The Income Tax Department is issuing notices to salaried individuals, primarily those who opted for the old tax regime, regarding discrepancies in deduction and exemption claims for AY 2025-26. Common issues include claims for bogus donations to RUPPs, incorrect PANs of donees, and errors in claimed amounts. Taxpayers are advised to review their Income Tax Returns and revise them by December 31, 2025, to avoid potential additional tax demands, interest, and penalties.
