Old vs New Tax Regime Calculator
Compare your tax liability under both regimes to make an informed decision
Comprehensive Guide: Old vs New Tax Regime Comparison (2024)
The Indian income tax system offers taxpayers a choice between two regimes: the old tax regime (with deductions and exemptions) and the new tax regime (with lower rates but fewer deductions). This guide will help you understand the differences, calculate which regime is better for you, and make an informed decision for your financial planning.
Key Differences Between Old and New Tax Regimes
| Feature | Old Tax Regime | New Tax Regime (Default from AY 2024-25) |
|---|---|---|
| Tax Slabs (Below 60) |
|
|
| Standard Deduction | ₹50,000 | ₹50,000 (from AY 2024-25) |
| Deductions (80C, 80D, etc.) | Allowed | Not allowed (except 80CCD(2) and 80JJAA) |
| HRA Exemption | Allowed | Not allowed |
| Rebate (87A) | ₹12,500 (if income ≤ ₹5L) | ₹25,000 (if income ≤ ₹7L) |
When to Choose the Old Tax Regime?
The old tax regime might be better if you:
- Have significant investments under Section 80C (PPF, ELSS, NSC, etc.)
- Pay high home loan interest (Section 24)
- Receive substantial HRA and pay rent
- Make charitable donations (Section 80G)
- Have education loan interest (Section 80E)
- Are in the 30% tax bracket with significant deductions
When to Choose the New Tax Regime?
The new tax regime might be better if you:
- Have minimal investments/deductions
- Are in the lower income brackets (below ₹15L)
- Prefer simpler tax filing without tracking investments
- Don’t own a house or pay rent (no HRA benefit)
- Are a salaried employee with standard deduction
Real-World Comparison: Which Regime Saves More?
Let’s compare with actual numbers for different income levels:
| Income (₹) | Old Regime Tax (₹) | New Regime Tax (₹) | Better Regime | Tax Saved (₹) |
|---|---|---|---|---|
| 5,00,000 | 12,500 | 0 | New | 12,500 |
| 7,50,000 | 37,500 | 25,000 | New | 12,500 |
| 10,00,000 | 75,000 | 45,000 | New | 30,000 |
| 15,00,000 | 1,87,500 | 90,000 | New | 97,500 |
| 20,00,000 | 3,07,500 | 1,80,000 | New | 1,27,500 |
| 10,00,000 (with ₹1.5L 80C + ₹50k HRA) | 45,000 | 45,000 | Both Equal | 0 |
Key Insight: For incomes below ₹15 lakhs, the new regime is generally better unless you have significant deductions. Above ₹15 lakhs, the old regime might be better if you can claim substantial deductions.

Frequently Asked Questions
1. Can I switch between regimes every year?
For salaried employees: You can choose the regime at the start of the financial year and must stick with it for that year. For business/profession income: You can switch every year, but once you opt out of the new regime, you cannot re-enter it.
2. Is the new regime really better for everyone?
No. While the new regime offers lower rates, it removes most deductions. If you have significant investments (₹1.5L+ in 80C), home loan, or HRA benefits, the old regime might still be better. Our calculator helps you determine which is optimal for your specific situation.
3. What is the standard deduction in the new regime?
From Assessment Year 2024-25, the new tax regime includes a standard deduction of ₹50,000 (same as old regime). This was introduced in Budget 2023 to make the new regime more attractive.
4. Can I claim both HRA and standard deduction?
No. In the old regime, you can claim HRA exemption instead of the standard deduction (whichever is higher). In the new regime, neither HRA nor standard deduction was initially available, but from AY 2024-25, the new regime includes the standard deduction.
5. How does the rebate under Section 87A work?
- Old Regime: Full rebate (₹12,500) if taxable income ≤ ₹5 lakhs
- New Regime: Full rebate (₹25,000) if taxable income ≤ ₹7 lakhs (from AY 2024-25)

Advanced Tax Planning Strategies
To optimize your tax liability regardless of the regime:
- Maximize 80C investments (₹1.5L limit) if using old regime:
- PPF (15-year lock-in, 7.1% interest)
- ELSS funds (3-year lock-in, market-linked returns)
- NSC (5-year lock-in, 7.7% interest)
- Life insurance premiums
- Tuition fees for children
- Utilize HRA exemption fully if paying rent:
- Minimum of: (a) Actual HRA received, (b) 50% of salary (metro) or 40% (non-metro), (c) Rent paid minus 10% of salary
- Requires rent receipts and landlord’s PAN if rent > ₹1L/year
- Optimize home loan benefits:
- Section 24: Up to ₹2L interest deduction (₹30k for let-out property)
- Section 80EEA: Additional ₹1.5L for affordable housing
- Principal repayment under 80C (₹1.5L limit)
- Health insurance for family:
- ₹25k for self/spouse/children (₹50k if senior citizen)
- Additional ₹25k for parents (₹50k if senior citizens)
- Preventive health check-up: ₹5k (within 80D limit)
- Consider NPS for additional deduction:
- ₹50k under Section 80CCD(1B) (over and above 80C)
- Employer contribution up to 10% of salary (14% for central govt)
Common Mistakes to Avoid
Avoid these pitfalls when choosing between tax regimes:
- Not calculating both options: Always compare both regimes using our calculator before deciding.
- Ignoring employer’s default choice: Many companies default to the new regime – check your Form 16.
- Overlooking state taxes: Some states have professional tax that applies regardless of regime.
- Forgetting to submit proof: For old regime, submit investment proofs to your employer by the deadline.
- Not considering future changes: Tax laws change annually – review your choice each financial year.
- Assuming new regime is always better: For high earners with significant deductions, the old regime may still be better.
Case Study: ₹12 Lakh Salary Comparison
Let’s examine a practical example for someone earning ₹12 lakhs annually:
| Parameter | Old Regime | New Regime |
|---|---|---|
| Gross Income | ₹12,00,000 | ₹12,00,000 |
| Standard Deduction | ₹50,000 | ₹50,000 |
| 80C Investments | ₹1,50,000 | Not allowed |
| HRA (₹60k received, ₹40k rent) | ₹48,000 | Not allowed |
| 80D (Medical Insurance) | ₹25,000 | Not allowed |
| Taxable Income | ₹9,27,000 | ₹11,50,000 |
| Tax Calculation |
|
|
| Better Regime | New Regime (saves ₹2,900) | |
Key Takeaway: Even with ₹2.25L in deductions, the new regime is slightly better in this case. However, if the deductions were higher (e.g., home loan interest), the old regime might win.
