India has two income tax regimes. The new regime has lower rates but allows very few deductions. The old regime has higher rates but lets you reduce tax through deductions like 80C, 80D, HRA and home loan interest. Which one saves more depends on how much you can actually claim.
New Regime Slabs
| Taxable income | Tax rate |
|---|---|
| Up to Rs 4,00,000 | Nil |
| Rs 4,00,001 to Rs 8,00,000 | 5% |
| Rs 8,00,001 to Rs 12,00,000 | 10% |
| Rs 12,00,001 to Rs 16,00,000 | 15% |
| Rs 16,00,001 to Rs 20,00,000 | 20% |
| Rs 20,00,001 to Rs 24,00,000 | 25% |
| Above Rs 24,00,000 | 30% |
The standard deduction is Rs 75,000 for salaried people. A section 87A rebate of up to Rs 60,000 applies if taxable income is up to Rs 12 lakh, so tax is zero up to that level (about Rs 12.75 lakh salary for a salaried person). Add 4% health and education cess on the tax.
Old Regime Slabs (below 60 years)
| Taxable income | Tax rate |
|---|---|
| Up to Rs 2,50,000 | Nil |
| Rs 2,50,001 to Rs 5,00,000 | 5% |
| Rs 5,00,001 to Rs 10,00,000 | 20% |
| Above Rs 10,00,000 | 30% |
The standard deduction is Rs 50,000. The rebate is Rs 12,500, so there is no tax if taxable income is up to Rs 5 lakh. Senior citizens get a higher basic exemption (Rs 3 lakh at 60+, Rs 5 lakh at 80+).
Deductions: What You Can Claim Where
| Deduction | Old regime | New regime |
|---|---|---|
| Standard deduction | Rs 50,000 | Rs 75,000 |
| 80C (PF, PPF, ELSS, LIC) up to Rs 1.5 lakh | Yes | No |
| 80D health insurance | Yes | No |
| HRA exemption | Yes | No |
| Home loan interest (self-occupied, up to Rs 2 lakh) | Yes | No |
| NPS 80CCD(1B) up to Rs 50,000 | Yes | No |
| Employer NPS 80CCD(2) | Yes | Yes |
Worked Example: Rs 15 Lakh Salary
Assume a salaried person with Rs 15,00,000 income. Tax below includes 4% cess and is calculated with the slabs above.
| Case | Taxable income | Approx. tax |
|---|---|---|
| New regime (no deductions except standard) | Rs 14,25,000 | Rs 97,500 |
| Old regime with only 80C (Rs 1.5 lakh) | Rs 13,00,000 | Rs 2,10,600 |
| Old regime with 80C, NPS Rs 50k, 80D Rs 25k and home loan interest Rs 2 lakh | Rs 10,25,000 | Rs 1,24,800 |
Even with heavy deductions the old regime costs more in this example. At higher deductions, such as a large HRA claim on top of the above, the gap can close. Your own numbers decide it.

Open Income Tax CalculatorHow to Decide in 4 Steps
Step 1: Add up your real deductions
Count only what you actually pay: 80C investments, health insurance, HRA, home loan interest and NPS.
Step 2: Calculate both regimes
Use the Income Tax Calculator with the same income for both.
Step 3: Compare the final tax
Pick the regime with the lower tax. If the difference is small, the simpler new regime may save you paperwork.
Step 4: Tell your employer and file correctly
Inform your employer of your choice for TDS, and select the same regime while filing your ITR. Keep your documents ready as PDFs, and use Compress PDF if a portal limits file size.
Common Mistakes
- Choosing a regime only because of last year's habit.
- Counting deductions that you have not actually invested in or paid.
- Forgetting that HRA and 80C do not work in the new regime.
- Ignoring surcharge and cess when comparing.
