How this works

India lets you choose between two ways of being taxed. This tool works out both, so you can pick the cheaper one.

1

The Old regime

Higher tax rates, but you can subtract deductions like 80C, 80D, HRA and home-loan interest. Great if you invest and claim a lot.

2

The New regime

Lower, simpler slabs but almost no deductions — just a bigger ₹75,000 standard deduction. It's now the default for most people.

3

We compare both

We apply the correct slabs, the Section 87A rebate, surcharge and 4% cess to each, then show you the winner — and the break-even.

Frequently Asked Questions

What's the difference between the Old and New tax regimes? ▼
The Old regime has higher slab rates but lets you claim exemptions and deductions — Section 80C, 80D, HRA, home-loan interest and more. The New regime has lower slab rates and a higher basic exemption, but removes most of those deductions. This calculator works out your tax under both and highlights the one that costs you less.
Which regime should I choose? ▼
It depends on how much you can deduct. If you claim a lot — full 80C, HRA, home-loan interest, 80D — the Old regime can come out ahead. If you have few deductions, the New regime's lower rates usually win. The calculator even shows the break-even deductions: the exact amount at which the Old regime overtakes the New one, so you don't have to guess.
Is the New regime the default now? ▼
Yes. Since FY 2023-24 the New regime is the default, and it stays the default for FY 2025-26. You can still opt for the Old regime when you file your return if it works out cheaper for you.
Which deductions can I enter, and do they apply to both regimes? ▼
Section 80C (up to ₹1.5 lakh), 80D health insurance, the extra ₹50,000 NPS deduction under 80CCD(1B), HRA exemption and home-loan interest all reduce tax under the Old regime only. The one exception is employer NPS under 80CCD(2), which is allowed under both regimes — enter it in the Advanced section and it lowers tax either way.
Does it handle age, standard deduction, rebate, surcharge and cess? ▼
Yes. Pick your age band (below 60, 60–80 or 80+) to apply the correct Old-regime basic exemption. Tick the salaried/pensioner box for the standard deduction (₹75,000 New, ₹50,000 Old). It also applies the correct slabs, the Section 87A rebate, surcharge with marginal relief on high incomes, and the 4% Health & Education Cess — for both regimes.
Can I see how the tax was actually calculated? ▼
Yes — open “Show the maths” under each regime to see the tax built up slab by slab, the 87A rebate, any surcharge and the 4% cess, all adding up to the total. The calculator also shows your effective rate, your marginal rate and your estimated monthly take-home.
Can I switch between the Old and New regime every year? ▼
If you earn salary or pension income, yes — you can pick whichever regime is cheaper each year when you file your return. If you have business or professional income and you opt out of the New regime, you can usually switch back to it only once, so choose carefully.
How is the HRA exemption calculated? ▼
Your exempt HRA is the least of three amounts: the actual HRA you received; the rent you paid minus 10% of your basic salary (plus DA); and 50% of basic if you live in a metro (Delhi, Mumbai, Kolkata or Chennai) or 40% elsewhere. Use the “Work out my exempt HRA” helper and it fills the figure in for you. HRA is an Old-regime exemption only.
What income can I enter — does it include capital gains? ▼
This tool is built for income taxed at the normal slab rates — salary, pension, interest, rent and similar. Special-rate incomes such as capital gains or lottery winnings are taxed under their own fixed rates and aren't modelled here, so enter only your slab-rate income for an accurate comparison.
What's the difference between 80CCD(1B) and 80CCD(2)? ▼
80CCD(1B) is your own extra NPS contribution — up to ₹50,000, and it reduces tax under the Old regime only. 80CCD(2) is your employer's NPS contribution — up to 14% of basic salary — and it's allowed under both regimes, which is why it sits in its own section.
What are surcharge and marginal relief? ▼
Surcharge is an extra levy on high incomes — 10% of tax above ₹50 lakh, rising to 15%, 25% and (Old regime) 37% at higher incomes; the New regime caps it at 25%. Marginal relief ensures that just crossing one of these thresholds never costs you more in extra tax than the extra income you earned. The calculator applies both automatically.
Which financial year does this cover, and is my data private? ▼
It uses the slabs and rules for FY 2025-26 (AY 2026-27). Everything runs in your browser — your salary and deduction figures are never uploaded, stored, or seen by anyone.
