New Regime vs Old Regime: Which Saves You More Tax? (FY 2025-26)
Every salaried person in India now faces the same yearly question: New Tax Regime or Old? The New Regime is the default and has lower slab rates. The Old Regime has higher rates but lets you claim deductions. There's no single right answer — it genuinely depends on your numbers. This guide shows you exactly how to figure out which one keeps more money in your bank.
The core trade-off in one line
The New Regime gives you lower tax rates but almost no deductions. The Old Regime gives you higher tax rates but lots of deductions. So the whole decision comes down to a single question: are your deductions big enough to outweigh the New Regime's lower rates and generous rebate? If yes, Old wins. If not, New wins.
New Regime — the FY 2025-26 numbers
Under the New Regime for FY 2025-26, income up to ₹4 lakh is tax-free, then the slabs rise: 5% (₹4–8L), 10% (₹8–12L), 15% (₹12–16L), 20% (₹16–20L), 25% (₹20–24L), and 30% above ₹24 lakh. You also get a ₹75,000 standard deduction.
The headline feature is the Section 87A rebate: if your taxable income is up to ₹12 lakh, your tax is fully rebated to zero. Combined with the standard deduction, this means a salary of roughly ₹12.75 lakh can end up paying no income tax at all. Just above ₹12 lakh, marginal relief ensures your extra tax never exceeds the income earned over the threshold — so there's no cliff.
The catch: the New Regime disallows almost all deductions — no 80C, no 80D, no HRA. What you see in the slabs is essentially what you pay.
Old Regime — the FY 2025-26 numbers
The Old Regime slabs are unchanged: nil up to ₹2.5 lakh, then 5% (₹2.5–5L), 20% (₹5–10L), and 30% above ₹10 lakh. The standard deduction is ₹50,000, and the 87A rebate makes taxable income up to ₹5 lakh tax-free (a smaller rebate of ₹12,500).
The Old Regime's real value is what it lets you subtract before the slabs even apply:
- 80C — up to ₹1.5 lakh for PPF, ELSS, EPF, life insurance, and more.
- 80CCD(1B) — an extra ₹50,000 for NPS, on top of 80C.
- 80D — health insurance premiums.
- HRA — house rent allowance exemption, often substantial for renters.
- Home loan interest — up to ₹2 lakh under Section 24(b).
Add these up and a person with a home loan, full 80C, NPS, health insurance, and HRA can shield several lakhs from tax — which can beat the New Regime despite the higher rates.
So which one wins for you?
Here's the honest rule of thumb: the Old Regime only wins when your total deductions are large. If you claim few or no deductions — which is true for many younger salaried people who rent informally, haven't taken a home loan, and don't max out 80C — the New Regime almost always wins, thanks to its lower rates and the ₹12 lakh rebate.
Roughly speaking, the more you genuinely invest in tax-saving instruments and the bigger your HRA and home loan interest, the more the Old Regime tilts in your favour. If those are small, don't force it — the New Regime's simplicity and lower rates will likely serve you better.
Don't guess — the only reliable way to know is to run your exact salary through both regimes. Our In-Hand Salary Calculator lets you switch between New and Old with one tap and see your real take-home under each, on the actual FY 2025-26 rules.
One important note
The New Regime is now the default — if you do nothing, that's what applies. To use the Old Regime, salaried taxpayers can simply select it while filing their return each year. So you're free to compare and choose whichever leaves you better off, every single year.
