The Customs, Excise & Service Tax Appellate Tribunal (CESTAT) Ahmedabad has clarified that a sub-contractor remains liable to pay service tax even when the main contractor has already discharged the liability, but emphasized that the CENVAT credit mechanism prevents double taxation. The Tribunal remanded the matter for recalculation of tax after granting the appellant the benefit of cum-duty valuation under Section 67(2) of the Finance Act, 1994.
Background & Facts
The Dispute
The appellant, Harikrishna Pankajkumar Gopani, operated as a sub-contractor providing construction services to M/s P R Patel & Co., Bhavnagar, during the period February 2016 to December 2016. The services rendered included construction of commercial and industrial buildings. The Revenue alleged that the appellant failed to pay service tax on invoices issued to the principal contractor, despite the latter having discharged service tax on the entire contract value. The Revenue relied on Master Circular No. 999.03 dated 23.08.2007, which explicitly stated that sub-contractors are taxable service providers irrespective of whether their services are used as inputs by the main contractor.
Key Facts
- The appellant rendered construction services to M/s P R Patel & Co. from February 2016 to December 2016.
- The total invoice value raised by the appellant was Rs. 12,08,54,245/-, as per the department’s calculation.
- The appellant claimed that the invoice value should be reduced by 1% profit margin of the principal contractor, resulting in a taxable value of Rs. 11,82,31,581/-.
- The appellant did not collect service tax separately from the principal contractor.
- The principal contractor had paid service tax on the entire contract value, including the portion subcontracted to the appellant.
- The appellant argued that demanding service tax from both parties amounted to double taxation.
- The appellant claimed eligibility for exemption under Entry 12A of Notification No. 25/2012-ST dated 20.06.2012, as amended by Notification No. 9/2016-ST dated 01.03.2016, but the Tribunal found the exemption inapplicable as the main contractor’s services were not exempt.
- The appellant also invoked Entry 29(h) of Notification No. 25/2012-ST, which exempts sub-contractors if the main contractor’s services are exempt.

The Parties' Positions
For the Appellant
- Argued that since the principal contractor had already paid service tax on the entire contract value, imposing liability on the sub-contractor resulted in double taxation.
- Relied on multiple CESTAT decisions from Delhi, Ahmedabad, Mumbai, and New Delhi holding that sub-contractors are not liable if the main contractor has paid.
- Invoked Entry 12A and Entry 29(h) of Notification No. 25/2012-ST to claim exemption.
- Contended that the extended period of limitation under Section 73(2) was not applicable as the issue involved an interpretational divergence among Tribunals prior to the Melange Developers ruling.
- Sought application of Section 67(2) of the Finance Act, 1994, to compute taxable value on a cum-duty basis.
For the Respondent
- Maintained that Master Circular No. 999.03 dated 23.08.2007 unequivocally established sub-contractor liability.
- Relied on the Larger Bench decision in Commissioner of Service Tax, New Delhi v. Melange Developers Pvt. Ltd. (2019-TIOL-1684-CESTAT-DEL-LB) to affirm that sub-contractors are taxable irrespective of the main contractor’s payment.
- Argued that the show cause notice was issued within the normal period of 30 months (as amended by Finance Act, 2016), hence limitation was not an issue.
- Rejected the applicability of exemption notifications as the main contractor’s services were not exempt.
- Cited Shri Rahul Agarwal v. Commissioner of CGST, Jabalpur (2025-TIOL-1368-CESTAT-DEL) to reinforce liability.
Relief Sought
The appellant sought:
- Dismissal of the service tax demand on grounds of double taxation and exemption.
- Application of Section 67(2) to reduce taxable value by excluding service tax component from invoice value.
- Cancellation of penalty and interest on grounds of no intent to evade.
- Confirmation that the demand was barred by limitation due to prior judicial divergence.
The Legal Issue
Is a sub-contractor liable to pay service tax on services rendered to a main contractor who has already discharged the service tax liability, and does the CENVAT credit mechanism negate the claim of double taxation? Further, is the appellant entitled to the benefit of cum-duty valuation under Section 67(2) of the Finance Act, 1994?
Arguments Presented
For the Appellant
The appellant relied on multiple CESTAT rulings, including Urvi Construction, JAC Air Services, and Viral Builders, which held that sub-contractors are not liable if the main contractor has paid. The appellant argued that the Revenue’s demand violated the principle of revenue neutrality and the statutory intent to avoid double taxation. The appellant further contended that the extended period of limitation under Section 73(2) could not be invoked due to a bona fide interpretational conflict among Tribunals prior to the Melange Developers decision. The appellant also invoked Section 67(2) to argue that the taxable value should be computed on a cum-duty basis, reducing the tax base by excluding the service tax component embedded in the invoice.
For the Respondent
The Respondent relied on the binding Larger Bench decision in Melange Developers, which overruled all prior contradictory rulings and held that sub-contractors are independent taxable entities under Section 68 of the Finance Act, 1994. The Revenue emphasized that the Master Circular of 2007 clarified that the nature of the service as an input does not alter its taxability. The Respondent further argued that the show cause notice was issued within the 30-month normal period under Section 73(1), as amended by the Finance Act, 2016, and that the exemption notifications did not apply because the main contractor’s services were taxable. The Respondent also contended that the CENVAT credit mechanism ensures no actual double taxation, as the main contractor can claim input credit.
The Court's Analysis
The Tribunal undertook a comprehensive review of the statutory framework under the Finance Act, 1994, and the CENVAT Credit Rules, 2004. It acknowledged the appellant’s reliance on prior decisions but held that the Larger Bench ruling in Melange Developers had conclusively settled the issue of sub-contractor liability. The Tribunal quoted the judgment directly:
"A sub-contractor would be liable to pay Service Tax even if the main contractor has discharged Service Tax liability on the activity undertaken by the sub-contractor in pursuance of the contract."
The Tribunal further explained that the CENVAT Credit Rules, particularly Rule 3 and Rule 3(4), provide a mechanism for input credit, ensuring that the tax paid by the sub-contractor is available as credit to the main contractor. This eliminates any actual double taxation, as the tax burden is ultimately borne only once through the supply chain.
The Tribunal rejected the appellant’s claim of exemption under Entry 12A and Entry 29(h) of Notification No. 25/2012-ST, noting that the exemption for sub-contractors is conditional on the main contractor’s service being exempt. Since the construction of residential complexes was not exempt during the relevant period, the exemption did not apply.
Regarding limitation, the Tribunal held that the show cause notice dated 30.08.2018 was issued within the 30-month normal period under Section 73(1), as the last ST-3 return for the period ending March 2016 was due on 25.04.2016. Hence, the extended period was not invoked, and the demand was time-barred.
Crucially, the Tribunal accepted the appellant’s argument under Section 67(2) of the Finance Act, 1994, which provides that where the gross amount charged includes service tax, the value of the taxable service must be computed by deducting the tax component. The Tribunal held:
"The appellant is entitled to the benefit of Section 67(2) and the taxable value must be recomputed accordingly."
The Tribunal emphasized that the Revenue must recalculate the demand by excluding the service tax component embedded in the invoice value, and that interest and penalty must be reassessed in light of the revised tax liability.
The Verdict
The appeal was disposed of by remand. The Tribunal upheld the liability of the appellant to pay service tax but directed the Adjudicating Authority to recompute the taxable value under Section 67(2) of the Finance Act, 1994, by deducting the service tax component from the invoice value of Rs. 12,08,54,245/-. The revised tax liability, interest under Section 76, and penalty under Section 78 shall be recalculated based on the corrected value. The appellant is directed to produce original invoices to substantiate the inclusion of service tax in the gross amount charged. The matter shall be decided within 8 weeks of receipt of this order.
What This Means For Similar Cases
Sub-Contractors Are Liable, But Not Double-Taxed
- Practitioners must now treat sub-contractors as independent taxpayers under Section 68, regardless of whether the main contractor has paid.
- The CENVAT credit mechanism under Rule 3(4) of the CENVAT Credit Rules, 2004, is the legal safeguard against double taxation - ensure input credit claims are properly documented.
- Arguments based on prior CESTAT rulings (e.g., Urvi Construction) are no longer valid after Melange Developers.
Cum-Duty Benefit Is Mandatory for Inclusive Pricing
- Where invoices show a lump-sum amount inclusive of service tax, Section 67(2) must be applied to compute the taxable value.
- Revenue authorities cannot ignore this provision; failure to do so renders the assessment legally defective.
- Practitioners should always request a breakdown of invoice value and tax component in audit notices and show cause notices.
Exemption Claims Require Strict Conditionality
- Exemptions under Entry 29(h) or 12A apply only if the main contractor’s service is exempt - verify the nature of the principal’s service before claiming exemption.
- Sub-contractors cannot rely on blanket exemptions; the exemption status of the main contractor must be proven with contract documents and tax payment records.
Limitation Periods Are Strictly Calculated
- The normal period for service tax demands is 30 months from the due date of the return or payment date.
- Extended period under Section 73(2) is only invoked where there is fraud or suppression - interpretational divergence does not qualify.
- Always verify the relevant date under Section 73(6) to determine limitation.
