How the Income Tax Calculator Works
What Is the New Tax Regime?
the new tax regime is set out in section 115bac of the income-tax act, 1961 (and section 202 of the new income-tax act, 2025). it offers wider, lower slabs but removes most deductions and exemptions. it is now the default regime, and tends to suit taxpayers without elaborate tax-saving investments.
New Regime Slab Rates — FY 2025-26 (ay 2026-27)
| income (₹) | tax rate |
|---|---|
| up to 4 lakh | nil |
| 4–8 lakh | 5% |
| 8–12 lakh | 10% |
| 12–16 lakh | 15% |
| 16–20 lakh | 20% |
| 20–24 lakh | 25% |
| above 24 lakh | 30% |
Zero Tax on Income Up to ₹12 Lakh — How It Works
under the new regime, the section 87a rebate makes tax nil for normal-slab income up to ₹12 lakh — and ₹12.75 lakh for salaried taxpayers after the ₹75,000 standard deduction. the rebate does not apply to special-rate income like capital gains or crypto. a worked example:
| particulars | amount (₹) |
|---|---|
| gross salary | 12,75,000 |
| less: standard deduction | 75,000 |
| taxable salary | 12,00,000 |
| tax (0–4L nil; 4–8L = 20,000; 8–12L = 40,000) | 60,000 |
| less: §87a rebate | 60,000 |
| net tax payable | nil |
Old Regime Slab Rates — FY 2025-26
the old regime keeps its long-standing slabs and a wide range of deductions.
| income (₹) | tax rate |
|---|---|
| up to 2.5 lakh | nil |
| 2.5–5 lakh | 5% |
| 5–10 lakh | 20% |
| above 10 lakh | 30% |
Old Regime — Senior & Super-senior Citizens
resident seniors (60–80) and super-seniors (80+) get a higher basic exemption under the old regime.
| age | basic exemption |
|---|---|
| below 60 | ₹2.5 lakh |
| 60–80 (senior) | ₹3 lakh |
| 80+ (super senior) | ₹5 lakh |
Deductions: Old vs New Regime
| benefit | old regime | new regime |
|---|---|---|
| §87a rebate | ₹12,500 (up to ₹5L) | ₹60,000 (up to ₹12L) |
| standard deduction | ₹50,000 | ₹75,000 |
| section 80c | allowed | not allowed |
