Old vs new regime: how to know which is better for you

Ask five people which tax regime is better and you'll get five confident, contradictory answers — usually based on whatever worked out for their own salary, not a rule that applies generally. There isn't a universal answer, but there is a specific number that settles it for your situation.

The real question isn't "which regime" — it's "how much deduction"

The new regime gives you a larger standard deduction and a higher tax-free threshold, but no HRA exemption and no Section 80C benefit. The old regime is the reverse. Which one wins depends entirely on how much you can legitimately deduct under the old regime — 80C investments, 80D health insurance, HRA, NPS under 80CCD(1B) — combined.

Why the new regime often wins by default

If you're early in your career, don't pay much rent, or haven't started investing under 80C yet, the new regime usually wins simply because you have little to deduct under the old one — its bigger standard deduction is "free" in a way 80C investments are not (you have to actually lock money away to get them).

When the old regime pulls ahead

High rent in a metro city (a large HRA exemption), an existing home loan, or maxed-out 80C and 80D investments can tip the balance back — sometimes decisively. The higher your salary and the more you already claim, the more likely the old regime is worth the extra paperwork.

The actual answer: compute the breakeven

Rather than guessing from general advice, the useful number is: exactly how much more deduction would you need to claim for the old regime to match the new one? If that number is realistic for your salary, the old regime is worth restructuring around. If it's far beyond what you could plausibly invest, stop worrying about it and take the new regime.
