New regime saves you ₹1,08,420 this year.Your current old-regime deductions total ₹1,75,000. You would need about ₹5,49,000 of deductions for the old regime to break even — only worth it if those are investments you would make anyway.
Monthly TDS checkYour employer should deduct roughly ₹8,385 per month under the new regime. If your payslip TDS is far off, update your investment declaration.

How this income tax calculator works

This calculator follows the same sequence a chartered accountant uses for FY 2025-26 (AY 2026-27) regular income:

  1. Add salary and other income to get gross total income.
  2. Apply the standard deduction — ₹75,000 in the new regime, ₹50,000 in the old regime — for salaried taxpayers.
  3. Subtract old-regime deductions (80C, 80CCD(1B), 80D, HRA exemption, home loan interest, others) with their legal caps.
  4. Compute slab tax for both regimes, apply the Section 87A rebate with marginal relief, add surcharge above ₹50 lakh with marginal relief, and finish with 4% cess.
  5. Recommend the regime with the lower total and show the deduction break-even.

With the Section 87A rebate, taxable income up to ₹12 lakh pays zero tax. For salaried taxpayers, that means no tax up to ₹12.75 lakh of gross salary after the standard deduction.

The old regime keeps deductions alive: 80C up to ₹1.5 lakh, NPS ₹50,000 under 80CCD(1B), health insurance under 80D, HRA exemption, and home loan interest up to ₹2 lakh on a self-occupied house. Its Section 87A rebate is smaller — up to ₹12,500 when taxable income stays within ₹5 lakh.

Income tax calculator FAQs

Which tax regime is better for FY 2025-26?

For most salaried taxpayers with few deductions, the new regime is cheaper because of lower slab rates, a ₹75,000 standard deduction, and zero tax up to ₹12 lakh taxable income. The old regime wins only when your total deductions — 80C, 80D, HRA exemption, home loan interest, NPS — are large. This calculator shows the exact break-even for your numbers.

Is income up to ₹12 lakh really tax-free in the new regime?

Yes, for FY 2025-26 the Section 87A rebate makes tax zero when taxable income is up to ₹12 lakh. Salaried taxpayers effectively pay no tax up to ₹12.75 lakh gross salary after the ₹75,000 standard deduction. Marginal relief applies just above the limit so a small raise cannot leave you worse off.

What is marginal relief under Section 87A?

If your taxable income is slightly above ₹12 lakh, your tax is capped at the amount by which income exceeds ₹12 lakh. For example, at ₹12,10,000 taxable income the tax before cess is limited to ₹10,000 instead of the slab-computed ₹61,500.

What deductions can I claim in the new regime?

Very few. The main ones are the ₹75,000 standard deduction on salary and employer NPS contribution under Section 80CCD(2). Popular deductions such as 80C, 80D, HRA exemption, and self-occupied home loan interest are available only in the old regime.

What are the old regime slabs for senior citizens?

For those aged 60 to 79 the basic exemption is ₹3 lakh, and for those 80 or above it is ₹5 lakh. The 5%, 20%, and 30% bands above the exemption are otherwise the same, and this calculator applies them when you pick your age group.

Does this calculator include surcharge and cess?

Yes. It adds surcharge from 10% to 37% (capped at 25% in the new regime) for taxable income above ₹50 lakh with marginal relief at every threshold, and 4% health and education cess on the final amount.

Can I switch between regimes every year?

Salaried taxpayers without business income can choose either regime each year while filing the return. Those with business or professional income can switch out of the new regime essentially only once, so plan carefully.

Is this calculator enough for ITR filing?

No. It is a planning estimate for regular income. Capital gains, business income, agriculture income, and special-rate incomes are not modelled. Verify final numbers with the official income tax portal or a chartered accountant.
