Old vs New Tax Regime: Which Should You Choose?

The new tax regime became the default option a few years ago, and the slab structure has been revised since then too — the “old vs new” comparison many people still reference online uses rates that no longer apply. Here’s the current picture for FY 2026-27, and how to actually decide which regime fits you.

1. The two regimes, in short

India currently runs two parallel personal income tax structures. The old regime has higher slab rates but allows a wide range of deductions and exemptions — HRA, Section 80C investments, home loan interest, and more. The new regime has lower slab rates and a higher basic exemption, but strips out almost all of those deductions. You choose one or the other each year; there’s no blending them.

2. Current tax slabs (FY 2026-27)

These are the new-regime slabs set in Budget 2025 and carried forward unchanged into FY 2026-27. Always confirm current-year rates before filing, since slabs can change with each Union Budget.

The old regime’s slab structure is separate and has not been revised alongside the new regime’s cuts — it retains its own (higher) rates, which is precisely why deductions matter so much more if you stay on it.

3. The rebate that makes income up to ₹12 lakh effectively tax-free

Under Section 87A, taxpayers on the new regime with taxable income up to ₹12,00,000 get a rebate of up to ₹60,000, which fully cancels out the tax otherwise payable on that income. In practice, this means most salaried taxpayers earning up to ₹12 lakh a year pay zero income tax under the new regime, even though the slab table above shows non-zero rates kicking in from ₹4 lakh — the rebate absorbs that liability entirely up to the threshold. Above ₹12 lakh, tax is calculated normally on the full slab structure with no rebate cushion.

4. What deductions the old regime allows (that the new regime doesn’t)

The old regime’s main advantage comes from a set of deductions the new regime largely removes:

• Section 80C — up to ₹1,50,000 for PPF, ELSS, life insurance premiums, and similar instruments
• HRA exemption — for salaried employees paying rent
• Home loan interest — up to ₹2,00,000 under Section 24(b) for a self-occupied property
• Standard deduction — available on both regimes, but historically was old-regime-only before recent reforms extended it
• Section 80D — health insurance premiums

If your deductions comfortably exceed the gap between what the two regimes would otherwise charge you, the old regime usually wins. If you don’t have many of these deductions to claim, the new regime’s lower rates (plus the rebate up to ₹12 lakh) usually come out ahead.

5. Worked example

Someone earning ₹15,00,000 a year, claiming ₹3,00,000 in total deductions (80C, home loan interest, and standard deduction) under the old regime:

The gap depends heavily on the exact deduction total and current slab rates in force for the year you’re filing — always run your own numbers with the Income Tax Calculator rather than relying on illustrative figures, since both regimes’ rates are subject to change with each Budget.

6. Who tends to benefit from each regime

Salaried employees with a home loan, significant 80C investments, and HRA claims often still come out ahead on the old regime, especially at higher income levels where the deduction value outweighs the lower new-regime rates. Younger earners, those without a home loan, freelancers with fewer eligible deductions, and anyone under the ₹12 lakh rebate threshold typically do better on the new regime — simpler filing, no need to hunt for eligible investments, and often a lower net tax bill regardless.

7. Can you switch between regimes each year?

Salaried individuals without business income can switch between the old and new regime every financial year when filing — there’s no lock-in. Those with business or professional income have a more restricted ability to switch back and forth once they’ve opted out of the new regime, so the choice carries more weight for that group. If your deduction-eligible expenses (home loan, investments, insurance) change meaningfully year to year, it’s worth re-running the comparison annually rather than assuming last year’s choice still holds.

8. Surcharge and cess: the part most comparisons skip

The slab table only covers the base income tax rate — actual tax liability also includes a health and education cess of 4% on the total tax computed, plus a surcharge for very high earners (income above ₹50 lakh, with the surcharge rate rising in steps at higher thresholds). Both regimes apply cess the same way, but the surcharge treatment differs slightly between them at the top end, which matters mainly for high-income taxpayers rather than the typical salaried filer. For most people comparing the two regimes at moderate income levels, the cess is the only add-on that meaningfully affects the final number, and it applies proportionally regardless of which regime you pick.

9. How the new regime’s rate cuts evolved

The new regime was introduced with a wider set of narrower slabs and minimal exemptions, positioned as a simpler, lower-friction filing option for people without large deduction claims. Successive Budgets have both widened the nil-tax bracket and reshaped the slab boundaries — the current 7-bracket structure with a ₹4 lakh exemption and 25% intermediate bracket reflects the latest revision, replacing an earlier structure that had fewer brackets and a lower exemption threshold. This is exactly why online comparisons written even a year or two ago can describe a materially different regime than the one currently in force — always check the filing-year-specific slabs rather than trusting a general explainer’s numbers at face value.

10. Standard deduction on both regimes

Both the old and new regimes now allow a standard deduction for salaried taxpayers and pensioners, reducing taxable salary income by a fixed amount before slab rates are applied. This was historically an old-regime-only benefit, but recent reforms extended a version of it to the new regime as well, narrowing one of the gaps between the two options. The exact deduction amount can differ between the two regimes, so it’s worth checking the current figure for each rather than assuming they match.

11. Capital gains and other income types

The regime choice affects tax on salary and other regular income, but capital gains (from selling stocks, mutual funds, or property) are taxed under their own separate rules regardless of which regime you’ve chosen for your regular income — short-term and long-term capital gains have their own rates and holding-period definitions, largely unaffected by the old-vs-new regime decision. If a meaningful share of your income comes from capital gains rather than salary, the regime choice matters less overall, since that portion of your tax bill is calculated independently either way.

12. A simple way to decide

Rather than guessing, add up every deduction you’d genuinely claim under the old regime — 80C investments you already make, actual HRA paid, real home loan interest, health insurance premiums — and compare the resulting old-regime tax against the new-regime tax on your full income with no deductions. If the old-regime figure (after deductions) is lower, stay old; if the new-regime figure is lower, switch. The mistake most people make is estimating deductions optimistically rather than using what they’d actually claim — a home loan you’re planning to take next year doesn’t count for this year’s comparison.

This table is a starting heuristic, not a substitute for actually calculating both scenarios with your real numbers — the exact crossover point shifts with every Budget’s slab changes, so what was true last year isn’t guaranteed to hold this year.

13. Common mistakes when comparing regimes

The most common mistake is comparing the two regimes using stale slab rates — both regimes’ structures have shifted over recent Budgets, and an outdated comparison can flip the “better” answer entirely. The second is forgetting the Section 87A rebate when estimating new-regime tax, which makes the new regime look worse than it actually is for income up to ₹12 lakh. The third is only counting 80C investments and forgetting HRA, home loan interest, or health insurance premiums, which can materially change which regime actually wins for a given income and deduction profile.
