CA Nikhil Gupta·Aug 2026·4 min readIncome Tax

For AY 2026–27, a belated return is ordinarily filed after the applicable section 139(1) due date but within the statutory belated-return window.

For AY 2026–27, a belated return is ordinarily filed after the applicable section 139(1) due date but within the statutory belated-return window. The exact portal deadline must be checked against the notified law and any CBDT extension in force on the filing date. Do not confuse a belated return with an updated return (ITR-U).

Legal or Computational Framework

AY 2026–27 relates to income earned in FY 2025–26 and remains governed by the Income-tax Act, 1961. A return filed after the applicable due date under section 139(1) is a belated return under section 139(4), subject to the statutory cut-off. Late filing can trigger section 234F fee, interest under sections 234A/234B/234C, delayed refund, and restrictions on carrying forward specified losses. A revised return is conceptually different: it corrects a return already filed. An updated return under section 139(8A) is a separate, later remedy with additional-tax conditions and exclusions.

Step-by-step method

  1. Identify the correct tax period, taxpayer category and statutory provision.
  2. Reconcile source records before using any calculator.
  3. Compute each legal component separately rather than using a single unexplained output.
  4. Check current official notifications, extensions and portal validations.
  5. Preserve the calculation and supporting documents.

Worked Example

Riya had salary income, bank interest and a small short-term capital loss for FY 2025–26. She missed her normal due date and filed later. Her return may be accepted as a belated return, but the capital loss carry-forward can be denied because the loss return was not furnished within the section 139(1) time. Current-year set-off, where otherwise permitted, must be analysed separately. She should calculate tax, interest and late fee before submission and preserve the filing acknowledgement.

What Generic Pages Miss

  • Treating the belated deadline as an automatic extension of the original due date.
  • Assuming every loss survives late filing.
  • Ignoring interest because tax was partly deducted at source.
  • Using ITR-U when a normal belated return is still legally available.
  • Failing to e-verify the return within the permitted verification period.

It may apply where the return is filed after the due date, subject to the statutory income-based cap and exceptions.
