About the Income Tax Calculator
India lets most individuals choose between two tax systems each year: the new regime, which has wider, lower slabs but almost no deductions, and the old regime, which has higher rates but lets you claim exemptions like 80C, 80D, HRA and home-loan interest. This calculator computes your tax under both for tax year 2026-27 — the first year of the Income-tax Act, 2025, which replaced "financial year / assessment year" with a single "tax year" — and tells you which is cheaper.
Under the new regime, income up to ₹4 lakh is nil, then 5%, 10%, 15%, 20%, 25% and 30% bands apply through ₹24 lakh and above, with a ₹75,000 standard deduction for salaried people and a rebate (section 156, formerly 87A) that makes tax zero for taxable income up to ₹12 lakh, with marginal relief just above. The old regime uses the ₹2.5L / 5% / 20% / 30% slabs, a ₹50,000 standard deduction, an 87A rebate up to ₹5 lakh, and lets you subtract your total deductions. A 4% health & education cess is added to both. Enter your gross income and old-regime deductions to compare side by side.
This is an estimate only. It models surcharge and its marginal relief, but not capital-gains or other special-rate income, or every special deduction, and tax law changes. Always confirm with an official source or a tax professional before filing. Nothing you enter leaves your browser.

Tips for the best results
- It's an estimate. This is a planning tool, not a filing statement — cess, surcharge on high incomes and special-rate income can shift the final figure.
- The old regime rewards deductions. It usually only wins if you actually claim meaningful 80C/80D/HRA amounts; otherwise the new regime is often simpler and cheaper.
- Include the standard deduction. If you're salaried, make sure that box is ticked so both regimes are compared on equal footing.
