Can my car be a business expense? — Tax saving tips for small business owners in S. Korea

Can I take advantage of my car by reporting it as a business vehicle?

Yes, you can. You can report a business vehicle expense up to KRW 15,000,000 a year.


According to Korean income tax law, you can deduct your vehicle expense which is only related to ‘business usage’. The business usage amount is computed as ‘business usage mileage’ divided by a ‘total mileage’.

The term ‘business usage mileage’ refers to the distance traveled to perform business such as commuting to work, visiting business sites, vendors, clients, and attending meetings.

To keep track of this business usage mileage, the NTS(National Tax Service) requires to update a business mileage journal of the following form.

Business Vehicle Mileage Report (업부용승용차 운행기록부) provided by NTS


Now, it looks VERY tedious to keep a diary of the business vehicle and the tax office also understands you are too busy to manage your business itself afloat. If you choose not to write this Business Vehicle Mileage Report, then a default expense limit of KRW 15 MIL would be applied.


What are the business vehicle expenses then?

General automobile costs such as repairs, gas, tires, parking fee, and auto insurance premiums are tax-deductible items.

Please note that 5-year useful life will be used to compute the depreciation cost of your car. In other words, when you purchase a car for KRW 30MIL the depreciation cost is KRW 6MIL per year, which is derived by 30MIL / 5 years.

There is a lawful limit to this depreciation cost (KRW 8MIL per car), hence no matter how high valued car you bought for your business, you can only deduct a maximum of KRW 8MIL per year. (This KRW 8MIL limit is included in the annual expense limit of KRW 15MIL).


If the car is under my spouse’s name and I use it mostly to work, can I still report it as a business expense?

YES you can. As long as you can prove that the car was used for your business, the tax office allows you to deduct the expense from business income (This is only related to the self-employed person or 개인사업자, I will write about Corporate car expense later)
