From gross salary to final tax payable — the complete calculation process with real numbers. Both Old and New Regime covered with a worked example.
Indian income tax follows a fixed sequence. Here's the exact order — skip a step and you'll get the wrong number:
| Step | What You Do |
|---|---|
| Step 1 | Add all income sources → Gross Total Income |
| Step 2 | Subtract standard deduction + eligible deductions → Taxable Income |
| Step 3 | Apply slab rates to taxable income → Base Tax |
| Step 4 | Apply Section 87A rebate if eligible → Tax After Rebate |
| Step 5 | Add surcharge if total income > ₹50L → Tax + Surcharge |
| Step 6 | Add 4% cess on (tax + surcharge) → Final Tax Payable |

New Regime saves ₹1,44,300 at ₹14L salary without any investments. The Old Regime needs over ₹4 lakh in combined deductions to come close. For most salaried people without home loan interest or large HRA, the New Regime wins clearly at this income level.
Tax is calculated on income from all sources — salary, FD interest, rent received, freelance income. Many people forget to add bank interest and rental income, then face a surprise during ITR filing. Always total all income before assuming you're in the zero-tax zone.
If your taxable income is ₹12L or below, the 87A rebate makes tax ₹0. Cross ₹12L by ₹1 and you owe ~₹83,200. This is why keeping taxable income at or below ₹12L is a major planning priority for salaried Indians in FY 2025-26. Check our Tax Calculator to see your exact position.
