Section 158A Income Tax Act: Identical Question of Law and Section 375 (2025)

Updated: 26 October 2026

Section 158A of the Income-tax Act, 1961 provided a way for an assessee to avoid repeatedly litigating the same question of law for different assessment years when that question was already pending before the High Court or Supreme Court in the assessee's own case. From 1 April 2026, the corresponding provision is Section 375 of the Income-tax Act, 2025, subject to applicable transition and savings provisions.

Current-law update (26 October 2026): For proceedings governed by the Income-tax Act, 2025, consult Section 375, Rule 194 of the Income-tax Rules, 2026 and Form 117. Section 158A remains relevant when examining proceedings governed by the earlier Act. The two regimes should not be treated as interchangeable without checking the relevant tax year and savings provisions.

Purpose and meaning of Section 158A

Chapter XIV-A of the 1961 Act dealt with avoiding repetitive appeals. A question of law is a legal issue about interpreting or applying law, rather than merely a dispute about facts. An identical question of law must be the same legal issue in the assessee's own cases for different assessment years; a broadly similar dispute alone may not qualify.

The relevant case is the proceeding before the Assessing Officer or appellate authority in which relief from repetitive litigation is requested. The other case is the assessee's proceeding for another year where the identical legal question is already pending before the High Court or Supreme Court in the specified manner.

Conditions for making a declaration

  1. The assessee must have a question of law in a pending assessment or appellate proceeding.
  2. The same legal question must arise in the assessee's own case for another assessment year and be pending before the High Court or Supreme Court in a qualifying reference or appeal.
  3. The assessee must file the prescribed, verified declaration agreeing not to raise that legal question again in the relevant case if the authority agrees to apply the final ruling in the other case.
  4. The Assessing Officer or appellate authority must be satisfied that the questions of law are identical and admit the claim in writing.

Section 158A explained subsection by subsection

Subsection (1): Declaration and undertaking

The assessee could furnish the prescribed declaration to the Assessing Officer or appellate authority. The undertaking was tied to applying the final decision in the other case and refraining from a separate appeal on the same question in the relevant case. The earlier provision referred to sections 256, 257, 260A and 261 of the 1961 Act.

Subsection (2): Report and hearing

When the declaration was made to an appellate authority, that authority was required to obtain a report from the Assessing Officer. If the Assessing Officer requested an opportunity of hearing, it had to be given.

Subsection (3): Admission or rejection

The authority could admit the claim if satisfied that the legal question was identical, or reject it otherwise. The decision had to be recorded in a written order.

Subsection (4): Disposal and restriction on appeal

After admission, the relevant proceeding could be disposed of without waiting for the final judgment in the other case. The assessee could not separately appeal the admitted question of law in the relevant case.

Subsection (5): Giving effect to the final ruling

When the ruling in the other case became final, the authority was required to apply it to the relevant case and amend the earlier order where necessary.

Subsection (6): Finality of the admission decision

The written order admitting or rejecting the claim under subsection (3) was final and could not be challenged through an appeal, reference or revision under the Act.

Statutory explanations and scope

For this provision, appellate authority included the specified first appellate authorities and the Income Tax Appellate Tribunal, as provided in the version applicable to the relevant period. A case included proceedings for assessment of total income and for imposition of penalty or fine. The text and names of appellate authorities have changed through amendments, so the operative version should be checked for the relevant proceeding.

Section 375 of the Income-tax Act, 2025

Section 375 carries forward the assessee-driven mechanism for avoiding repetitive appeals. It covers an identical question of law in the assessee's own case for another tax year, pending in a qualifying High Court or Supreme Court proceeding. It requires a declaration and provides for the authority's decision, disposal of the relevant case, and subsequent application of the final ruling. The detailed wording and qualifying proceedings must be read in Section 375 itself.

The updated prescribed declaration is Form 117 under Rule 194 of the Income-tax Rules, 2026. The earlier framework used Form 8 under Rule 15A of the Income-tax Rules, 1962. Filing the declaration is optional, but acceptance has significant consequences for appeal rights concerning the identical legal issue.

Practical illustration

Suppose a taxpayer's deduction claim raises the same interpretation of a statutory provision for two different years. An appeal concerning the first year is pending before the High Court, while the second year's proceeding is pending before an appellate authority. If the statutory conditions are met, the taxpayer may submit the prescribed declaration for the second year, undertake to accept the eventual decision on that question, and avoid separately litigating it. Whether the issues are truly identical must be decided by the competent authority.
