GST exemption for government works contracts under Notification 12/2017 doesn't apply to sub-contractors serving main contractors

The AAR Telangana ruled that GST exemption available to main contractors under Notification No. 12/2017-Central Tax (Rate) for works contracts with goods supply value less than 25% to government entities does not extend to sub-contractors providing services to such main contractors. The Authority held that exemption notifications must be strictly construed, and since the notification does not specifically mention sub-contractor supplies unlike Notification 11/2017, the exemption cannot be extended to taxable persons supplying services to exempted works contractors without explicit provision under Section 11(1) of CGST Act.

1. ISSUES PRESENTED AND CONSIDERED

1. Whether supply of services by a sub-contractor to a main contractor, in relation to operation & maintenance of water supply projects commissioned by State authorities, falls within the exemption under Notification No.12/2017 (as amended by Notification No.2/2018) providing nil-rating where value of goods is not more than 25% and the supply is to Central/State/Local Government in relation to functions entrusted under Articles 243G/243W.

2. Whether the procurement by a main contractor (from a sub-contractor) and the main contractor's supply to the Government constitute two independent taxable events under the CGST Act (i.e., whether exemption applicable to main contractor can be extended to its procurement).

3. If exemption does not extend to the sub-contractor's supply, what is the applicable GST rate on the sub-contractor's supplies.

2. ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Applicability of Notification No.12/2017 (as amended) to sub-contractor's supply

Legal framework: Notification No.12/2017 (Rate) as amended by Notification No.2/2018 introduced an entry (3A) exempting works contracts where value of supply of goods does not exceed 25% when the supply is made to Central/State/Local Government for activities related to functions under Articles 243G/243W. The exemption under Sec.11(1) CGST is subject to conditions in the notification. Notification 11/2017 (as amended) separately refers to rates for main contractors and sub-contractors where services are procured by the main contractor in relation to work entrusted by Government bodies.

Precedent treatment: Authorities emphasise strict construction of exemption notifications (citing Hemraj Gordhandas v. H.H. Dave; CCE v. Ginni Filaments and multiple Supreme Court decisions applying strict interpretation in taxation). The earlier Sales Tax jurisprudence (State v. Larsen & Toubro) treated contractor and sub-contractor as constituting a single transfer of property in goods to the contractee; that principle was considered but distinguished.

Interpretation and reasoning: The notification's language confines the exemption to supplies "made to" Government/Local Authority. The notification does not expressly include supplies made by sub-contractors to main contractors (i.e., procurement by main contractor) within the scope of Entry 3A. By contrast, Notification 11/2017 expressly contemplates sub-contractors for rate parity, indicating the statutory scheme treats sub-contractor supplies as distinct unless expressly covered. Given the change in taxable event under GST (supply of service rather than transfer of property in goods), the AAR reasons that earlier Sales Tax single-sale reasoning does not automatically carry over. Tax exemption notifications must be read narrowly; there is no textual basis to extend Entry 3A to supplies by sub-contractors to main contractors in the absence of an express inclusion under Sec.11(1).

Ratio vs. Obiter: Ratio - Exemption under Entry 3A does not extend to supplies made by a sub-contractor to a main contractor unless such supplies are expressly covered by notification; strict construction governs exemptions. Obiter - Historical Sales Tax single-sale reasoning (Larsen & Toubro) is discussed and distinguished as not determinative under GST because the taxable event differs.

Conclusion: The sub-contractor's supply to the main contractor is not covered by Notification No.12/2017 (as amended) Entry 3A; therefore the nil-rating under that entry is not available to the sub-contractor in the absence of an express notification under Sec.11(1) covering such procurement.

Issue 2 - Whether procurement by main contractor and main contractor's supply are independent taxable events

Legal framework: Under CGST, the taxable event is supply of goods or services. The scheme and amended notifications treat supplies by sub-contractors to main contractors as distinct taxable supplies; Notification 11/2017 (as amended) expressly contemplates sub-contractor supplies for rate parity, indicating legislative recognition of separate taxable events.

Precedent treatment: The AAR contrasts earlier Sales Tax jurisprudence treating both as a single transfer (Larsen & Toubro) but notes that such precedent does not dictate GST treatment where the taxable event is supply of services. Authorities on construction of tax notifications require strict interpretation.

Interpretation and reasoning: The AAR finds two independent taxable events: (i) supply by sub-contractor to main contractor; and (ii) supply by main contractor to contractee (Government). The statutory scheme and notifications that separately address sub-contractors confirm this bifurcation. Therefore benefits available to the main contractor under an exemption notification do not automatically apply to the sub-contractor's separate supply unless the notification text clearly includes the sub-contractor.

Ratio vs. Obiter: Ratio - Under GST, supply by sub-contractor to main contractor and the main contractor's supply to the contractee are independent taxable events; exemption eligibility must be assessed for each supply separately as per the text of relevant notifications.

Conclusion: The supplies constitute two independent taxable events and exemptions granted to the main contractor are not automatically applicable to the sub-contractor's procurement absent explicit inclusion.

Issue 3 - Applicable rate where exemption does not apply

Legal framework: In absence of nil-rating under Entry 3A to the sub-contractor's supply, standard GST rates as per the rate notifications apply. Notification 11/2017 (as amended) brings parity between main contractor and sub-contractor rates where applicable.

Interpretation and reasoning: Given that the sub-contractor's services are taxable and not covered by the exemption, the AAR applies the rate prescribed for such works contract services procured by a main contractor (as per applicable rate notification), resulting in a composite rate of 9% CGST + 9% SGST.

Ratio vs. Obiter: Ratio - Where a sub-contractor's supply to a main contractor is not covered by exemption entries, the applicable rate is the notified rate for such service; in the case at hand, that is 9% CGST + 9% SGST.

Conclusion: The taxable rate on the sub-contractor's supplies is 9% CGST + 9% SGST.

Cross-references and ancillary findings

- The Authority emphasizes that exemption notifications under Sec.11(1) must be strictly construed and conditions in the notification cannot be read in expansively.

- The AAR relied on documentary record on file; absence of complete supplementary documents led to reliance on material appended to the application for the ruling.

- Distinction between pre-GST Sales Tax jurisprudence and GST taxable event is critical: previous single-sale characterisation (transfer of property in goods) does not automatically apply to GST where the taxable event is supply of services.
