Since the new tax regime became the default option in FY 2023-24, one question keeps coming up every single year at tax-planning time: should you stick with the old regime and claim your deductions, or switch to the new regime and its lower slab rates? For FY 2026-27, Budget 2026 left both sets of slab rates unchanged from FY 2025-26 — so the comparison that mattered last year still matters now. Here’s how the two regimes actually stack up, and how to figure out which one puts more money in your pocket.
New tax regime slabs for FY 2026-27
The new regime uses wider, lower-rate slabs and (mostly) skips deductions in exchange:
- ₹0 – ₹4,00,000: Nil
- ₹4,00,000 – ₹8,00,000: 5%
- ₹8,00,000 – ₹12,00,000: 10%
- ₹12,00,000 – ₹16,00,000: 15%
- ₹16,00,000 – ₹20,00,000: 20%
- ₹20,00,000 – ₹24,00,000: 25%
- Above ₹24,00,000: 30%
Two things make this regime more generous than the slabs alone suggest. First, salaried taxpayers still get a standard deduction of ₹75,000. Second, the Section 87A rebate for FY 2026-27 is ₹60,000, which wipes out tax entirely on taxable income up to ₹12,00,000. Put together, a salaried individual with gross income up to roughly ₹12,75,000 can end up paying zero tax under the new regime, before even claiming any other deduction.
Old tax regime slabs for FY 2026-27
The old regime keeps its narrower slabs but allows the full menu of deductions:
- ₹0 – ₹2,50,000: Nil
- ₹2,50,000 – ₹5,00,000: 5%
- ₹5,00,000 – ₹10,00,000: 20%
- Above ₹10,00,000: 30%
The old regime’s real strength isn’t the slabs — it’s everything you can subtract before you get to a taxable number: a ₹50,000 standard deduction, up to ₹1,50,000 under Section 80C (PPF, ELSS, EPF, life insurance, tuition fees), Section 80D for health insurance premiums, HRA exemption if you pay rent, and home loan interest deduction under Section 24(b), among others. Stack enough of these and your effective tax rate can drop well below what the new regime offers on the same gross income. The old regime also has a Section 87A rebate, but it only zeroes out tax up to ₹5,00,000 of taxable income — far lower than the new regime’s ₹12,00,000 threshold.
So which one actually saves you more?
It comes down to one number: how much you can genuinely claim in deductions under the old regime. As a rough rule of thumb:
- Little to no deductions claimed (no rent, minimal 80C, no home loan) — the new regime almost always wins, sometimes by a wide margin, because of the higher rebate threshold and standard deduction.
- Moderate deductions (full 80C + basic health insurance, no HRA) — it’s close, and depends heavily on your income level. Middle-income earners around ₹10–15 lakh often find the two regimes land within a few thousand rupees of each other.
- Heavy deductions (HRA + full 80C + home loan interest + health insurance) — the old regime frequently still wins for salaried employees paying rent in a metro city or servicing a large home loan, especially at higher income levels where the 30% slab kicks in earlier under the old regime but the deductions shrink the taxable base more.
There’s no universal answer because it depends entirely on your specific deduction total, not just your salary. That’s exactly the kind of calculation that’s tedious to do by hand and easy to get wrong — a small error in one section can flip which regime looks cheaper.
Run your own numbers
Rather than estimate, plug your actual income and deduction figures into the Old vs New Tax Regime Comparator. It calculates your tax liability under both regimes side by side using the current FY 2026-27 slabs and rebate rules, so you can see the exact rupee difference instead of relying on a rule of thumb.
A few calculators that feed directly into this decision:
- HRA Exemption Calculator — work out your exact tax-free HRA amount, the single biggest swing factor for salaried renters deciding between regimes.
- EPF Calculator — project your EPF balance, useful when totaling up your 80C contributions.
- Net Salary (In-Hand) Calculator — see your actual take-home pay after tax, once you know which regime you’re using.
Frequently asked questions
Can I switch between regimes every year?
Salaried individuals without business income can choose either regime each financial year when filing their return. Those with business or professional income have more restrictions on switching back and forth, so it’s worth checking the current rules before assuming you can flip annually.
Is the new regime automatically applied if I don’t choose?
Yes — the new regime is the default. If you want the old regime, you (or your employer, for TDS purposes) need to actively opt in.
Does the old regime still make sense if I have a home loan?
Often, yes. Home loan interest under Section 24(b), combined with 80C principal repayment and HRA if applicable, is usually enough to tip the balance toward the old regime for many borrowers — but the only way to know for sure is to run the actual numbers for your income and interest amount.
What if my income changes mid-year?
Re-run the comparison whenever your income, rent, or investment amounts change meaningfully — a regime that made sense at ₹10 lakh income may not be the better choice at ₹18 lakh.
Neither regime is universally “better” — it’s a function of your specific numbers, not a general rule. Five minutes with the comparator calculator will tell you more than any blanket recommendation.
