Income tax calculator FY 2026-27

Calculate your income tax under India's new and old tax regimes for FY 2026–27. See a slab-wise breakdown for both regimes side-by-side.

How is Income Tax calculated in India?

India's income tax system for FY 2026-27 (AY 2027-28) offers two regimes. The new regime — the default since 2023 — has lower slab rates but allows only the standard deduction (₹75,000 for salaried) and a few specific exemptions. The old regime has higher rates but lets you claim 80C, 80D, HRA, home-loan interest, LTA, and many other deductions. Budget 2026 left all slabs, rebate thresholds, and surcharge tiers unchanged — the rate structure carries forward from FY 2025-26.

A 4% health and education cess applies on top of the calculated tax in both regimes. A surcharge kicks in on taxable income above ₹50 lakh, stepping up at ₹1 crore and ₹2 crore. Under the new regime, the maximum surcharge is capped at 25%; the old regime can go up to 37% above ₹5 crore.

"We are not compelling anybody. Those who want to remain in the old regime can still remain there. But the new one is attractive because it gives a greater rebate."

How the calculation works

The calculator applies slab rates on taxable income (gross minus deductions), then: adds surcharge if taxable income exceeds ₹50 lakh, subtracts 87A rebate if eligible, and finally adds 4% health & education cess on (tax + surcharge). Rebate marginal relief ensures that crossing the ₹12 lakh threshold in the new regime doesn't suddenly jump your tax by more than the excess.

Important caps and defaults

Standard deduction is ₹75,000 in the new regime and ₹50,000 in the old regime (salaried only). Under 87A, the full rebate applies to taxable income up to ₹12 lakh in the new regime and ₹5 lakh in the old regime. Section caps: 80C — ₹1.5 lakh; 80D — ₹1 lakh (self + senior parents combined); self-occupied home-loan interest under 24(b) — ₹2 lakh. HRA exemption has no statutory rupee cap, but it can't exceed 50% of gross income (the worst case: metro city with basic salary = gross).

Common Uses

FAQ

Which regime should I pick — new or old?

For most salaried taxpayers with limited investments, the new regime is cheaper — its ₹75,000 standard deduction and full rebate up to ₹12L taxable income means zero tax on salary up to ₹12.75L. The old regime only wins if your 80C, 80D, HRA, and home-loan interest deductions add up to a large amount (typically ₹3L+).

What is the tax-free salary limit in FY 2026-27?

Under the new regime in FY 2026-27, salaried individuals pay zero tax on income up to ₹12.75 lakh thanks to the ₹75,000 standard deduction plus full 87A rebate on taxable income up to ₹12 lakh. Non-salaried individuals get zero tax up to ₹12 lakh. These thresholds are unchanged from FY 2025-26.

What's the difference between cess and surcharge?

Cess is charged at 4% on (tax + surcharge) and funds health and education programs. Surcharge is an extra percentage on the tax amount itself, applied when taxable income crosses ₹50 lakh (10%), ₹1 crore (15%), ₹2 crore (25%), or ₹5 crore (37% — old regime only). Cess applies to everyone; surcharge only at higher incomes.

Can I switch regimes when filing?

Yes. Even if your employer deducted TDS based on a specific regime, you can pick the other regime when filing your return. Non-salaried taxpayers can switch between regimes year to year; salaried individuals with business income have more restrictions after opting out of the new regime once.
