What is an Income Tax Calculator?
An income tax calculator is a free online tool that computes your tax liability based on your annual income, regime choice, and deductions under Indian tax law. This income tax calculator covers both the old and new regime for AY 2025-26 and applies the correct slabs, Section 87A rebate, surcharge, and 4% Health & Education Cess — giving you results identical to official government computation. Unlike spreadsheets or manual working, it updates instantly as you adjust your income or deductions.
How to Use This Income Tax Calculator
Using this income tax calculator takes under a minute. Select your Assessment Year (default AY 2025-26) and toggle between Old Regime and New Regime. Enter your annual gross income using the input box or the slider. If you chose Old Regime, the deductions panel appears automatically — enter your Section 80C investments, health insurance premium under 80D, HRA exemption, and any other deductions. The income tax calculator shows your total tax, effective rate, and monthly take-home in real time. Switch to the Comparison tab to see both regimes side by side.
Income Tax Calculator for Salaried Employees
Salaried employees get a standard deduction of ₹50,000 under the old regime and ₹75,000 under the new regime. This income tax calculator applies the standard deduction automatically — you do not need to enter it separately. For most salaried employees earning between ₹7L and ₹15L per year, the new regime delivers lower tax if total claimed deductions stay below ₹3.75 lakh. Use the Comparison tab in this income tax calculator to see exactly which regime saves you more given your specific deduction profile.
How Tax Slabs Work in India
Indian income tax uses a progressive slab system — income is taxed at increasing rates as it crosses higher brackets. Under the new regime for AY 2025-26, the first ₹3 lakh is tax-free, with rates rising from 5% to 30% above ₹15 lakh. The Section 87A rebate ensures zero tax for new-regime taxpayers with taxable income up to ₹7 lakh. Old regime slabs are slightly different and offer a richer set of deductions. This income tax calculator applies surcharge on high incomes automatically — 10% for income above ₹50 lakh, up to 37% for old regime taxpayers above ₹5 crore. The 4% Health & Education Cess is always added to the final tax figure. This free online tool handles all these rules so you never need to compute them manually.
Old Regime vs New Regime — Which is Better?
The new regime offers simpler taxation with no deduction paperwork and lower slab rates for mid-range incomes. The old regime suits taxpayers who maximise deductions through investments in PPF, ELSS, and insurance. This income tax calculator computes both simultaneously so you can see exact savings without switching between tools. As a rule of thumb: if your total deductions exceed ₹3–3.75 lakh, old regime likely wins. Otherwise, new regime pays less. The Comparison tab in this income tax calculator gives a personalised answer for your income and deduction profile in seconds.
- New regime — standard deduction ₹75,000, no other deductions, lower slab rates
- Old regime — standard deduction ₹50,000 plus 80C, 80D, HRA, and other exemptions
- New regime is default from FY 2023-24 onwards unless you opt out
- Senior citizens (60–80) get higher basic exemption under old regime (₹3L instead of ₹2.5L)
- Super senior citizens (above 80) enjoy ₹5L basic exemption under old regime
- Section 87A rebate: taxable income ≤ ₹7L (new) or ≤ ₹5L (old) → zero tax
Frequently Asked Questions
Which income tax calculator is most accurate?
Our income tax calculator uses the exact India AY 2025-26 tax slabs for both old and new regime, including Section 87A rebate, surcharge brackets (10%–37%), and 4% Health & Education Cess. The formula mirrors the official Income Tax Department calculation. No ads, no sign-up, no data collected.
How does this income tax calculator work?
Enter your annual income, select old or new regime, add your deductions (for old regime) and the calculator instantly computes your taxable income, slab-wise tax, Section 87A rebate, surcharge if applicable, 4% cess, and final tax payable. The monthly take-home is your annual income minus total tax divided by 12.
Should I choose old or new tax regime in 2025-26?
It depends on your deductions. If your total deductions (80C + 80D + HRA + standard deduction ₹50,000) exceed approximately ₹3.75 lakh, old regime is usually better. For those with fewer deductions or no HRA, the new regime often results in lower tax. Use the Comparison tab to see which saves you more for your specific situation.
What deductions can I claim under old tax regime?
Under the old tax regime you can claim: standard deduction of ₹50,000, Section 80C up to ₹1.5 lakh (PPF, ELSS, LIC premiums, home loan principal, NSC, tuition fees), Section 80D up to ₹75,000 (health insurance for self, family and parents), HRA exemption if living in rented accommodation, and various other deductions under 80E (education loan), 80G (donations), 80TTA (savings interest), and more.
Is income above ₹7 lakh tax-free under new regime?
No. Income above ₹7 lakh is taxable under the new regime. However, the Section 87A rebate ensures that if your taxable income (after ₹75,000 standard deduction) does not exceed ₹7 lakh, the tax computed on it is fully rebated — bringing your net tax to zero. So a gross income of up to approximately ₹7.75 lakh can result in zero tax under the new regime with the standard deduction applied.
