Enter your annual income and old-regime deductions to see income tax under both regimes side by side for FY 2025-26 (FY 2024-25 also selectable), with the standard deduction, 87A rebate, marginal relief, taxable income, effective rate and which regime saves you more.
Last updated 5 September 2026
80C, 80D, home loan interest, HRA exemption etc. combined — ignored under the new regime.
For FY 2025-26, the new regime saves you ₹1,40,400 a year.
New regime tax is nil here — the Section 87A rebate covers taxable income up to ₹12,00,000.

FY 2025-26 is the default; switch to FY 2024-25 if you are reconciling last year's return.
Gross income before any deduction.
Combine 80C, 80D, home loan interest, HRA exemption and any other old-regime-only deductions into one figure. Then compare the two regimes side by side.
Tax = min(Σ(slab band × slab rate), marginal relief) − 87A rebate, then × 1.04 for cess
Surcharge on incomes above ₹50 lakh is not modelled.
New regime: ₹12,75,000 − ₹75,000 standard deduction = ₹12,00,000 taxable, which is exactly at the FY 2025-26 Section 87A rebate limit, so tax is nil. Old regime: ₹12,75,000 − ₹50,000 − ₹1,50,000 = ₹10,75,000 taxable → ₹12,500 (5% of ₹2.5L) + ₹1,00,000 (20% of ₹5L) + ₹22,500 (30% of ₹75,000) = ₹1,35,000, plus 4% cess ≈ ₹1,40,400.
The Budget of February 2025 made the new regime the clear default for most salaried people: with the ₹4,00,000 tax-free slab, a ₹75,000 standard deduction and the Section 87A rebate extended to ₹12,00,000 of taxable income, a salaried person earning up to about ₹12,75,000 pays no tax at all under the new regime.
The old regime can still win if your genuine deductions are large — a full ₹1.5 lakh under 80C, ₹2 lakh of home loan interest, 80D health premiums and a substantial HRA exemption can together exceed ₹4–5 lakh, at which point the old regime's outcome may be lower despite its higher rates. Run both here rather than assuming.
This single input is meant to combine everything the old regime allows that the new regime doesn't: Section 80C investments (up to ₹1.5 lakh — PF, ELSS, life insurance premiums, etc.), 80D health insurance premiums, home loan interest under Section 24(b), and your HRA exemption if you pay rent.
Work out each of these separately — this site's HRA Exemption Calculator handles the HRA piece — and add them together before entering the total here, rather than guessing a round number.
Without it, someone with ₹12,10,000 taxable under the new regime would jump from ₹0 tax to over ₹61,000 — far more than the ₹10,000 of extra income. Marginal relief caps the tax in that band at the amount of income above ₹12 lakh, tapering back to normal slab tax by about ₹12,70,000. The calculator applies it automatically.
FY 2025-26 (AY 2026-27) by default, with the slabs from the February 2025 Budget, and FY 2024-25 (AY 2025-26) as a selectable option. When a future Budget changes the slabs, the calculator is updated.
Under the new regime for FY 2025-26, taxable income up to ₹12,00,000 attracts no tax thanks to the enhanced Section 87A rebate — with the ₹75,000 standard deduction, that is a salary near ₹12,75,000. It does not apply to the old regime or to capital gains.
Salaried individuals can choose either regime each financial year. Those with business income have restrictions on switching back after opting out once.
No — HRA exemption is a separate old-regime deduction. Use the HRA Exemption Calculator to work that out, then add it to "old regime deductions" here.
