A company car, monthly car allowance or paid parking can help reduce your transport expenses. However, even when your employer pays the bill, you may still have to pay personal income tax on the benefit you receive.
This does not mean you pay tax equal to the cost of the benefit. Instead, its taxable value is added to your employment income when calculating your income tax. How much is included depends on whether your employer provides a car, pays you an allowance or reimburses specific expenses.
If Your Employer Provides A Car, How Much Is Taxable?
You do not have to include the car’s entire purchase price in your annual income.
Instead, IRAS calculates the taxable value using a formula that accounts for the car’s cost and the running expenses your employer pays.
For a new car purchased by your employer and provided to you for the full year, the formula is:
Annual taxable car benefit = 3/7 × [(Car cost − PARF rebate) ÷ 10 + Employer-paid running and maintenance costs]
The car cost includes its Certificate of Entitlement (COE). The Preferential Additional Registration Fee (PARF) rebate is the amount that would be payable if the car were deregistered at more than nine but no more than 10 years old. The 3/7 multiplier represents IRAS’ estimate of private use outside office hours.
To see how this works, assume your employer buys a new car for $200,000, with an applicable PARF rebate of $10,000, and provides it to you for a full year. It also pays $5,000 in running and maintenance expenses.
| Calculation | Amount |
| Subtract the PARF rebate from the car cost: $200,000 − $10,000 | $190,000 |
| Divide this amount by 10 | $19,000 |
| Add annual running and maintenance expenses: $19,000 + $5,000 | $24,000 |
| Multiply the total by 3/7 | Approximately $10,286 |
In this example, $10,286 is added to your annual employment income. This is the taxable value of the car benefit, rather than the amount of income tax you must pay.
Running and maintenance expenses can include petrol, insurance, road tax, parking, Electronic Road Pricing (ERP) charges and repairs. The 3/7 multiplier applies to both the annual car-cost component and these expenses.
Different formulas apply to second-hand cars and cars with renewed COEs. If your employer leases a car for you, the taxable value is generally 3/7 × (rental cost + applicable running and maintenance expenses paid by your employer).
If You Receive A Car Allowance, Is The Full Amount Taxable?
A cash car allowance is taxable in full. For example, if your employer pays you $1,000 a month, the full $12,000 a year is included in your employment income. The 3/7 formula for a company-provided car does not apply to this allowance.
However, reasonable reimbursement for business mileage in your own car is not taxable. IRAS does not set a prescribed mileage reimbursement rate, so the amount depends on your company’s policy.
Do You Pay Tax On Employer-Paid Parking And ERP?
If you drive your own car, paid parking or ERP expenses may seem like straightforward work benefits. However, the tax treatment differs depending on what the payment covers.
| What your employer pays for | Taxable to you? |
| Parking at or near the office when you drive from home to work | Yes |
| Parking reimbursement for client meetings | No |
| Airport parking reimbursement when you go on a business trip | Yes |
| A fixed ERP allowance | Yes |
| Reimbursement of ERP charges incurred for work | No |
| Your own car’s road tax, repairs or maintenance | Yes |
Airport parking is one detail worth checking: the reimbursement is taxable even when you park there to take a business trip. Parking reimbursement for a client meeting, on the other hand, is not taxable.
What If Your Employer Provides A Chauffeur?
If your employer provides a chauffeur, the portion attributable to private travel is taxable to you. This is calculated by multiplying the annual driver cost by private mileage as a share of total mileage.
For example, if the driver costs $60,000 a year and 40% of the mileage is for your private travel, the taxable chauffeur benefit is $24,000. That amount is included in your employment income.
How Does This Affect Your Actual Tax Bill?
A taxable car benefit increases the income used to calculate your tax. In our earlier example, the company car adds approximately $10,286 to your employment income, but the additional tax you pay depends on your overall income, applicable reliefs and tax rate.
When assessing a job offer, check which car expenses your employer covers, whether private use is allowed and what taxable value will be reported. These benefits can still save you money, but knowing how they affect your income tax gives you a clearer picture of what the package is worth.
