5. Old Regime vs New Regime: Which is Better?
The choice between old and new regimes depends on your income level and ability to claim deductions. Here’s a quick comparison:
| Feature | Old Regime | New Regime (Default) |
|---|---|---|
| Tax Slabs | 3 slabs (5%, 20%, 30%) | 6 slabs (0% to 30%) |
| Standard Deduction | ₹50,000 | ₹50,000 |
| Section 80C Deduction | ✅ Up to ₹1.5L | ❌ Not available |
| HRA Exemption | ✅ Available | ❌ Not available |
| Home Loan Benefits | ✅ Full benefits | ❌ Limited benefits |
| Rebate u/s 87A | Up to ₹12,500 (income ≤ ₹5L) | Up to ₹25,000 (income ≤ ₹7L) |
| Best for | High deductions (HRA, home loan, investments) | Lower income, fewer deductions |
According to Income Tax Department data, about 63% of taxpayers still opt for the old regime due to substantial savings from deductions, especially for those with home loans or significant HRA benefits.
6. Common Mistakes to Avoid
- Not claiming HRA properly: Many taxpayers don’t claim the full HRA exemption they’re entitled to. Remember it’s the minimum of:
- Actual HRA received
- 50% of salary (40% for non-metros)
- Rent paid minus 10% of salary
- Missing Section 80D benefits: The additional ₹25,000 deduction for senior citizen parents is often overlooked.
- Incorrect home loan claims: Many claim the entire EMI as deduction instead of separating principal (80C) and interest (24).
- Not submitting proof: For claimed deductions, always maintain proper documentation as the IT department may ask for proofs during assessment.
- Ignoring surcharge thresholds: The surcharge kicks in at ₹50 lakh, not just at ₹1 crore as many believe.
7. When to Choose Old Regime Over New Regime
You should opt for the old regime if:
- You have significant home loan (both principal and interest components)
- You live in a rented accommodation and can claim HRA
- You make substantial investments under 80C (PPF, ELSS, etc.)
- You have high medical expenses that qualify for 80D deductions
- Your total deductions exceed ₹2.5 lakh annually
- You’re a senior citizen with income between ₹5-10 lakh
According to a Reserve Bank of India report, taxpayers with home loans save an average of ₹45,000-₹75,000 annually by staying in the old regime compared to the new one.
8. Recent Changes and Updates
