car tax deferral and the importance of applying in January

car tax is normally paid twice a year, in June and December. however, if you pay it all at once in January, the government will deduct a portion of the tax, known as the car tax deferral program.

the rate of deduction varies depending on when you apply, so the sooner you apply, the better. if you apply in January, you can save about 4.6% of your total annual tax bill, but the benefit tapers off to 3.7% in March, 2.5% in June, and 1.2% in September. so the smartest tax-saving strategy is to take advantage of the first opportunity you have between January 16 and the end of the month.

car tax discount rates for 2026 and how they are calculated

car tax is determined by the vehicle's displacement and age (the age of the car). based on non-commercial passenger vehicles, the tax per cc of displacement is as follows

  • 1,000 cc or less: 80 won per cc

  • 1,600cc or less: KRW 140 per cc

  • over 1,600cc: 200 won per cc

to this, a local education tax equal to 30% of the main car tax is added to determine the final tax amount.

in addition, there is a used car differential taxation system that reduces the tax by 5% per year for vehicles older than 3 years, up to a maximum of 50%, so the older the car, the lower the basic tax itself.

car tax refund process when transferring or scrapping a vehicle

a common concern for many people is what happens if you sell or scrap your car after making your payments. The bottom line is that you don't have to worry about it at all. once you transfer ownership of your vehicle or register it for scrapping, the municipality will prorate the amount of time you actually owned it and refund you the remaining taxes.

you can apply for a refund directly from the refund inquiry menu on the Weetax or eTax homepage, or by calling the tax department of your local ward office and providing them with the account number to which the refund should be credited. the refund is usually deposited within a month or so after the application.
