The Union Budget 2026 left the slabs unchanged, so FY 2025-26 and FY 2026-27 are taxed identically.
New regime — default
Applies unless you opt out. Standard deduction ₹75,000 for salary and pension.
| Total income | Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Section 87A rebate up to ₹60,000 makes total income up to ₹12,00,000 tax-free — about ₹12,75,000 of gross salary once the standard deduction is applied. Age makes no difference to the new-regime slabs.
Old regime — opt in
Keeps 80C, 80D, HRA and home-loan interest. Standard deduction ₹50,000.
| Total income | Below 60 | 60–80 | 80+ |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | Nil | Nil |
| ₹2,50,001 – ₹3,00,000 | 5% | Nil | Nil |
| ₹3,00,001 – ₹5,00,000 | 5% | 5% | Nil |
| ₹5,00,001 – ₹10,00,000 | 20% | 20% | 20% |
| Above ₹10,00,000 | 30% | 30% | 30% |
Section 87A rebate up to ₹12,500 makes total income up to ₹5,00,000 tax-free. Senior citizens claim 80TTB (₹50,000) instead of 80TTA (₹10,000).
Surcharge and cess
Charged on top of the slab tax once income crosses ₹50 lakh. Marginal relief is applied automatically.
| Total income | Old regime | New regime |
|---|---|---|
| ₹50 lakh – ₹1 crore | 10% | 10% |
| ₹1 crore – ₹2 crore | 15% | 15% |
| ₹2 crore – ₹5 crore | 25% | 25% |
| Above ₹5 crore | 37% | 25% — capped |
Health & education cess of 4% applies to tax plus surcharge under both regimes.
This calculator covers salary, pension, interest, rental and other ordinary income for a resident individual. It does not compute capital gains (which are taxed at special rates with their own 15% surcharge cap), clubbing, relief under Sections 89, 90 or 91, AMT, or the tax on firms, LLPs and companies. Rates are those in force for FY 2025-26 and FY 2026-27 and are given for general guidance — please confirm your final figures with your CA or on the Income Tax Department portal before filing.
Income tax, answered
Is income up to ₹12 lakh really tax free?
Under the new regime, yes. A Section 87A rebate of up to ₹60,000 cancels the tax on total income up to ₹12,00,000. For a salaried person the ₹75,000 standard deduction lifts that to roughly ₹12,75,000 of gross salary. Cross ₹12,00,000 and the rebate stops — but marginal relief caps the tax so it can never exceed the amount by which you crossed the line.
Which regime should I pick?
It comes down to how much you genuinely claim. The new regime gives wider slabs and a larger standard deduction but disallows 80C, 80D, HRA and self-occupied home-loan interest. The old regime is narrower but keeps them. If your total deductions are large — a full 80C, health insurance, HRA and a home loan — the old regime often still wins. This page computes both, so you don't have to guess.
Can I switch regimes each year?
Salaried taxpayers without business income may choose afresh every year when filing. Taxpayers with business or professional income can opt out of the new regime only once, and switching back is restricted — so take that decision with your CA.
What is marginal relief?
It stops a small rise in income from causing a disproportionate jump in tax. It applies in two places: just above ₹12,00,000 in the new regime, where the 87A rebate falls away, and just above each surcharge threshold (₹50 lakh, ₹1 crore, ₹2 crore, ₹5 crore). Both are handled automatically here.
Does this send my salary details anywhere?
No. The calculation is plain JavaScript running in your own browser. Nothing is uploaded, logged or stored — you can disconnect from the internet and it will still work.
Do the slabs change for FY 2026-27?
No. The Union Budget 2026 announced no change to the slabs or the basic exemption limits, so FY 2026-27 (AY 2027-28) is taxed on the same rates as FY 2025-26.
