2026 (7) TMI 519 - KARNATAKA HIGH COURT

At a Glance

• The obligation of a works contractor to discharge GST is determined under the applicable GST statute. The separate question whether the employer must bear or reimburse an incremental GST burden is governed by the contract between the contractor and the employer.
• A contractual clause stating that quoted rates are "inclusive of sales and other taxes" is materially relevant. It may affect whether the contractor assumed the risk of a subsequent tax incidence, subject to the construction of the agreement as a whole.
• For contracts spanning the transition to GST, a contract-wise reconciliation of pre-GST and post-GST work may be commercially and legally relevant. It does not, however, authorise alteration of statutory return, assessment, interest, penalty or limitation requirements.
• The reimbursement direction in 2026 (7) TMI 519 - KARNATAKA HIGH COURT is confined to the concerned employer. Tax authorities cannot be directed in a contractual reimbursement dispute to permit revised returns contrary to statute or to waive statutory interest, penalty or limitation.
• Where the contract supports a tax-adjustment mechanism, a supplementary agreement may document the revised GST-inclusive value. Reimbursement is not automatic merely because GST becomes payable; it depends upon the contractual allocation of tax risk and the resulting computation.

Background & Context

Works contracts that continued across the commencement of the GST regime gave rise to a recurring commercial dispute: the contractor remained statutorily liable to pay GST on taxable supplies, but the tendered price or schedule of rates may have been formulated under the earlier indirect-tax structure. Contractors consequently sought recovery of the additional or differential tax burden from government departments and other employers.

The dispute considered in 2026 (7) TMI 519 - KARNATAKA HIGH COURT concerned works or composite-supply contracts arranged in three broad settings: contracts tendered and executed before the GST transition; tenders issued before the transition but agreements entered thereafter using the earlier schedule of rates; and tenders issued after the transition but based on the earlier schedule of rates. The agreements placed before the court expressly stipulated that the contractor's quoted rates would be deemed to be "inclusive of sales and other taxes".

The contractors contended that the earlier schedule of rates did not factor central, State or integrated GST and that the GST levy created an incremental burden. The employer-side position, in substance, was that reimbursement could not be directed against the State generally and that the contractual terms controlled the allocation of the claimed amount.

The decision draws a necessary boundary between two legal relationships. The tax relationship is between the taxable person and the statutory tax administration. The reimbursement relationship is between the contracting parties. The first is controlled by the GST enactments; the second depends on contractual rights and obligations. Treating a contractual adjustment claim as though it modified the statutory GST framework is the central error corrected by the appellate decision.

Key Issues / Provisions

Works contract and composite supply

Section 2 of the Central Goods and Services Tax Act, 2017 defines a "works contract" in section 2(119) as a contract for specified activities concerning immovable property "wherein transfer of property in goods (whether as goods or in some other form) is involved in the execution of such contract". This definition identifies the statutory character of the underlying transaction; it does not itself determine which contracting party must ultimately absorb a tax-cost increase.

The same provision defines "composite supply" in section 2(30) as two or more taxable supplies, naturally bundled and supplied together in the ordinary course of business, one of which is a principal supply. "Consideration" in section 2(31) includes payment made or to be made "in respect of, in response to, or for the inducement of" a supply. These definitions matter because the contractual price, tax treatment and claimed adjustment must correspond to the actual supply and consideration structure.

Statutory levy and the person liable to pay

Section 9 of the Central Goods and Services Tax Act, 2017 provides in section 9(1) that central tax is levied on intra-State supplies, on the value determined under section 15, at notified rates, and "shall be paid by the taxable person". The provision establishes the statutory incidence and payment liability. It does not, by its own force, transfer the economic burden of GST to an employer under a works contract.

That distinction is decisive. A contractor may be liable to discharge GST as the taxable person, while its claim to recover the corresponding amount from the employer still requires an enforceable contractual basis, such as a tax-variation clause, change-in-law clause, price-adjustment provision, tender clarification, letter of award, or subsequent agreement.

Value of supply and additional contractual consideration

Section 15 of the Central Goods and Services Tax Act, 2017 states in section 15(1) that the value of supply is ordinarily the "transaction value", namely the price actually paid or payable where supplier and recipient are unrelated and price is the sole consideration. Section 15(2) includes, among other matters, an amount which the supplier is liable to pay in relation to the supply but which is incurred by the recipient and not included in the price actually paid or payable.

Accordingly, if a contractual reconciliation validly produces an additional sum payable by the employer for the supply, the parties must separately examine the GST consequences of that revised consideration under the statutory scheme. But valuation consequences cannot be assumed merely from a reimbursement demand; they follow from the true contractual entitlement and the applicable GST provisions.

Detailed Analysis

The governing distinction: statutory liability is not contractual reimbursement

In 2026 (7) TMI 519 - KARNATAKA HIGH COURT, the court held that entitlement to reimbursement of incremental tax paid or payable due to GST is "strictly a matter" between the contractors and their respective employers. The contract cannot alter the statutory scheme governing levy, assessment, recovery and enforcement of GST. The contractor's liability under the relevant GST enactment must therefore be determined strictly under statute, irrespective of the employer's reimbursement obligation.

The court consequently construed the reimbursement direction as operating only against the concerned employer, and not against tax authorities. It set aside the impugned directions insofar as they were directed to tax authorities or the State. More specifically, directions that would permit revised returns contrary to statute, or waive statutory limitation, interest or penalty, were held unsustainable. The practical result is carefully confined: a contractual tax-adjustment claim may survive for determination against the employer, but it cannot generate an exemption from statutory GST compliance.

Contract interpretation remains the starting point

The phrase "inclusive of sales and other taxes" was expressly present in the agreements considered in the appellate decision. Such wording is not inconsequential. It requires examination of whether the parties intended the quoted price to be all-inclusive notwithstanding future changes in tax burden, or whether other contractual material preserves a right to adjustment for a post-bid tax change.

The inquiry is necessarily document-specific. The agreement, bid conditions, schedules of rates, addenda, clarifications, letter of award, tax clauses and amendment provisions must be read harmoniously. A general inclusive-tax clause may have to be reconciled with a specific clause that permits equitable adjustment on a change in law. Conversely, a demand founded only on the fact that GST became payable cannot displace an unqualified contractual allocation of tax risk.

Contract-wise methodology as a reconciliation tool

The earlier decision in 2023 (6) TMI 93 - KARNATAKA HIGH COURT adopted a structured methodology for transitional works contracts. It contemplated identification of work executed and payments received under the earlier tax regime; determination of balance work undertaken after GST commencement; derivation of material and earlier-tax components; deduction of KVAT and service-tax components where applicable; addition of applicable GST; and set-off of eligible input tax credit against output GST for contractors assessed under regular VAT. The tax difference was then to be calculated contract-wise.

That methodology remains useful as a factual and commercial means of arriving at a revised GST-inclusive work value. It also recognises that a tax component is not necessarily a contractor's profit element. However, after the appellate ruling, the methodology cannot be understood as authority for judicially altering statutory GST procedures. Its relevance is confined to determining the inter se contractual adjustment between contractor and employer, subject to the contract and the applicable statutory framework.

The earlier decision also contemplated a supplementary agreement where the revised GST-inclusive value of the balance work exceeded the original agreement value, with reimbursement or recovery following the computation. A supplementary agreement is therefore an appropriate instrument where the parties agree that a contractual adjustment is due. It should record the basis of segregation, tax components excluded, GST applied, input-tax-credit treatment where relevant, revised value and the consequent payment adjustment.

Comparison with express tax-adjustment clauses

In 2023 (7) TMI 1292 - JHARKHAND HIGH COURT, reimbursement followed from the construction of an amended contractual clause, a pre-bid clarification and the letter of award. The expressions "affected transactions", "in totality" and "equitable adjustment" were held to cover the GST impact on all affected transactions, including indirect or bought-out items. The employer could not revive an exclusion that the amended clause had deleted. The authority illustrates that explicit contractual language may establish a broad reimbursement obligation despite general tax-risk disputes.

That decision also applied the change-in-law principle under section 64A of the Sale of Goods Act, 1930 in relation to the supply contract before it. Its utility in a works-contract dispute is contextual rather than automatic: entitlement must still arise from the governing contract and the nature of the transaction. Under the appellate decision, such contractual analysis cannot become a basis for directions that modify GST administration.

In 2023 (8) TMI 1531 - KARNATAKA HIGH COURT, the court directed reimbursement in a post-GST contract where the contractor had completed the work and the department had not acted on the representation. The decision demonstrates that, where the contractual setting and factual basis support recovery of the GST component, mandamus may be granted against the employer. Its application is necessarily subject to the appellate clarification that the direction runs against the employer alone and not the tax administration.

In 2019 (8) TMI 858 - MADRAS HIGH COURT, an ongoing pre-GST works contract was dealt with through a mechanism that estimated subsumed taxes, deducted that component from the original contracted value, added applicable GST and contemplated a supplemental agreement. The authority supports the proposition that a transitional contract need not be treated as having a permanently frozen value where the governing adjustment mechanism requires tax reconciliation. It does not dispense with the need to establish that the relevant contractual or administrative mechanism applies to the particular contract.

Practical Implications

• Contractors should segregate the claim into work performed before and after the GST transition and avoid presenting the full contract value as a single undifferentiated GST claim.
• Employers should examine the exact tax clause before accepting or rejecting reimbursement. Particular attention is required where the tender rate is described as inclusive of taxes, but other clauses provide for variation, equitable adjustment or change in law.
• A claim computation should identify the original agreed value, earlier-tax components, applicable GST on the post-transition component, eligible input tax credit where relevant, amounts already paid, and the net differential claimed or recoverable.
• Where adjustment is contractually justified, parties should document it through a supplementary agreement or other authorised contractual instrument. The revised value should be clearly identified as GST-inclusive or otherwise, as the case may be.
• GST returns, amendments, interest, penalty and limitation must be addressed under the relevant statute. A contractual reimbursement proceeding does not create a separate route for statutory relaxation.
• Representations and pleadings should seek relief from the contracting employer with precision. A request to compel tax authorities to administer GST contrary to statutory requirements is inconsistent with the appellate ruling.

Key Takeaways

Incremental GST on a works contract raises two distinct questions that must not be conflated. The first is the contractor's statutory tax liability, which arises and is administered under the GST enactments. The second is the economic incidence of that liability as between contractor and employer, which turns on the contract.

2026 (7) TMI 519 - KARNATAKA HIGH COURT confirms that courts may confine a reimbursement direction to the employer where the contract supports such a claim, but cannot use that dispute to revise the statutory GST regime or waive statutory interest, penalty or limitation. The earlier transitional decisions remain relevant for disciplined, contract-wise computation and for recognising express tax-adjustment clauses. Their use must, however, be consistent with the appellate boundary between contractual reimbursement and statutory tax administration.
