Quick answer: The new tax regime — Section 202 of the Income Tax Act, 2025 (Section 115BAC of the 1961 Act) — is the default and has lower slab rates but very few deductions. The old regime usually works out better only when your deductions are large: HRA, home-loan interest, Section 123 (80C), Section 126 (80D) and similar. Compare both on your actual numbers every year.
Every year, the same question comes up around filing season: old regime or new regime? There’s no single right answer, it depends entirely on how many deductions and exemptions you actually claim. Here’s how to actually work it out instead of guessing.
The Core Difference
The old regime has higher tax rates but allows a long list of deductions and exemptions, HRA, 80C investments, home loan interest, and more. The new regime has lower slab rates but strips out almost all of those deductions, in exchange for simplicity.
When the Old Regime Usually Wins
- You’re claiming HRA and actually pay significant rent
- You have a home loan and are claiming interest deduction under Section 24
- You’re maxing out 80C (EPF, PPF, ELSS, life insurance, etc.)
- You have health insurance premiums claimed under 80D
- Your total eligible deductions add up to a meaningful percentage of your income
When the New Regime Usually Wins
- You don’t have major deductions to claim, no home loan, minimal 80C investments
- You’re early in your career with fewer long-term investment commitments
- You’d rather have lower rates and less paperwork than optimise for deductions
Run the Numbers, Don’t Guess
The break-even point depends on your income level and exactly how much you’re claiming in deductions, there’s no flat rule that applies to everyone. Two people earning the same salary can land on opposite answers depending on whether one has a home loan and the other doesn’t.
A Few Things People Get Wrong
- Assuming last year’s choice still makes sense. If your deductions changed, a home loan closed, investments matured, the better regime for you may have changed too.
- Forgetting employers need to know your choice for TDS purposes on salary, separately from what you declare at filing time.
- Not accounting for all deductions when comparing, it’s not just 80C, smaller ones add up.
How the choice is made
- Salaried individuals without business income can choose the old or new regime afresh every year when filing the return.
- Business or professional income: the option to move out of the new regime, and back, is restricted, so the choice needs more care.
- Your employer asks for your regime at the start of the year for salary TDS; you can still choose differently when you file, but expect a difference in tax payable or refund.
Questions to ask before you choose
- Do I pay rent and receive HRA, and how much of it is exempt?
- Do I pay home-loan interest and principal, and is the house self-occupied or let out?
- How much do I actually invest each year in PPF, EPF, ELSS, life insurance or tax-saver deposits — Section 123 of the Income Tax Act, 2025 (Section 80C)?
- Do I pay health insurance premiums for myself or my parents — Section 126 (Section 80D)?
- Will my income or deductions change significantly this year?
If most answers are “no” or the amounts are small, the new regime is usually simpler and cheaper. If the deductions are substantial, calculate the tax both ways before deciding.
