New vs Old Tax Regime 2025-26: Which is Better? Full Comparison
New vs old tax regime comparison for FY 2025-26. Find out which regime saves more tax with a full breakdown of slabs, deductions, and who should choose which option.
The single most debated personal finance question in India since 2020 has been: “Should I choose the New Tax Regime or stick with the Old Tax Regime?” As of FY 2025-26, the government has doubled down on making the New Regime the default, significantly sweetening it with enhanced slabs and a higher standard deduction. Yet, for taxpayers with significant investments and deductions, the Old Regime may still win. Let’s break it down completely.
New Tax Regime vs Old Tax Regime: 2025-26 Slabs
New Tax Regime Slabs (FY 2025-26)
The new regime received a major facelift in Budget 2024, which took effect from FY 2024-25 and continues in 2025-26.
| Annual Income | 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% |
Rebate u/s 87A: If your income is up to ₹12 Lakhs, the entire tax is waived under Section 87A. This means individuals earning up to ₹12 Lakhs have a zero income tax liability under the new regime (before cess).
Standard Deduction: ₹75,000 is available to salaried employees and pensioners under the new regime.
Old Tax Regime Slabs (FY 2025-26)
The old regime retains the traditional slab structure:
| Annual Income | Tax Rate (Below 60 years) |
|---|---|
| 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% |
Rebate u/s 87A: If your income (after all deductions) is up to ₹5 Lakhs, the tax is fully rebated.
Standard Deduction: ₹50,000 (lower than the new regime).
Key Deductions Available Under Old Regime (Not in New Regime)
The old regime’s competitive advantage lies entirely in the deductions it allows. Here are the most impactful ones:
| Section | Deduction | Limit |
|---|---|---|
| 80C | ELSS, PPF, LIC, EPF, home loan principal, tuition fees | ₹1,50,000 |
| 80D | Health insurance premiums | Up to ₹75,000 (with parents) |
| 80CCD(1B) | NPS additional contribution | ₹50,000 |
| 24(b) | Home loan interest (self-occupied) | ₹2,00,000 |
| HRA | House Rent Allowance (salaried) | Actual/Calculated |
| LTA | Leave Travel Allowance | Actual travel costs |
| 80TTA | Savings bank interest | ₹10,000 |
A taxpayer who maximizes all these deductions can reduce their taxable income by as much as ₹5-6 Lakhs from their gross income.
Comparison: Who Benefits from Which Regime?
Example 1: Salaried Professional, ₹12 Lakh Gross Income
| New Regime | Old Regime | |
|---|---|---|
| Gross Income | ₹12,00,000 | ₹12,00,000 |
| Standard Deduction | ₹75,000 | ₹50,000 |
| 80C (PPF, ELSS, etc.) | — | ₹1,50,000 |
| 80D (Health Insurance) | — | ₹25,000 |
| Taxable Income | ₹11,25,000 | ₹9,75,000 |
| Tax on Taxable Income | ₹62,500 (but income ≤ 12L → ₹0 via rebate) | ₹1,00,000 |
| Net Tax (+ 4% Cess) | ₹0 | ₹1,04,000 |
Winner: New Regime (₹1,04,000 saved)
Example 2: Salaried with Aggressive Investments, ₹20 Lakh Income
| New Regime | Old Regime | |
|---|---|---|
| Gross Income | ₹20,00,000 | ₹20,00,000 |
| Standard Deduction | ₹75,000 | ₹50,000 |
| 80C | — | ₹1,50,000 |
| 80D | — | ₹25,000 |
| HRA Exemption | — | ₹1,20,000 |
| Home Loan Interest | — | ₹2,00,000 |
| 80CCD(1B) NPS | — | ₹50,000 |
| Taxable Income | ₹19,25,000 | ₹14,05,000 |
| Net Tax (+ 4% Cess) | ₹2,56,230 | ₹2,32,440 |
Winner: Old Regime (₹23,790 saved)
The Break-Even Point
The general rule of thumb:
- If your deductions under the old regime exceed ~₹3.75 Lakhs, the old regime likely wins for incomes above ₹12 Lakhs.
- If your deductions are minimal (mostly just 80C), the new regime is almost always better.
What Changed in 2025-26?
The major change introduced in Budget 2024 (taking full effect in 2025-26) was:
- The Section 87A rebate threshold increased to ₹12 Lakhs (from ₹7 Lakhs).
- The basic exemption limit increased to ₹4 Lakhs (from ₹3 Lakhs).
- Standard deduction for salaried increased to ₹75,000 (from ₹50,000).
These changes have significantly tilted the balance for middle-class salaried taxpayers towards the new regime.
Who Should Choose What?
Choose New Regime if:
- Your income is up to ₹12 Lakhs (zero tax!)
- You don’t have a home loan on a self-occupied property
- You haven’t maximized 80C, NPS, or health insurance
- You are young and your investment portfolio is mainly market-linked (ELSS already in new regime? No — 80C deduction is gone in new regime)
- You are a freelancer or self-employed with minimal deductions
Choose Old Regime if:
- You have a substantial home loan with high interest outgo
- You pay significant HRA in a metro city
- You are 50+, have high health insurance premiums for self and senior parents
- You aggressively invest in NPS under 80CCD(1B) for the additional ₹50,000 deduction
How to Switch Between Regimes
Salaried employees can switch between the old and new regime every financial year at the time of filing their ITR. However, during the year, they must inform their employer at the beginning of the year so that the employer can calculate TDS accordingly.
Businesses and professionals with income from business or profession can only switch once — from old to new or new to old. Once they have switched back to the old regime, they cannot switch again to the new regime (except in specific circumstances).
Conclusion
The new tax regime is undeniably attractive for the majority of Indian middle-class taxpayers, especially those earning up to ₹12 Lakhs. However, for high earners with significant financial commitments (home loans, insurance, NPS), the old regime’s deductions can still deliver substantial savings. Always run the numbers for your specific situation before deciding, and consider consulting a CA for personalized advice.
