Old Regime vs New Regime - When to Choose What?

Use this quick decision guide if you don't want to run the calculator for every scenario.

Choose Old Regime if you have:

  • Home loan with large interest (close to ₹2L deduction)
  • HRA exemption (paying significant rent)
  • Full 80C investment (₹1.5L in EPF/PPF/LIC)
  • Family health insurance (80D near ₹75,000)
  • NPS self-contribution (additional ₹50,000 under 80CCD(1B))
  • Total deductions above ~₹3.75 lakh

Choose New Regime if you:

  • Have limited deductions (no home loan, low 80C)
  • Are a first-time earner or early career professional
  • Have salary income up to ₹12.75 lakh (NIL tax)
  • Prefer simpler compliance without proof submissions
  • Have employer NPS contribution (80CCD(2) — still available)
  • Total deductions below ~₹3.75 lakh
The Break-Even Rule of Thumb

The New Regime saves more tax when total eligible deductions are below ₹3.75 lakh. Above that, the Old Regime typically wins. But the exact number varies by income level — always run both through the calculator above for your specific situation. Salaried employees can decide which regime to use at ITR filing time, even if they declared a different regime to their employer.

Frequently Asked Questions

Which tax regime is better for FY 2025-26?
The New Regime is better when total deductions are below ~₹3.75 lakh. The Old Regime wins when you have a home loan (₹2L interest), full 80C (₹1.5L), NPS (₹50K), and 80D health insurance (₹75K) — combined ₹5.25 lakh in deductions. Use the calculator above to find out exactly for your numbers.
What is the income tax slab under New Regime FY 2025-26?
New Regime slabs for FY 2025-26: NIL up to ₹4L, 5% from ₹4-8L, 10% from ₹8-12L, 15% from ₹12-16L, 20% from ₹16-20L, 25% from ₹20-24L, 30% above ₹24L. The 87A rebate makes income up to ₹12 lakh tax-free for residents. Salaried employees get an additional ₹75,000 standard deduction, making gross salary up to ₹12.75 lakh effectively tax-free.
Is there NIL tax up to ₹12 lakh under the New Regime?
Yes — the Section 87A rebate provides NIL tax for resident individuals with total income up to ₹12 lakh under the New Regime. For salaried individuals, adding the ₹75,000 standard deduction means NIL tax up to ₹12.75 lakh gross salary. Important: this is an all-or-nothing cliff — income of ₹12,00,001 loses the entire rebate and ₹80,000 tax becomes payable. The rebate is NOT available to NRIs.
Can I switch between Old and New Tax Regime every year?
Salaried individuals and those without business income can switch between regimes every year at ITR filing time. If you declared Old Regime to your employer (for TDS purposes) but New Regime saves more, you can switch at filing. Those with business/professional income can only switch from New to Old Regime once in a lifetime — choose carefully.
