The new tax regime offers lower slab rates but strips out most deductions and exemptions — HRA, Section 80C, 80D, home loan interest under Section 24, and more. The old regime keeps all of these but taxes you at higher slab rates on your net income after deductions. There's no universally right answer; it depends entirely on how much you actually claim, and the gap between the two regimes has shifted meaningfully with recent slab revisions, so a decision you made a couple of years ago is worth revisiting rather than assuming it still holds.
The Current New Regime Slabs
As of the current structure, the new regime (which remains the default regime unless you actively opt for the old one) taxes income as follows:
- Up to ₹4 lakh — Nil
- ₹4 lakh to ₹8 lakh — 5%
- ₹8 lakh to ₹12 lakh — 10%
- ₹12 lakh to ₹16 lakh — 15%
- ₹16 lakh to ₹20 lakh — 20%
- ₹20 lakh to ₹24 lakh — 25%
- Above ₹24 lakh — 30%
On top of this slab structure, an enhanced rebate under Section 87A means income up to ₹12.75 lakh effectively attracts zero tax under the new regime for salaried taxpayers (accounting for the standard deduction) — a materially higher zero-tax threshold than the old regime offers at any comparable deduction level. Above ₹12.75 lakh, tax is computed slab-by-slab from ₹4 lakh onward, not just on the excess over the rebate threshold.
When the Old Regime Still Usually Wins
If you have a home loan (interest deduction up to ₹2 lakh under Section 24 for a self-occupied property), contribute meaningfully to 80C-eligible instruments (PPF, ELSS, life insurance premiums, up to ₹1.5 lakh combined), pay health insurance premiums (up to ₹25,000-₹50,000 depending on age under Section 80D), and claim HRA as a salaried employee living in a rented home, your total deductions can easily cross ₹4-5 lakh. At that level, the old regime's higher slabs applied to a much smaller taxable base often still comes out cheaper than the new regime's lower slabs applied to your full income — but this now requires genuinely substantial deductions given how much the new regime's zero-tax threshold has risen.
When the New Regime Usually Wins
If you don't have a home loan, don't invest heavily in 80C-eligible instruments, and don't pay significant rent qualifying for HRA, you're likely claiming well under ₹2 lakh in total deductions — and given the new regime's ₹12.75 lakh effective zero-tax point, a large share of salaried taxpayers without major deductions now come out ahead, or at worst roughly even, under the new regime. It's also simply simpler to file, with fewer proofs to gather and retain.
A Worked Example
Consider a salaried individual earning ₹15 lakh gross, with a home loan (₹2 lakh interest deduction), ₹1.5 lakh in 80C investments, and ₹25,000 in health insurance premium — roughly ₹3.75 lakh in deductions plus the standard deduction. Under the old regime, taxable income drops to roughly ₹11 lakh after deductions, taxed at old-regime slab rates. Under the new regime, the full ₹15 lakh (less standard deduction) is taxed at the slabs above, with no benefit from the home loan or 80C investments at all. Whether old or new wins here depends on the precise old-regime slab structure in force and needs an actual calculation with current numbers — which is exactly why a rate-table comparison alone isn't enough; you need your specific figures run both ways.
The Practical Way to Decide
Don't compare headline rate tables in isolation — compute your actual tax liability both ways using your real income and real deduction figures, ideally using the exact numbers you'd use for filing. Most tax calculators (including the government's own portal calculator) let you toggle between regimes with your actual salary structure and deductions entered, giving a direct rupee comparison rather than an abstract rate comparison.
Salaried employees can switch regimes every single financial year when filing — there's no lock-in, so this is a decision worth revisiting annually, not a one-time choice. Those with business or professional income face more restricted switching rules (broadly, one switch back to the old regime is allowed, after which the choice is more constrained), so the decision carries more permanent weight for that group and deserves more careful upfront analysis.
If your deductions genuinely change year to year — you took a new home loan this year, or a 5-year tax-saver instrument matured and you haven't reinvested — it's worth re-running this comparison every filing season rather than defaulting to whatever you chose last time out of habit.
Frequently Asked Questions
Can I claim the standard deduction under the new regime? Yes — the standard deduction for salaried individuals and pensioners is available under both regimes, and it's factored into the ₹12.75 lakh effective zero-tax threshold mentioned above.
If I have business income, can I switch regimes every year like a salaried person? No — taxpayers with business or professional income have a more restricted switching option, generally limited to one opportunity to switch back to the old regime after opting for the new one, after which further switching is constrained. This makes the initial choice more consequential for business owners than for salaried employees.
Does choosing the new regime affect my eligibility for other tax benefits, like Section 54 capital gains exemptions? No — capital gains exemptions under sections like 54, 54F, and similar provisions operate independently of which regime you choose for your regular income tax computation; the regime choice primarily affects slab rates and Chapter VI-A deductions (80C, 80D, etc.), not capital gains exemption provisions.
