Missed your ITR deadline? You still have 3 options but one may cost 70% more in tax
Those who discover errors after filing can opt for a Revised Return—even if the original was belated. This too must be filed by December 31 or before assessment.

Missed the income tax return (ITR) deadline or forgot to disclose income? Taxpayers still have three options—but one of them could cost up to 70% in additional tax, warns Sujit Bangar of TaxBuddy.com.
In a detailed post on LinkedIn, Bangar outlines three post-deadline paths available to Indian taxpayers: Belated Return, Revised Return, and the costliest—ITR-U (Updated Return).
The Belated Return, filed under Section 139(4), remains valid and is processed like a normal return. It's available until December 31 of the relevant assessment year, provided assessment hasn’t begun. But it comes at a cost: a late fee of ₹5,000 for incomes over ₹5 lakh, and ₹1,000 for those below, plus interest under Section 234A. Importantly, taxpayers forfeit carry-forward of most losses and several key deductions.
Despite these penalties, Bangar says it’s still “worth it” to file, as it validates TDS/TCS credits and avoids escalation to the more punitive ITR-U.
Those who discover errors after filing can opt for a Revised Return—even if the original was belated. This too must be filed by December 31 or before assessment.
The final and most punitive route is ITR-U, used when both previous deadlines are missed or unreported income is found later. While the Finance Act 2025 now allows filing within 48 months, this option carries heavy penalties: 25% to 70% additional tax on the total tax and interest due, depending on how late the correction is made.
“Treat ITR-U as a last resort, not a planning tool,” Bangar cautioned, noting that it cannot be used to reduce tax, declare losses, or claim refunds.
Taxpayers have been advised to act promptly: file belated returns if eligible, revise if necessary, and reserve ITR-U only for unavoidable lapses.
