Compute your income tax under the old and new regimes for FY 2026-27 and see which one saves you more.
Income tax is what you owe the government on your yearly earnings, and India now runs two parallel systems, the old regime with its many deductions and the new regime with lower slab rates but far fewer exemptions. Deciding which one leaves more money in your pocket is genuinely confusing, because it depends on how much you claim in deductions like rent, insurance, and provident fund. This calculator computes your liability under both regimes for the relevant financial year and tells you which one saves you more.
You enter your income and the deductions you are eligible for, such as the standard deduction, section 80C investments, and any others the form asks for. The tool then runs your numbers through both regimes at once and shows the tax under each, side by side, with the difference highlighted. Because it compares rather than assumes, you are not left guessing whether all your deductions actually beat the new regime's lower rates.
The method applies each regime's slab structure to your taxable income after the deductions that regime allows, then adds the health and education cess and any surcharge that applies at higher incomes. The old regime lets you subtract a long list of exemptions before the slabs bite, while the new regime gives a lower rate schedule but disallows most of them. Roughly speaking, the more you legitimately claim in deductions, the more the old regime tends to favour you, and the calculator makes that tipping point concrete for your figures. Because slab rates and limits are set by the government and can change, the tool reflects a specific financial year and you should confirm the current official rates for your situation.
Use this whenever you are choosing a regime, most often at the start of a job, when declaring your choice to an employer, or while filing your return. If you instead need a formal statement laying out each line of income and deduction to keep or submit, an income tax computation tool produces that document rather than a quick comparison.
It helps in a few real cases. A salaried person can see whether their rent and 80C investments justify staying in the old regime. A freelancer with few deductions can confirm the new regime is simpler and cheaper. Someone who just took a home loan can check how the added interest deduction shifts the balance.
All the computation runs in your browser, so your salary and deduction details never leave the device and nothing is sent to any server. There is no sign-up and no charge, and the only limit is your device's own memory, which a tax comparison will never approach. Tax rules carry exceptions this kind of tool cannot fully capture, so treat the result as a strong guide and verify anything unusual with a professional or the official portal.
It is built around a specific financial year's slabs and rules, shown on the tool itself, since rates change from year to year. If you are planning for a different year, confirm that year's official slabs before relying on the figure.
The old regime lets you subtract deductions like 80C, rent, and loan interest before tax applies, so if those add up to a large amount they can outweigh the new regime's lower rates. The more you legitimately claim, the more the old regime tends to win, which is exactly what the side-by-side view reveals.
Yes, the liability adds the standard health and education cess, and the surcharge that applies at higher income levels, so the number reflects total tax rather than just the slab amount. This matters most for high earners where the surcharge is significant.
It is designed mainly for salary and ordinary income with common deductions, and special-rate items like capital gains follow separate rules the tool may not fully model. For those, treat the output as a starting point and check the specific provisions.
Where the standard deduction applies to your income type, the calculator accounts for it, but you should still enter your other deductions yourself. Always sanity-check that the deductions shown match what you are actually entitled to claim.
It is an accurate planning and comparison tool, not a substitute for the official filing portal or professional advice on edge cases. Use it to choose a regime and estimate your bill, then verify the final numbers when you file.
