1. The two regimes at a glance
India offers two income tax regimes. You choose one each year when filing your return (salaried employees can switch annually; business owners have restrictions).
| Feature | Old Regime | New Regime |
|---|---|---|
| Standard deduction | ₹50,000 | ₹75,000 |
| 80C deductions | Yes (₹1.5L) | No |
| 80D health insurance | Yes | No |
| HRA exemption | Yes | No |
| Home loan interest | Yes (₹2L) | No |
| Rebate limit | ₹5L | ₹12L |
| Tax-free income (salaried) | ~₹5.5L | ~₹12.75L |
2. New Regime slabs (FY 2025-26)
| Income slab | Tax rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
💡 Under the New Regime, if your taxable income is up to ₹12 lakh, the entire tax is rebated under Section 87A. For salaried employees with the ₹75,000 standard deduction, this means gross income up to ₹12.75 lakh is effectively tax-free.
3. Old Regime slabs
| Income slab | Tax rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
Old Regime also offers a rebate up to ₹5 lakh (tax becomes zero) and allows all the deductions listed above.
4. Which regime is better for you?
The answer depends entirely on your income and deductions. Rough guidelines:
- Income up to ₹12.75L: New Regime almost always wins (tax-free).
- Income ₹12.75L–₹15L with few deductions: New Regime usually wins.
- Income ₹15L–₹20L with high deductions (₹3.5L+): Old Regime often wins.
- Income above ₹50L: New Regime may win due to 15% surcharge cap.
- Business owners with many deductions: Old Regime may still be better.

5. A worked example
Gross salary ₹12,00,000. Deductions: 80C ₹1.5L, 80D ₹25K, 80CCD(1B) ₹50K. Salaried.
Old Regime:
- Standard deduction: ₹50,000
- 80C + 80D + 80CCD(1B): ₹2,25,000
- Total deductions: ₹2,75,000
- Taxable income: ₹9,25,000
- Tax: ₹2,500 (5% on 2.5L–5L) + ₹85,000 (20% on 5L–9.25L) = ₹87,500
- + 4% cess = ₹91,000
New Regime:
- Standard deduction: ₹75,000
- Taxable income: ₹11,25,000
- Tax: ₹20,000 + ₹32,500 (10% on 8L–11.25L) = ₹52,500
- Rebate u/s 87A: ₹52,500 (fully rebated since taxable ≤ ₹12L)
- Tax payable: ₹0
Result: New Regime saves ₹91,000 — a huge win. This is why the New Regime is so attractive for income up to ₹12.75L.
6. Common mistakes
- Assuming Old Regime is always better: Not true since the 2025 New Regime rebate changes. Run the numbers.
- Forgetting the standard deduction: ₹75,000 under new regime makes a big difference.
- Ignoring the rebate: Under new regime, income up to ₹12L (₹12.75L salaried) has zero tax.
- Over-claiming deductions: False claims can trigger scrutiny and penalties.
- Not switching regimes: Salaried employees can switch every year — do so if it saves money.
- Forgetting cess: The 4% health and education cess applies to all tax and surcharge.
7. Final thoughts
The Old vs New Regime decision is one of the most impactful financial choices you make each year. For most salaried employees earning up to ₹12.75 lakh, the New Regime is a clear win. Above that, it depends on your deductions.
