Every financial year, millions of salaried employees and business owners across India face the crucial choice: Should I choose the Old Tax Regime or the New Tax Regime?
With the Union Budget expanding standard deductions and widening the income slabs under the default New Tax Regime, many taxpayers are confused about whether their Section 80C, 80D, and HRA deductions still justify staying in the Old Regime.
In this detailed financial analysis, we compare both regimes side by side, provide the exact mathematical breakeven formula, and show you how to calculate your net liability using our Income Tax Calculator.
Income Tax Slabs Comparison (FY 2025-26 / AY 2026-27)
#### New Tax Regime (Default Regime):
- Up to ₹3,00,000: NIL
- ₹3,00,001 to ₹7,00,000: 5%
- ₹7,00,001 to ₹10,00,000: 10%
- ₹10,00,001 to ₹12,00,000: 15%
- ₹12,00,001 to ₹15,00,000: 20%
- Above ₹15,00,000: 30%
(Salaried standard deduction: ₹75,000; Section 87A rebate covers taxable income up to ₹7,00,000, making salary income up to ₹7,75,000 effectively tax-free!)
#### Old Tax Regime (Optional):
- Up to ₹2,50,000: NIL
- ₹2,50,001 to ₹5,00,000: 5%
- ₹5,00,001 to ₹10,00,000: 20%

(Salaried standard deduction: ₹50,000; permits deductions under 80C, 80D, HRA, home loan interest under Sec 24b).
Head-to-Head Comparison Table: Total Tax Payable
Below is a direct comparison of tax payable across common gross annual salary levels:
| Gross Annual Salary | Old Regime (Standard 80C ₹1.5L + 80D ₹25K + Std Ded) | New Tax Regime (Std Ded ₹75K) | Better Regime |
|---|---|---|---|
| ₹7,50,000 | ₹28,600 | ₹0 (Rebate 87A applies) | New Regime (Save ₹28,600) |
| ₹10,00,000 | ₹70,200 | ₹44,200 | New Regime (Save ₹26,000) |
| ₹12,50,000 | ₹1,22,200 | ₹80,600 | New Regime (Save ₹41,600) |
| ₹15,00,000 | ₹1,74,200 | ₹1,24,800 | New Regime (Save ₹49,400) |
| ₹20,00,000 | ₹3,04,200 | ₹2,65,200 | New Regime (Save ₹39,000) |
The Breakeven Deduction Formula: When Does Old Regime Win?
The Old Regime is only beneficial if your total eligible deductions (Standard Deduction + 80C + 80D + HRA + Home Loan Interest Section 24b) exceed the critical breakeven point:
- For Gross Salary of ₹10 Lakh: Breakeven deductions required = ₹3.25 Lakh
- For Gross Salary of ₹15 Lakh: Breakeven deductions required = ₹4.00 Lakh
- For Gross Salary of ₹20 Lakh: Breakeven deductions required = ₹4.25 Lakh
If you do NOT pay substantial house rent (HRA) or heavy home loan interest, the New Tax Regime is mathematically superior for the vast majority of taxpayers.
