Calculator
Income Tax Calculator
This calculator estimates your income tax for FY 2025-26 (Assessment Year 2026-27) under either the new or the old regime. It applies the relevant slab rates, the standard deduction for salaried taxpayers, the Section 87A rebate, and the 4% health and education cess. Enter your gross annual income — and, for the old regime, your total deductions like 80C and 80D — to see your estimated tax, effective tax rate, and annual take-home, so you can choose the regime that costs you less.
Total salary / income before any deductions.

Estimate for FY 2025-26 (AY 2026-27), salaried resident individual below 60. Includes standard deduction, Section 87A rebate and 4% cess. Excludes surcharge (applies above ₹50 lakh), marginal relief near rebate thresholds, and special-rate income (capital gains, lottery). Verify with a tax professional or the official e-filing portal before filing.
What your result means
- Your effective rate (tax ÷ income) is always lower than your slab rate, because only the income inside each slab is taxed at that slab’s rate.
- The new regime is simpler with lower slab rates but almost no deductions; the old regime can win if you claim large 80C, 80D, HRA, and home-loan benefits — compare both.
- A 4% health-and-education cess applies on top of the tax, and a surcharge kicks in at higher incomes.
How to use this calculator
- Enter your gross annual income before any deductions.
- Pick the new regime first — it is the default and needs no deductions.
- Switch to the old regime and enter your total deductions (80C, 80D, HRA, home-loan interest) to compare.
- Compare “total tax payable” between the two regimes and choose the lower one.
- Use the effective tax rate to understand your real tax burden, not just the slab you fall in.
The formula
Taxable income = Gross − Standard deduction (₹75,000 new / ₹50,000 old) − eligible deductions (old regime only). Tax = sum of slab rates applied band-by-band. If the Section 87A rebate applies (taxable ≤ ₹12L new / ≤ ₹5L old), tax becomes nil. Total = Tax + 4% cess.
Worked example
Gross salary ₹15,00,000, new regime: taxable = ₹15,00,000 − ₹75,000 = ₹14,25,000. Slab tax = 0 (to 4L) + ₹20,000 (4–8L) + ₹40,000 (8–12L) + ₹33,750 (12–14.25L) = ₹93,750. Cess 4% = ₹3,750. Total ≈ ₹97,500. Under the old regime with ₹2,00,000 deductions, taxable = ₹12,50,000, slab tax = ₹1,87,500, cess ₹7,500, total ≈ ₹1,95,000 — so the new regime is cheaper here by nearly ₹98,000.
When to use it
- Deciding between the new and old tax regime for the year.
- Estimating tax before submitting your investment declaration to your employer.
- Checking how much extra 80C/80D deductions actually save under the old regime.
- Planning take-home pay and advance-tax instalments.
