Tax Slabs Comparison
New Tax Regime (Default from FY 2023-24)
Old Tax Regime
Key Differences
When to Choose New Regime?
- You have minimal tax-saving investments
- You don't pay rent or have HRA exemption
- You don't have home loan for self-occupied property
- Your total deductions are less than ₹3-4 lakhs
- You want simplicity without investment planning
When to Choose Old Regime?
- You have significant 80C investments (EPF, PPF, ELSS, etc.)
- You pay rent and claim HRA exemption
- You have home loan interest deduction
- You have high health insurance premiums (80D)
- Your total deductions exceed ₹3.75 lakhs (approximate break-even)
Break-even Analysis
The break-even point depends on your income level. As a rough guide:
Important Points
- Default Regime: New regime is default from FY 2023-24
- Switching: Salaried can switch every year. Business income has restrictions.
- Form 10IE: Not required for salaried if employer handles it
- Employer NPS: 80CCD(2) is available in BOTH regimes
- Gratuity/Leave Encashment: Exemptions available in BOTH regimes
Practical example
A taxpayer with salary income and only limited deductions may find that the new regime produces a lower tax result because the lower slab rates outweigh the missing old regime benefits. A taxpayer with HRA, strong 80C usage, mediclaim deduction, and eligible home-loan interest may see the opposite result.
Common mistakes
- Comparing regimes without matching the same income base
- Including deductions in the new regime that are not available there
- Ignoring HRA, home-loan interest, or employer NPS details during comparison
- Relying on old-year slab assumptions for a current-year decision
- Assuming the default payroll choice is always the best filing choice
Frequently Asked Questions

The old regime becomes more attractive when you can actually use meaningful deductions or exemptions such as HRA, 80C, 80D, or eligible home-loan interest.
