The short version
- Precision Automation asked how car parking system installation is taxed under GST.
- Maharashtra AAR ruled that installed parking systems count as immovable property.
- The supply and installation is classified as a works contract under GST.
- Systems require customized civil foundations and cannot be moved without dismantling.
In short
Precision Automation and Robotics India Limited asked the Maharashtra Authority for Advance Ruling (AAR) under order GST-ARA- 39/2017-18/B- 46 whether supplying and installing automated car parking systems counts as a sale of goods or a works contract. The company manufactures, erects, and integrates multi-level stacker, puzzle, and tower parking structures on customer sites. Because these systems need specialized concrete foundations and cannot be shifted without completely breaking them down into parts, the company needed clarity on their GST treatment.
What has changed
How it worked before
Before this ruling, equipment suppliers and engineering contractors were uncertain whether multi-level parking systems were moveable machinery taxed as a sale of goods or civil structures taxed as works contracts. This led to confusion over the correct GST rate and whether customers could claim input tax credit.
What has changed
The authority decided that installing a tailored car parking system results in immovable property because it becomes permanently attached to the building or land. As a result, the entire job of designing, supplying, erecting, and commissioning these systems is classified as a works contract under Section 2(119) of the CGST Act. For businesses, this means tax must be charged under the GST rules for works contracts rather than a standard sale of goods.
Who this affects
Manufacturers of automated parking systems, engineering procurement construction contractors, and real estate developers installing multi-level parking structures.
An example
Horizon Builders in Mumbai contracts a local engineering firm to design and install a 50-car puzzle parking system on a custom concrete slab for a residential project. The engineering firm wonders whether to invoice the project as a sale of machinery or as a construction service. Based on the logic in order GST-ARA- 39/2017-18/B- 46, because the system cannot be moved without total dismantling, the tax authority views this as creating immovable property. The firm would likely need to treat the entire turnkey project as a works contract under GST.
What you should do
Remember that an advance ruling binds only the company that applied for it and their local tax office. If your business installs similar structures, do not automatically copy this tax treatment without checking with a qualified GST advisor or applying for your own advance ruling.
If you do nothing
If you treat the installation as a simple sale of goods when your local tax officer considers it a works contract, you risk receiving a demand notice for unpaid GST along with interest and penalties. Your customers might also face problems claiming input tax credit if the tax invoice uses the wrong classification. Resolving these disputes after an audit can cost significant time and money.
The terms explained
- works contract
- A contract where supply of goods and services happens together to build, erect, install, or repair immovable property like buildings or fixed structures.
- immovable property
- Land or any structure or machinery attached to land in a way that it cannot be moved without dismantling or causing heavy damage.
- input tax credit
- The GST a business pays on its business purchases, which it can subtract from the GST it collects on its final sales.

Questions before the authority
- Whether the activity of supply and installation of 'car parking system' would qualify as immovable property and thereby 'works contract' as defined in Section 2(119) of the CGST Act.
Facts
The applicant is engaged in the business of design, manufacturing, procurement, erection, and installation of various types of car parking systems, such as stacker, puzzle, and tower parking systems. The process involves creating tailored civil foundations, erecting steel structures, assembling components, integrating electrical systems, and commissioning at the customer's premises. Once installed, the car parking system cannot be moved as-is without complete dismantling into parts and components.
Ruling
| Question | What the authority ruled |
|---|---|
| Supply and installation of car parking system as works contract | Answered in the affirmative Qualifies as works contract under Section 2(119) of CGST Act as it results in immovable property. |
The Authority held that the supply and installation of a car parking system results in an immovable property. Consequently, the transaction constitutes a **works contract** under Section 2(119) of the Central Goods and Services Tax Act, 2017.
Reasoning
The Authority analyzed the operational steps and physical nature of the installation, noting that a car parking system is customized to a specific building or land and requires site-specific foundation and steel/RCC structures. Once assembled and operational, it attains a state of permanency and cannot be shifted to another site without complete dismantling involving loss or damage. Applying tests established by the Supreme Court in decisions like **T.T.G. Industries Ltd.** and **Solid and Correct Engineering Works**, the Authority concluded that the installation is permanently annexed to the earth/building for its beneficial enjoyment. Since the process involves transfer of property in goods in the execution of building, erecting, and commissioning an immovable property, it satisfies the criteria for a **works contract** under Section 2(119) of the CGST Act.
Provisions relied on
- Section 2(119) of the CGST Act, 2017
- Section 2(30) of the CGST Act, 2017
- Section 3(26) of the General Clauses Act, 1897
- Section 3 of the Transfer of Property Act, 1882
For the practitioner
This ruling establishes that turnkey engineering projects involving tailored site assembly, erection, and structural integration—such as automated car parking systems—are to be classified as **works contracts** rather than mere sales of goods. It benefits EPC contractors and mechanical system suppliers seeking clarity on immovability parameters under GST. The ruling specifically addresses the works contract definition and explicitly refrains from deciding alternative composite supply classifications.
