Work out your income tax

Which regime should you pick

The new regime is the default, and for most salaried people with few deductions it is also the cheaper one — the slabs are wider and the rebate under section 87A wipes out the tax on a taxable income up to ₹12 lakh. The old regime only wins once your deductions are large: a full 80C, health insurance under 80D, HRA you actually pay, and home-loan interest can together move the line.

Rather than argue about it, type your income and your deductions. The calculator works out both and tells you which one costs less, which is the only comparison that matters.

What the slabs are for FY 2026-27

Budget 2026 left the rates where Budget 2025 had put them, so the new regime still runs from nil up to ₹4 lakh through to 30% above ₹24 lakh, and the old regime still has its ₹2.5 lakh exemption and three rates above it. The table in the result shows exactly which slab charged what, so you can see where the money went rather than trusting a single number.

Marginal relief, and why ₹12,00,001 does not cost ₹61,500

Section 87A stops applying the moment your taxable income crosses ₹12 lakh, which on the raw slabs would mean one extra rupee of income triggering about ₹61,500 of tax. Marginal relief exists to stop that: the extra tax can never exceed the extra income that caused it. The same rule applies where surcharge kicks in at ₹50 lakh and above. This calculator applies it, which is why the figure just past a threshold looks sane.

This is a calculator, not tax advice. It applies the published slabs to the number you type. It does not know about capital gains, foreign income, arrears relief under section 89, or anything else your return might contain. For a filing you are signing, check the figure with a chartered accountant or against the department's own utility.

Frequently asked questions

Is the standard deduction available under the new regime?

Yes. Salaried taxpayers and pensioners get ₹75,000 under the new regime and ₹50,000 under the old one. Untick the salaried box if you are filing on business or professional income, where it does not apply.

Does this include surcharge and cess?

Both. The 4% health and education cess is shown as its own line, and surcharge is applied above ₹50 lakh at the rate for your income band, with marginal relief where a threshold is only just crossed.

Can I claim 80C under the new regime?

No. The new regime trades almost all deductions — 80C, 80D, HRA, LTA — for lower rates. The deductions field on this page is therefore only used when you select the old regime.

What about senior citizens?

The higher basic exemption limits for taxpayers aged 60 and above apply only under the old regime, and this calculator does not yet model them. If you are over 60 and comparing regimes, treat the old-regime figure here as slightly overstated.

Which financial year does this cover?

FY 2026-27, which is assessment year 2027-28. The slabs are unchanged from FY 2025-26, so the same figures apply if you are checking last year's return.
