New regime tax slabs (default)

The new regime is the default for FY 2025-26 and FY 2026-27. Budget 2026 left the slabs unchanged.

  • Standard deduction: ₹75,000 for salary and pension.
  • Rebate: if taxable income is ₹12 lakh or less, a rebate of up to ₹60,000 makes the tax nil (section 87A, section 156 of the new Act). For a salaried person that means a salary of up to ₹12.75 lakh is tax-free. Just above ₹12 lakh of taxable income, marginal relief limits the tax to the income above ₹12 lakh.
  • Few deductions: most exemptions (HRA, 80C, 80D, home-loan interest on a self-occupied house) aren't allowed. The employer's NPS contribution is.

Standard deduction ₹50,000; rebate of up to ₹12,500 if taxable income is ₹5 lakh or less. In exchange for the higher rates, you keep the deductions: HRA, 80C (₹1.5 lakh), 80D, home-loan interest (₹2 lakh), NPS 80CCD(1B) (₹50,000) and others.

Both regimes add a 4% health and education cess, and a surcharge on very high incomes: 10% above ₹50 lakh, 15% above ₹1 crore, 25% above ₹2 crore, and in the old regime only 37% above ₹5 crore.

Worked example: ₹15 lakh salary

New regimeOld regime (no deductions)Old regime (₹4.25 lakh of deductions)

Tax incl. cess₹97,500₹2,57,400₹1,24,800

On ₹15 lakh, the old regime only wins with more than about ₹5.44 lakh of deductions beyond the standard deduction. Typically that means full 80C, health insurance, a large HRA exemption and home-loan interest. The calculator works this break-even point out for your salary.

Which regime should you choose?

  • Few deductions, or salary up to ₹12.75 lakh: the new regime almost always wins.
  • High rent in a big city plus a home loan plus full 80C: check both. The old regime can still win, usually at higher salaries.
  • Salaried people can switch every year when filing the return, whatever they told their employer for TDS. People with business or professional income face strict limits on switching back and forth, so check with a CA before leaving the default.

Self-employed or a freelancer? The freelancer tax calculator applies presumptive taxation (44ADA), where only 50% of receipts is taxed.

Frequently asked questions

Is income up to ₹12 lakh tax-free?
Under the new regime, yes: taxable income up to ₹12 lakh pays no tax because of the ₹60,000 rebate. Salaried people also get the ₹75,000 standard deduction, so a salary up to ₹12.75 lakh is tax-free. This doesn't apply to special-rate income such as capital gains.
Which is better, the new or old tax regime?
For most people, the new regime. The old regime is better only when your deductions (HRA, 80C, 80D, home-loan interest and others) are large. The calculator shows the break-even amount for your salary.
Are FY 2026-27 slabs different from FY 2025-26?
No. Budget 2026 kept the slabs, rebate, standard deduction, surcharge and cess unchanged. FY 2026-27 is the first year under the Income-tax Act 2025, which renumbers the sections (for example, the 87A rebate is section 156) without changing these rates.
Can I claim HRA in the new regime?
No. HRA exemption, 80C, 80D and home-loan interest on a self-occupied house are only available in the old regime. Use the HRA calculator to see how much exemption you'd get.
How is monthly TDS on salary worked out?
Your employer estimates the year's tax under the regime you choose and deducts roughly one-twelfth each month, adjusting as the year goes on. The monthly figure here is that simple average.
Can I change regime when I file my return?
Salaried people without business income can choose either regime every year when filing, even if they told their employer otherwise. Any extra tax or refund is settled with the return.
