Free income tax calculator · FY 2025-26
Enter your salary and other income, your age group and your old-regime deductions — and get your tax under both regimes side by side, with the working, the slab-by-slab breakup and which regime saves you more.
An estimate for FY 2025-26 (AY 2026-27), not tax advice. This tool estimates your tax for FY 2025-26 (AY 2026-27) from the rates in force under the Finance Act 2025 — it is not tax or financial advice. Rates change with every Budget, and your real return depends on your full income, including capital gains and other special-rate income, which this calculator does not cover. Check the Income Tax Department portal or ask a chartered accountant before you file.
Example figures are filled in. Replace them with your own numbers.
New regime: ₹15,00,000 gross − ₹75,000 standard deduction = ₹14,25,000 taxable. Slab tax ₹93,750 plus 4% cess ₹3,750 = ₹97,500.
Old regime: ₹15,00,000 gross − ₹50,000 standard deduction − ₹0 deductions = ₹14,50,000 taxable. Slab tax ₹2,47,500 plus 4% cess ₹9,900 = ₹2,57,400.
Deductions apply to the old regime only. The new regime ignores 80C, 80D, HRA, home-loan interest and NPS — it keeps only the ₹75,000 standard deduction.
This is an estimate for FY 2025-26 (AY 2026-27) on income taxed at normal slab rates. Capital gains and other special-rate income, house-property losses and the employer's NPS contribution are not covered, and the final tax on a return is rounded to the nearest ₹10 under Section 288 — so your filed figure can differ by a few rupees.

Side by side
Comparison for ₹15,00,000 gross income, age below 60. New regime: taxable ₹14,25,000, tax ₹97,500 (6.5% of gross). Old regime: taxable ₹14,50,000, tax ₹2,57,400 (17.16% of gross). The new regime saves you ₹1,59,900.
| Figure | New regime | Old regime |
|---|---|---|
| Gross income | ₹15,00,000 | ₹15,00,000 |
| Standard deduction | − ₹75,000 | − ₹50,000 |
| Old-regime deductions | — (not allowed) | − ₹0 |
| Taxable income | ₹14,25,000 | ₹14,50,000 |
| Slab tax | ₹93,750 | ₹2,47,500 |
| Section 87A rebate | ₹0 | ₹0 |
| Marginal relief | ₹0 | — (none in the old regime) |
| Surcharge | ₹0 | ₹0 |
| Health & education cess (4%) | ₹3,750 | ₹9,900 |
| Total tax payable | ₹97,500 | ₹2,57,400 |
Slab by slab
Each slab taxes only the income inside its own band. The new regime taxes ₹14,25,000; the old regime taxes ₹14,50,000.
| Income band | Rate | Income in band | Tax |
|---|---|---|---|
| Up to ₹4,00,000 | Nil | ₹4,00,000 | ₹0 |
| ₹4,00,001 – ₹8,00,000 | 5% | ₹4,00,000 | ₹20,000 |
| ₹8,00,001 – ₹12,00,000 | 10% | ₹4,00,000 | ₹40,000 |
| ₹12,00,001 – ₹16,00,000 | 15% | ₹2,25,000 | ₹33,750 |
New-regime slab tax: ₹93,750, plus 4% cess ₹3,750 = ₹97,500.
| Income band | Rate | Income in band | Tax |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | ₹2,50,000 | ₹0 |
| ₹2,50,001 – ₹5,00,000 | 5% | ₹2,50,000 | ₹12,500 |
| ₹5,00,001 – ₹10,00,000 | 20% | ₹5,00,000 | ₹1,00,000 |
| Above ₹10,00,000 | 30% | ₹4,50,000 | ₹1,35,000 |
Old-regime slab tax: ₹2,47,500, plus 4% cess ₹9,900 = ₹2,57,400.
Understand the result
India taxes salary and other income in slabs — a higher rate applies only to the income inside each band, never to the whole amount — and since FY 2023-24 you can choose between two regimes: the new regime, with lower rates and almost no deductions, and the old regime, with higher rates but the full set of deductions. This calculator works out your tax under both regimes from the same figures, so you can see which one actually costs less for you.
The new regime is the default since FY 2023-24. Its slabs start at ₹4 lakh instead of ₹2.5 lakh, and the Section 87A rebate makes taxable income up to ₹12 lakh tax-free — but 80C, 80D, HRA and home-loan interest are all gone.
The old regime keeps every deduction — 80C, 80D, HRA, home-loan interest, NPS — and a higher exemption for senior citizens. It only wins when those deductions are large enough to outweigh the higher rates.
This calculator runs your figures through both regimes and shows the saving. On ₹15,00,000 of salary with no deductions the new regime saves ₹1,59,900; with ₹10,00,000 of deductions on ₹25,00,000 the old regime saves ₹62,400.
How it works
Enter your income first — the deductions are already filled in with the usual example — then compare the two totals and read the working for each.
Your gross annual salary and any other income — interest, rent, freelance work. The calculator adds them up; the standard deduction comes off the salary part only.
Below 60, 60–80, or above 80. It changes only the old regime: senior citizens get a ₹3 lakh exemption and super-senior citizens ₹5 lakh, instead of ₹2.5 lakh.
Section 80C, health insurance under 80D, HRA exemption, home-loan interest and NPS — each capped at its legal limit. They count only under the old regime.
The calculator shows both totals, the saving, and which regime wins — with the slab-by-slab working for each, so you can check every rupee.
The calculation, explained
Each regime starts from your gross income, takes off its standard deduction (₹75,000 new, ₹50,000 old — salary only) and, for the old regime, your capped deductions, then taxes the rest slab by slab. The new regime then applies the Section 87A rebate (up to ₹60,000, taxable income up to ₹12,00,000) with marginal relief just above that limit; the old regime applies its ₹12,500 rebate up to ₹5,00,000. Surcharge applies above ₹50 lakh of taxable income, and 4% health and education cess is added on the tax plus surcharge.
Worked examples
One example for each everyday case. Select any example to load it into the calculator and check the working for yourself.
On ₹15,00,000 of salary the new regime taxes ₹14,25,000 (after the ₹75,000 standard deduction) at ₹97,500, while the old regime taxes ₹14,50,000 at ₹2,57,400 — the new regime saves ₹1,59,900.
New regime ₹97,500 · Old regime ₹2,57,400 · New saves ₹1,59,900
The ₹75,000 standard deduction brings taxable income to exactly ₹12,00,000, and the Section 87A rebate of ₹60,000 cancels the ₹60,000 slab tax — total tax ₹0. The old regime on the same salary charges ₹1,87,200.
New regime ₹0 · Old regime ₹1,87,200 · New saves ₹1,87,200
Taxable income is ₹12,50,000, where the slab tax would be ₹67,500 — but marginal relief caps it at the ₹50,000 by which income exceeds ₹12,00,000, so with 4% cess the total is ₹52,000, not ₹70,200.
New regime ₹52,000 · Old regime ₹2,02,800 · New saves ₹1,50,800
With ₹10,00,000 of deductions the old regime taxes ₹14,50,000 at ₹2,57,400, while the new regime taxes ₹24,25,000 at ₹3,19,800 — the old regime saves ₹62,400. Big deductions are the one case where the old regime still wins.
New regime ₹3,19,800 · Old regime ₹2,57,400 · Old saves ₹62,400
Tax rules at a glance
The figures that decide your tax for FY 2025-26: the rebate limits, the standard deductions, the deduction caps and the surcharge bands. All of them come from the Finance Act 2025 and the Income-tax Act.
| Figure | Rule | What it means |
|---|---|---|
| ₹12,75,000 | Zero tax under the new regime (salaried) | A salary of ₹12,75,000 minus the ₹75,000 standard deduction is ₹12,00,000 of taxable income, and the Section 87A rebate of up to ₹60,000 cancels the tax entirely. |
| ₹60,000 | Section 87A rebate, new regime | Resident individuals with taxable income up to ₹12,00,000 get a rebate of up to ₹60,000. Just above ₹12,00,000, marginal relief caps the tax at the amount by which income exceeds ₹12,00,000. |
| ₹12,500 | Section 87A rebate, old regime | Resident individuals with taxable income up to ₹5,00,000 get a rebate of up to ₹12,500. There is no marginal relief in the old regime. |
| ₹75,000 / ₹50,000 | Standard deduction on salary | ₹75,000 under the new regime and ₹50,000 under the old regime, taken off salary income only — other income gets no standard deduction. |
| ₹1,50,000 | Section 80C cap (old regime only) | Investments and expenses under 80C, 80CCC and 80CCD(1) together are capped at ₹1,50,000 a year. NPS under 80CCD(1B) adds up to ₹50,000 more. |
| ₹25,000 / ₹50,000 | Section 80D cap (old regime only) | Health insurance premium for self, spouse and children: up to ₹25,000, or ₹50,000 if you are a senior citizen. Premiums for parents are a separate claim — this calculator does not include them. |
| ₹2,00,000 | Home-loan interest, Section 24(b) (old regime only) | Interest on a home loan for the house you live in is deductible up to ₹2,00,000 a year. HRA exemption has no fixed cap — enter the exemption your employer works out. |
| 10% / 15% / 25% / 37% | Surcharge above ₹50 lakh | Surcharge on the tax: 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore of taxable income. The 37% band above ₹5 crore applies only in the old regime — the new regime is capped at 25%. Then 4% cess is added on tax plus surcharge. |
The new regime wins for most salaried people — it only loses when your old-regime deductions are large enough to outweigh its lower rates. On ₹15,00,000 of salary you need roughly ₹5,45,000 of deductions for the old regime to catch up.
Common mistakes
The slabs look simple, but four readings trip people up. Each one can cost thousands a year.
Tax applies to taxable income, not gross salary — the ₹75,000 standard deduction comes off first. On ₹15,00,000 the slabs tax ₹14,25,000, not ₹15,00,000, and the difference is ₹11,700 of tax.
The standard deduction is ₹75,000 under the new regime but only ₹50,000 under the old regime. Mixing them up overstates the old regime's saving by ₹25,000 of income — about ₹7,800 of tax at the 30% slab.
₹1,50,000 of 80C is not enough on its own: on ₹15,00,000 the old regime still charges ₹2,10,600 with it, against ₹97,500 new. You need roughly ₹5,45,000 of deductions at that salary for the old regime to catch up.
Crossing ₹12,00,000 of taxable income does not suddenly cost ₹60,000 of tax — marginal relief caps it at the excess over ₹12,00,000. At ₹12,50,000 the tax is ₹52,000 with cess, not ₹70,200. This page applies the relief automatically.
Your questions, answered
It depends on your deductions. The new regime has lower slab rates and a ₹75,000 standard deduction, so it wins for most salaried people — on ₹15,00,000 of salary with no deductions it charges ₹97,500 against the old regime's ₹2,57,400. The old regime only wins when your deductions are large: at ₹25,00,000 of salary you need about ₹10,00,000 of deductions for it to come out ahead. Enter your real deductions above and compare the two totals.
Take your gross income, subtract the ₹75,000 standard deduction from salary, and tax what is left slab by slab: nil up to ₹4 lakh, 5% from ₹4–8 lakh, 10% from ₹8–12 lakh, 15% from ₹12–16 lakh, 20% from ₹16–20 lakh, 25% from ₹20–24 lakh and 30% above ₹24 lakh. Then apply the Section 87A rebate (up to ₹60,000 if taxable income is ₹12,00,000 or less), add surcharge above ₹50 lakh, and add 4% health and education cess. On ₹15,00,000 of salary that is ₹93,750 of slab tax plus ₹3,750 of cess — ₹97,500.
Section 87A gives resident individuals a rebate against the tax the slabs produce. Under the new regime for FY 2025-26 it is up to ₹60,000 when taxable income is ₹12,00,000 or less — exactly the slab tax on ₹12,00,000, so the tax becomes nil. Under the old regime it is up to ₹12,500 when taxable income is ₹5,00,000 or less. It applies only to income taxed at normal slab rates, not to capital gains taxed at special rates.
Without it, crossing the ₹12,00,000 rebate limit would be a cliff: at ₹12,10,000 of taxable income the slab tax jumps to ₹61,500 with no rebate at all. Marginal relief caps the tax at the amount by which your income exceeds ₹12,00,000 — so at ₹12,10,000 you pay ₹10,000 of tax (₹10,400 with cess), and at ₹12,50,000 you pay ₹50,000 (₹52,000 with cess). The relief fades out at about ₹12,70,000 of taxable income, where the ordinary slab tax becomes the smaller figure. It applies only in the new regime.
Section 80C up to ₹1,50,000 (EPF, PPF, ELSS, life insurance premium, tuition fees, home-loan principal), health insurance under Section 80D up to ₹25,000 (₹50,000 for a senior citizen), HRA exemption, home-loan interest under Section 24(b) up to ₹2,00,000 for the house you live in, your own NPS contribution under Section 80CCD(1B) up to ₹50,000, and other Chapter VI-A deductions. This calculator caps each one at its legal limit — enter what you actually pay and it takes the lower figure.
Almost none. The new regime allows the ₹75,000 standard deduction on salary (and on pension) and your employer's NPS contribution under Section 80CCD(2) — which this calculator does not model, since it is not part of your salary figure. Section 80C, 80D, HRA, home-loan interest and 80CCD(1B) are all unavailable under the new regime, which is why its slab rates are lower.
Surcharge is an extra percentage on the tax itself, charged when taxable income crosses ₹50 lakh: 10% above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore in both regimes, plus 37% above ₹5 crore in the old regime only (the new regime is capped at 25%). Health and education cess of 4% is then added on the tax plus surcharge. On a ₹60,00,000 salary the new-regime tax is ₹15,52,980, including ₹1,35,750 of surcharge and ₹59,730 of cess.
It should be close for salary plus other income taxed at normal slab rates, but it is an estimate, not your return. It does not cover capital gains or other special-rate income, house-property losses, the employer's NPS contribution, surcharge marginal relief, or the rounding of the final tax to the nearest ₹10 that Section 288 requires on the return itself. Your Form 16 and your return are the final word — check them against this estimate and ask a chartered accountant if they differ by more than a few rupees.
No. Every calculation runs entirely on this page — nothing is sent to a server, nothing is stored, and reloading the page clears your recent checks.
This page uses the FY 2025-26 (AY 2026-27) rates from the Finance Act 2025 (Union Budget 2025): the new-regime slabs under Section 115BAC, the old-regime slabs with the age-based exemptions, the ₹75,000 / ₹50,000 standard deductions, the Section 87A rebates (₹60,000 to ₹12,00,000 new; ₹12,500 to ₹5,00,000 old) with marginal relief in the new regime, the surcharge bands and the 4% health and education cess. Each component — slab tax, surcharge and cess — is rounded to the nearest rupee. Deductions are capped at their legal limits (80C ₹1,50,000; 80D ₹25,000, ₹50,000 for a senior citizen; home-loan interest ₹2,00,000; NPS 80CCD(1B) ₹50,000).
Rate checked 11 November 2026 against the Income Tax Department's tax-rates pages (incometaxindia.gov.in) and the e-filing portal (incometax.gov.in). Cross-checked against the ranking income tax calculators: ₹15,00,000 of salary gives ₹97,500 under the new regime on calcsolver.in and on calvix.org.in, which also gives ₹1,95,000 under the old regime with ₹2,00,000 of deductions — both figures match this calculator exactly. Two limits of this tool, stated plainly: the final tax on a return is rounded to the nearest ₹10 under Section 288, which this calculator does not apply (the difference is a few rupees at most), and surcharge marginal relief is not applied, so at incomes just above a surcharge threshold (₹50 lakh, ₹1 crore, ₹2 crore, ₹5 crore) the figure here can be slightly higher than the return. Capital gains and other special-rate income, house-property losses and the employer's NPS contribution under Section 80CCD(2) are not covered.
