How this calculator works
Enter your income and deductions once. The calculator works out tax under both regimes side by side — slab tax, the rebate (old 87A, now 156) with marginal relief, surcharge with marginal relief, and 4% cess — and shows which regime costs less.
- New regime: ₹75,000 standard deduction for salaried people, employer NPS up to 14% of salary; most other deductions are not allowed.
- Old regime: ₹50,000 standard deduction, HRA, 80C, 80D, 80CCD(1B), home-loan interest and more.
- FY 2024-25 uses that year's slabs (3–7–10–12–15 lakh) and the ₹7 lakh rebate limit; later years use the 4–8–12–16–20–24 lakh slabs and ₹12 lakh.
Worked example
Salary ₹13,00,000 with ₹1.5 lakh in 80C and ₹25,000 in 80D: new regime taxable income ₹12,25,000 → tax ₹26,000 after marginal relief; old regime taxable ₹10,75,000 → ₹1,40,400. The new regime saves ₹1,14,400.
Questions about this calculator
Yes — 10%, 15%, 25% (and 37% in the old regime) with marginal relief at each threshold, plus 4% cess.
₹12,75,000 − ₹75,000 standard deduction = ₹12,00,000 taxable; the rebate under 87A (now 156) wipes out tax up to that level in the new regime.
No. Special-rate income such as STCG on shares is taxed separately — use the Capital Gains calculator.
