Every year, millions of Indian taxpayers face the same question: should I choose the new tax regime or the old one? The answer depends entirely on how many deductions you can claim. This guide gives you a clear framework to decide.
New Tax Regime - Lower Rates, Fewer Deductions
The new regime (default since FY 2023-24) offers lower tax slab rates. Income up to ₹12 lakh is effectively tax-free thanks to the Section 87A rebate. However, most deductions like 80C, 80D, HRA, and home loan interest are not available.
Old Tax Regime - Higher Rates, All Deductions
The old regime has higher base rates but allows you to claim all deductions - 80C (₹1.5L), 80D (health insurance), HRA, LTA, home loan interest (₹2L), NPS (₹50K), and more. You must actively opt-in to the old regime.
Side-by-Side Slab Comparison
| Income Slab | New Regime Rate | Old Regime Rate |
|---|---|---|
| Up to ₹3,00,000 | Nil | Nil |
| ₹3L - ₹4L | 5% | 5% (₹2.5L-₹5L) |
| ₹4L - ₹5L | 5% | 5% |
| ₹5L - ₹7L | 10% | 20% (₹5L-₹10L) |
| ₹7L - ₹10L | 10% | 20% |
| ₹10L - ₹12L | 15% | 30% |
| ₹12L - ₹15L | 20% | 30% |
| Above ₹15L | 30% | 30% |
Break-Even Analysis - When Does Old Regime Win?
Income Below ₹12 Lakh
New regime always wins. With the 87A rebate, income up to ₹12L is tax-free. Even ₹12.75L is effectively tax-free after the ₹75K standard deduction. No amount of deductions in the old regime can beat zero tax.
Income ₹12L - ₹15 Lakh
New regime usually wins unless your total deductions exceed ₹3-4 lakh. You would need significant HRA, full 80C (₹1.5L), health insurance (80D), and possibly NPS to make old regime worthwhile.
Income ₹15L - ₹20 Lakh
Old regime starts becoming competitive if you have ₹4-5L+ in total deductions. This is common for people paying rent in metros (high HRA) with home loans and health insurance.
Income Above ₹20 Lakh
Depends heavily on individual deductions. The 30% rate kicks in at ₹15L in new regime vs ₹10L in old regime, but old regime allows many more deductions. Calculate both to decide.

🏠Can You Switch Every Year?
Salaried employees: Yes, you can switch between old and new regime every financial year. Inform your employer at the start of the year, or choose when filing your ITR.
Business/professional income: You can switch from new to old only once. After that, the choice is permanent.
Common Mistake to Avoid
The most common mistake is choosing the old regime without actually having enough deductions. Many people assume old regime is always better because they have heard about 80C and HRA. But if your total deductions are under ₹2-3 lakh, the new regime with its lower slab rates and ₹75K standard deduction is almost certainly better. Always calculate both before deciding.
