Taxability of Works Contract Services to GHMC, South Central Railway, I & CAD Department under CGST & SGST Acts

The applicant's supply of works contract services to Greater Hyderabad Municipal Corporation (GHMC) and South Central Railway was found taxable at 18% under both CGST & SGST Acts. However, services provided to the I & CAD department were exempt to the extent of grants received. Tax liability for works contract services procured from third parties for GHMC, I & CAD department, and South Central Railway was also determined to be taxable at 18%.

ISSUES PRESENTED AND CONSIDERED

1. Whether supplies of transmission-line and related construction works effected by the supplier to a municipal corporation (GHMC) constitute "pure services" exempt under the notification for services to Government/local authorities, or are works contract/composite supplies taxable under the works-contract classification, and the applicable rate.

2. Whether works contract services procured by the supplier from third-party turnkey contractors (back-to-back) for supply to GHMC fall within the concessional entry (reduced rate) applicable to certain government works, or are taxable under the general works-contract entries, and the applicable rate.

3. Whether supplies of transmission/power infrastructure to the Irrigation & CAD department (I & CAD) by the supplier qualify for exemption under the "service by a Government Entity against grants" entry, and whether works procured from third parties for supply to I & CAD are taxable, and at what rate.

4. Whether supplies of general construction services (long-distance/overland electric power lines, transformer stations, related works) to a railway authority are taxable under the reduced specific entries or under the general construction entry, and the applicable rate; and whether corresponding back-to-back contractor supplies are similarly classifiable and taxable.

ISSUE-WISE DETAILED ANALYSIS

Issue 1: Classification of supplier's works to municipal corporation (GHMC) - exemption vs works contract; applicable rate.

Legal framework: Notification classifying construction/works-contract services into specific heads (including service codes 995423, 995424) and separate notifications providing exemptions/reduced rates for services to Central/State/Local authorities where the supply is a "pure service" not involving works contract or composite supplies involving supply of goods.

Precedent treatment: The Court invoked the general canon that specific provisions prevail over general ones (referencing established authority on construction of statutes), applying it to competing notification entries.

Interpretation and reasoning: The authority examined the contract estimate showing significant material component (goods) in the supplies to GHMC (detailed cost breakup). Because the supply involved substantial goods and constituted a works contract/composite supply rather than a "pure service", it fell outside the exemption reserved for pure services to government/local authorities. The works were classifiable under service tariff code 995423/995424 (general construction services for electric power lines/transformer works). The tributary scheme places such general construction services under the residual/general entry taxed at the rate provided for works contracts (aggregate 18%: 9% CGST + 9% SGST). The Court applied the rule that specific concessional entries cannot be extended to services not expressly covered by those entries.

Ratio v. Obiter: Ratio - where a supply to a local authority involves substantial supply of goods such that it is a works contract/composite supply, it is not eligible for the exemption reserved for pure services to government/local authorities; such general construction services fall under the tariff codes 995423/995424 and attract the works-contract rate.

Conclusion: Supplies by the supplier to GHMC are not exempt; taxable at a combined rate of 18% (9% CGST + 9% SGST).

Issue 2: Taxability and rate of works procured from third-party turnkey contractors (back-to-back) for supply to GHMC - applicability of reduced entry 3(vi) vs general entry.

Legal framework: Notification entries distinguishing specific construction works eligible for concession (entry 3(vi) / related substitutions) from other general construction services (residual entry 3(vii) or retained entries) and the principle of specific provision prevailing over general.

Precedent treatment: The authority relied on the established interpretive principle favouring specific statutory language over general classifications.

Interpretation and reasoning: Entry 3(vi) (and its substituted formulations) lists narrowly defined construction services (civil structures meant predominantly for non-commercial use, educational/clinical/art establishments, specified residential complexes). The Court found that electrical transmission/line works (service codes 995423/995424) are not within that specific enumeration. Accordingly, contractor supplies for these works do not qualify for the concessional rate under entry 3(vi), and instead fall within the general construction service entry taxable at the works-contract rate. The alternative textual reading urged by the applicant (giving broad effect to "other than for commerce, industry, or any other business or profession") was rejected because the specific list controls; once an activity is outside the specific entry, other qualifications do not expand its scope.

Ratio v. Obiter: Ratio - back-to-back contractor supplies for electrical transmission/related works that are not specifically enumerated in the concessional entry are subject to the general works-contract classification and corresponding rate.

Conclusion: Works procured from third-party contractors for supply to GHMC are taxable at 18% (9% CGST + 9% SGST).

Issue 3: Supplies to Irrigation & CAD (I & CAD) - applicability of exemption under "service by a Government Entity against grants" and taxability of third-party contractor supplies.

Legal framework: Notification providing exemption for "service by a Government Entity to Central/State/Local authority or any person specified ... against consideration received ... in the form of grants" (entry 9(c) of the relevant notification).

Precedent treatment: Applied statutory wording of the grants-based exemption.

Interpretation and reasoning: The supplier is a Government entity. Where supplies are made to State Government/local authorities and are financed by grants (consideration received in the form of grants for those supplies), those specific supplies are exempt to the extent the grants cover them. The exemption is therefore supply- and grant-specific. However, where the supplier engages third-party contractors on a back-to-back basis and the procured works do not fall within the grants-covered exempt supply (i.e., are not the subject of grants or are composite works involving goods beyond the scope of the grant exemption), those contractor supplies remain taxable under the general works construction entry.

Ratio v. Obiter: Ratio - supplies by a Government entity are exempt under the grants-based entry only to the extent the supply is made against grants; corresponding procured contractor services are taxable unless they are supplied under the same grant-funded, exempted supply.

Conclusion: Supplies by the Government entity to I & CAD are exempt to the extent grants are received against those supplies; third-party contractor supplies procured by the entity for supply to I & CAD are taxable at 18% (9% CGST + 9% SGST) unless they fall within the scope and extent of the grant-funded exemption.

Issue 4: Supplies to Railway authority - classification of general construction services for long-distance/overland electric power lines and tax rate; treatment of back-to-back contractor supplies.

Legal framework: Notification entries classifying general construction services (including long-distance pipelines, communication and electric power lines, transformer stations) under a general heading (service code 995423, etc.) and providing the applicable works-contract rate.

Precedent treatment: Application of the classification scheme and earlier interpretive conclusions regarding specific vs general entries.

Interpretation and reasoning: The works undertaken for the railway fall squarely within the general construction services for communication and electric power lines and related works (service code 995423). Such services are not included in the narrow concessional entries for specific civil or social infrastructure and are therefore taxable under the general works-contract entry. Likewise, contractor supplies executed on a back-to-back basis for these railway works are similarly classifiable and taxable.

Ratio v. Obiter: Ratio - general construction services for long-distance/overland/submarine electric power lines and related works are taxable as general construction services under the works-contract classification; corresponding contractor supplies are taxable likewise.

Conclusion: Supplies to the railway authority are taxable at a combined rate of 18% (9% CGST + 9% SGST); back-to-back contractor supplies procured for such works are taxable at the same rate.

Cross-References and Synthesized Principles

1. Specific concession entries for government/local-authority works must be given effect according to their explicit scope; works not expressly enumerated (notably electrical power lines, transformer stations and similar general construction services under service codes 995423/995424) do not qualify for such concessions and fall under the residual/general works-contract entry.

2. A supply involving substantial provision of goods and material is a works contract/composite supply, not a "pure service"; the presence of significant material components excludes applicability of exemptions limited to pure services.

3. Exemption that depends on consideration received in the form of grants applies only to supplies made against such grants and only to the extent of those grants; non-grant-funded or contractor-procured components remain taxable in absence of explicit coverage.

Final Rulings (expressed in legal conclusions)

1. Supplies of works contract services to GHMC are not exempt; taxable at 18% (aggregate).

2. Works contract services procured from third-party contractors for supply to GHMC are taxable at 18% (aggregate).

3. Supplies to I & CAD by the Government entity are exempt only to the extent grants are received for those supplies; otherwise taxable. Procured contractor works for supply to I & CAD are taxable at 18% unless covered by grant-funded exemption.

4. Supplies of general construction services to the railway authority, and contractor supplies procured for that purpose, are taxable at 18% (aggregate).
