Every salaried Indian asks the same question in March — should I pick the Old Regime or the New Regime? Since Budget 2025 made the New Regime the default and pushed the 87A rebate up to ₹12 lakh taxable income, the answer has changed for most people. But "most" isn't "all".
This guide walks you through the FY 2025-26 (AY 2026-27) slabs, three real salary examples, and a clear rule of thumb so you stop guessing — and start with the right regime when you file.
Quick Answer (TL;DR)
| Your situation | Likely better |
|---|---|
| Salary ≤ ₹12L, no big deductions | New Regime (often zero tax) |
| Salary ₹12L–₹20L, weak deductions (<₹2.5L) | New Regime |
| Salary ₹12L–₹20L, strong deductions (₹3L+) | Old Regime |
| Salary ₹20L+, home loan interest + 80C + NPS maxed | Old Regime |
| You hate paperwork | New Regime |

FY 2025-26 New Regime Slabs (The Default)
Budget 2025 rewrote the New Regime slabs. They now look like this:
| Taxable Income | Tax Rate |
|---|---|
| Up to ₹4,00,000 | 0% |
| ₹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% |
The 87A rebate is the headline change. If your taxable income (after the ₹75,000 standard deduction) is ₹12,00,000 or less, your tax bill is ₹0 — the government rebates the full slab tax. A salaried person earning up to ₹12.75L gross pays nothing under the New Regime.
What you lose under the New Regime:
- 80C (PPF, ELSS, life insurance, EPF)
- 80CCD(1B) (₹50K extra NPS)
- 80D (health insurance)
- 24(b) (home loan interest)
- HRA exemption
- LTA
What you keep:
- ₹75,000 standard deduction (salaried)
- 80CCD(2) — your employer's NPS contribution (still deductible)
Old Regime Slabs (Unchanged for Years)
| Taxable Income | 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% |
Standard deduction is ₹50,000 (not ₹75K). 87A rebate caps at ₹12,500, and only kicks in if taxable income ≤ ₹5L.
The Old Regime's superpower: every legal deduction you can claim. 80C, NPS, home loan, HRA, 80D, 80E — they all reduce taxable income. The more you claim, the more sense it makes.
Side-by-Side: 3 Real Salary Examples
All numbers assume salaried, FY 2025-26, and a fairly typical Indian metro deduction profile.
Example 1 — ₹10 LPA, light deductions
- 80C: ₹50,000 · 80D: ₹15,000 · HRA: ₹0
| Old Regime | New Regime | |
|---|---|---|
| Taxable income | ₹8,85,000 | ₹9,25,000 |
| Tax + cess | ~₹91,000 | ₹0 (87A rebate) |
Winner: New Regime by ~₹91,000.
Example 2 — ₹18 LPA, moderate deductions
- 80C: ₹1,50,000 · 80CCD(1B): ₹50,000 · 80D: ₹25,000 · HRA: ₹1,80,000
| Old Regime | New Regime | |
|---|---|---|
| Taxable income | ₹12,45,000 | ₹17,25,000 |
| Tax + cess | ~₹1,98,000 | ~₹1,87,000 |
Winner: New Regime by ~₹11,000 — barely. If you add ₹50K more to 80C or have ₹1L of home loan interest, Old flips ahead.
Example 3 — ₹30 LPA, max deductions + home loan
- 80C: ₹1,50,000 · 80CCD(1B): ₹50,000 · 80D: ₹50,000 · HRA: ₹3,00,000 · Home loan interest 24(b): ₹2,00,000
| Old Regime | New Regime | |
|---|---|---|
| Taxable income | ₹21,00,000 | ₹29,25,000 |
| Tax + cess | ~₹4,52,000 | ~₹5,52,000 |
Winner: Old Regime by ~₹1,00,000.
The 3-Line Rule of Thumb
Add up all the deductions you actually claim (not what's theoretically possible):
80C + 80CCD(1B) + 80D + 24(b) home loan interest + HRA exemption
- Under ₹2,00,000? New Regime almost always wins.
- ₹2,00,000 – ₹4,00,000? It's a coin flip — calculate both.
- Over ₹4,00,000? Old Regime usually wins, especially above ₹15L gross.
The threshold goes up as your salary goes up, because the New Regime's slabs are kinder at higher incomes.
Common Mistakes People Make
1. Picking the regime once and forgetting it. Salaried employees can switch every year. Your deductions change (rent, home loan, new health policy) — re-evaluate every March.
2. Claiming 80C just to "save tax" under New Regime. Under the New Regime, your ELSS or PPF doesn't reduce tax at all. They're still good investments — but pick them for returns and liquidity, not for a tax break you won't get.
3. Forgetting employer NPS (80CCD(2)). This deduction works under both regimes — up to 14% of basic for govt employees, 10% for private. Ask HR to enable it; it's free tax savings.
4. Skipping HRA when renting. If you rent and your Old-Regime HRA exemption alone is ₹2L+, Old Regime probably wins outright. Many people forget to even compute HRA.
5. Surcharge surprise. Above ₹50L taxable income, surcharge kicks in (10% → 37%). The Old Regime caps surcharge at 25% under the new rules. Big earners — calculate carefully.
Save Tax, Then Actually Invest It
Picking the right regime is only half the win. The bigger one is investing the tax you saved, not spending it.
If the New Regime saves you ₹80,000 this year and you SIP it monthly at ~12%, that's ~₹6,700/month — which compounds into serious money. Our guide on how much you need to invest every month to reach ₹1 Crore shows exactly what monthly SIPs at different time horizons look like.

FAQs
Is the New Tax Regime really better in 2025?
For most salaried Indians earning up to ~₹15 LPA without major deductions, yes — the ₹12L rebate and ₹75K standard deduction make it hard to beat. But if you have a home loan, big 80C investments, and claim HRA, the Old Regime can still save more. Always compare both.
What is the 87A rebate of ₹12 lakh?
Under the New Regime for FY 2025-26, if your taxable income (gross minus standard deduction) is ₹12,00,000 or less, the government rebates 100% of your slab tax. Net tax payable: ₹0. For salaried, that means up to ₹12.75L gross can be tax-free.
Can I switch between Old and New Regime every year?
If you have only salary income, yes — you can switch every financial year by indicating your choice while filing your ITR. If you have business or professional income, the switch is one-time only.
What is the standard deduction for FY 2025-26?
₹50,000 under the Old Regime, ₹75,000 under the New Regime. Both apply only to salaried and pension income.
Does 80C work under the New Regime?
No. 80C, 80CCD(1B), 80D, HRA, home loan interest, and most other deductions are NOT available under the New Regime. Only 80CCD(2) (employer NPS) and the standard deduction survive.
How much deductions do I need for the Old Regime to be better?
Rough rule: total deductions (80C + 80CCD(1B) + 80D + 24(b) + HRA) above ₹3.5–₹4 lakh usually tip the scales toward the Old Regime, especially for salaries above ₹15 LPA.
Is HRA available in the New Regime?
No. HRA exemption is an Old Regime deduction only. If you pay significant rent, calculate your HRA exemption and check whether it pushes you into Old Regime territory.
How do I calculate my tax under both regimes?
Use the free FundGenie Tax Calculator. Enter your CTC, choose your basic and HRA split, fill in your deductions, and it shows both regimes side-by-side with a recommendation — all in under a minute, no login needed.
