Old vs New Tax Regime: Which One Should You Choose?#
Understanding Both Regimes#
India offers two tax regimes - the old regime with deductions and the new regime with lower rates but fewer deductions.
Old Tax Regime#
- Higher tax rates
- All deductions available (123, 126, HRA, etc.)
- Standard deduction: Rs 50,000
- Rebate under Section 156 only if taxable income is up to Rs 5 lakh
New Tax Regime (Default)#
- Lower tax rates
- Most deductions NOT available
- Standard deduction: Rs 75,000
- Rebate under Section 156 up to Rs 12 lakh taxable income (up to Rs 60,000 rebate)
- Made permanent from FY 2025-26
Tax Slab Comparison#
New Regime Slabs (FY 2026-27)#
| Income Range | Tax Rate |
|---|---|
| Up to Rs 4,00,000 | Nil |
| Rs 4,00,001 - Rs 8,00,000 | 5% |
| Rs 8,00,001 - Rs 12,00,000 | 10% |
| Rs 12,00,001 - Rs 16,00,000 | 15% |
| Rs 16,00,001 - Rs 20,00,000 | 20% |
| Rs 20,00,001 - Rs 24,00,000 | 25% |
| Above Rs 24,00,000 | 30% |
Old Regime Slabs — Below 60 Years (FY 2026-27)#
| Income Range | Tax Rate |
|---|---|
| Up to Rs 2,50,000 | Nil |
| Rs 2,50,001 - Rs 5,00,000 | 5% |
| Rs 5,00,001 - Rs 10,00,000 | 20% |
| Above Rs 10,00,000 | 30% |
Senior citizens (60-80) and super senior citizens (80+) get a higher Nil band under the old regime — Rs 3 lakh and Rs 5 lakh respectively — but the new regime applies the same slabs to everyone regardless of age.
When to Choose Old Regime#
Choose old regime if your total deductions exceed Rs 1.5 lakh:
- Section 123 investments (PPF, ELSS, LIC): Rs 1.5 lakh
- Section 126 (Health Insurance): Rs 25,000-50,000
- HRA exemption: Rs 50,000-1.5 lakh
- Home loan interest: Rs 2 lakh
- Other deductions: Rs 20,000-50,000
Total potential deductions: Rs 3-4 lakh
When to Choose New Regime#
Choose new regime if:
- You have minimal investments
- Your total deductions are less than Rs 1.5 lakh
- You want simpler tax filing
- You prefer predictable tax liability
Example Calculations#
Scenario 1: Salaried Employee (Significant Deductions)
Income Details:
- Basic Salary: Rs 1,00,000/month
- HRA: Rs 30,000/month
- Special Allowance: Rs 20,000/month
- Total Annual Income: Rs 18,00,000
Deductions Available (Old Regime):
- Standard Deduction: Rs 50,000
- Section 123: Rs 1,50,000
- Section 126: Rs 25,000
- HRA: Rs 1,20,000
- Total deductions: Rs 3,45,000 — taxable income Rs 14,55,000
Deductions Available (New Regime):
- Standard Deduction: Rs 75,000 (Section 123, Section 126, and HRA are not available)
- Taxable income: Rs 17,25,000
Old Regime Tax: Rs 2,49,000 + 4% cess = approximately Rs 2,58,960
New Regime Tax: Rs 1,45,000 + 4% cess = approximately Rs 1,50,800 (taxable income exceeds the Rs 12 lakh Section 156 rebate ceiling, so no rebate applies)
Verdict: New regime saves approximately Rs 1,08,000 — even with Rs 3.45 lakh of old-regime deductions, the wider new-regime slabs and higher standard deduction outperform it at this income level. Recalculate with your own numbers before deciding; a Rs 1-2 lakh swing in deductions can change the verdict.
Scenario 2: Minimal Deductions
Income Details:
- Total Annual Income: Rs 8,00,000
Old Regime: Standard Deduction Rs 50,000 — taxable income Rs 7,50,000
New Regime: Standard Deduction Rs 75,000 — taxable income Rs 7,25,000
Old Regime Tax: Rs 62,500 + 4% cess = Rs 65,000 (taxable income exceeds the Rs 5 lakh old-regime rebate ceiling)
New Regime Tax: Rs 0 — taxable income is within the Rs 12 lakh Section 156 rebate ceiling, so the full Rs 16,250 computed tax is rebated
Verdict: New regime saves approximately Rs 65,000

How to Switch Regimes#
- You can choose regime at the time of ITR filing
- No need to intimate employer separately
- Even if employer deducted TDS under old regime, you can file under new regime
Points to Consider#
- Calculate both tax liabilities before deciding
- Consider future deductions (home loan, insurance)
- Review your investment portfolio
- Consult a Chartered Accountant for advice specific to your situation
The new regime is simpler but may cost more if you have significant deductions. Choose wisely based on your specific situation.
