What does the Income Tax Calculator do?
The Income Tax Calculator computes your tax liability for FY 2026-27 under both the new and old tax regimes. It applies the Section 87A rebate (which limits income tax before cess) and the 4% health and education cess, then presents a side-by-side comparison so you can see which regime saves you more.
Common uses
- Annual tax planning — estimate your tax bill before the financial year ends so you can adjust investments or deductions
- Regime comparison — decide whether the new regime (lower rates, fewer deductions) or the old regime (HRA, 80C, 80D deductions) is better for your salary
- Freelancer tax check — calculate advance tax obligations on self-employment or freelance income
- Pre-filing review — verify your numbers before filing the ITR so there are no surprises
Key features
- New vs old regime — enter your income once and see the tax under both regimes instantly
- 87A rebate and cess — the 87A rebate is applied to income tax before the 4% health and education cess is added, exactly as the IT Act prescribes
- Side-by-side compare — a clear table showing taxable income, deductions, tax, rebate, cess, and final liability under each regime
How it works
Enter your gross income and applicable deductions (such as standard deduction, 80C, and 80D). The tool computes taxable income under both regimes using the FY 2026-27 slab rates. If your total income tax before cess is within the 87A rebate limit, the rebate is applied automatically. The 4% health and education cess is then added to give you the final tax payable. Because everything runs in your browser, results appear instantly.
Verdict
The Income Tax Calculator gives you a clear FY 2026-27 regime comparison with the 87A rebate and cess applied correctly — free, private, and instant.
