The GST treatment for motor vehicles in Singapore differs from normal business assets due to specific rules on input tax restriction and output tax requirements. As clarified by the Inland Revenue Authority of Singapore (IRAS), businesses must carefully determine whether GST is claimable on purchase and how GST should be accounted for upon sale.
Therefore, understanding these rules is essential to avoid common GST errors, especially for companies owning vehicles or motor vehicle dealers.
1. Input Tax on Purchase of Motor Vehicles
To begin with, the GST treatment depends on the type of vehicle purchased.
(a) Motor Cars – Input Tax Not Claimable
Generally, GST incurred on the purchase and running expenses of a motor car is not claimable.
This includes costs such as:
- Purchase price of the car
- Petrol and maintenance
- Parking expenses
This restriction applies under GST regulations, except for specific excluded categories (e.g. certain commercial use cases).
(b) Other Motor Vehicles – Input Tax Claimable
On the other hand, GST incurred on non-motor car vehicles is claimable, subject to normal conditions.
For example:
- Lorries
- Vans
- Motorcycles
In such cases, businesses can claim input tax if the vehicle is used for making taxable supplies.
2. GST Must Be Charged When Selling the Vehicle
Importantly, GST must still be accounted for when selling a vehicle.
In fact:
👉 You must charge GST on the sale even if you did not claim input tax on purchase
This is a very common misunderstanding among businesses.
Therefore, regardless of whether input tax was disallowed earlier, the sale of the vehicle is still considered a taxable supply.
3. GST Treatment for Sale of Used Vehicles
Furthermore, IRAS provides specific schemes for selling used motor vehicles.
(a) Discounted Sale Price Scheme (Most Common)
If you are not a motor vehicle dealer, or do not qualify for other schemes:
- GST is charged on 50% of the selling price
Example:
If selling price = $20,000
GST applies on $10,000 only
This scheme applies commonly when:
✔ A business sells its own company vehicle
✔ Input tax was not claimable
(b) Gross Margin Scheme (For Dealers)
On the other hand, motor vehicle dealers may use the Gross Margin Scheme, subject to conditions.
Under this scheme:
- GST is charged on the profit margin (selling price – purchase price) instead of full value
However, strict conditions apply, and incorrect use may result in penalties.
4. Key Principle: Sale of Business Asset is Taxable
In addition, IRAS emphasises an important rule:
👉 The sale of a business asset is subject to GST regardless of:
- Whether it is part of your normal business activity
- Whether input tax was claimed earlier
Therefore, even a one-off disposal of a company vehicle is still a taxable supply.
5. Common GST Mistakes (Very Important)
In practice, businesses often make the following mistakes:
❌ Not charging GST because input tax was disallowed
❌ Charging GST on full selling price instead of 50% (wrong scheme)
❌ Using Gross Margin Scheme without meeting conditions
Consequently, these errors may lead to under-declaration or overpayment of GST.
6. Practical Example
Let’s illustrate the rules clearly:
Scenario:
- Company buys a motor car (GST not claimable)
- Later sells the car for $30,000
Correct GST treatment:
- Apply Discounted Sale Price Scheme
- GST charged on 50% of selling price
👉 GST = $30,000 × 50% × 9% = $1,350
Key Takeaways
| Topic | Treatment |
|---|---|
| Motor car purchase | Input GST not claimable |
| Commercial vehicles | Input GST claimable (if conditions met) |
| Sale of vehicle | GST must be charged |
| Used vehicle sale | GST on 50% of selling price (common case) |
| Dealer scheme | Gross Margin Scheme may apply |
Final Thoughts
In summary, the GST treatment for motor vehicles in Singapore involves two key principles:
- Input tax restriction for motor cars
- Mandatory output tax when the vehicle is sold
Although the rules may appear counterintuitive — especially when GST was not claimable on purchase — businesses must still account for GST upon disposal.
Therefore, companies should carefully review their vehicle transactions and ensure the correct GST scheme is applied.
