Old vs New Tax Regime: Which Saves You More?
The break-even is roughly Rs 3.75-4 lakh of deductions. Here's how to know which side you're on.
Choose the old regime if your total deductions exceed roughly Rs 3.75–4 lakh — typically anyone with a home loan, full 80C and HRA. Choose the new regime if you claim little or nothing, since its lower slab rates then win outright. The new regime is the default: if you don't actively opt for the old one when filing, you're placed in the new one automatically.

|---|---|---|
| Standard deduction (salaried) | Yes | Yes |
| 80C (PPF, ELSS, EPF, insurance) up to Rs 1.5L | Yes | No |
| HRA exemption | Yes | No |
| Home loan interest (Sec 24) up to Rs 2L | Yes | No (self-occupied) |
| 80D health insurance | Yes | No |
| NPS 80CCD(1B) extra Rs 50,000 | Yes | No |
| LTA | Yes | No |
| Employer NPS 80CCD(2) | Yes | Yes |
The one calculation that decides it
Forget the slab tables for a moment. Add up what you actually claim — not what you could theoretically claim:
- 80C: PPF + EPF + ELSS + life insurance + kids' tuition, capped at Rs 1.5 lakh
- HRA exemption (see the three-rule test)
- Home loan interest, capped at Rs 2 lakh
- 80D health insurance premiums
- NPS under 80CCD(1B), capped at Rs 50,000
If that total clears roughly Rs 3.75–4 lakh, the old regime almost certainly costs you less. Below it, the new regime does. The exact break-even shifts with income level, which is why you should run both rather than trust the rule of thumb.
Who lands where, in practice
New regime usually wins: young earners living with family (no rent, so no HRA), people early in their careers with no home loan, anyone who finds tax-saving investments a nuisance, and those who'd rather hold liquid money than lock it in 80C products.
Old regime usually wins: anyone paying a home loan EMI, salaried renters in metros with a decent HRA component, people already maxing 80C through EPF alone, and those paying health premiums for parents.
One nuance worth knowing: the old regime effectively subsidises your PPF and insurance contributions. If you'd invest that money anyway, the deduction is free money. If you're only investing to claim the deduction, you're locking up capital for a partial tax break — often a bad trade.
Can you switch regimes later?
Salaried employees can switch every year at filing, regardless of what you told your employer for TDS. Telling HR “new regime” in April doesn't bind you in July — you can still file under the old one and claim a refund, or vice versa.
Business and professional income is different: you can move from old to new freely, but once you switch back to old, you generally get only one more opportunity to opt into the new regime in your lifetime. Get advice before switching if you have business income.

Frequently asked questions
Which regime is better, old or new?
Add up the deductions you actually claim. Above roughly Rs 3.75–4 lakh total, the old regime usually saves more; below that, the new regime's lower rates win. Anyone with a home loan, full 80C and HRA is nearly always better off in the old regime; someone with no rent and no investments is better off in the new one. Run both in an income tax calculator with your real figures.
Can I switch between the old and new tax regime every year?
Salaried taxpayers can choose afresh each financial year when filing, and it doesn't have to match what you declared to your employer for TDS. Taxpayers with business or professional income have far less flexibility: moving back to the old regime generally leaves only one further chance to opt into the new one.
Is HRA allowed in the new tax regime?
No. HRA exemption is only available under the old regime, and it's typically the single largest deduction a salaried renter has. If you're paying substantial metro rent with a decent HRA component in your salary, that alone can be enough to make the old regime cheaper. Use an HRA calculator to size it before deciding.
Which regime applies if I don't choose?
The new regime is the default. If you don't explicitly opt for the old regime while filing your return, you'll be assessed under the new one and lose HRA, 80C, 80D and home loan interest deductions for that year. If the old regime is better for you, you must actively select it — it is not applied automatically.
