[Start free](/signup?via=tool-old-vs-new-tax-regime-calculator) ## How the old vs new regime calculator works The two regimes trade off in a simple way. The new regime has lower slab rates, a bigger INR 75,000 standard deduction and a rebate that makes taxable income up to INR 12 lakh tax-free, but almost no deductions. The old regime keeps higher rates and a smaller INR 50,000 standard deduction, and lets you subtract HRA, 80C, 80D, NPS under 80CCD(1B), home-loan interest and more. This calculator runs your numbers through both regimes at once, using the same engine Kosh uses inside the app. It then works out a break-even figure: how much more in old-regime deductions you would need before the old regime costs the same as the new one. If that number is larger than anything you could realistically claim, the new regime is your answer. Employer NPS under 80CCD(2) is deductible in both regimes (up to 14% of basic in the new, 10% in the old), so it doesn't change the comparison much. Your own NPS, 80C, 80D, HRA and home-loan interest are what tip the balance. Old regime wins when: deductions claimed > break-even deductions for your salary ## Worked example: Rahul, INR 24 lakh in Mumbai with every deduction Rahul pays INR 45,000 a month in rent in Mumbai, maxes out 80C and his own NPS, and insures himself and his senior-citizen parents. That's INR 7.45 lakh of old-regime deductions, including INR 4.2 lakh of HRA. Even so, the old regime costs INR 3,21,360 against INR 2,92,500 in the new regime. He would need about INR 92,500 more in deductions, such as a home loan, for the old regime to break even. New regime saves you INR 28,860 Tax: INR 2,92,500 a year, INR 24,375 a month New regime**INR 2,92,500** Old regime**INR 3,21,360** Old-regime deductions now**INR 7,45,000** Gross income INR 24,00,000 − Standard deduction INR 75,000 Taxable income INR 23,25,000 Tax on slabs INR 2,81,250 \+ Health & education cess (4%) INR 11,250 Total tax INR 2,92,500 The old regime needs about INR 92,500 more in deductions before it beats the new one for you.

Tell your employer at the start of the year so the right TDS is deducted, but the final choice is made in your ITR. - If you have business or professional income, you can leave the new regime only once in your life and come back only once. - At most salaries the old regime needs INR 4 lakh to INR 8 lakh of deductions to win. Without a home loan or large rent, it rarely does. - Below INR 12.75 lakh of salary the new regime always wins, because your tax there is zero. ## Frequently asked questions At what salary does the old regime become better? There's no single salary: it depends on your deductions. Roughly, at INR 15 to INR 25 lakh the old regime needs INR 5 lakh to INR 8 lakh of deductions (HRA, 80C, 80D, NPS and home-loan interest together) before it wins. Use the break-even number in the calculator for your exact case. Can I switch between the old and new regime every year? If your income is from salary, pension, interest or rent, yes: you pick a regime each year when filing your return. If you have business or professional income, you can opt out of the new regime only once and return to it only once. Which deductions are allowed in the new regime? The INR 75,000 standard deduction, employer NPS contribution under 80CCD(2) up to 14% of basic, the deduction for Agniveer corpus contributions, and family pension deduction. HRA, 80C, 80D, home-loan interest on a self-occupied house and your own NPS are not allowed. I told my employer the wrong regime. Can I still change it? Yes. The choice you give your employer only decides how much TDS is deducted during the year. You can pick the other regime when you file your ITR; you'll either get a refund or pay the difference as self-assessment tax. Does the new regime make sense if I have a home loan? For a self-occupied home, the new regime gives no deduction for interest or principal, so a large home loan is the most common reason the old regime wins. Check with your numbers: interest of INR 2 lakh is worth up to INR 62,400 a year in the old regime at the 30% slab. ## Sources and assumptions - [Income Tax Department](https://www.incometax.gov.in/) - [Union Budget 2026-27](https://www.indiabudget.gov.in/) Rules and rates last checked on 25 October 2026.
