Income Tax Calculator

Your income tax is slab-rate tax on taxable income, minus any rebate, plus surcharge above ₹50 lakh and 4% cess. The new regime is the default: it gives a ₹75,000 standard deduction, and a resident individual with taxable income up to ₹12,00,000 pays nothing. The old regime gives a ₹50,000 standard deduction plus deductions such as 80C. The calculator works out both and shows the cheaper one.

1. The standard deduction, ₹75,000 in the new regime or ₹50,000 in the old, comes off salary and pension under section 16(ia) (section 19 of the 2025 Act), and other income is added.
2. In the old regime only, HRA under section 10(13A), self-occupied home-loan interest under section 24(b) (up to ₹2,00,000) and deductions such as 80C (up to ₹1,50,000), 80CCD(1B) (up to ₹50,000) and 80D also come off.
3. Slab rates apply next: one set for every age in the new regime under section 115BAC (section 202 of the 2025 Act), and three age bands (below 60, 60 to 79, 80 and over) in the old regime.
4. A resident individual gets the rebate under section 87A (section 156 of the 2025 Act): up to ₹60,000 if taxable income is ₹12,00,000 or less in the new regime, with marginal relief just above that, or up to ₹12,500 if it is ₹5,00,000 or less in the old regime.
5. Surcharge, with marginal relief, is 10% above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore, and the old regime adds a 37% band above ₹5 crore.
6. Health and education cess of 4% goes on top of tax plus surcharge, and the regime with the lower total is shown as the better one.

Rahul is 34, a resident individual, and earns a salary of ₹18,00,000 in FY 2026-27, with no other income. For the old regime he has ₹1,50,000 of 80C investments, ₹50,000 of NPS under 80CCD(1B), ₹25,000 of family health insurance under 80D and ₹2,00,000 of home-loan interest on the flat he lives in.

1. New regime: ₹18,00,000 − ₹75,000 standard deduction = ₹17,25,000 taxable income.
2. New regime tax: ₹1,45,000 at slab rates + ₹5,800 cess = ₹1,50,800.
3. Old regime: ₹18,00,000 − ₹50,000 standard deduction − ₹2,00,000 home-loan interest − ₹2,25,000 of 80C, 80CCD(1B) and 80D = ₹13,25,000 taxable income.
4. Old regime tax: ₹2,10,000 at slab rates + ₹8,400 cess = ₹2,18,400.

Rahul pays ₹1,50,800 under the new regime, ₹67,600 less than the ₹2,18,400 he would pay under the old regime.

Yes, for a resident individual. If taxable income is ₹12,00,000 or less, the rebate under section 87A (section 156 of the Income-tax Act 2025), worth up to ₹60,000, cancels the whole tax. With the ₹75,000 standard deduction, a salary of ₹12,75,000 pays no tax.

Nil up to ₹4,00,000, 5% up to ₹8,00,000, 10% up to ₹12,00,000, 15% up to ₹16,00,000, 20% up to ₹20,00,000, 25% up to ₹24,00,000 and 30% above that. The slabs are the same as in FY 2025-26 and apply at every age; the Income-tax Act 2025 sets them in section 202.

₹75,000 under the new regime and ₹50,000 under the old regime, the same as in FY 2025-26. Section 19 of the Income-tax Act 2025 (section 16(ia) of the 1961 Act) allows it, and it applies to salary and pension.

No. The new regime under section 115BAC (section 202 of the Income-tax Act 2025) disallows most deductions and exemptions, so 80C, 80CCD(1B), 80D, 80TTA, 80TTB, self-occupied home-loan interest under section 24(b) and HRA count only in the old regime. The new regime keeps the ₹75,000 standard deduction.

In the new regime, a resident individual's tax before cess cannot exceed the part of taxable income above ₹12,00,000. A salary of ₹13,00,000 gives taxable income of ₹12,25,000, so the tax is ₹25,000 plus 4% cess, or ₹26,000 in all.

For a resident aged 60 to 79: nil up to ₹3,00,000, 5% up to ₹5,00,000, 20% up to ₹10,00,000 and 30% above. From age 80: nil up to ₹5,00,000, 20% up to ₹10,00,000 and 30% above. Non-residents, HUFs, AOPs and BOIs use the below-60 slabs, which are nil only up to ₹2,50,000.
