Section 128A waiver covers self-assessed tax under Section 73, subject to mandatory deadlines and limited voidness grounds.
Section 128A's waiver framework covers self-assessed tax where determination proceedings are initiated under Section 73. Direct recovery provisions for unpaid self-assessed tax do not exclude such demands, and an administrative circular cannot narrow the statutory waiver where the provision contains no express exclusion. Rule 164 imposes mandatory deadlines for filing applications and making required payments; deemed approval applies only to timely, substantively eligible applications not disposed of within the prescribed period. Waiver approvals in Form GST SPL-05 or SPL-06 become void only upon the specified failures to make additional payments, and cannot be separately invalidated on other grounds.
Issues: (i) Whether waiver under Section 128A extends to demands concerning self-assessed tax where proceedings were initiated under Section 73, notwithstanding Section 75(12) and Circular No. 238/32/2024-GST; (ii) Whether the time limits under Rule 164, including the deadline for filing a waiver application, are mandatory, and whether delayed disposal results in deemed approval; (iii) Whether an order approving waiver in Form GST SPL-05 may be subsequently declared void otherwise than under Rule 164(16) or Rule 164(17).
Issue (i): Whether waiver under Section 128A extends to demands concerning self-assessed tax where proceedings were initiated under Section 73, notwithstanding Section 75(12) and Circular No. 238/32/2024-GST.
Analysis: Section 128A is triggered by initiation of proceedings under Section 73. Section 75(12) permits direct recovery under Section 79 of unpaid self-assessed tax without prior determination, but does not preclude the revenue from initiating determination proceedings under Section 73. The wider non obstante clause in Section 128A, the absence of an express exclusion for self-assessed tax, and the express exclusion of erroneous refunds demonstrate that self-assessed tax cannot be impliedly excluded from the waiver scheme. Circular No. 238/32/2024-GST cannot restrict the statutory scope of Section 128A.
Conclusion: Where proceedings are initiated under Section 73, waiver under Section 128A is available even in relation to self-assessed tax; exclusions based solely on Section 75(12) or Circular No. 238/32/2024-GST are invalid. This is in favour of the assessee.
Issue (ii): Whether the time limits under Rule 164, including the deadline for filing a waiver application, are mandatory, and whether delayed disposal results in deemed approval.
Analysis: Rule 164 establishes a time-bound scheme for filing, scrutiny and disposal of waiver applications. Its prescribed consequence of deemed approval where no order is issued within the period under Rule 164(13) confirms that the stipulated time limits are integral to the scheme. The expression "may" in Rule 164(6) enables an eligible person to elect to apply; it does not render the three-month filing deadline discretionary. Deemed approval under Rule 164(14) operates only where the substantive conditions of Section 128A are satisfied. Substantial compliance may apply only to non-essential procedural lapses, not to belated filing or belated payment that defeats an essential condition of the scheme.
Conclusion: The time limits under Rule 164 are mandatory; a timely eligible application is deemed approved if no order is issued within the period under Rule 164(13), whereas belated applications or payments do not qualify for waiver. The deemed-approval finding is in favour of the assessee, and the mandatory filing and payment requirements are against the assessee.
Issue (iii): Whether an order approving waiver in Form GST SPL-05 may be subsequently declared void otherwise than under Rule 164(16) or Rule 164(17).
Analysis: Rule 164(16) and Rule 164(17) exclusively identify the circumstances in which waiver granted through Form GST SPL-05 or Form GST SPL-06 becomes void, namely failure to make specified additional payments. In those circumstances, voidness follows by operation of law. Neither Section 161 nor any other provision authorises the proper officer to issue a separate void order after approving the waiver for reasons outside those sub-rules.
Conclusion: An approval order in Form GST SPL-05 cannot be declared void except in the situations specified by Rule 164(16) or Rule 164(17). This is in favour of the assessee.
Final Conclusion: Waiver applicants satisfying the statutory conditions cannot be denied the amnesty benefit merely because the demand concerns self-assessed tax, and approvals or deemed approvals remain effective unless the narrowly prescribed grounds of voidness arise; applications or payments made beyond mandatory deadlines remain outside the scheme.
Ratio Decidendi: A statutory amnesty provision with a broad non obstante clause cannot be curtailed by implying an exclusion absent from its text or by an administrative circular; mandatory timelines governing the scheme bind both applicants and authorities, subject to the express consequence of deemed approval.
