Old vs New Tax Regime 2026: Which One Saves You More?
1. Introduction
Every salaried Indian faces the same question at the start of every financial year: Old Tax Regime or New Tax Regime? With the Union Budget 2025-26 making the New Regime even more attractive — raising the basic exemption limit to ₹4 lakh and restructuring slabs — the choice has never been more important. This guide breaks down both regimes, compares them side-by-side, and helps you decide which one puts more money in your pocket for FY 2025-26 (AY 2026-27).
2. Old Tax Regime
The Old Tax Regime has been the default system for Indian taxpayers for decades. Its key feature is a rich set of deductions and exemptions that can significantly reduce your taxable income if you invest and plan well.
Key deductions available:
- Section 80C – Up to ₹1.5 lakh (PPF, ELSS, LIC, home loan principal, etc.)
- Section 80D – Health insurance premium up to ₹25,000 (₹50,000 for senior citizens)
- HRA Exemption – House Rent Allowance for salaried employees in rented accommodation
- Section 24(b) – Home loan interest up to ₹2 lakh
- Standard Deduction – ₹50,000 for salaried individuals
- NPS (80CCD) – Additional ₹50,000 over the 80C limit
Old Regime slabs (FY 2025-26): 0% up to ₹2.5L · 5% (₹2.5L–₹5L) · 20% (₹5L–₹10L) · 30% above ₹10L. A rebate under Section 87A makes income up to ₹5L effectively tax-free.
3. New Tax Regime (Default from FY 2024-25)
Introduced in Budget 2020 and made the default regime from FY 2023-24, the New Tax Regime offers lower slab rates in exchange for forgoing most deductions and exemptions.
Revised slabs for FY 2025-26:
- 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, income up to ₹12 lakh is effectively tax-free for resident individuals (after the enhanced Section 87A rebate of ₹60,000). The standard deduction of ₹75,000 is also available, making the effective zero-tax threshold ₹12.75 lakh for salaried taxpayers.
4. Comparison Table
| Feature | Old Regime | New Regime |
|---|---|---|
| Basic Exemption | ₹2.5 Lakh | ₹4 Lakh |
| 80C Deduction | ✅ Up to ₹1.5L | ❌ Not available |
| HRA Exemption | ✅ Available | ❌ Not available |
| Standard Deduction | ₹50,000 | ₹75,000 |
| Section 87A Rebate | Up to ₹5L income | Up to ₹12L income |
| Home Loan Interest (24b) | ✅ Up to ₹2L | ❌ Not available |
| Best suited for | High deduction earners | Most salaried taxpayers |
5. Which One is Better?
The answer depends on your total deductions. Here is a practical rule of thumb for FY 2025-26:
- Income up to ₹12.75 lakh? → New Regime is almost always better (zero tax after rebate + standard deduction).
- Income ₹12.75L–₹18L with large deductions? → Run both calculations. Old Regime can win if 80C + HRA + 80D together exceed ₹4–5 lakh.
- Income above ₹18L with heavy investments? → Old Regime often saves more if deductions exceed ₹5.5L+.
- No investments or renting without HRA? → New Regime will almost always be cheaper.

6. Frequently Asked Questions
Can I switch regimes every year?
Salaried individuals (without business income) can switch between regimes every financial year. Those with business income can switch only once — from New to Old — and cannot switch back.
Is NPS deduction available in the New Regime?
The employer's contribution to NPS (Section 80CCD(2)) is still available as a deduction in the New Regime. The employee's own contribution under 80CCD(1B) is not.
What happens if I don't choose a regime?
From FY 2023-24 onward, the New Tax Regime is the default. If you do not submit Form 10-IEA, your employer will deduct TDS under the New Regime automatically.
Which regime is better for a ₹10 lakh salary?
For a ₹10 lakh gross salary, the New Regime typically results in zero or very low tax after the ₹60,000 rebate and ₹75,000 standard deduction. The Old Regime may save slightly more only if you have ₹1.5L in 80C + significant HRA + 80D deductions.
7. Conclusion
The New Tax Regime 2026 is a strong default choice for most Indian salaried employees — especially those earning up to ₹12.75 lakh or those with limited deductions. For higher earners with substantial investments, HRA, and home loans, the Old Regime may still offer meaningful tax savings.
