Decision Framework: Which Regime to Choose?

Choose New Regime If:

✅ Your total deductions are less than ₹2.5 lakh ✅ You don't have a home loan ✅ You don't receive HRA ✅ You prefer simplicity over tax planning ✅ Your income is between ₹5-10 lakh with minimal investments

Choose Old Regime If:

✅ Your total deductions exceed ₹2.5 lakh ✅ You have a home loan with significant interest payment ✅ You receive HRA and live in a rented house ✅ You actively invest in tax-saving instruments ✅ Your income is above ₹12 lakh with multiple deductions

Common Mistakes to Avoid

1. Not Calculating Both Options

Many people stick to one regime without calculating their actual tax liability under both. Always run the numbers!

2. Ignoring Future Deductions

If you're planning to buy a house or increase investments, factor that into your decision.

3. Forgetting About Employer's NPS

Employer's contribution to NPS is allowed in both regimes - don't miss this!

4. Not Reviewing Annually

Your financial situation changes. Review your choice every year.
