The short version
- Construction sites active for 150 days are considered fixed establishments.
- Businesses must register these sites as additional places of business.
- Inter-state movement of goods to these sites is a taxable supply.
In short
Teemage Builders asked if they needed GST registration in states where they assemble precast structures without a permanent office. The Authority for Advance Ruling (AAR) examined whether these temporary construction sites count as a fixed establishment under the Goods and Services Tax (GST) law.
What has changed
How it worked before
Many construction firms assumed that temporary project sites did not require separate GST registration if they lacked a permanent office or fixed infrastructure in that state.
What has changed
The authority ruled that a site operating for 150 days has sufficient human and technical resources to be a fixed establishment. This means you must register each site as an additional place of business in that state, and moving goods there is treated as a taxable supply.
Who this affects
Construction companies, precast manufacturers, and contractors who move materials and staff to project sites across different states.
An example
A construction firm from Karnataka sends precast walls to a project in Kerala for a six-month assembly job. Based on this ruling, the firm should register the Kerala site as an additional place of business. They cannot assume they are exempt from registration just because the site is temporary.
What you should do
If you operate similar construction sites, evaluate if your presence meets the criteria for a fixed establishment. Remember that an advance ruling only binds the company that asked and its specific tax office; it is not a general law for all businesses.
If you do nothing
If you fail to register a site that is later deemed a fixed establishment, tax authorities may issue notices for non-compliance. You could face penalties for failing to register or for incorrect tax reporting on inter-state transfers. Relying on this ruling without professional advice for your specific facts is risky.
The terms explained
- Fixed establishment
- A place other than your main office that has enough staff and equipment to carry out business activities for a significant period.
- Works contract
- A contract for construction, fabrication, or assembly where both goods and services are provided together.
- Supply
- Any transfer or sale of goods or services made for a business purpose, which often triggers a tax liability.

Questions before the authority
- Whether the applicant is required to obtain registration in the states in which it is executing works contract using precast structures manufactured at its principal place of business in Tirupur, when it has no fixed establishment in such state?
- Whether it is mandatory to register the site address (where there is only temporary office and no fixed establishment) as additional place of business if the site address is different from the registered office address but within the same state?
- Whether the transportation of material used in erection of the precast structures in the construction sites in other states, amounts to supply in the absence of consideration and in the absence of two different parties involved?
- Whether such transportation of manufactured elements and other raw materials for site work used for erection of the precast structures would require raising of invoice?
- If invoice is not required, can the movement of goods shall be made according to Rule 55 (1) (c) of the CGST Rules 2017 without support of invoice but with Delivery Challan?
- Whether it is mandatory to specify the tax rate in delivery challan (as per Rule 55 (1)) since we undertake only works contract and the rate of tax for the same is 18%, but the rate of tax for individual components (like cement) is 28% when they are sold separately?
- The delivery challan and e-way bill for manufactured elements and other raw materials for site work would contain GST rates and corresponding HSN codes, which would differ from the final invoice where SAC code for composite works contract would be mentioned. Would that be considered as a mismatch between HSN/SAC codes and GST rates in e-way bill and actual invoice, which is made at stage wise completion of construction, by the tax authorities?
- Similarly, in cases of movement of machineries (no transfer of ownership) to work sites, where there is no permanent establishment at the respective state and only used to perform the construction service, whether the difference in HSN/SAC codes and GST rates in e-way bill and actual composite supply invoice would be considered as mismatch?
- What document shall be issued for return of tools, equipments for return from worksite to our registered office?
- If tools, equipments and accessories which are returnable after work execution should be transported under delivery challan, what is the rate to be adopted in the delivery challan and e-way bill, whether contract rate or whether GST rate of the tools and equipments transported?
- If we are transferring materials and equipments between two sites at respective state where we do not have fixed establishment, what document shall be used for transportation of the same?
Facts
The applicant is engaged in the business of precast concrete construction, manufacturing structures at its Tirupur premises and transporting them to customer sites across India for assembly. The applicant maintains that it does not have a fixed establishment at these construction sites, as it only employs a small number of staff for a limited duration to perform the assembly. The applicant sought an advance ruling on registration requirements and various procedural aspects regarding the movement of goods and machinery.
Ruling
| Question | What the authority ruled |
|---|---|
| Registration in other states | Yes, the applicant is required to get registered in the state where the construction site is located. Based on the finding that the site constitutes a fixed establishment. |
| Registration of site address | Yes, the applicant may add such sites as additional places of business. Applicable when the site is within the same state. |
| Transportation as supply | Yes, it amounts to supply. Based on the interpretation of Schedule I and Section 25. |
| Procedural questions (d-k) | The question is not covered under the issues mentioned under Section 97(2) of the CGST Act 2017. Liable for rejection in terms of Section 98(2). |
The Authority ruled that the applicant is required to obtain registration in states where it executes works contracts, as the construction site constitutes a fixed establishment. Consequently, the applicant must register such sites as additional places of business if located within the same state. The Authority rejected the remaining questions (d through k) as they pertain to procedural requirements outside the scope of Section 97(2) of the CGST Act.
Reasoning
The Authority determined that the applicant's presence at construction sites, involving human and technical resources for a duration of approximately 150 days, meets the definition of a fixed establishment under Section 2(50) of the CGST Act. Regarding the supply of goods to these sites, the Authority relied on Section 7 and Schedule I, noting that transfers between distinct persons (as defined in Section 25) constitute a supply even without consideration. The remaining procedural queries were dismissed because they did not fall under the specific categories of questions admissible for an advance ruling under Section 97(2).
Provisions relied on
- Section 97(2) of the CGST Act 2017
- Section 98(2) of the CGST Act 2017
- Section 2(50) of the CGST Act 2017
- Section 7 of the CGST Act 2017
- Section 25 of the CGST Act 2017
- Schedule I of the CGST Act 2017
For the practitioner
This ruling clarifies that **precast construction sites** with a duration of around 150 days are likely to be treated as **fixed establishments**, necessitating state-specific GST registration. It confirms that inter-state movement of goods to such sites is a taxable supply under Schedule I. However, the ruling does not provide guidance on the procedural compliance issues (invoicing, delivery challans, and HSN mismatches) raised by the applicant, as the Authority deemed these outside its jurisdiction.
