Every year around tax-filing season, the same question comes up: old regime or new regime? The honest answer is "it depends on your specific deductions," which isn't very satisfying — but the framework for figuring it out for yourself is simpler than it looks.
Why you can't just compare slab rates
The new tax regime generally offers lower slab rates but strips out most deductions and exemptions (like HRA, most Section 80C investments, and home loan interest on a self-occupied property). The old regime has higher slab rates but lets you reduce your taxable income substantially if you actually use the available deductions. Comparing the headline rates alone tells you nothing — what matters is your taxable income after deductions under the old regime, compared against your income taxed at the new regime's lower rates with minimal deductions.
The deductions that usually tip the balance
If you genuinely use most of these, the old regime often works out better; if you use few or none, the new regime usually wins:
- Section 80C — EPF, PPF, ELSS, life insurance premiums, principal repayment on a home loan, children's tuition fees (up to the annual limit).
- HRA — if you pay rent and receive HRA as part of your salary, this can be a substantial deduction, especially in a metro city.
- Home loan interest — deduction on interest paid for a self-occupied property, under Section 24.
- Section 80D — health insurance premiums for yourself and your family.
- NPS employer contribution and a few other targeted deductions, some of which remain available even under the new regime — worth checking which ones still apply.
A practical way to actually check
Add up your genuine, actually-used deductions for the year (not hypothetical ones) — rent paid with HRA claimed, actual 80C investments, real health insurance premiums, home loan interest if applicable. If that total is large relative to your income, the old regime is more likely to come out ahead. If it's small — for instance, if you don't pay rent, haven't invested toward 80C, and don't have a home loan — the new regime's lower slabs will usually win with far less paperwork.
It's not a permanent choice
Salaried individuals can generally choose between the two regimes each financial year when filing their return (rules differ slightly for those with business income, who face more restrictions on switching back and forth). This means your decision isn't locked in forever — if your deduction profile changes (you take a home loan, start renting, or ramp up 80C investments), it's worth re-running the comparison the following year rather than assuming last year's answer still holds.
When in doubt
Most salary and tax-filing platforms let you preview your tax liability under both regimes before you file — actually run both numbers rather than guessing. Given how often slab rates and deduction rules are revised in the Union Budget, treat this as a number worth re-checking every year, not a one-time decision.
