Old or new tax regime? How to choose

A simple way to decide between the old and new income tax regimes in India: list the deductions you can really claim, compare the tax both ways, and know when you can switch.

Key takeaways

  • The new regime has lower rates but allows very few deductions. The old regime has higher rates but lets you claim many.
  • The new regime is the default. If you want the old one, you have to choose it.
  • The right choice depends on how much you can genuinely claim in deductions, not on your salary alone.
  • With salary income you can choose again every year when you file. With business income, switching is far more restricted.

The difference in one minute

India has two ways to calculate income tax, and you pay under one of them each year.

  • The old regime has higher slab rates, but you can reduce your taxable income with deductions and exemptions: section 80C investments (EPF, PPF, ELSS, life insurance, your children's tuition fees, home loan principal), section 80D health insurance, house rent allowance (HRA), home loan interest, leave travel allowance and more.
  • The new regime has lower slab rates, but gives up almost all of those. Salaried people and pensioners still get the standard deduction, and an employer's contribution to your NPS account still counts.

So the question isn't which regime has lower rates — the new one does. It's whether your deductions are big enough to make up for the old regime's higher rates.

Slab rates and limits change in most Budgets, so this guide doesn't quote them. Check the current figures on the Income Tax Department's tax calculator, which compares both regimes for you.

Step 1: List what you can actually claim

Write down only the deductions you would claim anyway, without buying anything new just to save tax:

  • Rent: if you live in a rented home and your salary includes HRA, work out how much of it is exempt.
  • 80C: your EPF contribution (it's on your payslip), PPF, ELSS, life insurance premiums, children's tuition fees and home loan principal. This has an annual limit.
  • Health insurance: premiums for yourself, your family and your parents under 80D.
  • Home loan interest on a house you live in.
  • Anything else your CA or employer has told you that you qualify for, such as education loan interest.

Add these up. If the total is small, you can probably stop here: the new regime will almost certainly cost you less.

Step 2: Compare the tax both ways

Put your income and your deductions into the Income Tax Department's calculator, or ask your CA to run both. The regime with the lower tax wins for this year.

As a rule of thumb, the old regime tends to win only when your deductions are large: typically when you pay rent and claim HRA, repay a home loan, and already use most of your 80C and 80D limits. If you have none or only one of those, the new regime usually comes out ahead.

Look beyond this year, too. If you're only putting money into tax-saving products to stay in the old regime, ask whether you'd choose them anyway. A cheaper tax bill isn't worth an investment that doesn't suit you.

Telling your employer, and switching later

Your employer will ask which regime you want at the start of the year. That choice only decides how much tax (TDS) is deducted from your salary each month.

If your income is from salary, you make the final choice when you file your return, and you can choose differently each year. To use the old regime you must file your return by the due date; a late return is processed under the new regime.

If you have income from a business or profession, the rules are much stricter: choosing the old regime needs a form filed before the due date, and moving back and forth is limited. Talk to a CA before you decide.

When it's worth talking to a CA

For a single salary and a few deductions, the calculator is enough. A chartered accountant is worth it when:

  • you have several income sources — salary plus rent, freelance work, interest or capital gains;
  • you have business or professional income, where the switching rules bite;
  • the two regimes come out close, and the details of your deductions decide it;
  • you're an NRI or have income from abroad.

Questions people ask

Can I claim HRA in the new tax regime?

No. The HRA exemption is one of the benefits you give up in the new regime.

Is the standard deduction available in the new regime?

Yes. Salaried people and pensioners get the standard deduction in both regimes.

Can I change the regime I told my employer?

Yes, if your income is from salary. Your employer's choice only sets the TDS during the year; you make the final choice when you file your return, as long as you file by the due date.

Which regime is better for me?

The one that leaves you paying less tax after the deductions you would genuinely claim. List them, run both regimes through the official calculator, and pick the lower.
