Old Regime vs New Regime: Which Is Better for You in FY 2025-26?
A clear, numbers-first guide to choosing between the old and new income tax regimes for FY 2025-26. Includes worked examples for different income levels and deduction amounts.
Every year after the Budget, one question floods personal finance forums across India: "Should I switch to the new regime?" For FY 2025-26, the answer depends entirely on how much you can claim in deductions under the old regime. This guide walks you through the logic, the numbers, and the breakeven point — so you can make the choice that actually saves you more tax.
What changed in FY 2025-26
The new regime is now the default — if you do nothing, you are automatically placed in it. The key changes that make FY 2025-26 different from earlier years:
- Standard deduction raised to ₹75,000 under the new regime (was ₹50,000 in FY 2023-24, same ₹75,000 continues from FY 2024-25).
- Section 87A rebate raised to ₹60,000, making income up to ₹12,00,000 completely tax-free for most individuals under the new regime.
- New regime slabs were restructured in Budget 2024: 0% up to ₹4L, 5% from ₹4–8L, 10% from ₹8–12L, 15% from ₹12–16L, 20% from ₹16–20L, 25% from ₹20–24L, 30% above ₹24L.
New regime: slab rates at a glance
| Income band | Tax rate |
|---|---|
| Up to ₹4,00,000 | 0% |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |

| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Plus a ₹75,000 standard deduction for salaried individuals. The Section 87A rebate (up to ₹60,000) eliminates tax entirely if taxable income is ₹12L or below. A 4% health and education cess applies on the final tax.
Old regime: slab rates at a glance
| Income band (below 60) | Tax rate |
|---|---|
| Up to ₹2,50,000 | 0% |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
₹50,000 standard deduction for salaried individuals. Section 87A rebate covers taxable income up to ₹5,00,000. Full deductions under 80C, 80D, HRA, home loan interest are available.
The real question: what is your breakeven deduction?
The old regime only wins if your total deductions (standard deduction + 80C + 80D + HRA + home loan interest + others) are large enough to bring your taxable income below what the new regime taxes. The breakeven amount depends on your gross income.
As a rough rule of thumb for a salaried individual:
- Income ₹8–12L: The new regime is almost always better unless you have very high deductions. The 87A rebate makes the new regime effectively zero-tax up to ₹12L — hard to beat.
- Income ₹12–20L: The crossover happens around ₹3.5–4.5L in total deductions. If you max out 80C (₹1.5L), have a home loan interest claim of ₹2L under 24(b), and pay HRA, the old regime often wins.
- Income above ₹20L: The old regime's 30% slab hits earlier, but large deductions — especially home loan interest + 80C + 80D — can still make it competitive. Run the numbers both ways.
Worked example: ₹15 lakh salary
Suppose you earn ₹15,00,000 gross. You have ₹1,50,000 in 80C investments (ELSS, PPF), ₹25,000 in health insurance (80D), and ₹1,50,000 in home loan interest (24b).
New regime:
- Taxable income: ₹15,00,000 − ₹75,000 (SD) = ₹14,25,000
- Slab tax: ₹20,000 + ₹40,000 + ₹33,750 = ₹93,750
- Cess (4%): ₹3,750
- Total: ₹97,500
Old regime:
- Deductions: ₹50,000 (SD) + ₹1,50,000 (80C) + ₹25,000 (80D) + ₹1,50,000 (24b) = ₹3,75,000
- Taxable income: ₹15,00,000 − ₹3,75,000 = ₹11,25,000
- Slab tax: ₹12,500 + ₹1,00,000 + ₹37,500 = ₹1,50,000
- Cess (4%): ₹6,000
- Total: ₹1,56,000
In this case, the new regime saves ₹58,500. The old regime only wins here if deductions were considerably higher — for example, if HRA exemption or a larger home loan interest claim were added.
Who should choose the old regime?
The old regime tends to work better for people who:
- Pay rent in a metro and claim large HRA exemptions
- Have a home loan with interest above ₹2L per year
- Consistently max out 80C (PPF, ELSS, life insurance, home loan principal)
- Have significant 80D premiums (family floater health insurance for parents)
- Have NPS contributions and claim the additional 80CCD(1B) deduction (₹50,000)
Who should choose the new regime?
The new regime tends to work better for people who:
- Have income below ₹12L (tax is zero after rebate)
- Don't have a home loan or significant HRA claim
- Prefer simpler investments not tied to tax-saving lock-in periods
- Are early in their career with fewer deductions
- Want to invest in instruments that don't qualify for 80C (stocks, real estate)
Important: you cannot switch mid-year
Salaried individuals can choose their regime each financial year by informing their employer at the start of the year. However, if you have business income, switching out of the new regime is allowed only once in a lifetime — so choose carefully. Self-employed individuals should consult a CA before deciding.
