Is the Income Tax Calculator really free?
Yes. There is no paywall, no trial, no watermark, and no usage cap. Open Income Tax Calculator and use it as often as you like.
Does the tool upload my income details?
No. Everything runs locally in your browser. Your income and deduction inputs never leave your device, so nothing is leaked or stored.

Section 87A limits your income tax (before cess) to zero when your taxable income is within the prescribed threshold for the financial year. The calculator applies it automatically to both regimes.
