Income Tax Old Regime Vs New Regime for AY 2026-27: The income tax return (ITR) filing for the assessment year 2026-27 is going on, with only 10 days left for the July 31 deadline. Though the return filing has
been made simple on the e-filing portal, the main task is your tax computation and the decision between the old and new tax regimes.
The new tax regime was announced in the Union Budget 2020-21 on February 1, 2020, and became effective from April 1, 2020. This regime was introduced as a relaxed income tax system with lower tax rates in exchange for giving up most exemptions and deductions (such as HRA, LTA, Section 80C, etc.). The old tax regime has higher tax rates but comes with various deductions and exemptions.
ITR Filing Last Date: Who Must File Their Income Tax Return by July 31?
The new tax regime was made the default tax regime from April 1, 2023. However, taxpayers also have the option to choose the old tax regime at the start of the financial year (by informing their employer) or during ITR filing. Here are the income tax rates, slabs, deductions, exemption limits and rebates under both old and new tax regimes.

Income tax old regime vs new regime: Which one is better for you?
A Delhi-based CA said, “Taxpayers claiming substantial deductions and exemptions may benefit more under the old regime. However, taxpayers with limited deductions and exemptions generally benefit more under the new regime. As a practical measure, taxpayers should compute their tax liability under both regimes before filing their income tax return (ITR) on the official income tax portal at https://eportal.incometax.gov.in/iec/foservices/#/TaxCalc/calculator.”
