculator, GST Calculator
Income Tax Calculator: questions people ask
Is income up to ₹12 lakh tax-free?
Under the new regime, yes for salaried people, thanks to the ₹75,000 standard deduction and the 87A rebate; up to ₹12.75 lakh of salary pays no tax.
Which regime is better?
The old regime only wins if your deductions (80C, HRA, home-loan interest) are large.
Is my data uploaded when I use the Income Tax Calculator?
No. The Income Tax Calculator runs entirely in your web browser, so your text and numbers stay on your device and work even on a slow connection.
Does the Income Tax Calculator work on iPhone, Android and Mac?
Yes. The Income Tax Calculator runs in any modern browser (Safari, Chrome, Edge or Firefox) on iPhone, iPad, Android phones, Mac, Windows and Chromebook. There is no app to install.
Is the Income Tax Calculator free?
Yes. The Income Tax Calculator is free with no signup, no watermark and no daily limit.
Which year do these slabs cover?
FY 2026-27. Budget 2026 did not change the slabs. The new regime is still the default: nil up to ₹4 lakh, then 5%, 10%, 15%, 20%, 25% and 30% above ₹24 lakh. A resident with taxable income up to ₹12 lakh pays no tax because of the section 87A rebate, with marginal relief just above that.
What is included in the estimate?
Salary standard deduction (₹75,000 in the new regime, ₹50,000 in the old), optional employer NPS capped at 14% of basic in the new regime and 10% in the old, and in the old regime section 80C up to ₹1.5 lakh, 80D up to ₹1 lakh, and other deductions you type. Surcharge and 4% health and education cess are added. Capital gains, crypto, and perquisites are not.
Can I file my return from this number?
No. Use it to compare regimes and plan TDS. The legal return depends on the Income Tax Act, 2025, your Form 16, and incomes this page does not ask for.
