Differential GST reimbursement for post-transition contract work cannot depend on an uncertified departmental condition absent statutory support.
For works performed after the GST transition date under pre-GST contracts, differential GST may be reimbursable where post-transition work is separately computed and its GST-inclusive value exceeds the original contract value. The notes state that the public employer, as service recipient, bears the admissible differential tax burden. Statutory GST invoices, accounts, returns, audited records and Chartered Accountant certificates are identified as sufficient evidence of GST discharge. No CGST, State GST or subordinate-law provision is described as requiring a contractor to obtain a jurisdictional GST officer's certificate; imposing that additional condition for reimbursement is characterised as unsupported by law or contract.
Issues: (i) Whether production of a GST departmental certificate could be required as a precondition to reimbursement of differential GST; (ii) Whether a contractor was entitled to reimbursement of differential tax for work executed after the GST transition under a pre-GST contract; (iii) Whether GST returns, Chartered Accountant certificates and audit reports sufficiently established discharge of GST liability.
Issue (i): Whether production of a GST departmental certificate could be required as a precondition to reimbursement of differential GST.
Analysis: No provision in the Central Goods and Services Tax Act, State GST law, or subordinate legislation required a contractor to obtain a certificate from the jurisdictional GST officer for release of differential tax. The prescribed compliance mechanism consists of statutory invoicing, accounts and return filings; imposing an additional certificate requirement created an arbitrary burden unsupported by law or contract.
Conclusion: The requirement of a GST departmental certificate is legally unsustainable and is decided in favour of the assessee.
Issue (ii): Whether a contractor was entitled to reimbursement of differential tax for work executed after the GST transition under a pre-GST contract.
Analysis: Supplies and works executed after 01.07.2017 attracted GST under the transitional provision notwithstanding that the work order and original estimate arose under the VAT and service-tax regime. The applicable directions for transition-period works require separate computation of pre-GST and post-GST work, with reimbursement by the employer where the GST-inclusive value of post-GST work exceeds the original contract value. The public employer, as service recipient, bore the differential tax burden.
Conclusion: The contractor is entitled to reimbursement of the admissible differential GST for work executed after 01.07.2017, in favour of the assessee.
Issue (iii): Whether GST returns, Chartered Accountant certificates and audit reports sufficiently established discharge of GST liability.
Analysis: The statutory returns, audited financial records and Chartered Accountant certification collectively evidenced discharge of GST liability. In the absence of a statutory requirement for further departmental certification, these documents were sufficient proof of compliance.
Conclusion: GST returns, Chartered Accountant certificates and audit reports are sufficient to establish discharge of GST liability, in favour of the assessee.
Final Conclusion: The differential GST arising from the statutory transition is recoverable by the contractor from the public employer, and the unsupported certification condition cannot obstruct payment.
Ratio Decidendi: For works performed after the GST appointed day under a pre-GST contract, the employer must reimburse the admissible differential GST where statutory compliance is established through prescribed returns and supporting records; a departmental certificate not mandated by law cannot be insisted upon.
