About Income Tax Calculator — Free Online Calculator
Income Tax Calculator estimates tax on an annual income under India's new regime, showing taxable income after the standard deduction, the slab tax, the cess and the effective rate. It is a planning estimate, not a computed return.
One income figure goes in. The page subtracts a 75,000 standard deduction, runs the remainder through a fixed slab table — nil up to 3,00,000, then 5%, 10%, 15%, 20% and 30% — writes the tax down to zero if taxable income is 7,00,000 or less under the section 87A rebate, and adds 4% health and education cess. Those slabs and that rebate threshold are written into the page rather than looked up, so they belong to the year the table was written for and will not match a later Budget. The old regime is not calculated at all, and neither are 80C, 80D, HRA, capital gains, or the surcharge that applies above 50 lakh.
Your income never leaves the browser: not sent to a server, not stored, and not attached to anything that could identify you.
Getting a rough new-regime figure before filing, seeing where the 87A rebate stops and tax begins, understanding what the 4% cess adds on top, and sanity-checking a number a payroll portal has shown.
