A complete guide for employees and employers in Singapore to understand car benefit taxation rules, how IRAS calculates the taxable value, and how to stay compliant while optimising your tax position.
📌 What Are Car Benefits?
In Singapore, car benefits refer to the provision of a motor vehicle by an employer for an employee’s use, either for business or personal purposes. When the car is available for personal use, the benefit-in-kind is taxable under the Inland Revenue Authority of Singapore (IRAS) guidelines.
Tax applies regardless of whether the vehicle is owned, leased, or rented by the company, and regardless of whether the car is driven by the employee or a driver provided by the employer.
💼 When Are Car Benefits Taxable?
- When a company car is made available for private use.
- When fuel, maintenance, insurance, and other running costs are paid by the employer.
- When the vehicle is used outside of business purposes.
If the car is used solely for business and is parked at the company premises after work hours, it may be exempt from tax.
🧮 How IRAS Calculates Car Benefits
The taxable car benefit is generally calculated using the following formula:
Annual Value of Car Benefit = (Annual Car Value × % Private Use) + (Fuel Benefit, if applicable)
For owned cars, IRAS uses a prescribed annual car value based on the Open Market Value (OMV) of the vehicle, depreciation rates, and age of the car.
For leased cars, the taxable value is generally based on the actual lease cost plus any running expenses covered by the employer.
🚗 Components of Car Benefit Calculation
- Car Ownership Type: Owned, leased, or rented affects calculation method.
- Car’s OMV: Determines depreciation-based annual value.
- Fuel Costs: If paid by employer, an additional taxable benefit applies.
- Maintenance & Insurance: Included if covered by the company.
- Private Use Percentage: Higher private use means higher taxable value.
📊 Example Tax Calculation
Suppose an employer provides a car with an OMV of SGD 80,000, 5 years old, and the employee uses it 50% for personal use. Employer also pays for fuel worth SGD 2,000 annually.
- Annual Car Value (based on OMV & age) = SGD 12,000
- Private Use Portion = 50% × SGD 12,000 = SGD 6,000
- Fuel Benefit = SGD 2,000
- Total Taxable Car Benefit = SGD 8,000
🚫 Non-Taxable Situations
- Car used exclusively for business purposes.
- Carpooling arrangements for staff transport without personal use.
- Vehicles provided to disabled employees for mobility assistance.
🛠️ Tips for Employees & Employers
