Transitional input tax credit conditions and filing deadline upheld as valid limits on GST credit claims.

Transitional input tax credit under the GST enactments is a statutory concession that may validly be made subject to prescribed declarations and a filing deadline. The second proviso to section 140(1) was upheld because it did not extinguish credit permanently, but only postponed the benefit until the required statutory forms were furnished, leaving the claim refundable once substantiated. Rule 117 was also held intra vires because the rule-making power under the Act allowed a prescribed time limit for orderly transition, finality of claims and effective tax administration. The constitutional and ultra vires challenges were rejected.

Issues: (i) Whether the second proviso to section 140(1) of the GST enactments, which withholds transitional credit linked to inter-State sales, branch transfers and export sales unless prescribed declarations are produced, is unconstitutional; (ii) Whether rule 117 of the GST Rules, prescribing the time limit for filing TRAN-1, is ultra vires the Act or liable to be treated as merely directory.

Issue (i): Whether the second proviso to section 140(1) of the GST enactments, which withholds transitional credit linked to inter-State sales, branch transfers and export sales unless prescribed declarations are produced, is unconstitutional.

Analysis: The transitional provision was read as continuing the earlier statutory scheme under the Central Sales Tax regime, where concessional treatment itself depended on production of prescribed forms. The proviso did not extinguish the credit permanently; it only postponed the benefit until the statutory declarations were furnished, and the corresponding amount remained refundable under the existing law once the claim was substantiated. On that construction, no vested or accrued right was taken away. The challenge based on lack of machinery also failed because the provision was treated as an enabling transitional credit provision subject to conditions, not as a charging provision.

Conclusion: The challenge to the second proviso to section 140(1) failed and the provision was upheld.

Issue (ii): Whether rule 117 of the GST Rules, prescribing the time limit for filing TRAN-1, is ultra vires the Act or liable to be treated as merely directory.

Analysis: Section 164 confers wide rule-making power to make rules for carrying out the Act and for matters required to be prescribed. Rule 117 was held to be within that power because the transitional credit scheme under section 140 necessarily required a prescribed time frame for orderly migration, finality of claims and effective tax administration. The Court held that input tax credit is a statutory concession subject to conditions and that the time limit was not a mere technical formality. Given the scale of the GST transition, treating the time prescription as directory would undermine certainty in revenue collection and create unending claims.

Conclusion: Rule 117 was held to be intra vires and the time limit was not treated as merely directory.

Final Conclusion: The transitional credit restrictions and the filing deadline were both sustained, and the constitutional and ultra vires challenges were rejected.

Ratio Decidendi: Transitional input tax credit is a statutory concession that may validly be subjected to prescribed conditions and a time limit under delegated legislation authorised by the parent enactment, and such a prescription is constitutionally sustainable where it serves certainty, finality and efficient tax administration.
