New Tax Regime vs Old Tax Regime: Complete Comparison Guide FY 2025-26
Should you choose the new tax regime or stick with the old one? This guide compares both regimes with real examples so you can decide confidently.
What changed in the new tax regime for FY 2025-26?
The Union Budget 2025 made the new tax regime more attractive. The basic exemption was raised to ₹3 lakh, the rebate under Section 87A was revised, and standard deduction of ₹75,000 was allowed. The new regime is now the default — taxpayers must explicitly opt for the old regime.
| Income Slab | New Regime Rate | Old Regime Rate |
|---|---|---|
| Up to ₹3,00,000 | Nil | Nil |
| ₹3,00,001 – ₹7,00,000 | 5% | 5% (up to ₹5L) |
| ₹7,00,001 – ₹10,00,000 | 10% | 20% |
| ₹10,00,001 – ₹12,00,000 | 15% | 20% |
| ₹12,00,001 – ₹15,00,000 | 20% | 30% |
| Above ₹15,00,000 | 30% | 30% |
Key deductions available in old regime but not new regime
The old regime allows over 70 deductions and exemptions. The most commonly used are:
- Section 80C — up to ₹1.5L (LIC, ELSS, PPF, EPF, home loan principal, school fees)
- Section 80D — health insurance premium up to ₹25,000 (₹50,000 for senior citizens)
- HRA exemption — calculated based on salary, HRA received and rent paid
- LTA — Leave Travel Allowance twice in 4 years
- Section 80E — interest on education loan
- Section 80TTA/80TTB — interest on savings accounts and FDs for seniors
- Standard deduction of ₹50,000 (also ₹75,000 in new regime from FY 2025-26)
- Interest on home loan (Section 24b) — up to ₹2L for self-occupied
When is the new regime better?
The new regime is better when your total deductions are low — typically when you don't have home loan interest, don't invest significantly in 80C instruments, and don't receive high HRA. For most salaried employees with gross income below ₹10L who don't have large deductions, the new regime saves tax.
- Low or no HRA (living with parents or own home)
- Gross deductions (80C + 80D + HRA) below ₹2-2.5 lakh
- No home loan or home loan recently taken (low interest component)
- Salaried employee preferring simplicity over tax optimisation
- Income above ₹15L with minimal deductions — new regime slabs are lower
When is the old regime better?
The old regime is worth choosing when your deductions are high enough to make total taxable income significantly lower under the old regime than new regime slabs.
- Large 80C investments (₹1.5L EPF + LIC + ELSS + PPF)
- High HRA — especially in metro cities like Mumbai, Delhi, Bengaluru
- Home loan with significant interest component (₹1.5-2L per year)
- Multiple deductions: 80D (family health insurance), education loan, NPS
- Combined deductions exceeding ₹3-4 lakh per year
How to calculate which regime saves more tax
The break-even analysis: if your total eligible deductions (80C + 80D + HRA + home loan interest + standard deduction) exceed the difference in slab rates, the old regime saves more. As a rule of thumb: if your deductions exceed ₹3.75L, the old regime is typically better for income up to ₹15L.
Can you switch between regimes every year?
Salaried employees with no business income can switch between old and new regime every year when filing their ITR. Individuals with business income can switch once from new to old but cannot switch back. Make your decision before the tax year ends, not after.
