In a significant ruling for contractors engaged in government works, the Karnataka High Court has affirmed that contractors are entitled to reimbursement of differential Goods and Services Tax (GST) amounts paid due to the transition from the Value Added Tax (VAT) regime to GST. The judgment underscores the State's obligation to bear such tax liabilities, providing clarity on contractual rights under public works agreements.
Background & Facts
The Dispute
The petitioner, a Class-I Registered Civil Engineer and Contractor, was awarded a works contract by the Karnataka Health System Development and Reform Project for "Repairs and Renovation Works (Balance Works)" to the existing TLH Building at Haliyal, Uttara Kannada District. The contract was executed during the transition from the VAT regime to the GST regime, which came into force on 01.07.2017. The petitioner claims that this transition imposed an additional tax liability, for which reimbursement was sought from the State.
Key Facts
- The petitioner executed the works contract under the VAT regime, which was later replaced by GST effective 01.07.2017
- The petitioner paid a differential GST amount of Rs. 6,20,826.56 due to the transition
- A representation dated 21.04.2026 was submitted to the respondents seeking reimbursement of the differential GST amount with 18% interest per annum from the date of remittance
- The respondents failed to act on the representation, leading to the filing of the present writ petition
Procedural History
- 21.04.2026: Petitioner submitted a representation (Annexure-B) to the respondents seeking reimbursement of differential GST
- No action taken by respondents: The representation remained unaddressed, prompting the petitioner to approach the High Court
- Writ Petition No. 104669 of 2026: Filed under Articles 226 and 227 of the Constitution of India seeking mandamus for reimbursement

- Interest at 18% per annum from the date of remittance till realization
- Disposal of the representation dated 21.04.2026 within a time frame fixed by the Court
The Legal Issue
The central question was whether the State is legally obligated to reimburse contractors for differential GST liability arising from the transition from the VAT regime to the GST regime, and if so, under what conditions and timelines.
Arguments Presented
For the Petitioner
- The petitioner contended that the transition from VAT to GST imposed an additional tax burden, which the State, as the beneficiary of the works contract, is liable to reimburse
- Reliance was placed on the precedent set in W.P.No.104908/2023, wherein the Karnataka High Court had held that the recipient of works contract services is liable to bear differential tax liability
- The petitioner argued that the inaction of the respondents in addressing the representation amounted to a violation of the petitioner's legal right to reimbursement
For the Respondents
- The respondents, represented by the Additional Government Advocate, did not contest the legal principle established in W.P.No.104908/2023
- However, they did not present any substantive arguments against the petitioner's claim for reimbursement
The Court's Analysis
The Court relied on its earlier decision in W.P.No.104908/2023, disposed of on 29.08.2023, which had settled the legal position on the issue. The Court observed:
"The controversy relating to liability to bear the differential tax consequent upon introduction of GST is no longer res integra. In an identical matter in W.P.No.104908/2023, disposed of on 29.08.2023, this Court has held that the recipient of the works contract service is liable to bear the differential tax liability arising on account of introduction of GST. This Court has further held that the State, its instrumentalities and Departments are under an obligation to reimburse the differential GST amount payable by the contractor."
The Court emphasized that the petitioner had already discharged the differential GST liability before the competent authority and that the respondents' inaction in reimbursing the amount had violated the petitioner's corresponding legal right. The Court held that the State, as the beneficiary of the work executed, is under a bounden duty to reimburse the differential GST amount.
The Verdict
The Court allowed the writ petition and passed the following directions:
- The respondents are directed to consider the representation dated 21.04.2026 and determine the differential GST amount payable to the petitioner in accordance with law
- Upon such determination, the respondents shall reimburse the differential GST amount of Rs. 6,20,826.56 to the petitioner within six weeks from the date of receipt of a certified copy of this order
- The reimbursement shall be confined to the differential tax liability attributable to the introduction of the GST regime and shall be subject to verification of records and calculations in accordance with law
