Section 292BA and DIN Irregularities: Litigation Risks and Strategy After Finance Bill 2026

Finance Bill 2026, unveiled with the Union Budget 2026, does more than tweak tax rates or modify TDS / STT provisions. It introduces a series of procedural and jurisdictional amendments aimed at directly addressing ongoing litigation, especially where courts have taken a strict view of departmental non-compliance with internal instructions or timelines.

Among the key amendments proposed are:

  • Clarifications on section 144C dealing with DRP procedures and corresponding timelines in sections 153 and 153B.
  • Time-limit related clarifications for section 92CA (TPO orders).
  • A new section 292BA to address the impact of Document Identification Number (DIN) errors on the validity of assessments.
  • A new section 147A to clarify who is the “Assessing Officer” in the context of sections 148 and 148A, especially in faceless regimes.

CBDT (Income Tax–Judicial), via communication dated 02.02.2026 bearing F. No. 279/Misc/M-13/2026-ITJ, has already instructed departmental representatives and standing counsels to seek adjournments in pending matters impacted by these proposed amendments. The clear objective is to avoid final adverse decisions until Parliament enacts these “clarificatory” provisions.

This write-up focuses on DIN-validity disputes and the proposed insertion of section 292BA, which is intended to operate retrospectively from 01.10.2019 and significantly alter the litigation landscape on this issue.

2. DIN Framework: What It Required and Why It Became Litigious

2.1 Essence of the DIN mechanism

DIN was conceptualised as a system-generated unique identification number for departmental communications, introduced to:

  • Create a verifiable electronic audit trail;
  • Prevent non-system, off-record communications; and
  • Improve transparency and internal accountability.

The regime was implemented via CBDT Circular No. 19/2019 dated 14.08.2019, making DIN a central control tool for all key communications with the assessee.

2.2 CBDT Circular No. 19/2019 – mandatory and strict in its terms

The circular, along with accompanying press releases, did three critical things that fuelled a wave of litigation:

  1. Mandatory DIN requirement

    • DIN was made compulsory for a broad class of communications, including notices, assessment orders, summons, letters and other specified communications issued by the Income Tax Department.

  2. Limited exceptions with tight conditions
    Manual (non-DIN) communications were permitted only in narrowly defined scenarios, such as:

    • Technical difficulties with the system;
    • Situations involving confidentiality; or
    • Other specified exigencies.

    Even in these situations, officers were required to:

    • Record reasons in writing;
    • Obtain approval from prescribed authorities; and
    • Later regularise the communication by generating a DIN within a prescribed period and following the exact procedure laid down in the circular.

  3. Consequences clause – communications without DIN “deemed never issued”
    The circular categorically provided that any communication which:

    • Did not bear a DIN, and
    • Did not fit within the exception and regularisation framework,

    would be treated as:

    • “invalid and shall be deemed to have never been issued.”

This “non-est” declaration converted DIN lapses into a potent ground of challenge. Where assessees could demonstrate that a notice or order was issued in breach of the DIN circular, they argued that it simply did not exist in law.

3. How DIN Defects Arose in Real Cases

From 01.10.2019 onwards, the following types of fact patterns commonly gave rise to disputes:

  • DIN generated but not appearing on the face of the document
    For instance, the departmental system may have generated a DIN, but the PDF output or printed order did not display it due to template or formatting issues.

  • DIN only on a separate communication, not on the order itself
    Cases where:

    • DIN was visible on a covering letter or portal message,
    • But the assessment order PDF (or its signed pages) did not reproduce the DIN.

  • Incorrect, truncated, or mismatched DIN

    • DIN printed partially;
    • Wrong DIN quoted;
    • DIN on the first page but absent where signature/dispatch details appeared.

  • Invocation of “technical difficulties” without following the exception protocol

    • Officers issued communications without DIN;
    • No proper internal approval, reason recording, or later regularisation was done, contrary to Circular No. 19/2019.

Given the explicit “deemed never issued” wording, several benches concluded that such lapses were not minor clerical issues, but fatal jurisdictional defects.

4. Judicial Response to DIN Non-Compliance (Pre–Finance Bill 2026)

4.1 Delhi High Court – CIT (International Taxation) v. Brandix Mauritius Holdings Ltd. (2023)

In CIT (International Taxation) v. Brandix Mauritius Holdings Ltd. (2023), the Delhi High Court:

  • Held that an assessment order communicated without complying with the DIN mandate of the circular could be set aside;
  • Declined to allow the Revenue to invoke cure provisions such as section 292B to save the order where the circular’s requirements were not met.

The case underscored that CBDT’s own binding circulars could not be casually disregarded, especially where they declared non-compliant communications as non-est.

The matter also reached the Supreme Court via SLP, with interim developments being closely watched, signalling that the issues raised were systemically significant.
