GST on engines varies by sub-classification under HSN 8407 and 8408, ranging from 12% to 28% depending on engine type, application, and power output. Most automotive vehicle engines attract 28%, while certain industrial sub-categories attract lower rates. This includes engines used in automotive applications, industrial machinery, generator systems, and commercial equipment. You encounter this engine tax in India when sourcing engines for manufacturing, replacement, or integration into heavy machinery. For an auto OEM procuring high-volume engine units at 28% GST, ITC recovery is typically the primary cost management tool.

What the Rate Means for Your Purchase Cost

The 28% GST significantly increases your procurement cost. If an engine costs ₹8,00,000, GST at 28% adds ₹2,24,000, making the total ₹10,24,000. For bulk procurement in the manufacturing sector or heavy machinery operations, this engine tax India directly impacts capital allocation and pricing decisions.

GST on Engine Parts and Accessories

GST on engine components is generally 28% under HSN 8409.
These costs are billed separately and increase spare engine tax, servicing, and maintenance cost.

How to Calculate GST on Engines

To calculate GST on engines, multiply the base price by 28%.

Formula:
Total cost = Base Price × 1.28

Example:
An engine priced at ₹8,00,000 results in ₹10,24,000 after GST. This excludes installation, transport, and compliance costs.

Impact of GST on Engine Prices

The GST structure influences pricing across automotive and industrial sectors.

Auto OEMs, generator suppliers, and heavy machinery operators benefit from predictable taxation.
High GST increases procurement cost for powertrain GST and engine units
Uniform taxation ensures consistency across spare engine tax and replacement parts
Classification-based taxation impacts pricing between engines and complete machinery

Input Tax Credit (ITC) on Engines

The GST framework offers structured advantages.

ITC on engines is available under GST rules.
This reduces your effective procurement cost and helps manage capital allocation in high-volume operations. ITC is not available where the engine is installed in a vehicle used for personal transport or non-business purposes.
You can claim ITC if engines are used for manufacturing or business operations
ITC applies to both new engine purchases and replacement units
Your business must be GST-registered and engaged in taxable supply

GST Reforms 2.0 on Engine Types

The 56th GST Council introduced GST rationalisation across several automotive and industrial categories. However, GST applicability on engines under HSN 8407 and 8408 continues to depend on the specific engine classification, application, and product category. Many standalone petrol and diesel engine categories commonly continue to attract 28% GST, though businesses should verify the latest applicable rate and official GST notifications before procurement.

Additional Costs to Consider

GST is only one component of your total engine purchase cost.

You should calculate these separately to estimate your total investment.
Installation and labour charges (18% GST)
Transport and logistics costs
Compliance, certification, and emission testing
Maintenance and spare parts replacement
