How do I use the income tax calculator?

1. Enter your gross annual income: Add your total income before any deductions, including salary, bonus, and other taxable receipts. 2. Select your age group: Choose below 60, 60 to 80, or above 80. Age affects the basic exemption limit under the old regime. 3. Add your deductions: Enter Section 80C investments, 80D health premiums, home loan interest under Section 24b, HRA exemption, and any other eligible deductions. These apply to the old regime. 4. Compare the two regimes: The calculator shows tax under both regimes side by side, with a full slab by slab breakdown for each. 5. Review the recommendation: See which regime costs less, how much you save, and your effective tax rate. Use Share to save or send the comparison.

What are the current tax slabs under the new regime?

Under the new regime for FY 2026-27: income up to ₹4L is tax-free, 4-8L at 5%, 8-12L at 10%, 12-16L at 15%, 16-20L at 20%, 20-24L at 25%, and above 24L at 30%. The rebate under section 87A means income up to ₹12L (₹12.75L with standard deduction) is effectively tax-free.

What is the standard deduction?

The standard deduction is an automatic deduction from salary income. For FY 2026-27, this calculator applies ₹75,000 under the new regime and ₹50,000 under the old regime before computing taxable income.

What deductions can I claim under the old regime?

Common deductions include: Section 80C (PPF, ELSS, EPF, life insurance — up to ₹1.5L), Section 80D health insurance (typically ₹25,000 each for self/family and parents, rising to ₹50,000 where senior-citizen rules apply), HRA exemption, Section 24b home loan interest (up to ₹2L), and NPS under 80CCD(1B). These are generally not available in the new regime.

What is surcharge and cess?

Surcharge is an additional tax on high incomes: 10% (₹50L-1Cr), 15% (₹1-2Cr), 25% (₹2-5Cr), and 37%/25% above ₹5Cr (old/new regime). Health and Education Cess is 4% on (tax + surcharge), applicable to all taxpayers. Both are included in this calculator's results.

About the income tax calculator

This calculator estimates your income tax for the financial year under both the old and new regimes, then tells you which one leaves more money in your pocket. It applies the latest slab rates, the standard deduction, the Section 87A rebate, surcharge, and the 4% health and education cess so the figure you see reflects what you would actually pay.

It is built for salaried professionals and anyone weighing the two regimes. The old regime rewards deductions like Section 80C, 80D, home loan interest, and HRA, while the new regime offers lower slab rates and a higher standard deduction but almost no deductions. The right choice depends on how much you claim.

Treat the result as a close estimate for planning. Your actual liability can differ once perquisites, capital gains, other heads of income, and employer reporting are accounted for. For filing, confirm the numbers with the income tax portal or a qualified advisor.

Total tax = (sum of income taxed in each slab) + surcharge + 4% cess, minus the Section 87A rebate

Taxable income is gross income minus the standard deduction and eligible deductions
Each slab taxes only the portion of income that falls within it, at that slab's rate
Surcharge applies at higher income levels, with marginal relief
The Section 87A rebate can reduce tax to zero up to the prescribed income limit

The new regime uses a single set of slabs with a higher standard deduction of ₹75,000 and a rebate up to ₹12,00,000 of taxable income. The old regime uses age based slabs, a ₹50,000 standard deduction, and lets you claim deductions such as 80C, 80D, 24b, and HRA.

A worked example

Suppose your gross income is ₹15,00,000, you are below 60, and you claim ₹1,50,000 under 80C, ₹25,000 under 80D, ₹2,00,000 of home loan interest, and ₹50,000 of other deductions.

Gross income: ₹15,00,000
Old regime deductions (incl. standard): ₹4,75,000
Old regime taxable income: ₹10,25,000
Old regime tax: ₹1,24,800
New regime taxable income: ₹14,25,000
New regime tax: ₹97,500
Recommended regime: New (saves ₹27,300)

Even with sizeable deductions, the new regime costs ₹97,500 against ₹1,24,800 under the old regime, a saving of ₹27,300 here. The more deductions you can genuinely claim, the more the old regime closes that gap, which is why comparing both matters.

It depends on your deductions. The new regime offers lower tax rates and a Section 87A rebate that makes tax zero up to ₹12 lakh of taxable income (₹12.75 lakh gross salary after the ₹75,000 standard deduction), with marginal relief tapering just above that, but it allows almost no deductions. The old regime has higher rates but lets you claim deductions under 80C, 80D, HRA, home loan interest, and more. If your total deductions are substantial, the old regime can still be better. Use this calculator to compare both.

Slab rates, the standard deduction, and the rebate limit are set in the annual Budget and can change. This tool reflects the rules for the supported financial year.
Deductions only help if you actually invest or spend to claim them. Locking money into 80C instruments purely to save tax can be a poor trade if the returns do not suit your goals.
Surcharge applies once income crosses ₹50,00,000, and marginal relief limits how sharply it can rise just past each threshold.
This is an estimate of tax on salary and ordinary income. Capital gains, perquisites, and income from other sources follow their own rules and may change your final liability.
