After entering the required information, the calculator displays your estimated income tax liability, applicable tax rate, and total tax payable.

Income Tax Slabs in India for Tax Year 2026–27

India offers two income tax regimes for eligible individual taxpayers: the old tax regime and the new tax regime.

The new tax regime is the default option, while eligible taxpayers can choose the old tax regime subject to applicable conditions.

New Tax Regime Slabs

The following tax rates apply to individual taxpayers under the new tax regime for Tax Year 2026–27.

Resident individuals may also qualify for a rebate under Section 87A, subject to the applicable conditions. Under the new regime, the maximum rebate is ₹60,000 for eligible individuals with taxable income not exceeding ₹12 lakh. Marginal relief may also apply.

Old Tax Regime Slabs

Under the old tax regime, the general income tax slabs for individuals below 60 years of age are:

The old tax regime also provides different basic exemption limits for eligible resident senior citizens.

• Senior citizens aged 60–79 years: Basic exemption limit of ₹3 lakh.

• Super senior citizens aged 80 years or above: Basic exemption limit of ₹5 lakh.

These are general slab rates. Additional rules may apply depending on income type and taxpayer status.

Difference Between Old and New Tax Regimes

Understanding the differences between the two tax regimes is important before calculating your income tax.

The old regime may be beneficial for individuals who claim substantial deductions and exemptions. The new regime may be more suitable for people who prefer lower tax rates and fewer deduction requirements.

The best option depends on your income, investments, deductions, and financial circumstances.

How Is Income Tax Calculated?

Income tax is calculated by applying the relevant tax rates to different portions of your taxable income.

For example, suppose your taxable income under the new tax regime is ₹15,00,000.

The calculation would be:

• First ₹4,00,000: Nil tax.

• Next ₹4,00,000 at 5%: ₹20,000.

• Next ₹4,00,000 at 10%: ₹40,000.

• Remaining ₹3,00,000 at 15%: ₹45,000.

Total Income Tax = ₹1,05,000

Health and Education Cess at 4% = ₹4,200.

Total Tax Payable = ₹1,09,200

This example excludes any special tax treatment, surcharge, rebate, or other applicable adjustments.
