GST Compensation Cess Credits: Legal Challenges, Judicial Approach & The Road Ahead

Background: FADA’s Challenge Before the Supreme Court

In December 2025, the Federation of Automobile Dealers Association (FADA) moved the Supreme Court questioning the constitutional and legal validity of a central government notification that effectively removed GST compensation cess on motor vehicles by prescribing a nil rate.

Under the earlier 2017 notification issued under the GST (Compensation to States) Act, specific motor vehicles attracted GST compensation cess, and registered persons could avail input cess credit against output cess liability. Once the cess was moved to a nil rate, a large volume of accumulated compensation cess credit in the electronic credit ledger became economically useless.

FADA’s petition focuses on this precise problem:

  • Accumulated compensation cess credits are stranded after cess on motor vehicles was reduced to nil.
  • No statutory or procedural route has been provided either for:
    • utilisation of such credits against other GST liabilities, or
    • refund of such credits to the assessee.

The grievance is not about the legislative competence to alter cess rates, but about the absence of a rational exit mechanism for credits that were lawfully earned and recorded under the earlier scheme. The dispute highlights a wider, recurring question in Indian indirect tax law – what happens to accumulated tax or cess credits when a levy is withdrawn, amended or structurally altered.

The issue is not new. Similar concerns have arisen across different indirect tax regimes – MODVAT, CENVAT, education cess, service tax – and now under GST. The judicial treatment of such credits offers important guidance for both courts and policy makers in the GST 2.0 phase.

Nature of Tax Credits: From MODVAT to GST

The GST (Compensation to States) Act and Cess Credits

The GST (Compensation to States) Act was enacted in 2017 to provide fiscal protection to States against loss of revenue due to GST implementation. To fund this compensation, a compensation cess was imposed on specified goods and services, including certain categories of motor vehicles.

Key features:

  • Compensation cess was levied over and above GST.
  • Cess paid on inputs and input services could be taken as credit and used to discharge output compensation cess on supplies of goods or services.
  • The design mirrored the broader GST input tax credit (ITC) architecture to prevent cascading of taxes.

Thus, compensation cess credit was meant to operate as a parallel credit stream, ring-fenced to compensation cess liability but still an economic right in the hands of the assessee.

Historical Roots: MODVAT and the Concept of Vested Credit

To understand present cess credit disputes, it is useful to revisit the MODVAT regime under the Central Excise law. MODVAT (Modified Value Added Tax) allowed manufacturers to claim credit of excise duty paid on inputs and set it off against duty payable on final products.

Under MODVAT:

  • A manufacturer sourcing raw materials from another manufacturer could avail credit of the excise duty embedded in the purchase price.
  • This input duty credit could then be adjusted against the excise duty on the final product, so that duty burden rested only on value addition at each stage.
  • The statutory basis for this mechanism was contained in Rules 57A to 57U of the Central Excise Rules, 1944, framed under Section 37 of the Central Excise Act, 1944.

The government later introduced Rule 57-F(4-A) in 1997, which mandated that all MODVAT credits lying unutilised as on a stipulated date in the accounts of manufacturers of tractors would automatically lapse. This triggered substantial litigation on whether such accumulated credits could be legally extinguished by subordinate legislation.

Eicher Motors: Credit as a Vested Right

The Supreme Court in Eicher Motors and Anr v. UOI (decision dated 28 January 1999) critically examined the nature of MODVAT credit. The court held:

  • Once duty has been paid on inputs, and MODVAT credit is duly entered in the assessee’s records as per the rules, the right to utilise that credit becomes a vested right.
  • Such credit is “as good as tax paid”, meaning it is not a mere concession but a substantive entitlement.
  • This entitlement crystallises when the inputs enter the manufacturing process and subsists until it is lawfully utilised against duty on final products.

By likening MODVAT credit to actual tax payment, the Supreme Court conferred strong legal protection on accumulated credits. Statutory amendments that retrospectively wipe out such rights were treated with caution.
