CESTAT Rules Windmills Not Immovable Property, Quashes Service Tax Demand on Sundaram Fasteners
Tribunal Clarifies Windmills Can Be Dismantled and Relocated
Landmark Ruling Provides Relief to Industry, Limits Tax Liability
By Our Legal Reporter
New Delhi: January 22, 2026:
In a landmark judgment, the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) has ruled that windmills cannot be classified as immovable property. This decision came in the case of Sundaram Fasteners Ltd, where the tax department had raised a service tax demand, arguing that the company’s windmills constituted immovable property and attracted tax liability.
The tribunal’s ruling not only provides relief to Sundaram Fasteners but also sets a precedent for the renewable energy sector, clarifying the tax treatment of windmills under service tax law.
Background of the Case
- Sundaram Fasteners Ltd, a leading manufacturer of automotive components, had invested in windmills for power generation.
- The tax department issued a service tax demand, claiming that the windmills were immovable property and subject to tax.
- The company challenged the demand, arguing that windmills are movable assets since they can be dismantled and relocated.
- The matter reached the CESTAT, which examined whether windmills fall under the definition of immovable property.
Key Observations of the Tribunal
1. Windmills Are Movable Assets
- The tribunal noted that windmills can be dismantled, transported, and reinstalled at another location.
- This capability makes them movable property, not immovable property.
2. No Service Tax Liability
- Since windmills are not immovable property, they do not attract service tax under the category of renting or immovable property services.
- The tribunal quashed the tax demand raised against Sundaram Fasteners.
3. Relief for Industry

- It provides certainty in tax treatment, which is crucial for long-term projects.
For Tax Authorities
- The ruling sets a precedent, limiting the scope of service tax demands on movable infrastructure.
- It emphasizes the need for clear definitions in tax law.
For the Economy

Expert Opinions

Broader Context
This case is part of a larger debate on how infrastructure assets are classified under tax law. Similar disputes have arisen in the past regarding whether certain installations—like mobile towers or solar panels—constitute immovable property.
The CESTAT ruling adds clarity, reinforcing the principle that assets capable of relocation should be treated as movable property.
Practical Examples
- Case 1: A company installs windmills in Tamil Nadu but later shifts them to Gujarat. The tribunal’s ruling confirms that such relocation proves windmills are movable.
- Case 2: A solar farm dismantled and reinstalled elsewhere would also be treated as movable property, avoiding service tax disputes.
Challenges Ahead
- Legal Clarity: Tax laws must provide clearer definitions to avoid disputes.
- Implementation: Authorities must align their assessments with tribunal rulings.
- Future Disputes: Similar cases may arise with other renewable energy assets, requiring consistent interpretation.
