Income tax calculator FY 2025-26 - new vs old regime, compared line by line
Most income tax calculators show one number. This one shows the whole working: gross income, standard deduction, every deduction section you claim, the slab-by-slab tax, Section 87A rebate with marginal relief, surcharge, and the 4% health & education cess-for both regimes, for FY 2025-26 (AY 2026-27) and FY 2024-25. The verdict card names the cheaper regime and the exact rupees you save by choosing it.
New regime slabs - FY 2025-26 (AY 2026-27)
The FY 2025-26 new regime is the default regime. With the enhanced 87A rebate, slab-rate income up to ₹12 lakh (₹12.75 lakh with the ₹75,000 standard deduction) pays zero tax.
| Taxable income | Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 - ₹8,00,000 | 5% |
| ₹8,00,001 - ₹12,00,000 | 10% |
| ₹12,00,001 - ₹16,00,000 | 15% |
| ₹16,00,001 - ₹20,00,000 | 20% |
| ₹20,00,001 - ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Old regime slabs - unchanged in FY 2025-26
The old regime keeps its slabs but rewards deductions: Section 80C (up to ₹1.5 lakh), 80D health premiums, 80CCD(1B) NPS (₹50,000), HRA exemption and Section 24(b) home-loan interest (₹2 lakh). The basic exemption is age-based.
| Slab | Below 60 / 60-79 / 80+ | Rate |
|---|---|---|
| Up to the basic exemption | ₹2.5L / ₹3L / ₹5L | Nil |
| Next slab up to ₹5,00,000 | 5% | 5% |
| ₹5,00,001 - ₹10,00,000 | 20% | 20% |
| Above ₹10,00,000 | 30% | 30% |
New regime vs old regime - how to choose
A rule of thumb: the old regime only wins when your total exemptions and deductions (HRA + 80C + 80D + NPS + 24(b)) are large relative to income - roughly ₹4-5 lakh of claims around the ₹15-20 lakh income band. Below ₹12 lakh taxable, the new regime is almost always cheaper. Above ₹24 lakh, it depends on your claims. Instead of memorising break-evens, move the sliders and read the verdict - then refine your deduction strategy with the HRA calculator, the 80C tax-savings estimator and professional tax planning.
Surcharge, marginal relief and cess
Above ₹50 lakh of taxable income a surcharge applies - 10%, 15% and 25% tiers (the old regime adds a 37% tier above ₹5 crore) - with marginal relief so the extra tax never exceeds the extra income. The new regime’s 87A rebate also carries marginal relief just above ₹12 lakh. Finally, a 4% health & education cess applies on tax plus surcharge. Every line appears in the slab-wise tables above the fold.
Frequently asked questions
Which is better for me - the new tax regime or the old regime in FY 2025-26?
It depends on your deductions. The new regime (FY 2025-26) has wider nil-tax slabs and a Section 87A rebate that makes income up to ₹12 lakh effectively tax-free, but allows almost no deductions. The old regime wins only when your 80C, 80D, HRA, NPS and home-loan-interest deductions are large enough. This calculator compares both on your exact numbers and names the cheaper regime.
Is income up to ₹12 lakh really tax-free in FY 2025-26?
Under the new regime, yes for slab-rate income: the FY 2025-26 slabs plus the enhanced Section 87A rebate (up to ₹60,000) bring tax to zero up to ₹12 lakh of taxable income - ₹12.75 lakh for salaried taxpayers after the ₹75,000 standard deduction. Marginal relief keeps tax fair just above the ceiling.
What is the standard deduction for FY 2025-26 (AY 2026-27)?
₹75,000 under the new regime and ₹50,000 under the old regime, available against salary income. This calculator applies it automatically based on the regime and financial year you pick.
Does the new regime allow 80C, 80D, HRA or home-loan deductions?
No. The new regime drops Chapter VI-A deductions (80C, 80D, 80CCD(1B)), HRA exemption and Section 24(b) home-loan interest on a self-occupied house. That is why the comparison matters - this tool applies those deductions only to the old-regime column.
How are surcharge and cess calculated on income tax?
Surcharge applies above ₹50 lakh of taxable income: 10% up to ₹1 crore, 15% up to ₹2 crore, 25% above that in the new regime (the old regime has a 37% tier above ₹5 crore). Marginal relief caps the extra tax at the extra income. A 4% health and education cess is added on tax plus surcharge - all computed line-by-line in the slab tables on this page.
What changed between FY 2024-25 and FY 2025-26 in the new regime?
FY 2025-26 widened the slabs (nil up to ₹4 lakh, then 5% steps up to 30% above ₹24 lakh) and raised the 87A rebate ceiling from ₹7 lakh to ₹12 lakh of taxable income. FY 2024-25 used nil up to ₹3 lakh with a ₹7 lakh rebate ceiling. Use the financial-year toggle to compare both.
Is this income tax calculator a filing tool?
No. It is an educational illustration for resident individuals covering slab-rate salary and other income. It does not model capital gains, special-rate income, employer NPS under 80CCD(2), or every deduction section. Confirm your computation with a Chartered Accountant before filing.
What is the last date to file ITR for FY 2025-26?
For most salaried individuals the due date is 31 July 2026 (AY 2026-27), unless the government notifies an extension. Belated returns can be filed later with a late fee, but some losses can no longer be carried forward.
Do I need to file a return if my income is below the taxable limit?
Filing is mandatory if gross income exceeds the basic exemption before deductions, and advisable even below it if TDS was deducted (to claim a refund) or for visa and loan applications that ask for ITRs.
