Korea Car Tax 2026: How Much for a 2.0L Sedan and How to Save 10%
Everything you need to know about Korea's annual car tax — rates by engine size, age-based discounts, January prepayment savings, and how to avoid late penalties.
A friend of mine just bought a 2.0L sedan and panicked when the first tax notice arrived. He thought car tax in Korea was a one-time deal at registration. Nope. Every year in June and December, the government sends a bill based on how many cc's your engine has. For a 2,000cc car, that's about 520,000 won a year before any discounts.
The good news is there are real ways to lower that bill. Pay it all in January and you knock off 10%. Drive the same car for more than three years and it starts shrinking automatically. Most owners just pay whatever shows up on the notice without realizing they left money on the table. Let's walk through how the tax is actually built so you can see where the savings hide.
What you'll learn
- ✅How Korea's annual car tax is calculated by engine displacement
- ✅Age-based discounts that start in year three and max out at 50%
- ✅How the January prepayment saves you 10% every year
What Is 자동차세?
Car tax (자동차세) in Korea is an annual local tax you pay just for owning a registered vehicle. It's separate from the acquisition tax you paid when you bought the car. The tax has two parts: the main tax based on engine displacement, and an education surtax equal to 30% of the main tax. Both show up on the same bill, so most people don't even notice the split.
The bill is issued twice a year. The first half covers January through June and is due by the end of June. The second half covers July through December and is due at the end of December. If you sell or scrap the car mid-year, the tax is prorated by day.
Tax Rates by Engine Size
The rate per cc depends on whether the car is for personal use or commercial use such as a taxi or rental. Commercial rates are significantly lower. Here's the full breakdown.
| Engine size | Personal use (per cc) | Commercial use (per cc) |
|---|---|---|
| 1,000cc or less | 80 won | 18 won |
| 1,001 to 1,600cc | 140 won | 18 won |
| 1,601 to 2,000cc | 200 won | 19 won |
| 2,001cc or more | 200 won | 24 won |
| Small van | 65,000 won flat | 25,000 won flat |
| 1-ton truck | 28,500 won flat | 6,600 won flat |
So a 1,998cc personal sedan pays 1,998 x 200 = 399,600 won as the main tax, plus 30% education surtax of 119,880 won, for a total of about 519,480 won per year. Commercial taxis with the same engine pay a fraction of that — the government cuts them a huge break.

Car Tax Calculator →Age-Based Discount: Starts in Year 3
Here's the part most drivers don't know about. Once your car turns three years old, the main tax starts dropping by 5% each year. It keeps dropping until it hits a 50% cap in year twelve. That's why older cars cost peanuts to keep on the road from a tax perspective.
- Years 1 to 2: Full rate, no discount
- Year 3: 5% off the main tax
- Year 4: 10% off
- Year 5: 15% off, with 5% added every year after
- Year 12 and beyond: Maxed out at 50% off
Important detail: the discount applies only to the main tax, not to the education surtax. And the year count is based on the registration date, not the model year. A 2023-model car registered in December 2023 hits year 3 on January 1, 2026 — sometimes earlier than buyers expect.
The January Prepayment Discount
Pay the full year's tax in January and the government gives you a 10% discount on the annual total. This is the single biggest saving most owners miss. The prepayment window opens mid-January and closes at the end of the month. There are smaller discount windows later in the year too, but none come close to January's.
- January prepayment: 10% off the entire year
- March prepayment: roughly 7.5% off the remaining portion
- June prepayment: roughly 5% off the second half
- September prepayment: roughly 2.5% off the second half
Set a calendar reminder for mid-January
Open the Wetax app or visit wetax.go.kr between January 16 and January 31, find your vehicle, and select the prepayment option. The 10% discount is applied automatically at checkout. For a 2.0L sedan paying 520,000 won, that's 52,000 won saved for 30 seconds of tapping. If you miss January, you can still apply in March, June, or September for smaller discounts — but January is by far the best deal, so put a reminder in your phone now.
Worked Example: 2.0L Sedan, 5 Years Old
Let's run the numbers for a real case — a 1,998cc personal sedan that was registered in early 2021. In 2026 it turns five years old, so it qualifies for the 15% age discount. The owner also signs up for January prepayment.
2.0L sedan, year 5, January prepayment
So the same car that cost 519,480 won a year when it was new now costs 397,402 won — a 122,000 won annual savings just from age plus January prepayment. Keep the car past year twelve and you cap out at a 50% age discount, bringing the total closer to 260,000 won a year.
How to Pay and What Happens If You're Late
You can pay through the Wetax app, your bank's mobile banking app, at any bank or convenience store, or through auto-debit. Most people use Wetax because it handles the prepayment discount, age discount, and education surtax all in one transaction.
Miss the deadline and things get ugly fast. Korea adds a 3% penalty the day after the due date. Then a heavy surcharge of 0.66% per month kicks in for up to 60 months. If you keep ignoring it, the government can seize your bank account, garnish your salary, or even auction off your car. The car also can't pass its next inspection until the tax is cleared.
Don't let the bill slide into the next month
I've seen people rack up over 20% in penalties just by forgetting a car tax bill for a year. The 3% initial penalty hits immediately on the first day late, and the monthly surcharges pile up fast. If money is tight, at least log into Wetax and apply for an installment plan before the due date — the penalty on a paid-in-installments bill is way smaller than the penalty on an ignored one.
Frequently Asked Questions
I sold my car in August. Do I still owe tax for the whole year?
No, the tax is prorated by day. You owe tax from January 1 up to the transfer date, and the buyer owes tax from the transfer date to the end of the year. If you already prepaid the full year in January, the city refunds the unused portion automatically — it shows up in your account within about a month.
Does the age discount apply to electric vehicles?
EVs have a flat annual tax of 100,000 won for personal use, plus the 30% education surtax, so 130,000 won total. The age discount doesn't really apply because the tax isn't based on cc's. The flat rate is already way lower than a gas car, so EV owners usually don't need to worry about this part.
My car is 12 years old. Is there really a 50% discount?
Yes, once the car hits year 12 counted from the registration date, not the model year, the main tax is cut in half and stays there for the rest of the car's life. A 2.0L sedan that paid 520,000 won brand new ends up around 260,000 won a year. Keep a car long enough and car tax basically stops being a big deal.
I missed January prepayment. Is March worth it?
March gives you about a 7.5% discount on the remaining portion, which is smaller than January's 10% but still better than paying the regular bill. If you miss January, March is worth doing. June and September windows exist too but the discount is small enough that most people just pay the regular bill at that point.
Commercial taxis pay way less. Can I register my car as commercial?
Only if you actually operate it as a commercial vehicle with proper licensing — taxi, rental, delivery, and so on. You can't just flip a switch to get the lower rate. The tax office checks commercial registration against your business license, and trying to fake it is tax fraud. If you're running a real business, the commercial rate is a legitimate benefit though.
