What is an Income Tax Calculator?

An online tax estimator that compares income tax liabilities under FY 2025-26 rules for the New Tax Regime (with updated ₹75,000 standard deduction) vs the Old Tax Regime.

Key Benefits of Using an Income Tax Calculator

  • Zero Tax Limit: Taxable income up to ₹7,00,000 pays ₹0 tax after Sec 87A rebate in New Regime.
  • Regime Optimization: Compare whether Chapter VI-A deductions make the Old Regime beneficial.

How FY 2025-26 Tax Is Calculated (Live Example)

Calculated for a salaried individual with a Gross Annual Income of ₹12,00,000 under FY 2025-26 rules:

Gross Annual Income ₹12,00,000
New Standard Ded. ₹75,000
New Net Taxable ₹11,25,000
New Regime Tax ₹75,400
New Regime Slab Calculation: ₹0–₹3L (0%) + ₹3L–₹7L (5% = ₹20k) + ₹7L–₹10L (10% = ₹30k) + ₹10L–₹11.25L (15% = ₹18.75k) = ₹68.75k + 10% NPS + 4% Cess = ₹75,400
Old Tax Regime (Without Deductions): Taxable ₹11,50,000 → Net Tax = ₹1,48,200
Regime Comparison Verdict: New Tax Regime saves ₹72,800 in tax for FY 2025-26!
Gross Income: ₹12,00,000 Old Regime Tax: ₹1,48,200 New Regime Tax: ₹75,400

How Old vs New Regime Tax Is Calculated

01

Two Regimes, Two Slab Structures

For FY 2025-26 (AY 2026-27), the New Tax Regime (default) taxes income at 0% up to ₹4 Lakh, then 5%, 10%, 15%, 20%, 25%, and 30% in ₹4 Lakh steps up to ₹24 Lakh and beyond, with a flat ₹75,000 standard deduction for salaried taxpayers. The Old Tax Regime uses wider bands (Nil to ₹2.5 Lakh, 5% to ₹5 Lakh, 20% to ₹10 Lakh, 30% above) with a ₹50,000 standard deduction, but allows exemptions like HRA and deductions under 80C, 80D, and 24(b) that the New Regime does not.

02

Section 87A Rebate and Marginal Relief

Under the New Regime, a Section 87A rebate makes tax fully zero for net taxable income up to ₹12,00,000, and marginal relief caps the tax on incomes just above that threshold so it never exceeds the amount of income over ₹12 Lakh. The Old Regime has a separate, lower 87A rebate that applies only when net taxable income is at or below ₹5,00,000, with no marginal relief provision.

03

Worked Regime Comparison Example

For a salaried person earning ₹12,50,000 with ₹1,50,000 in Section 80C and ₹25,000 in Section 80D: under the New Regime, ₹12,50,000 − ₹75,000 standard deduction = ₹11,75,000 net income, which falls under the ₹12 Lakh rebate threshold, making net tax ₹0. Under the Old Regime, the same income after standard deduction and 80C/80D drops to ₹10,25,000 net income, producing a tax of roughly ₹1,32,600 including cess, so the New Regime saves ₹1,32,600 in this case.

04

Choosing a Regime and Related Tools

Taxpayers with few deductions (no home loan, minimal 80C/80D, no HRA claim) generally benefit from the New Regime's lower slabs and higher rebate threshold, while those with substantial HRA, home loan interest, or 80C investments often still save more under the Old Regime. Use the HRA Exemption Calculator to compute your exact exempt HRA figure, or the Salary Calculator to see the take-home impact of each regime.

Questions, answered

Quick answers about how this tool works.

For the Financial Year 2025-26, the standard deduction for salaried individuals and pensioners has been increased to ₹75,000 under the New Tax Regime. Under the Old Tax Regime, the standard deduction remains at ₹50,000.

The New Tax Regime is the default tax regime in India for FY 2025-26. If you wish to file your taxes under the Old Tax Regime, you must actively opt out of the New Regime when filing your income tax return.

Under the New Tax Regime for FY 2025-26, a tax rebate under Section 87A is available for resident individuals whose net taxable income does not exceed ₹12,000,000. This rebate is up to ₹60,000, making taxable income up to ₹12 lakh completely tax-free.

Marginal relief prevents a sudden increase in tax when taxable income marginally exceeds ₹12 Lakh. If your income is slightly above ₹12 Lakh, your tax is capped at the amount exceeding ₹12 Lakh. For example, if taxable income is ₹12,05,000, the tax is capped at ₹5,000 instead of the standard slab tax of ₹60,750.

Slabs under the New Tax Regime are: Up to ₹4 Lakh: Nil; ₹4 Lakh to ₹8 Lakh: 5%; ₹8 Lakh to ₹12 Lakh: 10%; ₹12 Lakh to ₹16 Lakh: 15%; ₹16 Lakh to ₹20 Lakh: 20%; ₹20 Lakh to ₹24 Lakh: 25%; Above ₹24 Lakh: 30%.

For individuals under 60 years under the Old Regime: Up to ₹2.5 Lakh: Nil; ₹2.5 Lakh to ₹5 Lakh: 5%; ₹5 Lakh to ₹10 Lakh: 20%; Above ₹10 Lakh: 30%. For Senior Citizens (60-80), exemption is up to ₹3 Lakh, and for Super Senior Citizens (80+), it is up to ₹5 Lakh.

The New Tax Regime allows very few deductions. Key eligible deductions include the Standard Deduction of ₹75,000 (for salaried/pensioners), employer contribution to NPS under Section 80CCD(2), and deduction for Agniveer Corpus Fund under Section 80CCH.

Under the Old Tax Regime, you can claim Section 80C (up to ₹1.5 Lakh for PPF, EPF, ELSS, LIC, Home Loan Principal), Section 80D (Health Insurance up to ₹1 Lakh depending on age), HRA exemption, LTA exemption, and Section 24b (Home Loan Interest up to ₹2 Lakh).

HRA tax exemption is the minimum of three values: (1) Actual HRA received, (2) Rent paid minus 10% of basic salary + DA, or (3) 50% of basic salary for metro cities (40% for non-metro cities). HRA exemption is only available under the Old Tax Regime.

Yes, under the New Tax Regime, the maximum surcharge rate is capped at 25% for taxable incomes exceeding ₹2 Crore (including above ₹5 Crore). In the Old Tax Regime, the surcharge is up to 37% for incomes exceeding ₹5 Crore.
