EPC Contracts for Solar Projects Taxed at 5% Rate for Standalone Parts

The ruling determined that the EPC contract for solar power plants is classified as a works contract and taxed accordingly. Parts supplied on a standalone basis with PV modules qualify for a concessional tax rate of 5%. Sub-contractors are eligible for the 5% rate if the sub-contract is solely for goods supply; otherwise, the main contractor's tax rate applies.

Issues Involved:
1. Separate taxability of goods and services in solar power plant contracts.
2. Concessional tax rate for parts supplied on a standalone basis.
3. Availability of concessional tax rate to sub-contractors.

Detailed Analysis:

Issue 1: Separate Taxability of Goods and Services in Solar Power Plant Contracts
The applicant, engaged in setting up solar power plants, sought clarity on whether separate contracts for goods and services would attract different tax rates. The authority examined the nature of the EPC (Engineering, Procurement, and Commissioning) contract, which involves designing, sourcing, constructing, and commissioning the power plant. The authority determined that such contracts are inherently "works contracts" as defined under Section 2(119) of the CGST Act, 2017, which involves the transfer of property in goods and services related to immovable property. The authority concluded that the EPC contract cannot be artificially divided into separate contracts for goods and services, and thus, the entire contract should be treated as a works contract, taxable under item (ii) of entry no. 3 of Notification No. 11/2017-Central Tax (Rate) dated 28.06.2017 up to 31.12.2018. From 01.01.2019, the contract is taxable on the values separately worked out for goods and services under entry no. 38 of Notification No. 11/2017-Central Tax (Rate) and Entry No. 234 of Schedule I of Notification No. 1/2017-Central Tax (Rate).

Issue 2: Concessional Tax Rate for Parts Supplied on a Standalone Basis
The applicant inquired whether parts supplied on a standalone basis, when supplied with PV modules, would be eligible for a concessional tax rate of 5%. The authority referred to Notification No. 1/2017-Central Tax (Rate), which specifies that renewable energy devices and parts for their manufacture falling under Chapters 84 or 85 are taxable at 5%. The authority affirmed that parts supplied on a standalone basis would be eligible for the concessional rate of 5% as long as they are parts of the solar power generating system.

Issue 3: Availability of Concessional Tax Rate to Sub-Contractors
The applicant sought clarity on whether sub-contractors would also be eligible for the concessional tax rate of 5% on parts of the solar power generating system. The authority referred to Entry No. 234 in Schedule I to Notification No. 1/2017-Central Tax (Rate), which does not differentiate between supplies by the contractor or the sub-contractor. It was concluded that the concessional rate of 5% would be available to sub-contractors if the sub-contract is solely for the supply of goods. However, if the entire EPC contract is sub-contracted, the rate of tax applicable would be the same as that applicable to the main contractor.

Ruling:
1. The EPC contract is considered a works contract under section 2(119) of the CGST Act and is taxable accordingly up to 31.12.2018. From 01.01.2019, it is taxable on the values separately worked out for goods and services.
2. Parts supplied on a standalone basis (when supplied with PV modules) are eligible for a concessional tax rate of 5%.
3. The concessional rate of 5% is available to sub-contractors if the sub-contract is only for the supply of goods. If the entire EPC contract is sub-contracted, the tax rate applicable to the main contractor applies.
