Compare both regimes every year before filing — the cheaper one can change with your income and investments.
The old regime usually wins when your deductions (80C, 80D, HRA, home loan interest) are large.
The new regime usually wins when your deductions are small, thanks to wider slabs and the ₹60,000 rebate up to ₹12 lakh.
Keep Form 16 and your investment proofs ready to justify every deduction you claim.
Cross-check the TDS already deducted against Form 26AS / AIS on the income tax portal.
Treat this as an estimate — confirm your final tax on the official portal or with a tax advisor before filing.
Income tax is a direct tax you pay to the government on the income you earn in a financial year, calculated using slab rates that rise with income.
The old regime has higher rates but lets you claim most deductions and exemptions. The new regime has lower, wider slabs and a bigger rebate but allows very few deductions.
Add up all your income, subtract the deductions allowed under your chosen regime, and the remainder is your taxable income on which slab tax is charged.
A flat deduction for salaried people and pensioners — ₹50,000 (old regime) or ₹75,000 (new regime) for FY 2025-26 — applied automatically when you enter salary income.
A rebate that can reduce tax to zero for lower incomes: up to ₹12,500 (old, taxable income ≤ ₹5L) or up to ₹60,000 (new, taxable income ≤ ₹12L).
A 4% charge added on top of your income tax plus surcharge, funding health and education programmes. It is shown separately in the breakup.
Your final tax divided by your gross income, as a percentage. It is usually well below your top slab rate because lower slabs are taxed less.
Use eligible deductions (80C, 80D, NPS), claim HRA and home-loan interest where applicable, and pick the regime that results in lower tax for your situation.
Capital gains, special-rate income, exact exemptions, surcharge marginal relief, employer payroll rules and the latest rules can all change the final figure.
It is a tool that estimates how much income tax you owe for a financial year based on your income, deductions, age and chosen tax regime — and helps you compare the old and new regimes side by side.
It depends on your deductions. If you claim large deductions (80C, HRA, home loan interest, etc.) the old regime can be cheaper. If your deductions are small, the new regime — with its wider slabs and ₹60,000 rebate up to ₹12 lakh — is usually better. This calculator recommends the lower-tax option for you.
The old regime has higher rates but allows most deductions and exemptions. The new regime has lower, wider slabs and a higher rebate but allows only a few deductions (mainly the standard deduction for salaried people).
Yes. From FY 2023-24 onwards the new tax regime is the default. You can still opt for the old regime when filing if it works out cheaper for you.
It is a rebate that can reduce your tax to zero for lower incomes. Under the old regime it is up to ₹12,500 if taxable income is up to ₹5 lakh. Under the new regime it is up to ₹60,000 if taxable income is up to ₹12 lakh (for FY 2025-26).
A flat deduction available to salaried individuals and pensioners — ₹50,000 under the old regime and ₹75,000 under the new regime for FY 2025-26 — applied automatically here when you enter salary income.
No. Section 80C, 80D, HRA, home loan interest and most other deductions are not allowed under the new regime. Only a limited set (mainly the standard deduction) applies. This calculator does not apply old-regime deductions to the new regime.
Actual tax can differ due to capital gains and other special-rate income, exact exemption amounts, surcharge marginal relief, employer payroll rules, TDS timing and the latest Income Tax Department rules. This tool gives a careful estimate, not a filing.
Yes. Enter your salary income (the standard deduction is applied automatically) plus any other income and deductions to estimate your tax under both regimes.
Yes, for regular business or professional income. Note that the standard deduction applies only to salary income, and presumptive taxation or special-rate items are not modelled here.
Yes. It applies surcharge for incomes above ₹50 lakh (10%/15%/25%, and 37% for the old regime above ₹5 crore) with marginal-relief logic. Very high incomes should still be verified with a professional.
Yes. Health and Education Cess of 4% is applied on income tax plus surcharge and shown separately in the breakup.
It is your final tax payable divided by your gross income, shown as a percentage. It reflects the real share of income that goes to tax, which is usually lower than your top slab rate.
It is your estimated final annual tax divided by 12 — a simple way to see roughly how much tax burden falls on each month.
