Can I claim Standard Deduction (₹50,000) under the New Regime for FY 2025-26?

Yes, since FY 2023-24, the Standard Deduction of ₹50,000 is available under the New Tax Regime for salaried individuals, making it more attractive for middle-income taxpayers. This is in addition to the increased basic exemption limit.

What is the ITR filing deadline for FY 2025-26?

The ITR filing deadline for non-audit cases for FY 2025-26 (AY 2026-27) is July 31, 2026. Late filing incurs a ₹5,000 penalty (or ₹1,000 if income is below ₹5 lakh) under Section 234F.
