Executive Summary
The Indian taxation landscape fundamentally shifted with the default adoption of the revised Section 115BAC New Tax Regime. With a higher standard deduction of ₹75,000and full rebate up to ₹7.75 Lakhs for salaried professionals, the New Regime is more advantageous for roughly 75% to 80% of taxpayers. However, if your cumulative deductions under Section 80C, Section 80D, HRA, and Home Loan Interest (Section 24b) exceed ₹3.75 Lakhs to ₹4.25 Lakhs, the Old Regime remains mathematically superior.
1. Revised New Tax Regime Slab Structure
Under Section 115BAC, tax rates are lower across successive brackets, but almost all traditional exemptions (Section 80C, 80D, HRA, LTA) are forgone. Salaried employees still retain the ₹75,000 standard deductionand employer NPS contributions under Section 80CCD(2).
| Annual Taxable Income Slab | New Regime Tax Rate |
|---|---|
| ₹0 – ₹3,00,000 | Nil (0%) |
| ₹3,00,001 – ₹7,00,000 | 5% (Eligible for 87A rebate up to ₹7L) |
| ₹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% |
* Plus 4% Health & Education Cess on computed tax. Surcharge applies for taxable income exceeding ₹50 Lakhs.
2. Old Tax Regime Slabs & Deduction Arsenal
The Old Regime features steeper slab jumps (reaching the top 30% rate at just ₹10 Lakhs of taxable income), but allows you to subtract numerous genuine expenses and investments from your gross income:
- Section 80C: Up to ₹1,50,000 (EPF, PPF, ELSS, Life Insurance, Home Loan Principal).
- Section 80D: Up to ₹25,000 (self/family) + up to ₹50,000 (senior citizen parents) for health insurance.
- House Rent Allowance (HRA): Partial or full exemption under Section 10(13A).
- Section 24(b): Up to ₹2,00,000 on home loan interest paid for self-occupied property.
- Standard Deduction: Flat ₹50,000 for salaried employees.
3. The Break-Even Calculation: When Does Old Beat New?
The critical financial question is: How many deductions do I need before the Old Regime saves more tax than the New Regime?
4. Which Regime Should You Pick? Decision Framework
Choose New Tax Regime If:
- Your annual gross salary is below ₹7.75 Lakhs (Tax is zero).
- You do not pay rent or own a home with a running housing loan.
- You prefer liquidity over locking money into 15-year PPF or 5-year tax-saving FDs.
- You want an effortless tax filing process without maintaining proof receipts for your HR portal.
Choose Old Tax Regime If:
- You pay significant house rent in metro cities (claiming high HRA exemption).
- You are servicing a home loan with annual interest payments of ₹2,00,000.
- You maximize Section 80C (₹1.5L) + Section 80D (₹50k–₹75k) + Section 80CCD(1B) NPS (₹50k).
- Your total eligible deductions exceed ₹3.75 Lakhs to ₹4.25 Lakhs.
