Technical notes
Income Tax Calculator (India) applies the Indian income-tax slabs for the regime you pick, adding cess to estimate the tax payable; verify against the current Finance Act.
Tax slabs, rates and deductions change each year, so confirm against the current Finance Act before relying on this.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
Worked example
Under a simple slab where income up to 250,000 is nil, 250,001–500,000 at 5% and 500,001–1,000,000 at 20%, a 700,000 income owes 12,500 + 40,000 = 52,500 before cess/rebates.
FAQ
Which regime should I pick in this income tax calculator?
Enter your income under both the new and old regimes to compare. The new regime has lower rates but fewer deductions; the old regime can win if you claim large deductions such as 80C, HRA, and home-loan interest.
Does the Income Tax Calculator send my data to a server?
No. The Income Tax Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Does it include the Section 87A rebate?
Yes. Under the new regime tax is nil when taxable income is 12,00,000 or less, and under the old regime when taxable income is 5,00,000 or less; the 4% cess is added on any tax that remains.
Why does my figure differ from a payslip TDS estimate?
Payroll TDS spreads tax across the year and may use declared investments and perks. This is an annual estimate on the figures you enter and does not model surcharge on very high incomes.
