The short version
- Tamil Nadu Water Investment Company asked if their services were exempt.
- The Authority ruled these services qualify as 'Pure Services'.
- The recipient, CMWSSB, is classified as a 'Governmental Authority'.
In short
The company asked if their project management and consultancy work for the Chennai Metro Water Supply and Sewerage Board (CMWSSB) should be taxed under the Goods and Services Tax (GST). The dispute arose because the board refused to pay GST, claiming the services were exempt under government notifications. The Authority examined whether these services qualified as 'Pure Services' provided to a government body for municipal functions.
What has changed
How it worked before
It was unclear to many businesses whether consultancy services provided to state-run utility boards qualified for the specific 'Pure Services' tax exemption.
What has changed
The Authority confirmed that services related to water supply and sewerage, when provided to a government-controlled entity, are exempt from GST. This means businesses performing similar public utility consultancy work can now argue their services are tax-exempt, provided they meet the same criteria.
Who this affects
Consultancy firms and project management companies working on public utility projects for state-run boards or government authorities.
An example
Imagine a private engineering firm provides consultancy for a state-run electricity board. They might ask if their services are exempt under the same notification. Based on this ruling, if the board is a 'Governmental Authority' and the work relates to municipal functions, the firm could argue for an exemption. However, they must confirm their specific client meets the legal definition of a government authority first.
What you should do
If you provide similar services, review your contract and the status of your client to see if they qualify as a 'Governmental Authority'. Remember, an Advance Ruling only binds the company that asked and their specific tax office; it is not a universal law that automatically applies to your business.
If you do nothing
If you stop charging GST based on this ruling without confirming your specific situation, you risk a tax demand if an officer disagrees with your interpretation. You would then be liable for the unpaid tax, plus interest and potential penalties. Always seek professional advice before changing your tax collection practices.

The ruling in detail
Authority for Advance Ruling
M/s. Tamil Nadu Water Investment Company Limited
ORDER No.21 /AAR/2018 DATED 28.11.2018 · Tamil Nadu
Questions before the authority
- Whether Sl.No.3 of Notification No. 12/2017-Central Tax (Rate) dated 28th June 2017 is applicable for the services rendered by Tamil Nadu Water Investment Company to Chennai Metro Water Supply and Sewerage Board.
Facts
The applicant provides project management consultancy and consultancy services for water supply and sewerage projects to the Chennai Metro Water Supply and Sewerage Board (CMWSSB). The applicant sought a ruling on whether these services qualify as exempt 'Pure Services' provided to a governmental authority under the relevant GST notification. The CMWSSB had previously declined to reimburse the GST component, arguing the services were exempt.
Ruling
| Question | What the authority ruled |
|---|---|
| Applicability of exemption under Sl.No.3 of Notification No. 12/2017-CT(R) | Exempt Services qualify as Pure Services provided to a Governmental Authority |
The Authority ruled that the services provided by the applicant to CMWSSB are exempt from CGST and SGST. It concluded that the applicant is supplying 'Pure Services' to a 'Governmental Authority' relating to functions entrusted to a municipality under the Twelfth Schedule of the Constitution.
Reasoning
The Authority determined that CMWSSB is a 'Governmental Authority' as it was constituted by a state act with 100% government contribution to carry out functions listed in Article 243W of the Constitution. The services provided, including project management and consultancy for water supply and sewerage, fall under the functions entrusted to a municipality. Consequently, the activity satisfies the criteria for **exemption under Sl.No.3 of Notification No. 12/2017-Central Tax (Rate)**. The ruling relied on the definition of 'Governmental Authority' under Section 2(16) of the IGST Act and the scope of 'Pure Services' as defined in the notification.
Provisions relied on
- Sl.No.3 of Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017
- Section 2(16) of the Integrated Goods and Services Tax Act, 2017
- Article 243W of the Constitution of India
- Twelfth Schedule of the Constitution of India
For the practitioner
This ruling confirms that consultancy services provided to a state-controlled water board for municipal functions qualify for the **exemption for Pure Services**. It provides a clear precedent for similar entities to claim exemption when contracting with governmental authorities for public utility projects. Practitioners should note that this decision is specific to the applicant's contractual scope and the status of the recipient as a governmental authority.
