Key Takeaways

The new tax regime offers lower slab rates but removes most deductions like Section 80C and 80D under Section 115BAC of the Income Tax Act. The new regime is set as the default regime for individual taxpayers as per the Income Tax Department portal.
The old regime allows deductions up to ₹1,50,000 for eligible investments like PPF, ELSS, and life insurance premiums, which directly reduce your taxable income.
The eligible resident individuals can claim a rebate that can reduce their tax liability to zero if their taxable income falls within the prescribed limit under the new regime.

A tax regime calculator helps you compare your income tax liability under both tax regimes using the latest slab rates. It works like an indian income tax calculator, where you enter your income and deductions to see which option results in lower tax.

You can also use tools like the ClearTax tax calculator or any old vs new tax regime calculator online to quickly check the difference. Many professionals also prefer using an old vs new tax regime calculator Excel 25 26 sheet, for advanced planning.

Bonus Tip: A recent article shows taxpayers earning ₹15,00,000 - ₹25,00,000 could save more under the old tax regime if draft 2026 rules increase allowance limits for HRA, loans, and education benefits.
