Income Tax Calculator

India’s personal income tax for FY 2025-26 is most often discussed in the new-regime slab shape: no tax on the first ₹4 lakh of taxable income, then 5%, 10%, 15%, 20% and 30% on successive ₹4 lakh bands, plus 4% health and education cess. This page applies that sketch, and a simplified old-regime sketch, to the income you type. It is an estimate, not an intimation under section 143.

The cash-flow question

Salaried people in Gurugram, Ahmedabad and Chennai open a tax calculator in June when Form 16 arrives and again in January when they tweak investments. The new regime is the default for many, but old-regime deductions still matter for some HRA-heavy renters. IndiaKit lets you toggle the two sketches on the same ₹12 lakh income so the conversation with a CA starts from numbers, not from a forward.

The maths on this page

New-regime style estimate: taxable income is sliced as ₹0–4 lakh at 0%, next ₹4 lakh at 5%, next ₹4 lakh at 10%, next ₹4 lakh at 15%, next ₹4 lakh at 20%, and the rest at 30%. A 4% cess is then applied on the tax. For ₹12 lakh, that is ₹4 lakh × 0% + ₹4 lakh × 5% + ₹4 lakh × 10% = ₹60,000, plus cess ₹2,400, totalling ₹62,400, or about ₹5,200 a month.

The old-regime toggle on this page is simplified: ₹0–2.5 lakh at 0%, next ₹2.5 lakh at 5%, next ₹5 lakh at 20%, remainder at 30%, again with 4% cess. It does not model every deduction (80C, 80D, HRA) — use the HRA tool and your CA for those.

Surcharge, rebate, and standard-deduction details change in Finance Acts. Confirm current slabs, rebates and the chosen regime on incometax.gov.in before you file. IndiaKit will not ask for PAN, Aadhaar, or OTP.

₹12 lakh taxable income in the new-regime sketch

Karthik in Chennai has about ₹12 lakh of taxable income after the standard deduction his payroll already applied. On the new-regime sketch the estimate is ₹62,400 for the year, ₹5,200 a month. He compares the old-regime toggle, then checks whether HRA on a T. Nagar rental would still justify old regime — that second question belongs with Form 16 and a CA, not with this page alone.

What a bank still has to confirm

This is not the e-filing utility. Rebate provisions, surcharge, special-rate income (capital gains, lottery), and employer TDS mismatches are omitted. The official calculator and your Annual Information Statement on incometax.gov.in override anything shown here.

Common questions

Which financial year does this new-regime sketch follow?

It follows a FY 2025-26 new-regime style: nil tax to ₹4 lakh, then 5/10/15/20/30, plus 4% cess. Always re-read the latest Finance Act tables on incometax.gov.in; Parliament can change bands after this text is written.

Does the old-regime option subtract 80C or HRA automatically?

No. It only applies a simplified slab table. Enter taxable income after deductions if you are modelling old regime, or use the HRA exemption calculator for that piece.

Why is there a 4% extra on the tax?

That is the health and education cess applied on the computed income tax in this estimate, matching the cess commonly levied on personal income-tax liability. Confirm the cess line on the official utility.
