Income Tax Calculator

Every April your employer asks which regime you want for TDS, and every July you choose again when you file. The new regime is the default from tax year 2026-27 under section 202 of the Income-tax Act, 2025, so you only pay old regime rates if you opt out. This calculator shows both answers at once, so you can see in a few seconds whether your 80C, HRA and home loan claims are worth giving up the lower slabs.

New regime slabs for FY 2026-27: up to ₹4 lakh nil, ₹4 to 8 lakh 5%, ₹8 to 12 lakh 10%, ₹12 to 16 lakh 15%, ₹16 to 20 lakh 20%, ₹20 to 24 lakh 25%, and above ₹24 lakh 30%. Salaried people get a ₹75,000 standard deduction, and the section 156 rebate of up to ₹60,000 makes tax nil when taxable income is ₹12 lakh or less. That is why a salary of ₹12.75 lakh pays no tax. Just above ₹12 lakh, marginal relief keeps your tax from being more than the income above ₹12 lakh, and the calculator applies it for you.

Old regime slabs: up to ₹2.5 lakh nil (₹3 lakh at 60 to 79, ₹5 lakh at 80 and above), up to ₹5 lakh 5%, ₹5 to 10 lakh 20%, and above ₹10 lakh 30%. The standard deduction is ₹50,000 and the rebate is up to ₹12,500 when taxable income is ₹5 lakh or less. In exchange you can claim 80C up to ₹1.5 lakh, HRA exemption, home loan interest up to ₹2 lakh on a self-occupied house, 80D health insurance, ₹50,000 extra NPS under 80CCD(1B) and professional tax.

Both regimes add surcharge on high incomes: 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore, and 37% above ₹5 crore in the old regime only, because the new regime stops at 25%. Marginal relief is applied at each step. Then 4% health and education cess is added on tax plus surcharge. The final figure is rounded to the nearest ₹10, as the return does.

If the new regime wins, the calculator also tells you roughly how much more you would need to claim in deductions for the old regime to break even. That number is useful when you are deciding whether a bigger home loan, an ELSS top up or a health policy changes the answer.

Salary figures are private. Everything here is worked out by code running in your browser tab. Nothing you type is sent to TaskNinja, saved, or logged, and there is no account. We only count anonymous events such as the calculator being used, never the amounts.

This is an estimate for resident and non-resident individuals with salary and normal slab-rate income. It does not handle capital gains taxed at special rates, lottery winnings, agricultural income, business presumptive schemes or HUF. Employer NPS, leave encashment, gratuity and similar items should already be excluded from the salary you enter if they are exempt. For filing, use the figures in your Form 16 and the official e-filing portal, and ask a chartered accountant when in doubt.
