Tax payable (with cess)
Estimate only, based on FY 2026–26 slab rates and Section 87A rebate. Doesn't account for HRA exemptions, capital gains, or surcharge on very high incomes — check with a tax advisor for exact filing figures.
Your gross income is first reduced by the standard deduction (and, under the old regime, any 80C/80D deductions you claim) to arrive at taxable income. That taxable income is then taxed slab by slab — each slice is taxed only at its own rate, not the whole amount at the highest rate.
Your total annual salary or income before deductions.
New regime has lower rates but fewer deductions; old regime lets you claim 80C, 80D, etc.
Estimated tax payable, plus your take-home pay.
The tax formula
Taxable income = gross income − standard deduction − other deductions
Tax is applied slab-wise on taxable income, then a 4% health & education cess is added.
Section 87A gives a full rebate (zero tax) if taxable income is within the rebate limit — ₹12L for the new regime, ₹5L for the old regime.
A worked example
A ₹12,00,000 annual income under the new regime, no extra deductions:
| Gross income | ₹12,00,000 |
| Standard deduction | ₹75,000 |
| Taxable income | ₹11,25,000 |
| Tax before rebate | ₹41,250 |
| Section 87A rebate | − ₹41,250 |
| Final tax payable | ₹0 |
Because taxable income falls at or below ₹12L, the 87A rebate wipes out the tax entirely under the new regime — this is why ₹12.75L gross is often called "tax-free" under the new regime.

The new regime usually wins if you don't have large deductions like home loan interest, 80C investments, or HRA. The old regime can work out cheaper if your combined deductions are substantial — this calculator lets you compare both.
It's a rebate that reduces your tax liability to zero if your taxable income falls within a set limit — ₹12,00,000 under the new regime and ₹5,00,000 under the old regime. Above that limit, you pay tax on the full slab structure.
A 4% health and education cess is included. Surcharge, which applies only above ₹50 lakh income, is not included in this simplified estimate.
Not exactly — employers estimate TDS monthly based on your declared investments and projected income, which can differ slightly from your final tax liability at year-end filing.
