Income Tax Calculator
Compare your income tax under the old and new regimes for FY 2025-26 (AY 2026-27), with standard deduction, 87A rebate and cess.
About this calculator
This free income tax calculator estimates your tax for FY 2025-26 (AY 2026-27) and shows the old and new regimes side by side so you can see which one costs you less. It applies the standard deduction, the section 87A rebate and the 4% health and education cess.
New regime vs old regime
The new regime has lower slab rates and a ₹75,000 standard deduction, but you give up most exemptions. The old regime keeps higher rates but lets you reduce taxable income with deductions like 80C (up to ₹1.5 lakh), 80D, HRA and home-loan interest. Enter your total old- regime deductions to compare fairly.
Worked example
On a ₹12,00,000 salary with ₹1,50,000 of deductions: the new regime works out to ₹0 (taxable income up to ₹12 lakh is fully rebated), while the old regime is about ₹1,17,000 — so the new regime wins here.

Why use this income tax calculator
Old vs new, side by side
It computes your liability under both regimes at once and tells you which one is cheaper for your exact income and deductions — the decision most people get wrong.
Rebate and cess built in
The section 87A rebate and the 4% health & education cess are applied automatically, so the figure matches your actual payable tax, not just the slab total.
Honest about its limits
It flags what it does not cover — surcharge above ₹50 lakh, marginal relief, senior-citizen slabs — so you know when to consult a professional.
Common use cases
- Decide whether to opt for the old or new regime this year
- See how much extra 80C and 80D investments actually save you
- Estimate the TDS your employer will deduct from salary
- Plan advance-tax instalments from a freelance or business income

The new regime has lower rates but almost no deductions; the old regime has higher rates but lets you claim 80C, 80D, HRA, home-loan interest and more. Enter your deductions and the calculator shows which comes out lower for you.
It makes tax nil for lower incomes — up to ₹12 lakh taxable income under the new regime (FY 2025-26) and up to ₹5 lakh under the old regime.
It adds the 4% health and education cess. It does not apply the surcharge on incomes above ₹50 lakh, marginal relief, or senior-citizen slabs, so treat it as an estimate.
