Annual car tax (estimate) (Non-commercial passenger car · for reference)
Enter values, then press Calculate.
※ Simplified formula for non-commercial passenger cars. Education tax, commercial vehicles, and EVs are not included. For reference — may differ from official notices.
How to use
- Enter engine displacement (cc). The default example is 1,598 cc. Use the displacement on the vehicle registration.
- Enter vehicle age (years). Default is 3 years; an approximate table applies reductions from year 3.
- Press Calculate for tax per cc, base annual tax (displacement × per-cc rate), amount after age reduction, and the reduction rate.
- Education tax, commercial-use, and EV special rules are not on this screen. Only the non-commercial passenger displacement formula is covered.
- Reset restores 1,598 cc and 3 years. Installment notice dates are not shown—only an annual-tax approximation.
Key concepts
This automobile tax calculator estimates Korea’s non-commercial passenger car tax, displacement rates, and age reductions. Typically a per-cc rate is set by cc bracket, multiplied by displacement for a base annual tax, then reduced by a percentage based on vehicle age. This tool simplifies to 18 KRW/cc at 1,000 cc or less and 1,600 cc or less, 19 KRW in the next bracket, and 24 KRW above that. It matches searches for annual car tax, age discounts, and per-cc rates before a notice.
The approximate table steps down from 95% in year 3 to about 50% from year 12. Local education tax, commercial use, and EV/hydrogen flat amounts are not included. Wetax/Etax notices can differ in tax base and age start date, so enter registration displacement and model year as-is and treat this as a guide. Results are for reference and may differ from local-government notices.
Example
1,598 cc, age 3 years: 18 KRW per cc, base annual tax 28,764 KRW, 95% reduction, 27,326 KRW after age reduction. Lower age to 2 years and 28,764 KRW stays with no reduction. At the same age, 2,000 cc is 19 KRW per cc, base 38,000 KRW. From age 12 the reduction rate is 50%, half the base. Calculating with on-screen defaults should match the first example. Change fields and calculate again under the same rules. For filings, pay, and contracts, official notices and agreements take priority. These figures are for reference.

Frequently asked questions
How does automobile-tax age reduction work?
An approximate table steps down from year 3 to about 50% from year 12. Year 3 is 95%. For reference only.
Can this calculator do EV automobile tax?
This version covers only the displacement-based non-commercial passenger formula. EVs use a different flat system and are unsupported. For reference only.
Is automobile tax paid twice a year?
Payment is usually in installments, but here only an annual-tax approximation is shown. See local-government guidance for installment notices. For reference only.
What about commercial-vehicle automobile tax?
The rate system differs and is unsupported. Enter non-commercial passenger only. For reference only.
Is education tax included in automobile tax?
Not included. See education tax and extras on the notice separately from this number. For reference only.
Is the automobile-tax calculator an exact notice amount?
For reference only. It may differ from local-government notices.
