Since the New Tax Regime became the default regime from FY2023-24, the question every Indian taxpayer asks has become even more urgent: Should I stick with the new regime or opt for the old one?

The honest answer is: it depends on your income and deductions. But after working with hundreds of individual clients, we've built a clear framework that helps most people decide in minutes.

Understanding the Two Regimes

New Tax Regime — Slabs for FY2024-25

💰 New Regime Tax Slabs

₹0 – ₹3,00,000 → Nil
₹3,00,001 – ₹7,00,000 → 5%
₹7,00,001 – ₹10,00,000 → 10%
₹10,00,001 – ₹12,00,000 → 15%
₹12,00,001 – ₹15,00,000 → 20%
Above ₹15,00,000 → 30%

Rebate u/s 87A: Tax fully rebated if total income ≤ ₹7,00,000
Standard Deduction: ₹75,000 for salaried (from FY2024-25)

Old Tax Regime — Slabs for FY2024-25

💰 Old Regime Tax Slabs

₹0 – ₹2,50,000 → Nil
₹2,50,001 – ₹5,00,000 → 5%
₹5,00,001 – ₹10,00,000 → 20%
Above ₹10,00,000 → 30%

Rebate u/s 87A: Tax fully rebated if total income ≤ ₹5,00,000
Standard Deduction: ₹50,000 for salaried

The Deductions You Give Up in the New Regime

The new regime's lower slabs come at a cost — most popular deductions are not available:

  • ❌ Section 80C (₹1.5L) — PF, ELSS, PPF, LIC, school fees, home loan principal
  • ❌ Section 80D — Health insurance premiums
  • ❌ HRA exemption
  • ❌ LTA (Leave Travel Allowance)
  • ❌ Section 24(b) — Home loan interest (beyond employer benefit)
  • ❌ Section 80TTA/TTB — Savings interest deduction

What is available in the new regime:

  • ✅ Standard Deduction of ₹75,000 (enhanced in FY2024-25)
  • ✅ Section 80CCD(2) — Employer's NPS contribution (up to 14% of salary)
  • ✅ Family pension deduction
  • ✅ Section 80CCH — Agnipath scheme contributions

The Break-Even Point: When Does Old Regime Win?

The key question is: how much do your total deductions need to be for the old regime to save you more tax?

Based on our analysis of thousands of returns, here's a rough guide:

  • Income ₹7–10L: Old regime wins if total deductions exceed ~₹2.5L
  • Income ₹10–15L: Old regime wins if total deductions exceed ~₹3.75L
  • Income above ₹15L: Old regime wins if total deductions exceed ~₹4.5L
Most salaried employees with home loans, PF, LIC, and health insurance will find the old regime saving them ₹30,000–₹1,20,000 per year — even after the new regime's lower slabs.

Real-World Example: Arjun, 32, Software Engineer, ₹18L CTC

Let's walk through a real example. Arjun earns ₹18 lakhs CTC. His deductions:

  • 80C: ₹1,50,000 (ELSS + PF employee contribution)
  • 80D: ₹25,000 (health insurance)
  • Section 24(b): ₹2,00,000 (home loan interest)
  • HRA exemption: ₹1,20,000

Total deductions in old regime: ₹4,95,000
After deductions, taxable income: ~₹12,55,000

Old regime tax: ~₹2,08,250
New regime tax: ~₹2,62,500

Arjun saves ₹54,250 per year by staying in the old regime.

Who Should Switch to the New Regime?

The new regime genuinely wins for:

  • Individuals with very few investments or deductions
  • Young earners below ₹7L (effectively zero tax in new regime)
  • Self-employed with limited 80C investments
  • Those with low or no home loan interest

How to Choose — Our Recommendation
