Individual taxpayers in India must avoid common filing errors to prevent tax notices and financial penalties during the current filing season [1, 2].
Accuracy in these filings is critical because mistakes can trigger government audits, delay the processing of refunds, or result in higher tax liabilities for the individual [3, 4, 5].
The filing season for Financial Year 2025-26, also known as Assessment Year 2026-27, began on April 1, 2026 [1]. Taxpayers have until July 31, 2026, to submit their returns via the Income Tax Department's online portal [1, 2]. Those who miss this deadline may face a penalty of ₹5,000 [6].
Experts have identified several recurring mistakes that lead to complications. These include selecting the wrong ITR form, failing to disclose all sources of income, and reporting incorrect deductions [3, 4]. Another frequent error involves mismatches between the filed return and Form 26AS, which tracks tax credits and TDS [4]. Improper reporting of capital gains is also a primary driver of tax notices [3, 4].
While different analysts highlight different sets of errors, some sources list seven critical mistakes [4] while others identify 10 common pitfalls [3]. Regardless of the number, the impact remains the same — a higher risk of regulatory scrutiny.
Precision in data entry is essential for a smooth process. Kelly Phillipserb said, "A wrong Social Security number, forgotten direct deposit info, or misunderstanding a credit, can cost you money or slow down the processing of your tax return" [5].
Taxpayers are encouraged to verify all disclosures against official documents before submission to ensure that the return matches the government's records [4].
“Missing this deadline could cost you ₹5,000”
The emphasis on precision for the FY 2025-26 cycle reflects the Income Tax Department's increasing reliance on automated data matching. When filed returns deviate from Form 26AS or other digital footprints, the system automatically flags the discrepancy, making manual verification and the use of the correct ITR form essential to avoid legal notices.
