Early ITR Filers Face Revision Surge as Tax Data Updates Reveal Missed Income

Thousands of taxpayers who filed their Income Tax Returns (ITRs) early for Assessment Year 2026-27 may need to revise their returns as new financial information continues to be added to tax reporting systems after the initial filing process. Tax experts say the rise in revised returns is being driven by the Income Tax Department's increasingly comprehensive data collection mechanisms, which capture a wide range of financial transactions from multiple reporting entities.

According to Mrinal Mehta, Joint Secretary of the Bombay Chartered Accountants' Society (BCAS), the Annual Information Statement (AIS) has become a key factor behind the growing number of revised returns. The AIS consolidates information related to salary income, bank interest, dividends, securities transactions, mutual fund investments, property dealings, foreign remittances and other high-value financial activities. Since reporting entities continue updating information even after the financial year ends, taxpayers who file returns early may later discover additional entries that were not reflected at the time of filing.

Experts note that taxpayers often rely on partially updated AIS data while filing returns, only to find that banks, employers and other institutions submit fourth-quarter tax deduction and transaction details at a later stage. As a result, fresh information appearing in the AIS can create discrepancies between the filed return and the department's records, prompting taxpayers to submit revised returns to avoid future complications.

The situation is further complicated by the dynamic nature of both the AIS and the Taxpayer Information Summary (TIS). Unlike static documents, these records can continue to change as new information is reported. At the same time, the Income Tax Department's technology-driven scrutiny systems are increasingly capable of automatically detecting mismatches between taxpayer disclosures and third-party information, encouraging taxpayers to proactively correct errors before receiving notices from authorities.

For Assessment Year 2026-27, taxpayers can file a revised return under Section 139(5) of the Income Tax Act, 1961 until December 31, 2026, or before completion of assessment, whichever occurs earlier. The Finance Bill, 2026 has proposed extending this deadline until March 31, 2027, although revisions made after December may attract a prescribed fee. Beyond that period, taxpayers may still file an updated return under Section 139(8A) within 48 months, subject to additional tax liability.

Tax professionals advise taxpayers to avoid filing returns prematurely and instead reconcile information available in the AIS, TIS and Form 26AS with personal records such as Form 16, bank statements, brokerage reports, interest certificates and capital gains statements. Careful verification before filing can help reduce reporting errors, minimise the need for revisions and lower the risk of future scrutiny from tax authorities.
