Individual taxpayers in India can choose between two income tax regimes. The new regime offers lower slab rates but allows very few deductions and exemptions. The old regime has higher rates but lets you reduce taxable income through deductions such as investments, insurance premiums, home loan interest and HRA.

The new regime is now the default — if you want the old regime, you need to opt for it.

The core trade-off

Think of it this way:

  • New regime: lower rates, simpler filing, few deductions.
  • Old regime: higher rates, but you can claim a long list of deductions.

So the old regime only works out better if your total deductions are large enough to outweigh the benefit of the new regime's lower rates.

The "better" regime isn't the same for everyone — or even for you every year. It depends on your income and the deductions you actually claim.

A four-step comparison

  1. List the deductions you genuinely use. Common ones include contributions to EPF, PPF and ELSS, life insurance premiums, health insurance premiums, home loan interest and principal, HRA, NPS contributions and education loan interest.
  2. Calculate your tax under both regimes using the current year's slabs. The income tax department's online calculator is a good place to start.
  3. Compare the final tax payable, including cess and any rebate.
  4. Recheck every year, especially after a salary change, a new home loan, or a change in rent.

Who tends to benefit from each

These are general patterns, not rules:

The new regime often suits people who:

  • don't have a home loan or don't pay rent,
  • prefer not to lock money into tax-saving products, or
  • are early in their careers with few deductions.

The old regime may suit people who:

  • pay a home loan and claim interest and principal deductions,
  • receive HRA and pay significant rent, or
  • already make substantial tax-saving contributions they would make anyway.

Don't invest only to save tax

Tax-saving products should still fit your financial goals. An ELSS fund is an equity investment with market risk; a life insurance policy should be chosen for the cover it provides; a PPF ties up money for years. Choosing them only for a deduction can lead to products that don't suit you.

Switching between regimes

  • Salaried individuals without business income can generally choose a regime each year when filing their return.
  • People with business or professional income face restrictions on how often they can switch.

You can usually tell your employer your preferred regime at the start of the year for TDS purposes, and still make the final choice when filing — check the current rules for your situation.

Key takeaways

  • The new regime trades lower rates for fewer deductions; it's the default.
  • Compare both regimes with your actual numbers every year.
  • Choose investments for your goals first, and tax benefits second.
