Old vs New Tax Regime FY 2025-26: The ₹8 Lakh Rule Before You File
ITR filing for FY 2025-26 is open and the clock to 31 July 2026 is ticking. If you earn ₹15L or more, the single choice that moves your tax bill the most isn't which ELSS you bought in March — it's which regime you tick on the return. Pick wrong and you hand over ₹50,000 to ₹1,00,000 for a year you can't redo. Here is the exact rupee line that settles it.
Summary
The new regime gives a ₹75,000 standard deduction and gentler slabs but switches off almost every other deduction. The old regime keeps 80C, 80D, HRA and home-loan interest alive but taxes at 30% past ₹10L. The old regime only pulls ahead once your other deductions — everything beyond the standard deduction — cross this line:
| Gross salary | New-regime tax (FY 2025-26) | Old regime wins only if your deductions exceed |
|---|---|---|
| ₹15,00,000 | ₹97,500 | ₹5,43,750 |
| ₹20,00,000 | ₹1,92,400 | ₹7,08,000 |
| ₹25,00,000 | ₹3,19,800 | ₹8,00,000 |
| ₹30,00,000 | ₹4,75,800 | ₹8,00,000 |
Tax figures include 4% cess. "Deductions" here means 80C + 80CCD(1B) NPS + 80D + HRA under Section 10(13A) + home-loan interest under Section 24 — over and above the standard deduction. Read the last column as a hurdle: above ₹24L of taxable income it flattens at roughly ₹8 lakh. Clear it and the old regime is cheaper; miss it and the new regime wins. (Above ₹50L the gap widens further in the new regime's favour — its surcharge is capped at 25% versus 37% in the old regime.)
How the two regimes actually differ in FY 2025-26
The new regime slabs are the real draw
Post-Budget 2025, the new-regime slabs run 0% to ₹4L, 5% to ₹8L, 10% to ₹12L, 15% to ₹16L, 20% to ₹20L, 25% to ₹24L, and 30% above. With the ₹75,000 standard deduction and the Section 87A rebate of ₹60,000, income up to ₹12.75L is fully tax-free. The catch: no 80C, no 80D, no HRA, no home-loan interest on a self-occupied house.
The old regime only earns its keep with real deductions
The old slabs are unchanged — 5% from ₹2.5L, 20% from ₹5L, 30% above ₹10L — with a smaller ₹50,000 standard deduction and an 87A rebate that dies at ₹5L income. It is worth choosing only if you are genuinely stacking deductions: ₹1.5L under 80C, ₹50,000 under 80CCD(1B), ₹25,000–₹75,000 under 80D, HRA, and ideally ₹2L of home-loan interest under Section 24.
Why the hurdle is ~₹8 lakh, not a vibe
Once your taxable income is past ₹24L, every extra rupee is taxed at 30% in both regimes, so the gap between them stops moving. That gap — the new regime's built-in slab advantage — works out to roughly ₹8 lakh of deductions. Below ₹24L the hurdle is lower (₹5.4L at ₹15L income) because your top slab is still 15–20%. This is why a blanket "old regime is better if you have a home loan" is wrong: a ₹2L home-loan interest claim plus ₹2L of 80C/NPS/80D rarely clears ₹8L on its own.
Two traps that quietly cost salaried filers the old regime
This is where most ₹15L+ earners lose money without realising it.
The new regime is now the default
Under Section 115BAC, if you do nothing, you are taxed under the new regime. To use the old regime you must actively select it in the return. Salaried filers without business income can do this directly in the ITR every year — but only if they make the choice deliberately.
A belated return locks you into the new regime
Choosing the old regime is allowed only when you file by the 31 July 2026 due date under Section 139(1). Miss it, file a belated return, and you forfeit the old regime for FY 2025-26 entirely — even if your deductions would have saved you a lakh. If you have business or professional income, the rules are stricter still: you must file Form 10-IEA to opt out of the new regime, and you only get one switch back.
The new ITR-1 rules: many of you can skip ITR-2 this year
A genuinely new change for AY 2026-27 that the deadline coverage glosses over. ITR-1 (Sahaj) now accepts:
- Two house properties instead of one — a self-occupied home plus a second vacant or let-out flat no longer forces you into ITR-2.
- Long-term capital gains up to ₹1.25L under Section 112A — small equity and mutual-fund gains within the exemption limit can be reported on the simpler form.
So if last year you were pushed to ITR-2 only because of a second property or a modest LTCG, check ITR-1 first this year. Forms also now allow a secondary mobile number and email and both primary and secondary addresses. ITR-1 still won't work if you have capital losses to carry forward, foreign assets, or income above ₹50L — those stay on ITR-2.
Real example: Salaried, ₹28L CTC, Bengaluru
Priya earns ₹28L, rents in Bengaluru, and stacks her deductions: ₹1.5L (80C), ₹50,000 (80CCD(1B) NPS), ₹25,000 (80D), and ₹3L of HRA exemption — ₹5.25L beyond the standard deduction. Solid, but short of the ₹8L hurdle for her income.
| Item | Old regime | New regime |
|---|---|---|
| Taxable income | ₹22,25,000 | ₹27,25,000 |
| Annual tax (incl. 4% cess) | ₹4,99,200 | ₹4,13,400 |
| Monthly take-home (post-tax) | ₹1,91,700 | ₹1,98,900 |
| Verdict | — | ✅ saves ₹85,800/yr |
Even with ₹5.25L of deductions, Priya is ₹85,800 a year better off in the new regime. To flip the result she would need a large home loan pushing her deductions past ₹8L — which she doesn't have. For her, the simpler new regime is also the cheaper one.
What to do this week
- Pull your Form 16, AIS and Annual Information Statement, and total your actual deductions — 80C, 80CCD(1B), 80D, HRA, home-loan interest — not the ones you meant to claim.
- Run both regimes on those real numbers. Compare against your income band's hurdle in the table above before you assume the old regime is better.
- If you're choosing the old regime, file on or before 31 July 2026 — a belated return locks you out of it.
- Check whether your case now fits ITR-1 (two properties, LTCG up to ₹1.25L) before defaulting to ITR-2.
The bottom line
The regime decision isn't ideology, it's arithmetic: above ₹24L taxable, the old regime is worth it only if your deductions beat roughly ₹8 lakh, and the threshold is lower below that. Most ₹15L+ salaried earners without a big home loan are better off in the new regime — but the only way to be sure is to run your own numbers before you file, because you're locked in for the year once you do.
