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 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.
